.8--Snap-Back Delineators. Snap-back delineators shall be installed in accordance

with the manufacturer's recommendations and at the locations shown on the plans or

directed by the Engineer. Delineators that are damaged by traffic to the extent that they

are non-functional shall be replaced as quickly as possible.

.9--Portable Median Barrier. Portable median barriers shall be installed in

accordance with the manufacturer’s recommendations. The barriers shall be installed at

the locations shown on the plans, or as directed by the Engineer.

.10--Changeable Message Sign. Each changeable message sign shall be installed

and continuously operated at the location selected by the Engineer on State right-of-way.

The Contractor is advised that selected locations may be outside the planned limits of the

project. The Contractor shall perform all work necessary for preparation of the site selected

and approved by the Engineer, to ensure maximum safety and sign visibility for the

traveling public and may be required to remove any temporary work at a later date as

directed by the Engineer. The Contractor will also place a minimum of two plastic drums

in advance of the sign and one beside the sign as long as it is in use. The Contractor shall

be required to move the sign to a new location if directed by the Engineer.

The Contractor may be permitted to bring electric power from outside the normal right-of-

way for operation of the equipment if the Department determines that the installation

operation will not be hazardous to the traveling public. The Contractor will be required to

secure a permit from the Department prior to any work by the power company on the right-

of-way. The entire cost of providing electrical service, power to operate the equipment,

and removal of the power source from the right-of-way shall be borne by the Contractor.

The changeable message sign(s) will remain the property of the Contractor after the

Engineer determines that there is no further need for the sign(s) on the project.

.11--Glare Paddles. Glare paddle installation shall consist of furnishing, installing,

maintaining, removing and relocating glare paddles as required. Glare paddles shall be

placed atop precast median barriers, or other devices, at locations shown in the plans, or as

directed by the Engineer.

The paddles shall be six to nine inches (6" to 9") in width, 24 to 36 inches in height, and

spaced a maximum of 24 inches apart. The paddles shall be attached to the top of the

devices in accordance with manufacturer’s recommendations at a 22 degree angle. A

yellow high-intensity reflective strip shall be attached vertically to each side of one of the

paddles such that the spacing is 10 feet apart. Unless otherwise directed, these strips shall

be placed on the edge of the paddle adjacent to traffic. These reflective strips shall be made

of 2-inch by 12-inch material conforming to the requirements of Subsection 721.06 of the

Standard Specifications.

All glare paddles shall be properly maintained. Maintenance will include replacement of

damaged or missing blades, improper reflectorization, and any other portions of the

installation that may fail, for the entire length of time that the paddles are in place. Cleaning

of the reflective material shall be accomplished by any means that does not damage the

paddles and in a manner that is not hazardous to traffic. Cleaning shall be accomplished

on an as-needed basis or as ordered by the Engineer.

476

Section 619 Section 619

The Contractor shall relocate the glare paddles as required during construction at no

additional cost to the State.

After completion of the work, glare paddles and attachments shall remain the property of

the Contractor.

619.04Method of Measurement. Traffic control devices will be measured one time only

by the units indicated. When moved from the original location to other locations, as

required by the contract or as directed by the Engineer, traffic control devices will not be

measured for additional payment except when the contract includes the pay item, "Remove

and Reset". The total pay quantity for each traffic control device excluding traffic stripe

shall not exceed the maximum number of installations in place at any given time during

the life of the contract. Unless otherwise provided, replacement of devices will not be

measured for payment.

Temporary stripe, completed and removed in accordance with the requirements of this

Section, will be measured by the mile or by the linear foot, as indicated, from end-to-end

of individual stripes. In the case of skip lines, the measurement will include skips. The

length used to measure centerline, lane lines and edge stripes will be the horizontal length

computed along the stationed control line. Detail traffic stripe will be measured by the

linear foot from end-to-end of individual stripes. Measurement will be made along the

surface of each stripe and will exclude nominal skip intervals where specified. Stripes

more than four inches in width will be converted to equivalent lengths of four-inch stripe.

Legend, which is to include railroad markings, pedestrian crosswalks and stop lines, will

be measured by the square foot or linear foot. Pay areas of individual letters and symbols

will usually be shown on the plans and measured by the square foot. Transverse railroad

bands, pedestrian crosswalks and stop lines will generally be measured by the linear foot,

and stripes more than four inches in width will be converted to equivalent lengths of four-

inch widths.

Each impact attenuator installation, including one replacement package, will be measured

per each installation as shown on the plans. Replacement packages, excluding the package

included with the initial attenuator, will be measured per each in accordance with these

specifications.

Initial snap-back delineators will be measured per each. Replacement will be measured as

follows:

Changeable message signs, as described above, will be measured per each. When directed,

separate measurements will be made for items included in the contract and required for

temporary site preparation for the sign as referenced in Subsection 619.03.10. Materials

for which no pay items are included in the contract will not be measured for separate

payment. Separate measurements will not be made for moving the changeable message

sign to a new location, but materials used for which pay items are included in the contract

and are necessary for repositioning the sign as directed by the Engineer will be measured

477

Section 619 Section 619

for separate payment. Removal of materials used for site preparation for changeable

message signs will not be measured for separate payment.

Portable traffic signals of the type specified will be measured per each.

The lengths of median barrier, including remove and reset median barrier, will be measured

per linear foot by multiplying the number of commercial lengths installed by the nominal

length of the barrier.

619.05Basis of Payment. Traffic control devices will be paid for at the contract unit

price for the units specified. Devices that have been measured for payment and

subsequently require repair or replacement will be dropped from payment on future

estimates unless satisfactorily repaired or replaced.

Payment for devices for which no pay items are contained in the contract will be included

in the unit prices of contract items and/or in the lump sum contract price for Maintenance

of Traffic.

Payment for items required by the Engineer for temporary location of the changeable

message sign, and for which pay items are included in the contract, will be made by the

individual pay item. No additional payment will be made for working outside the planned

indicated project limits.

Payment for removal of materials used for site preparation at changeable message sign

locations shall be included in the contract price for Maintenance of Traffic.

Portable traffic signals of the type specified will be paid for at the contract unit price per

each, which price shall be full compensation for furnishing, installing, testing, operating,

relocating a complete portable traffic signal as required, integration, configuration, and all

other materials, equipment, labor, tools and incidentals necessary to complete the work.

The prices thus paid shall be full compensation for completing the work.
