Date: January 27, 2025 To: Wallace Architecture, PLLC 311 Third St. Excelsior, MN 55331 Attn: Dan Wallace, Architect From: Eric Bunkers Project: Garrett Residence 650 N. Brown Rd. Long Lake, MN 55356 Proj. No: 25009 Subject: Proposed Remodeling Dear Dan: Bunkers & Associates LLC structural engineers 6687 Forest Street Farmington, MN 55024 651.366.2853 As requested, we designed new structural members for the above referenced project. We have designed the new members using a roof and floor dead load of 15 psf, a roof snow load of 35 psf, a floor live load of 40 psf and a 115 mph Ultimate Design wind speed in accordance with the Minnesota State Building Code. Wind shear walls have been designed using IRC R301.1.3. Our work only includes designing the new members as shown at the above reference project and is based on drawings provided by you and from our conversations. We reviewed structural sheets 04, 06 and 08 based on annotated framing and foundation notes we previously sent showing the new members and connections. All framing and foundations shall be shored and temporarily braced as required by the contractor and all minimum nailing shall be in accordance with IRC Table R602.3(1). Lumber shall be minimum #2 SPF with treated lumber to be #2 S. Pine and engineered lumber to have Fb = 2850 psi with E = 2.0. Our calculations assume all lumber is of good quality and does not have large splits and checks and shall be visually inspected by the contractor at the time of construction. All fasteners in contact with treated lumber shall be G185 hot dipped galvanized or equal. Rebar shall be grade 60. Concrete used for footings shall have a 28 day compressive strength of 5000 psi. The new footings have been designed as typical spread footings based on a presumptive load -bearing value of 2000 psf in accordance with Table R401.4.1 of the IRC. Presumptive soil bearing value shall be verified by a geotechnical engineer where required by the building official per R401.4. The existing footings have been assumed to be typical spread footings on good soils that are assumed to be performing adequately. The contractor shall also verify the condition of structural members and foundations affected by the remodeling. Exterior grade shall slope away from the building and gutters with long downspouts should be used whenever possible. New finish cracks in existing walls and ceilings are likely and common in remodel construction. When installed as indicated above, the new framing members and new foundation shown on the reviewed sheets shall support the loads as required in accordance with the Minnesota State Building Code. If you have any questions or concerns, please feel free to contact us. Sincerely, Bunkers and Associates, LLC Eric M. Bunkers, P.E. MN Reg.
