The RCP pipe needed to be removed in order for the contractor to continue to remove and replace the sewer main. The removal of the concrete and RCP pipe required the use of a breaker and required contractor to haul excess concrete and RCP pipe to the dump. The approximately six (6) hours of labor and equipment represents the additional hours over what would have been required to remove the existing sewer main by itself. Cost Reconciliation This change in the contract was reviewed and negotiated by and between the City Representatives and the Contractor and represents the entire agreement for the work described herein and includes all costs associated with the work including but not limited to manpower, equipment, labor, fees, taxes, insurance, bonding, overhead, profit, etc. and there will be no other compensation.
