Computer-based Large-scale Construction Project Health Diagnosis System

Abstract

A computer-based Large-scale Construction Project Health Diagnosis System (LCPHDS) was developed under the direction of diagnosis theory which is based on scientific evidence for diagnosing implementation status in construction projects. First, a brief introduction was given into diagnosis thought in medicine field; then, the health diagnosis theory was illustrated from four aspects of how to extract characteristics and relevant parameter variables, how to build a system of indexes and relevant weights, how to provide a set of judgment standards as references and how to illustrate the process of diagnostic computations. Programming technologies and developing tools like C#, SQL Server 2005 and C/S architecture were elaborated for a better understanding of the development environment of LCPHDS. In the end, the user interface (UI) and functional performance were demonstrated to exhibit the wholeness of the system. LCPHDS mainly helps managers or directors to analyze and supervise implementation status, especially quality, over the life-cycle. The proposed system has already been implemented by a construction company in Guangzhou for a trial run, and has made some effects.
