Production rates are significantly important for contract time determination procedures as these are essential for estimating the duration of every activity needed to complete a highway construction project. For this reason, ...

Schools have a unique place in the fabric of America. Yet there is growing evidence that poor indoor air quality (IAQ) leads to increases in student illnesses and absenteeism, decreases in academic performance, and increased ...

Prestressed concrete girders are commonly fabricated with 0.5-in. (12.7-mm) or 0.6-in. (15.2-mm) diameter prestressing strands. Recent interest in the use of larger (0.7-in. (17.8-mm) diameter) strands has been driven by ...

Autonomous vehicle (AV) technology has matured sufficiently to be in testing on public roads. However, traffic models of AVs are still in development. Most previous work has studied AV technologies in micro-simulation. The ...

Steel moment resisting frames (MRFs) are one of the most commonly used lateral force resisting system for steel building construction located in regions of high seismic risk. Although steel moment frames were studied ...

Current methodologies to measure road friction present several disadvantages that make them impractical for field data collection over large highway networks. Thus, it is important to study different ways to estimate surface ...

Layered soil profiles can complicate the ability to install a foundation and affect the performance of a foundation and therefore increase the cost of an offshore foundation. The goal of this research is to explore concepts ...

Random Vibration Theory (RVT) site response analysis is a standard in seismic hazard analysis for nuclear facilities to compute the dynamic response of soil deposits. However, studies have shown that the RVT analysis ...

Most practicing structural engineers are not well-equipped with the knowledge or tools necessary to adequately address the problem of alkali-silica reaction (ASR). While the mechanisms and consequences of ASR in plain, ...

Frontline supervisors (Foremen and General Foremen) are the first line of supervision and are an important link between the management and their construction crew (Uwakweh 2005). They play a significant role in maintaining ...
