� Client Address: National Forests in Alabama, Engineering Unit - Forest Service, 2946 Chestnut Street, Alabama 36107. Phone 334-241-8174; FAX 334-241-8101.

3. Specifications – Design all structures in accordance with AASHTO, subject to the modifications and additions contained herein. Use AASHTO material specifications if they exist; only use ASTM, FEDSPEC, MILSPEC, etc. if there is no appropriate AASHTO material specification.

4. Calculations - Perform all design calculations by a qualified (qualified meaning having a minimum 3 years of bridge design experience) registered Professional Engineer or by a qualified engineer working under the supervision of a qualified Professional Engineer.

Perform a thorough independent checks of all calculations (not merely a math check) and affix the professional seal (non-Federal Government engineers only) and signature of the responsible engineer on the final set of calculations. Submit two copy of the design calculations to the Forest Engineer for review and retention. Submit design calculations that are legible and fully annotated to facilitate review. Explain formulae and terms and cite all references.

5. Bridge Width – Use bridge widths that are consistent with design criteria, standards, and elements established for the transportation facility. Except when stated otherwise by the Forest Engineer, use the following roadway (curb-to-curb) width on Pine Glen bridge:

Single-lane Pine Glen Bridge: Use 18 feet as the minimum clear distance between curbs or railings. Use widths in excess of 32 feet only to accommodate curve widening, off-highway vehicles, pedestrian traffic and minor deviations (up to 2 feet) resulting from using standard modular structural units.

6. Drainage - On all road bridges, promote drainage by providing a minimum 1 percent crown, a minimum 1 percent gradient, or by superelevating the bridge, as appropriate.

7. Bridge Gradient - For all road bridges with concrete curbs, a minimum 1 percent grade from one end to the other is required to facilitate drainage off the bridge, unless otherwise specified. Grades in excess of 5 percent need to be carefully designed to ensure adequate clearance between the superstructure and substructure and to ensure that excessive gradient does not represent a hazard to users. Contact the Forest Engineer before using a grade greater than 5 percent.

B. SITE SURVEY AND SITE PLAN DEVELOPMENT

Prior to any design and a required by the specific task order, perform a site survey that records existing groundlines at a potential bridge site. Apply the following guidance to the survey and to the site plan, which documents the results of the survey:

1. Survey the site so that results are displayed in English units, with the drawing unit = 1” (inch). Note the date of the survey on ALL documents that display data from the site survey.

2. Survey the stream a minimum of 150 feet downstream and 300 feet upstream from the centerline of the existing bridge, or 5 bridge lengths above and below the proposed bridge location.

3. Location of the new bridge requires roadway re-alignment that maintains access to Pine Glen Campground. Coordinate with the Forest Engineer to ensure that an adequate area is selected for the topographic survey. Additional areas may need to be surveyed to establish temporary crossings for use during construction, as well.

4. Establish control points/reference points to be used during construction of the bridge that are outside the construction area, yet reasonably visible from the proposed alignment and work site. Clearly identify the location and nature of the control point on the site survey and final contract plans.

5. Establish a minimum of two permanent bench marks at location that would be used as control points during construction and be left in place for future reference. Assume local coordinates (x,y,elev.) to a the first permanent benchmark.

6. Show 1’-0” contour intervals and label every 5-foot contour on the site plan.

7. Display information accurately in 3D format. Do not reduce to 2D by setting elevation to “0.”

C. HYDROLOGY AND HYDRAULICS

Design the Pine Glen Bridge structure to pass a 100-year frequency flood with a minimum clearance of 5 feet between high water and the lowest point on the bottom of the superstructure, unless otherwise specified. Other clearance heights/freeboard will be specified, when needed. Refer any problems to the Forest Engineer for resolution.

Prior to design, perform a hydrologic and hydraulic analysis of the site. The goal of any hydrologic and hydraulic analysis at a site is to determine how the flow of water at the site will pass through the proposed structure, whether this can be accomplished without future blockage of the channel and/or waterway under the structure.

1. Adequately survey the stream, including profiles and cross-sections, to generate sufficient information to perform a HEC-RAS analysis of the stream at the bridge site.

Note the date of the survey on ALL documents. Note and survey grade control locations such as: steps, bedrock, logs, or rock clusters. Provide description labels identifying these features.

2. Identify the following: floodplain terraces and floodplain shape details, aggraded areas—gravel bars, islands, etc., degraded areas—scour pools, degraded channels, etc., bank erosion, bedrock locations, and the existing culvert (if applicable)—especially mark and survey the culvert invert locations for use as references points in the contract.

3. Visually observe any apparent high water elevations in the field.

4. In the field, visually establish a reasonable bank full width. The bank full width is defined as the width of the water surface, measured normal to the stream, at a normal flood level (Q2). Establish the bank full width at several locations, both upstream and downstream, so that a representative average bank full width is developed. Ensure that sites where bank full width is measured are outside the influence of any current structures, such as culverts.

5. Visually observe stream velocities at the site at the time of the visit.

6. Determine the Q2 and Q100 flows for the site using USGS Regression equations, stream gages, or any other pertinent or more applicable methods, including specific Forest analyses.

7. Determine a bank full width for site using HEC-RAS. Compare it to the visually observed bank full width. Establish a recommended bank full width to be used for the design of the stream cross-section at the bridge site.

8. Using HEC-RAS, determine a water surface profile and flow depth for the Q100 flow.

Confirm calculated flow depth with any observed high water marks at the site.

9. During analysis use a final stream cross-section used that emulates the natural stream bottom i.e. slightly curved/banked vs. a flat bottom across the stream width. Show several cross-sections along the surveyed length that typify the basic channel shape.

10. Include the following on other notes and sketches, as appropriate:

a. Existing bedforms—physical description, size of particles

b. Steps – spacing between, configurations, particle sizes

c. Reference reach location and description

d. Bank material composition description

e. Locations of utilities—overhead and underground

D. DESIGN SUBMITTALS

1. All design submittals shall meet the following requirements:

a. Investigate alternatives that are feasible on the basis of constructability and economics for the site. Use criteria identified in the specific Task Order for the contract.

Show these values on the drawings in a diagrammatic and tabular form for the tenth points of all spans. Base camber calculations upon an assumed age of 8 weeks.

8. Final Deck Elevation Diagram – For all bridges, provide a tabular diagram on the drawings which shows the design final deck surface elevations. Compute these final deck surface elevations for the same points as in #7 above, plus tenth points along each edge of deck and roadway centerline. Also compute final deck surface elevations at each end of the deck at all corners, roadway centerline, and line centerline. The connection of the floor beam to a pony truss system shall not be solely into the side of a tubular bottom chord without the use of additional stiffeners.

9. Concrete Curbs, Parapets and Curb End Blocks – Require concrete curbs to be cast at the precasting facility before being shipped. Construct concrete curbs, parapets and curb end blocks of air entrained 3500 psi Class A(AE) concrete.

10. Drains – Design drains to carry water off the superstructure considering the geometry of the structure, the site location and the expected weather conditions. Normally, place drains so that water discharges onto the riprap above the Q100 flow elevation. Drain designs should minimize plugging.

11. Deck Guard Angles – Use galvanized deck guard angles across the roadway portion of the concrete bridge deck at each end of the deck and at all deck joints. For prestressed concrete slabs, incorporate the deck guard angle into slab during casting.

As necessary, incorporate the deck guard angle into the back wall at the roadfill edge of the back wall.

12. Bearing Pads:

a. Design 60 durometer chloroprene (neoprene) bearing pads for each truss end, with a minimum thickness of 1/2 inch. Furnish one piece pads unless the design requires the pads to be laminated. Do not allow field punching of the pads to fit around any connections extending from the cap to the truss. Use joint filler material or expanded polystyrene under the back walls and above the cap, plus under the truss where there is no bearing pad, to seal the opening against earth and moisture. Pads are required even when beveled steel bearing plates are used.

b. Design bearing pads following AASHTO, using Load Group I (plus IB if spars are the rare design load), for the anticipated extreme temperature range of the trusss at the bridge site.

13. Reinforcing Steel - Use Grade 60 reinforcing steel.

G. DESIGN - SUBSTRUCTURE

1. Load Groups – Design substructures for Load Groups I, IB (if a spar is the rare design load), II, and III. For Load Group III, include loads caused by shear resistance in the bearing pads when the concrete is at its anticipated low temperature for the bridge site.

2. Seismic Considerations – Design all substructures and the connections between substructure and superstructure in conformance with the current AASHTO seismic design guidelines. For the normal single-span bridge this means ensuring adequate width of bearing seats and adequate strength of connections between trusses and substructures. In addition, normally build "earthquake blocks" into the tops of substructure caps at both ends of all spans. Use the seismic acceleration coefficient that would be used by the state bridge design section for the state in which the structure is to be located.

4. Load Ratings for New Bridge Designs

a. Complete design load ratings for new bridge in accordance with the applicable portions of the AASHTO. Submit with original final design drawings.

b. In the reports, include the completed rating forms followed by computations to support the ratings.

c. State that the report is based upon the assumption that the bridge(s) is in new condition and constructed in accordance with Pine Glen Bridge Replacement Drawing(s) (specify applicable drawings).

d. Provide two (2) copies of bridge load ratings for final bridge design, with set being individually bound and bearing the name, seal, and date of both rater and checker.

I. DRAWINGS - GENERAL LAYOUT AND FOUNDATION

1. General Layout

a. General Notes: Use the standard General Layout Sheet Notes, edited for the particular job.

b. Plan View: Show the following information in the Plan View of the bridge.

1) Stationing (increasing from left to right on the drawing) and elevation of beginning and end of bridge (BOB and EOB) on roadway centerline. When a wearing surface is present, note if the elevation is to the top of the wearing surface or to the top of the superstructure unit, to avoid confusion.

2) Add coordinates table (N,E,Z) for BOB and EOB, TBM, C/L Alignment and any other feature to assist in project staking.

3) Railing information not given on the standard railing sheets. This includes the specific alternate desired, when several are permitted (type finish -painted, galvanized, weathering steel; type approach rail end anchorage and end piece), variations from what is shown on the standard rail sheets (post spacing, bends in rail, different lengths of rail), distance from the first bridge rail and first approach guardrail posts from the ends of the bridge, etc. Label and dimension curved railing thoroughly to avoid fabrication errors, since railing shop drawings are normally not called for in contracts. Also show rail post spacing used as well as the rail pay length.

4) Skew the bridge as designed and laid out for. Normally only use standard skews such as 0, 15, and 30 degrees. For other skews, or skews in excess of 30 degrees, consult with the Forest Engineer before proceeding with the design.

5) Overall dimension of the bridge out-to-out as well as a dimension showing the span length.

6) Roadway width and lane widths/shoulder width, as appropriate.

7) Centerline roadway, centerline structure, and the offsets to chords of the roadway at BOB and EOB when a straight bridge is laid out on a curved roadway (as is normally the case). Label each of the above on the drawing.

c. Elevation View: Show the following information in the Elevation View of the bridge

1) Profile of the bridge projected from the right side of the bridge down into an elevation view. Show a simple bar graph near the detail with elevations marked at either 5 foot or 10 foot intervals and labeled “Elevations in Feet.”

2) The Q100 flow elevation and flow volume. Also list the minimum vertical clearance between the lowest portion of the superstructure and the Q100 predicted flow height in the General Note on Hydrology and Hydraulics.

3) The minimum bank full width.

4) Riprap size class, typical slopes, blanket thickness, elevation at top of riprap, bankfull width behind which riprap should be placed, and any other required dimension; also show cut-off trenches and keys. If the skew of the bridge exceeds 15 degrees, show an additional riprap detail normal to the stream centerline.

5) Gradient on the bridge.

6) The substructure type to be used at each abutment and an indication of required design bearing capacities for spread footings or design pile capacities and factor of safety for piling abutments. Include the word “design” in the capacity labels to avoid confusion with “ultimate” capacities.

For pile abutments, also show the minimum pile penetration required for scour (maximum pile tip elevation) as well as the anticipated pile tip for achieving design capacity. If pile shoes/rock tips are required, call out the specific part or approved equal. Label the abutments as “Abutment 1” and “Abutment 2.”
