Common use of REMOVING AND REUSING FORMS Clause in Contracts

REMOVING AND REUSING FORMS. A. Formwork for sides of beams, walls, columns, and similar parts of the Work that does not support weight of concrete may be removed after cumulatively curing at not less than 50 deg F (10 deg C) for 24 hours after placing concrete. Concrete has to be hard enough to not be damaged by form-removal operations, and curing and protection operations need to be maintained. B. Clean and repair surfaces of forms to be reused in the Work. 1. Split, frayed, delaminated, or otherwise damaged form-facing material are unacceptable for exposed surfaces. 2. Apply new form-release agent. C. When forms are reused, clean surfaces, remove fins and laitance, and tighten to close joints. 1. Align and secure joints to avoid offsets. 2. Do not use patched forms for exposed concrete surfaces unless approved by Architect.
