Name and address of the contractor, to include the contractorÕs license number.
Method of protection for nonmetallic piping.
Design density and area.
Water flow information for design purposes may be obtained by contacting the Fire Prevention Division water supply officer at (408) 378-4010.
A maximum of three (3) complete sets of shop drawings (two will be stamped and returned), drawn to 1/8" : 1' or 1/4" : 1' scale, with a maximum size of 30"x44" utilizing national recognized symbols as outlined in NFPA Standard 170. Additional stamped sets must be arranged in advance with the Plan Reviewer. For tenant improvement relocation of 15 heads or less, where no new branch or supply piping is installed, a site plan reflecting the location of the work is acceptable.
A completed Permit Application form.
Payment of all fees.
A copy of the current Business License for the city the work occurs in.
Proof of Workers Compensation Insurance
The Santa Clara County Fire Department requires the following inspections and tests on system installations, modifications and alterations. A copy of the approved plans and the permit must be on the job site at all times. The permit number will be required to schedule any inspections:
Shall be conducted prior to covering underground pipe.
Underground piping shall be thoroughly flushed to the satisfaction of the inspector upon completion of the hydrostatic test (see below) and prior to connection to the overhead piping .
Prior to installation, all pipe welds shall be inspected.
Shall be conducted prior to ceiling installation.
Prior to covering or concealing pipe, all new overhead and underground piping, within the scope of work, shall be tested @ 200 psi for a period of two (2) hours. Tenant modifications consisting of new drops or armovers, encompassing an area equal to 25% or greater of the total system coverage, will require a leak test of the complete system @ 50 psi above static pressure. New supply piping for tenant modification work shall be tested @ 200 psi for 2 hours.
The above required inspections must be completed prior to scheduling the final inspection.
Note that the scope of the installation permit provides for one (1) initial and one (1) reinspection for each of the above required inspections. Additional inspections are subject to additional fees. Appointments for inspection are to be scheduled a minimum of twenty-four (24) hours in advance. To schedule an inspection appointment, contact the Fire Prevention Division Secretary at (408) 378-4010 between the hours of 8:00 a.m. and 4:30 p.m. Monday through Friday.
