SUBJECT: RESOLUTION APPROVING CHANGE ORDER NUMBER 2 FOR BID SCHEDULE NO. 1197, PUBLIC WORKS UNDERGROUND TANK RETROFIT PROJECT

 

PURPOSE:

 

Staff is requesting Council approval for Change Order Number 2 for Bid Schedule No. 1197, Public Works Underground Tank Retrofit Project.

 

BACKGROUND:

 

On February 7, 2006, Council approved contract documents and awarded the construction contract to West Star Environmental, Inc. for Bid Schedule No. 1197, Public Works Underground Tank Retrofit Project for $739,446. Staff�s report to Council included a recommendation to award the contract not only for the base bid amount, but also for additional work item options totaling $169,532.00. Council approved awarding the base bid and the work item options; however, the work item options were omitted from the resulting Resolution No. 27,165, which stated only the base bid amount of $739,446.00 (not the base bid plus options total of $908,978.00). On August 29, 2006, Council approved Change Order No. 1, adding $144,755.62 and 41 work days to the contract for previously identified potential additional work items and for additional items discovered that required correction. Change Order No. 1 increased the contract amount to $884,201.62.  

 

ANALYSIS:

 

As the project has progressed on the remaining fuel tank sites, deficiencies in the existing underground piping and other fuel related systems has been identified.  To correct these deficiencies, it is necessary to add further work items (Table 1) to the contract. Change Order No. 2 in the amount of $134,007.88 will increase the total contract price to $1,018,209.50. In addition, the change order will extend the date of completion to January 19, 2007, as an additional 65 work days will be required to complete the necessary items.
