AGENDA MEMORANDUM

 

 

MEETING DATE:   December 14, 2009

 

FROM:                       Mike Thornton, Purchasing Manager

 

SUBJECT:                  Resolution authorizing the execution of an agreement with Marlon Dunn Contracting, Inc. for conversion of an Effluent Transmission Main

 

 

Staff Recommendation:

Staff recommends approval of the resolution authorizing execution of an agreement with Marlon Dunn Contracting, Inc. to provide construction services for a total amount of $383,232.20.

 

Analysis:

The purpose of this project is to convert an existing effluent (waste water) main to a pressurized reuse water (irrigation) main.  A non-pressurized 20-inch effluent main running from the Canal Street WTF to the Turnpike WTF was installed in the 1980’s.  This main operates at a very low pressure.  In order for this main to be used for reuse water the pressure must be increased.

 

The pressurization and control of the pressure will be accomplished with the installation of additional equipment to include a new pressure-sustaining-valve, flow meter station, associated piping, valves, fittings, pre-cast concrete vaults, and hatches.

 

There are two critical areas that must be reinforced to protect against leaks and line breaks.  The main crosses under US Highway 441 at Canal Street and US S.R. 27 at Vine Street, a High Density Poly Ethylene liner will be installed in the existing ductile iron pipe in these sensitive areas to avoid any possibility of washouts under these major roadways should the joints of the existing line fail.  This process essentially involves inserting a plastic folded liner into the ductile iron pipe.  The liner is unfolded and expanded with heat.  The area between the liner and the pipe is sealed to prevent leaks between the pipe and liner.  This specific method of reinforcing these areas was clearly defined in the technical bid specifications.

 

The completion of this project will provide reuse water to existing customers between Canal and Vine Streets.  Reuse water passing through the pressure sustaining valve located at Vine Street will continue to flow to the Turnpike WTF spray field.

 

Procurement Information:

On September 21, 2009, the Purchasing Division issued Invitation to Bid number 90451.  Notification of this opportunity by legal advertisement in the Daily Commercial was made.  As well as posting on-line at BidSYNC.com.

 

On October 20, 2009, sealed bids were received from three prospective contractors.  Bids were evaluated by both the purchasing staff and the engineer of record on the project, AECOM, USA.  Project references provided by the two lowest bidders were verified by the engineer. 

 

The engineer’s research of the bid information and references revealed the initial low bidder, Prime Construction, sought to provide an alternative method of lining the ductile iron pipe.  The alternative method was unacceptable to the City.  Following the determination Prime Construction’s bid was unacceptable the firm was eliminated from further consideration resulting in Marlon Dunn becoming the lowest priced offeror.

 

The engineer has recommended award to Marlon Dunn Contracting, Inc. as the lowest responsive and responsible bidder.  City staff concurs with the recommendation of the engineer.
