Skyway Drive, Windsor, CO Crown Engineering, llc. Project No. 53-01-29-06 Gentlemen: As requested, we have reviewed the use of MST27 Straps to be used as hold-downs in place of the STHD 14 hold-downs on the front wall of the garage. It is our opinion that the MST27 straps attached to the outside face of the foundation and nailed up along the framing should be an adequate substitution for the hold-downs at the front wall of the garage. Additionally, the required four hold-downs were increased to a total of six hold-down straps along the front wall of the garage. We also reviewed the front porch post sizes, post to foundation and post to roof beam connections. It is our opinion that the 4x4 posts used are adequate for the support of the imposed design loads at that location. Additionally, the use of a Simpson AB44 for the post base and a Simpson AC4Z coupled with an H2.5A hurricane clip for the post to beam connection are deemend adequate substitutions. Thank you for consulting with us on this phase of your project. If you have any questions, please do not hesitate to contact me at (970) 691-4239.
