CONSTRUCTION NOTES:

RIPRAP SLOPE ARMORING

PREFABRICATED STEEL BRIDGE SUPERSTRUCTURE:

Prefabricated steel superstructure design must be a truss configuration similar to that shown on the drawings. the bridge shall maintain the clearances above high water indicated on the bridge elevation. the bridge cross-section shall be determined by the contractor but shall provide the width and railing details indicated on the bridge typical section. the contractor shall determine truss height and the location of the deck, but shall maintain a u frame bridge structure. overhead lateral bracing is unacceptable. All related details such as profile, abutment details, bearings, and timber decking shall be the responsibility of the contractor to finalize and construct.

the prefabricated steel bridge superstructure and associated details including timber components shall be designed under the direction of a registered professional engineer.

the completed design, drawings, and specification package shall be submitted to the contracting officer for review and approval.

DESIGN: The design of all prefabricated steel bridge superstructure elements shall comply with the AASHTO "Guide Specifications for Design of Pedestrian Bridges", 1997 Edition, or latest version, and AASHTO Standard Specifications for Highway Bridges, 17th Edition, or latest version.

MATERIALS: Use steel shapes, plates and bars of weathering steel conforming to AASHTO M270, GRADE 50W (ASTM A588 or ASTM A242) or ASTM A847 for square and rectangular tubing. Minimum steel thickness shall be as specified in the guide specifications for design of pedestrian bridges. Use high strength bolts conforming to AASHTO M164, (ASTM A325), TYPE 3, unless noted otherwise. use malleable iron washers against wood.

STEEL FABRICATION: The prefabricated steel bridge superstructure shall be fabricated by an aisc certified plant - simple steel bridges or complex steel structures.

When structural steel is to be welded, the welding procedure shall be in accordance with AWS D1.5 and shall be suitable for the grade of steel and intended use or service.

ERECTION PLAN: The contractor shall submit an erection plan for the prefabricated steel bridge superstructure to the c.o. for approval 14 days before erection is scheduled.

If allowed under the project design criteria, temporary in-stream support bents may be used for the erection of the prefabricated steel truss bridge. The in-stream bents shall be cribbing, sills, concrete blocks or other supports and shall be placed with minimal disturbance within the stream. All materials to construct the temporary in-stream bents shall be removed. The submittals shall include drawings indicating temporary bent locations and details also included, the contractor shall indicate the equipment and methods proposed to install and remove the temporary bents and erect the new prefabricated steel truss superstructure.

TIMBER & LUMBER: Solid sawn timber members shall conform to the requirements of the grading rules agency for the species, type, and grade specified below.

DECK PLANKS - COASTAL REGION DOUGLAS FIR-LARCH ROUGH SAWN

No.1 GRADE, GRADING RULES AGENCY - WWPA, WCLIB

RUNNING PLANKS - COASTAL REGION DOUGLAS FIR-LARCH ROUGH SAWN

No.2 GRADE, GRADING RULES AGENCY - WWPA, WCLIB

TREATMENT: See project criteria for members identified to be treated and for treatment type. Preservative treatment shall be in accordance with the current awpa specifications using the treatment materials listed below. Treatment will comply with the requirements of the current edition of WWPI'S "Best Management Practices for the Use of Treated Wood in Aquatic Environments".

SOLID SAWN LUMBER - AWPA C2 (ABOVE GROUND USE)

(TYPE C SOLVENT) - PENTACHLOROPHENOL IN LIGHT OIL

(TYPE A SOLVENT) - COPPER NAPHTHENATE IN HEAVY OIL

FIELD TREATMENT: Copper naphthenate (2% solution) shall be furnished for field treating of wood. All abrasions and field cuts -approved by the C.O.R.- shall be carefully trimmed and given three brush coats of the field treatment solution. Where approved field drilling of bolt or nail holes is required, the holes shall be poured full of preservative prior to inserting the fasteners.

TIMBER FABRICATION: Submit shop drawings for all timber bridge components.

Show all dimensions and fabrication details for all cut or bored timber. Field drilling of holes shall not be allowed unless otherwise noted on the plans.

STORAGE OF FUEL AND OTHER TOXICANTS: Storage within riparian conservation areas (RCA's), defined as areas within 300 feet of live streams, is prohibited. Refueling of equipment may be done within the RCA only at locations approved by the COR. Place pumps used for removing water from structure excavation in a secondary spill container with sufficient capacity to contain the quantity of fuel in the pump fuel tank. Submit a spill prevention & containment plan to the COR for approval prior to beginning construction. A sample plan form is available and can be obtained at the pre-work meeting. Provide a spill containment kit on site that will be able to accommodate potential spills from the equipment used during construction.

PLACED RIPRAP:

Place class 5 riprap as depicted in the drawings and as staked by the engineer.

Thickness is 2 feet, measured perpendicular to the stream bank. Slopes to be ripraped shall be reasonably smoothed and covered with geotextile fabric, Contech C70/06 woven monofilament or equivalent, prior to installation. Estimated quantity of geotextile fabric is 140 square yards; payment for furnishing and installation of geotextile is indirect to item 25101.

SEDIMENT CONTROL:

Install six sediment mats and six 9"x25' straw waddles where staked by the engineer prior to any excavation work at the work site. Use Indian Valley Industries (800-659-5111) 4' x 10' sedimats or equivalent. Leave the sediment control devices in place until removal is approved by the COR. The contractor is responsible for removal of sediment mats and waddles. Remove the sediment mats and waddles from National Forest land. Removal is indirect to pay item 15713

STRUCTURE EXCAVATION:

Protect all stockpiles from material loss by surrounding with straw bales, wattles, or silt fence. Approximately 70 CY of excess material will be generated on either side of the bridge. The excess material shall be incorporated into the cutslope side of the road on either side of the bridge, smooth material as directed by the COR. Leave the finished surface at the approaches to the bridge suitable for driving by a low clearance vehicle. Payment is indirect to pay item 55202.

BEDDING AND BACKFILL:

If excavation can be accomplished without disturbing the subgrade the precast footings may be placed directly on the native subsurface material. However, if overexcavation occurs or if the footings can not be placed to the designed line and grade on native material. The contractor shall place 6 inches of foundation fill material conforming to FSSS 704.01 (1" minus drain rock) under the footings. Wrap foundation fill bottom and sides with geotextile fabric. Payment is indirect to pay item 55202.

SEEDING, FERTILIZING, AND MULCHING:

Seed, mulch, and fertilize all new and disturbed slopes. The estimated area is 0.05 acres.

Use the following weed free seed mix:

Species Pounds Per Acre

Mountain Brome (Bromar) 8 Streambank Wheatgrass (Sodar) 6 Slender Wheatgrass (Pryor or Revenue) 6 Sheep Fescue (Covar) 2 Hairy Vetch 1 Birdsfoot Trefoil 2

Total 25 lb/acre

Use certified weed free straw bales for mulch. Application rate for mulch is 109 bales per acre. Apply Biosol Mix 7-2-3 fertilizer or equivalent with seed and mulch at a rate of 800 lb. per acre. This product is available at:
