application by CONTRACTOR and consideration by ENGINEER is set forth in Specification
Section 01600.
15.BASIS OF DESIGN AND MAJOR EQUIPMENT ITEMS:
Basis of Design: Unless otherwise indicated, design of this Project is based upon the material or
Supplier's equipment named in the list of manufacturers in a Specification section. ENGINEER has
performed an evaluation of other listed manufacturers for compliance with the requirements of the
Contract Documents. When other manufacturers are listed, CONTRACTOR may be required to
make modifications or adjustments, at CONTRACTOR'S expense, to coordinate the installation of
the furnished equipment with associated elements of Work, such as piping and electrical connections,
or support and mounting provisions.
Major Equipment Items:
Bidders shall include in their Lump Sum Contract Price the installed cost of material or
equipment listed as Item A in the Major Equipment Schedule in the Bid Form.
Design of selected items of material or equipment for this Project are based upon Supplier’s
material or equipment named as Item A in the Major Equipment Schedule. Identified as Item B
A2-IB-4
or C is the name of Supplier(s) whose equipment or material is considered by ENGINEER to be
equal in quality, function and performance. Bidders shall write in the installed cost of Items A, B
(if listed), C (if listed), and D (if listed), E (if listed).
A substitute to Item A, B, C , D, or E may be offered by Bidder by writing in the name of a
proposed Supplier as a substitute item. If Bidder offers a substitute, write in the installed cost of
the substitute item also.
The installed cost of each item includes:
a) Cost of a complete operating installation. Include additional costs such as overhead and
profit for changing or modifying the Work such as piping, mechanical, electrical, structural
support, accessories, and controls necessary to accommodate substitute item into the Project.
b) Cost of preparation of drawings and details showing modifications, if any, to
accommodate substitute equipment.
c) Cost for the total number of units called for by the Contract Documents.
Award of the Contract will be made on the basis of the Lump Sum Contract Price based on
Item A as listed on the Major Equipment Schedule, without consideration of Item B, C, D, E, or
substitute item or alternates. The price for each alternate will be the amount added to or deducted
from the base Bid if OWNER selects the alternate. OWNER shall have the right to accept
alternates in any order or combination or to not accept any, unless specifically otherwise
provided.Acceptance of alternates will not be used to determine Successful Bidder.
Not more than 30 days after the Effective Date of the Agreement, OWNER may select Item B, C,
D, E, or substitute item in lieu of Item A, and Bidder agrees, upon notice of selection, to furnish
and install the material or equipment item selected.
If OWNER selects substitute item, the procedures for submission and consideration by
ENGINEER for determining the acceptability of substitutes are set forth in the General
Conditions and in the Specifications. Should the substitute be unacceptable, CONTRACTOR
shall provide Item A for the price bid.
POST-BID SUBMITTALS:

minority business enterprises (MBE’s) and Women’s business enterprises (WBE’s) must be contacted
and documented according to the contract guidance, and submitted to OWNER within 5 days after the
Bid opening date. Although CONTRACTOR’s are required to solicit small businesses in urban and
rural areas (SBRA’s), this solicitation does not count toward the MBE/WBE minimum goal of 8%.
C. In case of inadequate compliance with the above requirements, CONTRACTOR will be subject to
the enforcement provisions of s. NR 162.12 (4), Wis. Adm. Code.
A2-IB-5

employees will be a party to any resulting contract.
The Contractor acknowledges to and for the benefit of the Wisconsin DNR that it understands that
goods and services under this Agreement may be funded with monies made available by the Federal

provisions commonly known as “Buy American” that require all of the iron, steel and manufactured
goods used in the project be produced in the United States (“Buy American Requirements”). The
Contractor hereby represents and warrants to and for the benefit of the WDNR that (a) the Contractor
has reviewed and understands the Buy American Requirements, (b) all of the iron, steel, and
manufactured goods used in the project will be and/or have been produced in the United States in a
manner that complies with the Buy American Requirements, unless a waiver of the requirements is
approved, and (c) the Contractor will provide any further verified information, certification or
assurance of compliance with this paragraph, or information necessary to support a waiver of the Buy
American Requirements, as may be requested by the WDNR. Any failure to comply with this
paragraph by the Contractor shall permit the WDNR to recover as damages against the Contractor
any loss, expense or cost (including without limitation attorney's fees) incurred by the WDNR
resulting from any such failure (including without limitation any impairment or loss of funding,
whether in whole or in part).
