Chemawa Indian Health Center Modernization Solicitation Amendment 3, Solicitation 16-102-SOL-00001 Questions and Answers 12/01/15

1. Question: We need a spec for the Static dissipating flooring. There is not one on the finish schedule.

Answer: See attached specification 7309 096536 SF – STATIC-CONTROL RESILIENT FLOORING for the Static Resistive flooring.

2. Question: The Ceramic wainscoting, does it go in all the restrooms? Is it every wall?

Answer: For the restrooms, add new Note 6 to A122: All restroom walls to receive ceramic tile wainscot. See Detail 1 A122.

3. Question: It looks like the carpet may be three choices, Will we have a break-out on where each color goes prior to the bid date?

Answer: Yes; refer to the attached drawings: 7309 Chemawa Mod Plans - Flooring Plan 120115.

4. Question: Are the corridors/common areas in each phase considered to be Option 4 as these corridors and common areas could have asbestos in the flooring or adhesive to secure the tiles down?

Answer: No, the corridors and common areas are defined within the Supplemental Design Clarifications, Drawings SK1-A121 and SK1-A123. Option 4 corridors and common areas are NOT defined within any other construction Phase. The Option 4 corridors and common areas may have asbestos in the flooring and/or adhesives.

PART 2 - PRODUCTS

2.1 PERFORMANCE REQUIREMENTS

A. Static-Dissipative Properties: Provide static-control resilient flooring with static-control properties indicated as determined by testing identical products per test method indicated by an independent testing and inspecting agency.

1. Electrical Resistance: Test per ASTM F 150 with 100-V applied voltage, ESD-STM-7.1.

096536 - 2

a. Average greater than 1 megohm and less than or equal to 1000 megohms when test specimens are tested surface to ground.

b. Average greater than 1 megohm and less than or equal to 1000 megohms when installed floor coverings are tested surface to ground.

2. Static Generation: Less than 300 V when tested per AATCC-134 at 20 percent relative humidity with conductive footwear.

3. Static Decay: 5000 to zero V in less than 0.25 seconds when tested per FED-STD-

101C/4046.1.

2.2 STATIC-DISSIPATIVE RESILIENT FLOOR COVERINGS

A. Static-Dissipative, Vinyl Composition Floor Tile: ASTM F 1066 (vinyl composition floor tile, nonasbestos formulated), Class 2 (through-pattern tile).

1. Static Dissipative Tile (SDT™) by Armstrong, or approved

2. Thickness: Not less than 0.125 inch.

3. Size: 12 by 12 inches.

4. Colors and Patterns: As selected by Architect from full range of industry colors.

2.3 INSTALLATION MATERIALS

A. Trowelable Leveling and Patching Compounds: Latex-modified portland cement or blended hydraulic-cement-based formulation provided or approved by manufacturer for applications indicated.

B. Static-Control Adhesive: Provided or approved by manufacturer; type that maintains electrical continuity of floor-covering system to ground connection.

1. Adhesives shall comply with the following limits for VOC content:

a. VCT: Not more than 50 g/L.

C. Grounding Strips: Provided or approved by manufacturer; type and size that maintains electrical continuity of floor-covering system to ground connection.

D. Maintenance Floor Tiles: Special floor tiles inscribed "Conductive floor. Do not wax."

E. Floor Polish: Provide protective, static-control liquid floor polish products as recommended by floor-covering manufacturer.

PART 3 - EXECUTION

3.1 PREPARATION

A. Prepare substrates according to manufacturer's written instructions to ensure adhesion of static-control resilient flooring and electrical continuity of floor-covering systems.

096536 - 3

B. Concrete Substrates: Prepare according to ASTM F 710 and as recommended by manufacturer.

Do not use solvents for cleaning substrates.

C. Do not install static-control resilient flooring until it is same temperature as space where it is to be installed.

1. Move static-control resilient flooring and installation materials into spaces where they will be installed at least 48 hours in advance of installation.

D. Sweep and vacuum substrates to be covered by static-control resilient flooring immediately before installation.

3.2 INSTALLATION, GENERAL

A. Install static-control resilient flooring according to manufacturer's written instructions.

B. Embed grounding strips in static-control adhesive. Extend grounding strips beyond perimeter of static-control resilient floor-covering surfaces to ground connections.

C. Scribe, cut, and fit static-control resilient flooring to butt neatly and tightly to vertical surfaces and permanent fixtures including built-in furniture, cabinets, pipes, outlets, and door frames.

D. Extend static-control resilient flooring into toe spaces, door reveals, closets, and similar openings. Extend static-control resilient flooring to center of door openings.

E. Maintain reference markers, holes, and openings that are in place or marked for future cutting by repeating on static-control resilient flooring as marked on substrates. Use chalk or other nonpermanent, nonstaining marking device.

F. Adhere static-control resilient flooring to substrates using a full spread of static-control adhesive applied to substrate to produce a completed installation without open cracks, voids, raising and puckering at joints, telegraphing of adhesive spreader marks, and other surface imperfections.

G. Integral-Flash-Cove Base: Cove static-control flooring 6 inches up vertical surfaces. Support static-control resilient flooring at horizontal and vertical junction with cove strip. Butt at top against cap strip.

1. Install metal corners at inside and outside corners.

3.3 FLOOR-TILE INSTALLATION

A. Comply with manufacturer's written instructions for installing floor tile.

B. Lay out floor tiles from center marks established with principal walls, discounting minor offsets, so floor tiles at opposite edges of room are of equal width. Adjust as necessary to avoid using cut widths that equal less than one-half floor tile at perimeter.

1. Lay floor tiles square with room axis.

096536 - 4

C. Match floor tiles for color and pattern by selecting floor tiles from cartons in same sequence as manufactured and packaged if so numbered. Discard broken, cracked, chipped, or deformed floor tiles.

1. Lay static-dissipative, vinyl composition floor tiles with grain direction alternating in adjacent floor tiles (basket-weave pattern).

D. In each space where conductive, solid vinyl floor tile is installed, install maintenance floor tile identifying conductive floor tile in locations approved by Architect.

3.4 CLEANING AND PROTECTION

A. Comply with manufacturer's written instructions for cleaning and protection of static-control resilient flooring.

B. Protect static-control resilient flooring from mars, marks, indentations, and other damage from construction operations and placement of equipment and fixtures during remainder of construction period.

C. Cover static-control resilient flooring until Substantial Completion.
