Computer Methods Used on Seismic Retrofit Projects
Over a relatively short period of about twenty years, personal computers (PC's) have replaced slide rules in most engineering calculations. PC's are now staple equipment in every engineering...

Developing an Integrated Database Structure for the Lifecycle of Precast Concrete Projects
This paper presents an integrated database structure for the storage and retrieval of information during the planning, design, manufacturing and construction of a structural precast concrete...

Modeling Facility Engineering Processes & Data Using the P-C Approach
A facility engineering process typically involves participants from different disciplines, several life-cycle phases, and many computer applications. In this paper, we propose the Primitive-Composite...

An Automated Database System for Construction Bidding
A number of probability-based bidding models have been developed to assist a contractor in preparing bids that improve chances of winning over the competition. Models based on utility...

Adaptive, Multi-Resolution Modeling of Construction Plans
The process of developing a construction plan is complex, taking many considerations and constraints into account. In contrast, the CPM paradigm of planning allows only the results of...

An Effective Estimate of the Percentage Completion of Construction Projects and Concomitant Progress Payments
This paper will discuss the methods of assistance to contractors in visualizing the effects of variations in the quantities of their work and how to obtain such information effectively....

Filing of Construction Photos Linked with Database
In order to raise the added value of construction information, a filing system of construction pictures is built up and is used theoretically linked with a database. Here, conditions set...

GIS Applications in Urban Roadway Management Systems
The urban roadway network is a major component of any municipal infrastructure system. Effective management with systems methodology can greatly increase the service life of these facilities...

Design Information Hierarchy for Construction Method Selection Process
The Construction Project Planning (CPP) stage is a critical stage for the success of a construction project. This stage lays the framework upon which most of the construction decisions...
