OR COUNCIL ACTION STAFF REPORT During construction, an underground concrete cut-off wall was encountered, within the County Flood Control District's right-of-way. The County had not revealed the existence of this structure during review of the project plans. Removal of the structure was required, in order to allow for construction of the box culvert. As the extent of the work could not be determined, the Contractor removed the structure on a time and material basis, as provided in Section 3-3, Extra Work, of the Standard Specifica- tions, at an additional cost of $6,766.21. Additionally, existing drains from the adjacent property were necessarily extended under this new sidewalk, at an additional cost of $451.78. Two County Flood Control cable barriers were also relocated for a total net cost of $500.00. We recommend that Change Order No. TWO be approved, authorizing this extra work for a total increase in contract price of $7,717.99, from $248,079.77 to $255,797.76. The total estimated project cost contains sufficient contingencies to fund the additional cost incurred for this change order. All work was satisfactorily completed as of 2-26-90. The contract was awarded for the low bid price of $244,404.77. Change Order No. One was approved authorizing the Contractor to install a catch basin and pipe at the intersection of Northpark Boulevard and University Avenue. Change Order No. One increased the contract price by $3,675.00, from $244,404.77 to $248,079.77. Change Order No. Two will increase the contract price by $7,717.99, to $255,797.76. The actual final contract price is $255,676.06, due to a lesser amount of asphalt pavement being installed than the estimated quantity in the bid documents. We recommend that the work be approved and accepted, and that final payment be authorized at the expiration of the lien period. 4-12-90 75-0264 r,l "",,'"'_.. .....~.....~........'::I..... ............................ ~.. at Devil's C~nyon Channel File No. 6.218-2 Plan No. 7443 ENGINEERING DIVISION DEPARTMENT OF PUBLIC WORKS CITY OF SAN BERNARDINO, CALIFORNIA CONTRACT CHANGE ORDER NO. !!2- To: Bob Britton, Inc. 171 S.
