4.
Allow room for expansion of the anchoring devices where necessary.
5.

7.
Joint Width: Cut stone to produce uniform joints 3/8 inch (10 mm) or as shown on drawings.
8.
Provide chases, reveals, reglets, openings, and similar features as required to accommodate adjacent work.
9.
Grade and mark stone to achieve uniform appearance when installed. Inspect finished stone units at fabrication plant. Replace defective units.
** NOTE TO SPECIFIER ** The minimum recommended joint width is 3/8 inch for pieces with sawn beds and joints. Larger joint widths are required if pieces have split or otherwise rough cut beds and/or joints.
1.
Pieces shall be bedded and jointed as shown on the approved shop drawings, and bed and joint surfaces shall be cut as follows:
** NOTE TO SPECIFIER ** Select one of the three paragraphs below, delete paragraphs not required. Select the first paragraph for most applications where a 3/8 inch bed or joint width is used. Select the second paragraph for pieces 4 inches or more in thickness when cost savings may be achieved by eliminating the full sawn specification. Select the third paragraph only for projects with bed and joint widths of 3/4 inches or more where a split face or other rough sawn appearance is specified.
a.
Bed and joint surfaces shall be sawn through the full thickness of the granite piece. Bed and joint surfaces shall be within +/- 3 inches (76 mm) of 90 degrees to the face of the piece unless otherwise specified.
b.
Beds and joints shall be sawn or cut full square 2 inches (51 mm) back from the face and from that point may fall under square not more than 1 inch in 12 inches (25 mm in 305 mm). Both beds and joints shall be reasonably free of large depressions.
c.
Beds and joints shall be split or rough sawn generally square with the face and may fall under square with the face not more than 2 inches in 12 inches (51 mm in 305 mm).
** NOTE TO SPECIFIER ** Select one of the options below. Delete option not required.
Because of physical characteristics, most granite cannot be split to a thickness less than one-third the lesser face dimension. Consequently sawn backs (the first specification) should be specified for most veneers, and are frequently specified also for thicker ashlar, because of design considerations.
First paragraph below is recommended for most building granite.
Second paragraph below is recommended for structural bridge piers, 4 inch or more split face pieces, or other installations of thicker pieces where a sawn back is not required.
1.
Backs of all pieces shall be sawn to approximately true planes.
2.
Backs of all pieces may be either rough or natural quarry split to provide surfaces, which vary not more than 1 inch in 12 inches (25 mm in 305 mm) from true plane and not more than 2 inches (51 mm) from their specified thickness.
3.
Fabricate stone to maintain minimum clearance of 1 inch (25 mm) between backs of stone units and surfaces behind stone.
4.
A minimum cavity void of approximately 1 inch (25 mm) shall be maintained behind ashlar or dimensional granite used as a veneer. This cavity should be adequately ventilated and wept to eliminate the accumulation of moisture behind the granite veneer.
D.
Incidental Cutting and Drilling:
1.
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 moisture collection is likely to occur shall be filled with non-expanding grout or high-modulus elastomeric sealant after installation and final alignment.
E.
