Consent Item: OFFICE OF CITY CLERK uturfl1 rlit.Ca May 18, 2010 TO: HONORABLE MAYOR AND CITY COUNCIL MEMBERS FROM: CITY MANAGER SUBJECT: CHANGE ORDER NO. 1 TO AGREEMENT NO. A10-12 WITH AMPCO CONTRACTING, INC. FOR DEMOLITION OF FOUR BUILDINGS AT THE FOUNDERS RECREATION SITE RECOMMENDATION: 1. Approve an appropriations budget amendment in the amount of$32,000 from the Parks and Landscape Administration Fund to the Demolition of Four Buildings at the Founders Recreation Site project. 2. Approve Change Order No. 1 to Agreement No. A10-12 with Ampco Contracting, Inc. in the amount of$25,175.50. BACKGROUND/ANALYSIS: On March 23, 2010, the City Council awarded a contract to Ampco Contracting, Inc. in the amount of $42,000 for the Demolition of Four Buildings at the Founders Recreation Site. Work included abatement of asbestos material found in the penetration mastic on the roof of all four buildings. The contractor made the appropriate notification to the South Coast Air Quality Management District and commenced with the abatement. On the first day, they removed roofing tiles and found additional suspect mastic used underneath the tile and as a sealant around the adjacent nail holes. Subsequent review by the third-party certified asbestos consultant confirmed that this material also contained asbestos. Staff negotiated a change order for the abatement work in the amount of $29,175.50, less a credit of $4,000 for abatement services included in the basic contract. The net change order is, therefore, $25,175.50. Resolution of this differing field condition delayed the contractor's progress. In the interest of avoiding delay charges, staff directed the contractor to proceed with the additional abatement work and is now asking the City Council to ratify the transaction by approving a change order in the amount of$25,175.50 and extending the contract time by seven (7) working days. r;7 AGENDA DATE: May 25, 2010 Page 2 SUBJECT: CHANGE ORDER NO. 1 TO AGREEMENT NO.
