The fate of many construction projects is determined using preliminary project cost
estimates. These estimates play a key role during the conceptual phase of projects; as in …

Preliminary project cost estimates are the first serious estimates made on a project. They
play an important role during the decision-making process, and are the benchmark with …

During the early stages of a project, it is beneficial to have an accurate preliminary estimate
of its cost. One way to make those estimates is by determining the amount of construction …

Recent earthquakes uncovered the potential risk of widely-used simply-supported bridges
(SSBs) to suffer severe bearing and pier damage, which may not be mitigated efficiently by …

This paper compares onsite concrete quantities to preconstruction estimates for 18 highway
bridges in Canada to quantify the differences in quantities and to identify the driving factors …

Conceptual cost models do not provide details of materials, equipment, or personnel that
make up construction cost. Therefore, obtaining project details for early resource planning …

The objective of this study is to analytically assess the effectiveness of a novel composite
rubber bearing (CRB), which is proposed to enhance both the displacement and damping …

Owners face challenges in setting priorities between potential projects to maintain,
rehabilitate, and improve their infrastructure. The estimated cost of each potential project is a …

Even for the right treatment, improper timing can have consequences: premature application
(treatment is applied too early) could mean wasteful spending even if users enjoy the …

Conceptual cost estimating is typically completed early in the project lifecycle when little
design work has been completed. Because little information is known at this early stage, the …
