Questions Answers

1 This project appears to be an ideal candidate for Cold In-place Recycling rather than pulverize in-place and overlay, and the use of Cold In-place Recycling may result in significant cost savings for the FHWA. Has the FHWA considered this alternative and if not, whom can be contacted to inquire about a possible value-engineering opportunity

See FAR 52.248-3 and FP-03 Subsection 103.03 regarding value engineering change proposals.

2 Are there profiles or elevations for the existing drainage systems to be removed or new drainage systems to be installed? If not, can these be provided? It is difficult to accurately price this work without knowing the drainage culvert inverts or depths.

See culvert cross sections posted with Amendment 001.

Stump removal is not required for trees felled and/or removed under Option Z. Amendment 002 revises Subsection 202.07 to clarify this requirement.

8 Section 202.07 of the Special Contract Requirements states “Fence the drip lines of trees and plants remaining in or near the construction zone using construction fence.” Is this necessary?

Amendment 002 deletes this requirement
