This structure was not shown on the plans, since it was not of record and its existence was unknown. Removal of this abandoned vault was required in order for the storm drain and appurten- ant facilities to be installed in accordance with the plans and specifications. Two water mains were also broken by the Contractor during excavation. These mains were not shown on the plans since the serving utility was not aware of their existence. The Contractor was compelled to shut down his entire crew, consisting of 6 personnel and 4 pieces of equipment, for a hour. Payment to the Contractor will be made on a time and materials basis, for removal of the vault and shut down time. The total estimated project cost, based upon the actual low bid price, contained an mount of $28,918 for contingencies, which will be used to finance the cost of this change order. We recommend Change Order No.1 be approved. 75.0264 yr")ject: Seccombe Lake Storm Drain'Lateral f-lan No. 6769 Date: 1-17-86 File No. 4.424 ENGINEERING DIVISION DEPARTMENT OF PUBLIC WORKS CITY OF SAN BERNAnDINO, CALIFORNIA CONTRACT CHANGE ORDER NO. ~ (Change necessitated because of field conditions) Kershaw Construction Company P.
