[DaVinci Stone Warehouse Addition]
***Plan Mod for backflow change to Ames C200 Approved 1/8/2019 MAS***The fire sprinkler scope of work consists of building a new warehouse on the back of an existing store and fabrication shop. The existing building was not sprinklered. Install a wet pipe fire sprinkler system throughout the new warehouse as well as the existing store and fabrication shop. The entire building will be protected per NFPA 13, 2016.

[BLD17-04590]
The fire sprinkler system is used for building area increase, for fire area, and for fire flow. To construct a 7,161 square foot warehouse addition on the North end of an existing 10,010 square foot building. After the addition, this building will have a total floor area of about 17,171 square feet (18,078 square feet including the existing 907 square foot mezzanine). For the addition, work is to include concrete footings, concrete stem walls, concrete slab on grade, steel moment frames (beams and columns), steel columns, lateral bracing cables, steel roof purlins, steel roof panels, steel wall purlins, steel wall panels, an overhead door, and side-hinged swinging doors. A liner system with R-38 insulation, a vapor retarder installed on the warm in winter side of the insulation, and thermal spacers will be used to insulate the roof. The walls will be insulated with R-25 insulation with thermal break tape at the horizontal purlins and will have a vapor retarder installed on the warm in winter side of the insulation. Work to be done to the adjacent existing roof to support the added snow drift load includes additional steel purlins, purlin blocking, reinforcing steel plates welded to the top and/or bottom flange of existing steel beams, and additional bolts at existing beam splices. Special Inspection is required for concrete, steel (including bolting and welding), and anchors post-installed in hardened concrete. A new 8-foot-tall masonry trash enclosure will be constructed. A separate permit is required for racks over 8 feet tall. The work is required to comply with the approved drawings, with the structural design, with the plan review report, and with all applicable codes and ordinances. A fire sprinkler system will be installed throughout this building (existing and new addition) in conjunction with this permit. This permit is intended to establish a Certificate of Occupancy for the entire building, the existing building and the building addition. The fire sprinkler system is required to comply with NFPA 13 and the fire alarm system is required to comply with NFPA 72 as regulated by the Fire Department. Separate fire sprinkler permits and fire alarm permits shall be obtained prior to beginning any modification or installation work on such systems. **CJW**
