00224.00 186 Section 00224 - Temporary Traffic Channelizing Devices
Description
00224.00Scope - In addition to requirements of Section 00221, this Work consists furnishing,
installing, moving, maintaining, inspecting, and removing channelizing devices including, but not limited to, tubular markers, conical markers, surface mounted tubular markers, plastic drums, and delineators throughout the Project area as shown or specified.
Materials
00224.10Tubular Markers - Use tubular markers from the QPL. Use blue plastic markers for
temporary business accesses only. Use orange plasti c markers for all other applications of Work Zone traffic control.
00224.11Conical Markers - Use conical markers from the QPL
00224.12Surface Mounted Tubular Markers - Use surface mounted tubular markers from the QPL
00224.13Plastic Drums - Use plastic drums from the QPL
00224.14Delineators - Use new delineators from the QPL or salvaged reflectorized delineators
(W-1) or (Y-1), as appropriate, and conforming to the requirements of Section 00840 and the following:
00224.15Barricades - Use barricades from the QPL and as shown on the Standard Drawings
Construction
00224.40Tubular and Conical Markers - Install tubular or conical markers as shown or directed
Place tubular or conical markers no more than 10 feet apart along both sides of driveways, streets, and road connections within Work Areas.
Within individual runs of tubular or conical markers, use one shape for the entire run. Conical markers may be use d in place of tubular markers.
00224.42Surface Mounted Tubular Markers - Install surface mounted tubular markers as shown
or directed.
Remove surface mounted tubular marker bases in a manner that leaves any remaining adhesive material with a textured surface condition similar to the texture of the surrounding top Lift wearing Course Pavement surface. Make the surface dull and non-reflective. Remove adhesive from the Pavement surface using a method that will not damage the Pavement surface.
00224.43Plastic Drums - Install plastic drums as shown or as directed
00224.44Delineators - Install traffic delineators as shown or as directed. Install delineators on
temporary barrier and temporar y guardrail as follows:
Space on 50 foot centers. Closer spacing may be required as directed. Use yellow when installed on the left side of traffic. 00224.80 187 Use white when installed on the right side of traffic. Use bi -directional markers for Median applications . Position to face oncoming traffic.
00224.45Barricades - Use and place barricades as shown or as directed
00224.46Pavement Edge Delineation - Place tubular or conical markers to delineate the edge of
Pavement immediately after construction Work removes or obscures painted edge stripes (Shoulder or fog lines). If the left Shoulder is less than 8 feet wide, Type 5 delineators may be used instead of tubular or conical markers, by installing the delineators on the barrier at 25 foot spacing before left hand edge line markings are removed or obscured.
Place tubular or conical markers to delineate the edge of Pavement immediately after construction Work or paving operations create an abrupt or sloped edge drop-off greater than 1 inch in height along the right hand or left hand Shoulder.
Maintain Pavement edge delineation until temporary pavement markings can be applied according to 00225.42. Apply temporary pavement markings within 14 Calendar Days after the painted edge stripe has been removed or obscured. Locate and maintain tubular and conical markers as follows:
Place markers between traffic and the abrupt edge. Space markers as shown for traffic delineators on the Standard Drawings at a maximum spacing of 200 feet. Patrol dail y and restore them to their proper position at least once at the start of each work shift and once at the end of each work shift until the tubular or conical markers are no longer required. Remove markers after a new edge stripe has been painted and new delineators are in place.
Maintenance
00224.60Temporary Traffic Delineation - Evaluate and maintain or immediately replace all
unacceptable temporary tubular and conical markers, plastic drums, surface mounted tubular markers, and traffic delineators wi th acceptable Materials.
Measurement
00224.80Measurement - The quantities of surface mounted tubular markers, replacings urface
mounted tubular markers, temporary plastic drums, temporary delineators, and temporary barricades will be measured on the u nit basis. No measurement of quantities will be made for conical markers or tubular markers.
The quantities for Work Zone Traffic Control Measures will be limited to the following, unless otherwise specified:
The initial installation of quantities necessary to complete the Project based on the Contract Schedule of Items. The initial installation of additional TCD and TCM that the Engineer and Contractor agree are necessary to ensure a safe W ork Zone. The replacement of TCD and TCM damaged by Public Traffic and replaced by the Contractor.
00224.90 188 Payment
00224.90Payment - The accepted quantities of temporary traffic delineation will be paid for at the
Contract unit price, per unit of measurement, for the following items:
Pay Item Unit of Me asurement
Item (a) includes furnishing and installing the complete assembly of each device in its initial location and for removing the device from the surface. Item (b) includes furnishing new or refurbished devices to replace damaged or missing devices.
In item (e), the type of barricade will be inserted in the blank.
Conical markers and tubular markers will be paid for according to 00221.90(b). Payment will be payment in full for furnishing, installing, moving, operating, maintaining, inspecting, and removing the Materials and TCD, and for furnishing all Equipment, labor, and Incidentals necessary to complete the Work as specified, except as covered in 00221.90(b).
TCD items included under this Section damaged by Public Traffic and replaced by the Contractor will be paid for at the Contract price for the Pay Items listed in the Contract Schedule of Items or in approved Contract Change Orders, unless otherwise specified. Payment for replacing damaged TCD will only be made when:
The Engineer orders it. The replacement devices are used on the Project. The damaged devices are disposed of to the Engineer's satisfaction.
00224.91Payment, Lump Sum or Incidental Basis - When the Contract indicates payment for
Work under 00221.98 Payment, Method “B” - Lump Sum Basis or 00221.99 Payment, Method “ C” - Incidental Basis , no separate or additional payment will be made for Work performed under this Section. Payment will be included in payment according to 00221.98 or 00221.99.
