B. Waterstops: Fabricate pieces of premolded waterstop with a maximum practicable length to hold the number of end joints to a minimum. Fabricate joints in waterstops in accordance with the manufacturer's recommendations.

PART 3 - EXECUTION

3.1 CONSTRUCTION OF TEMPORARY FORMWORK

A. In accordance with ACI 301, construct formwork:

1. Design, erect, shore, brace, and maintain formwork to support vertical, lateral, static, and dynamic loads, and construction loads that might be applied, until the concrete structure can support such loads.

2. Obtain approval before framing openings in structural members not indicated on the drawings.

B. Fabricate forms for easy removal without hammering or prying against concrete surfaces.

THRO #328089 6 03 10 00 – 1

1. Provide crush or wrecking plates where stripping may damage cast concrete surfaces.

2. Provide top forms for inclined surfaces where slope is too steep to place concrete with bottom forms only.

3. Chamfer wood inserts for forming keyways, reglets, recesses, and the like to allow wood to swell without spalling concrete and to ensure easy removal.

C. Falsework:

1. Provide positive means of adjustment (wedges or jacks) of shores and struts. Do not adjust formwork after concrete has taken its initial set. Brace formwork securely against lateral deflection and lateral instability.

2. To maintain specified tolerances, camber formwork to compensate for anticipated deflections in formwork prior to hardening of concrete.

Formwork camber calculations are the responsibility of the formwork designer. Set formwork and intermediate screed strips for slabs accurately to produce designated elevations and contours of the finished surface prior to removal of formwork. Ensure edge forms and screed strips are sufficiently strong to support vibrating screeds or roller pipe screeds when the finish specified requires the use of such equipment.

3. When formwork is cambered, set screeds to a like camber to maintain required concrete thickness.

4. Verify lines, levels, and centers before proceeding with formwork. Ensure dimensions agree with the drawings.

5. Fasten form wedges in place after final adjustment of forms and prior to concrete placement.

6. Anchor formwork to shores, supporting surfaces, or members to prevent upward or lateral movement of the formwork system during concrete placement.

7. Securely brace and shore forms to prevent displacement and to safely support construction loads.

8. Construct forms plumb and straight to conform to slopes, lines, and dimensions shown.

9. Set edge forms, bulkheads, and intermediate screed strips for slabs to achieve required elevations and slopes in finished concrete surfaces.

Provide and secure units to support screed strips; use strike-off templates or compacting-type screeds.

10. Provide runways for moving equipment and support runways directly on formwork or structural member without resting on the reinforcing steel.

THRO #328089 7 03 10 00 – 1

D. Where end-of-work sequence requires a joint in the concrete, provide adequately designed additional formwork. Extend reinforcement through formwork and key joints as indicated on the drawings. Location of the construction joint is subject to approval by the Architect and the Structural Engineer.

E. Forms for Exposed Concrete:

1. At construction joints, lap contact surface of the form sheathing for flush surfaces exposed to view over the hardened concrete in the previous placement by not more than 1 inch. Ensure formwork is held firmly against hardened concrete to prevent offsets or loss of mortar at construction joints and to maintain a true surface.

2. Provide watertight formwork when architectural exposed concrete is specified.

3. Unless specified in the Contract Documents, construct formwork so concrete surfaces conform to tolerance limits. The class of surface for offset between adjacent pieces of formwork facing material shall be Class C, unless specified otherwise.

4. Do not use metal cover plates for patching holes or defects in forms.

5. Provide sharp, clean corners at intersecting plans, without visible…
