EXECUTION EXAMINATION Examine substrates and conditions, with Installer present, for compliance with requirements for opening configurations, penetrating items, substrates, and other conditions affecting performance of the Work. Proceed with installation only after unsatisfactory conditions have been corrected. PREPARATION Surface Cleaning: Before installing penetration firestopping systems, clean out openings immediately to comply with manufacturer's written instructions and with the following requirements: Remove from surfaces of opening substrates and from penetrating items foreign materials that could interfere with adhesion of penetration firestopping materials. Clean opening substrates and penetrating items to produce clean, sound surfaces capable of developing optimum bond with penetration firestopping materials. Remove loose particles remaining from cleaning operation. Remove laitance and form-release agents from concrete. Retain paragraph below if products selected require priming. Prime substrates where recommended in writing by manufacturer using that manufacturer's recommended products and methods. Confine primers to areas of bond; do not allow spillage and migration onto exposed surfaces. INSTALLATION General: Install penetration firestopping systems to comply with manufacturer's written installation instructions and published drawings for products and applications. Install forming materials and other accessories of types required to support fill materials during their application and in the position needed to produce cross-sectional shapes and depths required to achieve fire ratings. After installing fill materials and allowing them to fully cure, remove combustible forming materials and other accessories not forming permanent components of firestopping. Install fill materials by proven techniques to produce the following results: Fill voids and cavities formed by openings, forming materials, accessories and penetrating items to achieve required fire-resistance ratings. Apply materials so they contact and adhere to substrates formed by openings and penetrating items. For fill materials that will remain exposed after completing the Work, finish to produce smooth, uniform surfaces that are flush with adjoining finishes. IDENTIFICATION Wall Identification: Permanently label walls containing penetration firestopping systems with the words "X HOUR FIRE AND/OR SMOKE BARRIER - PROTECT ALL OPENINGS," using lettering not less than 3 inches (76 mm) high and with minimum 0.375-inch (9.5-mm) strokes. Replace X with 1, 2, or 3 hr fire rating. Locate in accessible concealed floor, floor-ceiling, or attic space at 10 feet (4.57m) from end of wall and at intervals not exceeding 20 feet (9.14m). In mechanical equipment rooms, electrical rooms, tele data rooms and utility shaft areas without ceilings, wall identification shall occur at 15 ft intervals at a height of 10 ft above finished floor level. Retain "Penetration Identification" Paragraph below if required. Individual joint penetration labeling may not be required by authorities having jurisdiction if wall is identified, but labeling is useful if penetration firestopping systems must be replaced. Penetration Identification: Identify each penetration firestopping system with legible metal or plastic labels. Attach labels permanently to surfaces adjacent to and within 4 inches (150 mm) of penetration firestopping system edge so labels are visible to anyone seeking to remove penetrating items or firestopping systems. Use mechanical fasteners or self-adhering-type labels with adhesives capable of permanently bonding labels to surfaces on which labels are placed. Include the following information on labels: The words "Warning - Penetration Firestopping - Do Not Disturb. Notify Building Management of Any Damage." Firestop contractor's name. UL Design No. of firestop assembly. Date of installation. Manufacturer's name. Installer's name. FIELD QUALITY CONTROL If required, inspection of penetration firestopping systems in this article is performed according to ASTME2174, "On-Site Inspection of Installed Fire Stops." To prevent conflicts of interest, ASTME2174 precludes making Contractor responsible for engaging the testing agency. Inspectors may verify compliance by destructive examination of some completed installations. University will engage a qualified testing agency to perform tests and inspections according to ASTME2174. Where deficiencies are found or penetration firestopping systems are damaged or removed because of testing, repair or replace penetration firestopping system to comply with requirements. Proceed with enclosing penetration firestopping systems with other construction only after inspection reports are issued and installations comply with requirements. Contractor shall be responsible for ensuring all penetrations are correctly firestopped prior to requesting the qualified testing agency inspection. Costs for re-inspections and repeat site visits will be at the contractors expense. CLEANING AND PROTECTION Clean off excess fill materials adjacent to openings as the Work progresses by methods and with cleaning materials that are approved in writing by penetration firestopping system manufacturers and that do not damage materials in which openings occur. Provide final protection and maintain conditions during and after installation that ensure that penetration firestopping systems are without damage or deterioration at time of Substantial Completion. If, despite such protection, damage or deterioration occurs, immediately cut out and remove damaged or deteriorated penetration firestopping material and install new materials to produce systems complying with specified requirements.
