 QC representative regarding the specific requirements of QC, prior to the design development (35%)
Submission.
2.11 Fire Protection Services
The A/E shall have on staff or retain the services of a registered Fire Protection Engineer. The engineer must be
directly involved in the design and review of all fire protection systems, life safety features and construction
criteria for the project. At the 35% submission, the registered Fire Protection Engineer shall prepare a report as
outlined in the Basis of Design, Appendix II. Furthermore, the engineer shall review the 100% submission of
plans and specifications and certify in writing that the design is in compliance with all applicable criteria. This
certification letter shall be submitted to Code 408, Fire Protection Engineering Section, at the 100% submission.
2.12 Design Review Comments (DRC)
The Government will review all submissions. Comments will be provided using the DRC Program. The A/E
shall obtain the review comments from the AIC/EIC and shall resolve and incorporate the comments into the
next submission. The A/E shall respond to all comments with detailed responses in the DRC Program, indicating
what action will be taken to resolve each comment. If a comment is not incorporated, the A/E shall provide a
rationale for not incorporating the comment. These responses must be submitted one week before the next
submission or within 3 weeks after the return of the government review, whichever comes first. The A/E
is encouraged to receive and transmit review comments and responses via e-mail however, the EFA CHES
Bulletin Board System is also available.
2.13 Metric Policy
It is NAVFAC's policy to use the metric system of measurement (System International or SI) for construction
contract documents on all MCON, BRAC, and Family Housing projects. Other new construction may be
designed in metric as determined on a case by case basis. Use the guidelines in Appendix IV in conjunction with
the American Institute of Architects (AIA) MASTERMETRIC Guide for International System of Units (SI) in
Construction Documents and the GSA Region 3's publication M2. Many trade associations also publish useful
metric guides for their products.
Most building products (90-95%) have not or will not change in actual size by the conversion to metric. These
products simply are or will be relabeled in metric units and therefore product availability is not a significant
problem. Some of these products that have been relabeled or renamed will require a consensus among industry
members.
Where required, SI metric units should be used from the planning stages through design, construction, and
maintenance. All dimensions on Drawings and in Specifications shall be in Metric. Where permits are required
from state to state or local agencies, acceptability of metric drawings and calculations by the governing authority
should be verified.
Most NAVFAC design criteria and referenced documents are available either in dual units or as separate
inch/pound and metric documents. Where metric dimensioned guides are not available, the designer shall convert
all dimensions for use in the design. Non-availability of metric manuals is no reason not to prepare the designs in
metric.
