AGENDA MEMORANDUM

 

 

Meeting Date:           February 14, 2011

 

From:                          Mike Thornton, Purchasing Manager

 

Subject:                      Resolution authorizing execution of an agreement with Booth & Associates, Inc. to provide engineering services related to the transformer rewind at the airport substation.

 

 

Staff Recommendation:

Staff recommends approval of the resolution authorizing execution of an agreement with Booth & Associates, Inc. for engineering services in the amount of $29,850.00

 

Analysis:

The peak load at the airport is 22MW and two transformers serve the load at the airport; both are 30 MVA.  One 30 MVA transformer is able to handle the entire load; however both transformers are needed in case one is lost.  There is no way to transfer the load to another substation because one of the main backup feeders was eliminated as a result of the underground conversion along Highway 441.

 

The original 30 MVA airport transformer, which has been in service since 1982, was not functioning properly and as a result of the regular dissolved gas analysis, staff knows that it has been evolving gas combinations indicative of overheating.  The transformer has not been placed in an overload condition so these gasses can only be a result of an internal problem.  The transformer was examined by the manufacturer soon after its installation and they were not able to determine the nature of the problem, only that an internal problem exists.  This unknown problem increases the possibility that a failure could occur in the original 30 MVA transformer.

 

Since budgetary constraints prevent the purchase of a new transformer, this transformer needs to be completely rebuilt and updated.  It will have several monitoring systems and all new relays installed at the time of the rebuild.  This will allow SCADA to gather valuable information and also be able to control the transformer.  While repairs are being made to this transformer, the other 30 MVA transformer will be able to carry the load.  After the rebuild, either of the transformers can be used in case the other fails.

 

Booth & Associates, Inc. will make all new drawings for the connection points and assist with the commission of the new equipment.  Since they have previously had an existing continuing services contract with the City and they have done extensive work on large projects for the Electric Department, including transformer projects, the Purchasing Division feels that it is in the best interest of the City to utilize their services.

 

The amount of the agreement is below the $35,000 dollar threshold as detailed in Florida Statute 287.055 excluding this acquisition from the requirements of the Consultants Competitive Negotiation Act (CCNA).

 

Options:

1.  Execute the agreement with Booth & Associates, Inc. or;

2.  Such alternative action as the Commission may deem appropriate

 

Fiscal Impact

Funding was included in the fiscal year 2009-10 budget and subject to Commission approval, will be rolled to fiscal year 2010-11.
