Any trash at the transition from barrier wall, guardrail, cable rail, to grass areas must be removed by hand and/or mechanical means.

This includes all areas swept.

The estimated number of shoulder miles per cycle of Routine Sweeping is 17.4 miles. Three (3) cycles will be performed each year. When all sections are completed and accepted, a cycle is completed. This contract is for sweeping of the median jersey barrier on Interstate I-95 northbound and southbound lanes from milepost 97 to milepost 107 north of Selma in Johnston County.

The number of cycles and sweeping shoulder mileage is an estimate and may be increased or decreased by written authorization of the Engineer and/or his representative. No claims may be filed due to reduction of quantities. No price adjustments will be made due to reduction of quantities.

The work shall include furnishing of all labor, equipment, tools, materials, transportation, traffic control, and disposal necessary for the prosecution and completion of the work.

SWEEPING - PROSECUTION OF WORK

Notification of need for sweeping roads will be made by the Engineer and may be made by email, telephone call, or fax.

Any of the above methods shall be considered sufficient. Notification will be made a minimum of 7 days prior to need.

The Engineer will provide the Contractor with a start date, start time and location. Should the Contractor fail to begin work within seven calendar days of the start date provided by the Engineer, the Contractor will be found in default and the contract cancelled. Default may lead to Contractor being removed from the “Directory of Transportation Firms” for a minimum of one year.

ROUTINE SWEEPING

This item consists of the sweeping, cleaning and removal of any foreign matter by brooming, suction or other approved method from designated pavement areas, paved shoulders adjacent to the travel lanes, paved shoulders next to barrier walls, curb and gutter, ramps, gore areas, bridges and transitions from hard surfaces to grass areas. Items too large for removal by the mechanical means mentioned above shall be removed by other mechanical methods or by hand.

The designated area is a swath adjacent to a barrier wall or the outside edge of the paved shoulder. A swath begins at the barrier wall, curb, outside edge of paved shoulder or the bridge curb/rail and shall be a minimum of ten (10) feet in width.

The sweeping operation shall not cause material to be thrown into a travel lane and at no time shall material be swept across a travel lane.

Additional Sweeping This item consists of the sweeping, cleaning and removal of any material from adjacent roadways, for short distances, intersecting the system roadways as directed by the Engineer between sunset and sunrise (Night) or between sunrise and sunset (Day).

Equipment Requirements The Contractor shall furnish equipment of sufficient type, capacity, and quantity to safely and efficiently perform the sweeping work. The Contractor shall display the company name on each piece of equipment.

The Contractor shall demonstrate to the satisfaction of the Engineer that sweeping equipment to be used in the work is in good working condition and suitable for performing the required work. Sweepers used in the cleaning operation may be brush/vacuum, mechanical, or regenerative air, or may be a combination of industrial types.

Removal and Disposal of Debris Removal and disposal of all materials shall be the responsibility of the Contractor. Disposal of the materials shall be made in either a public or private sanitary landfill approved and permitted by the State of North Carolina Solid Waste Management Division. All costs involved with the disposal of material shall be considered incidental to the unit prices included in the contract and shall be included at no additional cost.

A sweeping cycle will not be considered to be completed and accepted by the Department until the original “DUMPING TICKET” issued to the Contractor for disposal of materials is presented to the Department’s inspector.

Stockpiling of debris on the right of way shall not be permitted and all work will be suspended if contractor is charged with illegal dumping.

THIS CONTRACT WILL BE TERMINATED IMMEDIATELY IF THE CONTRACTOR IS FOUND GUILTY

OF ILLEGAL DUMPING.

Quality Completed work areas shall be clean and free of all accumulated debris immediately after sweeping as determined by the Engineer’s inspector.

The Contractor shall correct any deficiency no later than seventy-two (72) hours following receipt of such notice.

The Department of Transportation’s inspector will maintain a daily log of completed work and will verify completion of the Contractor’s work with the Contractor upon completion of a cycle.

In the event of a road rehabilitation or improvement project where cleaning is scheduled, that portion of cleaning cycle will be deleted from the appropriate list at the direction of the Department. The section(s) of road(s) deleted may be re-entered at the first scheduled cycle following completion of the road rehabilitation or improvement project.

Prior to re-entering any such road (rehabilitation or improvement project) into the cycle, Department personnel will make a field inspection with the Contractor to determine what cleaning will be required by others. In no event will the Department allow the sweeping contractor to perform initial cleaning of a re-entered road following a rehabilitation or improvement project.

Inspection All work will be subject to inspection by the Engineer at any time. The Engineer or designated representative will make periodic (next day) inspections of the completed work. It shall be the responsibility of the Contractor to keep the

Engineer informed of his/her proposed work plan and to notify the Engineer 48 hours before work is started and within 24 hours after work is completed. It shall also be the responsibility of the Contractor to submit written reports of work accomplished on a frequency to be determined by the Engineer.

It is intended that the work will be completed in a professional manner. These specifications and special provisions are result oriented. Although the main purpose of this contract is to accomplish road-sweeping operations on State roadways, the Contractor will encounter objects larger than what a vacuum or mechanical sweeper can remove.

The Contractor shall remove vehicle parts, tires, tire parts, large stones, boxes, tree limbs, wood, cable, etc. by hand if vacuum or mechanical means are unsuccessful.

Method of Measurement and Basis of Payment The quantity of routine sweeping to be paid for will be the actual number of shoulder miles swept. Highway mileage will be determined from NCDOT county maintenance maps, except in the case of dispute or obvious error, when actual mileage shall be measured. Normally, one map mile of two-lane undivided highway will equal two (2) shoulder miles, and one map mile of multi-lane divided highways with grassed median or barrier will equal four (4) shoulder miles. It is understood that during the course of the contract, routes may be added to or deleted from the contract. It will be the responsibility of the Contractor to sweep or not sweep such routes as directed by the Engineer.

All work or items necessary to complete the work other than those listed on the “Bid Proposal Form” will be considered incidental in nature and no additional compensation shall be made.

The quantity of Additional Sweeping to be paid for will be the number of shoulder miles, measured along the surface of the ground which has been swept at the direction of the Engineer.

CONNECTED LANE CLOSURE SYSTEM:

(10/29/2018) (Rev. 2/7/2023)

Description

Furnish, install, operate, maintain, relocate, and remove connected lane closure devices for use on Interstate and Freeway lane closures. The purpose of a Connected Lane Closure System

(CLCS) is to transmit real-time information of active lane closures on Interstate and Freeways for use by the State Transportation Operations Center (STOC), Regional Transportation

Management Centers (TMCs), and 511 systems; and for third party vendors (Mapping, Navigation, Connected Vehicles, etc.) to identify and provide advanced notification of active lane closures to approaching motorists.

Materials

The CLCS shall be designed and built to transmit the location of the real-time lane closure from the START to the END such that the full length of the lane closure is known. The information transmitted shall be approved by each entity, conform to the current version of the USDOT’s

Work Zone Data Exchange (WZDx) specification and be publicly available to NCDOT approved consumers of this data. More information about the WZDx specification can be found at

(https://www.transportation.gov/av/data/wzdx).

The connected lane closure devices shall be capable of wireless communication.

The initial connected device representing the START location shall be designed and attached to the flashing arrow board in such a manner that it is only activated when either the left or right arrows are displayed, not when the flashing arrow board is operated in caution mode. When the lane closure is removed, and the flashing arrow board is turned off or changed to caution mode, the connected device shall automatically turn off simultaneously and its location shall no longer be transmitted. The device shall also have a visual indicator (e.g. an illuminated light either steady burn or flash) to allow clear, visual proof the device is powered on, has established communication and is transmitting. The visual indicator shall not be located such that it potentially creates confusion to the motorists.

A second connected device representing the END location shall be installed on a crashworthy

(e.g. NCHRP 350 or MASH-16) traffic control device. It shall have an easily accessible power switch and a small status indicator light mounted such that it is visible when passing by in a vehicle at operating speed. When switched to the ON position, the light shall indicate the device has established communication and is transmitting. The light may be either steady burn or flashing and shall not exceed one (1) inch in diameter. This second connected device representing the END location may be created virtually by a connected flashing arrow board.

https://www.transportation.gov/av/data/wzdx

TC-11

The devices shall have battery life sufficient to maintain operation for the duration of the lane closure or have the ability to be recharged without deactivating the device or impacting the location of the lane closure information transmitted to the external parties. All costs associated with charging are incidental and shall be included in the cost of the system.

Construction Methods

Connected lane closure devices shall be used on all lane closures on freeways and interstates throughout the project.

A START and END location shall be established by the installed system per grouping of lane closures (single, double, or triple); one attached and wired into the flashing arrow board at the beginning of the first taper. The other at the last traffic control device at the end of the lane closure(s) if the END location cannot be created virtually. Supplemental flashing arrow boards in advance of the first lane closure taper or flashing arrow boards in subsequent lane closures (for double and triple lane closures) shall not be transmitting if equipped with connected devices.

Subsequent lane closures occurring downstream of where all lanes have been reopened and lane closures in the opposite direction of travel will require additional connected devices.

The second connected lane closure device shall be manually turned ON and OFF by crews installing and removing the lane closure unless the device can be controlled or virtually created by the initial connected device. The unit shall be turned on immediately upon installation of the lane closure and turned off immediately upon removal of the lane closure.

Once installed, the Contractor shall verify that the connected lane closure devices are transmitting information prior to leaving the device unattended and re-verify transmission every

72 hours for long-term installations.

Technical Requirements

The connected devices shall run continuously during any active lane closures for the length of the contract.

The GPS within the connected devices shall have a horizontal accuracy of 10 feet, 95% of the time.

The system shall send real-time alerts to designated NCDOT personnel when the flashing arrow mode or direction is changed. The alert shall be within 5 minutes of the actual change.

The connected device information, including the location, transmission status, and battery status shall be transmitted within five (5) minutes of initiation and updated every thirty (30) minutes to the central server.

TC-12

The contractor shall provide multiple logins to a secured server (e.g. vendor dashboard) that provides real-time and historic status. The status must be exportable, within 24 hours, in .csv or

.xls format and include data for date, display direction, time on, time off, and GPS coordinates.

The historic logged information shall be available to CLCS users 24/7/365 during the length of the entire construction phase. All logged information from the project shall be retained by the

Contractor and be available to the NCDOT for at least one (1) year after the contract ends.

Information shall include timestamps, device name, flashing arrow mode, communication status, battery voltage and GPS location.

The battery voltage shall be collected at least once an hour. The information shall be stored and available for troubleshooting. To prevent communication loss, the system shall transmit an alert via E-mail or SMS to designated personnel if the battery voltage of a device is under a specified threshold.

The CLCS shall provide an immediate electronic alert (e.g. via E-mail or SMS) to the Traffic

Control Supervisor or other designated individual if a device is not transmitting its position for a period of 30 minutes or more.

The outputs from the connected device on the arrow board and the downstream connected (or virtual) device at the end of the lane closure shall be easily identifiable as a single system, either by sequential device IDs, identical project names, or other method as approved by the Engineer.

Additional pairs on the project shall have unique identifiable information such that it is not confused with another project system.

Measurement and Payment

Connected Lane Closure System will be measured and paid as the maximum number of connected systems acceptably placed and in use at any one time during the life of the project.

Each lane closure system may be satisfied by one of the following:

Two (2) connected lane closure devices; one connected to the flashing arrow board and the other on a crashworthy device at the downstream end of the lane closure.

One (1) connected lane closure device connected to the flashing arrow board that can generate a virtual END location with 50’ accuracy.

All devices for each system must be functioning properly to receive payment for the system. No payment will be made for a system until all devices are satisfactorily installed and operational at the device and on the vendors dashboard. A copy of the device status reporting should be provided by the contractor every 2 weeks.

TC-13

The price for each connected lane closure system will cover all material, labor, maintenance,…
