SUBJECT:

                     RESOLUTION APPROVING CHANGE ORDER NUMBER 1 FOR BID SCHEDULE NO. 1197, PUBLIC WORKS UNDERGROUND TANK RETROFIT PROJECT 

 

PURPOSE: 

Staff is requesting Council approval for Change Order Number 1 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.  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.  The additional work items were for anticipated work that is typically needed when underground tanks are uncovered. Council approved awarding the base bid and the work item options; however, the work item options were omitted from the resulting resolution number 27,165, which stated only the base bid amount of $739,446.00 (not the base bid plus options total of $908,978.00)

ANALYSIS: 

As the project has progressed, it has been confirmed that $115,883.00 of the previously identified potential additional work items need to be completed (Table 1).  There have also been additional items discovered that require correction, which will cost $28,872.62 (Table 2). Change Order No. 1 in the amount of $144,755.62 ($115,883.0 plus $28,872.62) will increase the total contract price to $884,201.62.  This is a 19.5 percent increase in the original contract amount, but still below the $908,978.00 of the originally contemplated base bid plus options total.  In addition, the change order will extend the date of completion to October 13, 2006, as an additional 41 work days will be required to complete the necessary items.
