Delay Analysis in Industrial Projects by using Relative Importance Index MethodIRJET Journal
This document discusses delays in industrial construction projects in India. It aims to identify the key causes and effects of delays by conducting a literature review and survey of consultants and contractors. The top five causes of delay identified are: (1) local political interference, (2) inadequate fund allocation, (3) improper project planning and scheduling, (4) delay in progress payments by clients, and (5) escalation of material prices. The major effects of delays are time overruns, cost overruns, and disputes. The study uses a Relative Importance Index method to rank factors identified from the literature and survey responses on causes and effects of delays and their perspectives.
The infrastructure construction sectors are usually complex. Zero risk construction projects are only an
assumption. The objective of this paper is to identify the risks factor associated with the urban infrastructure
construction projects causing delay. The research found that those risks are directly associated to clients,
contractors, sub-contractors that would cause delay in the construction work. Other factors are also
identified such as project, financial, political, technical, market risk, managerial, resource risk, and force
majeure. All risk factors affect the time, cost and quality performance of the construction project. From risk
management perspective, it is the process on which identifies the risks and analyzed with qualitatively and
quantitatively. All associated risks can treat by various mitigation processes and then mitigating method are
monitored to control the risks. Risk management distinguishes between success and failure of a project.
So, Nepal could use it effectively to meet its growing need of infrastructure and job opportunity

Effect of construction delays on project time overruneSAT Journals
This document discusses construction delays and time and cost overruns in infrastructure projects in India. It finds that about 57% of Indian construction projects experience time overruns. Major causes of delays include changes in plans, payments issues, improper planning, inexperienced contractors, and coordination problems. These delays contribute to projects exceeding initial time and cost estimates. Analysis of mega projects worth over 1000 crore from 2011-2012 found irregular increases in percentage time and cost overruns in 2012 compared to 2011. Some projects experienced over 200 months of delay and over 700% increases in projected costs. Addressing delays in land acquisition, equipment issues, payments, and changes in scope could help reduce overruns.
This document analyzes critical factors affecting construction project delays in the Pune region of India. A survey was conducted of construction companies to identify common reasons for delays. 82 potential factors were identified from literature review and categorized into project-level, owner, contractor, consultant, design, material, labor, equipment, and external factors. Respondents provided the frequency and severity of each factor on a scale of 1-5. The Relative Importance Index was calculated by multiplying the frequency and severity indices to rank factors. Legal disputes and ruling party issues in the locality were found to be the most critical factors based on their importance indices. The study aims to identify root causes of delays to help reduce unnecessary delays in future construction projects.

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.
