Municipality of the County of Annapolis Granville Ferry Forcemain

Support Replacement Details

1. Introduction

In Granville Ferry, Annapolis County, there is a force main that is supported by braced steel

members that are anchored into the side of a bridge deck. The bridge spans across very

turbulent sea water, and the corrosive environment has deteriorated the existing supports.

Hatch was engaged by Annapolis County to provide a replacement design for the supports. A

site visit was conducted on Wednesday, March 11th to assess the structure condition and

take some site measurements.

1.1 Site Findings and Design Assumptions

Below is a brief list of findings from the site inspection, discussions with NSTIR, and

information provided.

• The bridge deck is one uniform concrete structure, and the sidewalk which is integral with

the deck was measured to be approximately 1800 mm from the outer edge of the bridge.

This was later confirmed to be 6’-6” (~2000 mm) in drawings of the existing structure (see

Figure 1)

Figure 1 – Concrete Cross Section at Bracket Location

H-362333-SPE-0006, Rev. 1

Page 2 of 7


• The ownership of the bridge varies based on its depth. The County owns the top 400 mm

of the deck, and below that becomes the jurisdiction of NSPI due to embedded

infrastructure. As such, design should be limited to the top 400 mm of the deck if

possible. Coordination with NSPI should be part of the designed solution in order to

ensure the satisfaction of all parties.

• Existing supports are made of members which appear to be 76 x 76 angles, and are

composed of a vertical member anchored to the bridge deck with a main "cantilever"

member at its top. There is a diagonal brace between the vertical member and the

cantilever. See Figure 2 for a photo showing typical brackets.

Figure 2 – Existing Forcemain Support Brackets

• The force main is 200 mm diameter PVC with insulation, and is assumed to be filled with

water for the purposes of bracket analysis. An acting load of 10% of the water weight will

be applied horizontally to approximate the effects of moving liquid through the pipe.

• Steel supports are typically spaced 1800 mm, though some were measured slightly

higher. A spacing of 1800 mm will be assumed for the purposes of analysis and

specification of new support brackets.

The nature of the site did not allow for precise measurements of all elements. As such, some

additional assumptions have been made regarding the design, stated below.

• Condition of concrete looked good, but will conservatively be considered as "cracked" for

the purposes of anchor design.

• Grade of concrete is unknown, and will be assumed conservatively to be 25 MPa.

• Dimensions of concrete cross section for the purposes of anchor design are based on the

cross section shown in Figure 1, rather than measured site dimensions (field verification

was unobtainable during visit).

H-362333-SPE-0006, Rev. 1

Page 3 of 7


• Insulation details are unknown. 50 mm insulation with a 20 gauge galvanized jacket was

assumed for the purposes of this design.

2. Replacement Design

As a broad statement for the new construction, all material for the new bracket construction

and anchorage, as well as pipe guides should be galvanized. Typically stainless steel would

be suitable or even preferred for this application given the proximity to turbulent saltwater, but

assuming that the jacket on the force main is galvanized, contact with stainless steel would

induce undesirable galvanic activity between the jacket and the new supports.

In the interest of staying close to the original design, 76 x 76 x 6.4 angles were used for the

primary members, with a 51 x 51 x 6.4 angle brace. A STAAD model was constructed for

analysis using angle lengths based on pipe guide requirements for a 200 mm PVC pipe with

50 mm of insulation and a jacket. As such, the length of angle required for support is

approximately 400 mm as a minimum.

In order to include a 45 degree diagonal brace to the main support member, the vertical

member also needs to be 400 mm long as a minimum. The length of the brace can be

fabricated to end slightly within the 400 mm minimum lengths (similar to the existing brackets)

without significant impact on the structure. See Figure 3 below for a rough render and

dimensions of the support bracket as described.

Figure 3 – Support Bracket STAAD Render and Dimensions

Design loads within the structural model were based on the water filled, insulated PVC force

main supported every 1800 mm. Lateral loads for water movement through the pipe and wind

on the frame were also applied.

STAAD output indicated that the selected member sizes would be adequate to resist the

applied loading, and the 76 mm wide flanges provide sufficient base material for all drilled

holes needed for anchorage and pipe guides.

H-362333-SPE-0006, Rev. 1

Page 4 of 7


2.1 Anchor Design

Reactions from the STAAD model as well as alternate hand calculated reactions were used

for the design of new Hilti adhesive anchors. HIT-ICE adhesive was selected based on the

application conditions and location. The condition of the concrete was conservatively set as

cracked, with a compressive strength of 25 MPa.

Relevant edge distances for anchor strength reduction factors were based on the provided

drawings. It was assumed that anchors would be a minimum of 150 mm from any concrete

edge, and that two anchors would be used for each support with a minimum spacing of 250

mm. It was determined that 3/8” Galvanized Hilti HAS Rods using HIT-ICE adhesive at an

150 mm embedment are suited for the loading imposed by the brackets.

2.2 Other Project Considerations

The task in question is potentially related to the ongoing Broadband project within the

municipality. The question was raised as to whether the supports could hold and added cable

tray for use in running broadband fiber across the water.

Loading for a 150 mm wide cable tray was added to the STAAD model on an extension of the

main support member and it was determined that if this is the preferred course of action, the

bracket is suitable for this addition. See Figure 4 below for a rough render of this modification

to the bracket.

Figure 4 – STAAD Render of Support Bracket with Extension for Cable Tray

2.3 Pipe Straps and Shield Plates

Pipe straps, with similar function as the existing conditions (Figure 2), will be required for

installation at each bracket. New shield plates (minimum 300 mm long and minimum 1/3 of

the pipe circumference wide), between the bottom of the pipe insulation and top angle

member of the brackets, to distribute the loading of the pipe are also required for each

bracket. The straps, shield plates and all other appurtenances required for their installation

shall be hot dipped galvanized finish.

The following figures provide a visual of two acceptable products for the straps and one for

the pipe shield. All products shown are fabricated by “Taylor Pipe Supports” and reference

H-362333-SPE-0006, Rev. 1

Page 5 of 7


their catalogue “Pipe Support Products” dated April 2019. Install straps and shields as per

manufacturer’s specifications. Threaded rod, or bolts, sized to fit the appropriate drilled holes

in the brackets, with nuts and washers for steel connections are required.

Figure 5 – #46 Hold Down Clamp

Figure 6 – #14Z Standard U-Bolt

Figure 7 – #69 Protection Shield

As the straps themselves will not be subject to significant lateral loading, there is a range of

options available to the contractor to provide the function specified. The contractor may

choose to provide shop drawings for review and with the engineer’s written approval, proceed

with said option.

H-362333-SPE-0006, Rev. 1

Page 6 of 7


3. Recommendations

New support brackets shall be hot dipped galvanized steel and spaced no more than 1800

mm (6 ft) from each other.

The main support members are 76 x 76 x 6.4 angles, with a 51 x 51 x 6.4 angle brace. Main

members are 400 mm long as a minimum to accommodate pipe guide requirements for a

force main of this size, with an optional extension to the main member to accommodate cable

tray for future works.

Anchorage for the brackets consists of 3/8” Hilti Galvanized HAS Rods, using HIT-ICE

adhesive at an embedment of 150 mm. Two anchors are to be used at each bracket, to be

spaced 250 mm from each other as a minimum, and anchors should be a minimum of 150

mm from any concrete edge. Anchors shall be installed by a Hilti certified installer under

proper install conditions for the adhesive and anchor specified.

Pipe strap and shield are to be installed at each bracket location. Refer to Section 2.3 for

additional details.
