Industry Perceptions On Public Sector Construction Delivery Methods, Evan Mccollough
Construction Management
The public construction sector in the United States has predominantly used the traditional delivery method, also known as design-bid-build, to obtain and deliver projects. Accurately assessing the direction of the public construction sector must include analysis of the emergence of Public-Private Partnerships (P3) and alternative delivery methods. P3 projects in the United States are relatively new, an emerging trend from the late 2000s as an innovative way to utilize private capital to finance public projects, beyond a typical bond sale. Alternative delivery methods refer to any project award or management arrangement other than the typical design-bid-build, lump sum, competitive bidding …

Initial Assessment Of Liquefied Scrap Tire Concrete, Abdulkareem Kuaryouti, Christopher D. Eamon
Civil and Environmental Engineering Faculty Research Publications
A new approach to incorporate scrap tire material into concrete was investigated, where two reclaimed waste tire components, carbon black and fuel oil, were used to replace a portion of water. The effect of “liquid tire” content to water ratios from 5-40% on an otherwise typical concrete mix were assessed, where compressive and flexural strength, flexural toughness, modulus of elasticity, and several fresh concrete properties were determined. Results were compared to typically expected results of traditional shredded tire mixes with equivalent tire content. It was found that the liquid tire mixes experienced significantly less losses of compressive strength and workability …

Multi-Skilled Labor Optimization With Partial Allocation Of Resources, Amira Saleh
Theses and Dissertations
The current practice of labor allocation in construction schedules assumes single-skilled workforce; meaning that each worker is assumed to be skilled in only one trade. In such practice, at any instance in the project lifecycle, some of the workforce become idle waiting for other labor types to complete their work. Traditionally, companies may relocate idle workers to other projects and return them back to their original project when needed again. This complicates the resource management process and is not often performed successfully, leading to schedule and cost overruns. Alternatively, project managers may keep the idle workforce at their projects because …

Using System Dynamics To Study The Effect Of Change Orders On Labor Productivity, Shrouk Gharib
Theses and Dissertations
Change orders in construction projects lead to numerous negative impacts, including loss of labor productivity, delays, and cost overruns. Owners and contractors are usually in disagreement when it comes to allocating the extent of responsibilities with respect to the resulting overruns. Each party tries to hold the other party fully responsible for such overruns through a series of claims and disputes. Several delay analysis techniques have been developed to aid in settling such disputes, however, they do not fully grasp the rippled impacts of change orders and do not assist parties in reaching consensus when it comes to finding the …
