Implicit Design Knowledge and its Impact on Cost Estimating
Construction cost estimating experiences negative impacts due to a design-construction gap created by the fragmented nature of the AEC industry. Most of the design knowledge and data that...
Conceptual Model for a Site Operations Control System
This study discusses a conceptual model for designing an on-site management control system. Capabilities of this proposed Site Operations Control System (SOCS) include a mechanism for...
3D Computer Modeling & Animation for Marketing of Project Services
Three-dimensional (3D) computer modeling and animation are increasingly being utilized in the Engineering and Construction industry for the marketing of project services. Like 2D, 3D modeling...
An Object-Oriented Simulation System for Construction Process Planning
This paper presents an object-oriented simulation system designed to integrate specific construction knowledge into construction process planning. Using the object-oriented representation,...
Site Layout: Where Should it Go?
Site layout is mostly treated as a task independent of other resource allocation tasks such as those that are traditionally associated with construction planning and scheduling. Yet, the...
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...
Integrated Cost and Schedule Control Automation
Effective management of construction projects depends on good access to and control of data, especially data pertaining to cost and schedule control functions. Long recognizing the need...
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...
Turbulent Water Aeration: Analytical Approach and Experimental Data
Analytical studies based on the statistical theory of turbulence were carried out in order to identify some relevant parameters which may be associated with the reaeration rate coefficient...
Methane Tracer Technique for Gas Transfer at Hydraulic Structures
Using a simple headspace gas chromatographic technique, gas transfer at several hydraulic structures were investigated. Naturally occurring methane was used as a tracer gas to measure...
Gas Transfer at Hydraulic Structures
The objective of this paper is to identify and briefly summarize the state-of-the-art in measuring and describing gas transfer at hydraulic structures. Basic theory of mass transfer at...
A Simple Empirical Model of Aeration at Navigation Dams
In a study of aeration at 28 dams in the upper Ohio River basin, site-specific least-squares linear regression models were used to describe the dissolved oxygen deficit below each dam...
Oxygen Transfer at Spillways
A relationship for oxygen transfer efficiency, E, at spillways and gated spillways with a hydraulic jump or plunge pool, has been developed from conceptual considerations and fit to measurements...
Theoretical Investigation of Oxygenating Bubble Plumes
Rehabilitation of lakes by oxygenation with air or oxygen plumes has been proven to be biologically feasible. Oxygenating plumes are released from areal sources and the gases are absorbed...
Water Surface Flow and Exchange Induced by a Bubble Plume
Aeration is a common method to increase dissolved oxygen in the water of stratified (or non-stratified) lakes. In this method compressed air is injected at some depth, and gas is transferred...
Steady Turbulent Gas Desorption in Surface Condenser Tubes
A one-dimensional steady two-phase separated flow model in conjunction with the energy and mass transfer equations and an associated turbulent mass transfer coefficient model are utilized...
