Michael Boone email: boonerealtymn@gmail.com 7144 River Terrace NE, Fridley, MN This plan shall be printed and be job site for inspections. Re: REPORT ADDENDUM 7144 River Terrace NE, Fridley, MN Dear Michael Boone; This report is based on subsequent engineering evaluation requested by the Client following our original report dated June 21, 2022. Items include: 1. An additional option for a shorter span in the living room that would result in a wood flush beam that does not extend below the existing ceiling. 2. Provisions for a an option in the kitchen that results second and parallel beam in the kitchen area 16" apart. 3. An additional option for a 3-ply beam at the exterior wall. 4. An additional option for two spans of 8'( vs a 16' span) at the exterior wall. Addendum Items are indicated in RED below: On Tuesday, June 711, 2022, an engineer from Complete Building Solutions (CBS) was onsite. During our inspection we took pictures and measurements to record our findings. Our assessment and analysis are summarized below. A non-intrusive investigation was performed, as many of the structural members were hidden, some assumptions based on traditional construction methods and visible members were taken. All measurements provided are the max allowable length/height (due to construction renovation variables that occur) and exact member measurements shall be field verified. Please hire a qualified contractor to perform the work. CBS recommends the homeowner has the contractor apply for a building permit prior to construction. Each city has unique site setbacks and requirements for building permits that may require modifications to plans. Background Summary: CBS was contacted to evaluate proposed wall removals in the home: • Living Room Wall. The living room wall designs include evaluation of the existing rear window header capacity where the new beam will bear. The evaluation concluded that an additional post must be provided at the window header.

This should be a stud wall installed on both sides the beam to be T replaced within 18" to 24" proximity of the existing wall from floor to ceiling. Once temporary 0 3 support is in place, the existing beam and posts can be removed, and the new header beam £ installed. Some ceiling distress can be expected. cu The installation for this beam/header/post frame involves: 1. Install the posts. Provide a solid section of wood from foundation elements (foundation wall, basement slab, or other as described) to the bottom of the new beam. When crossing T o a floor, ensure that blocking (small wood posts the same size as the posts) are installed o between the underlying joists and the subfloor above. cu2. Do not remove any existing posts near the ends of the new beam unless explicitly identified o as "replacement". 3. Install the beam, with the beam resting on the post tops. Toenailing is adequate in most cases. Post tops and bottoms can be attached using Simpson Strong Tie Framing Ange A34 or approved equivalent. IL 11 4. If you cut pressure-treated wood, reseal the cut end of the wood with a preservative vtreatment: m • Outdoor: copper naphthenate or oxine copper, example: "Outlast Q8 Log Oil" • Indoor: borates, example: "Bora-Care" If you have any questions, please feel free to contact Complete Building Solutions at admin@cbsmn.com to schedule additional time.
