B. If erection of the formwork results in insufficient concrete cover over
reinforcement, stop construction and request instructions from the
Architect/Engineer of record.

D. Nails, Tie Wire, Lag Bolts, Through Bolts, Anchorages: Sized as required, of sufficient strength and composition to maintain formwork positioning while placing concrete.

PART 3 EXECUTION

3.01 EXAMINATION

A. Dimensional lines, levels and centers of foundation must be verified before
erecting formwork. Dimensions must agree with drawings.

B. Strength of foundation concrete to be verified before proceeding with erecting formwork.

3.02 ERECTION: FORMWORK

A. Conform Global SmartBlock™ Forms must be installed in accordance with manufacturer's recommendations. Erect SmartBlock™ forms in a running bond. Corners are overlapped “log cabin” style. Protect forms and connectors from damage.

B. Erect formwork, shoring and bracing to achieve design requirements. All work must conform to ACI 301 requirements.

C. Bracing and shoring must ensure stability of formwork and support construction loads.

D. Design, erect, support, brace, and maintain formwork to support axial, lateral, dynamic and static loads and moments that may occur until such forces can be resisted by the concrete structure. Resultant concrete, members and structures must be of correct shape, size, position, elevation and alignment.

E. Plumb and align all joints.

F. Approval of the Architect/Engineer of record must be obtained before framing openings not indicated on drawings.

3.03 EMBEDDED PARTS, OPENINGS AND INSERTS.

A. Locate, set in place and stabilize items to be cast directly into concrete.

B. Openings, where required, must be formed and stabilized.

C. Work with other sections must be coordinated before locating, forming, placing and stabilizing openings, sleeves, slots, pockets, recesses, bolts, anchors, other inserts and components.

D. Positioning of items must conform to the appropriate section. Masonry anchors must conform to spacing and intervals specified in Section 04300.

E. Manufactures instructions for installation of accessories must be followed.
Positioning must not be compromised during placement of the concrete.

3.04 FORM MAINTENANCE

A. Remove foreign matter on exterior and interior of forms before placing into
position.

B. Cavities must be clear of debris prior to concrete placement.

C. Compressed air or water can be used to remove remaining foreign matter. Ensure clean-outs allow water and debris can drain to exterior.

D. In cold weather, remove ice and snow from interior cavity of forms. Do not use de-icing salts or other chemicals. Unless formwork is within heated space, do not use water to clean out forms. Use compressed air or other method approved by the Architect/Engineer of record to remove foreign matter.

E. Wall finishes requiring bonding to the EPS foam can only be applied to a clean surface. Oxidation, from UV exposure, in the form of yellow dust must be removed from the exterior surfaces. Mild detergent and a stiff brush or pressure washers may be used. Rinse thoroughly with water.

3.05 TOLERANCES OF FORMWORK

A. Tolerances of formwork must be maintained in accordance with ACI 301.

3.06 FIELD QUALITY ASSURANCE

A. Before placement of concrete, inspect erected formwork, shoring, and bracing. Ensure formwork conforms to design, stability and cleanliness and that shoring, bracing, supports, fastenings, ties, accessories and other items are secure and maintain their positions.
