“…In the works of Olawale & Sun [3], the recurring helplessness of research efforts towards decimating cost and time of construction project delivery failure was resonated in their presentation, that despite the availability of various control techniques and project control software, many construction projects still do not achieve their cost and time objectives. They posited that research effort has only been central to the investigation of causes rather than factors inhibiting effective control of project.…”

“…The Olawale & Sun [3] study precipitated 90 Mitigating measures against top five leading factors of design changes, risk/uncertainties, in accurate evaluation of project time/ duration complexities and non-performance of sub contractors. Against this backdrop, a confine point of what causes over runs in construction projects was them identified by the vacuum between inexperience project management factor and low skilled manpower factor used in construction projects.…”

“…Pitagorsky [2] noted that a successful project satisfies its client and sponsors with an outcome that achieves objectives within time and cost constraints, maintain and promotes harmonious relationships among the project stakeholders. Further, Oladapo [3] submitted that a project is considered successful when it is completed on time, within cost and to the required quality standard and a project that does not meet any of these objectives is considered to have failed.…”

This paper did a survey of literature on construction project performance. The industry's consensus on construction project performance estimators are well validated by these literatures as time, cost and quality. The findings showed that poorly performing construction projects are characterized by cost and time overruns as evident in high cost of construction, low quality work and time escalations. Research attempts in the industry to respond to these negative impacts on performance have yielded results in terms of precision predicting models for contingency applications and the stationary identification of cost overrun attributive factor.

“…These changes over and over again lead to rework [2] which can degrade the project performance [3]. Without proper change management strategy [4], undesired design changes will result in unexpected rework which lead to delays and disruptions [5]. Delays and disruptions have negative effects on construction project performance [6], [7].…”

“…Olawale and Sun [4] revealed that construction projects globally share some key characteristics. This is further supported by Abdul-Rahman et al [11] in the synthesis of preceeding studies where design changes have been named as the critical factor for project delays and cost overuns in construction project at different parts of the world.…”

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.

The significant amount of time needed to prepare concise and cohesive texts is among the reasons why extensive texts proliferate in organizations. Extensive documents are more likely to have low cohesion among their various sections, which may lead the reader to perceive the information as being of low quality. This research addresses this issue by presenting a tool (Text Matrix) composed of procedures and algorithms coded in software, with the aim of analyzing cohesion between the text sections in extensive documents. A design science research approach was applied to develop, test, and prove the usefulness of the Text Matrix. A total of 127 academic advisors and advisees were trained to use the Text Matrix and apply it in the development of the extensive text of dissertations. An analysis both of those users' perceptions and of variations in network density among 41 extensive texts that they improved through the analyses performed by the artifact proposed in the present study demonstrated the ease of operation and effectiveness of the Text Matrix to identify parts of extensive texts associated with cohesion failures that could be connected by cohesion devices or even excluded from the extensive text.
