Park Dr. Nickerson Engineering <br /> Everett, WA 98203 2221 Everett Avenue, #202 <br /> Everett, WA 98201 <br /> Attn: Marty Steingrebe <br /> NE Project: 19-096 <br /> RE: Damaged Header Review <br /> We visited the residence at the above address to review an existing window header that was apparently <br /> damaged during the installation of a new window. Below is a summary of our observations and the <br /> conclusion of our analysis. <br /> The existing header is a 4x12 over the 10ft window in the dining area. It supports the roof framing over <br /> the dining room and kitchen. The header was damaged in two locations. Near midspan, the bottom of <br /> the header was roughly trimmed reducing the effective depth by approximately 1" (max). The end of the <br /> header(end located towards the living room)was taper cut at the bottom. The taper starts at <br /> approximately 32" from the support, to a 1.75" depth reduction at the support, severely compromising the <br /> bearing capacity of the header. <br /> We performed a structural analysis and have determined the damaged header no longer meets the <br /> building code requirements for strength due to the reduction in the depth near midspan. <br /> Therefore, the existing header is to be replaced with a new 4x12 DF#1 or better. <br /> We trust this addresses your concerns. Please feel free to contact us via phone if further clarification is <br /> required. <br /> Sincerely, <br /> Nickerson Engineering <br /> A Li <br /> •''< 'WAS�j7�� 10 <br /> ' f ti <br /> VP <br /> .� <br /> iOPar4s., <br /> //3 <br /> Nickerson Engineering •2221 Everett Avenue, #202 Everett, WA 98201 • (425) 610-4425 <br />
