Installation Of Electrical System For Paso Robles Police Department, Jacob M. Studebaker, Peter D. Strykers
Construction Management
This paper outlines the process that Peter Strykers and Jacob Studebaker went through to set up the lighting and power system for the Paso Robles Police Department gun range located off highway 46. Before our installation, the gun range had zero lighting so the officers could not use it after sunset. We allowed the officers to light the gun range with outdoor LED lights, light up both the storage units on site, and have access to multiple outlets inside and out of the storage units. The power source that the electrical system runs on comes from a Kubota generator because …

Digitalization Of Construction Project Requirements Using Natural Language Processing (Nlp) Techniques, Fahad Ul Hassan
All Dissertations
Contract documents are a critical legal component of a construction project that specify all wishes and expectations of the owner toward the design, construction, and handover of a project. A single contract package, especially of a design-build (DB) project, comprises hundreds of documents including thousands of requirements. Precise comprehension and management of the requirements are critical to ensure that all important explicit and implicit requirements of the project scope are captured, managed, and completed. Since requirements are mainly written in a natural human language, the current manual methods impose a significant burden on practitioners to process and restructure them into …

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

Optimizing The Self-Healing Efficiency Of Hydrogel Encapsulated Bacteria In Concrete, Ricardo Hungria
LSU Master's Theses
Calcium carbonate precipitation through microbial means is a promising pathway for concrete self-healing technologies, mainly for its microcrack sealing attributes. The main goal of this project was to study and optimize the crack healing efficiency of hydrogel encapsulated bacteria in concrete. To achieve this purpose, Bacillus pseudiformus was implemented as the bacteria strain at a concentration of 108 cells/ml. This bacterium strain along with yeast extract was combined along with three different mineral precursors corresponding to magnesium acetate, calcium lactate, and sodium lactate. All these three precursors were evaluated at two concentrations (67.76 mM/l and 75 mM/l). For each …
Reducing Early-Age Shrinkage Cracks Of Bridge Decks And Rails, Soumitra Das, George Morcous, Jiong Hu
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%).

Impacts Of Pandemic-Induced Material Price Escalation On Construction Estimation And Bidding, Chancellor G. Giessinger
Construction Management
The COVID-19 pandemic introduced new severe supply chain bottlenecks in the construction industry. These bottlenecks reduced the availability of a wide variety of critical construction materials, which created a scarcity that has raised material prices at an unprecedented rate and extended lead times for some materials by months. This poses new challenges for contractors with pressure from owners to deliver ongoing contracts with fixed, pre-pandemic contract pricing and for estimators seeking to bid new projects with unforeseeable future material pricing. The objective of this research to focus on contractors operating within the state of California and their primary challenges in …

Creating A Demolition Topic Course, Eli Jeremiah Lipton
Construction Management
Demolition is as old as construction itself and has always played an integral role in the construction process. That is, however, not the reality of the Construction Management (CM) program at California Polytechnic State University (Cal Poly). The current curriculum covers a wide range of topics and prepares students to be able to join any residential, commercial, and heavy civil projects. These projects all have something in common, the demolition process. Undergraduates are not prepared with the basic demolition knowledge to be successful in the industry. Demolition is overlooked at Cal Poly and is not a primary focus in any …
The Development And Evaluation Of A New Trench Safety Equipment, Joshua D. Clesi
The Development And Evaluation Of A New Trench Safety Equipment, Joshua D. Clesi
Construction Management
One of the most dangerous works in construction is trench work and excavation. Fatalities that range from permanent injuries to death happen to construction workers every day, not having a lot of alternatives to prevent unfortunate incidents such as cave-ins and shoring failures. What this paper is proposing is a new invention that may solve this ongoing problem with trench safety. The idea is a crane-like lift attached to the back of a pick-up truck that will vertically lift people out of the trenches in a matter of seconds before shoring collapses or the trench caves in. This project primarily …

Using Project Production Methodology To Compare Onsite Prefabrication Steel Erection To Traditional Stick-Built, Corinne R. Nalder
Construction Management
Project production management provides continuity, predictability, and optimization of a process in comparison to the traditional approach of project management. Prefabrication is an example of project production management in which there is continuity of the product, reduced variability, and where the assembly process can be altered for best results. This paper will examine the benefits of project production management and compare two methods of steel erection in which one method performs an onsite prefabrication process while the other method employs the traditional stick-built process. The two methods will be modeled by a tool that replicates a repetitive process similar to …
