1.2 SUBMITTALS

Government approval is required for submittals with a "G" designation; submittals not having a

"G" designation are for Contractor Quality Control approval. When used, a designation following the "G" designation identifies the office that will review the submittal for the

Government. The following shall be submitted in accordance with Section 01 33 00

SUBMITTAL PROCEDURES:

SD-04 Samples

Rubber and paint removal samples

SD-07 Certificates

Schedule of work

High-pressure rubber and paint removal equipment

1.3 RADIO COMMUNICATION

No personnel or equipment will be allowed on the runway until radio contact has been made with the Control Tower and permission is granted by the Control Tower. A radio for this purpose will be made available by the Contracting Officer or required of the Contractor and approved by the

Contracting Officer. The Contractor shall be in contact with the Control Tower at all times during the removal work.

1.4 EMERGENCY LANDINGS AND TAKEOFF

Emergencies shall take precedence over all Contractor operations. Upon notification from the

Control Tower of emergency landing or imminent takeoff, all operations shall be stopped immediately and all personnel and equipment evacuated to an area not utilized for aircraft traffic which is at least 200 feet measured perpendicular to and away from the near edge of the runway.

Equipment shall be able to clear the work area within 3 minutes.

1.5 ENVIRONMENTAL CONDITIONS

Do not perform work when the temperature is below 40 degrees F, during lightning storms, or when the pavement is covered with snow or ice.

1.6 SAFETY

Comply with OSHA 29 CFR 1910.

1.7 SCHEDULE

1.7.1 Schedule of Work

Submit a schedule of work to the Contracting Officer for transmittal to the Operations Officer.

Describe the work to be accomplished; noting the location of work, distances from the ends of runways, taxiways, buildings, and other structures; and indicating dates and hours during which the work will be accomplished. Schedule the work to conform to aircraft operating schedules.

The Government will try to schedule aircraft operations so as to permit the maximum amount of time for the Contractor's work. However, in the event of any emergency, intense operational demands, adverse wind conditions, and other unforeseen difficulties, discontinue all work at locations in the aircraft operational area. Keep the approved schedule of work current and notify the Contracting Officer of any changes prior to beginning each day's work.

1.8 EQUIPMENT

1.8.1 Equipment Data

Submit descriptive data of high-pressure rubber and paint removal equipment including area of coverage per pass, range of water pressures, and water tank capacity.

1.9 QUALITY ASSURANCE

1.9.1 Required Samples

Prior to the start of work, remove rubber and paint on designated test areas not less than 50 feet in length. Use procedures, water pressures, nozzle height, nozzle spacing, nozzle angle, and equipment movement rate to achieve the required degree of rubber and paint removal in accordance with the paragraph entitled "Execution." Submit the test results before any further removal work will be allowed.

PART 2 PRODUCTS

2.1 MATERIALS

Water to be used for high-pressure water equipment will be made available from Government hydrants as shown on the drawings, at no cost to the Contractor. Furnish all equipment and labor for delivery of water from the hydrant to the job site. Notify the Contracting Officer on location of fire hydrants to be used and the respective times of use. Connections to a fire hydrant will be subject to the Contracting Officer's inspection and approval.

2.2 EQUIPMENT

Vehicular-mounted hydraulic system capable of delivering high-pressure water impact upon the pavement surface less or greater than 8,000 pounds per square inch. If high-pressure water is delivered from a spray bar, the nozzles shall be spaced to provide total coverage of the area being treated. The nozzle line shall have adjustable pressure regulators or relief valves and gauges measuring actual line pressure. Equipment shall be supported on pneumatic tires. Provide equipment, tools, and machinery which are safe and in satisfactory condition at all times.

PART 3 EXECUTION

3.1 DEGREE OF REMOVAL

Degree of removal will be specified in Task Order.

3.2 RATE OF REMOVAL

Rate of removal will be specified in Task Order. Do not permit high-pressure water application to remove the existing pavement surface.

3.3 WATER PRESSURE

Provide water pressure impact upon the indicated pavement areas sufficient to remove the designated rubber and paint to the required degree of removal without damaging the existing pavement joint sealant, and other airfield appurtenances. Contractor shall be responsible for repairing any damage caused by the removal work.

3.4 REMOVAL OF RESIDUE

Remove all residues from the pavement. Obtain the approval of residue removal and disposal method from the Contracting Officer prior to beginning work.
