Project Baptist Camp Bridge Maintenance

General Information

1.0 Scope of Work

This project requires the Contractor to perform work on Baptist Camp Bridge in the Tonto National Forest in the Payson district.

Baptist Camp Bridge is located on Forest Service Road 3675 at N 34° 21.236’ W 111° 05.880’, about 200 feet east of Tonto Creek Road (FR 289). Constructed in 1973 from timber sawn multi-girders on timber wall abutments, it is a one-lane bridge spanning Tonto Creek providing access to Tonto Rim Christian Camp. Overall length of the bridge is 41.0 feet with a maximum span of 40.0 feet, with a roadway width of 14.0 feet. The wooden deck is constructed from treated timber and formerly had steel running planks on the surface, but these planks were removed in August 2024 due to metal degradation and loose bolts.

Summary of Project Work Items Include the following:

Mobilization, Including Bonding Costs shall include payment for personnel, equipment, material, and incidentals to mobilize to and from the project site for the completion of this project.

Temporary Traffic Control includes all work necessary to design, permit, install and remove temporary traffic control for the site. Temporary traffic control plans shall be submitted to the COR for review and approval for the project site. Temporary Traffic Control is measured as a lump sum item.

Repair Wearing Surface includes all work necessary to install a timber wearing surface across the entire travel way and treat the new surface with wood preservative. This timber wearing surface consists of timber planks treated with copper naphthenate wood preservative.

Materials

New Wearing Surface Material:

Species such as Douglas Fir-Larch, Hemlock, and Spruce are acceptable. Edge-grain planks are preferred (growth rings form an angle of 45° to 90° with wide surface of the plank); when edge-grain material is not available, notify the Contract Officer (CO).

New Wearing Surface Treatment:

Waterborne preservatives should be used to treat the new lumber planks to AWPA use category UC4A. The following are acceptable waterborne preservatives: Alkaline Copper Quat (formulation A, B, C, or D), Copper Azole (formulation B or C), or Micronized copper azole (formulation C).

Process

Clean Bridge Deck:

Remove all material/debris from the deck surface. Removed material and debris must not be allowed to enter the stream.

Existing Deck Treatment:

Fill and seal existing deck to create even surface upon which to install timber wearing surface. See “Filler and Sealant Installation” below.

New Wearing Surface Configuration:

The new lumber wearing surface must consist of a series of rough-sawn lumber planks placed edge to edge across the deck width. The new wearing surface must cover the full travel width. Planks must be 10- to 12-in wide, 2.5- to 3-in thick, a minimum of 8-ft long, and oriented in the direction of traffic. The most economical arrangement is an alternating repetition of longitudinal planks with odd lengths at the bridge ends. End joints in adjacent planks should be staggered by 3-ft minimum (see Figure 1). When seasoned planks are used, a gap of ¼-in must be left between edge joints to allow for expansion. Tight edge joints are used for unseasoned (green) planks. At bridge approaches, bevel plank ends as depicted on Figure 2, unless the COR decides otherwise.

Figure 2: Beveled end-plank configuration

Wearing Surface Deck Attachment:

The connection must keep the planks firmly attached. Fasteners should be recessed below the road-way surface. Seal the recessed holes with mastic or caulk. To minimize decay and prevent splitting the existing deck, all fasteners must be placed in lead holes that are pre-bored and field treated with liquid wood preservative. Connection to the deck must employ 3/8-in diameter, 5.5-in long, zinc-plated or hot dipped galvanized lag screws, inserted vertically with a round steel cut washer under the head. Install lag screws using two pre-bored lead holes (Figure 3), one diameter hole for the shank (1/16-in larger than shank diameter) and bored to the depth of penetration of the shank. The lead hole dia-meter for the threaded portion, which is bored at least the length of the threads, should have diameter between 65% to 85% of the shank diameter. Plank attachment pattern is illustrated in Figure

4. When installing lag screws, the threaded portion must be inserted in the lead hole by turning with a wrench.

Filler and Sealant Installation includes all work necessary to apply wood preservative approved by the COR to the deck surface and applying a wood filler to the deck to remove ruts and ensure a smooth flat surface prior to installing the timber wearing surface. Conventional liquid wood preservatives should be applied by brushing, squirting, or spray-flooding the wood surface. Creosote heated to 150o to 200o F, pentachlorophenol (Penta), and copper naphthenate (Cu-Nap) may be used. Alternate oil-based products may be considered. The Contractor should submit the proposed preservative to the CO for approval. The wood surface should be thoroughly saturated with preservative so that all cracks and crevices are treated; however, care must be exercised to prevent excessive amounts from spilling or running off the surface and contaminating water or soil. This item also includes removing nails from the deck and adding new nails or implementing other COR-approved methods to stabilize the deck prior to installing the timber wearing surface.

Drainage Restoration includes all work and materials necessary to improve drainage on the upstream side, where water ponds.

Replace Timber Posts includes all work and materials necessary to replace missing and damaged timber posts and blocks attached to the bridge guardrail.

Repair Asphalt includes all work and materials necessary to repair bridge approaches to remove existing bumps and create a smooth surface. This will require removing the full width of the asphalt sections adjacent to the bridge approaches and replacing with new base aggregate and asphalt pavement. The new asphalt pavement shall provide a smooth transition to the bridge’s new timber wearing surface.

Resurface both approaches with a compacted layer of base aggregate 4” thick and asphalt concrete pavement 3” thick.

Base aggregate shall be provided and installed in accordance with Section 301 of FP-14. Asphalt concrete pavement shall be provided and installed in accordance with Section 403 of FP-14. Submit aggregate gradation and an asphalt job mix design to the CO for approval.

Replace Object Markers includes all work and materials necessary to install new object markers and posts to Manual on Uniform Traffic Control Devices (MUTCD) specifications and to replace any existing markers with new markers. Object marker locations need to be adjusted to end terminal locations. Removed material shall be disposed of off National Forest lands. New signs shall meet current MUTCD reflectivity standards.

The Contractor shall provide all labor, materials, equipment, and tools, including incidentals, necessary for the bridge maintenance work items and traffic control required within this project.
