“…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. According to Hwang et al [45], client-related factors are (1) change of plans or scope by the client; (2) inadequate/incomprehensive project objectives by the client change in specification by the client; (3) financial problems faced by client; (4) impediment in prompting the decision making by the client; (5) replacement of materials by the client; (6) change in specification by the client; and (7) obstinate nature of the client.…”

“…Kaming et al [14] describe the magnitude of design changes depend upon pre-design site investigation, the completeness of working drawings available at the time of proposal and unpredictable circumstances during construction. Consultant's inability [55], design omission [15], [27], incomplete drawings [17], design errors [51] and quality of design [44] caused cost and schedule increases. Design changes constitute a major cause of failure in coordination of design information [28].…”

“…Similarly, modification of construction methods to suit current site conditions, contractor request for original construction methods to be replaced by a new method as well as improper construction or human-errors leasing to on-site repair work are listed by [44]. Poor planning of project caused errors in execution of tasks and inappropriate construction methods [27], [50].…”

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.
