Part 3 - Execution
3.01 EXAMINATION
A. Before installation, examine surfaces to which the Work of this Section depends. Notify [Contractor] if substrates do not comply with requirements of this Section.
B. Do not proceed with Work of this Section until unsatisfactory conditions have been corrected.
C. Commencement of Work will imply acceptance of surfaces.
3.02 PREPARATION
A. Clean surfaces to remove grease, oil, frost or other matter that may affect bonding or installation of articulating sidewalk joint with concrete.
3.03 INSTALLATION
A. General
1. Install articulating joint strips where shown on Drawings.
2. Unless otherwise indicated in the Specifications, install Products in accordance with manufacturer’s printed instructions.
3. Install joint strips at 90º to sidewalk without deviation of more than 3º to line of walkway.
4. Ensure joint strips run full depth and width of slab, and flush with finished top surface of concrete. A 1/4" (6.35 mm) clearance space at each end is permitted if desired for edge tooling.
5. Set top elevation of joint strips to act as a screed guide for achieving desired slab thickness.
6. In the event joint strips are located below the finished concrete surface, use edging tool to form arris or sharp edge detail between slabs.
7. Do not allow joint strips to be higher than the surface of the finished sidewalk under any circumstance.
8. Level sub-base using bottom of joint strips so that joint strips sit flat without gaps on underside.
B. Steel installation pins:
1. Secure sidewalk joint strips using galvanized steel pins of size, number and spacing recommended by manufacturer.
2. Drive pins into ground using the factory pre-drilled holes in joint strips to hold strips plumb, level and at 90º plane to finished surface of sidewalk.
3. Ensure top of pins are left visible just slightly above holes on joint strips.
C. Cutting articulating joint strips:
1. Use only hand or power saws in accordance with manufacturer’s written installation instructions. Do not use chain saw, hand-held portable saw or tool with blade used for ripping.
2. Use appropriate full personal protective gear when cutting.
3. Do not cut joint strips less than 4" (100 mm) length using power equipment.
D. Joining (splicing) articulating joint strips:
1. Use 3" x 5/8" dia. wooden dowels in horizontal center holes of strips.
2. Avoid using lengths less than 12" (305 mm) if possible.
3. Drill additional steel installation pin hole if required using 1/4" (6.35 mm) spaded steel cutting bit.
3.04 FIELD QUALITY CONTROL
A. Special Inspection Coordination:
1. Notify [Engineer] upon completion of Work of this Section prior to placement of concrete for field inspection approval.
SPEC NOTE: In Cast-in-Place Section [03 30 00], specify concrete is to be placed without displacing expansion joint strips from their proper position and ensure maximum contact between joint strips and concrete. Use top surface of joint strips as screed guide to achieve desired slab thickness. Finish sidewalk surface according to accepted finishing procedures.
3.05 CLEANING
A. When the Work is Totally Performed, remove surplus products, tools and waste products and debris other than that caused by the Owner or other Contractors.
3.06 WASTE MANAGEMENT AND DISPOSAL
A. Separate waste materials for [reuse] [and] [recycling] at nearest used building materials facility.
