Gateway Park Center PERKINS+WILL <br /> 810495.000 <br /> 12/06/18 <br /> <br /> <br />TEMPORARY FACILITIES AND CONTROLS <br />01 50 00 - 9 <br /> <br /> <br />1. Indicate procedures for discarding water-damaged materials, protocols for <br />mitigating water intrusion into completed Work, and replacing water-damaged <br />Work. <br />2. Indicate sequencing of work that requires water, such as sprayed fire- <br />resistive materials, plastering, and terrazzo grinding, and describe plans for <br />dealing with water from these operations. Show procedures for verifying that <br />wet construction has dried sufficiently to permit installation of finish <br />materials. <br />3. Indicate methods to be used to avoid trapping water in finished work. <br />B. Exposed Construction Period: Before installation of weather barriers, when <br />materials are subject to wetting and exposure and to airborne mold spores, protect <br />as follows: <br />1. Protect porous materials from water damage. <br />2. Protect stored and installed material from flowing or standing water. <br />3. Keep porous and organic materials from coming into prolonged contact with <br />concrete. <br />4. Remove standing water from decks. <br />5. Keep deck openings covered or dammed. <br />C. Partially Enclosed Construction Period: After installation of weather barriers but <br />before full enclosure and conditioning of building, when installed materials are still <br />subject to infiltration of moisture and ambient mold spores, protect as follows: <br />1. Do not load or install drywall or other porous materials or components, or <br />items with high organic content, into partially enclosed building. <br />2. Keep interior spaces reasonably clean and protected from water damage. <br />3. Periodically collect and remove waste containing cellulose or other organic <br />matter. <br />4. Discard or replace water-damaged material. <br />5. Do not install material that is wet. <br />6. Discard and replace stored or installed material that begins to grow mold. <br />7. Perform work in a sequence that allows wet materials adequate time to dry <br />before enclosing the material in gypsum board or other interior finishes. <br />D. Controlled Construction Period: After completing and sealing of the building <br />enclosure but prior to the full operation of permanent HVAC systems, maintain as <br />follows: <br />1. Control moisture and humidity inside building by maintaining effective dry -in <br />conditions. <br />2. Use temporary or permanent HVAC system to control humidity within ranges <br />specified for installed and stored materials. <br />3. Comply with manufacturer's written instructions for temperature, relative <br />humidity, and exposure to water limits. <br />3.7 OPERATION, TERMINATION, AND REMOVAL <br />A. Supervision: Enforce strict discipline in use of temporary facilities. To minimize <br />waste and abuse, limit availability of temporary facilities to essential and intended <br />uses.
