1.07R Traffic Signals A. The following are Hillsborough County’s additions to Section 603 of the FDOT Standard

Specifications for Road and Bridge Construction:

603-3.3 Substantial Completion: Installation is substantially complete when there are only minor discrepancies. These minor discrepancies will have no effect on the operation of the signal. All signals, markings, and signs will have been installed to be considered at substantial completion.

B. The following are Hillsborough County’s additions to Section 611-2 of the FDOT

Standard Specifications for Road and Bridge Construction:

611-2.4.1.1 New Signal Installations: New signals (no signal previously at intersection) will be inspected when the signal is at substantial level of completion. All signals, pedestrian signals and signs, markings, wiring, loops, and video detection will be in place. Minor requirements such as duct seal on conduits, advance signal ahead signs, and overhead illuminated signs may still be outstanding if the reason for lack of completion is significantly justified. The electrical service release will not be sent to the power company until the signal is determined to be at substantial completion by the traffic signal inspector or a deviation is granted by the Manager of Traffic Operations.

C. Replace the existing language of Section 611-3 of the FDOT Standard Specifications for

Road and Bridge Construction with the following:

611-3 Signal Timing: The signal timing will typically be provided by the County. In the case of updated signal installation, the Engineer of Record will provide signal timings when any phasing changes have occurred from the old traffic signal to the new traffic signal. If no changes in phasing have occurred, the existing time sheet may be implemented at the time the signal is swapped over. In the case where a new traffic signal (no signal previously existed) is being installed in a coordinated corridor, the Engineer of Record will provide basic timings and Hillsborough County Traffic Engineering (Timings Section) will provide the coordinated timing plan. The contractor, in all cases, will provide a minimum of 2-week notice prior to activation of new or modified signals to allow sufficient time to review and/or create new timings for the traffic signal. The timings will be reviewed and/or created by Hillsborough County Traffic Engineering or their applicable consultant.

D. The following are Hillsborough County’s additions to Section 611-5 of the FDOT

611-5.2.1 Responsibility for maintenance of existing traffic signal during construction:

The contractor is responsible for all maintenance of the traffic signal at commencement of the project. The maintenance of the traffic signal is defined as repair and/or replacement of any equipment or hardware failures which cause the traffic signal to operate abnormally. This will include any damages caused by accident or criminal behavior to any underground or aboveground traffic signal related facility. Once the replacement signal is operational, the responsibility for maintenance of the new traffic signal will continue to be the responsibility of the contractor until all of the discrepancies or punch list items have been corrected and the traffic signal is deemed “acceptable”. The contractor will be required to respond to any traffic signal complaints from citizens, law enforcement and/or Hillsborough County’s call center.

8 January 1, 2017

611-5.2.2 Responsibility for maintenance of a new traffic signal: The contractor is responsible for all maintenance of the new traffic signal from the moment the construction starts until all discrepancies or punch list items have been corrected and the traffic signal is deemed “acceptable”. The contractor will be required to respond to any traffic signal complaints from citizens, law enforcement and/or Hillsborough County’s call center.

E. The following are Hillsborough County’s additions to Section 620 of the FDOT Standard

Specifications for Road and Bridge Construction:

620-3.1 General: Meet all local electrical codes. Install insulated green No. 4 AWG copper wire for electrical or lightning protection ground from the system ground (electrical service ground rod) to all elements of the traffic signal (pedestrian poles, mast arms, steel pull box lids, etc.). No. 4 AWG insulated green copper wire will be used from the electrical service disconnect to the traffic signal controller ground. The main ground wire from the meter panel to the ground rod will be #4 AWG solid copper wire.

All connections to ground rods and connections where multiple ground wires intersect will be exothermically welded. Connections in the meter can, electrical service disconnect, pedestrian poles, mast arms, traffic signal controller cabinet, etc. will be made with a crimped lug that is bolted to a grounding point or direct connection to a ground buss (usually found in the electrical service disconnect and controller cabinet).

All separately grounded elements at an intersection will be bonded together (exothermically) to form an intersection grounding network and all will be tied back to the primary ground on the electrical service meter panel. The intersecting point for all ground wires in the grounding network will be a pull box adjacent to the electric service meter panel. Refer to the Typical 240/120 VAC Service drawing in the construction plans.

A pull box adjacent to the electrical service meter/disconnect pole will be installed to provide an intersecting point for all the grounding network grounds. The ground wires from all ground network components (i.e., signal poles, pedestrian poles, pull boxes, etc.)

will be brought into this one pull box to be tied to the main ground from the electrical service ground.

Refer to the Hillsborough County Typical 240/120 VAC Service drawing in the construction plans for further guidance on grounding and surge protection device.

F. The following is Hillsborough County’s addition to Section 630-3.2 of the FDOT

G. The following are Hillsborough County’s additions to Section 632 of the FDOT Standard

632-3.1 Number of Conductors: The contractor will determine the number of conductors required for each signal and interconnect cable by utilizing the Contract Documents or contacting the County traffic signal inspector.

For span wire installations using trunk cables, there will be a minimum of three spare conductors for each signal trunk cable used at all signal installations. Install the three spare conductors from the controller cabinet through each signal head disconnect hanger to the furthermost disconnect hanger. Each direction or approach will have its own neutral. Double (2-way) signal heads will not be allowed as this would cause two separate directions to share one neutral. The white conductor in the signal cable will be used for the neutral. For span wire installation using individual cables to each signal head, there will be a minimum of two spare conductors to each signal head (except for potential future 5-section locations). Where the potential exists for a future 5-section, a minimum of three spare conductors will be made available.

For mast arm installations, there will be two spare conductors to each signal head. Each signal head will have an individual cable from the mast arm hand hole to the signal head without any splices or breaks. All mast arms will have a hand hole terminal compartment provided by the manufacture unless specifically deleted by the Engineer of Record. If equipped with a terminal block, a trunk cable will be run to the hand hole continuously from the controller cabinet with at least three spare conductors. If no hand hole exists in the mast arm, each signal head will have a continuous signal cable from the signal head to the controller cabinet with no splices.

For box span wire installations where a pole mounted junction box is stipulated, a trunk cable will be run continuously from the controller cabinet to the junction box. Individual cables will be run from the junction box to the individual signal heads. Each direction will have a separate junction box. The number of spares will be the same as previously stipulated for mast arm installations.

For pedestrian signals, there will be two spare conductors for all pedestrian signals.

Pedestrian poles with a single pedestrian signal will have a minimum of a 5-conductor signal cable. Pedestrian poles with a double (2-way) pedestrian signal will have a minimum of a 9-conductor cable. Double (2-way) pedestrian signals will only be installed with the approval of Traffic Engineering to ensure compliance with ADA requirements. The cables for the pedestrian signals will be a continuous run from the pedestrian signal to the controller cabinet with no splices. All pedestrian buttons will have a separate 2-conductor cable (belden) run from the button to the controller cabinet with no splices. The bare wire for the belden will be tied to ground in the controller cabinet.

All spare signal cable conductors will be terminated on the ground bus in the controller cabinet. The spares in a signal disconnect will be terminated on the terminal strip inside the disconnect. Any other spares (mast arm, signal heads, pedestrian heads) will be

10 January 1, 2017 individually capped or taped. All spares routed from the overhead mast arm signals to the hand hole (terminal compartment) or span wire with junction boxes will be grounded in the hand hole (terminal compartment).

All spare signal cable conductors in the controller cabinet will be labeled as spare and of sufficient length to be utilized for future use anywhere in the controller cabinet. Spare signal cable conductors within the controller cabinet will be terminated to the ground buss.

632-3.2 Protection of Cable: Bell ends must be installed on all conduit ends prior to pulling cable in PVC conduit. Rigid conduit will have a grounding bushing (if appropriate) or a PVC bushing on the rigid conduit end. Grommets must be installed on all metal poles where cable passes through a drilled or manufactured hole unless the opening has been manufactured in such a manner that cable will not be damaged by pulling it through the opening or by the cable laying on the pole opening.

632-3.3.1 Cabling for Span Wire Installations Stipulated to have Junction Boxes: The cables running across a span wire installation will be lashed to the messenger wire using appropriately sized lashing rods. Cable ties will be used only in the area of the drip loops.

NEMA approved water-tight enclosures (junction boxes) will be mounted on each strain pole at each corner of the intersection near the weather head or span wire attachment point. An appropriately sized trunk cable will be run from the NEMA enclosure to the controller cabinet. Individual cables, with appropriate spares, will be installed between the NEMA enclosure and individual signal heads. All terminations in the NEMA enclosure will be terminated on a terminal strip in the NEMA enclosure. The terminal strip will be sized to ensure that no more than three fork terminals will be installed on any one terminal position of the terminal strip. Spare conductors from each signal head will be tied to ground in the NEMA enclosure. All entries into the NEMA enclosure will be with water-tight connectors.

H. The following are Hillsborough County’s additions to Section 634 of the FDOT Standard

634-1 Description. Follow 634-1 adding the following: fiberglass insulators will be installed on the upper span (catenary) at all locations where the span will be underneath an energized power line. This is regardless of the vertical clearance to the power line.

634-3.4 Span Wire Guidance: The 2014 FDOT Design Standard 17727 removed single point attachment as an option for spanning an intersection. Single point attachment is not allowed in Hillsborough County for new installations.

I. The following are Hillsborough County’s additions to Section 635 of the FDOT Standard

635-2 Materials: All communication/ITS pull box lids or pull box bodies will be provided with electronic markers. The electronic markers will either be encased in the pull box cover or the marker will be a drop-in device that will be inside the actual pull box enclosure. The markers will be the standard telephone marker (orange) (101.4Khz) for any communication or fiber optic pull boxes.

11 January 1, 2017

J. The following are Hillsborough County’s additions to Section 639 of the FDOT Standard Specifications for Road and Bridge Construction:

639-4.1 General: Hillsborough County Traffic Operations will obtain the electrical service address from the County’s 911 Streets and Address’ office. All traffic signals’ addresses will end with “1/8” per Tampa Electric Company’s (TECO) direction. All other electrical services (cameras, DMS, lighting load centers, etc.) will not have a fraction after the address.

The traffic signal subcontractor installing the electrical power service assembly will be required to obtain a layout number from TECO by submitting a Commercial Service Application prior to installation of the electrical power service. Once the layout number is obtained the traffic signal subcontractor will arrange to meet the assigned TECO field engineer on sight to confirm exact location and type of feed (overhead or underground).

If the location of the electrical service is required to be changed by TECO, the traffic signal contractor will immediately advise Hillsborough County Traffic Operations so a new, corrected address can be obtained from the County’s 911 Streets and Address’ office.

The contractor will be responsible for any additional costs associated with the installation of the electrical power service.

639-4.5 Meter Base: The meter will be securely fastened to the pole. The service meter/disconnect will not be mounted on the traffic controller cabinet. The meter will be mounted on the nearest traffic signal concrete strain pole, nearest mast arm pole, or separate (specific for electric service) concrete pole. The height of the meter will be based on the requirements of the power company (TECO). The meter will be a bypass type meter that is rated between 100 and 200 amps and approved by the electrical power company. The meter will have the address of the electrical service attached as directed by the electrical power company. The pole, meter, and disconnect will be installed within 15 feet of the point of service. If that point of service is in excess of 50 feet from the controller cabinet, the meter, disconnect and service pole will be installed in close proximity to the point of service and a separate pole and electrical disconnect will be mounted in close proximity or at least within 15 feet of the controller cabinet.

K. The following are Hillsborough County’s additions to Section 650 of the FDOT Standard

650-3.5 Wiring Connections: Each approach will have its own neutral.

For mast arm installations, each signal will have its own signal cable which will terminate in the mast arm hand hole (if so equipped) on a stainless steel equipped terminal strip. If, in the absence of a hand hole and terminal strip, each signal’s cable will be continuous from the traffic signal to the controller cabinet. In cases where there is a terminal strip in the hand hole, the trunk cable will be of sufficient size to allow for at least three spare wires available in the hand hole terminal strip.

For span wire installations with disconnects, each direction will have a separate cable (four cables for a cross intersection and three cables for a T-intersection). There will be no double signal head configurations. Each direction will have a minimum of a 12-conductor cable terminated in the disconnects. For this installation, there will be a

12 January 1, 2017 minimum of 5 spare wires in each cable. The signal cable will be terminated on the bottom portion of the terminal strip inside the disconnect. The signal will be hard-wired to the top portion of the terminal strip inside the disconnect.
