GOVERNMENT RESPONSE: GRAPHICAL ERROR. SHOULD HAVE BEEN AN LOD LINETYPE TO

INDICATE WORK NOT NEEDED IN THIS AREA.

16. On Sheet CS101, what type of paving is the 20-foot-wide driveway to the tower?

GOVERNMENT RESPONSE: THIS AREA SHOULD BE HEAVY DUTY ASPHALT. NOTE THAT THE

DETAILS TITLES FOR LIGHT DUTY AND HEAVY DUTY WERE INADVERTANTLY SWITCHED. SEE

ADDENDUM #1 SHEETS CS101 AND CS501 TO CLARIFY THE PAVEMENT SECTION AND

CORRECT THE DETAIL TITLES.

17. On Sheet CS501, where is detail B1/CS501 used?

GOVERNMENT RESPONSE: THE MOW STRIP DETAIL SHOWN ON CS501 IS SHOWN AS A HATCH

IN THE LEGEND ON CS101 AND ALONG THE NW AND SE CORNERS OF THE BUILDING. THE 3'

If epoxy coated reinforcing is needed, please clarify where it is to be used, for instance should it be used in the exterior concrete walls of the tower per drawing S-101?

GOVERNMENT RESPONSE: EPOXY COATED REINFORCING IS NOT REQUIRED IN THIS

PROJECT.

21. Section 05 12 00, Paragraph 2.6.2 Shop Primer.

Specification 05 12 00-2.6.2 Shop Primer notes SSPC Paint 20 or SSPC Paint 29, (Zinc Rich Primer) for steel.

29. Section 01 35 13 – Special Project Requirements, Paragraph 3.1.2 – Schedule of Work/Aircraft Operating Schedules.

Paragraph 3.1.2 notes that the Government will exert every effort to schedule aircraft operations so as to permit maximum amount of time for contractor’s activities.

Please confirm if the contractor must cease operations as a result of aircraft operations per this paragraph, this event will be considered a differing site condition and will be treated as a compensable time for any delays per the FAR.

GOVERNMENT RESPONSE: CONFIRMED

30. Section 01 45 00.00 20 – Quality Control, Paragraph 1.5.4 – Alternate QC Manager Duties and Qualifications.

31. Specification 07 81 00, Paragraph 1.3.2

Specification section 07 81 00 “Spray Applied Fireproofing” – fire rating schedule states that floor decks and floor supports are to be two-hour fire rated.

Additionally, none of the floor decks in the structural drawing nor architectural drawings show applied fireproofing to the floor decks.
