(1) When fire protection shop drawings are
used to finalize engineering concepts:
(a)
The licensee (a licensed professional engineer) shall provide the design
concept adequate for shop drawing preparation by others. The design concept for
sprinkler systems must include as a minimum:
(i) the density and water flow pressure
requirements for the sprinkler system design;
(ii) the classification of commodities to be
protected; and
(iii) confirmation
of adequate water supply.
(b) A properly qualified technician or
licensee shall execute the design concept and prepare shop drawings. Shop
drawings for sprinkler systems must include as a minimum:
(i) layout of risers;
(ii) cross-mains;

(iv) sprinkler heads;
(v) sizing of pipe;
(vi) hanger locations; and

Such review letter may be made available to appropriate jurisdictional
authorities and interested parties.
(3) For the purposes of (1) (b), a "qualified
technician" is a person who has at least one of the following qualifications:
(a) a national institute for certification in
engineering technologies (NICET) level III technician certification;
(b) a NICET level IV technician
certification; or
(c) 20 years
experience in the field of automatic sprinkler layout in Montana, with the end
of the 20-year experience term terminating February 1, 2002.
(4) A licensee shall not be
required to provide design concepts or letter of review for:
(a) projects exempt from building code
requirements for fire protection;
(b) remodeling involving less than 100
sprinklers to an existing fire protection system, provided there is no change
in occupancy classification, storage configuration, or other change in
occupancy use that would require design concept modifications; or
(c) routine maintenance, when accomplished in
accordance with national fire protection association (NFPA) standard #25,
"Inspection, Testing, and Maintenance of Water-Based Fire Protection
