Hydro on Hold
Hydropower projects have become the target of a growing environmental movement overseas. The tradeoff between clean, renewable energy and the possible environmental impacts of the reservoirs...
Water Beneath the City Streets
Urban groundwater control requires high levels of skill and experience but allows for only a small margin of error. Determining the best method for controlling groundwater requires knowing...
National Water Conference
This book contains papers presented at the ASCE National Water Conference held at the University of Delaware, Newark, DE, July 17-20, 1989. The National Water Conference was cosponsored...
Post-Audits of Environmental Programs and Projects
This is the proceedings of a session at the ASCE Convention, New Orleans, October 1989. Post-audits include evaluation, assessment, and audit of the effects, both intended and unintended,...
Building Commissioning
In order to detect and correct defects in a timely, cost effective manner, HVAC system commissioning has recently been used as part of building construction. Preliminary evidence suggests...
An Effective Cost Control System
Project budgeting consists of converting the capital cost estimate into accountable cost centers by physical or process area and classifications of work. The primary purpose of the project...
The Cost of Quality: A Management Tool
In design and construction of engineered facilities, the cost of quality is a major cost item; perhaps exceeding one fourth the total installed project cost. A simple, flexible Quality...
Reflections on Design of a Turnkey Hydro-Power Project?Calaveras, California
Developing the Calaveras project under a turnkey agreement has shown that: (1) some 2 years can be saved, (2) cash flow for the owner is significantly delayed, because engineering is first...
Integrated Automation for Site Work
Technologically, computer integration can be built around four component systems; (a) a computer system to maintain unified data and control real-time operations, (b) a metrology system...
Automated Position and Control Systems Using Lasers and Electromagnetic Signals
Positioning is a crucial area in the successful integration of CAD data into the construction process. This paper looks at several areas of positioning using lasers and electromagnetic...
High Speed Multi-Link Automated Control
A new manipulator control technique is being investigated with potential for improving equipment life and productivity without requiring more operator training. It can retrofit to multi-link...
Real-time Monitoring of Heavy Equipment in Open Pit Mines
This paper reports on a system with local intelligence to interpret on-board signals. Existing sensors, pressure switches, warning lights, relays, and on-board monitoring systems provide...
Change Orders & Claims?An Owner's Perspective
Generally, the changes come before the claims. The owner wants to know why a change is needed, how much it will cost, and why the need for it was only just discovered. More money spent...
A Model for Construction Quality and Productivity
A set of necessary and sufficient conditions for construction quality is developed. Numerical simulations are then performed to evaluate the effectiveness of various quality improvement...
Contracting for Quality Facilities
Currently, Department of Defense (DoD) contracting for facilities is done almost exclusively with sealed-bid solicitations, low-bid awards, and firm-fixed-price (FFP) contracts. Quality...
