Lessons Learned from First Impulse Turbine Installation in the U.S. Mining Industry
The paper discusses a research study to recover energy from service or cooling water brought into deep mines. The test site was the Luck Friday Mine, owned and operated by the Hecla Mining...
Sedimentation of Waste Particles in Coastal Waters
Environmental effects associated with various ocean disposal practices are determined to a large extent by the fate of waste particles. The importance of coagulation on particle deposition...
Simulation of Evaporation Ponds for Liquid Waste Disposal
A computer model for designing and simulation of evaporation ponds is developed. It is based on the principle of mass conservation for water, for the total dissolved solids (TDS), and...
Learning from Failures: Procedural Changes in the Design and Construction Process to Reduce Failures
This paper first defines failures and their number and scope in the design and construction fields. It then presents the writer's opinion as to the cause of the failures and...
The Resident Engineer?A Member of the Construction Team
The paper discusses the prime concern of a resident engineer, namely, seeing to it that the structure built is in accordance with the plans and specifications and that the work is carried...
Ensuring Quality Construction
This paper describes the US Army Corps of Engineers' efforts at procuring quality construction: 1) a three-phase approach (preparatory, initial, follow-up) was developed to...
Construction Scheduling for Public Sector Projects
The paper presents some types of scheduling systems that are utilized in Postal Service projects as well as the advantages and disadvantages of each. It is suggested that schedule approval...
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's Role in Multiple Contracts
This paper addresses the role of the Resident Engineer who functions either as a General, Electrical, Mechanical or Mechanization Engineer in multiple prime construction contracts. By...
Development of a Resident Engineer
The author discusses a development program suitable for a Resident Engineer to take up. Included in the requirements of the program are actual experiences, training courses and personal...
Hazardous Waste Cleanup: The Preliminaries
Court-ordered negotiations rather than a trial took five years but led to a flexible plan for cleaning up an inactive hazardous waste disposal site in Niagara Falls, N.Y. Contamination...
Danger: Natural System Modeled by Computer
Computer (mathematical) models are written to simulate such natural systems as those leading to acid rain, flooding, or toxic waste migration from disposal sites into groundwater. In some...
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...
Changing Priorities in UK Construction Research
This paper addresses two types of situations to contend with in building assessment: aging structures all built at about the same time and to standards no longer acceptable, and newer...
Environmental Engineering
The purpose of the annual Conference on environmental engineering is to pursue scientific knowledge and promote sound engineering judgement and practice in the solution of environmental...
Earthquake Experience Data on Power and Industrial Structures: Applications to Seismic Design and Evaluation
An extensive study was conducted to document the seismic performance of typical power plant and industrial structures in selected recent strong earthquakes and to correlate the performance...
Micro/Mini/Maxi?Hardware or Software, Or, What's the Future??What's the Answer?
Current research is developing new materials, producing more sophisticated circuits, allowing price reductions, linking micros and minis to mainframes. The next technological avalanche...
The Transit Industry Microcomputer Exchange Support Center
The Transit Industry Microcomputer Exchange Support Center has been in existence for nearly three years. This paper describes the reasons for establishing the center, its current activities,...
Fracture Problems in the Transportation Industry
Six cases of damage tolerance assessment are presented, involving structures or vehicles in the U.S. transportation industry. Damage tolerance means arranging design, maintenance, and...
Seismic Experience Data?Nuclear and Other Plants
