11.H.3. PUBLIC WORKS: CR512 ROAD WIDENING/EXISTING UTILITY ADJUSTMENT - CR512 AND LOUISIANA AVENUE - WATER MAIN PROJECT CHANGE ORDER #1 - TREASURE COAST CONTRACTING, INC. The Board reviewed a Memorandum dated June 23, 1997: DATE: JUNE 23, 1997 TO: JAMES E. CHANDLER COUNTY ADMINISTRATOR FROM: JAMES W. DAVIS, P.E. INTERIM DIRECTOR OF UTILITY SERVICES PREPARED ROBERT 0. WISEMEN, P.E. Q�) AND STAFFED ENVIRONMENTAL ENGINEER TwW BY: DEPARTMENT OF UTILITY SERVICES SUBJECT: PUBLIC WORKS CR 512 ROAD WIDENING/MISTING UTILITY ADJUSTMENT CR 512 AND LOUISIANA AVENUE WATER MAIN PROJECT CHANGE ORDER NO. 1 INDIAN RIVER COUNTY PROJECT Nos. UW -95 -13 -DS AND UW -96 -17 -DS WIP NO. 472-000-169-264.00 AND ACCOUNT NO. 473-000-169-319.00 On May 6, 1997, the Board of County Commissioners approved and granted the construction of the water main projects to Treasure Coast Contracting, Inc. (i.e., CR 512 and Louisiana Avenue). The total approved construction cost was $405,269.00. During design of the Public Works road widening of the CR 512 project (eastbound), several conflicts between an existing sewer force main and proposed stormwater cross drains were identified. The staff proposed that the relocation of the sewer force main be performed by the contractor who was awarded the water main contract. Close coordination between the current Public Works contractor for the road project and our Utilities contractor already exists. Also, the Utilities contractor has already mobilized; therefore, he can most economically perform the work. ANALYSIS There are five. areas of conflict, which require relocation or adjustment of the existing force main. Four of the five conflict areas require construction of 45 degree fittings and restrainers. One conflict requires lowering approximately 100 feet of force main to avoid a stormwater cross drainpipe. The proposed change order negotiated by Utilities staff and submitted to the County for all of the conflict areas is in the amount of $12,232.00. This will adjust the contract cost to $417,501.00. This adjustment will not affect the Louisiana Avenue assessment project cost, as this relocation adjustment project will be temporarily funded through Account Nos. 472-000-169-264.00 and 473-000-169-319.00 (CR 512 water main) until a final reconciliatory accounting between water and sewer can be performed. RECO14 ENMTION The staff of the Department of Utility Services recommends approval of Change Order No. 1, which will adjust the contract amount to $417,501.00, and authorization of the chairman to execute same.
