1/2-inch flush mount undercut anchor 4,260 10,600

2.2 EQUIPMENT

Assemble at the site of the work, sufficient equipment that is dependable, appropriate and adequate to accomplish the work specified. Maintain the equipment in good working condition.

PART 3 EXECUTION

3.1 ANCHORING AND REINFORCING

Install anchors in accordance with the spacing and edge clearances indicated on the drawings. Anchor capacity is also highly dependent on proper installation. Follow all manufacturer and Evaluation Report installation instructions.

3.1.1 Drilling and Installing Undercut Anchors

Drill holes and perform undercut operation for anchors using drilling equipment and bits suitable for the intended purpose, in accordance with Manufacturer's Printed Installation Instructions and Evaluation Report installation instructions. Diameter of holes must be as recommended by the anchor manufacturer. Unless otherwise shown on the drawings, all holes must be drilled perpendicular to the concrete surface. Deviations more than 5 degrees from perpendicular are not acceptable. Unless otherwise specified, do not drill holes in concrete or masonry until concrete, mortar, or grout has achieved full design strength.

Clean holes, prep holes, and install anchors in accordance with anchor manufacturer's recommendations. Protect threads and anchor from damage during anchor installation. Ensure proper embedment in accordance with manufacturers specifications. Ensure placement in accordance with contract documents.

3.1.2 Unused or Repairs to Drilled Holes

Any holes made for anchors that are not used must be filled with non-shrink, non-metallic grout suitable for the orientation and size of hole and have a minimum compressive strength of 4000 psi. Repair must completely fill hole and be flush with existing concrete or masonry.

Place in accordance with manufacturer's recommended instructions. Final anchor positions must not be within 1 inch of repair patches.

3.1.3 Repair Of Mislocated Or Misdrilled Holes

All mis-drilled holes shall be repaired as directed by the Engineer. Repair of mislocated or mis-drilled holes shall be submitted to COR for Government approval.

3.2 EMBEDDED ITEMS

Existing reinforcing bars or other embedded items in the structure may conflict with specified anchor locations. Existing reinforcing and embedded items must not be damaged during installation of post-installed anchors.

The Contractor must use Radar detection systems, X-Ray, or other appropriate means to accurately locate the position of existing reinforcing bars and embedded items at the locations of the anchors in the field. Scanning method must provide enough accuracy and precision to locate the space between rebar. Structural integrity of existing concrete or masonry must not be impaired by investigating method.

The Frame Weldment is used as the template for locating the anchors. This position can be adjustable within +/- 2" any direction to enable the anchors to be placed such that they miss all existing rebar. The Flat Panel should be centered as best as possible over the existing Cooling Grate as shown in the contract drawings. If reinforcement is, or will be, encountered, contact the Contracting Officer immediately.

3.3 TESTS AND INSPECTIONS

3.3.1 Undercut Anchors

For undercut anchors, periodic special inspection are required as a minimum. Inspections must be in accordance with ICC IBC and the Evaluation Report.

Undercut anchors must be inspected during installation, to verify anchor type, anchor dimensions, base material type, base material age, drill bit, hole dimensions, hole cleaning procedures, anchor spacing, edge distances, base material thickness, effective embedment, tightening torque, adherence to the manufacturer's printed installation instructions, and any additional items recommended in the Evaluation Report.

The Special Inspector must perform proof loading on the first two anchors of each type and size, for each installer. Anchor selection will be determined by the Post-Installed Anchor Special Inspector. Perform confined tension proof load testing in accordance with ASTM E488/E488M .

Use incremental loading for tensile test. Maintain proof load for a minimum of 10 seconds. Consider anchors to have failed if displacement exceeds 0.05 inch D/10, where D is the nominal anchor diameter, or if any of the failure modes listed in ASTM E488/E488M occur.

Undercut anchors must not be torque tested.

Proof loads must be the minimum of the value shown in the table below, or 50 percent of the tension capacity of the anchor:

ANCHOR TENSION PROOF LOAD

(lbs)

1/2-inch Undercut Anchors 2000

3.3.2 Action Required from Failed Tests/Inspections

Immediately report failed anchor locations and test results to the Contracting Officer. Anchors that fail to meet proof load or installation requirements must be regarded as malfunctioning. Do not re-use holes unless specifically allowed by manufacturer's published instructions and approved by the Special Inspector.

If any of the tested anchors fail to achieve the specified proof load within the limits of the contract documents, all anchors must then be tested.

Continuously special inspect and proof load any replacement anchors.

Fill unused anchor holes and patch failed anchor locations in accordance with this specification. Prior to performing the repair, the Contractor must submit to the Contracting Officer for approval, the proposed fill and patch materials.

Additional tests, repairs, delays, or modification of work to accommodate failed tests will be at no additional cost to the Government.

3.3.3 Post-Installed Anchor Special Inspections Report

Report the results of all inspections for every day anchor installation takes place. Submit report as an electronic PDF file to the Contracting Officer for review. The report must include the following:

(1) Exact locations of the inspected and tested work;

(2) Inspector's name;

(3) Date of inspection;

(4) Summary of work completed during the inspection period;

(5) Test results;

(6) Statement by the Special Inspector that clearly identifies the tested anchors as being acceptable or rejected.

(7) Statement by the Special Inspector confirming that the materials and installation procedures conform with the approved contract documents and the manufacturer's published installation instructions.

3.4 DUST CONTROL

Control dust resulting from demolition to prevent the spread of dust and avoid creation of a nuisance in the surrounding area. Do not use water when it will result in, or create, hazardous or objectionable conditions such as ice, flooding, or pollution.
