Hello, I am a licensed Structural PE with over 20 years of experience in residential wood framing, load-bearing wall modifications, beam/header design, and permit-ready calculations. I can evaluate the proposed 80" × 36" doorway opening and provide a safe structural design that maintains the load path through the existing wall. My scope will include: • Review of existing wall and framing conditions • Determination of tributary roof/floor loads • Header or beam sizing • Jack stud and king stud requirements • Bearing and connection checks • Deflection, shear, and bending calculations • Temporary shoring recommendations • Code-compliant structural notes/details • Signed calculations or permit drawing if required I will focus on an economical solution using standard or engineered lumber as appropriate. Please provide the project location, wall photos, floor/roof framing direction, number of stories above, and any existing plans.

Hi, I can prepare the structural calculations required to safely create the new 36" wide × 80" high doorway in your existing wood load-bearing wall. As a licensed structural engineer, I will evaluate the loads currently supported by the wall and design the new header and supporting framing accordingly. Deliverables will include: • Existing load-path assessment • Dead, live, roof, and snow loads as applicable • Header sizing and material specification • Stud-pack and bearing design • Connection and fastening requirements • Deflection and strength verification • Temporary support/shoring notes • Permit-ready structural calculations If foundation or beam support below the new opening must also be checked, I can include that in the analysis. I have completed many similar residential wall-opening and remodeling projects and understand the importance of keeping the field solution simple and buildable. What city is the project located in?

Hello, Your doorway modification is a straightforward structural project, but the header must be designed based on the actual loads above rather than simply selected from a generic span table. I am a licensed Structural PE and can provide: • Review of existing wall construction • Identification of supported floor/roof framing • Tributary load calculations • Header beam design • Jack/king stud sizing • Bearing and compression checks • Fastener and connection details • Local code compliance review • Structural calculation package for permitting I have extensive experience with wood-framed homes, wall removals, new openings, LVL headers, dimensional lumber, and renovation engineering. The final design will clearly identify the required header size, number of plies, support conditions, and construction notes so your contractor can complete the work safely. Please send photographs and the framing dimensions above the proposed doorway.

Hi there, I’m a licensed Structural Engineer with 10+ years of experience designing and analyzing wood-framed residential structures and load-bearing wall modifications. I can evaluate the existing wall, determine the loads carried above the proposed 80" × 36" opening, and design the appropriate header, jack/stud configuration, and load path. I’ll prepare clear structural calculations and construction details addressing gravity loads, connections, bearing, and applicable local building-code requirements. . I can also review the existing framing and provide practical recommendations for temporary shoring and construction sequencing where necessary. My goal is to provide a safe, code-compliant, permit-ready solution that your contractor can confidently build. Thanks, Wendell
