BACKGROUND Jim Haggerton, Mayor Duane Cameron Bulldozing was awarded the construction contract for side sewer installation at 13906 51 Avenue South for $11,582.31, plus sales tax. Council approval was not necessary for the original contract as it was under the $25,000.00 approval threshold. The Notice to Proceed was issued March 31, 2009. The additional work in Change Order No. 1 is the result of extra labor, equipment and materials required to install side sewer to the house at 13906 51 Avenue South. The as- built plans show a side sewer stub out to the house. However, after many hours of video inspection and excavation, a sewer stub was not found. A new stub had to be installed and the sewer main was found to be 18 feet deep. This is an extraordinary depth that was not expected. This change order will add $28,317.28 to the original contract for a new total contract amount of $39,899.59 (plus tax). Remaining budget is available for this change order from the $75,000 Sewer Infiltration Inflow (I &I) Project (page 122, 2009 CIP). RECOMMENDATION The Council is being asked to approve Change Order No. 1 for the Side Sewer Installation at 13906 51 Ave S Project with Duane Cameron Bulldozing in the amount of $28,317.28 for consideration at the June 22, 2009 Committee of the Whole meeting and subsequent July 6, 2009 Regular Meeting. attachment: Change Order No. 1 W: \PW Eng \PROJECTS\A- SW Projects \09sw02 13906 51 Ave S SSS \Info Memo Change Order 1.doc CITY OF TUKWILA CONTRACT CHANGE ORDER NO. 1 DATE: 05/20/09 BUDGET NO. 402.02.594.353.63.05 PROJECT NO. 09 -SW02 CONTRACT NO. 09 -057 PROJECT NAME: Side Sewer Installation at 13906 51st Avenue South TO: You are hereby directed to make the herein described changes to the plans and specifications or do the following described work not included in the plans and specifications on this contract: NOTE: This change order is not effective until approved by the Owner" and a notice to proceed is issued.
