Design drawings shall be prepared by the contractor and shall demonstrate the configuration of major system components including sprinkler piping and sprinkler locations. Drawings shall indicate the location of existing sprinkler system equipment and where the existing system is to be connected with new sprinkler system equipment. The sprinkler contractor shall field verify locations of all sprinklers and system piping shown on the automatic sprinkler system record drawings provided separately as part of the project information (As -Built drawings dated February 9, 1994, prepared by Smith Fire Systems, Inc). 2. The contractor shall prepare and submit shop drawings to the owner for approval prior to the start of any work. If any changes are made to the location of sprinkler from those shown on the owner -approved shop drawings, those changes shall be approved by the owner and identified in writing to the Everett Fire Department and submitted for approval by the local Authority Having Jurisdiction. All changes shall be approved in writing prior to installation. Any relocations or additional sprinklers required for compliance as a result of the changes shall be furnished and installed at the expense of the contractor. 3. The contractor shall be responsible for verifying and installing a code compliant system regardless of whether owner approval and/or Authority Having Jurisdiction approval is granted. 4. Refer to the Jensen Hughes hydraulic calculation memo and associated hydraulic calculations for water supply information and conceptual design criteria based on the anticipated hazardous classification and use. 5. Accuracy of wall locations and dimensions shall be field verified by the contractor with regards to pipe routing and proximity to obstructions. 6. The scope of work includes the modification of the existing sprinkler system to accommodate architectural, temporary occupancy, and hazard classification changes due to the Connect UP project. The sprinkler contractor shall be responsible for coordinating with new elements being added to the building as part of the overall project such as new light fixtures, fixed elements, suspended ceilings, etc. 7. All sprinkler piping shall be secured using UL listed and FM approved (UL/FM) pipe hangers, anchors, seismic bracing, and other approved means to properly secure the pipe. 8. All piping 1-inch through 2-inch shall be UL/FM ASTM A53, A135, or A795 or A795 schedule 40 with threaded ends. 9. All wet -system piping 2%-inch and larger shall be UL/FM ASTM A53, A135, or A795 schedule 10 with rolled - grooved ends. 10. The work includes all sprinklers, listed schedule 10 and 40 piping, hangers, seismic bracing, and other associated components throughout the building related to the modification of the existing fire sprinkler system. 11. Where flexible sprinkler drops are used, the friction loss for the flexible sprinkler drop shall be provided by and verified by the Contractor. 12. Sprinklers shall be installed in the symmetrical two foot by two foot center of ceiling tiles where applicable. 13. All additional materials, fittings, and other associated equipment required to provide a complete operational system shall be shown on the contractor shop drawings. These fittings shall be incorporated into the finalized hydraulic calculations. A 10 psi pressure cushion will be assumed in all hydraulic calculations, applied to the static and residual pressure information provided by the City of Everett Public Works Department. 14. The work includes connection of water flow and valve supervisory switches to the fire alarm system. The contractor shall be responsible to coordinate these wiring connections with a licensed fire alarm technician and/or electrician. 15. The work includes coordination of all obstructions to new sprinkler piping. Obstructions include but are not limited to emergency lighting, battery boxes, telecom equipment, and wiring. Sprinkler contractor is to coordinate with the Architect and Owner, and the Connect UP architectural drawings prior to finalizing shop - level sprinkler drawings. 16. The work includes related modifications of drain piping, inspector's test connections, drain valves, and piping as necessary to complete the modification work. The drains shall be piped directly to the outside of the building to an approved location by the Architect. 17.
