CONSTRUCTION NOTES:

THE CONTRACTOR SHALL SUBMIT A RIPRAP GRADATION TEST RESULT ACCORDING TO ASTM D5519 PRIOR TO PLACING ROCK.

DOWEL LAMINATED DECK:

TIMBER DECK PANELS ARE MARKED IN THE SHOP FOR USE IN FIELD PLACEMENT OF THE PANELS ON THE CAPS, e.g. A1, B1, C1.

PANEL "A" IS PLACED FIRST IN ITS FINAL POSITION ON THE CAPS. NEXT DRILL THE 11/16" DIA. HOLES THRU PANEL INTO CAP IN EACH END OF PANEL AT THE LOCATION SHOWN AND FASTEN THE 3/4" DIA. DM. HD. DR. SPKS. NEXT PLACE PANEL "C" SO THAT ITS UPPER SPLICE BLOCK IS DIRECTLY OVER THE LOWER SPLICE BLOCK ON PANEL "A" AND DRAW TIGHT TOGETHER. THEN DRILL THE 9/16" DIA. HOLES THRU LOWER SPLICE BLOCK AND DRIVE THE 5/8" DM. HD. DR. SPIKES IN LOCATION SHOWN. THEN DRILL HOLES THRU PANEL INTO CAP AND FASTEN THE 3/4" DM. HD. DR. SPKS. THEREAFTER, SUCCESSIVELY PLACE PANEL "B" IN THE SAME MANNER, ENSURING ALL PANELS ARE DRAWN TIGHT TOGETHER BEFORE ANY FASTENING OCCURS.

STEEL BANDING ON PANELS IS TO BE REMOVED AFTER PANELS HAVE BEEN PLACED IN THEIR FINAL POSITION ON THE CAPS.

UTILITIES HAVE NOT BEEN PREVIOUSLY LOCATED. MEMBERS WILL THUS BE ROUTINELY NOTIFIED. THIS DOES NOT RELIEVE THE CONTRACTOR OF THE RESPONSIBILITY OF NOTIFYING UTILITY OWNERS WHO MAY NOT BE A PART OF THE "GOPHER STATE ONE CALL" ALERT SYSTEM.

IN LIEU OF A GEOTECHNICAL INVESTIGATION, THE FOUNDATIONS WERE DESIGNED WITH A MAXIMUM BEARING PRESSURE OF 1,100 PSF FOR THE SERVICE LIMIT STATE AND 1,700 PSF FOR THE STRENGTH LIMIT STATE, BASED ON GROSS WIDTH OF THE FOOTING. THE CONTRACTOR SHALL VERIFY SOILS PRIOR TO CONSTRUCTION OF ABUTMENTS BY HAND PROBE, HAND DIGGING AND/OR BACKHOE TO A MINIMUM DEPTH OF 4 FEET BELOW THE BOTTOM OF FOOTING. IF ORGANIC, SOFT OR OTHERWISE UNSUITABLE SOILS ARE ENCOUNTERED, HE SHALL CONTACT THE FOREST SERVICE

CONTRACTING OFFICER REPRESENTATIVE FOR FURTHER INSTRUCTION.

WATER LEVEL IS SUBJECT TO CHANGE. THE CONTRACTOR IS RESPONSIBLE FOR DETERMINING THE EXPECTED WATER LEVELS DURING

CONSTRUCTION.

NO MATERIAL SHALL BE ALLOWED TO ERODE INTO THE WATER COURSE, NOR SHALL MATERIAL BE PLACED INTO THE WATER COURSE EXCEPT AS

SHOWN ON THESE PLANS.

ALL EQUIPMENT SHALL BE CLEANED ACCORDING TO THE SPECIFICATIONS PRIOR TO USE ON THIS PROJECT. CONTRACTOR SHALL MAKE EQUIPMENT

AVAILABLE FOR INSPECTION PRIOR TO MOBILIZATION ONTO FS LANDS.

THE CONTRACTOR SHALL STOP WORK IMMEDIATELY AND NOTIFY THE FOREST SERVICE CONTRACTING OFFICER REPRESENTATIVE IF HERITAGE

RESOURCES OR HUMAN REMAINS ARE ENCOUNTERED.

ALL HOLES DRILLED FOR BOLTS ARE TO BE 1/16" LARGER THAN BOLT SIZE.

HOLES DRILLED FOR 3/4" LAG BOLTS ARE TO BE 9/16" IN DIAMETER FOR THE THREADED PORTION OF THE BOLT AND 13/16" FOR THE SHANK.

ANY NUT OR MACHINE BOLT HEAD IN DIRECT CONTACT WITH TIMBER TO HAVE ONE PLATE WASHER BETWEEN NUT & TIMBER, AND BOLT HEAD &

TIMBER.

ANY NUT OR MACHINE BOLT HEAD IN DIRECT CONTACT WITH STEEL TO HAVE ONE CUT WASHER BETWEEN NUT & STEEL, OR BOLT HEAD & STEEL.

SET THREADS ON ALL BOLTS AT NUT WITH A CENTER PUNCH AFTER TIGHTENING.

ABUTMENTS TO BE BACKFILLED WITH CLEAN GRANULAR FILL PER PLAN. TIMBER CRIBBING TO BE FILLED IN WITH RIPRAP, CLASS 0, MACHINE PLACED.

ALL TIMBER CUT OR DRILLED IN THE FIELD SHALL BE TREATED WITH COPPER NAPHTHENATE (MATCH PROVIDED TREATMENT TYPE).

ALTHOUGH ALL PRACTICAL PRE-FRAMING WILL BE DONE PRIOR TO TREATING, SOME CUTTING & DRILLING WILL BE REQUIRED IN THE FIELD.

IF GALVANIZED FASTENERS ARE CUT OR DAMAGED IN THE FIELD, THEY SHALL BE REPLACED OR TOUCHED UP WITH COLD GALVANIZING COMPOUND

AT THE DISCRETION OF THE FOREST SERVICE CONTRACTING OFFICER REPRESENTATIVE.
