Building market has been shortened for last few years and tremendously affected the construction profit in Taiwan. In order to survive in such abominable environment, people have put many efforts on construction methodology, materials, budget planning, and strategy alliance. However, to properly enhance the construction management is the key issue to raise company?s competition. Therefore, an effective administrating tool is a must in construction life cycle such as estimating, bidding, procurement, scheduling, site managing, and valuation. This research has utilized Object Oriented concept, E/R techniques and Delphi environment to develop the Construction Integrated Manage System (CIMS). Through the help of this tool, user can effectively generate Bidding List, Purchasing Materials, Labor and Material Analyze Items and Specifications. Basic Database System can help us to modify resource prices to adjust budget, effectively control project cost and financial planning. Budget Control System will inform engineers when overspend occurs. Purchasing System can assist us to select the best subcontractors with most reasoning price. Valuation system can extract money request data from site records; therefore, prevent the over-calculating and short-calculating to achieve a better financial administration. With the help of CIMS, we can effectively control all details such as bidding, purchasing, contracting and evaluating, for each construction stage. This integrated system can practically control all information, maximize construction management efforts, raise company?s strength, increase competition, and create profit for construction industry.
