Abstract: Unit-price contracts are common in public construction projects. Such contracts expose contractors to economic risks due to deviations between owner-estimated quantities and actual quantities of work. Contractors typically ...

Abstract: Construction operations in airport expansion projects often attract wildlife species to critical airport traffic areas leading to an increase in the risk of wildlife–aircraft collision accidents. Airport operators and ...

Abstract: In nonlinear construction optimization problems, the capability of current optimization algorithms to find an optimal solution is usually limited by their inability to evaluate the effects of changing the value of each ...

Abstract: Airport expansion projects often require the presence and movement of construction labor and equipment near critical airport traffic areas. This close proximity between construction activities and airport operations needs ...

Abstract: Planning construction site layouts involves identifying the positions of temporary facilities on site, and accordingly it has a significant impact on the safety and efficiency of construction operations. Although available ...

Abstract: Airport expansion projects often require the presence of construction personnel, material, and equipment near airport secure areas/facilities, leading to an increase in the level of risk to airport security. Construction ...

Abstract: The growing demand for maritime transport imposes several challenges to port authorities, including reducing port congestion, planning for expansion projects, and allocating budgets for such capital projects. To address ...

Abstract: Unit-price contracts are awarded based on estimated quantities while payment to the contractor is based on actual quantities of work. In many cases, estimated and actual quantities never perfectly match each other for ...

Abstract: In building construction, contractors are typically selected through competitive bidding or negotiated contracting, in which the project price is the major selection criterion. A contractor’s safety performance is still ...
