a r � TO: Honorable Members of DATE: August 25, 1982 FILE: Indian River County Board of Commissioners THROUGH: Michael Wright, County Administrator SUBJECT: Change Order No. 7 to Pebble Bay Wastewater System Improvements FROM: George Liner REFERENCES: ti pJJG 1082 Utilities Manager - c� rG:�t a of s wee DESCRIPTION AND CONDITIONS: The contract was originally bid to have the gravity main jacked and bored under AlA in the vicinity of the Vera Cruz lift station. In the process of installing the new lift station, it was decided by the con- tractor that it is too difficult (if not impossible) to jack and bore the gravity main because of conflict with -other utilities such as the lift station, Vero Beach water main, and telephone cables. Permission and regulations for open cut were obtained from Florida DOT to make the open cut. This comprises traffic control, backfill densities, and repaving to.DOT specification. These negotiations, meetings, discussions, and permits have taken some time. The contractor has requested an extension of 7 days to the contract for the delays in obtaining the commission approval for this change order. - ALTERNATIVES AND ANALYSIS: The choice of an alternative is moot since the open cut installation of pipe is the alternative. Normally, to jack and bore cost more than open cut for pipe installation. In*this case, it is felt that the regulations .of DOT will result in negligible savings. This contract work has much that remains to be done by the completion. date of August 30, 1982. The commission meeting of September 1, 1982, at which this change is requested for approval is after the presently contracted completion date. Therefore, it is appropriate that a - - scheduYed extension -be granted for completion of the open cut work. RECOMMENDED AND FUNDING: A figure was negotiated with Bain Underground, Inc. for time and materials not to exceed $3,500.00. This is the figure used for the bid to jack and bore under AIA. Therefore, there will be no additional cost to the county resulting from this change order. It is recommended that the commission approve Change Order No. 7 on a time and material basis not to exceed $3,500.00 This change order should be accompanied by a,one week extension of the contract. ON MOTION by Commissioner Lyons, SECONDED by Commissioner Bird, the Board unanimously accepted the recommendation of staff to approve Change Order No.. 7, not to exceed $3,500. v" I�"„.�147 t�
