CONSTRUCTION NOTES:
TRENCH EXCAVATION
THE EXCAVATION OF TRENCHES FOR PIPING LAID IN THE GROUND SHALL BE IN
OPEN—CUT FROM THE SURFACE OF THE GROUND EXCEPT WHERE BORING IS REQUIRED.
THE TRENCHES SHALL BE OF WIDTH AS SHOWN ON STANDARD S-39 AND DETAILED
SECTIONS ON THE PLANS FOR PROPER PIPE INSTALLATION.
CONTRACTOR SHALL PROVIDE TRENCHING IN ACCORDANCE WITH THE DETAILED SECTIONS
PROVIDED IN THE PLANS. SELECTION OF TRENCH TYPES WILL BE AS REQUIRED BY THE
TYPES OF PIPE SELECTED FOR CONSTRUCTION. UTILITY CONDUIT
INSTALLATIONS SHALL MEET CITY STANDARD S-39.
TRENCH LINES SHALL MEET ALL FEDERAL AND STATE SAFETY REQUIREMENTS.
BRACING AND SHORING
EXCAVATION SHALL BE SUPPORTED AS SET FORTH IN THE RULES, ORDERS, AND
REGULATIONS OF THE STATE DIVISION OF INDUSTRIAL SAFETY. IF THE CONTRACTOR
DESIRES TO DEVIATE FROM THE SAFETY ORDERS, HE SHALL SUBMIT DATA BY A
REGISTERED CIVIL ENGINEER TO THE STATE DIVISION OF INDUSTRIAL SAFETY, JUSTIFYING
THE ALTERNATE PROCEDURES TO BE USED. FAILURE TO COMPLY WITH ANY OF THESE
RULES, ORDERS AND REGULATIONS SHALL BE SUFFICIENT CAUSE FOR THE STATE DIVISION
TO IMMEDIATELY SUSPEND ALL WORK. COMPENSATION FOR LOSSES INCURRED BY THE
CONTRACTOR BY SUCH AN EMERGENCY SUSPENSION SHALL NOT BE ALLOWED. DURING
BACKFILLING, THE BOTTOM OF THE SHORING SHALL BE KEPT ABOVE THE LEVEL OF THE
BACKFILL AT ALL TIMES.
SECTION 6422 OF THE CALIFORNIA LABOR CODE REQUIRES THE CONTRACTOR TO SUBMIT
TO THE ENGINEER A DETAILED PLAN, DRAWING THE DESIGN OF SHORING, BRACING,
SLOPING OR OTHER PROVISIONS TO BE MADE BY THE CONTRACTOR FOR THE PURPOSE
OF WORKER PROTECTION FROM THE HAZARD OF CAVING GROUND DURING THE
EXCAVATION OF TRENCHES NECESSARY FOR THE CONSTRUCTION OF THE PROJECT. IF
SUCH PLAN VARIES FROM THE SHORING SYSTEM STANDARD ESTABLISHED BY THE
CONSTRUCTION SAFETY ORDERS, THE PLANS SHALL BE PREPARED AND CERTIFIED BY A
REGISTERED CIVIL OR STRUCTURAL ENGINEER; HOWEVER, USE OF SYSTEMS THAT ARE
LESS EFFECTIVE THAN THOSE REQUIRED BY THE CONSTRUCTION SAFETY ORDERS IS
PROHIBITED ON THIS PROJECT.

PIPE TO SUCH A DEPTH THAT, AFTER THOROUGH CONSOLIDATION, THE FINAL DEPTH
SHALL BE AT LEAST TO THE ELEVATION SHOWN ON THE PLANS. THE MATERIAL SHALL
BE CONSOLIDATED BY VIBRATORY OR MECHANICAL TAMPING AND THE EQUIPMENT AND
MANNER OF TAMPING MUST BE APPROVED IN WRITING BY THE ENGINEER PRIOR TO
COMMENCING OPERATION. IMPACT EQUIPMENT MAY BE ALLOWED UNDER THE DIRECTION

MATERIAL SHALL BE PLACED IN LAYERS NOT EXCEEDING EIGHTEEN (18) INCHES IN LOOSE
DEPTH, EACH LAYER BEING THOROUGHLY COMPACTED BY TAMPING AND/OR ROLLING
BEFORE SUCCEEDING LAYERS ARE PLACED.
COMPACTION OF SUBSEQUENT BACKFILL WITHIN TWO AND ONE—HALF (2-1/2) FEET OF
FINISHED PERMANENT SURFACING GRADE SHALL BE ACCOMPLISHED BY TAMPING AND/OR
ROLLING AS SPECIFIED ABOVE. WHERE THE TRENCH IS WITHIN THE PAVEMENT ON
STREETS, THE BACKFILL WITHIN TWO AND ONE—HALF (2-1/2) FEET OF FINISHED
PERMANENT GRADE SHALL BE COMPACTED TO NINETY PERCENT (90%) RELATIVE
COMPACTION.
