    FALSEWORK AND FORMWORK
    (11-30-23)
    GENERAL
    Use this Special Provision as a guide to develop temporary works submittals required by the
    Standard Specifications or other provisions; no additional submittals are required herein. Such
    temporary works include, but are not limited to, falsework and formwork.
    Falsework is any temporary construction used to support the permanent structure until it becomes
    self-supporting. Formwork is the temporary structure or mold used to retain plastic or fluid
    concrete in its designated shape until it hardens. Access scaffolding is a temporary structure that
    functions as a work platform that supports construction personnel, materials, and tools, but is not
    intended to support the structure. Scaffolding systems that are used to temporarily support
    permanent structures (as opposed to functioning as work platforms) are considered to be falsework
    under the definitions given. Shoring is a component of falsework such as horizontal, vertical, or
    inclined support members. Where the term “temporary works” is used, it includes all of the
    temporary facilities used in bridge construction that do not become part of the permanent structure.
    Design and construct safe and adequate temporary works that will support all loads imposed and
    provide the necessary rigidity to achieve the lines and grades shown on the plans in the final
    structure.
    MATERIALS
    Select materials suitable for temporary works; however, select materials that also ensure the safety
    and quality required by the design assumptions. The Engineer has authority to reject material on
    the basis of its condition, inappropriate use, safety, or nonconformance with the plans. Clearly
    identify allowable loads or stresses for all materials or manufactured devices on the plans. Revise
    the plan and notify the Engineer if any change to materials or material strengths is required.
    DESIGN REQUIREMENTS
    (A) Working Drawings
    Provide working drawings for items as specified in the contract, or as required by the Engineer,
    with design calculations and supporting data in sufficient detail to permit a structural and safety
    review of the proposed design of the temporary work.
    On the drawings, show all information necessary to allow the design of any component to be
    checked independently as determined by the Engineer.
    When concrete placement is involved, include data such as the drawings of proposed sequence,
    rate of placement, direction of placement, and location of all construction joints.
    When required, have the drawings and calculations prepared under the guidance of, and sealed
    by, a North Carolina Registered Professional Engineer who is knowledgeable in temporary
    works design.

    Henderson County
    If requested by the Engineer, submit with the working drawings manufacturer’s catalog data
    listing the weight of all construction equipment that will be supported on the temporary work.
    Show anticipated total settlements and/or deflections of falsework and forms on the working
    drawings. Include falsework footing settlements, joint take-up, and deflection of beams or
    girders.
    As an option for the Contractor, overhang falsework hangers may be uniformly spaced, at a
    maximum of 36 inches, provided the following conditions are met:
    Member Member Max. Overhang Max. Slab Edge Max. Screed

    Overhang width is measured from the centerline of the girder to the edge of the deck slab. For
    Type II, III & IV prestressed concrete girders (PCG), 45-degree cast-in-place half hangers and
    rods must have a minimum safe working load of 6,000 lbs.
    For MBT prestressed concrete girders, 45-degree angle holes for falsework hanger rods shall
    be cast through the girder top flange and located, measuring along the top of the member, 1’-
    2 ½” from the edge of the top flange. Hanger hardware and rods must have a minimum safe
    working load of 6,000 lbs.
    For link slabs, the top of girders directly beneath the link slab shall be free of overhang
    falsework attachments or other hardware. Submit calculations and working drawings for
    overhang falsework in the link slab region.
    The overhang bracket provided for the diagonal leg shall have a minimum safe working load
    of 3,750 lbs. The vertical leg of the bracket shall extend to the point that the heel bears on the
    girder bottom flange, no closer than 4 inches from the bottom of the member. However, for
    72-inch members, the heel of the bracket shall bear on the web, near the bottom flange
    transition.
    Provide adequate overhang falsework and determine the appropriate adjustments for deck
    geometry, equipment, casting procedures and casting conditions.
    If the optional overhang falsework spacing is used, indicate this on the falsework submittal and
    advise the girder producer of the proposed details. Failure to notify the Engineer of hanger type
    and hanger spacing on prestressed concrete girder casting drawings may delay the approval of
    those drawings.

    Henderson County
    Falsework hangers that support concentrated loads and are installed at the edge of thin top
    flange concrete girders (such as bulb tee girders) shall be spaced so as not to exceed 75% of
    the manufacturer’s stated safe working load. Use of dual leg hangers (such as Meadow Burke
    HF-42 and HF-43) are not allowed on concrete girders with thin top flanges. Design the
    falsework and forms supporting deck slabs and overhangs on girder bridges so that there will
    be no differential settlement between the girders and the deck forms during placement of deck
    concrete.
    When staged construction of the bridge deck is required, detail falsework and forms for screed
    and fluid concrete loads to be independent of any previous deck pour components when the
    mid-span girder deflection due to deck weight is greater than ¾”.
    Note on the working drawings any anchorages, connectors, inserts, steel sleeves or other such
    devices used as part of the falsework or formwork that remains in the permanent structure. If
    the plan notes indicate that the structure contains the necessary corrosion protection required
    for a Corrosive Site, epoxy coat, galvanize or metalize these devices. Electroplating will not
    be allowed. Any coating required by the Engineer will be considered incidental to the various
    pay items requiring temporary works.
    Design falsework and formwork requiring submittals in accordance with the current edition of
    AASHTO Guide Design Specifications for Bridge Temporary Works except as noted herein.
