Abstract: A productivity model has been developed that provides the average construction firm with the means of measuring, predicting, and improving a given method's productivity. The mode, referred to as the Method Productivity Delay Model (MPDM) focuses on method productivity parameters that are measurable and controllable by the average construction firm. Method productivity parameters are addressed by documenting productivity delay. The model recognizes the environment and constraints of the average construction firm, requires only simple mathematics, and is compatible with existing union work rules. The MPDM evolved from considering the positive attributes of existing models, from considerations of contractors viewpoints, and from experience of observing construction methods and method productivity. The model possesses all of the attributes necessary to provide the average construction firm with the means of measuring, predicting, and improving productivity. Its use can often provide dollar benefits exceeding its cost of implementation.
