Betting on the Baseline (Available in Geoenvironmental Special Issue only)
In construction contracts, new deductive differing site conditions (DSC) clauses provide for credits to owners when contractors encounter better-than-anticipated subsurface conditions....
Into the Fourth Dimension
A team of contractors designed a pharmaceutical plant entirely in 3-D CAD, then linked the renderings to a cost program and scheduling software, adding a fourth dimension�time�to the process....
The Warranty Alternative
State highway agencies are investigating such alternative contracting methods as warranties in reaction to decreased budgets and resources. The advantages to warranty contracting include...
Roughness Coefficients in Manning's Equation as an Estimating Tool for Bankfull Discharge in Natural Channels
(No paper) This paper compares the results of Annable's work to the roughness coefficients by stream type given in Rosgen (1994) as well as some additional coefficients from the eastern...
Stepwise Flood Routing for Gated Reservoirs and Conjunctive Optimization of Hydroelectricity Income with Flood Losses
A six-stage operation policy for routing of flood hydrographs of return periods from 1.01 year up to the Probable Maximum Flood (PMF) for dams having gated spillways is suggested. The...
Dynamic Groundwater Remediation Design with Genetic Algorithms
In groundwater remediation design it has been shown that dynamic policies, in which the pumping strategies may vary throughout the remediation period, can result in more cost-effective...
Simplification of Detailed Models of Water Distribution Systems Obtained from GIS Systems
For a long time simplified models have been used to simulate the behaviour of large water distribution networks. Often, simplification has been carried out by removing small diameter pipes...
Friction Factor Choice in Hydraulic Simulation Models: Does It Matter?
(no paper) To model water distribution systems using computer hydraulic simulation, a user is required to select a form of head loss-flow relationship for each pipe in the network. The...
Sensitivity of Stormwater Conveyance System Cost to Design Recurrence Interval
(No paper) The cost of a piped and/or swaled stormwater system is determined principally by the storm recurrence interval (e.g., 5-year design storm) used to design it. That is, the present...
Community Participation in the FEMA FIS Process: A New Way to Go
(No paper) As an experienced FEMA Study Contractor (SC), there are numerous items of interest that the community could participate in to facilitate the Flood Insurance Study (FIS) process....
A Leadtime Driven Flood Warning Response Plan Design
(No paper) The paper examines the optimal combination of predictive and detective capabilities in the development of the Wickenburg Flood Response Plan and extrapolates those findings...
Stream Stability and Scour at Highway Bridges
Compendium of Stream Stability and Scour Papers Presented at Conferences Sponsored by the Water Resources Engineering (Hydraulics) Division of the American Society of Civil Engineers
Sponsored by the Water Resources Engineering (Hydraulics) Division of ASCE. This collection contains 75 papers and 321 abstracts presented at conferences...
Everybody Wins
A program sponsored by the Department of Defense (DOD) allows small firms to team up with larger ones in a mentoring-prot�g� relationship that helps both gain more defense contracts. Mentors...
Managing the Megaproject
The Mon/Fayette Expressway and Southern Beltway will link Pittsburgh, Pennsylvania and Morgantown, West Virginia via a 104 km, $3.5 billion Y-shaped highway. With the project split into...
All Eyes on I-15
The largest single highway construction contract in United States history is currently underway in Salt Lake City, Utah. The Utah Department of Transportation's innovative...
Preparing Specifications for Design-Bid Build Projects
The Committee on Specifications of the Construction Division of ASCE has developed a guide to preparing construction specifications for design-bid build projects. The guide contains preparation...

When the Levee Inflates
Rubber dams�long, flexible tubes, anchored to a concrete base and abutments and inflated with air or water�have been used since the 1950s, but installations have risen as technology has...
Realizing Engineer-Led Design/Build
While design/build's popularity has grown this decade, the notion that engineers and architects cannot manage the project has remained. Typically heavily capitalized contractors...
Rapid Redecking
A contractor replaced nearly 7,000 m� of steel grid roadway deck filled with microsilica concrete on the Canadian crossing of the Thousand Islands bridge system more than one year ahead...
