High-Strength Concrete: Weighing the Benefits
Russell, Gebler and Whiting describe the properties of high-strength concretes, the current state of knowledge on freeze/thaw effects, and procedures for batching, mixing, transporting,...

Screaming Structures
As any designer of roller coasters will tell you, civil engineering principles put the thrills and screams into roller coasters. There are two basic differences between roller coaster...

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,...

Resilient Moduli of Soils
Laboratory Conditions
Historically, structural pavement design has been based on static testing techniques, such as the CBR. More recently, the profession has placed increased emphasis on repeated load testing...

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...

Knowledge-Based Construction Project Planning
This paper describes CONSTRUCTION PLANEX as a prototype of a knowledge-based construction process planner. CONSTRUCTION PLANEX is a knowledge-based system that generates project plans...

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...

An Integrated Project Control Model
This paper defines the scope of current project control activities and presents an overview of the tools used to control projects. Problems with current project control systems and the...

Integrating Voice Recognition Systems with the Collection of Project Control Data
The Construction Industry in the 1990's will be dominated by emphasis on Productivity, Competitiveness and Innovation. Success or failure in these areas lies in one word, Technology, and...

Project Control Via Acoustical Sensing
This paper describes ongoing research into automating the process of collecting project control information using acoustical sensing devices. The paper describes how frequency spectra...

The WMATA Resident Engineer and the METRO Construction Team
