Conservation Before and After: The Impacts of Increasing Block Rates on a Fully Metered System
Denver Water's inside residential consumption and revenues changed dramatically during a metering program and a conversion to inclining block rates. We analyze these two changes and make...

WATSUP: A Simulation Model for Water Supply Cost and Reliability
WATSUP (Water Supply) is a computer model developed to provide a prototype modeling tool for planners to estimate the costs and reliability of urban water supply systems on a regional...

Evaluating the Steady State Stochastic Dynamic Programming Model for the High Aswan Dam
The paper describes the results of a study to critically evaluate and test the Steady State Stochastic Dynamic Programming model (SSDP). Whenever a reservoir computer model is developed,...

Wet Detention Facility Pollutant Removal Modeling
This paper documents development of the WETPOND model, which simulates long-term pollutant removal by a wet detention facility. Pollutant removal is determined with an EPA procedure that...

Reliability Analysis of a Multi-Reservoir Water Distribution System
A methodology for evaluating system reliability is developed to assist in the planning and management of a multi-reservoir water distribution system. The minimum cut-set approach is employed...

Summer Engineering Outreach Program for Native Americans
Minorities are significantly underrepresented in engineering, science and math fields in the United States. To attract and retain capable minority students will require the development...

A Salmon Population Model for Evaluating Alternative Flow Regimes
Salmon populations in many Pacific coast rivers are in decline and in danger of becoming threatened or endangered. A fish population model that tracks chinook salmon from eggs to the immature...

The Job-Order Contracting Solution
A new method of contracting, Job Order Contracting, combines many contracts into one administered by one project team. They are competitively bid, indefinite delivery, indefinite quantity,...

A New Angle on Ground-Water Remediation
When engineers from Black & Veatch Waste Science (BVWS) went to Tinker Air Force Base to examine the site of a hazardous waste cleanup job the service had hired them for, they...

Multimedia in Civil Engineering
Multimedia inspires so many claims and hype that it can be hard for engineers to figure out what's real and what's not. The truth is that multimedia holds great...

Graphical-Based Productivity Transient Investigation Using DISCO
Construction operations involve complex resource interactions and are typically performed in the field with exogenous factors such as inclement weather conditions and equipment breakdowns....

An Integrated Approach To Repetitive Construction Planning
Repetitive construction projects are unsuited for the use of the Critical Path Method (CPM) for their scheduling. Statistical simulation techniques offer a scheduling alternative, but...

Quantification of Cost Uncertainties Using Neural Network Technique
This paper describes the development of a neural network system for forecasting cost escalation in construction. The input of the neural network system consists of factors that have an...

Interpretive and Modelling Problems of Risk and Uncertainty in Bidding Techniques
This paper considers the implementation of policy, strategic and tactical bidding and the processes of devolution of the risk and uncertainty in a corporate management context....

Circle Integration
Based on the results of proof-of-concept experiments, we propose that an integrated suite of software tools can support both automation and integration of several components of AEC design...

Startplan: Producing Schedule Templates Using IRMA
The Information Reference Model for AEC (IRMA) is a generic information modeling standard to support computer-integrated construction (CIC). Although IRMA is still in a conceptual stage,...

Functional Analysis of the Envelope Design Process for Integrated Building Design
Building envelope failures account for a great portion of building failures. The number of envelope deficiencies would be reduced if the design process was integrated. Integration would...

Construction Problem Solving in a Cooperative Distributed Agent Environment
This paper outlines the research being undertaken by the authors to determine how experts develop solutions to construction problems in a cooperative distributed agent environment which...

Improved Computer Simulation of 3D Wind Flow Around a Building
A two-layer method combining the k-? model with the one-equation model near the wall has been tested in computing the wind conditions around a cubic building. In contrast with the simple...

Different Methods to Compute Pollutant Dispersion Around Buildings
Different methods to approximate the advection terms currently in use are reviewed. Holly-Preismann (HP) cubic interpolation using method of characteristics, Chapeau function (CF) method...
