05/15/15 DESIGN NO. _______ SECTION S01560 INSTALLATION SEQUENCE OF FINISH MATERIALS [Note to Specifier (delete) - This section is intended for projects that must comply with the NYC Green Schools Rating System. Omit section for projects where NYC Green Schools Rating System compliance is not required (Typical of CIP projects, UPK Center conversions and fit-outs). Verify for referenced project.] 1.01 SUMMARY A. This Section includes construction scheduling/ sequencing requirements and procedures necessary to optimize Indoor Air Quality (IAQ) levels for the completed Project. 1. B. Scheduling: Contractor’s Project Schedule finish applications shall allow for: a. Dissipation of emissions from finish materials that off-gas deleterious materials during curing. b. Separation of adsorptive finishes from any potential contaminants during material storage and installation. c. Sequencing installation of materials to comply with IAQ requirements of this Section. Temporary Ventilation During Construction: Contractor shall follow procedures specified in this Section and in Division 15 Sections. 1. When Contractor’s “Project Schedule” requires less than optimal sequencing of finish installation, related to IAQ, provide supplemental “fresh air” ventilation of work areas during construction and restrict/control the use of permanent building mechanical systems prior to Authority’s acceptance of building to prevent contamination of systems by construction wastes and other deleterious substances. a. NYCSCA for Comply with additional restrictions on the use of permanent building mechanical systems prior to Authority acceptance as specified in Section, “IAQ Management During Construction.” INSTALLATION SEQUENCE OF FINISH MATERIALS S01560 - 1 05/15/15 C. DESIGN NO. _______ Duct Cleaning: Contractor shall provide duct cleaning as specified in this Section and in Section 15992. 1.02 DEFINITIONS A. Type 1 Finishes: Materials and finishes which have a potential for short-term levels of off gassing from chemicals inherent in their manufacturing processor installation techniques, or which are applied in a form requiring vehicles or carriers for spreading which release a high level of particulate matter in the process of installation and/or curing. Type 1 Finishes include, but are not limited to the following: 1. 2. 3. 4. 5. 6. 7. B. Composite wood products, specifically including particleboard from which millwork, wood paneling, doors or furniture may be fabricated Adhesives, sealants, and glazing compounds, specifically those with petrochemical vehicles or carriers Wood preservatives, finishes, and paint Control and/or expansion joint fillers All hard finishes requiring adhesive installation Gypsum board and associated finish processes Resilient flooring Type 2 Finishes: Absorbent materials and finishes which are woven, fibrous, or porous in nature and tend to adsorb chemicals off-gassed by Type 1 Finishes or may be adversely affected by particulates. Type 2 Finishes include, but are not limited to the following: 1. 2. 3. 4. 5. 6. Carpet and padding Fabric wall covering Insulation exposed to the air stream Acoustic ceiling materials Fabric covered acoustic wall panels Upholstered furnishings C. Materials that can be categorized as both Type 1 and Type 2 Finishes shall be treated as Type 1 Finishes. D. Materials that are categorized as neither Type 1 nor Type 2 are not bound by the requirements of this Section. 1.03 SUBMITTALS A. NYCSCA Supplementary Construction Schedule: Submit a schedule of construction showing compliance with requirements of INSTALLATION SEQUENCE OF FINISH MATERIALS S01560 - 2 05/15/15 DESIGN NO. _______ this Section as a supplement to the schedule required by Division 1 Section “Construction Progress Documentation.” 1. Show sequence of finishes applications and allowances for curing times. Within each air zone, identify finishes, indicating their type classification as defined above. a. An air zone is that part of any floor area served by a single air handling unit. Contractor’s schedule must address controls in each air zone. b. Indicate and schedule types and duration of temporary ventilation proposed. Show schedule for commissioning procedures and all temporary usage of building mechanical systems, identifying types of filtration used and schedule of filter replacement. 1.04 PREPARATION A. Certify in writing to the Authority that interior environmental control has been implemented as specified below and that required conditions are being maintained, and obtain the Authority’s approval prior to installation of interior finishes. B. Coordination: The Contractor is responsible to schedule and coordinate the work of all finish material installers to assure compliance with the requirements of this Specification Section. 1.05 SEQUENCING FINISH INSTALLATION A. Type 1 Finishes to Type 2 Finishes. B. Exemptions: Substrate materials which must be in-place in order to install any Type 1 Finish are exempt from sequencing requirements defined below. Ventilation requirements are not exempt for this condition. C. Type 1 Finishes: Install Type 1 Finishes in a manner compliant with the following: 1. NYCSCA Allow wet-applied Type 1 Finishes to fully cure prior to commencing installation of adsorbent materials, whether Type 1 or Type 2. INSTALLATION SEQUENCE OF FINISH MATERIALS S01560 - 3 05/15/15 D. E. NYCSCA DESIGN NO. _______ 2. Install all Type 1 Finishes prior to commencing installation of Type 2 Finishes. 3. Allow Type 1 materials that are known to off-gas deleterious vapors, whether due to manufacturing processes or installation techniques, to fully cure prior to installation of Type 2 Finishes. Such materials can include, but are not limited to, composite wood, carpet and cushion, resilient flooring, etc. 4. Remove particulate matter from interior space (whether air-borne or on a surface) prior to installation of Type 2 Finishes. 5. Comply with all ventilation requirements required by this Section and identified below. as Type 2 Finishes: Install Type 2 Finishes in a manner compliant with the following: 1. Do not install Type 2 Finishes until installation of Type 1 Finishes is complete and Flushout has been performed. 2. Protect Type 2 Finishes from contamination by chemical off-gassing and/or air-borne particulates during and subsequent to installation. 3. Avoid installation of Type 1 Finishes during Type 2 Finish installation period. (Refer to ventilation requirements if this condition is unavoidable.) 4. Comply with all ventilation requirements required by this Section and identified below. as Ventilation: Provide ventilation of interior space during finish installation as follows, at a minimum: 1. Ventilation shall comply with Section S01550 IAQ Requirements and all other ventilation requirements outlined in the Specifications. 2. Provide ventilation for the entire duration of installation and curing of wet-applied Type 1 Finishes. INSTALLATION SEQUENCE OF FINISH MATERIALS S01560 - 4 05/15/15 F. DESIGN NO. _______ 3. Provide ventilation for the entire duration of all periods in which Type 2 Finishes are present during installation of Type 1 materials. 4. Provide ventilation at any time when it is desired to dissipate chemical off-gassing emissions and/or air-borne particulates out of the interior environment. 5. Provide ventilation during all periods in which chemical off-gassing and/or air-borne particulate matter pose a health risk to any persons present. If Contractor’s Project Schedule requires sequencing of finish installation that does not comply with this Section, provide the following for such period of construction during which sequencing is non-compliant: 1. Provide supplemental ventilation of work areas as described in Section S01550 IAQ Requirements. 2.
