This research focuses on developing an integrated information
management system for construction site data management. Site
data collection and management is a daily and major construction
management task that can either enhance or adversely affect
construction efficiency. An effective site data management with
the aid of computer technology can not & 櫏 reduce the
repetitive works for data input, but also improve the
construction productivity. In the development of the system,
two major aspects of information management are concerned,
namely management of construction site data and data integration
of cost estimates with progress payment measuring.For
construction information management, the site data framework and
procedures for passing the data are identified using data flow
diagram and structural database analysis. Eleven system
functional modules including budget preparation, contract
administration, design drawings management, bidding and award,
personnel management, construction records, construction daily
reports, schedule controls, cost controls, measuring progress
payment, and change orders are developed for site management.
Integrating estimating data with progress payment measuring is
applied in this study to reduce the repetitive works for
quantity calculation. Traditionally, the detailed estimates is
conducted based on the detail design to calculate a careful
tabulation of all the quantities of the project. This research
creates a new way of thinking by integrating the graphical
features of detail design with the related estimating
quantities. The integrated information is used in construction
phase for measuring the progress payments. Using GIS, the
quantities of completed works can be input to the daily reports
by selecting the related graphic features and then, the monthly
or semimonthly payment quantities are obtained by summarizing
the daily reports. Moreover, the construction progress can be
represented in graphics with different colors.
