Although the sprinkler contractor may not under contract to install the work, three copies of the revisions requested below are required to obtain a sprinkler permit. 1. A single check detector is shown in our records at this address-see attached map. A double-check detector assembly (DCDA) is required for the fire service supply line servicing Mattress Depot. a. Correspondence dated March 8, 2012 that new suppression work would trigger this requirement was sent to the owner at the time listed on Snohomish County parcel records. b. A letter will be required from the owner, if the owner is allowing the tenant to do the work. c. If a single check detector is currently servicing this area of the building, a Public Works permit will be required to replace this with a double check assembly Please contact Benyam Stephanos, Public Works Plan Reviewer, to discuss this requirement, or if you have questions about Public Works plan review for the fire service. Benyam Stephanos can be reached at 425- 257-7289. d. All replacements of a single check detector to a double check detector should be installed by a private contractor, since the city only installs new services upon request. e. If a single check assembly will be replaced with a double check assembly, the revised sprinkler submittal should include three copies of the following, so that the submittal can be reviewed: i. The fire service for the tenant space should be shown from the tenant space to the city main, including the cross connection. ii. A catalog cut indicating the DCDA manufacturer's model in the Backflow Prevention Assemblies Approved for Installation in Washington State', published by the Washington State Department of Health, current edition. iii. A plan and section of the intended location and installation of the DCDA. The DCDA can be located in an interior or an exterior location, to comply with City of Everett Standard Construction Drawings 515 or 523, attached. iv. The model number of the DCDA should be shown on the drawings. f. The riser room should be identified on the plans. g. A post indicator valve (PIV) is required if there is not direct access to the riser room from outside of the building. h. All plan sheets affected by these revisions.
