  • Case-Based Reasoning
  • CBR
  • Cost Estimating
  • Abstract Cost estimating at the planning or preliminary design phase is usually performed by experienced estimators based on past experiences. However, domestic construction companies are relatively small in which frequent personnel turnover impedes transition of the experiences. This research attempts to solve the above problem by employing a case-based reasoning (CBR) technique into a computer system that comprises of 102 past construction cases. The input to the system is a set of building related parameters that include name of county, site area, floors above ground, floors below ground, gross floor area, exterior wall area, and perimeter of basement. The output of the system is a set of various costs for temporary construction, foundation, structure, exterior wall, rough interior, finishes, elevator, plumbing, and HVAC, etc. The CBR system provides construction rookies, the contractor as well as the owner a whole picture of the construction costs to facilitate the construction progress.
