“…Again, Ijaola and Iyagba [41] also reported identical findings in both Nigeria and Oman. Another study by Al-Momani [19] reported that the main causes of delay in construction of public projects in Jordan are related to user changes. El-Razek et al [43] also have almost similar findings in Egypt, Ogunlana et al [17] in Thailand and Wu et al [44] in Taiwan.…”

“…Therefore, Love et al [60] suggest the communication and harmonious relationship between clients and their design team and the involvement of clients in the design process can appreciably cut designrelated rework. Key designer-related factors include natural growth of the project was not anticipated at the design stage, design errors as well as design and construction criteria are outdated and do not suit the present construction technology [19]. Modification to design was indicated as the second most important causes of change order in both Nigeria and Oman [41].…”

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.

“…One of the main objectives and policies of any public or private sector implementation of projects is to upgrade the performance process of the projects through the reduction of costs, completion of the construction projects within their contracted sum and time limit, and improvement of quality. Private housing project delays are often caused by circumstances that create barriers to the launching and further implementation of project activities [5].…”

Abstract. Project delays in the construction industry are a universal or large-scale observable fact affecting not only the construction industry but the overall economy of countries as well. As far as the Malaysian construction industry is concerned, project delays are common problems in the construction industry, particularly in housing development. The objective of this study is to evaluate and identify the causes and the consequences of project delays in private housing development projects in Malaysia, and the remedies that can minimize these delays. The top ten causes of delays are weather conditions, poor site conditions, poor site management, incomplete documents, lack of experience, financial problems, contract modifications, delay in the approval of major variations, contractor coordination problems with other parties, and construction mistakes and defective works. It has been analysed that the causes of the delays point to the contractor factors, which contribute to the major factors that cause project delays in private housing development projects. The consequences of the delays include time overrun, cost overrun, differences in opinion, negotiations, legal actions and total abandonment. Herewith are presented some recommendations to minimize these project delays.
