Quantifying Uncertainty Of Construction Material Price Volatility Using Monte Carlo, Douglas D. Gransberg, Erin J. Kelly
Quantifying Uncertainty Of Construction Material Price Volatility Using Monte Carlo, Douglas D. Gransberg, Erin J. Kelly
Douglas D. Gransberg
This study uses Monte Carlo simulation to derive a quantitative measure of construction price volatility for two case study projects in Oklahoma. In the past four years, the impact of events like Hurricane Katrina and the economic growth in China have induced unprecedented volatility in US construction prices. This has caused a huge number of public construction project bids to exceed the owners' estimates, making it difficult for public construction agencies to be able to predict construction budgets. Construction prices are a function of many factors beyond pure material costs. This study broke down the pay items from a typical …

Preparing Cost Engineers For Today's Construction Industry Challenges, Kenneth Robson, Douglas D. Gransberg
Douglas D. Gransberg
Today's cost engineer must be comfortable working in the world of performance criteria rather than yesterday's legalistic prescriptive specifications. This requires a better understanding of the owner's requirements and a more responsive business approach. While these skills are certainly being acquired on the job by today's practicing cost engineers, it is incumbent upon university construction education programs to adjust the curriculum and ensure that entry-level cost engineers arc entering the industry with the educational background to quickly assimilate into this new, faster-paced environment. Thus, the purpose of this article is to describe how the University of Oklahoma's Construction Science program …
Developing Construction Claims For Arbitration: Two Arbitrators' Viewpoint, Douglas D. Gransberg, Charles A. Joplin
Developing Construction Claims For Arbitration: Two Arbitrators' Viewpoint, Douglas D. Gransberg, Charles A. Joplin
Douglas D. Gransberg
Two arbitrators' viewpoints of construction claims development are provided in the hope that the information will be useful to those needing to resolve construction claims by arbitration. It also may help to reduce the volume of costly and unnecessary documentation. Because of arbitration's relative formality, attorneys representing construction contractors and owners tend to prepare their cases in the same way as they would for litigation. This leads to potential information overkill, which threatens the arbitration panel's ability to easily sort through and understand the issues in its quest for a fair and equitable decision.
A Review Of Methods To Estimate Haul Fleet Production, Douglas D. Gransberg
A Review Of Methods To Estimate Haul Fleet Production, Douglas D. Gransberg
Douglas D. Gransberg
Five methods that are used to estimate haul fleet production based on optimal analysis are reviewed. The results predicted by those methods are compared to actual field observations. The results of the comparison are used to recommend various methods for estimating haul fleet production. The 5 methods were authored by: 1. R. L. Peurifoy, as interpreted by Atcheson, 2. F. H. Griffis, 3. M. Gates and A. Scarpa, 4. R. E. Phelps and 5. J. J. Adrian and L. T. Boyer. Atcheson's method is generally conservative, which is not necessarily in this application. The Phelps method seemed to be the …
