636.20 Temporary Traffic Signal S Or Temporary Lighting :

636.20.1 Temporary Traffic Sign als: Temporary traffic signal work may involve

temporary modifications to existing permanent traffic signals or the installation of temporary signals. Temporary signal installations may entail the installation of traffic signals and associated equipment using wood pole supports, or the use of portable temporary traffic signal trailers. Individual signals or trailers at specific project Plan designated locations shall be interconnected and programmed to operate in a coordinated manner as a system. Tempora ry traffic signal work shall consist of furnishing, installing, maintaining, adjusting, and subsequent removal of various types of traffic signal components and equipment as necessary due to the maintenance of traffic plan. It shall include, but not be li mited to, temporary traffic signals and traffic signal interconnections to be installed, and temporary modification to permanent traffic signals in accordance with Section 660 and Subsection 715.42 of the Specifications.

636.23 Method of Measurement :

The quantities of work done will be measured as follows:

636.23.1 Aggregate: The quantity of "Aggregate for Maintaining Traffic" will be

measured in tons of aggrega te applied and accepted. The number of tons shall be determined by the total of the weights shown on receipted railroad freight bills when materials are shipped by rail; by actual measured displacement of barges certified by the producer when water shipm ents are made, providing materials delivered by the methods are not stockpiled or stored; or determined by the Contractor from the total of 536 weigh slips for each vehicle load weighed on an approved standard scale or from digital printout slips from an autom atic batching plant, and certified by the Contractor to be correct. Truck scales shall be provided by the producer or Contractor, except that truck scales are not required where the material is weighed at properly calibrated automatic batching plant facilities which are equipped with digital print -out equipment. The scales shall be of sufficient size and capacity to weigh the heaviest loaded trucks that are used for delivery of the material. All truck scales shall be mounted on solid foundations which will insure their remaining plumb and level. All truck scales shall be inspected and sealed by the West Virginia Division of Labor, Bureau of Weights and Measures, or other appropriate agencies of the State or its political subdivisions. The Division may , at its option, accept inspection and sealing by out of state agencies when the material is weighed outside West Virginia. A weigh person shall be provided by the producer. The weigh person shall certify that the weight of the material, as determined e ither by the truck scales or from the digital print -out of the weights, is correct. Each truck shall be weighed empty prior to each load, except at automatic batch plants approved to operate without truck scales. A digital recorder and print -out shall be required on all truck scales. The digital recorder shall produce a printed record of the gross, tare and net weights, and the time, date, truck identification and project number. Provision shall be made for constant zero compensation and further prov ision shall be made so that scales may not be manually manipulated during the printing process. The system shall be interlocked so as to allow printing only when the scale has come to rest. In case of a breakdown of the automatic equipment, the Engineer may permit manual operation for a reasonable time, normally not to exceed 48 hours, while the equipment is being repaired.

636.23.4 Temporary Structures: "Temporary Structures for Maintaining Traffic", as

detailed on the Plans or called for by the Engineer, shall be on a lump sum basis for completing, maintaining and removal of the work. Earthwork required for erection or removal of the structure, not measured and paid for by a specific item, shall not be measured or paid for and shall be incidental to Item 636005 -*, Temporary Structure For Maintaining Traffic.

636.23.5 Pilot Truck and Driver: "Pilot Truck and Driver" shall be on a per day basis

and shall include auxiliary barriers and warning signs of all necessary types used in conjunction with the pilot truck.

636.23.6 Traffic Control Devices: "Traffic Control Devices" will be measured by the

number of units of traffic control devices used and accepted. The relative value of each traffic control device in units shall be as shown in the traffic control device rate schedule. The total units of traffic control devices shown in the Contract is an estimated amount only and may be adjusted up or down by the Engineer in accordance with the needs of the project. When more than one sign is attached to a post(s), mount(s) or barricade, the signs will be measured as a sign assembly and not as individual signs. The price bid per unit of traffic control devices shall include furnishing, maintaining and remo ving, filling drums with sand as required, providing sand bags as ballast on barricades, replacement batteries for flashers, turning, covering or otherwise causing signs to be unreadable to traffic when the message does not pertain to the existing conditio n and all other miscellaneous items required for maintaining traffic. 537 Traffic control devices completely destroyed by traffic or any other means shall be replaced by the Contractor, with no additional payment to the Contractor. A payment of ¼ the rate shown shall be made to the Contractor for any traffic control devices that the Contractor moves more than 500 feet when directed by the Engineer. This rate shall not apply for continuous type operations such as resurfacing projects. Payment for continuo us type operations shall be made for the initial placement only. No additional compensation will be made for the moving of traffic control devices made necessary due to the nature of continuous type work. When Cones are specified as the temporary channe lizing device in a project, the Contractor may, at their option, utilize Channelizer Cones in lieu of Cones. However, the unit value assigned to the Channelizer Cones in this case shall be equal to the established unit value assigned to Cones. TRAFFIC CONTROL DEVICES RATE SCHEDULE Device # Description Value in Units Each Traffic Control Device 1 Signs on portable mounts and barricades (Total sign area 16 sq. ft. or greater) 170 2 Signs on portable mounts and barricades (Total sign area less than 16 sq. ft.) 80 3 Signs on permanent posts (Total sign area 16 sq. ft. or greater) 180 4 Signs on permanent posts (Total sign area less than 16 sq. ft.) 90 5 Barricades -Type I 35 6 Barricades -Type II 60 7 Barricades -Type III 90 8 Drums 60 9 Cones 5 10 Vertical Panel or Ground Mounted Delineators 10 11 Barrier or Guardrail Mounted Delineators (Bid Incidental to Barrier or Guardrail) 0 12 Channelizer Cones 40 13 Oversize signs 300 Payment for furnishing, installing, and maintaining the work area signs indicating fines shall be as part of Item 636011 -*. “Traffic Control Devices .” And all the previous provisions of this Article shall apply.
