Box 1758 365 West 50 North, Suite W-1 Vernal, Utah 84078 Grand Junction, CO 81505 Dear Shawn, Subject: Juhl Foundation -1761 CR 117, Glenwood Springs, CO I am writing in regards to the foundation of the Juhl residence at 1761 County Road, 117 near Glenwood Springs, Colorado. In a telephone conversation with you earlier this month, I stated that a 3-ply 2x12 header may be used to support the basement marriage line beam over a 4-foot basement window opening. This header should be supported at each end by no less than a 1-ply 2x6 jack stud with a 1-ply 2x6 king stud. Sizing calculations for the header and supports are included with this letter.
