I’m adding an extension to my single-family wooden home and already have a complete set of architectural drawings ready. What I now require is a licensed structural engineer who can prepare the full set of design calculations that will satisfy local building‐code review and allow my contractor to proceed without delays. You’ll be working directly from the existing plans, so no re-drafting is needed—just the structural analysis, load calculations, and any supporting notes or schematics that demonstrate code compliance for wood framing, connections, lateral resistance, and foundation tie-ins between the new and existing portions of the house. Deliverables: • A stamped calculation package (PDF) that the municipality will accept • Any supplemental sketches or mark-ups necessary to clarify beam, joist, or post sizes and connection details Please let me know your turnaround time, the software you’ll use (e.g., SAP2000, RISA, or similar), and any questions you have about the current plans so we can get started right away.

Hi, This is Maksim. I have carefully reviewed your job description and fully understand that you require a comprehensive structural calculation package and connection schematics to get your residential wooden home extension approved without delays. With 10 years of experience in structural design, CAD drafting, and preparing fabrication-ready construction packages, I specialize in analyzing wood framing networks, calculating lateral wind/seismic resistance, and designing secure foundation tie-ins between existing and new structures. I can work directly from your architectural plans to deliver a highly detailed, code-compliant analysis covering all beam, joist, and post sizing, as well as the critical connection details local building departments scrutinize. For this project, I will utilize RISA-3D and specialized wood calculation software alongside AutoCAD for clear, supplemental mark-ups to ensure your contractor has exact shop-floor clarity. To tailor the calculation package precisely to your local municipal guidelines and provide an accurate turnaround time, I would just need to confirm the specific city and state your project is located in so I can account for regional snow, wind, and seismic loads. I am ready to begin immediately upon receiving your architectural set. Best Regards

Would you like the stamped calculations to follow a specific local code edition or jurisdiction formatting, and are there any existing geotechnical reports or known foundation issues I should account for? Also, are you expecting full structural drawings or only calculations and sketch mark-ups for the contractor? Hi — I’m Mohand, a U.S.-based, structural engineer with extensive experience in wood-framed residential additions and roof truss reinforcement. I’ve completed numerous municipal plan-check submittals, so I understand what reviewers require for a smooth approval process and minimal RFIs. For your project I will perform a full structural analysis and load calculations for the new roof, framing, connections, lateral resistance, and foundation tie-ins to the existing structure. Deliverables will include a stamped calculation package in PDF that your municipality will accept plus clear supplemental sketches or mark-ups clarifying beam, joist, post sizes, and connection details. I typically use RISA and SAP2000 for analytical modeling and verify results with hand calculations where needed to ensure robustness

Hello, I work on residential wood-frame structural analysis and permit documentation, including extension/addition projects requiring code-compliant calculation packages for municipal approval. Since your architectural drawings are already complete, I can focus directly on the structural scope—load paths, framing analysis, connection detailing, and integration between the existing structure and new extension. The deliverables can include: • Structural calculations for beams, joists, posts, headers, and lateral systems • Foundation tie-in and load-transfer analysis between existing and new framing • Connection and fastening verification for code compliance • Supplemental sketches/markups clarifying member sizing and structural details • Permit-ready stamped PDF package coordinated for contractor execution I typically work with RISA, SAP2000, and standard wood design/code references depending on jurisdiction requirements and project complexity.

Hello, I have experience preparing structural calculation packages for single-family wood-framed additions, including gravity loads, lateral resistance, beam and joist checks, post sizing, connections, and foundation tie-ins. I am interested in this project because the architectural drawings are already complete, and the main need is a focused structural review package that can satisfy code review and help the contractor move forward. I will review the architectural plans, analyze the new extension and existing connection points, calculate roof, floor, wall, lateral, and foundation loads, prepare supporting sketches or mark-ups for framing and connection details, and coordinate the final stamped PDF calculation package through a licensed structural engineer. I can use tools such as RISA, Enercalc, Forte, SAP2000, or similar software depending on the framing system and local code requirements. Thanks for reading my proposal. Edwin
