Organizing for Effective Project Management
Effective project management is an essential element in any engineering project. This paper traces through the planning, preliminary engineering, fixed design, bidding, construction, testing...
St. Louis Transit Alternatives Analysis?Project Management and Organization
Improving public transit service has been a long standing goal in the St. Louis region. An alternatives analysis of the region's priority transit corridor was completed in...
Organization for Rapid Transit Design and Construction
This paper discusses organizational arrangements for design and construction of rapid rail transit systems and the advantages and disadvantages of the various organizational arrangements....
Rail Transit Construction Readiness: The Evolving MARTA Organization
A rail transit project is a complex undertaking involving thousands of people, expending millions of dollars and ultimately taking years to accomplish. The Metropolitan Atlanta Rapid Transit...
Managing Quality into the Workplace
In February, 1983, the author's organization began a process designed to enhance attitudes about quality in every individual member of the organization. The process requires...
Modeling Streamflow Response from Minnesota Peatlands
A deterministic, continuous simulation model was developed to predict the effects of peatland development on streamflow. The Peatland Hydrologic Impact Model is largely physically based...
Permanence of Chemically Grouted Sands
Test specimens were prepared with one of three uniformly graded sands of a fine gravel and injected with one of five silicate or two polyacrylic grouts. The polyacrylic grouts showed no...
Chemical Grout Curtains at Ox Mountain Dams
Grout curtains were constructed in granodiorite bedrock as part of two earthfill diversion dams at a sanitary landfill site on the San Francisco, California peninsula. The curtains are...
Acoustic Emission Monitoring of Grout Movement
This paper describes the acoustic emission (AE) method in general, and in particular the AE system which holds significant promise in this regard. Used was a multichannel AE system which...
Grout Slurries?Thick or Thin?
In this paper some recent experiences in dam grouting in several countries are discussed where bentonite or Intraplast additives were used to control sedimentation, viscosity, grout density,...
Municipal Refuse: Is Burning Best?
Communities are increasingly worried about polluting groundwater, and it is increasingly difficult to get permits to start new landfills. For these reasons, there is a trend back to municipal...
Checking Off CADD Priorities
Diving head on into new computer aided design and drafting (CADD) hardware and software without considering their effects on firm or university's operation is as bad as ignoring...
Construction QA/QC Systems that Work
Case Studies
Four case studies discuss the issue of responsibility for quality assurance and quality control by describing actual situations where quality work is being done in the field. The case...
Organization and Management of Public Transport Projects
Transit development projects are undertaken to help satisfy escalating transportation needs in modern cities. The projects address an array of technical, social, and environmental considerations....
Two Dimensional Numerical Simulation of Subsurface Contamination by Organic Compounds - A Multiple Approach
In recent years, much attention has been focused on the migration of the soluble portion of an organic contaminant in groundwater systems. Little work, however, has been directed towards...
Development of a State Information Clearinghouse
The University of Virginia is conducting a study on the feasibility of establishing the Virginia Water Resources Information System (VWRIS). Objectives of the study are: 1) Documenting...
Groundwater Models in Choosing Water Treatment Methods
This paper presents an example of the use of groundwater models to identify the source of contamination and then design a treatment scheme. Included is a discussion of several different...
Predicting Areas of Groundwater Contamination
Logistic regression has been used to estimate the probability that a metropolitan area will contain one or more water supply sites with contamination by one or more of six frequently occurring...
Enhanced Mobility of Polynuclear Aromatic Compounds in Soil Systems
The objective of this study was to determine adsorption isotherms for polynuclear aromatic (PNA) compounds in methanol and a mixture of 50 percent methanol 50 percent water. The adsorption...
A Modified RBC Design: Performance Evaluation
An RBC (rotating biological contactor) system was designed using Pall rings type 40, and tested under high organic surface conditions. Influent soluble BOD averaged at 55 mg/l, equivalent...
