FOR CONSTRUCTION OF ROADS AND BRIDGES ON FEDERAL HIGHWAY PROJECTS, FP-14" AND

"FOREST SERVICE SUPPLEMENTAL SPECIFICATIONS (FSSS)".

II. DESIGN LOADING

1. THIS STRUCTURE WAS ANALYZED AND DESIGNED FOR A REINFORCED CONCRETE TRAIL

BRIDGE ABUTMENT WALL AND FOUNDATION WITH A LIVE LOAD SURCHARGE (TRAFFIC).

2. THE HEADWALL WAS CHECKED FOR STRENGTH 1 LIMIT STATE (11.5.3) AND SERVICE I LIMIT

STATE (11.5.2) FOR SLIDING STABILITY, OVERTURNING STABILITY, ECCENTRICITY LIMIT, AND

BEARING RESISTANCE.

III. EXCAVATION AND EXCAVATION SAFETY

1. STRUCTURAL EXCAVATION SHALL BE TO THE ELEVATIONS SHOWN ON THE DRAWINGS.

REGARDLESS OF MATERIAL ENCOUNTERED, UNLESS BEDROCK.

2. THE WALLS FOR THE STRUCTURE EXCAVATION SHALL BE SHORED OR SHIELDED, OR LAID

BACK, IN ACCORDANCE WITH "CONSTRUCTION STANDARDS FOR EXCAVATION", AS REQUIRED

BY OSHA 29 CFR, PART 1926, 650-652.

IV. SITE MAINTENANCE

1. ALL AREAS DISTURBED BY CONSTRUCTION OPERATIONS SHALL BE SHAPED TO FINAL GRADE, AS SHOWN ON THE DRAWINGS, AND/OR AS NEEDED (AS DETERMINED BY THE CONTRACTING

OFFICER). FINAL GRADING AND CLEAN-UP IS REQUIRED BEFORE APPROVAL OF FINAL

INVOICING.

2. SITE DISTURBANCE AND CLEARING SHALL BE LIMITED TO THE AREAS AS SHOWN IN THE

PLANSET DRAWINGS, AND WHERE CONSTRUCTION EQUIPMENT WILL BE STORED OR USED.

ANY TREES TO BE REMOVED AND CLEARED THAT'S NOT SHOWN IN THE PLANSET DRAWINGS

SHALL BE APPROVED BY THE C.O. PRIOR TO THE CONTRACTOR CUTTING OR REMOVING.

3. THE CONTRACTOR SHALL PREVENT ANY EXCAVATED MATERIAL FROM ENTERING INTO THE

CREEK AT ALL TIMES. ALL MATERIAL EXCAVATED SHALL BE PLACED AWAY FROM THE CREEK

A MINIMUM OF 25 FEET FROM THE EDGE OF THE CREEK, AND UTILIZE WEED-FREE CERTIFIED

STRAW WATTLES AROUND PERIMETER OF STOCKPILED MATERIAL.

4. INSPECT ALL EROSION CONTROL DEVICES AT THE START OF WORK, EACH DAY, OR AFTER

RAINFALL EVENTS GREATER THAN 0.5 INCHES. DAMAGED EROSION CONTROL DEVICES SHALL

BE REPAIRED IMMEDIATELY.

5. USE SEED-MIX OR EROSION CONTROL BLANKETS, AS INDICATED IN THE CONTRACT, TO

HAND-BROADCAST OVER THE AREAS OF DISTURBANCE. APPLY WEED-FREE STRAW MULCH

TO THE DISTURBED AREA, AT A RATE OF 4,000 POUNDS PER ACRE AS COVERED IN THE

SCHEDULE OF ITEMS.

6. CONTRACTOR SHALL NOT ALLOW WATER TO POND IN CONSTRUCTION AREA DURING

CONSTRUCTION DURATION.

V. STORAGE, CONSTRUCTION, AND CLEARING NOTES

1. CONSTRUCTION EQUIPMENT SHALL BE STORED A MINIMUM OF 25 FEET AWAY FROM THE EDGE OF THE CREEK, AND ON STABLE GROUND.

CONTRACTOR'S STAGING AND STOCKPILING AREAS SHALL BE APPROVED IN WRITING BY THE C.O.

2. USE CONTAINMENT PADS UNDER EQUIPMENT IF IT WILL BE STORED OVERNIGHT NEAR THE WORK SITE TO REDUCE POTENTIAL CONTAMINATION.

3. CONTRACTOR IS SOLELY RESPONSIBLE FOR REPLACING ANY BOARDWALK COMPONENTS THAT ARE DAMAGED, STOLEN, OR LOST DURING THE

COURSE OF THIS PROJECT. SECURITY AT ALL DESIGNATED AND APPROVED STAGING AREAS SHALL BE THE SOLE RESPONSIBILITY OF THE

CONTRACTOR.

4. CONTRACTOR SHALL PLACE EXCESS EXCAVATION AT AN AREA DESIGNATED BY THE C.O. AND HAUL ALL UNSUITABLE EXCAVATION TO AN APPROVED

LANDFILL OFF GOVT. LANDS.

5. CONTRACTOR SHALL IDENTIFY TREE OR SNAGS TO BE CUT PRIOR TO WORK THAT'S NOT IDENTIFIED IN PLANS. OBTAIN APPROVAL FROM THE C.O.

PRIOR TO CUTTING. CUT AND BULK FELLED TREES IN AN APPROVED AREA AS DESIGNATED BY THE C.O...

6. THE CONTRACTOR SHALL CONFINE ALL OPERATION AND ACTIVITIES TO IDENTIFIED CLEARING LIMITS UNLESS OTHERWISE SHOWN ON DRAWINGS.

7. IN THE EVENT THAT PREVIOUSLY UNDISCOVERED CULTURAL RESOURCES ARE ENCOUNTERED DURING THE COURSE OF THE PROJECT, ALL

GROUND-DISTURBING ACTIVITIES WILL BE HALTED UNTIL EVALUATED BY THE GOVERNMENT. IF NECESSARY, THE PROJECT MAY BE MODIFIED IN

ORDER TO PROTECT RESOURCES BEFORE WORK CONTINUES.

VI. SURVEY CONTROLS

1. ALL SURVEY DATA WAS RECORDED AND OBTAINED BY AEI FIRM.

2. CONTROLS AND BENCHMARKS COORDINATES ARE INCLUDED IN THE PLANSET DRAWINGS. CONTROLS ARE SET USING SPIKE NAILS AND PK NAILS.

3. THE CONTRACTOR SHALL FIELD VERIFY ALL SURVEY CONTROLS PRIOR TO THE START OF CONSTRUCTION.

4. FIELD SURVEY DATA WAS COLLECTED ON MARCH 19TH, 2024.

5. COORDINATE SYSTEM: NAD83 PUERTO RICO AND VIRGIN ISLANDS, US SURVEY FOOT

6. COORDINATE SYSTEM CODE: PR83F

7. DATUM: NAD83

8. ALL DISTANCE AND ELEVATIONS ARE INDICATED IN US SURVEY FEET.

BE SURE ALL SLEEVES, CONDUIT, CHASES, ETC., ARE PROPERLY INSTALLED. THE

CONTRACTOR SHALL NOTIFY THE CO AND/OR COR AS SOON AS PRACTICAL, BUT AT LEAST 72

HOURS PRIOR TO PLACING CONCRETE TO ALLOW INSPECTION OF REINFORCING AND

EMBEDDED ITEMS.

7. THE CONTRACTOR SHALL THOROUGHLY FAMILIARIZE HIMSELF. WITH THE FINDINGS AND

RECOMMENDATIONS OF THE GEOTECHINCAL REPORT AND SHALL PERFORM ALL EARTHWORK

OPERATIONS IN ACCORDANCE WITH THESE RECOMMENDATIONS. .

8. FOOTING CONCRETE SHALL BE PLACED THE SAME DAY. EXCAVATIONS ARE OPENED. IF THIS

IS IMPOSSIBLE, STEPS SHALL BE TAKEN TO ADEQUATELY PROTECT THE OPEN EXCAVATION.

9. MATERIAL SHALL COMPLY WITH REQUIREMENTS OF DESIGNATED SPECIFICATIONS OF

AMERICAN SOCIETY FOR TESTING AND MATERIALS.

10. CONSTRUCTION PROCEDURES SHALL COMPLY WITH RECOMMENDATIONS SET FORTH IN

CONCRETE WORK, CLEAN THE SURFACES OF DUST, FOREIGN MATTER, AND FORM OIL AND

APPLY A CONCRETE STAIN OF THE COLOR PREFERRED BY THE USDA FORESTRY SERVICE,

THE STAIN SHALL BE APPLIED TO ALL EXPOSED SURFACES AND 6 INCHES BELOW GROUND

SURFACE.

15. REINFORCEMENT SHALL BE PLACED AND SECURED PRIOR TO POURING CONCRETE

16. NO CONCRETE SHOULD COME IN CONTACT WITH STREAM FLOW

DEWATERING PLAN:

THE CONTRACTOR SHALL UNDERSTAND THAT ANY EXCAVATION MAY ENCOUNTER WATER. THUS,

FOUNDATIONS MAY NEED TO BE FORMED OR SLEEVED TO PROTECT THE EXCAVATION. THESE

FORMS OR SLEEVES SHALL NOT EXTEND INTO ROCK.

FOOTING CONCRETE SHALL BE PLACED THE SAME DAY EXCAVATIONS ARE OPENED. BEFORE

CONCRETE PLACEMENT FOOTINGS SHALL BE CHECKED FOR WATER INTRUSION, MUD, AND ANY

OTHER DEBRIS. ANY FOUND WILL BE PUMPED OUT AND THE EXCAVATION RECHECKED FOR

CLEANLINESS BEFORE CONCRETE PLACEMENT.

ANY WATER/MATERIAL REMOVED FROM THE EXCAVATION SHALL NOT BE PUMPED INTO THE
