The estimation of construction duration is one of the most critical tasks in construction project planning, In the initial planning phase, however, estimating reliable project duration is an intractable problem. Since there are limited information and details in the preliminary planning, CBR(Case-Based Reasoning) can be considered as useful approach to solve this problem. Therefore this paper presents DEPOT(Duration Estimator for PrOjecT) as CBR-based construction duration estimating tool that is designed to estimate using available data at the early phase of project planning. DEPOT provides the similarity scatter diagram relating the similarity of past cases against the revised duration estimate and the list of similar cases to help retrieve a more optimal case for new construction project.
