DMG explains the added need for the motor grader for minor grading of the backfilled areas. While this is a reasonable use of the equipment such use would still fall well within the 25% use currently assessed for the grader. Very little time is needed for road maintenance by a grader for jobs performed by scrapers. We were assuming that the bulk of the 25% utilization would be applied to the minor regrading function and not road maintenance. BME maintains the position the DMG should modify the CIRCES program to allow one operator to operate several pieces of equipment up to a maximum of 100% utilization. We recognize that such changes will probably not be completed for this round of cost estimation. However, it should be completed by the next software update. BME brought up this shortfall in the software during the last midterm review and nothing has been done to address this issue. l0. Dozer Push Gradients (sediment pond reclamation) When regrading an embankment on relatively flat ground material is not pushed `5rp and over" the embankment. Material is first removed from the top of the embankment and pushed down onto the sides of the pond area. There is no case where material would need to be pushed "up and over" an embankment since the top of the embankment needs to be moved to complete the project. The drainages where the dams are constructed have a very low gradient, only 1 or 2%. As such, only a very small portion of the material at the very lower toe of the fill would have to be pushed up. The bulk would actually be pushed down into the reservoir. Thus, our request to use a "0%" push gradient instead of a 5% uphill gradient is reasonable. 11. Demolition Costs a. Concrete Demolition DMG's response was "See attached Unit Cost Menu and associated Unit Cost Calculation Table-Concrete building, concrete floor demolition, concrete wall demolition, and RCP (reinforced concrete pipe) demolition." However, the referenced material was not attached to the response. Please provide this information to help clear up questions conceming cost estimates for concrete demolition. b. Footing Demolition DMG's response was "See attached Unit Cost Menu and associated Unit Cost Calculation Table-Concrete footer demolition."
