PLAN FOR EACH SCOPE ELEMENT INCLUDING MEANS AND METHODS, WORK SCHEDULE, AND PROPOSED ACCEPTANCE TESTING TO COR FOR

COMMENT AND APPROVAL.

2. ALL TOP AND BOTTOM CHORD GUIDE ROLLERS SHALL BE FIELD ADJUSTED VIA THEIR INDIVIDUAL ADJUSTMENT FLANGES TO BE WITHIN THE

SPECIFIED CLEARANCE TOLERANCES IN THE TABLE BELOW. CLEARANCE TOLERANCES LISTED IN THE TABLE ARE MAXIMUM GAPS ALLOWED

BETWEEN THE ROLLER EDGES AND GUIDES. CLEARANCE TOLERANCES ARE TO BE MEASURED, ADJUSTED AS NEEDED, AND RECORDED AT THE

LISTED LOCATIONS AND SCENARIOS BELOW.

3. SOME GUIDE ROLLERS WILL REQUIRE REMOVING EXISTING COMPONENTS OF THE BRIDGE TO GAIN ACCESS TO THE ADJUSTMENT FLANGES.

PROPER REMOVAL, STORAGE, PROTECTION, RE-INSTALLATION, AND RECALIBRATING (IF REQUIRED) SHALL BE PERFORMED AS PART OF THIS

SCOPE FOR ANY EXISTING COMPONENTS REQUIRED TO REMOVED IN ORDER TO ACCESS ADJUSTMENT FLANGES. SUBMIT AN ASSESSMENT AND

ADJUSTMENT PLAN TO COR FOR APPROVAL PRIOR TO CONDUCTING ANY ADJUSTMENTS. PLAN IS TO CLEARLY EXPLAIN HOW EACH ASSESSMENT

4. GUIDE ROLLER TOLERANCE ASSESSMENTS AND ADJUSTMENTS SHALL BE CONDUCTED BY THE CONTRACTOR AND WITNESSED BY THE

CONTRACTING OFFICER ON TWO SEPARATE DATES AFTER ALL OTHER CONSTRUCTION SCOPE ITEMS HAVE BEEN COMPLETED. THE SELECTED

DATES FOR CONDUCTING ASSESSMENTS AND ADJUSTMENTS SHALL BE APPROVED BY THE CONTRACTING OFFICER PRIOR TO IMPLEMENTATION

AND MUST BE AT MINIMUM 60 DAYS APART AND SHALL TARGET DIFFERENT WEATHER CONDITIONS, SUCH AS AMBIENT TEMPERATURE, HUMIDITY, WIND DIRECTIONS, SUN/CLOUD EXPOSURE.

HOW TO COMPLETE REQUIRED ADJUSTMENTS.

7. AFTER GUIDE ROLLER ASSEMBLY HAS BEEN RE-INSTALLED AND ADJUSTED, CONDUCT ACCEPTANCE TESTING OF THE ADJUSTED GUIDE ROLLERS

TO CONFIRM PROPER OPERATION AND ALIGNMENT. ACCEPTANCE TESTING FOR GUIDE ROLLERS TO CONSIST OF COMPLETING 3 FULL RAISING AND

LOWERING CYCLES OF THE SPAN. DURING TESTING, CONFIRM PROPER NORMAL OPERATION OF GUIDE ROLLERS AND THAT ALL COMPONENTS ARE

IN PROPER ALIGNMENT DURING CYCLES. CONTRACTOR TO CAPTURE LIVE VIDEO OF EACH ROLLER SHOWING PROPER ALIGNED OPERATION WHILE

CONDUCTING ACCEPTANCE TESTING TO BE DELIVERED TO GOVERNMENT FOR REVIEW. CONTRACTING OFFICER'S REPRESENTATIVE IS REQUIRED

TO BE PRESENT FOR THE ACCEPTANCE TESTING. DEVELOP AN ACCEPTANCE TESTING REPORT DOCUMENTING THE SUMMARY OF THE PROCESS

AND RESULTS AND DELIVER TO THE CONTRACTING OFFICER'S REPRESENTATIVE FOR REVIEW AND APPROVAL.
