Central Artery (I-93)/Tunnel (I-90) Project
This paper is intended to provide an overview of the Boston Central Artery/Tunnel Project (CA/T) Project; a $4.9 billion USD interstate highway constructed underground through a densely...
Seismic Design Issues for Immersed Tube Tunnels
This paper provides an overview of the issues and the state of the art techniques in the seismic design of immersed tube tunnels (ITT). Particular focus is given to the ITT presently planned...
Computer-Integrated Construction and the Building Life Cycle
This presentation will discuss the computer-integrated construction (CIC) movement, where this movement is heading, how current CIC software products meet the needs of today's...
The Impact of User Interfaces on CAD Systems
The generation of architectural layouts through knowledge-based techniques forms a notable focus in design research efforts. A significant aspect of this research centers upon the development...
Integration of CAD and Material Control
The purpose of this paper is to address the relationship between CAD (Computer Aided Design) drawings and the material control software. Computer generated drawings have the ability to...
3-D Positioning for Construction Surveying and Automation
Three-dimensional real-time positioning is a critical requirement to allow for improved surveying and autonomous vehicle control. Given such a system and a project data link, multiple...
Designing Plans for Constructability
The writer has obtained several years experience acting as construction engineer for roadway rehabilitation projects as a consulting engineer. In this capacity, it is necessary to provide...
Constructability?Washington State Highways
During the last decade, efforts were directed towards improving constructability of highway design at Washington State Department of Transportation (WSDOT). This paper briefly summarizes...
Time/Cost Bidding
This paper presents the details of a relatively new and innovative approach to determining the low bidder on highway construction contracts. In the cost and time method each bidder proposes...
Negotiations: How do You Measure Success?
Negotiating a 'successful' outcome once a dispute has arisen is often more difficult than negotiating agreement prior to the emergence of conflict. The basic...
Kinematics and Trajectory Planning for Robotic Excavation
One of the high volume and repetitive construction operations at the construction site is the excavation of soil. Automation of the excavation work requires a robotic system that is able...
State and Local Issues in Transportation of Hazardous Waste Materials
Towards a National Strategy
This proceedings contains papers presented at the specialty conference State and Local Issues in Transportation of Hazardous Materials: Towards a National Strategy held on May 14-16, 1990...
Building Green
Some scientists say polystyrene insulation may be responsible for up to 40% of the ozone depletion caused by CFCs. That's only one reason why construction and design professionals...
Ductile Frames Are Tough for Earthquakes
Implications of a new structural system in wharf design go far beyond San Francisco Bay, where two such wharves remained intact after the 1989 Loma Prieta quake. The design, introduced...
Air-Water Transfer: The Role of Partitioning
A review is presented of the role of air-water equilibrium in determining the direction and rate of transfer of chemicals between water bodies and the atmosphere. Because this diffusive...

Lysimeters for Evapotranspiration and Environmental Measurements
Lysimeters have been used extensively in the past to provide baseline information for development, calibration, and validation of evapotranspiration methods. This proceedings,
Avoiding Defective Specifications
Despite everyone's best efforts, the design intent as portrayed in the contract documents is rarely crystal clear. As a result, the owner and the project team often find themselves...
Update: Bridge Scour
Nearly 500 bridges have failed because of hydraulic conditions�primarily scour�since 1950, but the collapse of the Route 90 bridge over Schoharie Creek in April 1987 focused national attention...
Rehabbing the U.S.
When it comes to protecting its $1.4 trillion investment in public-works infrastructure, the U.S. has been like a homeowner who puts off fixing a leak until the ceiling lands on his head....
