See not below Brian Kurtz, P.E. Kuttz & Associates, lnc. Structural Engineers {970)-945-6305 --- Fon¡varded Message ----- From : Brian Kurtz <kuftzengineer@yahoo.com> To: Aaron Natoniewski <aaronnski@hotmail.com>; Dave Argo <dargo@garfield-county.com> Sent: Wednesday, September 8,2021,05:28:28 AM MDT Subject: Re: BLRE-07-2A-6411 : ADU at 4972 Cty Rd 113 Good morn gentlemen, Thanks for your patience I made a complete review of the foundation design this morn. Dave, I am sure you noticed that our construction documents were issued 4 weeks prior to the soils report issue date. I never make the 'assumptions'when designing for'assumed conditions.' Those assumed soils properties come from the geotechnical engineer. At any rate, after a close look, there are no changes necessary to the foundation design: it is in conformance with the dual bearing properties as recommended by H-P/Kumar in their report no. 20-7-414 (dated A7-28-20).
