Rework investigation in residential building projects: Cost, factors and effects

AbstractThis article aims at investigating rework cost, factors and effects in residential building projects in the West Bank – Palestine. Questionnaire survey is used to collect and rank the main factors and effects of rework from consultants' and constructors' point of view. Respondents show that more than 80% of the projects completed with rework cost of value greater than 5% of the total project cost. Overall, respondents' view concludes that the top rework factors include: mistakes in design, unskilled labors, unqualified subcontractors, non-conformance with required specifications, and bid awarding policy. Respondents indicate that the main effects of rework are cost overrun, project time extension, material waste excess and profit reduction. Spearman correlation test concludes a good correlation between contractors and consultants in ranking of rework factors and effects. Data collected from 47 residential projects reveal a high rework impact on cost overrun in construction projects. The results of this study would be helpful for researchers and professionals to guide their efforts to minimize rework in construction projects and to improve projects outcomes in term of cost, time and quality.

A Review on Adoption of Bim in Reducing Construction Rework

In the construction industry, the aim of project control is to ensure that the projects are completed on time, within budget and achieving other project objectives .Rework is one of the most major problems in the construction industry. It has an impact on time, cost, quality, and practically every other project success factor. There is always a significant loss of resources, materials, investments, and workforce-time as a result of rework and poor use of resources and materials in the works. Rework may be reduced by designing and planning with full understanding of customers and stakeholders, good communication amongst project aspects, applying quality management systems, and utilizing Information Technology. Because of the worldwide expansion of IT and the widespread use of BIM ,which coordinates all of the software and parts of the construction--the appearance of mistakes and inconsistencies has been drastically reduced in recent years, allowing specialists to realize their full potential in doing projects. To the best of the author’s knowledge, this study is to use actual project data to measure the effects of BIM implementation on rework in construction projects. The study's findings enable practitioners to develop techniques to reduce rework with BIM implementation, enhance project cost and time performance, and increase project delivery efficiency

Influence of rework on construction project performance in Nigeria

One of the key reasons for setbacks in construction projects in Nigeria is rework. In order to create efficient containment and reduction strategies, this study examined the causes of rework in construction projects, its influence on construction project performance, and proffer solutions to the causes of rework based on extant studies. A total of 140 questionnaires were distributed to the stratified population of various construction professionals. One hundred and eight questionnaires were duly completed and returned. Data were analysed using mean weighted value and regression analysis. The data analysis results revealed that poor coordination of design, the lack of effective quality management practices and alteration made at the clients' request were the topmost causes of rework. In addition, poor morale, time overrun and disputes were the first three most rated impact of rework inimical to construction project performance. It was concluded that the incidence of rework influences projects performance as it brings about poor morale of the workforce and dissatisfaction among end user. It was recommended that adherence to the solutions proffered to the topmost causes of rework will go a long way in improving construction project performance.

Analysis of factors causing rework and their mitigation strategies in construction projects

Rework has turned into a problem in the building sector since it causes unwanted and pointless effort wastage. Both the design and construction phases of construction projects are affected, and it results in decreased project cost, quality, and schedule performance. Rework costs in large civil engineering projects might be anywhere between 5% and 20% of the contract value. It is crucial to effectively reduce rework as much as possible. Before rework can be managed properly, its underlying causes should found. So as to quantify rework in construction projects. The objective of this study was to find the contributory factors in the building sector, as well as how it affects project costs. The reasons for producing rework in construction projects and mitigation strategies to prevent rework in construction projects were identified based on research of the literature and expert opinion. Data from construction industry experts was gathered through a questionnaire survey. After statistical analysis of the data obtained from the questionnaire survey, structural equation modelling (SEM) was created. The findings of this study demonstrate that important reasons for rework were a lack of coordination and communication, errors and omissions, and changes brought about by parties. The results could improve the performance of the construction project by helping everyone understand why rework happens and how to cut it down as much as possible.

Towards contracting strategy usage for rework in construction projects: a comprehensive review

Rework has been the core of attention for several years in the industry and academia as it affects the performance of projects. However, the trend of rework academic papers indicates an increasing rate in recent years; the overall research lacks a comprehensive review of the implemented theories and proposed models to explore further directions for rework management. Thus, to achieve a better understanding of rework it is necessary to perform an extensive review. This research aims to explore various insights from rework-related articles, discuss major research areas, and identify gaps for future studies looking closely at construction contracts. The selected articles are from three databases: “Scopus, Web of Science, Google Scholar”. The findings are categorized into six study areas: sources of rework, models and solutions, management and strategies, theories and techniques, rework impacts, and factors affecting rework. The analysis of the employed techniques across these topics showed that System Dynamic Modelling, Action Research, Analytic Hierarchy Process, and Regression have been used more frequently than other methods. The comprehensive review also shed light on the new ways of thinking, analyzing, and controlling the impacts of the rework. This paper proposes the assessment of rework causes in the conditions of contract which provides opportunities for improvement of the construction contracts.

The common causes of rework in construction contracts: a diagnostic approach

PurposeThe high rate of rework that occurs in construction projects has a negative effect on the performance of the construction projects. Although several mechanisms have been implemented to control reworking, a comprehensive list of rework causes is yet to be provided to present the common causes that contribute to rework in construction contracts. This paper aims to investigate the most common rework causes that need to be addressed in construction contracts.Design/methodology/approachA mixed-method using both the qualitative and quantitative approach is used in this paper. First of all, the study adopted a four-step literature review to introduce the rework research trends and provide statistical reports using descriptive analysis. Next, a comprehensive review has been completed using content analysis to identify the common causes of rework in construction projects. Finally, the common causes in construction contracts are further investigated through a quantitative questionnaire survey to validate the initial results.FindingsThe results of the review showed an increasing trend of publications on rework over the last three decades. Most of the studies were conducted in Australia, the UK, Nigeria and Hong Kong. Based on further investigation in the study area of sources of rework, 37 causes of rework causes were identified and classified in five groups. Then, the most significant causes of rework in construction contracts were compiled in the list of 22 items.Research limitations/implicationsThe paper’s reported result, contributes to the contract management body of knowledge by proposing a list of common rework causes that can be used by practitioners during the contract negotiation to prevent contractual issues. The result of the review can also be used for further investigation of the relationship between rework and contract conditions.Originality/valueThe proposed list of common causes of rework in construction contracts allows project parties to improve the terms of the contract in addressing rework, this could result in fewer contractual claims and disputes. The findings of this study will also guide the investigations into the contract conditions, thus the approach used is constructive.

Causes of Rework in Construction Projects in Ukraine

AbstractThe collapse of the Soviet Union was the cause of a significant decline in many economies of the newly created countries. However, many of them, including the Ukrainian economy, are slowly recovering. One of the largest branches of the economy in this country is construction, which, despite political turmoil, is constantly growing, especially in the private real estate development sector. Despite the fact that the construction market is constantly developing, it is limited by the costs of rework and alterations resulting from many reasons. The key negative effects of modifications to the results of the project are exceeding the budget and time of project implementation, dissatisfaction with the project team, violation of contractual requirements and lowering the quality of the final product. Therefore, the purpose of this article was to determine the reasons for the emergence of rework in the in Ukraine by analyzing the results of surveys conducted among construction enterprises.

A Model to Investigate the Effect of Work Ethic Culture on Dynamics of Rework in Management of Projects

The present study aims to investigate the effect of work ethic culture on rework in construction projects through a review of literature, surveys, and interviews with project managers. The main research question is what mechanisms can project manager use to balance the costs of personnel training, financial and language incentives, and implementation costs to finish the project with more profit and less rework. In this regard, modelling and data analysis is done using System Dynamics methodology. The results show that by considering work ethic, rework in the project is reduced from 46 % to 39 %. However, the project has been completed with 10 % lower cost and 26 % lower variance. Integrating the issue of rework with the culture of work ethic in the field of project management by at least one exogenous parameter has been studied, while in this study qualitative parameters have been converted to quantitative parameters using fuzzy inference system. The change in management approach to the issue of work ethics and the formulation of human resource strategies of large projects by human resource managers is one of the applications of this study.

USING SYSTEM DYNAMICS MODELLING PRINCIPLES TO RESOLVE PROBLEMS OF REWORK IN CONSTRUCTION PROJECTS IN NIGERIA

Rework in construction projects has brought in two major challenges: cost overruns and delay. In this regards a study was conducted by considering various construction projects in the South West part of Nigeria to understand the causes of rework and the interventions to mitigate it. Survey research methodologies followed by the conceptual system dynamics (SD) modelling were used in the analysis. This study identified the sources of rework in construction projects from the design related, the client related and the contractor related issues and attempted to derive policy/strategic interventions to limit or eliminate rework on construction projects and its delivery by using conceptual SD models based on the influence of the variables on rework. The findings include that inappropriate scheduling for time pressure or delay at the planning stage, lack of adherence to the specifications, and non-availability of skilled human resource are the major causes of rework. However, rework in construction projects would be reduced or eliminated through policy interventions, such as, achieving client satisfaction with scheduling for time pressure or delay at the planning stage, adherence to specifications ensuring quality of work resulting in client satisfaction, and the availability of skilled manpower ensuring quality management.

Analyzing Causes for Reworks in Construction Projects in China

AbstractAlthough rework is a common phenomenon in the Chinese construction industry and significantly affects project success, the reasons for rework remain largely unknown and most construction companies are unable to manage the issue effectively. To investigate the causes of rework in construction projects, a total of 39 causes were first identified through a comprehensive literature review and semistructured interviews with 13 experienced construction professionals in China. A questionnaire survey was further conducted to prioritize these causes, in which unclear project process management, poor quality of construction technology, and the use of poor construction materials rank the highest. Finally, a factor analysis revealed 11 major underlying dimensions of these causes, relating to design management, communication management, field management, project scope management, project process management, active rework, project plan changes, subcontractor management, contract management, owner capability, an...

Auditing the indirect consequences of rework in construction: a case based approach

There is little known about the indirect consequences of rework in construction projects, especially the financial costs. Therefore, this paper uses examples from a case study to demonstrate the potential indirect consequences and costs that are associated with undertaking rework in building construction projects. A novel taxonomy for categorising the indirect consequences at an individual level, organisational level and project level is presented. Based on the findings from examples derived from the case study, it is suggested that the incidence of rework can have a multiplier effect of up to six times the actual (direct) cost of rectification. To reduce these costs it is concluded that design and construction organisations must improve their quality management systems by including a quality system for continuously auditing, analysing and presenting direct as well as indirect rework costs.

Illustrative Benchmarking Rework and Rework Costs in Swedish Construction Industry

Following several studies investigating the causes of construction rework among some projects in the Swedish construction industry, we conducted this study in cooperation with R&D West, a group of construction companies in Sweden, to measure the costs of rework in construction projects. Rework has become an endemic feature of the procurement process in construction that invariably leads to time and cost overruns in projects. Thus, in order to improve the performance of projects, it is necessary to identify the causes and costs of construction rework. The research presented in this paper identifies, analyzes, and discusses the causes, magnitudes, and costs of rework experienced in seven Swedish construction projects. The findings revealed that the costs of rework for the case study projects were 4.4% of the construction values of the observation period, and the time needed to correct them was 7.1% of the total work time. The construction errors that generated rework were further analyzed according to their origins, types, and positions, causes of construction rework were identified and discussed, and preventive actions were suggested.
