SECTION 07 84 00.00 22 Page 7

Photographs may be provided in electronic (.jpeg or .pdf) format.

Photographs must provide sufficient angles and detail to show conformance with requirements of the system.

The means of inspection must be coordinated with the DFPE prior to the inspection. At this inspection, the manufacturer's technical representative of the firestopping material must be present. The manufacturer's technical representative may be the Firestopping Installer.

For all projects, do not cover or enclose the firestopped areas until inspection is complete and approved by the Contracting Officer. Inspect the applications initially to ensure adequate preparations (clean surfaces suitable for application, etc.) and periodically during the work to assure that the completed work has been accomplished according to the manufacturer's written instructions and the specified requirements. Submit written reports indicating locations of and types of penetrations and types of firestopping used at each location; record type by UL listed printed numbers.

3.3.1 Inspection Standards

3.3.1.1 The Firestopping Inspector must verify that the materials and systems used for firestopping and fire resistive joint systems are listed and labeled for the use intended.

3.3.1.2 The Firestopping Inspector must verify that the required firestop systems and fire resistive joint systems have been installed.

3.3.1.3 The Firestopping Inspector must verify compliance of the firestop systems and fire resistive joint systems by observing the installation process and by taking and recording measurements of the substrates and materials being installed or by destructive examination of completed installations.

3.3.1.4 Inspection frequency of firestop systems and fire resistive joint systems will depend on the method of inspection and the scope of the project.

3.3.1.4.1 The method of inspection for firestop systems must be one of the following:

a. The Firestopping Inspector must be on site during installation and randomly witness a minimum of 10% of each type of firestop system being installed, or

b. The Firestopping Inspector must conduct a post installation inspection, which requires destructive type verification of the firestop system and repair of the firestop system. A minimum of 2%, but not less than one, of each type of firestop system must be inspected per floor or for each area of a floor when a floor is larger than 10,000 SF. An area consists of 10,000 SF or less.

3.3.1.4.2 The method of inspection for fire resistive joint systems must be one of the following:

SECTION 07 84 00.00 22 Page 8

3.3.1.6 Prior to construction, the Firestopping Inspector must coordinate with the NAVFAC DFPE to determine the types of firestop systems and subsequently the number of each type that is to be inspected. The determination of a "type" will typically be a function of a unique combination of parameters, including penetrant type (for example, metal pipe, plastic pipe, cabling), firestop material or device (for example, intumescent caulk, collar, sealant), penetrated substrate (for example, gypsum wall, concrete floor, composite floor deck), and rating of penetrated item.

3.3.1.7 Any type of firestop system that does not comply with this specification will require repair or replacement and re-inspection of that firestop system plus one full additional inspection, of the number specified herein, of that type firestop system. If non-compliance occurs on 10% or more of the quantity of firestop products or firestop systems, then inspection of those particular type firestop systems must cease. The Firestopping Installer must inspect their own work, and repair or replace those like firestops within the area prior to re-commencement of inspections by the Firestopping Inspector.

3.3.1.8 The Firestopping Inspector must maintain inspection forms. All observed deficiencies must be documented and marked on the inspection forms. In addition, the Firestopping Inspector must physically identify the location where a required firestop system has been omitted or where the inspection results indicate that the installed firestop system does not comply with the inspection documents.
