1. Install forms substantially free of surface defects.

J. Formwork Loads on Grade

DOC A - Phase II 031000 -11 CONCRETE FORMWORK

1. Where loads from formwork bear on grade, provide suitable load-spreading devices for adequate support and to minimize settlement. In no event shall frozen ground or soft ground be utilized directly as the supporting medium.

K. Footings and Grade Beams:

1. Provide forms for footings and grade beams if soil or other conditions are such that earth trench forms are unsuitable.

2. When trench forms are used, provide an additional 1” (25mm) of concrete on each side of the minimum design profiles and dimensions indicated.

L. For slabs-on-grade, secure edge forms in such a manner as to not move under weight of construction loads, construction and finishing equipment, or workers.

3.2 REMOVING FORMS

A. Formwork not supporting weight of concrete, such as sides of beams, walls, columns, and similar parts of the work, may be removed after cumulatively curing at not less than 50 o F

(10 o C) for 12 hours after placing concrete, provided concrete is sufficiently hard to avoid damage by form-removal operations, and provided curing and protection operations are maintained after removal of formwork.

B. Formwork supporting weight of concrete, such as beam soffits, joists, slabs, and other structural elements, may not be removed until concrete has attained at least 75% of design compressive strength as proven by cylinder test. If stripping occurs before [3] days, 100% strength must be achieved.

1. Provide reshores as required per ACI 347.

2. Determine potential compressive strength of in-place concrete by testing field-cured specimens representative of concrete location or members.

C. Remove formwork progressively using methods to prevent shock loads or unbalanced loads from being imposed on structure. Comply with ACI 347.

D. Loosen forms carefully. Do not wedge pry bars, hammers, or tools against concrete surfaces.

E. Reshore structural members where required due to design requirements, construction requirements, or construction conditions.

1. Reshore on same day shoring and forms are removed.

F. Whenever formwork is removed during the curing period, the exposed concrete shall be cured per requirements of Section 033000.

G. All wood formwork, including that used in void spaces, pockets and other similar places shall be removed.

H. Form tie holes shall be filled as per approved samples submitted to the Architect and Engineer.

I. The Contractor shall assume responsibility for all damage due to removal of the forms.

DOC A - Phase II 031000 -12 CONCRETE FORMWORK

3.3 RE-USING FORMS

A. Before forms can be re-used, surfaces that will be in contact with freshly poured concrete must be thoroughly cleaned, damaged areas repaired, and projecting nails withdrawn.

1. Split, frayed, delaminated or otherwise damaged form-facing material will not be acceptable.

2. Apply new form release agent on re-used forms.

B. When forms are extended for successive concrete placement, thoroughly clean surfaces, remove fins and laitance, and tighten forms to close joints. Align and secure joints to avoid offsets.

C. Forms for exposed concrete may be reused only if the surfaces have not absorbed moisture and have not splintered, warped, discolored, stained, rusted or peeled, subject to acceptance by the Design Professionals. The Design Professionals reserve the right to require the

Contractor to remove and reconstruct such formwork as will produce subsequent areas that are acceptable. Do not use "patched" forms for exposed concrete surfaces, unless approved by the Design Professionals.
