RESOLUTION WAIVING THE CITY'S PURCHASING POLICIES REGARDING
FORMAL BIDDING PROCEDURES AND ALLOW FOR SINGLE-SOURCE
PURCHASING FOR THE ENGINEERING AND MATERIAL FOR THE UNIT 8
BOILER SUPERHEATER OUTLET STEAM TEMPERATURE
FOR THE CITY OF AMES,IOWA
WHEREAS, the Electric Utility has two high-pressure steam generation units within the
City's Power Plant, referred to as Units No. 7 and 8; and,
WHEREAS, on June 12, 2018, the City Council approved a contract with the original
equipment manufacturer(OEM)of the Unit 8 boiler,the Babcock&Wilcox Company,to model and
study the flow characteristics of the boiler; and,
WHEREAS, the purpose of the study was to identify improvements to control the steam
outlet temperature leaving the superheater of the boiler, especially when the unit is operated at less
than rated output; and,
WHEREAS,Babcock&Wilcox Company recommended two physical changes be made to
the boiler to provide the desired outcome: 1) Replace the original lower sidewall headers of the
boiler with new headers of a slightly different design, and 2)Install eight riser tubes connecting the
boiler's upper headers to the steam drum; and,
WHEREAS, the proposed changes to the boiler, along with cladding of boiler tubes in
targeted areas of the boiler with Inconel alloy(already approved by City Council, and underway),
will assist in mitigating the corrosion in the boiler associated with co-firing refuse derived fuel
(RDF); and,
WHEREAS, staff is recommending that the City Council waive the City's purchasing
policies requiring competitive proposals for this work, due to the fact that Babcock & Wilcox is
uniquely qualified as the designer and manufacturer of the boiler,alone in having in their possession
the original design history of the boiler in their archives, and available to perform the engineering
and fabrication work; and,
WHEREAS,installation of the component will be completed by TEi Construction Services,
Inc.,a firm already under contract for the overall Unit 8 boiler tube replacement project and the cost
to install Babcock&Wilcox's boiler modifications is included in TEi Construction Services existing
tube installation contract; and,
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Ames, Iowa,
that the waiver of the City's Purchasing Policies regarding formal bidding procedures and allowing
a single-source purchase is hereby approved.
