Mr. Zhang,

 

I was good speaking to you a few minutes ago. Per our discussion, please proceed with getting the following items are accomplished/answered for our bridge design at Vitruvian Park in
Addison:

·         Global stability analysis of abutments at Ponte, Bella, and the Southern Pedestrian Bridge (as required)

·         Clarification of the 110 pcf lateral load for retaining walls

o        Is this an at-rest load for on-site clays (as is assumed)?

o        Can this be reduced by using select fill or a granular fill?

 

I understand that the cost of this stability analysis is approx $2,800. Please consider this email as your authorization to proceed. Because of our limited amount of time, I ask that
you proceed with all due haste and I also ask that you provide Halff with any and all information they require from you to complete their design work.

 

Please feel free to contact me if you have any questions or concerns.

 

Thanks,

 

Eric Little
