FOR COUNCIL ACT )N STAFF REPORT Durinq excavation for construction of the storm drain several conflicts with utility facilities were encountered, These conflicts were a result of the facilities not beinq in the locations shown on the records provided by the utility companies, Adjustments were required from the planned aliqnment of the storm drain which necessi- tated the Contractor to perform the extra items of work described below, Four concrete collars were required to provide watertiqht pipe aliqnment was adjusted to clear utility facilities, a unit price of $500 each for these collars. joints, where the 48-inch The Contractor has quoted The contractor ordered specially made bevelled joints to allow the pipe to be in- stalled on a curve, However, it was not possible to use these bevelled joints, due to the adjustments required in the alignment to clear utilities, Regular 60-inch joints of reinforced concrete pipe were used, which necessitated the con- struction of 3 concrete collars, The bid schedule in the original contract included construction of 3 60-inch concrete collars at a unit price of $1,000 each, However, the Contractor quoted a price of $900 each for these 3 additional concrete collars, A catch basin was constructed on the north side of Fourth Street, east of Sierra Way, under this contract. After construction of this catch basin was completed, it was discovered that the street pavement was not installed on a grade that would direct storm water to this facility, Installation of 25 tons of asphalt concrete was required to achieve the proper drainage pattern, The Contractor quoted a price of $25,00 per ton for installing this asphalt concrete, The r,ontractor had to pay a restocking charge for the 6 lengths of the special bevelled 60-inch pipe, Since the restocking charge levied by the pipe manufacturer was due to circumstances beyond the Contractor's control, a claim for this fee has been submitted to the City, The installation of IS supports for sewer laterals was included in the contract, However, 7 additional sewer laterals were encountered that were not of record, Seven additional supports were required to protect the sewer laterals not shown on the plans, The Contractor has agreed to install these 7 additional suoports at the contract unit price of $100 each, The total estimated project cost, based upon the actual low bid price, contained an amount of $28,918 for contingencies, The total of Change Order No, 1 and 2 is $10,120,09, We have reviewed the prices quoted by the Contractor and feel they are fair and reasonable, Therefore, we recommend that Change Order No, 2 be approved. 75-0264 fr0jec' S e c co 1111lC' L ,\ k eSt lll'ld [) I' . n L ,\ t e r ill Date: 1-31-[;" Yl~n No, (,/G 9 F il e No, ~ .
