4. Preconstruction Submittals: All of the following submittals are to be submitted and approved prior to beginning work:

a. Paint and Reflective Beads: Per Specification UFGS 32 17 23, Paragraph 1.3, provide SD-03, SD-06, and SD-07.

b. Existing Conditions Submittal: (1) Contractor is to evaluate all existing pavement markings for conformance to ETL 04-2

(Change 2). If any of the existing pavement markings deviate from the dimensions given in ETL 04-2 (Change 2), the contractor is to bring it to the attention of the Contracting Officer Representative and note the deviation in the Existing Condition Submittal. (2) Contractor is to evaluate, bring to the attention of the Contracting Officer Representative, and document in the Existing Condition Submittal any pavement damage and/or existing condition of the existing pavement markings and paving that would affect the pressure washing or application of pavement markings.

c. Pressure Washing and Application Plan: Contractor is to provide a pressure washing and painting application plan for pressure washing and painting of airfield markings to include anticipated time for each type/area of pavement marking, any requests for airfield closure, and anticipated period of performance for elements of project. This submittal will be for information to help facilitate a preconstruction meeting with the Airfield Manager.

d. Quality Control Plan: Contractor is to provide quality control plan to include but not limited to (1) Pressure Washing:

controls or processes to preclude pavement damage; (2) Application: maintaining specified application rates of beads and paint, ensuring clean surfaces prior to paint application, ensuring dimensions of existing pavement markings IAW ETL 04-2, ensuring there is no unintended overspray.

e. Personnel Qualifications: See Specification Section 32 17 23, Paragraph 1.3.2 and 1.3.3.

5. Pressure Wash Existing Airfield Markings:

a. Pressure Wash Test Demonstration: Contractor shall provide a pressure wash test demonstration for contracting officer representative. The Contractor shall test all equipment and demonstrate on the designated pavement work areas the proposed method to be used to pressure wash existing airfield markings. The contractor will vary the range of pressure to produce the most effective cleaning pressure with no damage to existing pavement or pavement markings. The Contracting Officer Representative will designate a test strip within the work area. The test strip shall be as wide as the full operating width of the equipment and at least 15 meters (50 feet) long. The test strip shall be long enough to determine the operating parameters of the vehicle(s) and equipment to be used for the work. The test strip shall be used to demonstrate the effectiveness of the Contractor’s methods and equipment to satisfactorily remove dirt, debris and mold from the existing painted surfaces at the specified removal rate without damaging the pavement marking or pavement surface. The Contracting Officer Representative shall be present at the test area to examine the pressure washer results obtained on the test strip. The test strip shall be the measure of performance required of the Contractor for the paint removal project. The Contractor shall not proceed with the work until the results of the test strip are satisfactory to the Contracting Officer Representative.

6. Application of Airfield Markings:

a. All Markings Shall be Painted on Existing Schemes: All existing schemes are in accordance with ETL 04-2. If existing markings are not within tolerance of ETL 04-02, contractor is to bring it to the attention of the Contracting Officer’s Representative.

b. Runway - Application of Pavements Markings: The Contractor shall clean the existing markings that are to be remarked and remove any loose or poorly bonded paint that would inhibit adhesion of the new marking to the pavement surface. Paint that is intact and bonded to the pavement does not have to be removed. The Contractor shall remove dust, dirt, peeling or poorly bonded paint, and granular surface deposits from all other pavement areas by sweeping, blowing with compressed air, and/or rinsing with pressurized water. Any areas exposed to rain or traffic after cleaning shall be cleaned again before marking.

c. Paint Application Test Strip Demonstration: Contractor shall provide a Test Strip Demonstration as follows:

(1) Test Stripe Demonstration. Before beginning work, the Contractor shall mark test stripes within the work area to demonstrate the proposed materials and equipment to be used for the contract. Apply separate test stripes in each of the line widths and configurations required in the contract, using the equipment proposed for the contract. Mark the test stripes long enough to determine the proper speed and operating pressures for the vehicle(s) and machinery, but not less than 50 feet.

(2) Demonstration of Application Rates. In applying the test stripes, the Contractor shall demonstrate the ability to comply with the application rates as indicated below. Document the equipment speed and operating pressures required to meet the specified rates in each configuration of the equipment and provide a copy of the documentation to the Contracting Officer Representative before proceeding with the work.

ATCH 10 (3 of 7)

(3) Demonstration of Retroreflective Values. After the test stripes have cured to a “no-track” condition, the Contractor shall demonstrate compliance with the average retroreflective values as indicated below. Take a minimum of four (4) readings on each test stripe with a Mirolux 12 Retroreflectometer, or similar instrument with the same measuring geometry and direct readout in millicandelas per square meter per lux (mcd/m2/lx).

(4) Demonstration of Level of Performance. The Contracting Officer Representative will be present at the test area to observe the result obtained on the test stripe and validate the operating parameters of the vehicle(s) and equipment. The application of test stripes shall be used to determine if the proposed methods and equipment can achieve the level of performance required for the contract. If accepted by the Contracting Officer Representative, the test stripe shall be the measure of performance required of the Contractor for the marking project. The Contractor shall not proceed with the work until the results of the test stripes are satisfactory to the Contracting Officer Representative.

d. Paint Application Rates: Paint and glass beads will be applied as follows (UFGS 32 17 23, Paragraph 3.3.1.1.1): Reflective Markings: Pigmented binder shall be applied evenly to the pavement area to be coated at a rate of 121 plus or minus 6 square feet per gallon. Glass spheres shall be applied uniformly to the wet paint on airfield pavement at a rate of 8 plus or minus 1.0 pound of glass spheres per gallon of paint.

e. Retroreflectivity Levels: After all work is completed, the Contractor shall collect and record readings for white retroreflective markings to ensure they provide a reasonable level of retroreflectivity for night operations. The minimum acceptable average for white markings will be 200 millicandelas per square meter per lux (mcd/m2/lx) (measured with Mirolux 12 Retroreflectometer). The Contractor shall document a retroreflectivity reading for forty retroreflectometer. The reading shall be computed by averaging a minimum of 4 readings taken within the area at random locations. Areas not meeting the retroreflective requirements stated above shall be re-marked at the Contractor’s expense.

f. Placement of Markings. The Contractor shall ensure that all markings are installed properly and placed in strict compliance with ETL 04-02. The longitudinal edges of markings shall not vary from a straight line by more than 25 millimeters (1 inch) per 15 meters (50 feet). The overall dimensions of the markings shall not vary from ETL 04-02 by more than 5 percent. Any markings that are improperly placed or fail to meet the requirements of this specification will be removed and reinstalled at the Contractor’s expense. Materials used for repairs shall be from the same lot and batch as those approved for the performance of the contract or shall be subjected to the same requirements and approved by the CO or authorized representative prior to beginning repairs.
