Book Synopsis Model Development for Cost-plus-time Bidding Applied to Florida Department of Transportation Highway Construction by : Jin-Fang Shr
Download or read book Model Development for Cost-plus-time Bidding Applied to Florida Department of Transportation Highway Construction written by Jin-Fang Shr and published by . This book was released on 1999 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, most SHAs and contractors use traditional methods. However, more exact time estimates and closer cost predictions are necessary to enable the use of these innovative methods. This research will explore the following topics. For the Florida Department of Transportation (FDOT) (1) how to determine a reasonable range of B in an A + B contract, and (2) how to determine a maximum incentive and maximum days of incentive in an I/D contract. For contractors interested in FDOT projects, (1) what is the best strategy to determine a bid price in an I/D contract, and (2) what is the best strategy to determine a bid price using an A + B + I/D contract. Data from the Florida Department of Transportation (FDOT) are used to verify models to respond to the topics above.

Book Synopsis The Impact of Change Orders on Mechanical Construction Labor Efficiency by : Paul Joseph Vandenberg
Download or read book The Impact of Change Orders on Mechanical Construction Labor Efficiency written by Paul Joseph Vandenberg and published by . This book was released on 1996 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Change orders impact many areas of construction projects. However, the impacts that change orders have on labor efficiency are much harder to quantify and are, therefore, a significant risk to contractors. Little research has been completed in the past quantifying these impacts so that disputes are common between owners and contractors regarding the actual cost of change. This study uses data from 43 projects, 27 impacted by changes and 16 not impacted by changes, to develop a linear regression model that predicts the impact on labor efficiency. The input factors needed for the model are: (1) Total Actual Project Hours, (2) Total Estimated Change Hours, (3) Impact Classification, and (4) Timing of Change. Timing of Change is calculated by breaking the project schedule down into six periods (i.e., changes before construction start, 0 - 20%, 20 - 40%, 40 - 60%A, 60 - 80%, and 80 - 100%), listing the percentage of change that occurred in each period, and calculating a weighted timing factor. The model calculates the labor loss or gain in efficiency for a particular project so that owners and contractors will better understand the true change impact on labor efficiency. Significant results have been found in hypothesis testing. The results show that impacted projects have larger amounts of change, have a larger decrease in labor efficiency, and are more impacted by change that occurs later in the project schedule. These results appear to be consistent with the intuitive judgement of industry professionals. The research is limited to the mechanical trade, but does include specific work in plumbing, HVAC, process piping, and fire protection.

Book Synopsis CPM Schedule Density by : Jeffery L. Ottesen
Download or read book CPM Schedule Density written by Jeffery L. Ottesen and published by . This book was released on 2019 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation addresses construction labor trade stacking, which oftentimes creates adverse labor inefficiencies, delay and cost overruns on construction projects. Present industry practice holds that Critical Path Methodology (CPM) scheduling is more accurate with resource loading assigned to construction activities, and that likelihood for trade stacking is reduced when managing a resource-loaded schedule. However, despite the potential benefits, and for many reasons, most contractors choose not to resource load their schedules. This research sought to create a predictive model for construction labor productivity loss using non-resource loaded CPM schedules as the primary input. This research advanced under a primary assumption that regardless of whether a contractor utilizes resource loading or not, the contractor will allocate enough daily resources to a scheduled activity so that that activity will be completed within its planned duration. This assumption is captured in a new metric called a Crew Day Resource (CDR). When planned schedule activities overlap in time, trade stacking occurs and the number of CDR's for that day likewise increases. Schedule density refers to the increasing degree of overlapping activities in a CPM schedule. How that density measure changes from schedule update to update allowed a predictive mathematical model to be created with strong correlation between the schedule density and actual observed labor productivity. Five construction projects were evaluated with emphasis on specific trades including mechanical and electrical work on three high rise buildings, large bore piping on a power plant, and structural steel work on a marine maintenance structure. Results of this research are encouraging and justify expansion of the project sample size, particularly for mechanical and electrical trades in high rise building projects. Additionally, this study provides the basis for development of a project management tool that may alert managers of potential construction labor inefficiencies before they occur.
