“…Identification of the common problems experienced on past projects in their construction business environment is a good option (Long et al, 2004). Frimpong et al (2003) revealed that project management tools and techniques play an important role in the effective management of a project. PMBOK defines Project Management as the application of knowledge, skills, tools and techniques to project activities to meet the project requirements (PMI, 2008).…”

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.

A Conceptual Framework for Managing Design Changes in Building Construction

Abstract. Design changes have always been an innate feature of the construction industry. Despite the various project management techniques, many building construction projects still fail to achieve their time and cost objectives. This paper aims to focus on design changes as a major cause of time delays and cost overruns. It seeks to discuss the causing factors of design changes in building construction projects and highlighting the resulting rework that is detrimental to project performance. Hence, this paper also aims to present a conceptual framework which was developed to better manage design changes through clued-up management decision to avoid future claims and disputes. Recent and current literature is examined and reviewed. The review approach was based on related literature to identified themes. The existing literature is summarised into five discrete themes of "design changes", "rework", "time and cost overruns", "communication" and "decision-making". The synthesised literature is subsequently utilised in the development of conceptual map which provided the direction for designing the conceptual framework. Extensive review of preceding studies on causes of time and cost overruns reveals that design changes is identified as one of the significant factors. However, there are limited studies in this domain. The discussion presents a knowledge gap of linking design changes and rework with decision-making in project management. This finding suggests the need for further empirical study. The framework stresses the importance of communication and management decision as the control mechanism. Researchers and practitioners in construction management field will find this study useful in understanding the causing factors of design changes and its detrimental impacts to project performance which risk the project to claims and disputes. The conceptual framework presents an imperative outcome to encourage further research in developing conceptual causal model of design changes which shows the key causal variables and their feedback loops.

“…In a similar finding in Malaysia, Memon et al (2010) supported the previous findings that contractor inexperience and inadequate experience of labour are the major factors contributing to poor technical performance of small size local government projects in developing countries. Skill and technical competence of contractor's workforce, contractor's ability to identify and mitigate technical and schedule/programme risks, contractor's compliance with technical requirements are the major factors identified as having negative influence on the technical performance of projects in Iran and Ghana (Jafari, 2013;Frimpong, Oluwoye and Crawford, 2003). However, in Vietnam, Luu, Kim and Huynh (2008) argued that the inability of the firms to recruit and retain qualified technical staff, inaccurate detailed working drawings and lack of good cooperation among the parties involved in construction activities are the main factors contributing to projects' poor technical performance.…”

Abstract:The technical performance requirements of projects posed a challenge to the sustainable development of small size local government projects particularly in developing countries. Studies in the past focused mainly on the performance of major foreign construction firms mostly owned and operated by expatriates. Very few researches however, have been conducted to assess the relationship between major cost factors affecting technical performance of small size local government projects. This study is aimed at assessing the relationship between major cost factors that affect technical performance of small size local government projects in Nigeria. Survey instruments were administered to major stakeholders in the construction industry comprising of project clients, contractors and consultants using proportionate stratified random sampling method. A Warp partial least square-structural equation modeling (PLS-SEM) software algorithm was used for the analysis of collected data. The software is one of the powerful software for data analysis and has an advantage of providing p values based on the structure of the research model. The study concluded that cash flow problem, fraudulent practice and nature of construction environment are the major factors affecting technical performance of local government projects in Nigeria and further recommended the use of mediator variables like pay for performance and advance payment policy to minimise such negative effects. Governments in developing countries should devise a good cash flow policy and impose stringent penalties against any party involved in fraudulent activity.
