CONST.STP-M-5330(10)

SPECIAL NOTES

1. WHEN CONSTRUCTION OPERATIONS AND PHASING REQUIRE THE REMOVAL OR RELOCATION

OF EXISTING SIGNAL EQUIPMENT (I.E., SIGNAL SUPPORTS, BASE-MOUNTED CONTROLLERS),

THE CONTRACTOR MAY USE THE FOLLOWING METHODS TO MAINTAIN SIGNALIZATION.

I. THE CONTRACTOR MAY RELOCATE EXISTING EQUIPMENT.

II. THE CONTRACTOR MAY USE PROPOSED EQUIPMENT. EQUIPMENT SUCH AS SIGNAL

SUPPORTS, BASE-MOUNTED CONTROLLERS, PULL BOXES, AND CONDUIT SHALL BE

INSTALLED IN THE PROPOSED FINAL LOCATION AND AT FINAL GRADES AND SHALL NOT

BE RELOCATED. IF PROPOSED SPAN WIRE AND/OR SIGNAL CABLES ARE USED WITH

TEMPORARY SUPPORTS, SUFFICIENT SLACK SHALL BE LEFT TO ATTACH TO FINAL

SUPPORTS AND FOR FINAL SIGNAL HEAD ALIGNMENT OR FOR REPOSITIONING

EQUIPMENT DURING CONSTRUCTION PHASING. IF CONDITIONS MAKE IT IMPRACTICAL TO

LEAVE SLACK IN SPAN WIRE, THE PROPOSED SPAN WIRE MAY BE OVERRUN, AS

APPROVED BY THE ENGINEER. (IN PROJECTS WHERE FINAL SUPPORTS ARE MAST ARM

POLES AND TEMPORARY WOOD POLES ARE PROVIDED IN THE PLANS, TEMPORARY SPAN

WIRE WILL ALSO BE PROVIDED IN THE PLANS.

III.THE CONTRACTOR MAY SUPPLY AND USE TEMPORARY EQUIPMENT, AS PROVIDED

FOR IN THE PLANS OR AT HIS OWN DISCRETION. THIS MATERIAL AND EQUIPMENT, WHILE

NOT REQUIRED TO BE NEW, SHALL BE IN GOOD CONDITION AND READY FOR USE. IF THE

CONTRACTOR ELECTS TO USE A TRAFFIC SIGNAL CONTROLLER THAT IS NOT NEW,

CERTIFICATION SHALL BE SUBMITTED THAT THE EQUIPMENT HAS BEEN TESTED TO THE

ORIGINAL MANUFACTURER'S SPECIFICATIONS AND IS IN GOOD WORKING CONDITION,

AND THAT ALL APPLICABLE NEMA ENVIRONMENTAL STANDARDS ARE MET. WHEN THE

CONTRACTOR SUPPLIES AND USES TEMPORARY EQUIPMENT, HE ASSUMES ALL

MAINTENANCE RESPONSIBILITIES ASSOCIATED WITH THAT EQUIPMENT, AND RETAINS

POSSESSION OF THE EQUIPMENT AT THE END OF ITS USE.

2. EXISTING TRAFFIC SIGNALS SHALL REMAIN OPERATIONAL UNTIL THE PROPOSED SIGNALS

ARE PLACED IN OPERATION.

3. WHEN IT IS NECESSARY TO PUT AN EXISTING TRAFFIC SIGNAL OUT OF OPERATION FOR

SHORT PERIODS OF TIME, THE CONTRACTOR SHALL NOTIFY CITY OF BROWNSVILLE A

MINIMUM OF TWENTY-FOUR (24) HOURS IN ADVANCE OF CONSTRUCTION OPERATIONS TO

PROVIDE A COMMISSIONED OFFICER WITH POLICE CAR TO CONTROL TRAFFIC. THE SIGNAL

SHALL BE PLACED BACK IN OPERATION BY THE END OF THE WORKING DAY.

4. THE LOCAL AGENCY IS RESPONSIBLE FOR ROUTINE MAINTENANCE OF EXISTING SIGNAL

EQUIPMENT DURING CONSTRUCTION. ANY EXISTING EQUIPMENT THAT IS DAMAGED BY THE

CONTRACTOR'S OPERATIONS SHALL BE REPAIRED OR REPLACED TO THE SATISFACTION OF

THE ENGINEER AT THE CONTRACTOR'S EXPENSE.

5. THE CONTRACTOR SHALL NOTIFY THE LOCAL AGENCY A MINIMUM OF TWENTY-FOUR (24)

HOURS IN ADVANCE OF CONSTRUCTION OPERATIONS THAT WILL RENDER EXISTING

DETECTION LOOPS USELESS. THE LOCAL AGENCY WILL ARRANGE TO DISCONNECT THE

LOOPS AND MAKE APPROPRIATE ADJUSTMENTS TO SIGNAL TIMING PRIOR TO THESE

OPERATIONS.

6. ALL PROPOSED SIGNAL HEADS SHALL BE BAGGED AND COMPLETELY COVERED UNTIL THEY

ARE PUT INTO USE.

7. PROPOSED SIGNALS INSTALLED AT PREVIOUSLY UNSIGNALIZED INTERSECTIONS SHALL BE

FLASHED A MINIMUM OF SEVEN (7) DAYS UP TO A MAXIMUM OF FOURTEEN (14) DAYS,

BEFORE PUT INTO FINAL OPERATION.

8. THE EXISTING SIGNAL PHASING SHALL BE CONTINUED DURING THE CONSTRUCTION PERIOD.

PROPOSED PHASING, IF DIFFERENT, MAY BE IMPLEMENTED WHEN PROPOSED SUPPORTS,

SIGNAL HEADS, CONTROLLER, AND ROADWAY GEOMETRY ARE IN PLACE SUCH THAT

PROPOSED PHASING IS PRACTICAL.

9. SIGNAL HEADS SHALL BE REPOSITIONED FOR CHANGES IN CONSTRUCTION PHASING TO

CONFORM TO REQUIREMENTS OF THE MANUAL ON UNIFORM TRAFFIC CONTROL DEVICES.

THIS MAY REQUIRE ADDITIONAL NEAR SIDE SIGNAL HEADS IF STOPLINE TO SIGNAL HEAD

DISTANCE EXCEEDS 180' (120' IF 8 INCH LENSES ARE USED) OR IS LESS THAN 40'.
