3.1 INSTALLATION

A. Forms

1. Assemble forms so forms are sufficiently tight to prevent leakage.

2. Properly brace and tie forms.

3. Make proper form adjustments before, during, and after concreting.

4. Use new forms or used forms that have been cleaned of loose concrete and other debris from previous concreting and repaired to proper condition. Provide smooth liner on forms used for concrete to be exposed if necessary, to attain specified finish quality.

5. Use metal cold joint forms when unable to place concrete for footings, foundations, and slabs in continuous pours.

B. Accessories

1. Provide for installation of inserts, templates, fastening devices, and other accessories to be set in concrete prior to placing.

2. Position anchor bolts for hold-down anchors and columns and securely tie in place prior to placing concrete.

C. Expansion Joints: Install at joints between the floor slab and foundation wall where shown on Drawings.

D. Form Removal: Removal of forms can usually be accomplished in twelve (12) to twenty-four

(24) hours. If the temperature is below fifty (50) deg F or if concrete (stairs, beams, etc.)

depends on forms for structural support, leave forms intact for a sufficient period of time for the concrete to reach adequate strength.
