Abstract: The use of design-build (DB) and construction-manger-at-risk (CMAR) delivery methods have increased significantly in water and wastewater projects. Water and wastewater owners are at the forefront of using these alternative ...

Abstract: Changes made during the construction period generally generate claims, cost overruns, and schedule delays. Although there are publications relating to these concerns, because of geotechnical reasons on transportation ...

Abstract: State DOTs have been using traditional contracts with prescriptive specifications to procure road maintenance work. However, performance-based contracts (PBCs) have been used for design-build (DB) projects after the DB ...

Abstract: The road maintenance workload for transportation agencies increases every year. To maintain roads effectively, one contracting method state Departments of Transportation (DOTs) use to outsource is performance-based contracting ...

Abstract: While public-private partnership (PPP) is not an entirely new development in US procurement, the public and private sectors have adopted and applied it slowly, placing the United States behind the PPP global transportation ...

Abstract: Among various project delivery methods, there is a growing tendency to deliver transportation infrastructure projects, particularly highway projects, through public–private partnerships (PPPs). This necessitates further ...

Abstract: Because of depleting global energy resources, an economic necessity in the United States is to reduce energy consumption. The construction industry is proceeding to reduce the energy consumption of buildings by developing ...

Abstract: The vast majority of highway and street projects in the United States are procured and constructed by state or local governments using the design-bid-build (DBB) project delivery method. In the DBB method, the contractors ...

Abstract: For design-bid-build (DBB) projects, the assumption is that because the bid cost of the lowest bidder is usually below the estimated cost of the project, change orders during construction will increase. This study collected ...
