GENERAL NOTES:

SPECIFICATIONS: MATERIALS AND CONSTRUCTION OF THIS STRUCTURE SHALL BE IN ACCORDANCE WITH THE STANDARD SPECIFICATION FOR

CONSTRUCTION OF ROADS AND BRIDGES ON FEDERAL HIGHWAY PROJECTS (FP-14) AND STANDARD SPECIFICATIONS FOR CONSTRUCTION OF

TRAILS AND TRAIL BRIDGES ON FEDERAL PROJECTS.

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 D1.1 & D1.5 AND SHALL BE SUITABLE FOR THE GRADE OF STEEL AND INTENDED USE OR SERVICE.

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 AND BACKING PLANKS

- COASTAL REGION DOUGLAS FIR - LARCH ROUGH SAWN NO.1 GRADE, GRADING RULES AGENCY - WWPA, WCLIB

RUNNING PLANKS AND RUB RAIL

- COASTAL REGION DOUGLAS FIR - LARCH ROUGH SAWN NO.2 GRADE, GRADING RULES AGENCY - WWPA, WCLIB

RAILS, HANDRAILS UNTREATED

- REDWOOD, S4S, NO.2 GRADE GRADING RULES AGENCY - RIS

- WESTERN RED CEDAR, S4S, SELECT STRUCTURAL GRADE GRADING RULES AGENCY - WWPA, WCLIB

RAILS, HANDRAILS TREATED

- HEM - FIR/DOUGLAS FIR, S4S, NO.1 GRADE GRADING RULES AGENCY - WWPA, WCLIB

DESIGN: THE SUPERSTUCTURE AND SUBSTRUCTURE DESIGN SHALL BE PERFORMED BY THE CONTRACTOR TO THE GEOMETRY SHOWN

ON THESE DRAWINGS AND SHALL BE IN ACCORDANCE WITH THE CURRENT EDITION OF THE AASHTO LRFD GUIDE SPECIFICATION FOR

DESIGN OF PEDESTRIAN BRIDGES, CURRENT EDITION OF THE AASHTO LRFD BRIDGE DESIGN SPECIFICATIONS, AND THE DESIGN LOADS

SHOWN ON THESE DRAWINGS. PREFABRICATED STEEL SUPERSTRUCTURE DESIGN SHALL BE A TRUSS CONFIGURATION SIMILAR TO THAT SHOWN

ON THESE DRAWINGS. BRIDGE DESIGN SHALL PROVIDE CAMBER FOR 100% OF THE FULL DEAD LOAD DEFLECTION PLUS 1% OF BRIDGE SPAN. DESIGN

CALCULATIONS AND SHOP DRAWINGS SHALL BE STAMPED BY A LICENSED PROFESSIONAL ENGINEER. THE COMPLETED SHOP DRAWINGS AND

CALCULATIONS SHALL BE SUBMITTED TO THE CONTRACTING OFFICER FOR REVIEW AND APPROVAL PRIOR TO FABRICATION.

ERECTION/REMOVAL PLAN: THE CONTRACTOR SHALL SUBMIT AN ERECTION PLAN FOR THE PREFABRICATED STEEL BRIDGE SUPERSTRUCTURE AND A

REMOVAL PLAN OF THE EXISTING TIMBER/STEEL BRIDGE TO THE C.O. FOR APPROVAL 30 DAYS BEFORE ERECTION IS SCHEDULED.

TREATMENT: PRESERVATIVE TREATMENT SHALL BE IN ACCORDANCE WITH THE CURRENT AMERICAN WOOD PROTECTION

ASSOCIATION (AWPA) SPECIFICATIONS USING THE TREATMENT MATERIALS LISTED BELOW. TREATMENT WILL COMPLY WITH THE

REQUIREMENTS OF THE CURRENT EDITION OF WESTERN WOOD PRESERVERS INSTITUTE (WWPI) "BEST MANAGEMENT PRACTICES

FOR THE USE OF TREATED WOOD IN AQUATIC ENVIRONMENTS". USE ONE OF THE TREATMENT TYPES SHOWN BELOW:

SUBSTRUCTURE, PILING, RETAINING WALLS AND CRIBBING - AWPA UC4C

- COPPER NAPHTHENATE IN HYDROCARBON SOLVENT A

- CCA

- ALTERNATE OIL-BASED PRODUCTS APPROVED BY COR

SUPERSTRUCTURE AND DECKING - AWPA UC4C

- COPPER NAPHTHENATE IN HYDROCARBON SOLVENT A

- ALTERNATE OIL-BASED PRODUCTS APPROVED BY COR

TIMBER WEARING SURFACE

- IF MECHANICAL LIFE < 10 YEARS, TREATMENT IS NOT REQUIRED

- IF MECHANICAL LIFE > 10 YEARS, TREATMENT IS REQUIRED

- IF TREATED - AWPA UC4A, EITHER OIL-BASED OR WATERBORNE TREATMENT OPTIONS AS BELOW.

RAILING POSTS AND RAIL BOARDS - AWPA UC4A

- COPPER NAPHTHENATE IN HYDROCARBON SOLVENT A

- ALTERNATE OIL-BASED PRODUCT APPROVED BY COR

- WATERBORNE TREATMENT SUCH AS ALKALINE COPPER QUAT (FORMULATION A, B, C, OR D), COPPER

AZOLES (FORMULATION B OR C), MICRONIZED COPPER AZOLES (FORMULATION C), OR EQUAL, APPROVED BY COR.

HARDWARE

- HARDWARE THROUGH OR INTO OIL-BASED TREATMENT SHALL BE HOT-DIPPED GALVANIZED PER ASTM A123.

- HARDWARE THROUGH OR INTO WATERBORNE TREATMENT SHALL BE STAINLESS OR HOT-DIPPED GALVANIZED PER

ASTM F593 OR ASTM A123. WOOD SCREWS AND CONSTRUCTION LAGS SHALL MEET ICC AC 257.

ADDITIONAL NOTES

- MATERIALS IN CONTACT WITH MARINE OR BRACKISH WATER SHALL COMPLY WITH CHAPTER 5 OF AWPA BOOK OF

STANDARDS.

- TREATMENT LEVELS SHOWN ABOVE ARE MINIMUM. INCREASED LEVELS ARE ALLOWED, IF APPROVED BY COR.

- USE WATERBORNE TREATMENT (AWPA UC4A) FOR RAILING POSTS AND RAIL BOARDS IN AREAS OF HIGH

PEDESTRIAN USE OR TO REDUCE ODOR.

- INDUSTRIAL ABSORBENT (E.G. ECOSORB OR APPROVED EQUAL) MAY BE APPLIED TO OIL-BASED TREATED

TIMBER TO REDUCE ODOR.

- FIELD TREAT ALL CUTS, BORES, HOLES AND OTHER ALTERATIONS MADE AFTER INITIAL PRESSURE TREATMENT

PROCESS, WITH 3 BRUSH COATS OF COPPER NAPHTHENATE OR ACCORDING TO AWPA M4.

- SEE FPL GENERAL TECHNICAL REPORT NO. 275 FOR AVAILABILITY AND USES OF TREATED TIMBER ALTERNATIVES.
