International Airport Terminal Finance: ', Council Notes: 75-0262 Agenda Item No. CITY OF SAN BERNARDINO - REQUEST FOR COUNCIL ACTION STAFF REPORT Page 1 of 2 The plans for improving the access roads and parking lot to serve the passenger terminals, for the San Bernardino Trade Center and International Airport, direct the installation of a 42-inch storm drain in Leland Norton Drive. Upon commencing excavation for this storm drain, the Contractor encountered numerous obstructions that were not discovered during a record search by the Consulting Design Engi- neer and were, therefore, not shown on the plans. It was required for three water lines to be relocated, to allow the new storm drain to be installed. Due to the many ob- structions encountered, the Contractor was directed to dig a pilot trench along Leland Norton Drive to locate utility facilities crossing the street. These items of extra work were done on a time and material basis, in accordance with Section 3 of the Standard Specifications, at an estimated cost of $19 , 856 . 40 . About 200 feet of the 42-inch storm drain had to be removed and re-installed, due to the trench being flooded when a valve for the irrigation system was inadvertently opened. The storm drain alignment had to be adjusted at 3 locations where it was in conflict with a concrete encased 33-KVA electrical duct. These items of extra work were done on a time and materials basis, at an estimated cost of $6 , 461 . 02 . Portions of concrete encased 10-KVA electrical ducts had to be removed at 7 locations , in order to allow the 42-inch storm drain to be installed in accordance with the plans. Also, these ducts had to be removed at 3 locations where they were in conflict with the storm drain laterals . The Contractor' s forces were delayed while these removals were being done. The items of extra work were done on a time and materials basis , at an esti- mated cost of $16 , 463 . 70 . The Contractor' s forces were precluded from working during the times that utility facilities in conflict were being removed or relocated. This lost time is considered a right-of- way delay in the Standard Specifications, and amounted to $5 , 087 . 19 (which represents 1/2 of actual rental rates) . About 300 feet of 6-inch conduit, service panel, and electrical cables were installed, in order to provide service to the pump station for the remediation effort, after the existing vaults are abandoned. This extra work was done on a time and material basis, at the agreed upon price of $17 , 580 . 00 . The plans direct the Contractor to adjust 5 existing electrical vaults to the new grade. 4-24-96 75-0264 CITY OF SAN BERNARDINO - REQUEST FOR COUNCIL ACTION STAFF REPORT Page 2 of 2 Installation of the 300 feet of 6-inch conduit, as described above, will allow these vaults to be abandoned. Therefore, adjusting these vaults to grade can be deleted from the contract, for an agreed upon credit of ($25 , 000 . 00) . The plans direct the Contractor to adjust an estimated amount of 5 existing telephone vaults to the new grade. It has been determined that these vaults can be abandoned, which will allow the adjusting to grade to be deleted from the contract, at an agreed upon credit of $1 , 500 each, or ($7 ,500 . 00) . One combined electrical/telephone vault can also be abandoned, which will allow adjustment of this structure to the new grade to be deleted from the contract, at an agreed upon credit of ($7 , 500 . 00) . Funds to finance the net additional costs authorized by Change Order No. Two will be provided from the following sources : Economic Development Administration Grant - 750 Inland Valley Development Agency - 250 All costs incurred will be charged to Account No. 242- 362-5504-7038 , and billed to the grant and IVDA. No City funds will be used to finance any portion of the additional costs . We recommend that Change Order No. Two be approved. 4-24-96 FEDERAL PROJECT NO. 07-49-02680.01 CONTRACT CHANGE ORDER CHANGE ORDER NO. 2 DATE: 4/17f96 Agreement Date: 2/12f96 NAME OF PROJECT: PASSENGER TERMINAL ACCESS ROADS AND PARKING FACILITIES; SAN BERNARDINO INTERNATIONAL AIRPORT OWNER: CITY OF SAN BERNARDINO CONTRACTOR: RIVERSIDE CONSTRUCTION The following extra work is to be performed, as directed by the Resident Engineer, and the following changes are hereby made to the CONTRACT DOCUMENTS: (1) Relocation of 3-existing 12-inch water mainlines in conflict with the new 42-inch storm drain, and excavating a pilot trench for locating unmarked utility lines on Harry Sheppard and Leland Norton prior to the installation of the new 12-inch water mainline, on a time and material basis, at a total cost of $ 19,856.40. (2) Pull out and relay 42-inch storm drain pipe that was misaligned due to irrigation water flooding the trench, and perform work to realign the pipeline at three locations where a conflict with an existing 33 KVA concrete duct prevented the installation of the storm drain as indicated on the plans, on a time and material basis, at a total cost of $ 6,461.02 . (3) Removal of 7-existing 10 KVA and telephone concrete encased ducts in direct conflict with the new 42-inch storm drain, and 3-existing 10 KVA concrete encasement in conflict with the installation of the storm drain laterals, and lost production time in the initial excavation of the storm drain mainline and lateral trenches, on a time and material basis, at a total cost of $ 16,463 .70 . Page 1 Contract Change Order No. 2 07-49-02680 .01 (4) Right-of Way Delay due to work stoppage during remediate of the utility conflicts in the installation of the 42-inch storm drain mainline, at a total cost of $ 5,087 . 19 .

JUSTIFICATION: During the installation of the new storm drain system, numerous obstructions were discovered that resulted in a delay in the installation of the new storm drain system, these included concrete encased electrical and telephone ducts, existing water mainlines, as well as misc. utilities that were in direct conflict with the installation of the new storm drain system. Some such as the 33 RVA electrical transmission ducts could not be moved so the storm drain pipe had to be removed and relayed in order to clear the line, water lines had to be either caped off or adjusted to clear the storm drain, additionally, on three occasions the storm drain pipe needed to be removed and reinstalled due to the flooding of the trench that occurred as a result of caretaker personnels unauthorized opening up water gate valves on three occasions which flooded the trench and resulted in sections of the storm drain pipe being removed and reinstalled. Since it was obvious that there were many potential obstructions that affected the installation of the storm drain system, it was decided that a pilot trench would be dug prior to the installation of the new water mainline. As a Page 2 Contract Change Order No. 2 07-49-02680.01 result, 30 obstructions were discovered in direct conflict at the location and elevation where the new waterline was to be installed, however, since this condition was known on the onset, the contractor was able to make the adjustments to the elevation of the new waterline prior to the installation, avoiding all of the obstructions. What would have been a costly delay and resulted in additional work and extra costs was prevented, and the only additional costs incurred were for the excavation of the pilot trench. There was an additional cost of the installation of a service to the existing pump and treat plant on Rialto Avenue, installation an electrical service to this location will enable the abandonment of many of the existing electrical and telephone vaults.
