1.6 PROJECT/SITE CONDITIONS

1.6.1 Environmental Requirements

1.6.1.1 Weather Limitations for Application

NOTE: I f emer gency mar ki ng at t emper at ur es f r om mi nus 1 degr ees C 30 degr ees F t o 5 degr ees C 40 degr ees F i s r equi r ed, f ol l ow t he r equi r ement s of Ai r For ce Engi neer i ng Techni cal Let t er ( ETL) 97- 16 " Pavement Mar ki ng Syst em f or Low Temper at ur e Applications."

Al l owabl e ai r and pavement t emper at ur e f or appl i cat i on var i es wi t h t ype of pavement mar ki ng mat er i al and manuf act ur er .

Apply pavement markings to clean, dry surfaces, and unless otherwise approved, only when the air and pavement surface temperature is at least 3 degrees C 5 degrees F above the dew point and the air and pavement temperatures are within the limits recommended by the pavement marking manufacturer. Allow pavement surfaces to dry after water has been used for cleaning or rainfall has occurred prior to striping or marking. Test the pavement surface for moisture before beginning work each day and after cleaning. Do not commence marking until the pavement is sufficiently dry and the pavement condition has been approved by the Contracting Officer.

Employ the "plastic wrap method" to test the pavement for moisture as specified in paragraph TESTING FOR MOISTURE.

1.6.1.2 Weather Limitations for Removal of Pavement Markings on Roads and Automotive Parking Areas

Pavement surface must be free of snow, ice, or slush; with a surface temperature of at least 4 degrees C 40 degrees F and rising at the beginning of operations, except those involving shot or sand blasting or grinding. Cease operation during thunderstorms, or during rainfall, except for waterblasting and removal of previously applied chemicals.

Cease waterblasting where surface water accumulation alters the

SECTION 32 17 23 Page 12 effectiveness of material removal.

1.6.2 Traffic Controls

NOTE: Gui dance f or t r af f i c cont r ol pr ocedur es can be obt ai ned f r om t he Manual on Uni f or m Tr af f i c Cont r ol Devi ces ( MUTCD) f or St r eet s and Hi ghways.

Place warning signs conforming to MUTCD near the beginning of the worksite and well ahead of the worksite for alerting approaching traffic from both directions. Place small markers along newly painted lines or freshly placed raised markers to control traffic and prevent damage to newly painted surfaces or displacement of raised pavement markers. Mark painting equipment with large warning signs indicating slow-moving painting equipment in operation.

When traffic must be rerouted or controlled to accomplish the work, provide necessary warning signs, flag persons, and related equipment for the safe passage of vehicles.

1.6.3 Airfield Traffic Control

Coordinate performance of all work in the controlled zones of the airfield with the Contracting Officer and with the [Flight Operations Officer or Airfield Manager] [control tower]. Neither equipment nor personnel can use any portion of the airfield without permission of these officers unless the runway is closed. Runways will be closed during the following times:

Day or Date Runway Closing Time Runway Opening Time Important Notes

1.6.4 Airfield Radio Communication

No personnel or equipment will be allowed in the controlled zones of the airfield 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 provided by the Government. The Contractor is responsible for the radio and must reimburse the Government for repair or replacement of the radio if it is lost, damaged, or destroyed] [is to be provided by the Contractor as approved by the Contracting Officer]. Maintain contact with the control tower at all times during work in vicinity of the airfield.

Notify the control tower when work is completed and all personnel, equipment and materials have been removed from all aircraft operating surfaces.

1.6.5 Airfield Emergency Landing and Takeoff

Emergencies take precedence over all operations. Upon notification from the control tower of an emergency landing or imminent takeoff, stop all operations immediately and evacuate all personnel and equipment to an area not utilized for aircraft traffic which is at least 75 m 250 feet measured perpendicular to and away from the near edge of the runway unless otherwise authorized by the Contracting Officer. Equipment and chemicals

SECTION 32 17 23 Page 13 or detergents as well as excess water must be able to be removed from the work area within 3 minutes.

1.6.6 Lighting

When night operations are necessary, provide all necessary lighting and equipment. [Direct or shade lighting to prevent interference with aircraft, the air traffic control tower, and other base operations.

Provide lighting and related equipment capable of being removed from the runway within 15 minutes of notification of an emergency. Night work must be coordinated with the Flight Operations Manager or Airfield Manager and approved in advance by the Contracting Officer.] The Government reserves the right to accept or reject night work on the day following night activities by the Contractor.
