Statement of Work

The following Contractor will assist the Bureau of Indian Affairs, Western Navajo Agency - Branch of Transportation (BIA, WNA-BOT), in a new permanent pavement markings and re-striping on existing permanent pavement markings maintenance activity on several BIA routes N15(1), N15(2), N15(3), N15(7A-1), N15(9), N15(11), N15(12), N16(1), N16(2), N16(3), N16(4), N16(5), N20(1), N20(2), N21(1), N21(2), N21(3), N21(3A), N24, N101(4), N101(5-2), N101(5-3), N101(7), N106, N128, N151, N221(1), N221, N222, N607(1), N608(1), N6330(1), N6331(2), N6331(1-2), N6331 & N6465 within the WNA-DOT Road Inventory. The maintenance activity consists of the Contractor utilizing and placement of the high-build waterborne traffic paint (Type C) with Type 1 and Type 3 glass beads. The quantities for each BIA Routes are identified by the total lengths in Feet for each solid white lines, solid yellow lines, broken white lines and the broken yellow lines. The quantities also include the letterings of “Stop Bar”, “Crosswalk”, “only”, “single arrows”, “Combo Arrows” and “yield”.

Contractor’s Responsibility

The Contractor will mobilize on and off the project site involving personnel and equipment furnished by the contractor to perform the necessary work. The mobilization includes the travel cost for the personnel.

The Contractor will place a 4-inch-wide striping of each type of strip mentioned below for all BIA paved roads within Western Navajo Agency. The total estimated quantities of the High-Build Waterborne Traffic Paint (Type C) with Type 1 and type 3 Glass beads for pavement Markings is 2,513,747.8 Feet for the Contractor to strip for WNA- DOT. In Addition, The Contractor will utilize Thermoplastic Markings with type 1 Glass Beads for the “only” letterings, single arrows, combo arrows, yield and crosswalk. The Contractor shall refer to FP24 (Standard Specification for Construction of Roads and Bridges on Federal Highway Projects) section 634 Permanent Pavement Markings for this striping activity.

The Contractor is responsible for providing the actual field quantities to be striped at the time of completion of the work.

The Contractor is responsible for obtaining a storage or yard for storing their equipment while on the project site.

The Contractor shall be responsible for any costs related to equipment and labor stand-by, if applicable.

The Contractor shall be responsible for any damages to the existing obstructions at their own cost.

BIA’s Responsibility

The BIA will keep track of the striping quantities. The quantities will be cross referenced with the Contractor.

Material

634.02 Conform to the MUTCD and the following Section:

Traffic signing and marking material 718

Construction Requirements

634.03 General. Where existing and final marking locations are identical, stake the limits of existing markings before starting pavement work.

Submit manufacturer’s SDS and product data sheets at least 7 days before applying markings. A field demonstration may be required to verify the adequacy of the material.

Ship marking material containers plainly marked with the following information as appropriate for the material being provided:

(a) Manufacturer’s name and address;

(b) Name of product;

(c) Lot and batch numbers;

(d) Color;

(e) Net mass and volume of contents;

(f) Date of manufacture;

(g) Date of expiration;

(h) Statement of contents;

(i) Mixing proportions (if mixing of components is required); and

(j) Safety information.

Establish marking patterns and locations according to the MUTCD and as shown in the plans.

In curve widening areas, establish the edge line markings at the limits of the traveled way and the centerline markings equal distance between the edge lines.

Remove loose particles, dirt, tar, grease, and other deleterious material from the surface to be marked.

Where markings are placed on rigid pavement less than 1-year old, clean the pavement of laitance and curing compounds.

Remove temporary markings the same day permanent markings are applied. Remove temporary and conflicting makings according to Subsection 635.14 before applying permanent markings.

Wait at least 14 days before applying markings on new asphalt pavements or new asphalt surface treatments. Apply markings to a clean, dry surface and according to the manufacturer’s recommendations.

Produce markings that are clean-cut and uniform in appearance by day and night.

Current state-approved marking material may be used if approved.

Apply glass beads at the rate, type, and timing according to the manufacturer’s recommendations and immediately following marking application to ensure adhesion.

Protect markings from traffic until dried to a no-tracking condition. Remove tracking marks, spilled marking material, markings in unauthorized areas, and defective markings.

634.04 Solventborne Pavement Markings (Type A). Apply markings when pavement and air temperatures are at 35 °F and rising. Do not heat the markings above 120 °F. Spray markings to a 15-mil minimum wet film thickness or at a rate of 107 square feet per gallon.

On new asphalt pavements or new asphalt surface treatments, apply two coats of markings and glass beads.

Apply second coat after first coat is track free.

634.05 Waterborne Pavement Markings (Type B). Apply markings when pavement and air temperatures are 50 °F and rising.

Do not heat the markings above 120 °F. Spray markings at a 15-mil minimum wet film thickness or at a rate of 107 square feet per gallon.

On new asphalt pavements or new asphalt surface treatments, apply two coats.

634.06 High-Build Waterborne Pavement Markings (Type C). Apply markings when pavement and air temperatures are 50 °F and rising.

Spray markings at 25-mil minimum wet film thickness or at a rate of 71 square feet per gallon.

634.07 Epoxy Pavement Markings (Type D). Apply epoxy when pavement and air temperatures are 35 °F and rising. Heat components according to the manufacturer’s recommendations. Apply to a 25-mil minimum dry film thickness or at a rate of 71 square feet per gallon.

634.08 Thermoplastic Pavement Markings (Type H). Apply thermoplastic when pavement and air temperatures are 50 °F and rising. Heat thermoplastic according to the manufacturer’s recommendations.

Apply an epoxy resin primer and sealer according to the thermoplastic manufacturer’s recommendations if placing markings on pavements more than 2-years old, oxidized, or having exposed aggregates. Allow the primer and sealer to dry.

For edge lines, apply thermoplastic to a 60-mil dry film thickness. For other lines, apply thermoplastic to a 90-mil dry film thickness.

634.09 Preformed Pavement Marking Tape (Type J). Use preformed marking tape containing retroreflective beads. Install to form a durable, weather resistant bond to the pavement. Apply preformed markings according to the manufacturer’s recommendations.

634.10 Methyl Methacrylate Pavement Markings (Type L). Apply a two-component methyl methacrylate marking at a minimum thickness of 60 mils for longitudinal markings and 120 mils for transverse markings and symbols. Apply markings when pavement and air temperatures are between 40 °F and 105 °F. Apply according to the manufacturer’s recommendations.

634.11 Pavement Markers. Install raised and recessed pavement markers when the pavement and air temperatures are 50 °F and rising. Apply pavement markers with an epoxy resin adhesive according to the manufacturer’s recommendations when the pavement is dry. Space the markers according to the MUTCD and as shown in the plans.

634.12 Acceptance. Material for permanent pavement markings and markers will be evaluated under Subsections 106.02 and 106.03.

Applying permanent pavement markings and markers will be evaluated under Subsections 106.02 and 106.04.

Measurement

634.13 Measure the Section 634 pay items listed in the bid schedule according to Subsection 109.02 and the following as applicable:

When two coats of markings are required, measure each coat.

When measuring pavement markings by the linear foot or mile, measure the length of line applied along the centerline of each line applied regardless of color. Measure broken and dotted pavement lines from end to end of the line including gaps. Measure solid pavement lines from end to end of each continuous line. Measure line quantities based on a 4-inch-wide line. For line widths greater than 4 inches, adjust the measured length of line in the ratio of the required width to 4 inches.

When measuring pavement markings by the square foot, measure the number of square feet of line, symbol, or letter marking based on the marking area shown in the plans. If not shown, measure the area of each marking in place to the nearest square foot.

Payment
