Frank,

 

I have attached all of the information on the subgrade preparation for Exechangar.  How do you advise that I respond to Mr. John Johnston?

 

Thanks,

	John,

	 

	What FAA Advisory Circular was used for the pavement design?

	Clay,
	
	Attached is the soils engineer's latest recommendations for the paving for our project.
	
	I realize you will need to forward this on to your third party consultant for their review. Any expedition you can offer in that regard would be most appreciated.
	
	We have Terracon conducting density testing on the paving and tomorrow I'll be scheduling an inspection with Dave Wilde to verify the concrete encasement of the 2 culverts in the north
approach as well as grade point checks on the same approach.
	
	Please let me know if there's anything further you may require.
	
	Regards,

		Dan -

	 

	Attached is a letter about subgrade preparation. I trust this approach will be acceptable to the City and to the FAA.  We feel comfortable with it.

	 

	Thanks,
