THE CONTRACTOR CONSTRUCTION SAFETY MANUAL SHALL COMPLY WITH OSHA

29 CFR 1910 AND 29 CFR 1926.

LOCATIONS AND ELEVATIONS OF EXISTING FEATURES TO BE VERIFIED

BY FIELD MEASUREMENTS PRIOR TO CONSTRUCTION OF NEW WORK.

ALL DIMENSIONS ARE TO BE VERIFIED IN THE FIELD. ANY

DISCREPANCIES FOUND BETWEEN THE DRAWINGS AND SPECIFICATIONS

AND SITE CONDITION OR ANY INCONSISTENCIES OR AMBIGUITIES IN

THE DRAWINGS OR SPECIFICATIONS SHALL BE IMMEDIATELY REPORTED

TO THE RESIDENT ENGINEER (RE) IN WRITING, WHO SHALL CORRECT

SUCH INCONSISTENCIES OR AMBIGUITIES IN WRITING. THE CONTRACTOR

SHALL NOT PERFORM ANY WORK BEFORE VERIFICATION AND AFTER

DISCOVERY OF SUCH DISCREPANCIES, INCONSISTENCIES, OR AMBIGUITIES

WITHOUT WRITTEN RE AUTHORIZATION. ANY WORK PERFORMED BY THE

CONTRACTOR AFTER DISCOVERY OF SUCH DISCREPANCIES WITHOUT PRIOR

WRITTEN AUTHORIZATION BY RE WILL BE CONSIDERED TO BE DONE AT THE

CONTRACTOR'S RISK.

FINISHED GRADE SHALL BE SLOPED AT A UNIFORM SLOPE BETWEEN

SPOT ELEVATIONS.

ALL FILL MATERIAL SHALL MEET REQUIREMENTS AS OUTLINED IN THE

PROJECT SPECIFICATIONS.

THE CONTRACTOR SHALL BE RESPONSIBLE FOR ENSURING THAT ALL

SLOPES ARE BUILT IN ACCORDANCE WITH THESE PLANS. IF THERE IS

ANY QUESTION REGARDING THESE PLANS, THE CONTRACTOR SHALL

REQUEST AN INTERPRETATION BEFORE DOING ANY WORK. THE

SILTATION THAT RESULT FROM THEIR OPERATIONS BY APPROPRIATE

MEANS, (SAND BAGS, TEMPORARY DESILTING BASINS, DIKES, ETC.) UNTIL SUCH

TIME THAT THE PROJECT IS COMPLETED AND ACCEPTED BY FAA.

PRIOR TO ANY EXCAVATIONS UNDER THIS CONTRACT, THE

CONTRACTOR SHALL PERFORM GPRS UTILITY LOCATE TO IDENTIFY

ALL UTILITIES AT THE SITE. CONTRACTOR SHALL POTHOLE AND

HAND EXCAVATE NEAR KNOWN UTILITY LINES TO PREVENT EXCAVATION DAMAGE

TO UNDERGROUND UTILITIES.

THE CONTRACTOR SHALL TAKE PRECAUTIONARY MEASURES TO

PROTECT WITHIN THE SITE, ALL UTILITY LINES, EXISTING PERMANENT

STRUCTURES AND ANY OTHER EXISTING LINES THAT ARE NOT OF

RECORD OR SHOWN ON PLANS. ANY UTILITIES OR STRUCTURES

DAMAGED DURING THE COURSE OF CONSTRUCTION SHALL BE

IMMEDIATELY REPAIRED AND/OR REPLACED BY THE CONTRACTOR,

UNLESS APPROVED OTHERWISE BY THE RE, TO A CONDITION EQUAL

TO OR BETTER THAN THE EXISTING AND AS APPROVED BY THE RE.

THE CONTRACTOR SHALL BE RESPONSIBLE FOR RESTORING ANY

DURING THE COURSE OF CONSTRUCTION. THE CONTRACTOR SHALL

PREPARE A PLAN SHOWING PROPOSED LOCATIONS OF STAGING, STORAGE OF

MATERIALS, AND VEHICLES ON SITE TO BE SUBMITTED TO THE RESIDENT

ENGINEER FOR REVIEW, COMMENT AND/OR APPROVAL PRIOR TO START OF

CONSTRUCTION. DUE TO LIMITED SPACE ON SITE, CONTRACTOR SHALL

COORDINATE WITH RE FOR ADDITIONAL AREAS REQUIRED FOR MATERIAL AND

EQUIPMENT STORAGE.

THE NORMAL ACTIVITIES WITHIN THE FACILITY WILL CONTINUE DURING

CONSTRUCTION. CONTRACTOR SHALL DEVISE A DETAILED WORK

SCHEDULE AND CLOSELY COORDINATE WITH THE RE FOR ALL

ACTIVITIES. THE CONTRACTOR SHALL USE GREAT CARE AND

CAUTION WHILE WORKING WITHIN THE EXISTING FACILITY
