Significant infrastructure such as roads, prisons, schools, rail tracks and train systems, among others are currently developed through the involvement of Public Private Partnership (PPP) arrangements which have been acknowledged internationally in recent time. The poor management of end-user stakeholder during PPP projects in developing nation like Nigeria has been established as one of the major factor affecting the successful growth and development of PPP projects. Due to the paucity in research on end-user stakeholder management on PPP projects in Nigeria, informs this study aim to expose the main strategic factors that can accommodate end-user stakeholder’s management in any PPP road project in Nigeria. The professionals that have worked on the project cum the end-user of the project area were used as targeted respondents for the adopted case study and survey strategies method approach. Thematic analysis was used to analyse the eighteen (18) interviews that were conducted having completed and analysed total number of 282 questionnaires using reliability and factor analysis approach. Seven valid underlying factors were revealed from 28 variables that were left on the questionnaire data with the aid of factor analysis which were used later as factors affecting end-user stakeholders’ management in PPP road project in Nigeria. A proposed framework was created with the seven underlying factors as a template for any successful PPP road project in developing country like Nigeria. These will quench the agitation of enduser stakeholders’ quarrels on PPP toll road projects
Identify Current Deficiencies in Public Private Partnership Practices and Are...IJERA Editor
Public- Private Partnerships is becoming a popular investment model since late 1980s and 1990s in the world.
PPPs in the delivery of public services have become a phenomenon which is spreading around the globe and
generating great interest among governments, investors and other key project stakeholders. Public- Private
Partnerships avoid the often negative effects of either exclusive public ownership or outright privatization. This
is seen as a win-win situation for both public and private entities where they undertake large scale projects. This
balanced approach is especially welcomed in public services which touch on every human being‟s basic needs
& economic development of a country.
Basically in this research, it is attempted to address three main objectives, which are to identify the current
Public- Private Partnerships coverage on infrastructure projects in Sri Lanka, to identify current deficiencies in
Public- Private Partnerships practices and areas which resist Public- Private Partnerships being an attractive
investment model in infrastructure developments in Sri Lankan context and to propose an improved PublicPrivate
Partnerships framework/model that can be used effectively and address the identified problems in
infrastructure developments in Sri Lanka.
Based on a structured questionnaire, data collection has been done using a selected sample. Then, the data set
has been evaluated using Likert Scale and giving weights for that and the total percentage of score.
Lack of the knowledge and deficiencies of the PPP framework are main issues in PPP practice in Sri Lanka.
Thus, it is not much popular investment model to infrastructure development at the moment. Further the
government should change their role from developer and operator to facilitator to improve the PPP practice in
Sri Lanka
PPP Bankable Feasibility Study: A Case of Road Infrastructure Development in ...inventionjournals
Adequate and reliable bankable project feasibility study according to Adamuet al. (2015) determines the private sectors investment interest in a PPP transaction which centers around project demand forecast taking into account the willingness to pay, inter and intra-model competition, ramp-up effects, and long-term macro-economic effect and population growth rate. In order to achieve this, WEF (2013) noted that public sector needs to determine the project technical specifications, and also carry out a detail cost benefit analysis so as to determine the project’s commercial viability to be followed by proactive and professionalized stakeholder engagement. Efforts must also be made to mitigate the social and environmental impact of the proposed infrastructure. This is very essential in determining the bankability of any infrastructure development. This study is aimed at assessing the effectiveness of bankable feasibility study and factors affecting bankability of road infrastructure development under PPP concession. In order to achieve this aim, the study examined the concept of PPP models for infrastructure development and bankable feasibility process in a PPP framework. Data collection was through administration of well-structured questionnaire on the target population. Data collected were analysed using both descriptive and inferential statistic analytical techniques. The study revealed that there is urgent need to review the current Nigeria National Policy on PPP, institutional structure and individual capacity building in the area of PPP project preparation in order to encourage more private sector participation in the drive for provision and development of road infrastructure facility.

This is a survey that investigates the awarenessof professionals and other participants in the Nigerian construction industry in the use of public private partnership and its variant methods in procuring infrastructure in Nigeria.The paper assesses the variants of PPP in infrastructure development, identifies the issues and benefits associated with PPP and factors that affect the choice of the variants. The study employs structured questionnaire to gather pertinent data from the consulting firms of practicing professionals and other practitioners in the built environment in Nigeria such as; 1. Quantity Surveyors; 2. Architects; 3. Engineers; 4. Builders. 5. Land Surveyors; 6. Lawyers. Thereafter, stratified random and purposive sampling technique was used in the selection of respondents to the survey questionnaire. Result shows that Nigeria began to use PPP for project procurement in the mid to late 1990s and the trend is expected to continue into the future, with positive impact on the private and public sectors. The study also, finds that BOT a variant of PPP is the most commonly used with a mean weighted value of 6.78 or 68%; ranked first with 28.4% of respondents. Followed by SC with 23.9%; MC with 19.4%; CC with 13.9%; JVP with 10.5% and PFI with 4.5 respectively. This survey concludes that government should partner more with the private investors in the provision of infrastructure in the face of dwindling resources of government; it also recommends that; 1. PPP and its variants should be popularized through organized workshops and seminars; 2. Its advantages should be propagated to attract local and foreign investors; 3. PPP and its variants should be used to mitigate the challenges facing the traditional method of procurement of infrastructures

Stakeholder analysis is component in a project design and implementation central to achievement of the goals and objectives for which projects are carried out. This study aimed at establishing the effect of stakeholder analysis on performance of road construction projects in Elgeyo Marakwet County. The study was anchored on Stakeholder Theory. The study population comprised of 19338 individuals who included employees of the county working within the road sector, personnel within various road construction agencies, contractors and community beneficiaries of the project. Stratified random sampling was then used to group individuals into two homogenous groups, one working directly with the project and the other of beneficiaries. Proportionate random sampling technique was then employed to sample 103 respondents in the first group who included Managers (4), County government employees (29), KURA (6), KenHA (6), KERRA (13) and Contractors (45). Simple random sampling was adopted to select 377 respondents from the community. Data collection instruments were self-administered questionnaires for personnel working directly with the project. On the other hand research assistants facilitated focused group discussions to get views from the community stakeholders. Both descriptive and inferential statistics informed the data analysis and presentation. Descriptive statistics included; percentages, means, standard and deviation. Inferential statistics was Analysis of Variance (ANOVA) and multiple ordinal regression equation analysis. Statistical package for Social Sciences (SPSS 23.0) software helped in data analysis. The study found out that stakeholder analysis had significant effect on performance of road construction projects (β3=0.203, P <0.05) on performance of road construction projects in Elgeyo Marakwet. The study recommends county Government should develop blueprints to guide road contractors in road project activities. Hence establish a favourable environment for implementations of road projects.

Quantity Surveyor’s Impact: A Panacea to achieving Critical Success Factors i...inventionjournals
Public-Private-Partnership (PPP) is an innovative infrastructure procurement system aimed at providing unique opportunities in the development and funding of public infrastructure facilities.The procurement system ranges from simple contracting of services to the involvement of private sector in financing, design, construction, operation and maintenance of infrastructure. However, organising PPP is not an easy task due to its complexity and long term contractual obligagtions that requires the involvement of stakeholders and professionals for its successful implementation. Procurement procedure under PPP is very complicated and more costly and time consuming than the traditional procurement approach. Therefore the need to address the roles of the Quantity Surveyor in providing the total cost and procurement management has been recognized and become necessary in developing effiecient and effective sustainable PPP projects. Although many studies show that there has been no comprehensive study on the roles of the Quantity Surveyor in PPP concession projects which therefore indicate a knowledge gap in this particular area of the study. Hence, the aim of this paper is to explore the roles of professional Quantity Surveyor in achieving the critical success factors (CSF)for PPPconcession projects. Findings in the study have shown that Quantity Surveyor has a great role to play in achieving the Critical Success Factors (CSF) for PPP concession projects in the areas of:detailed feasibility study; compititive financial proposal; effective procurement management; preliminary qualification evaluation & tendering phase; solid revenue & cost estimate; proper partner’s selection criteria; and solid financial packaging. Findings from the study further revealed that the PPP contractual arrangement offers the primary role of a professional Quantity Surveyor within the PPP concept leading to the selection of the right concessionaire through: request for expression of interest, qualifications, proposals; negotiation with preferred bidders; and evaluation methods & criteria and also in the performance evaluation of the entire development and delivery process within the project objectives.

Causes of delay in indian transportation infrastructure projectseSAT Journals
Abstract A survey on time performance of different types of construction projects in western Maharashtra was conducted to determine the causes of delay and their importance according to each of the project participants, i.e., the owner, consultant and the contractor. Sixty four causes of delay were identified during the research. It seems that the problem is common and notable as 72% of the total infrastructure projects reported by all the respondents were delivered late, whereas only 28% were completed on time. Clients’ respondents indicated that 59% of the public projects they were involved in were delivered late. Consultants’ respondents reported that 62% of the projects they were involved in were completed late. Contractors’ respondents also share the same view and articulated that 77% of the projects they are involved in exceeded the preset duration. The top five important causes of construction delays in transportation infrastructure projects are mainly Land Acquisition, Environmental Impact of the project, financial closure, Change orders by the client, Poor site management and supervision by contractor .Respondent’s opinion about the contribution towards the delay is 50 % respondent feels that delay in the construction in mainly due to the contractor. 40 % of respondent feel that client is mainly responsible for the delay in construction projects. And only 10 % of respondent feel that delay mainly occur due to consultant. It is evident that consultant as a mediator has less responsibility in construction delays. Keywords: Transportation infrastructure projects; Construction delays; Questionnaire survey; Relative importance index.

Quantity Surveyor’s Impact: A Panacea to achieving Critical Success Factors i...inventionjournals
Public-Private-Partnership (PPP) is an innovative infrastructure procurement system aimed at providing unique opportunities in the development and funding of public infrastructure facilities.The procurement system ranges from simple contracting of services to the involvement of private sector in financing, design, construction, operation and maintenance of infrastructure. However, organising PPP is not an easy task due to its complexity and long term contractual obligagtions that requires the involvement of stakeholders and professionals for its successful implementation. Procurement procedure under PPP is very complicated and more costly and time consuming than the traditional procurement approach. Therefore the need to address the roles of the Quantity Surveyor in providing the total cost and procurement management has been recognized and become necessary in developing effiecient and effective sustainable PPP projects. Although many studies show that there has been no comprehensive study on the roles of the Quantity Surveyor in PPP concession projects which therefore indicate a knowledge gap in this particular area of the study. Hence, the aim of this paper is to explore the roles of professional Quantity Surveyor in achieving the critical success factors (CSF)for PPPconcession projects. Findings in the study have shown that Quantity Surveyor has a great role to play in achieving the Critical Success Factors (CSF) for PPP concession projects in the areas of:detailed feasibility study; compititive financial proposal; effective procurement management; preliminary qualification evaluation & tendering phase; solid revenue & cost estimate; proper partner’s selection criteria; and solid financial packaging. Findings from the study further revealed that the PPP contractual arrangement offers the primary role of a professional Quantity Surveyor within the PPP concept leading to the selection of the right concessionaire through: request for expression of interest, qualifications, proposals; negotiation with preferred bidders; and evaluation methods & criteria and also in the performance evaluation of the entire development and delivery process within the project objectives.

Causes of delay in indian transportation infrastructure projectseSAT Journals
Abstract A survey on time performance of different types of construction projects in western Maharashtra was conducted to determine the causes of delay and their importance according to each of the project participants, i.e., the owner, consultant and the contractor. Sixty four causes of delay were identified during the research. It seems that the problem is common and notable as 72% of the total infrastructure projects reported by all the respondents were delivered late, whereas only 28% were completed on time. Clients’ respondents indicated that 59% of the public projects they were involved in were delivered late. Consultants’ respondents reported that 62% of the projects they were involved in were completed late. Contractors’ respondents also share the same view and articulated that 77% of the projects they are involved in exceeded the preset duration. The top five important causes of construction delays in transportation infrastructure projects are mainly Land Acquisition, Environmental Impact of the project, financial closure, Change orders by the client, Poor site management and supervision by contractor .Respondent’s opinion about the contribution towards the delay is 50 % respondent feels that delay in the construction in mainly due to the contractor. 40 % of respondent feel that client is mainly responsible for the delay in construction projects. And only 10 % of respondent feel that delay mainly occur due to consultant. It is evident that consultant as a mediator has less responsibility in construction delays. Keywords: Transportation infrastructure projects; Construction delays; Questionnaire survey; Relative importance index.

Anti-Smog Radar Application for VehiclesIJMREMJournal
Smog is regarded as a dangerous situation for vehicles as the visibility of human fails and a person cannot
drive smoothly and safely which can lead to severe accidents and routine disturbances. Hence, “Anti-Smog
Radar Application for Vehicles” is proposed using Internet of Things technology which ensures the smooth flow
of vehicles in smog and prevents accidents in time and cost-efficient manner by detecting and displaying the
front objects with their important information (distance, position, velocity and size) on smart phone used by
authenticated drivers. The radar application controls the hardware system to be deployed on vehicles through
which the user can start, stop and set the hardware in particular direction. The hardware contains NodeMcu
(Microcontroller with built-in Wi-Fi), Ultrasonic sensor and servo motor. The servo is used to detect the
position of front objects and ultrasonic sensor is clipped on servo to detect the objects. For alerts, the objects
are drawn with different colors on application i.e. the red colored objects will be near to the vehicle, the yellow
colored objects will be at some distance from the vehicle and the green colored objects will be far from the
vehicle. Kalman algorithm is used to filter the ultrasonic readings to eliminate the noise. The proposed system
can work in every condition i.e. in day and night.

Reactivity Feedback Effect on the Reactor Behaviour during SBLOCA in a 4-loop...IJMREMJournal
The reactivity coefficient is a very important parameter for safety and Stability of reactors operation. To provide
the safety analysis of the reactor, the calculation of changes in reactivity caused by temperature is necessary
because it is related to the reactor operation. The objective is to study the effect of the temperature reactivity
coefficients of fuel and moderator of the PWR core, as well as the moderator density and boron concentration on
fluid density, reactivity, void fraction. peak fuel clad temperature and time to core uncover were found for two
feedback cases. This paper focuses on the effect of the Reactivity feedback, of the 6" (6-inch) Cold Leg
SBLOCA sequences in a 4-loop PWR Westinghouse nuclear power plant with a scram for various feedback,
moderator density coefficient, MDC, moderator temperature coefficient, MTC, the fuel temperature coefficient,
FTC, and boron concentrations. Dragon neutronic code is used for calculating reactivity's coefficient which is
used in RELAP5 thermal hydraulic computer code to simulate the effect of Reactivity feedback during Cold
Leg SBLOCA. The plant nodalization consists of two loops; the first one represents the broken loop and the
second one represents the other three intact loops. In the present analysis two models in RELAP5 code for
computation of the reactivity feedback, separable and tabular models are used. The 6-inch break size was chosen
because the previous work [1], showed that it was the worst size break in a 4-loop PWR Westinghouse. The
results show that the neglecting of the reactivity feed-back effect causes overheating of the clad and that the
importance of the reactivity feed-back on calculating the power (reactivity) which the key parameter that
controls the clad and fuel temperatures to maintain them below their melting point and therefore prevent core
uncover and fuel damage where the fuel temperature, clad temperature and core water level are in the range.

Energy Conservation through Smart Building and Smart Lighting SystemIJMREMJournal
Energy conservation is an extensive topic due to the propagation of electricity demand and challenges globally
and is regarded as one of the most significant issues affects the power system quality, global environment and
consumers. Smart building is a technology that can connect everything to networks or systems to monitor and
control them in various areas such as offices, energy-consuming devices especially in laboratories, security
devices etc. Nevertheless, people's perception about using smart technology for energy saving is still in the mind’s
eye. This means that people discuss about environmental awareness readily. Due to the availability of electricity
and its elemental role, regulating consumers’ behaviours towards power savings can be a challenge. Remarkably,
the gap in today's smart technology design in smart buildings is the compassionate of consumers’ attitudes and
the merging of this perspective into the smart technology. Implementation of PLC based controlling system is a
convenient method to save the power and energy strategy for whole building. Furthermore, prepare a lighting
scheme can results a rapid response in energy conservation. Consequently, PLC Automatic system removes the
human intervention which makes the process smart and energy reduction will gives benefits to the consumers in
terms of reducing the cost of electricity bills. Nonetheless, contemporary buildings’ energy conservation has been
significant solution to cope with the rising electricity necessity.

Predicting Trade Conflict Outcomes using a Third-Party Intervention ModelIJMREMJournal
As anti-import sentiment and protectionism have been increasing, more papers have focused on using theories to explain or resolve them. However, most research has focused on disputes involving larger nations such that there is not much relatable information for disputes such as the one between South Africa and Zimbabwe. The aim of this paper was to bridge the knowledge gap by using the graph model for conflict resolution and the decision support software GMCRII to simulate possible responses to this regional trade conflict. This thirdparty intervention model will assist in investigating and prescribing a diplomatic solution with fair compromise to resolve the unequal trade problem between Zimbabwe and South Africa without harming the economies of both the countries. This research found that a peaceful resolution of the disagreement could be found by the addition of a third-party to help in the conflict resolution thereby ending the prolonged trade conflict. This undertaking will serve as a template for modelling and predicting an outcome in the event of third-party intervention for future trade disputes involving regional trade partners with emerging or developing economies such as those that exist in Africa

Road networks ought to be efficiently designed to be safe, speedy and loading sustaining as it has a significant importance in country’s development. For that, pavement should be designed efficiently to exhibit better strength, durability and economical at the same time. Generally, a pavement is classified as Flexible or Rigid. Flexible pavement is opened early to traffic, has good riding quality and ease of maintenance but owing to heavy loading conditions these pavements are more susceptible to wear and tear. On the contrary rigid pavement is load sustaining, durable but having higher construction cost and poor riding quality. World is heading to semirigid pavement which exhibits characteristics of both these pavements. It is the combination of cement concrete and porous asphalt concrete which is achieved by leaving 25% to 30% air voids infused by cement grouts and is known as Semi-rigid pavement.In this research, semi-rigid pavement was designed using ratio of grout of optimum mix was 1:0.55 at water cement ratio by 2% of cement dosage with SP. Study concludes that, Semirigid pavement’s Marshall stability of 7 days was almost 85% of rigid pavement and 28 days compressive strength of semi-rigid pavement was almost 30.5% that of rigid pavement. Besides, it has been ensured that 7 days strength is comparable to 28 days strength of Semi-rigid pavement.

In this research study, a cold recycled mixture is designed and compared in terms of mechanical and volumetric properties with control hot mix asphalt mixture, using 60% RAP (reclaimed asphalt pavement) aggregates and 40 % virgin aggregates to fulfill gradation requirements. Asphalt emulsion for cold recycled mixtures is used as a binder with varying five contents (4.3%, 4.8%, 5.3%, 5.8% and 6.3%). Also, a modified cold recycled mixture is prepared at optimum emulsion content of control cold recycled mixture by partially replacing conventional aggregate mineral filler with three different contents of Portland cement (2%, 3% and 4%) of total dry mass of aggregates. Marshall mix design procedure was adopted to calculate the optimum (bitumen, emulsion and filler content) for control hot mix asphalt, control cold recycled mixture and modified cold recycled mixtures respectively. Mechanical properties of each of these mixtures were compared with each other and it was found that modified cold recycled mixtures were better than controlled cold recycled mixture and comparable in properties to hot mix asphalt mixtures and Optimum filler content of Portland cement for modified cold recycled mixture was found to be at 4%.
Thermodynamic Analysis of Cooling Tower with Air to Air Heat Exchanger for Re...IJMREMJournal
In this paper a thermodynamic analysis of cooling tower with air-to-air heat exchanger is presented. During manual operation of conventional cooling tower, a good quantity of water is evaporated which requires equivalent amount of makeup water for their condensers. So, in this regard, the thermodynamic model of a cooling with an air to air heat exchanger is developed using engineering equation solver (EES) software and then simulated in different climatic conditions of two major cities of Pakistan namely Karachi and Jamshoro through the period of June & December 2017. The results show a significant variation in water vapor recovery with respect to atmospheric conditions mainly humidity and ambient air temperature. Results reveal that the when a cooling tower coupled with air to air heat exchanger maximum amount of water vapors are recovered at Karachi and ranges up to 67% and 62% in Jamshoro during the month of December.
Modeling and Development of Pneumatic Accumulating SystemIJMREMJournal
This document summarizes a study on developing a pneumatic accumulating system to harness wasted energy from moving vehicles. The system uses a spring-loaded piston cylinder underneath the road to convert a vehicle's weight into air pressure energy. This pressure energy is then sent to accumulation tanks through check valves for storage. A mathematical model is developed to simulate the system and calculate the pressure generated in the cylinder and accumulated in tanks. Simulation results in MATLAB show the system can accumulate over 4 bars of pressure from a 1000kg load, increasing with additional loads. The study concludes the proposed system is an effective way to extract wasted vehicle energy for useful purposes like powering gas stations or wind turbines.

----------------------------------------------------ABSTRACT ------------------------------------------------------
Significant infrastructure such as roads, prisons, schools, rail tracks and train systems, among others are currently
developed through the involvement of Public Private Partnership (PPP) arrangements which have been
acknowledged internationally in recent time. The poor management of end-user stakeholder during PPP projects
in developing nation like Nigeria has been established as one of the major factor affecting the successful growth
and development of PPP projects. Due to the paucity in research on end-user stakeholder management on PPP
projects in Nigeria, informs this study aim to expose the main strategic factors that can accommodate end-user
stakeholder’s management in any PPP road project in Nigeria. The professionals that have worked on the project
cum the end-user of the project area were used as targeted respondents for the adopted case study and survey
strategies method approach. Thematic analysis was used to analyse the eighteen (18) interviews that were
conducted having completed and analysed total number of 282 questionnaires using reliability and factor analysis
approach. Seven valid underlying factors were revealed from 28 variables that were left on the questionnaire data
with the aid of factor analysis which were used later as factors affecting end-user stakeholders’ management in
PPP road project in Nigeria. A proposed framework was created with the seven underlying factors as a template
for any successful PPP road project in developing country like Nigeria. These will quench the agitation of end-
user stakeholders’ quarrels on PPP toll road projects.

I. INTRODUCTION
The regulatory capabilities and supervisory of public and private sector in terms of infrastructure approach through
Public Private Partnership PPP expected to deliver facilities for end-user stakeholders of road project through the
finance and effective managerial expertise (Li et al., 2011; Oyedele, 2012). Developing nations such as Nigeria
are struggling with meeting rapidly expanding infrastructure needs while revenues continue to decline. One of the
options needed to survive the monumental catastrophe is to embrace PPP as a way of cushioning the effect of
those challenges (Ibem, 2011; Kennedy et al., 2015). The poor management of end-user and stakeholder in Nigeria
and some part of the world bemoan the challenges affecting the successful growth and development of PPP
(Amadi et al., 2014; Abednego and Ogunlana, 2006). PPP has becomes an alternative project delivery options
which are in quest from various government agencies with the inclusion of private sector financing to help in
meeting these prerequisites. For any successful PPP projects the inclusion of end-user stakeholders are very
important (Olander, 2007). The disenchantment of any project can occur if issues concerning end-user
stakeholders were failed to be addressed (El-Gohary et al., 2006; Majamaa et al., 2008).
The effects of infrastructure project on end-user stakeholders are not only for short or medium periods but also
long period; the overall success of infrastructure project is to ensure community benefits are delivered over the
lifecycle of any project (Kumaraswamy et al., 2007). Meeting the desired objectives of end-user stakeholders
presently without involving the future generations is a colossal waste of time and energy (World Commission on
Environment and Development, 1987). The poor management of end-users stakeholders’ interests mostly in
Nigeria and Africa PPP projects is undervalued (Ncube, 2010). End-user stakeholders are the most forgotten
customers of PPP projects in the construction industry (Lehtiranta, 2015).

According to Gregory et al. (2003), opposition with end-user stakeholder mostly emerge in projects where the
public sector adopts a ‘user-pays’ PPP approach. The entire cost of the project will be transferred to the end-users
(mostly private and commercial motorists) when using user-pays model for PPP road projects. Predictably, such
decisions result in stiff resistance and public outcry (Yuan et al., 2009). Other issues such as compensation
packages, traffic congestion among others often raise enormous tension concerning PPP road projects whether in
Nigeria or any other part of the world (Amadi et al., 2014; Cheung et al., 2010; Gupta and Agrawal, 2013).
Stakeholders’ opposition is a global phenomenon and remains the key reason behind the failure of many PPP
initiatives (Banaitienė et al., 2011; Yuan, et al., 2009). Some earlier studies have observed and identified a number
of factors and measures for managing every end-user stakeholders in PPP projects arena (Amadi and Tuuli, 2014;
Chung et al., 2010; Eskerod and Jepsen, 2013; Freeman, 2010; Awodele et al., 2011; Mok et al., 2015; Smyth,
2008). This study follow suit by observing and identifying the most important features required for effective
management of end-users stakeholders of PPP road projects in Nigeria.
Accordingly, the aim of this study is to expose the main strategic factors that can accommodate end-user
stakeholder’s management in any PPP road project in Nigeria. The objectives are
1. To identify factors that is affecting the management of end-user stakeholders through a qualitative and
quantitative procedure.
2. To develop a framework for managing end-users stakeholders PPP performance in Nigeria.
This study will contribute to knowledge by providing new directions into understanding of end users stakeholders’
interests in PPP road projects in Nigeria and other developing countries. It can also contribute by showing
guidelines to be followed when implementing PPP in the entire construction industry. The scope of this work is
limited to the two PPP toll road projects that are constructed within the last 10 years by private investors before
the intervention of State and Federal governments of Nigeria. The toll roads are situated in Lekki and Ikeja axis
of Lagos State within the borders of Nigeria. The toll road projects are used by both private and commercial users
which is not a barrier for adoption as sample. All end users that are considered are all toll-paying users which
include commercial buses, commercial cyclist, commercial taxis, commercial Lorries, trucks or trailer, private
bikes, private cars, private buses, office workers and pedestrians among others.
Literature review and methodology will be described concurrently in the subsequent section. The methodology
will engage mixed method strategy which combines both qualitative and quantitative methods before describing
the questionnaire methods for both factor types. The section of analysing data will then follow where questionnaire
surveys were developed through observed conducted interviews. The analysis of results follows with the section
of discussion and proposed framework respectively. The study is rounded up with concluding section.
II. LITERATURE REVIEW
Public infrastructures is necessary in any functional society which could thrive an economy that lacked services
and facilities required by end-user stakeholders of a community, city, and nation (Torrisi, 2009). Economic and
Social infrastructure are considered as classification of infrastructure which are important for daily transportation
facilities such as road, rail, electricity, sewage and sewage among others and also societal facilities such as
hospitals, post office, prisons, libraries, schools among others. Developments remained an unending challenge in
emerging economy like Nigeria in terms of road construction and maintenance of public infrastructure facilities
(Zawawi et al., 2014). In developing key infrastructure projects it is increasingly important that the concepts,
applicability, pros and cons of PPP must be established. Developing countries around the globe have adopted
various ways of financing public infrastructures which always required huge capital, in which Nigeria is not
exclusive (Ibrahim et al., 2009). Financing of projects is one of the oldest methods of alleviating burdens of
infrastructure facilities before the advent of PPP during the ancient Roman and Greek era, where repayments of
goods and loans was structured through trade by barter with equal risk sharing (Brewer et al., 2013). According
to Yescombe (2011. p1) Project finance can be defined as:
“A method of raising long term debt financing for major Projects through financial engineering, based on lending
against the cash flow generated by projects alone, it depends on detailed evaluation of project construction,
operation and revenue risks, and their allocation between investors, lenders and other parties through contractual
and other arrangements.”
The underlying principle in project finance is equitable risk sharing where financial arrangements are non-
recourse. Until recently,

when the arrangement scheme of PPP now becomes one of the most prolific applications of project finance with
less burden of risk sharing (Gangwar and Raghuram, 2015). The delivery of public amenities through PPP became
more robust in economic development of any developing nation (Crozet, 2014).
In 1992, United Kingdom (UK) introduced PPP as an upgraded version to Private Finance Initiatives (PFI)
(Oyedele, 2012). The two are almost the same in terms of procedure but slightly different in procurement
application for public use, as well as well as perceived inefficiencies in the public sector (Brewer et al., 2013;
Oyedele, 2012). Public infrastructure development had become a major challenge for many governments across
all levels throughout the globe in the last two decades (Ibrahim et al., 2009). Nigeria amongst other developing
countries were facing rising public sector debt due to the increasing pressures on both existing and future
infrastructures facilities (Babatunde et al., 2016). Provision of numerous public amenities was initiated by the UK
Government through PFI by engaging private management expertise (Loosemore and Cheung, 2015). With the
emergence of PFI framework, public utilities such as construction/engineering services, health care services, mail
services, waste management, street cleaning, housing and prisons services among others were delivered
successfully in the UK (Brewer et al., 2013). Infrastructures estimated at over £70 billion have been delivered
successfully through the PFI/PPP approach (Oyedele, 2012).
History has shown that Nigeria has not fully engaged in the infrastructure development through either PFI or PPP
which was buttressed by the report of World Bank indicating that the government only spends equivalent of 1%
of her gross domestic product (GDP) on critical infrastructures (Kennedy et al., 2015; Babatunde et al., 2012).
The global economic slowdown had also contributed to the reform through the rising costs of construction
materials in developing the infrastructure projects. In the advent of this, the Federal government of Nigeria set up
Infrastructure Concession Regulatory Commission (ICRC) and mandated the agency to regulate and publicised
any moribund PPP projects (Babatunde et al., 2016). Relevant Ministries, Departments and Agencies (MDA) were
co-opted in actualizing the ill-fated attitude of government officials who are grossly embedded with corruption.
All key elements of the development of these projects were considered including the procurement models in terms
of financial, legal and technical distinctions. Performance requirements, risk evaluation, legislative contracting
allowances and assignment were not left out (Babatunde et al., 2016). Some of the abandoned PPP projects that
were considered for completion by the current administration were listed below.

Some of the motives that inspired the federal government to embark on the abandoned PPP projects are the
reviewed recommendation of the Infrastructure Concession Regulatory Commission (ICRC, 2013)
institutionalising infrastructural growth and service in order to rally round the following (a) To reform all sectors
and improve accountability through reallocation of incentives and roles (b) Optimal utilization of available
resources (c) To increase the organisational policies and plans that will lay concrete foundation for valuation and
transparency and (d) To entice more skilled force with economic talent and orientation on effective performance.
5. Proposed Framework for Effective Management of End-User…

The initial design of PPP guidelines, legislation, policies through the ICRC did not consider the role of end-user
stakeholders in construction project but distributes particular roles and responsibility to several bodies. These
bodies and federal government are considered in their plan without the participation of end-user stakeholders. The
ICRC framework unlocks opportunities and creates potential benefits for private investors and the government
(Akintoye et al., 2011), but forgot the inclusion of the direct beneficiary of those infrastructure facilities who are
end-user stakeholders. Lagos state took an opportunity of the framework in continuing the PPP arrangement that
was initiated and passed into law by the Lagos State Roads, Bridges, and Highway Infrastructure Development
Board (2004). The state government later supplemented infrastructure law with other procurement laws and
considered it as the Lagos State Public Procurement Law 2011. The law provided a framework in replica with
ICRC guideline in recognition for only private sector in the delivery of public infrastructures. This does not
include the interests of end-user stakeholders who are the beneficiaries of the infrastructure facilities. Find below
the organogram institutionalizing PPP framework which was re-enacted in the year 2012 by ICRC.

III. RESEARCH METHODOLOGY
A genuine approach to research is for a researcher to have freedom in choosing any convenient methods,
procedures and techniques that is suitable for the purpose of the study (Teddie and Tashakkori, 2012). A mixed
method approach consisting of both in-depth interviews and questionnaire survey to end user stakeholders for the
prescribed PPP road Projects in Nigeria was adopted for this study. Also an exploratory sequential mixed method
approach was engaged for data collection and analysis. This is considered in order to improve the validity and
generalizability of the qualitative findings (Feilzer, 2010). Both professionals and end-user stakeholders that have
worked and lived in the project community informed the in-depth interview. These elicit the subjective views of
the participants along the neighbourhood of the projects. Case study strategy was used to formulate questionnaire
which were later sent to the wider audiences of end-user stakeholders of the projects in Lagos Nigeria
Qualitative data collection : Qualitative data are characterised by its fullness and richness established on the
prospect of reality of subject exploration (Saunders et al., 2012). It is used to expose tendencies in opinions and

thought, and plunge deeper into the root of the problem. The outcomes of findings for qualitative proceeding are
mostly words count instead of numbers as in quantitative research. As part of reference point for this study,
literatures that were reviewed previously dealt with quantitative method of approach without the consideration of
qualitative aspect of it. The qualitative data for this study is used as a tool for robust strength on end-users’
stakeholders’ participation in PPP toll road project which will narrow the agitation between governments, private
investors and end-user stakeholders of the host communities (Green et al., 2007).
Professionals that have worked on the PPP toll road for this study were interviewed with the end-users
stakeholders of the host community. The professionals are project engineers, design managers, project managers,
field engineers, consultant and senior manager while the end-user stakeholders are the direct beneficiary of the
project. These are members of project’s host communities, commercial transports road users, office employee
within project locations, private road users and other commuters (see Table 1)

Pilot survey was carried out considering three professionals that have worked on the PPP toll road project. Two
of the three professionals are from the first case study while the other is from the second case study respectively.
Snow balling sampling method was used to recruit two of the three professionals that were considered for both
case studies. These are the people that have the background knowledge of what has happened before, during and
after the emergence of the projects. Finally, ten (10) facilitators were trained on how to conduct and record
interviews in accordance with ethical compliance standard for nine weeks and eighteen (18) interviews were
conducted from both Project Organisation/Company staffs and direct end-users of PPP toll road projects.
Purposive sampling method was adopted to identify information-rich participants among the experienced staff of
the PPP road concessionaires (Special Purpose Vehicles), while snow balling sampling approach was used to elicit
qualitative findings from direct end-users of the identified PPP road projects. These include project engineers,
design managers, projects managers, field engineers, consultants, and other project team members with minimum
of 5 years of involvement with the PPP road projects and end users of the PPP road projects including members
of projects’ host communities, commercial transporters i.e. drivers, passengers, and other private road users
(personal cars, trucks etc.) that have spent the same numbers of years in the project area.
Unstructured interview method was adopted for this study due to its flexibility, informal, free flowing and open-
ended way of asking questions. Digital recorder was used to record the interviews and later transcribed for analysis
and also translated verbatim in English with the use of Microsoft Word. The Nvivo software word rate of
7. Proposed Framework for Effective Management of End-User…

recurrence search was also used to construct themes. As such, the information was carried out through coding
skill, which certifies that only significant connotations originated from the information are considered (Braun and
Clarke, 2013). All issues discovered during interpretation through the interview transcripts were used to create
conceptual categories which was regarded as major themes. Examples of coding of themes and the ‘respondents’
statements were taken as it was presented in Table 2 while the resultant themes and sub-themes are afterwards
used as variables in the questionnaire (quantitative) used in this study, as presented in same Table.
Quantitative data collection: The predominant purpose of a quantitative research study is to categorize features,
sum total them and build statistical models in an attempt to describe any observation (Amaratunga et al., 2002).
This section exhibited the performance, analysis and interpretation of data collected from the end-user’s
stakeholders’ of Lekki-Epe and Apakun PPP road project in Lagos State Nigeria through a designed questionnaire.
The survey strategy was executed with questionnaire data collection which was developed from the interview data
processing. Similarly, in order for research data to be valuable and usable, they must be reliable in terms of
measurement stability or consistency in research findings repeatedly (Sahner et al., 2012). An introductory
questionnaire was initially developed for pilot survey from resulting themes in order to determine the relevancy
of each identified variables in PPP road project. This was used in appraising the significance/accuracy, length,
layout and intricacy before it was finally sent out for broader set of targeted respondents.
The final study was carried out with the assistance of fifteen (15) volunteer respondents from the two locations
respectively. Thirty-three (33) questions were finally developed from the entire interviews with the use of Nvivo
software after the major feedback from the volunteer respondents. A five-point Likert scale rating was used to
evaluate the significance of various identified factors that can ensure better management of end-user stakeholder
in Nigeria’s PPP toll road projects with 1 representing “No Effect” and 5, as “Best Option”. A total number of
400 questionnaires were targeted for the respondents on both case studies. Three hundred (300) questionnaires
were shared among Lekki respondents while one hundred (100) questionnaires were shared among ikeja
respondents respectively. Numbers of tolling points informed the sharing ratio for the exercise. Two hundred and
eighty-two (282) questionnaires were returned from both locations representing approximately 70.5% return rate.
The respondents from Lekki-Epe toll road returned 252 filled questionnaires while respondents from Apakun
Muritala Muhammed toll road returned 30 filled questionnaires. The entire 282 questionnaire were usable for the
analysis. The returned rate was impressing from the Lekki-Epe respondents because of their concerned effort on
how they have been marginalized before, during and after the project while the responses from Apakun Murtala
Muhammed respondents were disappointing because of their lackadaisical approach to salient issues affecting the
road users. The questionnaire data was analysed using Statistical Package for Social Sciences (SPSS) software.
IV. DATA ANALYSIS AND FINDINGS
This section educates more on the established feedback that was gathered through interview and questionnaires
showing understanding and experience from diverse people of different taught (Atkinson, 2014). With these, data
and information on the analysis which gives the skills and in-depth knowledge related to qualitative and
quantitative data collection processes were analysed (Driessnack and Furukawa, 2012). Questionnaire surveys
were developed through observed conducted interviews.
Qualitative Data Analyses : Several numbers of approaches can be used to analyse qualitative data, each
approach stemming from different traditions (Saunders et al., 2012). In this study, themes are identified as
measures that could be put in place to strengthen the end-user stakeholders’ complaints on marginalization in their
respective needs. This is done with the use of thematic analysis in identifying both implicit and explicit
declarations that originated from the transcribed data (Braun and Clarke, 2013). The analysis understands
numerous features of the research theme (Boyatzis; 1998). In order to satisfy the objectives of this study, issues
raised by the respondents in terms of conflicts of interest on the PPP toll roads are explored and a thematic analysis
was carried out with the aid of Nvivo software (Green et al., 2007). Non-experimental, exploratory and
unstructured qualitative primary data segments were considered. Re-occurrence of words in relation to potential
factors affecting the end-user stakeholders along the neighbourhood of the project was noted and coded. Each
factor was categorised under a major category according to findings. The frequency was shown according to the
analysis at which each factor was mentioned and also indicating the environment in which it was mentioned
among others. Coding examples of themes from the respondent’s statements were presented in Table 2.

This area is worse during raining season with

Look at what happened during recent rainfall
with continuous massive flooding which took
the state government over 24hours to
respond to peoples call after their properties
have been destroyed by water due to heavy
downpour.
I think the government should do all the

Researcher has to read and re-read each line of text to understand the meaning that influences each line before
coding at the appropriate nodes or deciding the themes suitable for the text. Extra effort was made to maintain
awareness on the effect of research process based on the desirable factors affecting end-users stakeholders during
the analysis and interpretation of obtained data. It is notably recognised that many components of the research
process such as respondent’s command of interview/story language (i.e. English language), talkative ability, social
class, level of experience among others may have had effect on the eventual output. Most of the findings are taken
as building process between the researchers and the respondents, representing the reality of marginalisation of
end-user stakeholders of PPP road projects. Indeed, the procurement of qualitative data had supported the
quantitative inputs of this study; hence, strengthened the overall findings of the study. These are presented in
Table 3
V. QUANTITATIVE DATA ANALYSIS
Reliability analysis: The presentation and analysis of results was done based on the data assessed for the
reliability for the required statistical tests by checking the cronbach alpha of the data set and also a test KMO and
Bartlett tests for appropriateness of using Factor analysis. This data was analysed for evaluating the end users and
stakeholders needs for the purpose of achieving objectives of the study. As recommended by many social scientists
(Field, 2009; George and Mallery, 2003; Nunnally and Bernstein, 1994; Spector, 1992; among others), Cronbach’s
alpha coefficient is used in this study to test and examine the reliability of the questionnaire data. Mathematically,
Cronbach’s alpha is written as
α = N2
COV .
∑S2
criteria + ∑COVcriteria
The main objective of the test was to checked the constancy of the obtained data in order to found if the variables
and their associated Likert scale are really assessing the concept they were envisioned to measure (Field 2009).
The concept, in this case, is the title given to each numbers of variables as related to the management of end-users
stakeholders in Lekki- Epe toll road. The coefficient of Cronbach's alpha value ranges from 0 to 1 and as a thumb
rule, 0.9 and above represent high consistency, but 0.8 was described as a sign of good internal consistency
(reliability) while 0.7 is recommended as the lowest acceptable score (George and Mallery 2003). Table 3 presents
the Cronbach’s alpha coefficient test results gotten from SPSS. The reliability test was ran and the overall
Cronbach’s alpha coefficient gotten was 0.882, depicting good internal consistency of the data.

To check if all the variables are contributing to the internal consistency of the data, the ‘Cronbach's alpha if item
deleted’, positioned in column three of Table 3 is further examined. To check if all the variables are contributing
to the internal consistency of the data, the ‘Cronbach's alpha if item deleted’, positioned in column three of Table
3 is further examined. A variable that is not contributing to the overall reliability from the sets of variables will
generally have a higher correlated ‘Cronbach’s alpha if item deleted’ value than the data’s overall Cronbach’s
alpha coefficient (Field 2009). This higher value represents that if the variable with the value is deleted, the overall
reliability of the data will increase (Field 2009). In this context, only variables with serial number 3, 10, 13, 21,
and 28 respectively that are boldly written in italics with peach colour in Table 3 has a ‘Cronbach’s alpha if item
deleted’ value which is greater than the overall coefficient (0.882). This implies that these criteria with serial
number 3, 10, 13, 21, and 28 are relatively not a very good measure of the concept hence they were not considered.
Factor Analysis: There is need to establish the main underlying factors that form the basis of the identified
criteria in order to achieve another objective of this study. This will cause the numerous identified criteria to be
replaced with few, more concise and uncorrelated principal factors. For the explorative factor analysis using the
SPSS software ‘principal component’ method and ‘direct oblimin’ oblique rotations which were used as methods
of factor extraction and rotation respectively. The result of the analysis generated values of 0.793 (above 0.5) and
0.0003649747 (less than 0.05) as shown in table 6.15 which were gotten for KMO and Bartlett tests of sphericity
respectively, signifying that the data set is appropriate for factor analysis and the sampling is satisfactory (Pallant
2013). The results is interpreted retaining all factors with Eigen value of one and above, while criteria with factor
loading of +0.3 and above or -0.3 and below were taken as part of the offspring of their principal factor (Child,
2006). The output of the analysis was of nine components which represented 62.581% of total variance as
presented in Table 4.

VI. PROPOSED FRAMEWORK FOR END-USERS STAKEHOLDERS MANAGEMENT
IN PPP ROAD PROJECT IN NIGERIA
A well-established guiding tool theoretical framework is needed to accommodate the marginalised end-user
stakeholders of PPP toll road project in developing country like Nigeria. This will bridge the gap of ostracism
between the private and public sector on any PPP orchestrated projects. The inevitability of end-user’s
stakeholders’ participation in PPP projects will be abolished. The innovative idea of this framework is to showcase
the respondents’ attitude of both Lekki-Epe and Apakun Muritala Muhammed toll road projects as a hypothesis
for infrastructure development. This framework demonstrates the vigorous process that should be taken in
engaging end-users’ stakeholders during any form of PPP arrangement most especially toll roads project.
Seven (7) extracted factors were eventually used for the design of the final framework instead of nine (9) extracted
factors from the principal component method of factor extraction; this was done because of two (2) non-
contributory offspring from the extracted factors schedule. This now formed the fundamental basis for end-users
stakeholders’ participation in PPP toll road project in any developing country like Nigeria. The framework is
designed to give end-users stakeholders assured intensities of influence on any form of PPP arrangement.
Henceforth, end-users’ stakeholders’ engagement under any form of PPP will now become an essential focus in
incorporating their values, concerns and needs into any corporate and governmental process in decision-making.
Below is the proposed framework designed for the effective participation of end-user stakeholders of any PPP
road construction projects (see fig 1)
Figure 2: Proposed Framework for End User Stakeholder Management in PPP Projects in Nigeria

VII. DISCUSSION
It is not surprising to hear that PPP projects has become unsuccessful due to opposition from end-users
stakeholders (Akintoye et al., 2011). The two PPP road project considered for discussion are constructed to
alleviate traumas that has befell on the public through the incessant influx of masses from the rural areas seeking
wealth, employment and supposed better quality of life (Babatunde et al., 2016). A critical worry in Lagos state
Nigeria is the lack of infrastructure development, to keep up with the pace of urban spread and densification
(Adeniyi and Ogunsemi, 2011). This has resulted in significant pressure on the current available infrastructure
(Oyedele, 2012). The end-users stakeholders usually do not kind-heartedly accept to the divesting of “public
resources” in any way, either through PPPs or privatisation (Baroudi and Rapp, 2014). The influence of end-
users stakeholders in construction project cannot be overemphasised (Amadi et al., 2014). It is therefore necessary
to properly measure the acceptance of the end-users stakeholders for any PPP toll road project by finding
ways of mitigating any nervousness for residents before the commencement of any project (Yang et al., 2011)
The framework will allow the government to consider the utmost priorities of end-users stakeholders when
entering into any form of PPP toll road arrangement (Ponnappa, 2014). Engaging the marginalised end-users
stakeholders sustains the security of lives and properties amongst the host communities throughout the execution
of PPP toll road project (Gangwar and Raghuram, 2015). The study has revealed the non-inclusion of end-user
stakeholders which is definitely injurious to the success of PPP project (Opawole and Jagboro, 2016; Odeck and
Kjerkreit, 2010). This shows the effect of ambiguous attitude of the private investor through the generated results
from the final extracted factors as discussed below
Benefit Realisation and Community Participation
Creating jobs for residents: The end-user stakeholders are facing multiple challenges in securing jobs during PPP
construction projects (Newton and Glackin, 2014). The main concern of the private investor is about lack of
construction knowledge by the stakeholders (Kwon et al., 2014). The private investor relied on external workers
in particular with labour intensive construction works experience but the employment seekers in the project areas
are mostly youth with little or no experience (Neuman and Smith, 2010). The only potential way of alleviating
these fears is to build trust between the community stakeholders and residents end-users that are willing to
participate in construction project (Pennanen et al., 2013). It is impossible to test the inexperienced end-user
stakeholders with a herculean task of that magnitude. The residents that specialized in road works are few in
numbers and the possibility of creating new jobs through the highway management and maintenance are
cumbersome (Huong et al., 2012). Hiring unskilled artisan within the project area becomes worry due to the influx
of potential job seekers. This has resulted to frustrations amongst end-user stakeholders at the local level.
Improving local flooding and drainage works: Floods and high-water levels can considerably affect
environmental activities of end-user stakeholder of any developing community such as the prescribed project area
(Zumrawi, 2016). This action encourages road closures due to landslides, landslips, submerged and inundated
bridge supports. Upgrading infrastructure facilities like roads causes some temporary changes in drainage systems
during construction phase. This happens when drainage path, culverts among others are yet to be replaced or
installed (Zumrawi, 2016). Roadway floods can be induced by some social (human related effects) or natural
(rainfall) or other related factor predominantly heavy rainstorm (Ou-Yang et al., 2014). Lekki-Epe expressway
happens to be a victim of such circumstance where drainage networks are not rhetorically friendly. The existing
drainage networks in the two prescribed project area are considerably narrow which quest for upgrading before
the advent of PPP program. The modification measures that were carried out later relieved the community drainage
problems.
Repair of minor local roads: Pavement Management Systems (PMS) are established to guarantee authentic
management of local road network, systems and repairs (Kenley and Hartfield, 2014). The main objective of
managing local minor roads is to obtain positive results in road asset accountability which can benefit the end-
user stakeholders of the project area. Therefore, local minor roads within the project area should be observed from
an adaptive exposed system with the mind of satisfying the end-user stakeholder’s need (Kenley, 2014). For a
road to be more programming, realistic and schedule, planning that will accommodate development must be
assured (Bosher, 2014). These involved change in road geometry, installation of speed bumps cum reduction of
sharp horizontal curves and improvement of sight distance (Hassler and Kohler, 2014). All features are not visible
which invariably reduces business activities and patronage within the project community. The private investor
concentrated on the major road leaving the local minor roads that supposed to be an enabling access to social
services like schools, markets and modern health facilities. That is the major reason why reconstruction or
rehabilitation of those facilities becomes important to the community stakeholders.
16. Proposed Framework for Effective Management of End-User…
www.ijmrem.com IJMREM Page 23
Giving incentives to local residents during road work: Although, no study has observed whether or not to
provide incentives for residents of any PPP project (Luo et al., 2010). Further investigation shows that introducing
incentives in PPP project increases the level of local infrastructure benefit (Martinez-Bravo et al., 2011; Wong et
al., 2013; Martinez- Bravo et al., 2014). The methods of giving out incentives to local residents needed plans such
as evaluation and monitoring indicators for gauging implementation performance, outcomes and impacts on the
community stakeholders during construction of PPP road arrangement (Mu et al., 2011). The quality of
community infrastructure projects may be affected if certain incentives are not considered (Zhang et al., 2006;
Wong et al., 2013). Lobbying for incentives in terms of financial gain by the community leaders always hinder
the benefits expected by the end-user stakeholders of the project neighbourhood (Martinez- Bravo et al., 2014).
In order to fulfil the utmost desire of the end-user stakeholders of the project area, the community leaders should
foreclose any act of indecency by supporting the residents in achieving their desired interest.
Environmental Impact
Avoid damaging of (or replacing damaged) natural habitats: Despite the fact the road construction projects
can improve traffic and reasonable issues in society; they can also damage enormous areas of cultural artefacts
and natural habitat and put increasing pressure on community infrastructure such houses, schools, markets and
offices (Maji and Jha, 2012). Several machineries and vehicles that were used during construction at various stages
(such as jack-hammers, pay loaders, tippers, bitumen sprayer, graders, excavators and so no) damaged natural
habitat along the neighbourhoods of the project routes (Li et al., 2016). This also affects water ponds, mangroves,
fish ponds, and poultries among others. Ecological representations should have been integrated during the design
stage in order to incorporate natural habitats that could be damaged. The water pollution caused by the oil that
was drained from the earthmoving equipment during the PPP projects resulted to further degradation through
percolation and infiltration in the earth surface, endangering the quality water expected to be useful for community
stakeholders living within the vicinity of the project areas. This was evidenced by the presence of shallow wells
in most of the communities and villages along the project neighbourhoods. The traditional ruling classes along
Lekki-Epe neighbourhood were unable to protect the habitat of affected stakeholders during construction. To
avoid all these hypothetical damaging impacts of the community natural habitat, more research becomes necessary
in order to understand the factors that can sustain and shape the community stakeholders when such occasion
arises.
Avoiding local water pollution: The water pollution can be avoided by erecting and installing control devices
such as dewatering, contour drain, silt fence; flocculation and retention ponds (Al-Ani et al., 2014; Ahmad et al.,
2014). These will avoid residue and substantial pollutant from construction site which could possibly disturb all
the three scopes of sustainability such as social, environment and economic development (Ab Rahman et al.,
2010). The level of sediments emanated from construction site is huge, which normally released to water bodies
or occupies the whole land (Jeffress et al., 2011). The quality of surface water within the host communities were
deteriorated as a result of an increase in the runoff of storm waters loaded with sediments. This influences the
risks of quality water (due to pollution as a result of discharge of pollutants and waste water), river sedimentation,
soil erosion, stagnation of water in borrow sites, landslides, silting of soils, contamination of the water points
used by stakeholders (McPhee and Aird, 2013). During construction, contractors are ignorant of the magnitudes
of their construction programmes and implementation on the problems of sediment and erosion when it occurs
(Belayutham et al., 2016). This consequence coupled with the opening up of hill areas along the toll road for
settlement as a result of upgrading of the road resulted to greater amounts of runoff flowing into the low lying
areas affecting the community stakeholders by contaminating their drinking water. The growth and construction
plan of communities and major economic areas should have been incorporated and harmonized in the initiating
design (Prince et al., 2013; Duarte et al., 2015). The design must also involve environmental plan that will
encapsulate zoning of water reticulation programs amongst the end-user stakeholders of the project community
(Lu et al., 2015). These will instil confidence in the mind of affected community residents.
Noise level and air pollution: These are expected and unavoidable especially during and after the construction
phase of the project. However, much research has shown the influence of either noise or ambient air pollution on
humans’ health (Basner et al., 2014; WHO, 2013). Insufficient studies have examined the two environmental
experiences during after engineering construction. Intellectual utility happens to be one of the results that were
proposed when traffic noise and air pollution affects any stakeholders (Basner et al., 2014; Block et al., 2012).
These happens when road construction activities is going on and also the movement of earthmoving equipment.
The various vehicles and machinery that were used during the various stages of construction and site restoration
emitted various gaseous pollutants such as NO2, SO2 and CO among others (Clark et al., 2012; van Kempen et
al., 2012).
17. Proposed Framework for Effective Management of End-User…

These had serious negative effects on air quality that was inhaled by the community stakeholders of the
neighbourhood. Toll road development will definitely increase noise and vibrations due to the fact that gravel and
loose soil coupled with bituminous asphalt generate noise and odour that will not be suitable for stakeholders
living in the neighbourhood of the project. Based on this premise, only government can promulgate law that can
control noise and unwanted pollution in the country.
VIII. CONCLUSION
Public Private Partnership is generally not universally acceptable due to its multifaceted underpinning
philosophies, but other partnership arrangements have been tried by academic and industrial practitioners but to
no avail. There are apprehensions relating to marginalization, negligence and public outcry when the PPP project
was implemented at the detriment of community stakeholders but findings from this study shows that PPP became
an option for the nation discussion when Nigeria government is facing serious limitations to budgetary allocations
at all levels. The progress and development of PPP had been faced with several challenges especially in Nigeria
as an emerging economy country due to the marginalisation of end-user stakeholders of the project area. The
findings also revealed the significant importance of end-user stakeholders for any successful PPP toll road project.
The government with private investors should engage end-user stakeholders from the inception to the final phase
of any PPP toll road project by providing infrastructure services where necessary. These are the bedrock of end-
user stakeholder’s needs in terms of social inclusion and equity, productivity, environmental sustainability and
quality of life. The proposed framework can further solve the problems of most of the challenges expected to be
encountered in any PPP oriented project across the globe.
