1. INTEGRAL MESSENGER TYPE INTERCONNECT CABLE MEETING
THE REQUIREMENTS OF C&MS 732.19. UNDER THIS METHOD
ANY SECTIONS OF CABLE SHOWN IN THE PLANS TO BE
CONTAINED IN CONTROLLERS, CABINETS, POLES, CONDUITS
OR SUPPORTED ON MESSENGER WIRE INSTALLED FOR OTHER
PURPOSES SHALL HAVE THE SUPPORTING MESSENGER AND
JACKET WEB NEATLY REMOVED BY THE USE OF A TOOL
SPECIFICALLY DESIGNED AND SIZED FOR THIS PURPOSE.
DEVIATIONS FROM THE CABLE ROUTING SHOWN IN THE PLAN,
FOR THE SOLE PURPOSE OF REDUCING THE AMOUNT OF
MESSENGER TO BE REMOVED, WILL NOT BE PERMITTED. THE
CABLE SHALL BE INSTALLED WITH APPROXIMATELY ONE TWIST
FOR EACH 15 FEET OF SPAN LENGTH.
2. SEPARATE INTERCONNECT CABLE MEETING THE REQUIRE-
MENTS OF C&MS 732.19 PLUS A 1/4 INCH MESSENGER WIRE

UNDER THIS METHOD THE CONTRACTOR WILL INSTALL A
SEPARATE 1/4 INCH MESSENGER TO SUPPORT THE SPANS OF
INTERCONNECT CABLES IN ALL LOCATIONS WHERE THE PLANS
SHOW INTERCONNECT CABLE WHICH IS NOT OTHERWISE
SUPPORTED BY A SIGNAL MESSENGER WIRE OR OTHER
SUITABLE SUPPORT. UTILIZATION OF EXISTING MESSENGER
WIRE, NOT PROVIDED BY THE PROJECT OR DESIGNATED
THEREIN AS AVAILABLE FOR USE, IS PROHIBITED. DEVIATION
FROM THE CABLE ROUTING SHOWN IN THE PLANS, FOR THE
PURPOSE OF REDUCING THE NEED FOR SEPARATE
MESSENGER WIRE, WILL NOT BE PERMITTED.
IN EITHER CASE THE NUMBER OF SPLICE LOCATIONS SHALL BE
KEPT TO A MINIMUM.
MEASUREMENT WILL BE BASED UPON THE NUMBER OF FEET OF
C&MS ITEM 632, "INTERCONNECT CABLE, MISC.: (BY SIZE), WITH
SUPPORT MESSENGER, AS PER PLAN" IN PLACE IN ACCORDANCE
WITH THE METHOD DESCRIBED IN C&MS 632.29 AND NO SEPARATE
PAYMENT WILL BE PROVIDED FOR ANY SEPARATE MESSENGER
WIRE USED TO SUPPORT INTERCONNECT CABLES.~~

installed in an existing cabinet.~~
442-7
DETECTION MAINTENANCE^^
IF VEHICLE DETECTION BECOMES UNEXPECTEDLY DISABLED,
REQUIRES MODIFICATION, OR IS SCHEDULED TO BE
TEMPORARILY REMOVED DURING THE CONSTRUCTION PROJECT,
THE CONTRACTOR SHALL IMMEDIATELY NOTIFY THE PROJECT
ENGINEER AND DISTRICT TRAFFIC ENGINEER.
IF THE LOSS OF VEHICLE DETECTION IS KNOWN PRIOR TO THE
START OF CONSTRUCTION, IT SHALL BE DISCUSSED AT THE
PRECONSTRUCTION MEETING. AT SUCH TIME, THE DISTRICT
TRAFFIC ENGINEER SHALL ADVISE THE PROJECT ENGINEER AND
CONTRACTOR ON THE APPROPRIATE ACTION TO RECTIFY ANY
LOSS OF VEHICLE DETECTION. THIS MAY INCLUDE PLACING
THE TRAFFIC SIGNAL ON MINIMUM OR MAXIMUM RECALL, MODIFYING
THE MINIMUM GREEN TIMES, AND REMOVING THE MALFUNCTIONING
DETECTION FROM SERVICE. WHERE NON-INTRUSIVE DETECTION
(I.E. VIDEO, RADAR) ALREADY EXISTS, THE CONTRACTOR SHALL
INSURE THAT DETECTION IS OPERATING AND MAINTAINED BY
RECONFIGURING THE DETECTION UNITS ACCORDINGLY DURING ALL
CONSTRUCTION PHASES. THIS IS TO AVOID THE SIGNAL FROM
MAXING OUT THE EFFECTED SIGNAL PHASE AND CREATING
UNNECESSARY DELAYS.
LOCATIONS WHERE NON-INTRUSIVE DETECTION IS PROPOSED
AND THE EXISTING VEHICLE DETECTION IS TO BE ABANDON,
THE NON-INTRUSIVE VEHICLE DETECTION SHALL BE INSTALLED,
CONFIGURED AND MADE FULLY FUNCTIONAL PRIOR TO THE
EXISTING DETECTION BEING DISABLED. THE CONTRACTOR SHALL
CONTINUE TO MAINTAIN AND MODIFY THE DETECTION UNTIL
FINAL ACCEPTANCE OF THE TRAFFIC SIGNAL. THIS IS TO

ENCLOSURES SHALL BE FREE OF SHARP EDGES AND BE
COVERED BY INSULATED BUSHINGS. FOLLOWING INSTALLATION,
THE GROUND SURFACE SHALL BE RESTORED TO THE ORIGINAL
CONTOUR AND SURFACE CONDITION.~~
Designer Note:
This method may be considered in lieu of cable in conduit to reduce project costs.
It is applicable to long underground runs in tree lawns or grassed roadsides where
minimal interference with driveways or utilities is expected, and where disturbance
of the area due to construction is not contemplated. If the cable is to be routed
up a pole, a conduit riser (extending below ground with an insulated bushing)
should be called for and detailed.~~

confirmation of UPS status if desired. Maintaining agencies may change or omit the recommended
display, if desired, on either new or existing cabinets. The specified domed lens has better
visibility than a flat lens, but is slightly more vulnerable to vandalism. A flat indicator
lamp may be specified instead, if visibility is good and/or vandalism is a concern. If vandalism
is a specific concern, external indicator lamps should not be used. The lamp may be placed on
the cabinet roof instead of the wall, if desired. The operating voltage may be changed if required.~~

OPERATION, THE CONTRACTOR WILL BE COMPENSATED FOR
EACH PARTIAL FOUNDATION EXCAVATION ACCORDING TO THE
BID PRICE.
BEFORE THE CONTRACTOR BEGINS THE EXCAVATION AT THE
MODIFIED LOCATION, THE CONTRACTOR SHALL VERIFY THAT
THERE WILL BE NO OVERHEAD UTILITY CONFLICTS RESULTING
FROM THE NEW SIGNAL SUPPORT LOCATION. NEW SUPPORT
LOCATIONS ARE TO BE APPROVED BY THE ENGINEER.
THE WORK WILL INCLUDE BACKFILLING, COMPACTING, AND

Designer Note:
Use this specification in place of Item 632 Pedestal Foundation only when necessary,
such as for knockdown replacement and similar situations that require a quick
installation. The concrete 632 Pedestal Foundation item is standard for new design,
but the Auger-In Foundation is suitable for maintenance installations. The minimum
specified length is five feet (60 inches) in urban areas and 6 feet (72 inches) in
rural areas. For maintenance purposes, these two sizes are generic. Generally, the
designer also specifies a breakaway Transformer Base as part of the complete assembly.
The designer shall perform basic 90mph design wind speed overturning moment calculations
for all sign, signal, or light pole assemblies mounted on auger-in bases using
the AASHTO LRFDLTS-1, with parameters per TC-81.22. Use this design overturning moment and
local soils data to determine the required foundation dimensions using the Drilled Shaft
Foundation Design Spreadsheet provided by the Office of Roadway Engineering (ORE); the
spreadsheet is available for download from the ORE website.
District approval is required before using this item in construction plans; provide
copies of the spreadsheet and soils data to the District.~~

ENGINEER SHALL PROVIDE GUIDANCE AS TO THE RELOCATION
OF THE SUPPORTS.
DUE TO THE FURTHER POSSIBILITY OF CONFLICT WITH EXISTING OR PROPOSED
UNDERGROUND OBSTRUCTIONS (INCLUDING THE POSSIBILITY OF UNRECORDED OBSTRUCTIONS)
WHICH COULD AFFECT THE LOCATION OF THE FOUNDATION FOR THIS ITEM, AND CONSEQUENTLY,
THE DESIGN OF THE SUPPORT AND/OR ARMS, THE CONTRACTOR SHALL NOT PLACE FINAL
ORDERS FOR THE ITEM UNTIL THE FOUNDATIONS HAVE BEEN INSTALLED, AT FINAL GRADE,
AND THE CONTRACTOR HAS RECEIVED, FROM ENGINEER, WRITTEN NOTICE TO PROCEED WITH
THE ORDERS FOR THE ITEM.
IF ANY FOUNDATION LOCATIONS MUST BE ADJUSTED, THE CONTRACTOR SHALL NOTIFY
THE ENGINEER AND MAINTAINING AGENCY, WHO WILL DETERMINE THE REVISED LOCATION
AND IF NEEDED, THE SUPPORT DESIGN. THE CONTRACTOR WILL NOT BE RESPONSIBLE
FOR DETERMINING THE REVISED DESIGN. THE ENGINEER WILL INFORM THE CONTRACTOR
OF ANY CHANGES NECESSARY AND AUTHORIZE THE CONTRACTOR TO ORDER THE SUPPORT.
THE CONTRACTOR SHALL, WHEN DEVELOPING THE PROGRESS SCHEDULE,
AND THOSE OF SUBCONTRACTORS, ENSURE THAT THE FOUNDATIONS
ARE INSTALLED AT THE EARLIEST TIME AS IS FEASIBLE AND PRACTICAL, AND SHALL
INCLUDE SUFFICIENT TIME IN THE PROGRESS SCHEDULE FOR ORDERING, MANUFACTURING,
DELIVERY, AND INSTALLATION OF THE SUPPORT ITEMS AFTER THE FOUNDATIONS ARE IN PLACE.
NO PAYMENTS FOR DELIVERED MATERIALS FOR THE FOUNDATION OR SUPPORT ITEMS SHALL BE
MADE UNTIL THE FOUNDATIONS ARE IN PLACE, AND IF CHANGES IN THE DESIGN OF
THIS ITEM ARE REQUIRED, NO PAYMENT SHALL BE MADE FOR THE ITEMS MANUFACTURED
TO THE ORIGINAL DESIGN.
PAYMENT WILL BE AT THE CONTRACT UNIT PRICE AND WILL BE
FULL COMPENSATION FOR ALL LABOR, MATERIALS, TOOLS,
EQUIPMENT AND OTHER INCIDENTALS NECESSARY FOR EACH
SUPPORT FURNISHED, IN PLACE, COMPLETE AND ACCEPTED.~~

Designer Note:
As noted in Section 440-11, School Speed Limit Sign assemblies and Crossing Sign
assemblies are addressed separately in this manual. Plan Note 442-50 is a generic
template that may be applied to permanent electrical or electronic devices used
on ODOT sign, signal or ITS projects powered by batteries and recharged by solar
panels. This includes, but is not limited to, roadway signs and beacons, equipment
utility/convenience lighting, remote monitoring stations and similar equipment.
In addition to the text above, include in the As-Per-Plan Note a full description
of the construction item and a method of measurement. This template is not intended
for use on devices used for temporary traffic control since the requirements for
those items are typically covered under their respective standards and/or specifications,
and the devices are not retained by ODOT after construction.~~
