To Use StayPanelTM Stay-in-Place Fascia Form
1. Stay-in-Place Fascia Forms (SIPFF) are typically
considered a means & methods provided
the inside face of the SIPFF is held to the outside
face of the proposed barrier line.
2. The contractor is responsible for all means &
methods and should propose the use of
SIPFFs early in the project to allow sufficient time for
review and acceptance by the owners representative
to avoid delays in the overall project schedule.
3. Standard SIPFFs can be used on both steel &
concrete fascia girders in most cases.
4. Standard SIPFFs come in three (3) types, ranging
from 0” to 36” soffit widths.

Type 1 Interior Hanger
When a bridge deck is designed with a fillet that extends a short distance away from the edge of the beam
(shown below), a Type 1 Interior Hanger is often selected. The hanger is designed to allow 1/8” maximum
clearance between the edge of the beam and the supporting 1/2” diameter coil bolt.
Turning the coil nuts will raise/lower the bridge deck formwork to grade. Any adjustment must always maintain
a thread penetration greater than 1/2” when measured from the top of the coil nut.
Full bearing of the end clips is required to maintain the safe working load of the hanger. Hangers must be
loaded equally on both sides to maintain formwork balance and prevent tipping.

Interior bridge deck hangers are typically fabricated using two steel end clips that have been welded to an
appropriate sized wire or formed metal connecting strut. In most cases, the end clips used on interior hangers
locate two coil bolts, one on each side of the bridge beam, at 90° to the top surface of the beam. These
hangers can be used on rolled structural steel beams, fabricated steel plate girders or precast/prestressed
concrete girders.
Sometimes there is a need for an interior half hanger that may be welded to the top flange of a steel beam,
attached to the shear studs on a steel beam or the rebar shear connectors on concrete girders. However,
most Department of Transportation (DOT) specifications prohibit any type of field welding to flanges in tension
zones, restricting welding to compression zones only. When this restriction is encountered, several types of
clip-on hangers are an available alternative.
Interior hangers are placed at predetermined locations along the top of the interior bay beams to support
bridge deck formwork loads, including the live load, dead load and formwork load. Once the formwork has
been completed and concrete is placed, the interior hangers support the weight of the freshly placed concrete.
After the concrete reaches a specified strength, the hardware and formwork are removed.
All interior hangers are identified by the shape of the end section. Unless noted, all end sections are designed
to accept a standard 1/2” diameter coil bolt/rod and nut. Since flanges will vary, it is essential to have the beam
dimensions before ordering.
For safety reasons, a qualified person must accurately calculate the loads for the interior hanger. Calculated
loads must be equal to or less than the safe working load. Contact the SureBuilt for assistance in determining
the applied loads and interior hanger spacing.

Exterior bridge deck hangers are typically fabricated using two steel end clips that have been welded to
an appropriate sized wire or formed metal connecting strut. In most cases, the end clips used on exterior
hangers locate two bolts, one at 90° to support the interior side and one at 45° to support the overhang side
of the formwork. These hangers can be used on rolled structural steel beams, fabricated steel plate girders or
precast/prestressed concrete girders.
Exterior hangers are placed at predetermined locations along the top of the outer bridge beams to support
bridge deck formwork loads, including the live load, dead load, formwork load and usually on the overhang,
a concrete conveyor and/or finishing machine load. Once the formwork has been completed and concrete is
placed, the interior hangers support the weight of the freshly placed concrete. After the concrete reaches a
specified strength, the hardware and formwork are removed.
All exterior hangers are identified by the shape of the end section. Unless noted, all end sections are designed
to accept a standard 1/2” diameter coil bolt/rod and nut. Since flanges will vary, it is essential to have the beam
dimensions before ordering.
For safety reasons, a qualified person must accurately calculate the loads for the overhang bracket. Calculated
loads must be equal to or less than the safe working load. Contact the SureBuilt Technical Service for
assistance in determining the applied loads and exterior hanger spacing.
Only use this hanger when the weight

Type BDH-3 Broached Exterior Hanger
The Type BDH-3 Broached Exterior Hanger has a 90° bend with a threaded end to support the interior
formwork and a 45° end clip to support the overhang bracket formwork. The interior side is a user specified
length with 1/2” threads. The exterior side end clip accepts 1/2” diameter coil rod and nuts.
For precast concrete beams, the interior leg is formed at 15° to support the formwork. A battered washer is
recommended for use beneath the interior formwork ledgers to allow for proper bearing.
The Type BDH-3 Broached Exterior Hanger is designed with a 1“ breakback. After the bridge deck has been
placed and interior formwork stripped, a pipe is placed over the threaded end to break off the hanger.

There are four different versions of the Standard Bridge Overhang Bracket along with two versions of the
Heavy Duty Bridge Overhang Bracket, providing the size and adjustment needed the varied bridge overhang
forming requirements on both structural steel and precast concrete beams.
The Standard version is designed for most common bridge beam conditions, with a 54” top channel and
telescoping 30” to 50” adjustable vertical strut.
The Deep version is designed for deeper bridge beams, with a 54” top channel and telescoping 50” to 70”
adjustable vertical strut. The Bridge Overhang Bracket is converted into the Deep version by using longer legs
for the lower vertical and diagonal components.
The Modified version is designed for shorter bridge beams, with a 54” top channel and single 16” to 28”
adjustable vertical strut. Remove the inner vertical leg on the Bridge Overhang Bracket to have the Modified
version. Using only the outer vertical leg, the bracket can be adjusted to a minimum vertical height of 16”. This
bracket is ideal for use on shallow steel or concrete beams.
The Junior version is designed for limited space
conditions, with a 27” top channel and single 16” to
28” adjustable vertical strut.
Bridge Overhang Bracket
The Bridge Overhang Bracket adjusts to fit both
structural steel and precast concrete beams. The
size and shape of a bracket is adjusted by changing
the vertical and diagonal legs to meet the specific
overhang requirements. Brackets can be preset
on the ground, then moved into position, to speed
forming operations.
Both the vertical and diagonal legs have adjustment
holes spaced at 2” increments, allowing the legs to
be adjusted so the diagonal leg will transfer the load
from the end of the bracket to the bottom flange of
the beam. An adjusting nut at the outboard end of the
bracket is used to adjust the bracket to final grade.
A coil bolt attached to the exterior hanger passes
through a Bolt Holder located along the bottom of
the horizontal channel. The Bolt Holder must be
relocated for each project so the coil bolt is at a 45°
angle to the top flange of the beam and bearing
against the bottom side of the channel to support the
bracket load.
An Extension channel for wider overhangs, Guard
Rail Pocket for 2×4 lumber uprights, and Wall Plate
for wall mounting, are options adding to the versatility
of the Bridge Overhang Bracket.

Heavy Duty Bridge Overhang Brackets
The Heavy Duty Bridge Overhang Brackets can be used with an appropriate 3/4” exterior hanger, such as
the Type 9-A and 9-AB. Heavy Duty Bridge Overhang Brackets are fabricated with nail holes in the top of the
horizontal member for securing the required lumber nailer to the bracket.
A guard rail receptacle, which allows for attaching a 2” x 4” guard rail post, is built into the outboard end of the
bracket’s horizontal member. The bracket can be easily and quickly preset on the ground and then set in place
as needed. An outboard adjustment nut controls the vertical movement of the outboard end of the bracket to
accommodate setting the overhang formwork to final grade.
Overhang Brackets are usually adjusted to the proper grade during the normal “dry run” operation. Typically,
the overhang forms are set 1/4” to 3/8” above finished grade to compensate for dead load deflection. The
Heavy Duty Bridge Overhang Bracket is designed for maximum adjustment and strength to meet the varied
overhang forming requirements of the various State D.O.T.
Conversion Kit
The standard Bridge Overhang Bracket is quickly
converted to a Deep version by replacing the
telescoping vertical and diagonal legs with the
Conversion Kit. This substitution changes the
adjustment range from 30/50 to 50/70.
Extension Channel
The Extension Channel attaches to one side of
the Bridge Overhang Bracket to extend the usable
working length. The Extension Channel is only used
to support a walkway so the entire length of the
Bridge Overhang Bracket can be used for formwork
support.
Guard Rail Bracket
The Guard Rail Bracket bolts to either the Bridge
Overhang Bracket or the Extensions Channel. This
provides a secure location for a lumber 2×4 post for
the guard rails along the edge of bridge formwork.
Wall Plate Assembly
The Wall Plate Assembly is an adjustable attachment
plate that is fastened to a 3/4” insert (Coil or NC type)
that has been cast into a concrete wall or precast
bridge beam. The Bridge Overhang Bracket is then
bolted through the sleeve of the Wall Plate Assembly
to support the formwork.
The serrated face of the plate and washer provides
the height adjustment when fastening the Wall Plate
Assembly to the 3/4” insert. Unbolting the Bridge
Overhang Bracket from the Wall Plate Assembly, then
removing the Wall Plate Assembly, simplifies stripping
and removal.

When selecting a trial Hanger and Bridge Overhang Bracket spacing, and the selected spacing is:
•
•
•
•
•
Wheel Spacing equal to or less than 1.0, multiply Wheel Load by a Screed Load Factor of 1.0
Wheel spacing 1.0 and 2.0, multiply Wheel Load by a Screed Load Factor of 1.5
Wheel Spacing 2.0 and 3.0, multiply Wheel Load by a Screed Load Factor of 1.7
Wheel Spacing 3.0 and 4.0, multiply Wheel Load by a Screed Load Factor of 1.9
Wheel Spacing greater than 4.0, multiply Wheel Load by a Screed Load Factor of 2.3
To determine total Screed Load (S) applied to an overhang bracket, use this approximation or the next highest
incremental value for the total load per bracket when referring to the spacing tables.
The tables shown on the following pages indicate the maximum hanger and Bridge Overhang Bracket spacing
for various slab thicknesses and screed loads, the type of hanger and bracket required, and the proper bracket
dimensions needed to safely obtain the spacings listed.
The two basic types of bridge deck finishing/screed machines are illustrated below:
8 Wheel Machine 4 Wheel Machine
Hanger and Bridge Overhang Bracket spacing example:
•
•
•
•
Steel beam is 40” deep with 1” flange
Concrete slab is 8” thick (157 psf design load) with 3’-0” overhang
Using Bridge Overhang Bracket and Type 8A Hanger (4,500 lbs)
Screed machine is 8-wheel type, with 1’-6” wheel spacing, at 650 lbs/wheel load
The “D” dimension in the spacing table is the beam depth, less the flange thickness, forming lumber thickness,
and 2” to 6” of additional clearance.
Determine the Screed Load Factor:
4’-0” (trial bracket spacing)
=
2.66 is a Screed Load Factor of 1.7 (shown above)
1’-6” (screed wheel spacing)
Determine the screed load per bracket:
(Screed load/wheel)(Screed Load Factor)
=
650 lbs x 1.7
=
1105 lbs Screed load per bracket
Refer to the hanger spacing table for a steel beam with 3’-0” overhang. Find the 8” slab thickness (157 psf
design load), 30” bracket D dimension and 4500 lb hanger. Follow the row until it intersects with the vertical
column showing the screed load per bracket. In this example, the maximum allowable hanger and bracket
spacing is 3’-3”.

The Wall Plate Assembly is an adjustable attachment plate that is fastened to a 3/4” insert (Coil or NC type)
that has been cast into a concrete wall or precast bridge beam. The Bridge Overhang Bracket is then bolted
through the sleeve of the Wall Plate Assembly to support the formwork.
The serrated face of the plate and washer provides the height adjustment when fastening the Wall Plate
Assembly to the 3/4” insert. Unbolting the Bridge Overhang Bracket from the Wall Plate Assembly, then
removing the Wall Plate Assembly, simplifies stripping and removal.
The tables shown on the following pages indicate the maximum Wall Plate and Bridge Overhang Bracket
spacing for various slab thicknesses and screed loads, the type of insert and bracket required, and the proper
bracket dimensions needed to safely obtain the spacings listed.

Joist Spacing
The spacing of the joists supporting the plywood formwork, is a function of the type and thickness of plywood.
The number of joists supporting each piece of plywood and the direction of the plywood face grain in relation to
the joists, determines the center-to-center joist spacing.
Joist centers have been calculated using standard engineering principles that determine the maximum joist
spacing based on plywood bending, deflection and rolling shear (in the plane of the plywood plies). Once the
centers have been calculated, the safe joist spacing is arranged in tables.
For concrete formwork, virtually any exterior plywood can be used, as all exterior plywood is produced using
waterproof glue. However, the plywood industry produces special plywood called Plyform®, created especially
for use as concrete formwork. (Plyform is a proprietary product name and is used for specific products, which
bear the trademark of the APA – The Engineered Wood Association.)
The section properties and allowable stresses shown below, were used to develop the safe joist spacing charts
using information taken from the Concrete Forming Design/Construction Guide (2004) published by the APA

Ledger Spacing
The center-to-center spacing of ledgers used to support joists, is a function of the species, grade and size of
joist lumber selected for use, as well as the joist centers and number of ledgers used in supporting each length
of joist.
Nominal lumber sizes are used in the joist and ledger descriptions, but calculations are based on lumber
finished on all four sides (S4S). Ledger centers are calculated by checking bending, deflection and horizontal
shear. Once the ledger centers are determined, the joist centers and ledger spacing are arranged in tables.
The adjusted stresses are used in all joist and ledger calculations and are based on the use of Southern Pine,
Grade #2 or equivalent strength lumber:

available from American Forest & Paper Association.
The maximum spacing between double ledgers should no more than 1/4” greater than the nominal diameter of
the coil bolt or coil rod being used. When more space is allowed between the ledgers, the ledgers may crush or
the flat washers may deflect/bend causing the formwork to fail.

Welding Half Hangers
Half Hangers may be welded to steel beams or rebar stirrups, but preheating or other procedures may be
required for a sound weld. Contact a welding supply dealer to determine the required welding procedures.
Warning: Welding may alter the strut or rebar stirrup. Use the tables as a guide to determining the
approximate strength of the welded connection. Field tests should be performed to determine the actual safe
working load for each welded hanger condition.
