Title
Consider a resolution authorizing the Mayor to execute a Contract with IPR South Central LLC for the Bowman Road Culvert Rehab Project.
Body
Four existing 54" Corrugated Metal Pipe (CMP) culverts that cross under Bowman Road near the intersection of Nicole Circle have deteriorated to the degree that an existing high pressure gas main may be exposed and become a risk to the Public. This Project originally went out to Bid in June of this year, and the bids came in above the Engineer's estimate for the method we were proposing due to inflated material cost (High-Density Polyethylene slip-line pipe). On September 26, the City Council approved a resolution rejecting the bids for this project. The City has revised the design and have re-bid the Project using an alternate design incorporating a more structurally sound method of repairing the culverts.
The Project includes demolition of existing concrete rip-rap, removal of mitered ends of damaged pipe and extending new pipe to tie into proposed headwalls, removal and replacement of sidewalk, constructing flumes, and revegetation of all disturbed areas. The method of rehabilitation for the deteriorating CMP pipes will consist of a cast concrete lining of the entire culvert which will occur after all work associated with this project is complete.
The Engineer's estimate was $324,000. The low bid was $357,164.50 by IPR South Central LLC.
Cost: $357,164.50
