B. Building occupancy is educational/museum as defined by NFPA 13 (2022) section A.4.3.

C. Unless otherwise indicated, provide a hydraulic calculated wet pipe system for light hazard occupancy. Hydraulic remote areas are permitted to be reduced within the parameters indicated in NFPA 13 (2022) section 19.3.3.2.3 if quick-response sprinklers are utilized.

D. Fire suppression system as-built drawings from March 2008 are available for use in hydraulic design calculations.

E. Existing fire suppression system is fed from a nominal 2,500 gallon pressure tank in accordance with NFPA 22 chapter 7. See notes indicated on Drawings and fire suppression system as-built drawings for capacity and demand utilized for original system design.

F. System residual pressure requirements at design flow rate shall not exceed 90 percent of residual pressure available at design flow rate.

G. Locate sprinkler accessories where indicated on drawings.

H. Seismic protection shall be in accordance with NFPA 13 Chapter 18. Horizontal seismic force shall be calculated as FPW = CP x WP, where CP = 0.754 x SDS per NFPA 13 section

18.5.9.3. The SDS for this structure is 1.11, resulting in a CP of 0.8369 for use in seismic protection design.

I. Fire suppression Drawings are conceptual, representing system design intentions. When Drawings conflict with referenced standards provide protection and an installation complying with referenced standards. Coordinate the installation of the fire suppression system with the work of other building trades and site conditions.

J. Floor plans and building sections are shown to relay relative space layout, floor to floor heights, and ceiling heights and type only. Field verify existing conditions and provide a sprinkler system design and installation to match.

K. Field locate existing mechanical and electrical equipment and coordinate new fire suppression piping installation with existing ducts, pipes, conduits, equipment, structural elements, etc. When portions of existing mechanical, electrical, and structural systems are shown it is not meant to indicate that all of such systems are shown. Field verify portions shown.
