SPECIFIED IN THE CONTRACT DRAWINGS AND SPECIFICATIONS.

3. THE GOVERNMENT WILL NOT BE RESPONSIBLE FOR MEANS, METHODS, PROCEDURES, TECHNIQUES, OR SEQUENCES OF CONSTRUCTION THAT ARE NOT SPECIFIED IN THE CONTRACT

DOCUMENTS. THE GOVERNMENT WILL NOT BE RESPONSIBLE FOR FAILURE BY THE CONTRACTOR TO PERFORM WORK ACCORDING TO THE CONTRACT DOCUMENTS.

5. COORDINATES SHOWN ARE IN U.S. FEET AND REFERENCE THE STATE PLANE COORDINATE SYSTEM FOR NEW HAMPSHIRE AND THE NORTH AMERICAN DATUM OF 1983 (NAD 1983).

6. ELEVATIONS SHOWN ARE IN U.S. FEET AND REFERENCE THE NORTH AMERICAN VERTICAL DATUM OF 1988 (NAVD 88). REFER TO TABLE ABOVE FOR BENCHMARK DESCRIPTION AND

CONTROL POINTS COORDINATE LOCATION AND ELEVATION.

7. THE CONTRACTOR IS RESPONSIBLE FOR ALL LAYOUT AND FIELD ENGINEERING REQUIRED FOR COMPLETION OF THIS PROJECT. THE GOVERNMENT WILL NOT PROVIDE SURVEY

SERVICES. SEE SECTION 01 71 23 (FIELD ENGINEERING AND RECORD DRAWINGS).

8. THE CONTRACTOR SHALL VERIFY THAT ACTUAL SITE CONDITIONS ARE CONSISTENT WITH THE EXISTING CONDITIONS DEPICTED ON THE CONTRACT DRAWINGS. DISCREPANCIES, OMISSIONS, AND ERRORS SHALL BE REPORTED TO THE CONTRACTING OFFICER'S REPRESENTATIVE (COR) PRIOR TO THE START OF CONSTRUCTION.

COLD REGIONS RESEARCH AND ENGINEERING LAB (CRREL) DIRECTORATE OF PUBLIC WORKS AND PRIVATE UTILITY LOCATING COMPANIES FOR ADDITIONAL ASSISTANCE WITH

LOCATING UNDERGROUND UTILITIES.

11. WHERE AN EXISTING UTILITY IS FOUND TO CONFLICT WITH THE WORK, THE TYPE, LOCATION, ELEVATION, AND SIZE OF THE UTILITY SHALL BE ACCURATELY DETERMINED WITHOUT

PRESERVED SHALL BE PROTECTED WITH HIGH VISIBILITY FENCING PLACED A MINIMUM 15 FEET FROM THE TREE TRUNK. TREES 6-INCHES OR GREATER AT DBH (DIAMETER BREAST

HEIGHT) SHALL BE PROTECTED WITH FENCING PLACED AT THE CRITICAL ROOT ZONE OR 15 FEET, WHICHEVER IS GREATER.

13. IT IS THE CONTRACTOR'S RESPONSIBILlTY TO PROVIDE AND MAINTAIN EROSION PREVENTION AND SEDIMENTATION CONTROL MEASURES AS FIELD CONDITIONS REQUIRE AND AS

SHOWN ON C-502 AND IN THE SPECIFICATIONS.

14. ALL FILL REQUIRED UNDER THIS CONTRACT SHALL BE OBTAINED AND FURNISHED BY THE CONTRACTOR. ALL FILL REQUIRED BEYOND WHAT IS AVAILABLE FROM ONSITE EXCAVATION

THE TOTAL RESPONSIBILITY OF THE CONTRACTOR.

15. ALL PRECAST CONCRETE PRODUCTS SHALL BE INSPECTED AT THE LOCATION OF MANUFACTURE. APPROVED PRECAST CONCRETE PRODUCTS WILL BE STAMPED OR HAVE SUCH

IDENTIFICATION NOTING THAT INSPECTION HAS BEEN CONDUCTED BY THE PRECASTER. PRECAST CONCRETE PRODUCTS WITHOUT PROOF OF INSPECTION SHALL NOT BE APPROVED

FOR INSTALLATION.

16. THE CONTRACTOR IS RESPONSIBLE FOR OBTAINING ADDITIONAL BENCHMARK INFORMATION IF NEEDED AND FOR LOCATING AND PROTECTING ALL EXISTING BENCHMARKS THAT ARE

INTENDED TO REMAIN IN PLACE FOR THE DURATION OF CONSTRUCTION. AT THE CONTRACTOR'S EXPENSE ALL ADDED OR RELOCATED BENCHMARKS SHALL BE RELOCATED BY A

PROFESSIONAL LAND SURVEYOR (PLS) LICENSED IN THE STATE OF NEW HAMPSHIRE.

17. A SMOOTH TRANSITION SHALL BE PROVIDED BETWEEN EXISTING PAVEMENT AND NEW PAVEMENT. FIELD ADJUSTMENT OF FINAL GRADES MAY BE NECESSARY. ALL EXISTING

PAVEMENT SHALL BE SAW CUT BEFORE REMOVAL TO OBTAIN A UNIFORM EDGE. INSTALL ALL NEW UNDERGROUND UTILITIES PRIOR TO INSTALLATION OF NEW PAVEMENT.

18. THE CONTRACTOR SHALL PROVIDE PROTECTION TO SURROUNDING PAVEMENT, VEGETATION, STRUCTURES, AND UTILITIES THAT ARE IN THE WORK AREA AND ARE TO REMAIN IN

PLACE. CONTRACTOR CAUSED DAMAGES SHALL BE REPAIRED AND RESTORED TO ORIGINAL CONDITIONS OR BETTER AT THE CONTRACTOR'S EXPENSE. DAMAGES TO EXISTING

ASPHALT AND CONCRETE SHALL INCLUDE, BUT ARE NOT LIMITED TO, CHIPPING, CRACKING, INDENTATIONS, AND SCUFFING.

19. ALL SURFACES DISTURBED BY THE CONTRACTOR WHICH ARE OUTSIDE THE CONSTRUCTION LIMITS OF WORK OR SCOPE OF WORK, OR ARE SURFACES DISTURBED WITHOUT PRIOR

AUTHORIZATION BY THE COR, SHALL BE RESTORED AT THE CONTRACTOR'S EXPENSE TO ORIGINAL CONDITIONS OR BETTER.
