Addendum 3

• What type of paint and beads are required for this project? Specific type of each will allow all bids to be accurate and competitive.

Paint Color Specifications, Requirements for Surface Preparation, Paint Application Rates and Methods, and Requirements for Preformed Thermal Plastic Markings. AC 150/5370-10 provides the paint color specifications, requirements for surface preparation, paint application rates, the various methods for applying paint, and the performance requirements for using preformed thermoplastic markings.

• Are you looking for surface prep to be accomplished by waterblasting? If so, will the blaster be allowed to prep all areas prior and have the painting crew to follow for full access to the markings?

Method of removal/ preparation is up to the contractor as long as it meets the requirements of preparation as outlined in 150/5370-10H.

It is preferred to do it in sections to avoid prolonged periods of missing markings however, the airport has flexibility and will allow larger sections of centerline to be done concurrently. Hold position markings shall not be left unmarked overnight.

• When referencing the "hold position markings" in the SOW, is the request to price the Hold Short-lines or the Holding Position Sign (red w/ white numbers)? Or is the request for bidding areas referencing both short-lines AND position signs?

As written, the bid is for “Runway Holding Position Marking” and not “Surface Painted Holding Position Signs”

• Are any of the markings required new, or all restripe?

All painting is over existing markings. No new layout required.

• When were the existing markings last painted?

Exact date is unknown, but they are believed approximately 5-7 years old

• Will there be a staging area provided for the contractor? If so, is it within the secured airfield area?

A staging area is available inside the Secured Area of the airfield.

• Is water available on site?

Yes. Water is available nearby.

• Any restrictions on work hours- specifically at night?

Night work is acceptable to the airport.

Waterborne. Paint shall meet the requirements of Federal Specification TT-P-1952F, [ Type I ] [ Type II ] [ Type III ]. The nonvolatile portion of the vehicle for all paint types shall be composed of a 100% acrylic polymer as determined by infrared spectral analysis. [ The acrylic resin used for Type III shall be 100% cross linking acrylic as evidenced by infrared peaks at wavelengths 1568, 1624, and 1672 cm-l with intensities equal to those produced by an acrylic resin known to be 100% cross linking. ]
