TO STUDY THE DELAY TO CONSTRUCTION PROJECTS -CAUSE, EFFECT AND MEASURES TO REDUCE
Delay to projects is one of the foremost concerns of the construction industry in the India. The delays to the projects are affecting the economies throughout the world. Delay to projects mean the slowdown of development in all other related fields. The main aim and objective of this dissertation is to evaluate the various types of delays and the reasons for those delays that are currently affecting the projects in the India. Measures from previous researches to reduce or eliminate these delays by methods of mitigation or acceleration are analyzed for the case studies considered for this research. There are various types of delays which are identified. It is important to identify whether the delay is critical or not as identification of critical delays helps in taking appropriate measures at the correct time. The delay may be non excusable (contractor caused) for which the client and the consultant need to have project management tools to effectively manage the delays or compensable (client caused) delays which are due to the client. The delays may be by either parties and can be concurrent. The reasons for delays are primarily due to an unreasonable project scope, inadequate early planning and the absence of risk management systems. The contractor further contributes to delay due to lack of resources and labor productivity. Over ambitious estimates, incorrect task assessment ,lack of task clarity, design/ approval delays and interference in the decision making process by the client add on to the delay.
ANALYSIS OF FACTORS CONTRIBUTING DELAYS AND CLAIMS IN CONSTRUCTION PROJECTS
Construction activities are the most competitive and it involves higher risk with minimum profitability due to competition. Construction of any infrastructural work involves complex management skills related to manpower, materials, plant, machineries, new technologies etc. It also involves many agencies interdependent on each other like the planners, structural and functional designers including various types of specialized engineers and it also includes support of financial institutions, insurers, contractors and specialized contractors. As there are prevailing labour bye laws it needs special care of their well beings. In such kind of complex and intense framework some disputes is quite natural between the agencies involved in such activities which further results in claims management as the unsettled dispute finally leads to financial claims. Higher incidences of disputes are generally reported from the construction contract. Even if there is an appropriate understanding of construction contract clauses from the agencies in the agreement yet claims seems to be a major crisis in the construction sector. The research reported in this paper aims in identifying the major factors responsible of project delay that may give rise to claims for delay damages. The in this paper research mainly highlights on finding the major components of claims with perspective of contractor for delay damages.
Construction Delays Causing Risks on Time and Cost -a Critical Review
There is an increase in the number of construction projects experiencing extensive delays leading to exceeding the initial time and cost budget. This paper reviews 41 studies around the world which has surveyed the delay factors and classified them into Groups. The main purpose of this paper is to review research which has categorized the causes responsible for time delays and cost overruns in projects. The intention was to see whether these causes are valid for projects being executed in Sabah East Malaysia allowing a mitigation plan to be prepared. The collected list has 113 causes for delays which were categorized into 18 different groups. Most of the research has analysed the responses from Questionnaire surveys. The collected data are used to rank the problem factors. The data are further used to investigate and analyse the reported "Importance Index, Frequency Index, Severity Index, Relative Importance Index, Relative Importance Weight, Weighted Average, Mean, Standard Deviation and Variance". The collective comparison has revealed that the ranking given by all the researchers is not the same. Further each and every study has different rank ratings from different group. This review paper attempts to provide an updated compilation of the earlier studies on ranking of the delay causers, which are never similar and constant for universal projects. From the critical review, it is concluded that this type of research requires a different method or approach to generate meaningful answers and that there is a strong case against opinion surveys. concerned with quality, time and cost and yet the majority of construction projects are procured on the basis of only two of these parameters, namely time and cost (Bennet and . The literature emphasises time as an indicator for project success.
Delays are unique one in every of the largest issues construction companies are facing today. Delays will result in several negative effects like lawsuits between house owners and contractors, exaggerated prices, loss of productivity and revenue, and contract termination. Thus, comprehensive study on delays in construction projects is important. Present study works on identification and ranking of causes of delay in residential construction projects in Indian context. This paper identifies the causes of delays in residential construction projects of Indian construction industry. Total 59 causes were identified under 9 major groups. Total 50 respondents comprises of 20 developers, 17 contractors and 13 architects who participated in this field survey. This paper suggests an approach to carry out ranking of causes of delay by two different techniques: Relative importance index and Importance index based on degree of severity and degree of frequency and also discuss about the ranking of the causes. Results were shows that out of top 10 factors total 5 factors were common in ranking by both methods. They were original contract duration is too short, shortage of labours, delay in material delivery, low productivity level of labours, delay in progress payments by owner. Moreover, by both methods labour related factors ranked first while external factor was considered having least effect on delay as it is ranked last. All three parties agreed on that labour related factor was most important while external factor was least important. It is hoped that the findings of the paper will help the stakeholders to act on critical causes and further try to reduce delay of their projects.
Analysing factors affecting delays in Indian construction projects
Construction projects in India are experiencing widespread delays. Due to a dramatic shift in the capacity and volume of the Indian construction sector over the last decade, the need of a systematic analysis of the reasons of delays and developing a clear understanding among the industry professionals are highly crucial. Using a selected set of 45 attributes, this research first identified the key factors impacting delay in Indian construction industry and then established the relationship between the critical attributes for developing prediction models for assessing the impacts of these factors on delay. A questionnaire and personal interviews have formed the basis of this research. Factor analysis and regression modelling were used to examine the significance of the delay factors. From the factor analysis, most critical factors of construction delay were identified as (1) lack of commitment; (2) inefficient site management; (3) poor site coordination; (4) improper planning; (5) lack of clarity in project scope; (6) lack of communication; and (7) substandard contract. Regression model indicates slow decision from owner, poor labour productivity, architects' reluctance for change and rework due to mistakes in construction are the reasons that affect the overall delay of the project significantly. These findings are expected to be significant contributions to Indian construction industry in controlling the time overruns in construction contracts.
Analysing Delays of Construction Projects in India: Causes and Effects
Construction delays are common problems in civil engineering project in India. These problems occur commonly during project lifetime leading to disputes and legal action. Therefore, it is necessary to study and analyzed causes of construction delays. The opinion of construction experts was obtained through interviews. Subsequently, a questionnaire survey was prepared. A questionnaire survey is conducted to consider the time performance of construction projects in India to identify the causes of delay and their important index for delay factors could be computed. A total 78 causes of delay were identified during the research. The delay factors were grouped into eight major groups. The top-10 list was dominated by factors related to the contractor, owner and the project group. However, three owner group factors and consultant group factors, late progress payment, financial problems of owner, and improper study of design affects estimated quantity, were the first three factors on the list, which also had a high impact on the three project objectives. The remaining factors on the list were poor qualification of the contractor technical staff and project team, poor terrain condition, conflict between contractor and consultant, Poor site arrangement, management, and supervision, lacks of involvement of design team during construction stage, delay in obtaining permits from provincial/municipality, and distribution to public activities. Recommendations to manage the delay factors were presented. Significant relationships, between the delay factors and the three project objectives also were observed and discussed.
A Review for the causes of delay in Indian Construction Projects
Delays can be defined as time overrun or extension of time to complete the project. Delay is always the major loss to any construction project. As construction is one of the largest economic activity in India, the effects of delay are still in millions; which surely decreases the GDP of the country. Delay makes the process tardy and management of delay is extremely challenging as most of the projects do not meet the expected requirement and fails to perform within time. Therefore, various types and causes of delays should be studied accurately. There are many researches on construction delays but still some improvements are required, so there is a high requirement of a notable and feasible study on construction delays in India. The aim of the paper is to identify the causes of delays through literature reviews in Indian construction projects.
A Study on the Contractor Opinion of Delays in Construction Projects in the Makkah Region- KSA
2021
A contractors’ survey has been conducted to investigate the causes of delay in construction projects in the Makkah region of Saudi Arabia. The aim is to determine the most significant delay factors from the contractors’ point of view. The study is part of a series designed to explore in-depth causes of delays from different stakeholders in the construction industry. A comprehensive survey of seventythree questions under eight groups has been used to explore a wide range of possible delay factors. The highest ten factors in frequency relative importance index (RII) are found to be (1) delay in decision-making commensurate with the agreement of the parties to the project (RII = 0.89), (2) unqualified and unskilled workforce; low productivity of labor; hazardous substance (RII = 0.87), (3) suspension of work; change to the project by the owner; delays due to unrealistic enforced contract duration; delay in the approval of submittals, design drawings, shop drawings; lack of design team ...
