AVAILABLE FOR INSPECTION BY CITY STAFF FOR THE DURATION OF THE

PROJECT.

1.4 ALL PROPERTY CORNERS, POLES, STUBS, AND ANCHORS WILL BE STAKED

BY CITY STAFF PRIOR TO CONSTRUCTION UNLESS OTHERWISE NOTED IN

THE PROJECT DOCUMENTS. THE CONTRACTOR SHALL BE RESPONSIBLE

FOR VERIFYING THAT ALL STAKED STRUCTURE AND GUY LOCATIONS ARE IN

ACCORDANCE WITH THE PROJECT DRAWINGS AND THAT ALL STAKING WILL

DISTANCES SHALL BE ACCOMPLISHED WITH SKIDS. CANT HOOK OR ANY

OTHER SURFACE PENETRATING EQUIPMENT SHALL NOT BE USED.

3.4 ANY STRUCTURE OR PORTION THEREOF MAY BE ASSEMBLED ON THE

GROUND PRIOR TO ERECTION, PROVIDED THAT THE METHOD WILL NOT

PERMANENTLY DEFORM OR DAMAGE THE STRUCTURE, AND THAT ALL

MATERIAL ON THE STRUCTURE WILL BE PROTECTED DURING ERECTION.

3.5 ALL HOLES REQUIRED FOR STRUCTURAL ASSEMBLY WHICH ARE NOT

DRILLED OR CUT BY THE POLE MANUFACTURER PRIOR SHALL BE DRILLED IN

AN APPROVED MANNER. HOLES, GAINS AND CUTS IN WOOD POLES MADE IN

THE FIELD SHALL BE TREATED WITH A CITY-APPROVED WOOD

PRESERVATIVE.

3.6 AFTER SETTING AND ALIGNING POLES, THE BACKFILL SHALL BE

MECHANICALLY TAMPED FOR THE FULL DEPTH OF THE EXCAVATION IN

LAYERS NOT MORE THAN EIGHT INCHES THICK. BACKFILL SHALL CONSIST

OF SUITABLE MATERIAL FROM THE EXCAVATION. IF INSUFFICIENT MATERIAL

IS AVAILABLE, SELECT BORROW SHALL BE USED. DENSITY OF THE

COMPLETED BACKFILL SHALL EQUAL OR EXCEED THAT OF THE
