Discussion:
On March 7, 2017, City Council adopted Resolution 7845 which approved the plans and specifications and authorized staff to advertise for bids for the Whispering Oaks Sanitary Sewer Extension, Project 2017-3.
On April 25, 2017, a bid opening was held on the project, in which there were six bids opened. The bid proposals had a bid Part A (sanitary sewer only) and a bid Part B (sanitary sewer and watermain). The bids are summarized in the attached resolution.
For the bid opening, the low bidder for Part A and Part B bid packages is Northwest Asphalt, Inc. with bids of $644,013.90 and $785,984.90, respectively. Shakopee Public Utilities would install the watermain if the cost is less than $70,000. The cost is approximately $85,000, thus SPU does not want to move forward. Resolution 7878 is recommending Bid Package A for sanitary sewer only.
The engineers estimate was $700,000.00 (A) and $900,000.00 (B), respectively.
If Council awards the contract, staff is requesting a contingency amount of 5% of the content to cover minor change orders and quantity adjustments that may occur on the project. Also an extension agreement with Bolton & Menk, Inc. is needed for construction engineering services such as surveying.
