the D-B contractor's responsibility to use current, applicable codes and standards only to the
extent referenced in the RFP or in the proposal submitted by the successful D-B contractor.
Each Design Criteria Professional should review the D-B contractor's design to determine
compliance with the codes and standards referenced in the RFP and the accepted proposal.
f. Existing Corps of Engineers' guide specifications, engineering instructions, technical
manuals, and Architectural and Engineering Instructions (AEI) include most statutory or
mandatory requirements and lessons learned. It is recommended that the RFP technical
specifications advise offerors as to the availability of these criteria and that those items
required by law, regulation, good engineering practice, and other items essential for the
specific project is included in the RFP.
g. Government standards (ETL's, CE guide specifications, EC's, ER's, EI's, etc.) may be
used in preparing the RFP, but should not be included by reference. Mandatory and essential
requirements should be extracted from the applicable standards and included in the RFP
technical specifications, or the standards may be included as an appendix to the RFP.
h. The RFP should specifically and clearly require O&M manuals and O&M training at
the system level (i.e., HVAC system, electrical distribution system, etc.). During the design
phase, the D-B contractor should develop a list of systems for which O&M manuals and
training will be provided. During the construction phase, the D-B contractor shall complete the
systems O&M manuals based upon actual equipment installed and provide O&M training to the
i. Preparers of RFP's should coordinate the RFP, design submittals, and construction
activities with Corps of Engineers' Mandatory Centers of Expertise. ER 1110-1-8158 lists
these Centers of Expertise; HQUSACE mandates their involvement. For example,
coordination with the ESS and UMCS Centers of Expertise is critical to ensure successful
integration and implementation of the associated systems and equipment.
j. Past experience has shown it is desirable to list the construction cost limitation
(combined design and construction cost) in the RFP. This establishes a level of quality and
places all the offerors on a level playing field. It avoids a misunderstanding by the offeror in
cases where they provide a very high cost proposal when a proposal of lesser scope, quality,
and performance was funded and required.
k. The use of additive alternates in Design-Build RFP's is discouraged. If it is suspected
that the funds available for the project will not be sufficient to obtain all the scope in the initial
RFP, options or bid items should be used to determine what can be obtained within the funds
l. When possible, the offerors should establish the contract period (design and
construction). However, in the RFP the Government may feel it necessary to establish a
maximum construction period. When early completion offers significant advantages to the
Government, the RFP should strongly consider a time-emphasized evaluation factor with an
appropriate weight factor assigned.
m. The D-B contractor is required to provide a design or proposal that meets the
requirements of the RFP. If the RFP allows deviations and the Design-Build contractor is
