Existing U.S. Standards in Hydraulic Engineering
The Task Committee on Recommendations for Standards in Hydraulics confined itself to topics that are used in hydraulic computations or design. Thus numerous standards related to size,...

An Integrated Model for Fate and Transport of Oil in Rivers
An integrated oil spill model for microcomputers is developed for simulating fate and transport of spilled oil in rivers. This model can simulate the oil slick transformation in transient...

Numerical Model Development for Oil Spill Dispersion into the Marine Environment
A 3-D oil spill model was developed to study the behaviour of heavy spilled oil in the sea. The model could describe the behaviour on the spilled oil on the sea surface, throughout the...

A Study of Friction Factor for Flow in Gravel Bed Channels
For many years practicing engineers have faced the problem of predicting the resistance to flow in channels with rough surface. Flow in channel is a complex interaction between surface...

Calibration of Beni-Mazar Movable Bed Model
A sand-bed model representing a reach of the Nile River was constructed to study alternative solutions to maintaining the navigation channel. Flume tests were carried out first to determine...

Development of Standards for Slipform & Jumpform Works
Review of past work indicates substantial effort has been made to publish construction standards and guidelines for slipforms but published material pertaining to jumpforms is scarce....

Temporary Structures for Protection and Access
Temporary Structures in Construction Projects (TSC) are utilized for three (3) purposes A. Support (of the structure being built or adjacent structures or utilities) B. Protection (of...

Composite Twin Tub Bridge Erection Intersection of Interstate I-84 and I-94 in Hartford, Connecticut
Curved bridge erection requires detailed preparation by the contractor, plus a sharing of responsibility and liability between the owner, designer of the new structure and the contractor....

Who Pays for the Unexpected in Construction
The problem of who pays for the unexpected in construction is discussed in relation to the testing and inspection of construction materials. Laboratory is often blamed for poor construction...

Construction Product Performance, The Unexpected
Efforts made in the construction, industry to increase the quality of the constructed facility through the development of new materials and systems and through the reduction of labor intensive...

The Virtual Design Team: An Object-Oriented Model of Information Sharing in Project Design Teams
The Virtual Design Team (VDT) is an object-oriented, discrete event simulation of a multidisciplinary design team in action. The VDT models a design task as a network of design and design...

Computer Data Exchange Using National and International Standards
There is a need within the construction industry to electronically transmit standard documents between designers, owners, contractors, and material suppliers. Ideally, the transmission...

Construction Inspection Responsibility from the Viewpoint of a General Contractor and Construction Manager on a GMP Project
Absent local laws to the contrary, any member of the construction team, the Owner, Architect, or Contractor, can theoretically arrange for and provide any testing and inspection that may...

Construction Technology/Method Identification and Selection System
The proliferation of construction technology and the characteristics of technology information, such as complexity, interdependency, etc., pose the need for a well-organized technology...

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...

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...

Future Fill-Up
The car rental agencies at Phoenix Sky Harbor Airport have combined their service/filling facilities in the new terminal's parking garage. This permits customers to pick up...

Designing Better Hollow Fibre Contactors
In this paper we calculate optimum hollow fibre module designs for gas absorption by maximizing the mass transferred per unit cost. Two costs are considered; the membrane cost and the...

The Soil-Rock Boundary: What is it and Where is it?
A major issue in many areas of Civil Engineering practice is the boundary between earth materials that are defined as soil and those that are defined as rock. Designers, contractors, and...

Problems with Rock Excavation Specification in Alberta
As a result of contract overruns and claims from classification, measurement, and payment for 'solid rock' excavation, Alberta Transportation and Utilities embarked...
