RISSpatial Distributions and Stochastic Parameter Influences on SWAT Flow and Sediment Predictions
Publisher: American Society of Civil Engineers
Abstract: The Soil and Water Assessment Tool (SWAT) was implemented in Northwest Arkansas to investigate flow and sediment predictive ability at multiple subbasin and hydrologic response units (HRU) distributions. The objectives of ...
Temporal Effect of Construction Workforce Physical Strain on Diminishing Marginal Productivity at the Task Level
Publisher: American Society of Civil Engineers
Abstract: Physiological status and environmental stressors are known to influence workforce performance at the individual worker level. A previous study, which conducted a cross-sectional comparison in repetitive material-handling ...
Contractual Battles for Higher Ground: Case Examples
Publisher: American Society of Civil Engineers
Empirical Comparison of Methods for Estimating Location Cost Adjustments Factors
Publisher: American Society of Civil Engineers
Abstract: Location factors are used to adjust conceptual cost estimates by project location. Presently, the construction industry has adopted a simple, proximity-based interpolation method to estimate location factors for missing ...
Procurement of Design-Build Services: Two-Phase Selection for Highway Projects
Publisher: American Society of Civil Engineers
Abstract: In the United States, public agencies are adopting the design-build (DB) delivery method for delivering highway projects after having used the traditional design-bid-build method for generations. In the 2002 design-build ...
Study of the Relationship between Procurement Duration and Project Performance in Design-Build Projects: Comparison between Water/Wastewater and Transportation Sectors
Publisher: American Society of Civil Engineers
Abstract: Previous studies on building, industrial, and transportation projects found that projects delivered using design-build tend to perform better than projects delivered with the traditional design-bid-build method. However, ...
Exploring the Influence of System Quality, Information Quality, and External Service on BIM User Satisfaction
Publisher: American Society of Civil Engineers
Abstract: Over the past decade, architecture, engineering and construction (AEC) companies around the world implemented building information modeling (BIM) to enhance their firms’ competitiveness and readjust their business processes. ...
Data Fusion of Real-Time Location Sensing and Physiological Status Monitoring for Ergonomics Analysis of Construction Workers
Publisher: American Society of Civil Engineers
Abstract: Previous research and applications in construction resource optimization have focused on tracking the location of material and equipment. There is a lack of studies on remote monitoring for improving safety and health of ...
Design Management in Design-Build Megaprojects: SR 99 Bored Tunnel Case Study
Publisher: American Society of Civil Engineers
Abstract: The increasing use of the design-build project delivery method has resulted in it now being one of the most popular nontraditional methods for delivering road, bridge, mass transit, and rail projects in the United States. ...
Empirical Assessment of Spatial Prediction Methods for Location Cost-Adjustment Factors
Publisher: American Society of Civil Engineers
Abstract: In the feasibility stage of a project, location cost-adjustment factors (LCAFs) are commonly used to perform quick order-of-magnitude estimates. Nowadays, numerous LCAF data sets are available in North America, but they ...
