Decision-Making for Cross-Laminated Timber Modular Construction Logistics Using Discrete-Event Simulation

Creator:: Abiri, Bahar
Abstract:: The two primary considerations for construction project management are budget and time management. Modular construction has the potential to improve construction productivity by minimizing time and costs while improving safety and quality. Cross-Laminated Timber (CLT) panels are beneficial for modular construction due to the high level of prefabrication, adequate dimensional...

Optimization of Construction Equipment Efficiency and Cost using Simulation and Field Data

Creator:: Kumar, Deepak
Abstract:: Unlike other industries, overall efficiency of construction projects has been growing minimally which directly causes cost overruns of projects. Though reducing idle time and increasing operational efficiency of construction equipment could result in significant cost saving, there is lack of practical knowledge of adjusting operational efficiency and integrating cost and...

Bridge Inspection Using Bridge Information Modeling (BrIM) and Unmanned Aerial Systems (UASs)

Creator:: Xu, Yiye
Abstract:: Bridge inspection is a critical task needed to monitor bridge quality and serviceability. In the U.S., 40% of bridges are more than 50 years old while most bridges are typically designed for a lifespan of 50 years. 9.1% of the 614,387 bridges across the U.S are considered structurally deficient. These...

A BIM-based Simulation Framework for Fire Evacuation Planning

Creator:: Sun, Qi
Abstract:: Fire hazards threaten human life and property safety. Since it is unrealistic to study human behavior during a real fire hazard, computational tools are a better choice to computational tools are a better choice to simulate fire growth and human behavior for predicting evacuation performance in chaotic emergency situations. Although...

Improving Safety on Construction Sites by Using Real Time Sensor Data to Monitor Worker Field-of-View and Proximity to Hazards and Reduce the Generation of False Positive Alarms

Creator:: Chan, Kelsey
Abstract:: The construction industry is infamously recognized for having jobsites identified as hazardous working environments due to workers-on-foot commonly functioning at dangerous heights and in close proximity to other construction entities, among other reasons. These hazardous operations result in an increased risk of worker injuries and fatalities caused by fall hazards...

Estimating Air Pollutant Emissions for Nonroad Equipment using EPA MOVES – Case Study of a Building Project

Creator:: Boddi Reddy, Sai Akhila
Abstract:: Total emissions from the US contribute 15% to the global emissions. The construction industry is a major source of the exhaust emissions produced. Use of light-duty vehicles and heavy-duty trucks for various construction activities contributes 83% to the total greenhouse gases produced. Construction equipment comprises of on-road and non-road equipment,...

Comprehensive Analysis of PM2.5 Pollution from Construction Activities

Creator:: Montadka, Nahush Prabhakar
Abstract:: The Construction industry is one of the most hazardous industries in the US.Construction workers, on a daily basis, are exposed to numerous risks while performing arange of activities involving construction, alteration, and or repair. Dust and diesel exhaustemissions from construction equipment are considered harmful to the workers in the longrun....

A Review of Current State Department of Transportation Practice for Promoting and Documenting the Safety of Field Employees

Creator:: Barlow, Zachary Wesley
Abstract:: State Departments of Transportation (DOTs) are the primary owners of roadway infrastructure in the United States. Many of the employees of state DOTs work on roadway work sites, putting them at disproportionately higher risks of injury or fatality. A review of the literature determined that a combination of policies, standards,...

Behavior of open grid steel bridge decks under service and fatigue loads

Creator:: Fetzer, Peter C.
Abstract:: Open grid steel bridge decks have been in use for nearly a century. These open grid decks provide an economical and lightweight alternative to traditional reinforced concrete decks. As the transportation infrastructure continues to deteriorate, open grid decks can be used as a cost effective way to rehabilitate structurally deficient...

Construction risks allocation : optimal risk allocation decision support model

Creator:: Alsalman, Ali Abdullah
Abstract:: It has been suggested that projects in the construction industry are subject to risks more than other industries. However, there is often little parity in allocation of risks in the construction industry. Usually, project participants allocate risks by aversion where owners tend to shift risks to the primary contractor, who...
