Ron,
Below is the email I sent to the engineer for Million Air yesterday. It does include a solution for the jointing issues.
By the way, I do remember meeting Mr. Ron Fredrick at a DRC meeting on June 8. We informed him (as we do all developers on the airport) that we would waive the third party engineering
review if he hired one of the following engineering companies:
1. Garver Engineers
2. HNTB, Corp
3. KSA Engineers, Inc.
4. Freese & Nichols
5. DMJM Aviation
Although probably more costly than hiring another engineering company, these engineering companies have extensive experience with airports and the top three have extensive experience
on Addison Airport. I know that Mr. Fredrick has been critical of the time taken to conduct a third party review. Hiring one of these companies would have insured that the FAA standards
had been followed making a third party review unnecessary. I just wanted to let you know that we did extend an offer to eliminate the third party review under these circumstances.
I will continue to work with the engineer to complete the drawings as quickly as possible and will keep you informed of our progress. If you have any questions, please let me know.
Thanks,
Clay Barnett, P.E.

Subject: Million Air Jointing Plan
Lynn,
The Town of Addison has reviewed the attached jointing plan and takes no exception to the dowel bars being limited to the areas indicated. However in a meeting with the developer and
his architect this morning, they have expressed interest in paving the area out to the taxiway. In this instance the dowel bars would be required along the taxiway.
On another note, the joint plan as laid out appears to be a Jointed Reinforced Concrete Pavement (JRCP). There is a design method that should be used to determine the reinforcing size,
spacing and joint spacing all of which are interrelated (i.e. the amount of steel affects the joint spacing and vice versa). Submit the JRCP design in accordance with the FAA Circulars
with the next submittal. Alternatively, specify that the reinforcing steel it to be cut 3" from either side of each sawcut joint. Under the alternative method the concrete is no longer
continually reinforced and the JRCP design procedure is not necessary.
If you have any additional questions, please let me know.
Thanks,
Clay Barnett, P.E.

Todd,
Attached is a copy of the ramp jointing plan with clouds shown where I believe the doweled joints should be located. As I mentioned, the other edges will not have the loading on them
since the aircraft only park in these areas and the weight of the aircraft does not get close to the edges.
Please review and let me know what you think.
