While it is widely recognized that additional costs due to rework can have an adverse effect on project performance, limited empirical research has been done to investigate the influencing factors. The research presented in this paper aims to determine the influence of different project types and procurement methods on rework costs in construction projects. Using a questionnaire survey, rework ...

PATH (Partnership for Advancing Technology in Housing) is a new private/public effort to develop, demonstrate, and gain widespread market acceptance for the " Next Generation " of American housing. Through the use of new or innovative technologies, the goal of PATH is to improve the quality, durability, environmental efficiency, and affordability of tomorrow's homes.

With this study, a cross disciplinary team of the Center for Construction Policy Research has taken a first and significant step in documenting employee misclassification in the Massachusetts construction industry. This report documents the dimensions of misclassification and its implications for tax collection and worker compensation insurance. Misclassification occurs when employers treat wor...

Costs not directly attributable to or recoverable from production and sales are often loosely referred to as overhead costs. In construction, some of these result from the organisation structure, size and form of the enterprise, some apply more directly to site operations and some may lie somewhere in between. Overhead costs largely represent the enterprise’s operational capacity, including asp...

Controlling and minimizing coordination costs has been shown to be an important factor to reduce overall project performance in distributed software development. In this research-in-progress paper we investigate the effects of software complexity, software integration, distributed labor division policies, learning effects on software coordination costs. Drawing from data collected on 130 softwa...

Casing collapse is one of the major problems in oil fields, imposing a lot of costs on oil companies. This problem occurs not only at drilling times in some formations but also after the completion and production can lead to many problems. Analysis of the behavior of casing collapse in terms of geo-mechanics and solid mechanics could significantly meet the needs of the oil industry of Iran. In ...

The construction and demolition waste (CDW), which is produced by the construction process, presents 33% of the total waste stream in European Union in year 2010 (Eurostat 2010). A construction and demolition waste is generated during whole life cycle of construction design phase, realization phase, occupation phase and demolition phase. On the other hand, the sustainable design of construction...
