PART 3 EXECUTION 3.1 GENERAL

A. Place grout as shown and in accordance with manufacturer’s instructions. B. If manufacturer’s instructions conflict with the Specifications do not proceed until Engineer

provides clarification. C. Dry packing will not be permitted. D. Manufacturers of proprietary products shall make available upon 72 hours notification the

services of a qualified, full time employee to aid in assuring proper use of the product under job conditions.

E. Placing grout shall conform to temperature and weather limitations in Section 03300.

3.2 EQUIPMENT BASEPLATES

A. Concrete base pad

1. Anchor bolts shall be set in plastic sleeves to prevent bonding of grout and to allow for slight error in the base plate hole layout.

2. Anchor bolts shall be accurately set according to foundation drawings and firmly

secured to prevent shifting during concrete placement. 3. Anchor bolt threads shall be protected with heavy grease or wax and wrapping with

plastic sheeting firmly held with wire. 4. Base shall be formed with 2 to 4 inch chamfers on top edges. 5. Chip concrete base approximately ¾ of an inch to remove all laitance and weak or

defective concrete. 6. Coat chipped surfaced with catalyzed epoxy resin.

B. Base plate Installation

1. Install equipment base plates only after concrete has cured for a minimum of 7 days. 2. Remove drivers and driven equipment from base plates 3. Verify “trueness” of base plate 4. Remove any coatings from base plate that are not compatible with the epoxy grout. 5. Position base plate to the proper alignment and elevation with jack bolts. If shims or

wedges are used for leveling they shall be blocked out to allow for their removal after the grout has cured.

6. Install lubricated bolts into any threaded hole in the base plate to prevent grout from entering.

C. Epoxy Grout Forms

1. Shall be coated with wax prior to installation 2. Shall be watertight to prevent leakage of the epoxy grout. 3. Anchor sleeves shall be filled with a non-bonding pliable material to prevent grout

from entering. 4. Anchor bolt threads shall be greased or waxed to prevent epoxy grout from bonding. 5. Install six (6) inch high stand pipes to maintain head pressure and allow purging of

air during grout installation.

D. Epoxy Grout Placement

1. Epoxy grout shall be mixed and placed according to the manufacturers instructions.

2. Grout shall be prepared and ready for installation to permit a continuous operation to completion.

3. Maintain standpipes once base plate is full to continue purging of air. 4. Wipe purged grout from the air vent holes continuously until the grout stops flowing

from the holes.

E. Equipment Installation

1. Remove forms after grout is adequately cured. 2. Check base plate for voids and repair void areas as required. 3. Remove any shims used for leveling and fill voids left by their removal. 4. Remove any jack bolts used for leveling. 5. Install drive and driven equipment once grout has adequately cured. 6. Torque anchor bolts to manufacturers specifications.

3.3 STRUCTURAL BEARING PLATES

A. After shimming columns metal fabrications to proper grade, properly form around the base plates allowing sufficient room around the edges for placing the grout.

B. Adequate depth between the bottom of the base plate and the top of concrete base must be

provided to assure that the void is completely filled with the non-metallic grout. C. Securely tighten anchor bolts once grout has achieved satisfactory strength. D. Only shims shall be used to level base plates. Anchor bolts shall not be used for this

purpose. 3.4 HANDRAILS AND RAILINGS

A. After posts have been properly inserted into the holes or sleeves, fill the annular space between posts and sleeve with the non-shrink, non-metallic grout.

B. Bevel grout at juncture with post so that moisture flows away from post.
