Answer: The FAA is looking at an August through September start date that can be determined after the contract award.

2. Question: What is happening with the road to the glide slope shelter?

Answer: Further details are being provided in a forthcoming amendment

3. Question: Are we removing the existing paved road and replacing it with gravel.

Answer: The existing paved road from the runway to the glide slope facility should be removed and disposed of offsite. The existing pavement is approximately 4” thick.
