RISDetermining Highway Project Contract Time from Project Duration Estimates
Publisher: American Society of Civil Engineers
Abstract: Contract time determination (CTD) by state DOTs is critical to a typical design-bid-build project due to its profound impacts on stakeholders in various aspects, such as the actual amount of time allocated to the contractor, ...
Network Theory–Driven Construction Logic Knowledge Network: Process Modeling and Application in Highway Projects
Publisher: ASCE
Abstract: Determining a reasonable project duration is one of the most critical activities required by project owner agencies for successful project letting and delivery. Most owner agencies, specifically in the highway sector, ...
Pareto Principle in Scoping-Phase Cost Estimating: A Multiobjective Optimization Approach for Selecting and Applying Optimal Major Work Items
Publisher: ASCE
Abstract: Cost estimation is critical to a typical transportation project’s development process. Specifically, project owners use cost estimates during the scoping phase to set project budgets for funding approval and cost management. ...
Cost-Weighted TF-IDF: A Novel Approach for Measuring Highway Project Similarity Based on Pay Items’ Cost Composition and Term Frequency
Publisher: ASCE
Abstract: State highway agencies (SHAs) often need to cluster or bundle projects in accordance with their scope similarity for various construction management tasks, including historical data-driven time, cost estimating, and project ...
Sequential Machine Learning for Activity Sequence Prediction from Daily Work Report Data
Publisher: ASCE
Abstract: It is critical for project owners to have a reasonable estimation of project duration before the letting date for contract time determination and project management purposes. To determine the project duration, highway ...
Uncovering Critical Causes of Highway Work Zone Accidents Using Unsupervised Machine Learning and Social Network Analysis
Publisher: ASCE
Abstract: Highway work zones are essential for the preservation and improvement of the national road system. Nevertheless, these areas are reported to be among the most hazardous workplaces. Thus, it is crucial to develop appropriate ...
Network Theory–Based Approach to Data-Driven Assessment of Bidding Competition in Highway Construction
Publisher: ASCE
Abstract: Competitive bidding in design-bid-build contracts holds the potential to lower bid prices, maximize project outcomes, and promote growth in the construction industry. However, these potential benefits of competitive bidding ...
Discovering Workers’ Actions Leading to Severe Construction Accidents Using Accident Report Data and Sequence Mining Techniques
Publisher: American Society of Civil Engineers
Abstract: Historical construction accident reports have been widely used to gain insights into the primary causes of past incidents in construction. Previous studies have successfully identified accident causes and affected body ...
Geographic Information System–Based Framework for Estimating and Visualizing Unit Prices of Highway Work Items
Publisher: American Society of Civil Engineers
Abstract: Historical bid items from previous projects are an important source of data for project cost estimation. State highway agencies have widely used this data source for budget planning of highway projects. Current practices ...
Comprehensive Evaluation of Influential Factors on Public Roadway Project Contract Time
Publisher: ASCE
Abstract: Contract time determination (CTD) is one of the most critical activities when developing a public roadway. There is no lack of policy documents, process manuals, and technical papers emphasizing its significance and impact ...
