Metal Building Systems: A New Look
The use of metal building systems in low-rise, non-residential construction under 150,000 square feet has grown from less than 50 percent in 1986 to almost 70 percent today. Such systems...
Resolution Solutions
Disputes over such issues as change orders, extra work, delays, or defective work are an inescapable part of the construction process. By designing an effective dispute management program...
Application of Linear Programming Techniques to Optimize Groundwater Withdrawals for a Pump and Treat System at Aberdeen Proving Ground, Maryland
The U.S. Army disposed chemical agents, laboratory materials, and unexploded ordnance at the O-Field landfill from before World War II until at least the 1950s. Soil, ground water, surface...
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...
Integration of SWMM and ARCVIEW GIS for Interactive Decision Support
(No paper) This paper covers the integration of the EPA SWMM runoff model and ESRI's ArcView GIS for utilization by the City of Phoenix for decision support concerning land use changes...
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...
