“…Unclear project definition in contracts prepared on the basis of conceptual design and clients' organizational behaviors, such as change orders, are main causes of claims in international hydropower EPC project delivery [34]. Timely process of claims caused by the implementation of owners' orders for variation should be an emphasis of design-related contract management of hydropower EPC projects [58].…”

Extant literature lacks a systematic framework addressing the mechanisms of the alliance functional process and its impacts on management activities together with performance in delivering Engineering-procurement-construction (EPC) projects. This study quantitatively investigates the cause-effect relationships among these themes by building and validating a conceptual model of contractor-designer alliance in international hydropower EPC projects. With the support of data collected from an industry survey, the results reveal the key design problems, application of contractor-designer alliance, design management level and performance, which form a sound basis for design management emphasis in EPC activities, e.g., sufficiently considering sustainability of hydropower projects by incorporating environmental, social, and economic factors into designs. The path analysis indicates that the contractor-designer alliance can not only improve design performance by enhancing design management, but also directly promote design performance. This research has significant contributions to the body of knowledge by building interdisciplinary linkages between the areas of alliance, design management, and performance, theoretically demonstrating the mechanism of how interfirm cooperation functions to achieve superior design outcomes of hydropower EPC projects. Understanding these causal relationships will be crucial for contractors and designers to optimally allocate their complementary resources for seeking better design solutions in dealing with both technical issues and sustainability factors.

“…Productivity is commonly defined as the quantity of work produced of work output per unit of input or effort (Klanac & Nelson 2004). Loss in productivity is usually experienced by contractor and entails the completion of work at less than the planned rate of production.…”

“…Loss in productivity is usually experienced by contractor and entails the completion of work at less than the planned rate of production. There has been a considerable amount of research about the factor that causes loss in productivity common factors include acceleration (directed or constructive) adverse or unusually severe weather, the cumulative impact of multiple changes and revisions, site or work area access restrictions, site conditions, untimely approvals and responses to labour market conditions (AACE, 2004;Klanac and Nelson, 2004).…”

“…Previous studies have tried to locate the causes, including project characteristics, site conditions, project execution, weather effects, supervision effects, management of time, local labor market conditions, and availability of tools and construction equipment (Klanaca and Nelsonb 2004). Furthermore, for assisting delay analysts in estimating lost labour productivity in construction claims, more complete causes of lost productivity are collected in a report of AACE International Recommended Practice (AACE, Inc. 2004).…”

“…Notably, the problem of lost productivity usually results in the claims from the contractor. Contractors assert claims for loss of productivity when the anticipated means, methods, techniques, scheduling, or work sequence are altered by events or circumstances outside the contractor's control, and the contractor is entitled to relief for the loss (Klanaca and Nelsonb 2004).…”

Schedule delays commonly appear in construction projects and result in delay claim progressively. Several studies have proposed various schedule delay analysis methodologies, however, most of the studies focused on the analysis of surface data (as-planned and as-built schedules), few of them on evaluating the effects of root causes, such as lost productivity. Loss of productivity is usually experienced by a contractor while accomplishing its works less than planned rate of production. Based on the literature review on lost productivity, this study further evaluated delay analysis methodologies, professional project management software and commercial delay analysis software to identify the capabilities of those methodologies and systems in dealing with the problem of lost productivity. Research results show that evaluated delay analysis methodologies, professional project management software and commercial delay analysis software cannot deal with the problem of lost productivity appropriately. That is, developing a comprehensive delay analysis method considering lost productivity is required.
