This project repaired the failed portions, and placed the final H" of the design structural section. The riding qualities deteriorated significantly, rehabilitation of the pavement. of Hospitality Lane which necessitated had the The existing soil beneath the pavement on Hospitality Lane was found to be excessively wet in several areas, due to leaking water and irrigation lines. The existing subgrade could not be compacted, as required by the specifications, in order to carry traffic loads. In order to stabilize the subgrade and bridge over the saturated material below, 2 feet of unsuitable material was excavated, and a geo grid stabilization mat was laid. o Change Order No. Five authorizes the Contractor to ex- cavate the unsuitable material and lay the mat in a 1600 square yard area, on a time and material basis, at an additional cost of $7,665.22. The total estimated project estimate, based upon the actual low bid price, included an amount of $23,036.25 for contingencies, which can be used to finance the cost of this change order. All work under this contract, including the change orders, was satisfactorily completed as of 2-28-89. Change Orders No. One and Two authorized the installation of a 12" pipeline for water from Gage Canal wells. Change Orders Nos. Three and Four authorized the replacement of failed section of curb and gutter and installation of a conduit to serve a relocated street light. The conduit was installed under this contract since it would be less expensive, than coming back later after the street was paved. The contract was awarded for the low bid price of $150,263.75. Change Orders One through Five increased the contract price to $186,592.47. The actual final contract price is $182,081.10, due to a lesser quantity of repairing street cuts actually being done than the estimated quantity in the bid documents. o Tri-City Corporation, Gage Canal Company and the City of Riverside are funding two-thirds of the cost of Change Orders No. One and Two. Therefore, the final cost to the City is $163,994.43, leaving a balance of $9,305.57 (or 40%) remaining in the contingency funds. 5-02-89 75.0264 - CITY OF SAN BER&DINO - RIEQUEST ~R COUNCIL ACTION o STAFF REPORT Page 2 of 2 We recommend that the work be approved and accepted, and that final payment be authorized at the expiration of the lien period, and Change Order No. 5 approved. o c 5-02-89 75-0264 -", .II 11 Project: Pl."
