Title
Resolution Approving a Construction contract between the Town of Castle Rock and 53 Corporation, LLC for the Tank 6B Site Restoration [2803 S. Ridge Rd.]
Body
________________________________________________________________________________
Executive Summary
The purpose of this memo is to request Town Council approval of a Resolution (Attachment A) approving a construction contract (Exhibit 1) with 53 Corporation for the site restoration at Tank 6B. This project demolished Tank 6B, which had failed due to concrete deterioration from Alkali Silica Reaction (ASR). Staff recommends approving a construction contract with 53 Corporation in the amount of $34,650, plus a Town-managed contingency of $3,465 (10% contingency) for a total authorization of $38,115. This item is before council given the accumulative cost of construction for the demolition of Tank 6B which has now exceeded the Town Manager’s limit of $250,000. The original construction contract for this project was $122,560, however due to an increase in excavation and stockpiling quantities which was not accounted for in the original scope of work and changes in priorities for the rebuilding of this tank, the overall cost of the project has increased to $273,925.
Staff Recommendation
Staff recommends Town Council’s approval of the contract between the Town of Castle Rock and 53 Corporation, for the Tank 6B backfill in the amount of $34,650 plus a 10% Town-managed contingency of $3,465 for a total authorization of $38,115.
