The City currently disposes of its solid waste at the City of Billings Regional Landfill. The Phase 2 cell is filled to capacity, so a soil cover system must be constructed over the filled cell to comply with state and federal regulations.  The cover is comprised of a 4-foot thick layer of native soil and a 0.5-foot thick layer of native topsoil.  The project also includes installation of a geosynthetic clay liner under the south access road, road gravel surfacing, drainage improvements, seeding, and erosion control.  Alternate 1 involves constructing and installing a lysimeter that MDEQ may require.  If MDEQ deems the lysimeter unnecessary, it will be removed from the contract and the respective amount credited via change order.  The project was designed by Great West Engineering, with whom the City has a contract for these professional services.

Bids were opened for the Phase 2 closure on February 15, 2011, and by law, Council must act on the bid opening at this meeting.  There were eleven bidders and COP Construction was the low bidder.

Council may:

• Award the base bid with the alternate as recommended by Staff; or 
• Reject all bids and not award a contract.  The staff would rebid the project at a later time or as directed by Council. 

This project is being funded by the Landfill Infrastructure Fund. The FY 2011 budget includes funds to cover the construction costs of the Phase 2 closure.

Approved Funding Amount in 2010 and 2011 CIP: $ 623,000.00
Amount being requested for Phase 2 closure:                $  (576,320.00)
Remaining Funding:                                                 $   46,680.00
