Modifications in the design are to be made only by a qualified professional bridge engineer licensed in the state of Alaska. Modifications to the bridge superstructure only may be made by a qualified professional bridge engineer licensed in the state the company normally conducts business.

c. Design, fabrication and construction of structurally sound abutments and approaches for the trail bridges. Approaches to Upper Granite Creek and Lower Granite Creek bridges will be timber ramps or crushed aggregate that can pass flood waters.

Approaches to all other bridges will be crushed aggregate. Bridge approach construction limits will be from the end of the bridge deck to where the approach meets existing grade. Approach and abutment design are to be performed by a qualified professional engineer licensed in the state of Alaska.

d. Incidental to this work will be the site layout, site preparation, excavation, removal of existing structure at Winner Creek, embankment, compaction, disposal, grading, and all associated items needed to provide a complete and finished product suitable for the intended use.

e. The Spokane, Bertha, Lower Granite, Upper Granite and Lyon Creek bridges are for a snow machine trail. Construction of new trail between the bridges is not included in this contract. The Winner Creek bridge will service the existing Winner Creek Trail.

2. The intent of the contract is to provide for the complete design and construction of the project described in the contract. Unless otherwise provided, the contractor is to furnish all labor, materials, equipment, tools, transportation, and supplies and perform all work required to complete the project in reasonably close conformity with the drawings and specifications, and in accordance with the provisions of the contract. Payment for contract work will be made only for and under those pay items included in the Schedule of Items. All other work and materials will be considered as incidental to and included in the payment for items shown.

3. In addition to the preparation and submittal of stamped and signed abutment design drawings, timber approach ramp design drawings (if this alternate option is awarded), and design calculations, the work also involves the creation of stamped and signed fabrication drawings that will be submitted and used to complete the fabrication and field assembly of the component parts of the bridges. Incidental to this work will be all associated items needed to provide a safe, complete and finished product suitable for the intended use. These items may include, but will not be limited to, fasteners, snow pole sleeves, and other hardware, temporary bracing elements and special erection instructions necessary to facilitate the safe installation of the bridge components.

4. It is the intent of the USDA Forest Service to install the new bridges without skew to the crossing.

937.05 General. Perform the work under Sections 911 and 912. Furnish structural lumber and timber of the required stress grade.

Clear stacks of weeds, rubbish, or other objectionable material from the ground under and in the vicinity of all stored material. Place the bottom layer of material at least 8 inches above the ground level. Provide sufficient support to prevent sagging.

Open-stack untreated material to shed water. Stack material in layers on spacers (stickers) that extend across the full width of the stack to allow for free air circulation. Align all stickers vertically and space them at regular intervals.

Close-stack treated material to shed water.

Protect material from the weather. If covered, use sheet material such as water-resistant paper or opaque polyethylene film. Do not cover with impervious membranes, such as polyethylene film, during dry weather. Slit individual wrappings full length or puncture on the lower side to permit drainage of water.

Store and protect glued laminated timber in accordance with the recommendations for Loading and Handling, Job Site Storage, and Erection in "Recommended Practice for Protection of Structural Glued Laminated Timber During Transit, Storage, and Erection," published by the American Institute of Timber Construction, AITC 111.

Use slings or other devices to protect corners of heavy construction timbers and banded packages of heavy construction timber

937.06 Install bridges at the locations SHOWN ON THE DRAWINGS and STAKED IN THE FIELD BY THE CO. Final locations shall be APPROVED BY THE CO.

937.07 Treated Timber. Fabricate timbers before treatment. Handle treated timber according to the Consumer Information Sheet published by AWPA. Do not cut, frame, or bore treated timber after treatment unless approved by the CO. Handle treated timbers carefully and do not drop, damage outer fibers, or penetrate the surface with tools. Do not use cant dogs, hooks or pike poles. In coastal waters, do not cut or bore timber below the high water mark.

937.08 Workmanship. All carpentry work shall be straight, plumb, level, true, and square, and closely fitted, butted, mitered, or housed as required for neat finished appearance. Cut to eliminate defects. Visible wood shall be free from hammer marks, cracks, and other flaws. Carefully trim all field cuts and abrasions made in fabricated lumber and posts. Limit field cuts to holes and minor trimming and cuts SHOWN ON THE DRAWINGS. Cut and form all lumber and construction timbers so all joints will have even bearing over the entire contact surface. Do not use shims in makings joints.

Construct all joints to be closed.

937.09 Nailing. Where not specified, nails shall be of the type and size as those normally used for the application.

• Securely nail to studs, nailing blocks, furring strips, etc. Place fasteners to draw up parts tight and prevent warping, curling, splitting, or opening of joints from shrinkage.

• Drive nails not closer together than one-half their length nor closer to the edge of the lumber than one-fourth their length. Predrill holes for nails where necessary to prevent splitting.

Predrill holes 75% of nail diameter. Provide nails of such length that when joining two members the penetration of the nail into the second member is greater than one-half the length of the nail. Nailing shall conform to the minimum International Building Code (IBC) (latest edition) requirements. Drive nails and spikes to set the heads flush with the wood surface. Use the same end, face, and edge of the timber member for all layout dimensions. Bore all holes from mating faces.

937.10 Holes for Bolts, Dowels, Rods & Lag Screws. Bore all holes before preservative treating the wood. Bore holes for round drift bolts and dowels to the same diameter as the bolt or dowel to be used. Ensure that the diameter of holes for square drift bolts or dowels is equal to the side dimension of the bolt or dowel.

Bore holes for machine bolts with a bit 1/16 inch larger than the diameter, except when galvanized bolts are specified. In this case, drill all holes 1/8 inch greater than the bolt size. Drill the depth of lag screw holes one inch less than the length of the screw head and with a diameter approximately 75 percent of the shank diameter.

937.11 Hardware. Furnish the hardware as SHOWN ON THE DRAWINGS and indicated in the contractor’s approved plans, as specified below.

(a) Bolts & Washers. Firmly tighten all nuts to provide proper bearing, and cut off excess bolt lengths of more than one inch. After final tightening, check or burr all bolts effectively with a pointing tool to prevent loosening of the nuts.

Use malleable iron washers with a diameter approximately four times the bolt diameter under all bolt heads or nuts in contact with wood, unless otherwise

SHOWN ON THE DRAWINGS.

For bolts of a size for which malleable iron washers are not available, use the largest cut washer of the appropriate size. Malleable iron washers are not required under carriage bolts or steel/timber contact surfaces. Place head of carriage bolts to the interior (pedestrian) side of handrails.

(b) Galvanizing. Unless otherwise SHOWN ON THE DRAWINGS, ensure that all hardware for timber structures is galvanized, except for the glued laminated deck panel dowels. Ensure that all fasteners, including nails, spikes, bolts, washers, and timber connectors, other than malleable iron, are galvanized.

937.12 Foundation. Clean rock or other hard foundation material, cut to a firm surface that is level, stepped, or serrated. Remove all loose and disintegrated rock. Place leveling course of compacted crushed aggregate. Remove unsuitable foundation material and replace with compacted crushed aggregate. Obtain approval of the CO prior to placing leveling course. Mud sills shall be firmly and evenly bedded to solid bearing and carefully tamped in place. Posts for approach ramp shall be buried with compacted base and crushed aggregate fill compacted in six inch layers.

937.13 Decking.
