W.O. 16-07, Interstate 90 Water Main Crossing Project, will install approximately 3,000 lineal feet of 24-inch diameter trunk water main from the intersection of Gabel Road and South 24th Street West to the intersection of Elysian Road and East Lane.  Work includes installing over 800 linear feet of pipe under Hogan Slough, MRL railroad tracks, Interstate 90 and the South Frontage Road using trenchless methods.  Bid options for the trenchless portion of the work include using either the jack and bore or the directional drilling method.  Alternates for different casing and carrier pipe materials are also bid options.

After being advertised in the Billings Times and on the City website March 10, 17 and 24, staff opened bids on March 29.  Staff recommended that City Council delay awarding a contract until the April 25 meeting date in order to give staff additional time to review the bids.  After evaluating the bids further, staff recommends that City Council award the construction project to 
Kinkaid Civil Construction in the amount of $1,233,366.00.

City Council may:

• Approve award of the construction contract to Kinkaid Civil Construction, or;
• Disapprove award of the construction contract to Kinkaid Civil Construction.  If the project is not constructed, the City's 2015 water main extension on Elysian Road will experience long-term problems maintaining water quality due to the large volume of water not being circulated through the the mile-long 24-inch diameter dead end pipe.

After evaluating several factors, staff recommends that the 800-foot crossing of MRL railroad tracks, I-90 and the Frontage Road be constructed by the horizontal directional drilling method using 30-inch fusible PVC casing and 24-inch fusible PVC carrier pipe.  Staff also recommends that 1,400 feet of PVC water main be used in the open-cut portion of the work in lieu of ductile iron water main.  Finally, staff recommends that additives for a 2-inch mill and overlay of East Lane and traffic control for potential intermediate bore pits be awarded in case they are needed for the project.  As a result, staff recommends that the City Council award a construction contract to Kinkaid Civil Construction in the amount of $1,233,366.00.

The project was budgeted in FY16 and utilizes water funds.
