Building a Team, Not Just a Building
The best way to resolve construction disputes is to head them off. And the best time to step in is before your contractor is hired. In the private sector, there is no reason to open the...
Multiple Presence Reduction Factors for Bridges
This paper reviews the multiple presence reduction factors specified in the AASHTO and Ontario codes, and provides a method by which these factors can be established in relation to volume...
Long-Range Forecasts of Water-Supplies
Many engineers and water-users have an urgent need for reliable predictions of future rainfall and water supplies, extending many months or years ahead. Correlation of known historic rainfall...
Comparison of TRC 212 and SR 209 LOS Calculations
With the release in 1985 of Transportation Research Board (TRB) Special Report (SR) 209, numerous traffic engineering agencies began the transition to new methods of calculating capacity...
Considerations in Applying the 1985 HCM Procedures
The paper examines the impact of critical assumptions in the 1985 Highway Capacity Manual (HCM) procedures on the resulting measures of effectiveness -- volume/capacity ratio, delay, and...
Estimating Future Traffic Volumes at the Intersection Level
This paper uses the experience gained on a number of regional and sub-area studies in the northeast to illustrate how measured and forecast traffic information can be combined to predict...
Trip Table Estimation from Observed Traffic Volumes
This estimation technique identifies the most likely trip table to produce a specified set of traffic counts when assigned to a representative highway network. The resultant table is derived...
Response of Great Salt Lake to Climate Variability
Levels of Great Salt Lake, Utah, have fluctuated through a range of 6. 2 m in the historic record since the 1840s. In water years 1983-1984, the lake rose 2. 9 m in response to record...
Estimating Climate Change From Hydrologic Response
In the eighty-one hydrographically closed basins within Nevada many large lakes developed during the pluvial climate of the Pleistocene. Pluvial lake area and tributary basin area have...
Issues in Specifying Climate Forcing of Variability
Several issues arise in the specification of the role of climatic forcing of variability of water resources. The effects of human intervention must be removed so that the climate signal...
Stochastic Design of Wastewater Storage Ponds
The authors combine the principle of mass conservation with basic ideas from probability theory and then apply Monte Carlo simulation techniques to develop a family of design charts called...
Use of In Situ Tests in Geotechnical Engineering
In the past ten years, many new types of in situ test equipment and many new techniques have been developed. The papers in this volume are concerned with applications of in situ measurement...
The Training of the Owner
Engineers would do well to explain to their clients just what the role of the engineer is. The place to start is with one's ability to produce a perfect set of plans. Imperfections...
Procurement of New Passenger Rail Cars from Japan
In May 1983 the California Department of Transportation (Caltrans) signed a contract with Sumitomo Corporation of America, in which Sumitomo agreed to furnish 63 new stainless steel gallery...
Timber Bridge Decks
The portion of the nation's 500,000 bridge decks that are made of timber has been declining for years, as the old timber ones on secondary road bridges are rebuilt, in most...
Holding Down the Cost of Change
The most significant element in reducing the cost of contractual and project changes is the resident engineer and how he and his staff handle those changes. As discussed in this paper,...
The Resident Engineer
In this paper, the author defines the resident engineer's (RE) role based on his experiences. His illustrations of the RE as engineer, interpreter, issuer of change orders,...
Cost Engineering for Disputed Work
Engineers and architects tend to underestimate the cost of disputed work, especially those connected with delay. The engineer, using industry standards and estimating rules of thumb, can...
Application of the Federal Highway Administration (FHWA) Micro-Computer Based Quick Response System (QRS) Software to the Analysis of a 200 and 400 Acre Comprehensive Plan Change From Residential to High Tech Land-Use
The purpose of this study was to identify major changes in traffic volumes and generally the transportation implications caused by changing the Comprehensive Plan on a large area in the...
Electronic Traffic Management
High technology has entered the world of traffic and transportation management with such new optical and electronic devices as transponders, retro-reflective stickers, microprocessors,...
