Using Cost Simulation And Computer Vision To Inform Probabilistic Cost Estimates, Shu Jing Ding Apr 2022

Using Cost Simulation And Computer Vision To Inform Probabilistic Cost Estimates, Shu Jing Ding

Department of Construction Engineering and Management: Dissertations, Theses, and Student Research

Cost estimating is a critical task in the construction process. Building cost estimates using historical data from previously performed projects have long been recognized as one of the better methods to generate precise construction bids. However, the cost and productivity data are typically gathered at the summary level for cost-control purposes. The possible ranges of production rates and costs associated with the construction activities lack accuracy and comprehensiveness. In turn, the robustness of cost estimates is minimal. Thus, this study proposes exploring a range of cost and productivity data to better inform potential outcomes of cost estimates by using probabilistic …

A Case Study Of Protecting Bridges Against Overheight Vehicles, Aly Mousaad Aly, Marc Hoffmann Apr 2022

A Case Study Of Protecting Bridges Against Overheight Vehicles, Aly Mousaad Aly, Marc Hoffmann

Faculty Publications

Most transportation departments have recognized and developed procedures to address the ever-increasing weights of trucks traveling on bridges in service today. Transportation agencies also recognize the issues with overheight vehicles’ collisions with bridges, but few stakeholders have definitive countermeasures. Bridges are becoming more vulnerable to collisions from overheight vehicles. The exact response under lateral impact force is difficult to predict. In this paper, nonlinear impact analysis shows that the degree of deformation recorded through the modeling of the unprotected vehicle-girder model provides realistic results compared to the observation from the US-61 bridge overheight vehicle impact. The predicted displacements are 0.229 …

Analyzing Resource Allocation And Levelling In Construction Projects, Mohamed Eizeldin, Mohamed Hussein Hegazy, Ahmed Alhady, Shahir Ashraf Apr 2022

Analyzing Resource Allocation And Levelling In Construction Projects, Mohamed Eizeldin, Mohamed Hussein Hegazy, Ahmed Alhady, Shahir Ashraf

Civil Engineering

Project scheduling has been crucial in any construction project since applying poor scheduling may lead to cost overruns and delays. The most commonly used technique for scheduling is the critical path method (CPM). As CPM neglects the availability of resources and assumes only time as a constrain; therefore, the resource allocation problem (RAP) technique is introduced. RAP appears when the number of resources required exceeds the number of resources available. Moreover, as a result of solving the RAP, another problem will occur known as the resource leveling problem (RLP). RLP lead to lots of hiring and firing of laborers. Researchers …

Reducing Early-Age Shrinkage Cracks Of Bridge Decks And Rails, Soumitra Das, George Morcous, Jiong Hu Apr 2022

Reducing Early-Age Shrinkage Cracks Of Bridge Decks And Rails, Soumitra Das, George Morcous, Jiong Hu

UNL Student Research Days Posters, Graduate

Early-age shrinkage cracking of concrete bridge decks and rails accelerates the penetration of water and chemicals which leads to reinforcement corrosion, delamination, and eventually spalling. All this results in shorter service life, road closure, and costly repair. Development of Low-cement concrete(LCC) mix to reduce early age shrinkage crack through aggregate grading optimization was done in this research work. This approach also reduces concrete cost ($15-$20/cyd) (15–25%) and its carbon footprint (≈15%).

Investigation Into Engineering Change Order Costs And Appropriate Rules-Of-Thumb, Kaiana M. Miller Mar 2022

Investigation Into Engineering Change Order Costs And Appropriate Rules-Of-Thumb, Kaiana M. Miller

Theses and Dissertations

Engineering Change Orders (ECO) are technical requirements changes to existing contracts. To account for the potential increase in contract costs stemming from ECOs, current acquisition practice is to estimate a dollar value to hold in management reserve (MR) in case of ECO occurrence. Estimators often rely on rules-of-thumb when developing these estimates. Specifically, estimators use a 10% rule-of-thumb for estimating MR contract costs in the Development life cycle phase and a 5% rule-of-thumb for contracts in the Production or O&S life cycle phase. However, no empirical data supports or validates these 10% and 5% figures. Using a new data source, …
