DESIGN SPECIFICATIONS: THIS STRUCTURE IS DESIGNED FOR 125 PSF SNOW LOAD OR

65 PSF PEDESTRIAN LIVE LOAD IN ACCORDANCE WITH THE AASHTO GUIDE

SPECIFICATIONS FOR DESIGN OF PEDESTRIAN BRIDGES.

HYDROLOGY AND HYDRAULICS: THIS STRUCTURE IS DESIGNED TO PASS A 100-YEAR

FREQUENCY FLOOD WITH FOUR FEET OF MINIMUM FREEBOARD. THE DESIGN

VOLUMES ARE AS FOLLOWS:

BRIDGE NO. 32-3.1, Q

= 10,000 CFS, Q

= 1,900 CFS

LUMBER: ALL MEMBERS SHALL BE ROUGH SAWN, EXCEPT WHERE NOTED OTHERWISE.

ALL TIMBER AND LUMBER SHALL BE COAST REGION DOUGLAS-FIR OR SOUTHERN PINE

NO. 1 OR BETTER, EXCEPT RUNNING PLANKS (NO. 2), CONFORMING TO CURRENT

WWPA, WCLIB OR SPIB GRADING RULES. INLAND DOUGLAS-FIR LUMBER SHALL NOT BE

USED ON THIS PROJECT.

GLUED-LAMINATES: GLUED-LAMINATED MEMBERS SHALL BE OF COAST REGION

DOUGLAS-FIR CONFORMING TO THE AMERICAN INSTITUTE OF TIMBER CONSTRUCTION

(AITC) 117-04, AASHTO M168, AND ANSI/AITC A190.1 AND SHALL BE MANUFACTURED

FOR WET CONDITION USE AND INDUSTRIAL APPEARANCE.

TREATMENT: INCISE AND TREAT ALL LUMBER AFTER FABRICATION IN ACCORDANCE

WITH AWPA U1 USING PENTACHLOROPHENOL OR COPPER NAPHTHENATE IN HEAVY

OIL (TYPE A SOLVENT). TREAT TO USE CATEGORY UC4B. COMPLY WITH THE

REQUIREMENTS OF THE CURRENT EDITION OF WWPI'S BEST MANAGEMENT

PRACTICES FOR THE USE OF TREATED WOOD IN AQUATIC ENVIRONMENTS.

FIELD TREATMENT: COPPER NAPHTHENATE (2% SOLUTION) SHALL BE FURNISHED FOR

FIELD TREATING OF WOOD. ALL ABRASIONS AND FIELD CUTS APPROVED BY THE C.O.

SHALL BE CAREFULLY TRIMMED AND GIVEN THREE BRUSH COATS OF THE FIELD

TREATMENT SOLUTION. HOLES DRILLED IN THE FIELD SHALL BE POURED FULL OF

PRESERVATIVE PRIOR TO INSERTING FASTENERS. WHEN POSSIBLE, DO NOT FIELD

TREAT OVER LIVE STREAM. DO NOT SPILL PRESERVATIVE IN STREAM.

INSPECTION AND CERTIFICATION: THE FOLLOWING COMPLIANCE CERTIFICATES SHALL

BE FURNISHED UPON DELIVERY:

A. SUPPLIER CERTIFICATION, FROM A WWPA OR WCLIB APPROVED SUPPLIER, THAT

ALL WOOD MATERIALS MEET REQUIREMENTS AS TO SPECIES AND GRADE.

B. CERTIFICATION OF PRESERVATIVE, PENETRATION IN INCHES, AND RETENTION IN

POUNDS PER CUBIC FOOT (ASSAY METHOD) BY EITHER A QUALIFIED TESTING AND

INSPECTION AGENCY OR SUPPLIER CERTIFICATION. SUPPLIER CERTIFICATION

REQUIRES EACH SOLID PIECE TO BE STAMPED OR BRANDED WITH THE ALSC

QUALITY MARK.

C. CERTIFICATION FROM A QUALIFIED INSPECTION AND TESTING AGENCY

INDICATING CONFORMANCE OF ALL GLUED-LAMINATED MEMBERS WITH AITC

117-04.

D. SUPPLIER CERTIFICATION THAT ALL TREATED WOOD MATERIALS WERE TREATED

IN ACCORDANCE WITH AND MEET THE REQUIREMENTS OF WWPI'S "BEST

MANAGEMENT PRACTICES FOR THE USE OF TREATED WOOD IN AQUATIC

ENVIRONMENTS".

GENERAL

1. PLACE TYPE IV-A GEOTEXTILE UNDER GEOCELL ABUTMENT STABILIZATION AND WRAP OVER THE TOP OF THE GEOCELL

AFTER IT IS BACKFILLED WITH GRANULAR BACKFILL PER FSSS 272. TYPE IV-A GEOTEXTILE SHALL BE CONSIDERED

SUBSIDIARY TO THE CONTRACT PAY ITEM 27250 GEOCELL ABUTMENT STABILIZATION.

GABION

1. WELDED WIRE MESH

GALVANIZED STEEL WIRE, CLASS 3, FINISH 5, SOFT, IN ACCORDANCE WITH ASTM A185.

TENSILE STRENGTH TO BE ACCORDANCE WITH ASTM A641 (SOFT).

ZINC COATING IN ACCORDANCE WITH ASTM A641 (CLASS 3, SOFT), TESTED IN ACCORDANCE WITH ASTM A90.

A. WIRE FOR MESH - 9 GAUGE.

TIE WIRE - 13.5 GAUGE.

MESH OPENING - NOMINAL 3"x3"

2. TOLERANCES

WIRE - TOLERANCES ON THE DIAMETER OF ALL WIRE IN THE ABOVE CLASSES SHALL BE PERMITTED IN ACCORDANCE

WITH ASTM A641.

GABIONS - TOLERANCES OF ±5% ON THE WIDTH AND LENGTH, AND ±10% ON THE HEIGHT.

3. FABRICATION

BASKETS SHALL BE FABRICATED SO THAT THE SIDES, ENDS, LIDS, AND DIAPHRAGMS CAN BE ASSEMBLED AT THE

CONSTRUCTION SITE INTO RECTANGULAR BASKETS OF THE REQUIRED SIZE. WHERE THE LENGTH OF THE BASKET

EXCEEDS 3'-0", IT SHALL BE EQUALLY DIVIDED BY DIAPHRAGMS, MADE OF THE SAME TYPE MESH AS THE BODY, INTO

CELLS NOT EXCEEDING 3'-0" LENGTH. THE DIAPHRAGMS SHALL BE SECURED IN POSITION ON THE BASE SO NO ADDITIONAL

TYING IS NECESSARY AT THIS JUNCTURE.

4. ROCKFILL

GABION FILL SHALL BE A HARD DURABLE AND NON FROST SUSCEPTIBLE ROCK OR STONE TYPE FROM 4" - 8" IN SIZE OR AS

RECOMMENDED BY SUPPLIER. A FIVE PERCENT TOLERANCE ON THE UPPER AND LOWER LIMIT OF STONE GRADATION IS

PERMITTED.

5. CONSTRUCTION

ALL ROCK FILL SHALL BE PACKED TIGHTLY TO MINIMIZE VOIDS AND THE ROCK FILL ON THE EXPOSED FACE OF THE GABION

IS TO BE HAND PACKED. THE ADJACENT GABION UNITS ARE TO BE TIED TOGETHER WITH CONTINUOUS LACING ON THE

VERTICAL JOINTS AS WELL AS HORIZONTALLY AT THE FRONT AND REAR OF COURSED JOINTS. THE UNITS SHALL BE FILLED

SUCH THAT THE MESH LID BEARS ONTO THE ROCK FILL. THE LID SHALL BE WIRED DOWN ON ALL JOINTS AND ACROSS

DIAPHRAGMS. JOINTS SHALL BE CONSTRUCTED USING ALTERNATING SINGLE AND DOUBLE HALF HITCHES (LOCKED

LOOPS) IN EVERY MESH OPENING ALONG THE JOINT.

ALL GABIONS SHALL BE PLACED ON UNDISTURBED SOIL.

ERECTION NOTES:

1. THE DETAILS SHOWN ON THIS SHEET ARE INTENDED ONLY TO DEMONSTRATE POTENTIAL METHODS OF ERECTING THE BRIDGE

SUPERSTRUCTURE. UTILIZING A HELICOPTER TO FLY EACH TRUSS IN (3) PIECES AND ERECT ON EXISTING STRUCTURE IS ASSUMED, HOWEVER ALTERNATE METHODS MAY BE PROPOSED.

2. PROVIDE TIMBER BLOCKING AND SHIMS AT EXISTING PIERS, TEMPORARY BRACE POINTS OR ALONG BEAM AT CONTRACTORS

DISCRETION TO SUPPORT TRUSS ERECTION.

3. TEMPORARY VERTICAL SUPPORTS, CONNECTIONS, LATERAL STABILITY AND LOCATIONS ARE THE RESPONSIBILITY OF THE

CONTRACTOR.

4. PRIOR TO MOBILIZATION TO THE SITE THE CONTRACTOR MUST SUBMIT AN ERECTION PROCEDURE AND ANY PROPOSED TEMPORARY

SUPPORT SYSTEM TO THE CO FOR APPROVAL. INCLUDE CALCULATIONS IN SUFFICIENT DETAIL TO SUBSTANTIATE THAT THE SYSTEM IS

STRUCTURALLY ADEQUATE AND WILL PRODUCE THE REQUIRED FINAL GEOMETRY OF THE SUPERSTRUCTURE. CALCULATIONS AND

FALSEWORK DRAWINGS MUST BE SIGNED AND SEALED BY A PROFESSIONAL ENGINEER LICENSED IN THE STATE OF MONTANA.

5. DO NOT START CONSTRUCTION OF ANY TEMPORARY WORK UNTIL THE CO HAS ACCEPTED THE ERECTION PLAN.

6. THE CONTRACTOR WILL BE ALLOWED TO PLACE TEMPORARY FALSEWORK IN THE STREAM. TEMPORARY WORKS MUST NOT IMPEDE THE

FLOW OF THE STREAM, CREATE UNDO SEDIMENTATION, AND MUST BE ADEQUATELY DESIGNED AND BRACED TO RESIST ANTICIPATED

STREAM FLOWS. FALSEWORK CAN NOT BE PLACED IN THE LIVE STREAM PRIOR TO JULY 15TH AND MUST BE REMOVED BY SEPTEMBER

1ST.

7. ALL SHORING ELEMENTS MUST BE COMPLETELY REMOVED FROM THE STREAM AND UNDER THE STRUCTURE AFTER THE

SUPERSTRUCTURE IS COMPLETE, INCLUDING TEMPORARY FOOTINGS.

8. CONTRACTOR SHALL BRACE ENDS OF TRUSS AND TRUSS SEGMENT ENDS DURING ERECTION AT ALL TIMES UNTIL ENTIRE STRUCTURE

HAS BEEN ASSEMBLED.

9. JACKING, BRACING, SHIMS, TEMPORARY ANCHORAGE ETC. NOT SHOWN AND ARE THE RESPONSIBILITY OF THE CONTRACTOR.

10. EXISTING STRUCTURE HAS LIMITED CAPACITY DUE TO ADVANCED ROT AND DECAY. CONTRACTOR TO VERIFY EXISTING STRUCTURE

CONDITION IF UTILIZING AS PART OF THE TEMPORARY SUPPORT SYSTEM.
