3.1.1 Use forms that conform to ACI 347. Fabricate with facing materials that produce the specified tolerance requirements of ACI Special Publication No. 4, Formwork for Concrete, produce true surfaces, sharp corners and true lines and are free of offsets, ridges, bulging, waves and concave or convex areas. Forms must be sufficiently rigid to withstand construction loads and vibration and to prevent displacement or sagging between supports. Construct forms such that the concrete and/or exposed rebar (dowels) will not be damaged by their removal. The Contractor must be entirely responsible for the adequacy of the forming system.

3.1.2 Use regular and uniform pattern: long dimensions of panels must be vertical; joints horizontal, vertical, and aligned; form ties uniformly spaced and aligned in horizontal and vertical rows.

3.2 PREPARATION

3.2.1 Forms must not be reused if there is any evidence of surface wear and tear or defects which would impair the quality of the surface. All surfaces of forms and embedded materials must be cleaned of any mortar from previous concreting and of all other foreign material or water before coating is placed on them.

3.2.2 Forms must be coated in accordance with manufacturer's recommendations before the form or reinforcement is placed in final position. Surplus coating on form surfaces, or any coating on reinforcing steel and construction joints must be removed before placing concrete.

3.3 INSTALLATION, REMOVAL, AND SHORING

3.3.1 Installation of forms will comply with the following requirements:

October 2025 Specification 031000 | 4

Forms must be sufficiently tight to prevent loss of mortar from the concrete, set true to the lines and elevations indicated on the Drawings, tied, and braced to remain true during and after concrete placement within tolerances of Part 2.1 of this Specification. The Project Manager or Hillsborough County Inspector may at any time condemn any section or sections of forms found deficient in any respect, and such form must be promptly removed and replaced.

No wooden spreaders must be allowed to remain in the concrete.

Place chamfer strips in forms to bevel all corners, edges, joints and other structural elements exposed to views, including use of dummy chamfer and false joints to provide neat and uniform appearance. Exposed corners and edges must have 3/4-inch by 3/4-inch with 45- degree chamfers, unless otherwise indicated on the Construction Drawings.

Provide temporary openings at the base of wall forms and at the other points when necessary to facilitate cleaning and inspection immediately before depositing concrete.

Secure in position wedges used for final alignment and items to be embedded in concrete.

Forms for keyways must be prepared in advance of pouring concrete. Keyway forms in slab edges and vertical wall joints must be rigidly secured in place before the concrete is poured. Forms for keyways for horizontal joints in walls may be placed at the conclusion of the pour, but proper provision must be made for obtaining and holding the full depth and form of the keyway.

3.3.2 Adjustment of forms will comply with the following requirements:

Positive means of adjustment must be provided to permit realignment or readjustment of shores if excessive settlement occurs.

A pair of wedges may be used at the top or bottom of shores, but not at both ends, to facilitate vertical adjustment, to correct uneven settlements, or to facilitate dismantling of the formwork.

Screw jacks for pipe shores or scaffold-type shoring may be used both top and bottom so long as they are secured by the shore or scaffold leg against loosening or falling out, to avoid lateral deflections.

During and after concreting, but before initial set of the concrete, the elevations, camber, and plumbness of formwork systems must be checked, using telltale devices.

Appropriate adjustments must be promptly made where necessary. If, during construction, any weakness develops and the formwork shows any undue settlement or distortion, the work must be stopped, the affected construction removed if permanently damaged, and the formwork strengthened.

3.4 EMBEDDED ITEMS

3.4.1 Items to be embedded in concrete must be free from oil or foreign matter that would weaken the bonding of the concrete to these items.

3.4.2 Install in the formwork requisite inserts, anchors, sleeves, and other items specified under other sections of these Specifications. Close ends of conduits, piping, and sleeves embedded in concrete with caps or plugs.

3.4.3 Concrete pads, curbs, pedestals, and similar means devised by the Contractor to support the forms will be subject to review by the Project Manager or Hillsborough County Inspector.

3.4.4 Before depositing concrete, check the location and support of items which are to be wholly or partially embedded.

October 2025 Specification 031000 | 5

3.4.5 Place reinforcement so that there will be a clear distance of at least two inches between the reinforcement and any anchor bolts or other embedded metal work.

3.5 FIELD QUALITY CONTROL

3.5.1 Construct elements to meet the allowable tolerances of the dimensions, elevations, and positions specified in Specification 033000.

3.5.2 Deposit concrete only when the forms and placement of the reinforcement has been checked and approved by the Project Manager or Hillsborough County Inspector. The Contractor must provide notice to the Project Manager or Hillsborough County Inspector at least 24 hours in advance of any contemplated concrete pour.

3.5.3 Failure of the forms to comply with the requirements specified herein, or to produce concrete complying with the requirements of this Section, in the opinion of the EOR, the Project Manager, or Hillsborough County Inspector, will be grounds for rejection of that portion of the form/concrete work. Rejected work must be repaired or replaced as directed by the EOR or Hillsborough County Inspector at no additional cost to the County. Such repair or replacement will be subject to the requirements of this Section and approval of the EOR.

3.6 JOINTS

3.6.1 Unless otherwise directed, make contraction, expansion, and construction joints only where shown.

3.6.2 Continue reinforcing steel and wire fabric across construction joints which are not indicated as being free to move.

3.7 REMOVAL OF FORMS, FALSE WORK, AND CENTERING

3.7.1 Maintain forms, false work, and centering in place until the concrete has attained the minimum percentage of the design strength and met the criteria specified below in both 3.7.2 and 3.7.3. The design strength must include the strength of the concrete structural member(s) to carry their own weight and any loads to which they will be subjected without exceeding the permissible concrete stresses and without deforming.

3.7.2 Maintain forms, false work, and centering in place until the concrete has attained the minimum percentage of specified design strength listed in the following table and 3.7.3

Minimum Percent of Specified Design Strength

Structural Member Schedule 1 Footings; Inverts, sides of beams, slabs and girders;

Slabs and beams on grade

40%

Open cut structure exterior walls; Retaining walls 60% Soffits and beams; Slabs and girders under 20 feet clear span between supports

80%

Cantilevers and intersecting sections 90%

3.7.3 Maintain forms, false work, and centering for listed and non-listed members until the concrete has attained the minimum specified strength and at least one of the following criteria has been met:

October 2025 Specification 031000 | 6

The Project Manager has approved calculations showing the anticipated concrete strengths at the time of the proposed early removal based on:

a) Ratio of dead load over live load;

b) Span, height and shape;

c) Ratio of rise over span;

d) Shoring;

e) Loads, resultant stresses, and deformations to which the concrete and reinforcing steel will be subject at the time of removal, subsequent to the removal and until the concrete has attained its design strength;

f) Prevailing site conditions.

The concrete strength attained prior to form removal has been determined from tests of cylinders cured adjacent to and under the same conditions as the placed concrete.

Three test cylinders taken by the test laboratory have been tested by an independent testing laboratory retained by the Contractor and approved by the Project Manager or Hillsborough County Inspector and the tests performed in accordance with Specification 033000.

3.7.4 Do not alter the loading conditions on the concrete after the removal of the forms if it results in exceeding the permissible stresses and deformation at the attained concrete strengths.

3.7.5 If formwork is removed from a surface prior to the specified curing period, provide curing and protection per Specification 033000, Part 3.6.
