STATEMENT OF WORK

Work Order Number: 20547 Install Sheet Vinyl 1235

1. GENERAL:

a. Sheet vinyl is not government furnished. Contractor shall supply sheet vinyl and deliver it to building 1235 for installation. See attached drawings for locations of new sheet vinyl.

b. All other materials (adhesives, edge strips, floor stone, seam joining materials, etc.) are to be furnished by the Contractor and of a type suitable for the purpose intended.

c. There is existing carpet to be removed. Contractor is responsible for removal and off-base disposal.

f. Hazardous Materials (HM) Approval. Contractor shall submit a Materials Safety Data Sheet (MSDS) for each chemical and/or compound proposed carpet or vinyl installation to the Base Bioenvironmental Office (90 ADOS/SGGB) for review and approval prior to delivery to the base. A HM is defined in Federal Standard DED-STD-313D, Tables I and II. The definition of materials presenting a health or physical hazard is found in OSHA 29 Code of Federal Regulations 1910.1200(c).

g. Hazardous Materials Management. All HM shall be managed, stored and monitored in full compliance with all applicable local, state, federal and Air Force regulations. Contractors who bring hazardous materials onto FEW AFB without authorization are responsible for any punitive or regulatory actions. Contractors are responsible for proper disposal of containers/hazardous material. Flammable liquids shall be stored in an approved fireproof storage cabinet. All chemicals shall be secured and properly stored when not in use.

h. Prohibited Hazardous Materials. Prohibited materials include those that contain Class 1 ozone-depleting substances (including CFCs, halons, carbon tetrachloride, methyl chloroform and methyl bromide) per Air Force Policy and as regulated by Title VI of the Clean Air Act, specifically Sections 601-607. Other prohibited construction materials include lead (i.e. lead-based paint), asbestos, PCBs or other hazardous substances.

k. Material Storage. Contractors shall protect materials during delivery, storage, handling and installation per manufacturer's printed instructions. Materials should be placed on blocking and covered when necessary to protect from water, dust, direct exposure to sunlight and other elements. Materials should be delivered in original containers or packaging with labels intact. Storage locations shall not interfere with work of other trades. Acceptable temperature and humidity conditions must be maintained. Work areas shall be enclosed, watertight, and heated as necessary to protect finish materials during and after installation

2. SHEET VINYL INSTALLATION: as per Manufacturers Specifications.

Substrates must be dry, clean, smooth and free from paint, varnish, wax, oils, solvents and other foreign matter. In renovation or remodel work, remove any existing adhesive residue* so that 100% of the overall area of the original substrate is exposed.

Allow all flooring materials and adhesives to condition to the room temperature for a minimum of 48 hours before starting the installation. The area to receive resilient flooring should be maintained at a minimum of 65°F (18°C) and a maximum of 100°F (38°C) for 48 hours before, during and for 48 hours after completion. NOTE: When using S-240 Epoxy Adhesive, the maximum room temperature should not exceed 85°F (29°C). During the service life of the floor, the temperature should never fall below55°F (13°C). The performance of the flooring material and adhesives can be adversely affected below this minimum temperature. Conduct calcium chloride tests or percent relative humidity tests. Bond tests should also be conducted for compatibility with the substrate. Please refer to Manufacturers Specifications for, Subfloors and Underlayments. Radiant-heated substrates must not exceed a maximum surface temperature of 85°F (29°C). Concrete floors should be tested for alkalinity. The allowable readings for the installation of Armstrong flooring are 5 to 9 on the pH scale.

3. Fitting: Unroll material and lay flat to allow the roll curl to relax before fitting. The lines and Armstrong logo on the back of the flooring represent trademark edges. Material must be adhered within 4 hours of cutting and fitting. Before installing the material, plan the layout so seams fall at least 6″ (15.2 cm) away from subfloor/underlayment joints. Do not install over expansion joints. When installing over an existing resilient floor, plan the layout so the new seams do not coincide with seams or joints of the existing installation. Recommended fitting procedures include freehand knifing, straight scribing or pattern scribing. Abutting Different Gauges of Resilient Flooring: When installing thinner gauge material next to thicker gauge materials, install thicker material first and then butt a 12″ (30.5 cm) wide piece of S-153 Scribing Felt against the thicker material. Adhere the Scribing Felt to the subfloor withS-235 Adhesive. Use the fine notching of the Armstrong S-891 Trowel over nonporous substrates such as existing resilient flooring, and use the regular notching of the Armstrong S-891 Trowel over porous subfloors such as wood and concrete. Use Armstrong S-184 Fast-Setting Cement-Based Patch and Skim Coat or S-194 Patch, Underlayment and Embossing Leveler to feather the edge of the S-153 Scribing Felt to the level of the substrate. Allow the patch to dry completely before installing the flooring. Scribing Felt is not recommended to be used under the entire installation. For any and all other installation requirements see Manufacturer’s Specifications

4. CLEAN-UP: When complete, remove all debris, scraps and foreign matter. Remove any soiled spots or adhesive with appropriate spot remover. Clean sheet vinyl floor to remove all small debris, dust footprints, etc. all sheet vinyl scraps shall be disposed of off base.

5. SPECIAL CONDITIONS: Sheet Vinyl: Armstrong Connection Corlon # 88702 White Cliffs. Cove Base Johnsonite #28 Medium Gray. An approved equal will be considered provided that it matches the above choice in appearance and technical specifications.

1) The Contractor is responsible to verify all quantities and measurements for sheet vinyl and cove base.
