7. Question: Is there any fire rating requirement for the EPS insulation? Provide ASTM specification & density requirement for this material.

Answer: 4’-0”/1220 mm is the correct dimension.

15. Question: Confirm height of protection Type C, on the elevations they appear to be the same height as Type D.

Answer: 1220 mm is the dimension to use.

16. Question: Can you provide the heights required for protection Type E at the columns where the protection is shown partial height?

Answer: The height of Type E protection is intended to be at least 18 inches above the height of adjacent equipment/construction being removed. The minimum height shall be 8’-0”.

17. Question: Demolition options 4 & 5 and 6 & 7 have areas of overlap both of which appear to include removal of the same walls. How are we to account for this in our option pricing?

Answer: These areas do not overlap. The limits of the option areas are defined by the structural walls that outline these areas. For example, the NW court’s four walls are on column lines 6, 11, K and F. Price the side of the wall facing the space. The pricing for the opposite face of the wall is to be included in the adjacent area/option.
