Would it be possible to demo all existing barrier roads back to runway transition and regrade for positive drainage? If barrier roads are demo back to runway transition can you guys advise on how many inches we are to raise new installations for positive drainage?

Answer:

The photo and drawing are for reference only. The contractor is responsible for field verification.

The Contractor shall include demolition and reconstruction at the following identified locations

(see attachments/annotated photos):

Failure to address drainage deficiencies within the reconstructed areas shall require correction at no additional cost to the Government.

The identified locations represent minimum required areas for reconstruction. The Contractor shall include sufficient scope in the bid to address all visibly distressed and drainage-deficient areas within these limits.

9. During site walk it was discovered that limits of concrete demo in bid documents do not match existing conditions onsite. More concrete is damaged/cracked/spalling/missing than what is depicted on bid documents drawing scope. Please reference runway specific RFI below. Can the demo limits be expanded/modified in the bid documents? Can scope be changed to demo.

See above.

10. Excel estimate sheet in bid documents states that contractors are responsible to install adequate turn radius for maintenance vehicles.
