Any piece of granite showing manufacturing flaws upon receipt at the storage yard or building site shall be referred to the Design Professional for determination as to whether it shall be rejected, patched or redressed for use. PART 2 - PRODUCTS 2.01 GRANITE A. Granite Standard: Granite shall comply with ASTM C615, “Standard Specification for Granite Dimension Stone” for material characteristics, physical requirements, and sampling for selection of granite. 2.02 GENERAL: A. All granite shall be of standard architectural grade, free of cracks, seams, or starts, which may impair its structural integrity or function. Color or other visual characteristics indigenous to the particular material and adequately demonstrated in the sampling or mock-up phases will be accepted provided they do not compromise the structural or durability capabilities of the material. Texture and finish shall be within the range of samples approved by the Design Professional. B. Granite: 1. 2. 3. 4. Manufacturer: Precision Countertops Pattern and Color: Copper Night #6211 Nominal Thickness: 3/4” (laminate edges to thickness shown on drawings) Finish: Polished PART 3 - EXECUTION 3.01 EXISTING CONDITIONS A. Verify that surfaces to receive covering are dry, clean, smooth, sound, well-nailed, free from conditions that would damage covering or impair adhesive-bond, and otherwise properly prepared. Prior to starting work, notify contractor of defects requiring correction. Do not start work until conditions are satisfactory. 3.02 FIELD MEASUREMENTS A. Verify prior to installation. If field measurements differ slightly from drawing dimensions, modify work as required for accurate fit. If measurements differ substantially, notify Architect prior to fabrication. 3.03 INSTALLATION, GENERAL A. Follow manufacturer's directions. Make necessary plastic laminate covering joints with tight, flush, nearly invisible, hairline cracks. Weld seams in solid surfacing to present a monolithic PLASTIC LAMINATE 04 41 00-3 finished appearance. 3.04 FABRICATION A. Dimensional Tolerance 1. 2. 3. 4. 5. Panel Thickness = 3/4" to 1 5/8” ±1/8" Panel Thickness Greater than 1 5/8” ±1/4" Panel Face Dimension ±1/16" Face variation from rectangular ±1/16" Heads (Maximum out of Square)/ Calibrated Edges ±1/16" 3.05 BEDS AND JOINTS A. Pieces shall be bedded and jointed (3/8”) as shown on the approved shop drawings, and bed and joint surfaces shall be cut as follows: 1. Bed and joint surfaces shall be sawn through the full thickness of the granite piece. Bed and joint surfaces shall be within ±3° of 90° to the face of the piece unless otherwise specified. 2. Beds and joints shall be sawn or cut full square 2" back from the face and from that point may fall under square not more than 1" in 12". Both beds and joints shall be reasonably free of large depressions. 3.06 FABRICATION GENAERAL REQUIREMENTS A. Mouldings, washes and drips shall be constant in profile throughout their length, in strict conformity with details shown on approved shop drawings. B. Dress joints straight and at 90 degree angle to face. Shape beds to fit supports. C. Anchor Provision: Cut and drill sink provisions and holes in stone for anchors, fasteners, supports, and lifting devices as indicated or needed to set stone in place. D. Allow room for expansion of the anchoring devices where necessary. E. Where liners are required on the back of panels,secure by means of mechanical anchors. Comply with referenced standards. F. Finish exposed faces and edges of stone, except sawed reveals, to comply with requirements indicated for finish and to match final samples and mockups. G. Joint Width: Cut stone to produce uniform joints 3/8 inch or as shown on Drawings. H. Provide chases, reveals, reglets, openings, and similar features as required to accommodate adjacent work. I. Grade and mark stone to achieve uniform appearance when installed. Inspect finished stone units at fabrication plant. Replace defective units. 3.07 INCIDENTAL CUTTING AND DRILLING A. Panels in excess of 100 pounds (45 kg) may include, at installer’s option,lifting clamp dimples, Lewis holes, or other provisions as required to accommodate the lifting device(s) utilized by the installing contractor. Lifting holes in the top beds of panels or other locations where PLASTIC LAMINATE 04 41 00-4 moisture collection is likely to occur shall be filled with non-expanding grout or high-modulus elastomeric sealant after installation and final alignment. 3.08 CLEANING AND PROTECTION A. Cleaning : Granite shall be shop cleaned at the time of final fabrication. After installation and pointing or caulking are completed, the contractor shall carefully clean the granite, removing all dirt, excess mortar, weld splatter, stains, and/or other site incident defacements . Stainless steel wire brushes or wool may be used, but the use of other wire brushes or of acid or other solutions which may cause discoloration is expressly prohibited. Fabricator should be contacted beforecleaners other than detergents are used. 3.09 PROTECTION OF FINISHED WORK A. After the granite work is installed, the granite shall be properly and adequately protected from damage. Boxing or other suitable protection shall be provided wherever required, but no lumber which may stain or deface the granite shall be used. All nails used shall be noncorrosive. All granite work in progress shall be protected at all times during construction by use of a suitable strong, impervious film or fabric securely held in place. 3.10 PRODUCT CLEANING AND REPAIRING A. Including work of other sections, clean, repair and touch-up, or replace when directed, products which have been soiled, discolored, or damaged by work of this section.
