TRAIL 101, MP 3.1

DESIGN: THIS STRUCTURE HAS BEEN DESIGNED IN ACCORDANCE WITH THE AASHTO "LRFD GUIDE SPECIFICATIONS FOR DESIGN OF PEDESTRIAN BRIDGES", 2009, AND AASHTO LRFD BRIDGE DESIGN

SPECIFICATIONS, 9TH EDITION.

DESIGN NOTES AS FOLLOWS:

DEAD LOAD: ACTUAL

LIVE LOAD: PEDESTRIAN LIVE LOAD = 90 PSF

SNOW LOAD = 150 PSF

ALL OTHER LOADS, COMBINATION OF LOADS, DEFLECTION CRITERIA, ETC. CONFORMS TO THE

GUIDE SPECIFICATIONS FOR DESIGN OF PEDESTRIAN BRIDGES.

GEOTECHNICAL DESIGN PARAMETERS: THE SUBSTRUCTURE IS DESIGNED FOR A NOMINAL

BEARING RESISTANCE OF 6,000 PSF.

TRAIL DESIGN: TRAIL 101 IS CLASSIFIED AS A CLASS 4 TRAIL. TRAIL DESIGN AT BRIDGE

APPROACHES IS DESIGNED ACCORDING TO CORRESPONDING FOREST SERVICE HANDBOOK

REQUIREMENTS.

DESIGN NOTES

GENERAL NOTES

SPECIFICATIONS: CONSTRUCT THE PROJECT IN COMPLIANCE WITH FEDERAL HIGHWAY

ADMINISTRATION STANDARD SPECIFICATIONS FOR CONSTRUCTION OF ROADS AND BRIDGES ON

FEDERAL HIGHWAY PROJECTS (FP-14) AND APPLICABLE SPECIAL PROJECT SPECIFICATIONS.

DISPOSAL: ALL MATERIALS DESIGNATED FOR REMOVAL BECOME THE PROPERTY OF THE

CONTRACTOR AND ARE TO BE DISPOSED OF BY REMOVING FROM SITE IN AN ENVIRONMENTALLY

SAFE MANNER IN ACCORDANCE WITH ALL LOCAL, STATE AND FEDERAL REQUIREMENTS.

IN-STREAM WORK: ALL IN-STREAM WORK WILL BE PERFORMED BETWEEN JULY 15TH AND

SEPTEMBER 1ST.

HELICOPTER STAGING AREA PREPARATION: THE OWNER WILL PREPARE THE HELICOPTER

STAGING AREA ONSITE BY PROVIDING GENERAL FELLING OF HAZARD TREES. IT REMAINS THE

RESPONSIBILITY OF THE CONTRACTOR TO REVIEW THE SITE AND PLAN FOR ANY NECESSARY

IMPROVEMENTS TO FACILITATE PLANNED OPERATIONS.

HELICOPTER TRANSPORT: IT IS ASSUMED THAT HELICOPTER TRANSPORT OF CONSTRUCTION

MATERIALS AND EQUIPMENT WILL BE NECESSARY FOR THE CONSTRUCTION OF THIS PROJECT.

THE STAGING AREAS FOR HELICOPTER TRANSPORTATION ARE ASSUMED TO BE AT THE

TRAILHEAD FOR PICKUP (ROUGHLY THREE MILES FROM THE BRIDGE SITE) AND ONSITE FOR

DROPOFF. THE FINAL STAGING AREAS ARE TO BE COORDINATED WITH THE CO. SUBMIT A PLAN

TO THE CO FOR APPROVAL THAT INCLUDES THE FOLLOWING: HELICOPTER SPECIFICATION AND

LOAD CAPACITY, CONSTRUCTION MATERIALS AND/OR EQUIPMENT THAT WILL BE HAULED, AND A

DETAILED SEQUENCE OF THE TRANSPORTATION OF THE ITEMS.

BRIDGE ERECTION PLAN: SUBMIT AN ERECTION PLAN TO THE CO FOR APPROVAL. PLAN SHALL

INCLUDE A DETAILED DESCRIPTION OF THE STAGING OF THE BRIDGE MATERIALS, A DESCRIPTION

OF ANY PROPOSED TEMPORARY WORKS, THE EQUIPMENT/TOOLS TO BE USED TO SET THE

BRIDGE COMPONENTS IN PLACE, THE SEQUENCING OF THE BRIDGE ERECTION, AND PROTECTIVE

MEASURES FOR EXISTING TREES ADJACENT TO THE BRIDGE. SEE SHEET 9 FOR MORE

INFORMATION.

GOVERNMENT MATERIAL SOURCING: TRAIL EMBANKMENT FILL AND RIPRAP MATERIAL MAY BE

OBTAINED ONSITE UNDER THE DIRECTION OF THE CO. IT IS ASSUMED THAT THESE MATERIALS

CAN BE SOURCED FROM THE HELICOPTER DROPOFF STAGING AREA. MATERIALS MAY NOT BE

OBTAINED FROM THE STREAMBED. AFTER MATERIAL EXTRACTION, RESTORE THE GROUND TO

ITS NATURAL CONDITION ENSURING ADEQUATE DRAINAGE AND PROVIDING PERMANENT

EROSION CONTROL MEASURES.

EVACUATION PLAN: SUBMIT AN EVACUATION PLAN TO THE CO THAT DETAILS CONTRACTOR'S

PLANS FOR THE EVACUATION OF WORKERS IN THE EVENT OF A NATURAL DISASTER OR

EMERGENCY. DETAIL COMMUNICATIONS AND PROTOCOL FOR POSSIBLE EVENTS WHICH INCLUDE

MINOR INJURIES, LIFE THREATENING INJURIES, AND FOREST FIRE.

MATERIAL NOTES

CONCRETE: PROVIDE CONCRETE IN TOP LAYER OF GABION BASKETS ACCORDING TO THE REQUIREMENTS OF FP-14

SECTION 601, MINOR CONCRETE STRUCTURES.

TIMBER & LUMBER: USE SOLID SAWN TIMBER MEMBERS CONFORMING TO THE REQUIREMENTS OF THE GRADING RULES

AGENCY FOR THE SPECIES, TYPE, AND GRADE SPECIFIED BELOW.

TREATMENT: TREAT ALL TIMBER MEMBERS DESIGNATED FOR TREATEMENT AFTER FABRICATION. 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".

FIELD TREATMENT: FURNISH COPPER NAPHTHENATE (2% SOLUTION) FOR FIELD TREATING OF TREATED WOOD. ALL ABRASIONS AND FIELD CUTS (APPROVED BY THE CO) 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.

STRUCTURAL STEEL: PROVIDE STEEL SHAPES CONFORMING TO THE REQUIREMENTS OF AASHTO M270, GRADE 50W (ASTM A709, GRADE 50W). USE BOLTS CONFORMING TO AASHTO M 164 (ASTM F3125 GRADE A325) TYPE 3 WITH TYPE 3 NUTS &

WASHERS.

WHEN STRUCTURAL STEEL IS TO BE WELDED, THE WELDING PROCEDURE SHALL BE IN ACCORDANCE WITH AWS D1.1 AND

SHALL BE SUITABLE FOR THE GRADE OF STEEL AND INTENDED USE OR SERVICE.

STEEL HARDWARE FOR TIMBER STRUCTURES: USE GALVANIZED STEEL SHAPES, PLATES AND BARS CONFORMING TO THE REQUIREMENTS OF AASHTO M183 (ASTM A36). USE GALVANIZED HARDWARE MEETING THE REQUIREMENTS OF AASHTO M270, GRADE 36, WITH GALVANIZED NUTS AND BOLTS CONFORMING TO ASTM A307, GRADE A FOR CONNECTIONS UNLESS OTHERWISE NOTED IN THE PLANS. GALVANIZE ACCORDING TO REQUIREMENTS OF AASHTO M111 (ASTM A123.) USE

PLAN TO THE CO PER SHEET 3.

2) CONTRACTOR IS RESPONSIBLE FOR ANY NECESSARY

IMPROVEMENTS TO THE THE HELICOPTER STAGING AREA TO

FACILITATE PLANNED OPERATIONS.

3) IT IS ASSUMED THAT THE BRIDGE COMPONENTS WILL NOT BE ABLE

TACKLE, SKIDDING, ETC.) FROM THE HELICOPTER STAGING AREA.

4) CONTRACTOR MAY UTILIZE EXISTING BRIDGE AND/OR THE CEDAR

HAZARD TREE DESIGNATED FOR REMOVAL IN ANY TEMPORARY

WORKS THAT ARE DEEMED NECESSARY. MINIMIZE STREAM CHANNEL

DISTURBANCE WHEN CONSTRUCTING TEMPORARY WORKS AND

INCLUDE A DESCRIPTION OF THESE EFFORTS IN THE BRIDGE

ERECTION PLAN.

5) TREES DIRECTLY ADJACENT TO THE BRIDGE THAT ARE NOT

DESIGNATED FOR REMOVAL ARE TO BE PROTECTED AND
