Correlation Between Cost Growth and Procurement Methods on USACE Construction Projects
Procurement methods play a major role in the outcome of a construction project. This study focuses on the various procurement methods that are commonly used throughout the United States Army Corps of Engineers (USACE) and analyzes each for construction cost growth. It also describes each method in detail. In order to determine which procurement method performs the best regarding construction cost growth, the study used both quantitative and qualitative data. The quantitative data was taken from project data (procurement method, cost growth, time growth, etc.) from three different resident offices in two different districts. The qualitative data was developed from interviews of 13 different resident engineers in nine different districts. The result of both types of data is that acquisition methods which award construction contracts considering other factors besides low cost, such as Best Value Tradeoff and Sole Source, perform significantly better when it comes to controlling cost growth. This study determined that taking into account factors such as past performance of contractors and best value were key in controlling cost growth on USACE construction projects, as opposed to awarding contracts to the lowest bidder.
Approach for Easy Management of Bid Invitations in Construction: A Web-Based Application
Lack of communication between general contractors and subcontractors is often seen as one the major reasons for time delays and cost overruns in construction projects. This communication issue extends and is seen in the bidding process during preconstruction phase of a project as well. Oftentimes during bid days, contractors are seen struggling with the way in which they track bid invites and gather the intentions of subcontractors regarding bidding. This leads to a lot of manual work, a huge amount of time, and often strained relationships between general contractors and subcontractors. This paper presents the development and evaluation of a web-based computer application, which provides an easy platform for general contractors to send and manage their bid invitations. The paper also guides through the process of app development in detail which requires no manual coding and is accomplished using a simple database tool called Knack.
Risk Management in Alternative Project Delivery Scenarios: A Construction Manager/General Contractor Case Study
The Construction Manager/General Contractor project delivery method is a relatively new approach for contracting public infrastructure projects in America. While added later to the Federal Highway Administration (FHWA) SEP-14 program to investigate innovative contracting methods, State Departments of Transportation are only now beginning to more widely adopt this methodology. This paper analyzes a case study project to relocate Highway 53 in Saint Louis County, MN—a Minnesota Department of Transportation (MnDOT) project that is one of only a handful of federally funded projects to have been completed under this project delivery method. Based upon firsthand experience, key project participant interviews, and construction document analysis, the authors detail the procedures and processes used to leverage contractor experience/knowledge in order to minimize project risks and use project funding more efficiently.
