Lump Sum Estimating: Discovery and SimulationStatus: CompleteReport Date: 06/11/2012 Summary: Researchers evaluated the cost-effectiveness of changing from a unit pricing to a lump sum bidding process by comparing these methods with respect to total bid amount, time necessary for inspection, and the attitudes of contractors and MnDOT personnel. Results showed that the lump sum process is viable and produces similar bid results as the traditional process. Using lump sum bidding would require an improvement in the accuracy of construction plans as well as new guidance and training for inspectors whose responsibilities would shift from tracking quantities to performing quality control and assurance.
