I’m expanding my home in Brownsville, TX and already have Plans & Specs in PDF only (not DWG). What I need is full structural calculations for the addition so the city will issue a permit and my contractor can proceed. Scope • Perform all required structural calculations and analysis for the planned addition, accounting for local wind loads, soil conditions, and the latest IRC/IBC requirements. • Reference my existing drawings throughout the work to ensure seamless tie-ins between old and new construction. • Deliver a clear, professionally formatted report (PDF) that the building department can review without further clarification. Native calculation files (e.g., Excel, ETABS, SAP2000, RISA, or similar) should accompany the final PDF. Acceptance The job is complete when I have: 1. A signed calculation package that demonstrates code compliance for gravity, wind and lateral loading. 2. A brief summary sheet my contractor can post on-site. 3. All supporting model or spreadsheet files. 4. An approved building permit. If you are familiar with Texas residential codes and comfortable working directly from existing PDFs, you’ll be able to move quickly on this. Call me and I can supply the plans for your bid and will respond promptly to any clarification you need. See pages 8 + 9 for dimensions. Attached are pages 1 - 5. I can e-mail pages 6 - 9 when you call, or go to google drive: We are currently taking bids for this job. Disregard those fill in the blanks below that relates to our budget.

This is Mohand, a U.S.-based structural engineer with extensive experience preparing residential addition calculation packages for Texas jurisdictions. I will perform all required gravity, wind, and lateral analyses per the latest IRC/IBC and applicable ASCE wind provisions for Brownsville, and I’m comfortable working directly from PDF plans.

My background includes multiple successful residential permits in Texas and coordination with contractors to ensure constructible solutions.

Hello, I have experience preparing structural calculation packages for residential additions, including gravity loads, wind/lateral analysis, foundation checks, framing members, and tie-ins to existing construction. I am interested in this project because Brownsville requires careful attention to local wind conditions, code compliance, and clear documentation that the city and contractor can use without confusion. I will review the PDF plans, including pages 8 and 9 for dimensions, then prepare signed structural calculations for the addition based on IRC/IBC requirements, local wind loads, soil assumptions, and the proposed connection between the existing home and new work. I will deliver a professional PDF calculation report, a contractor summary sheet, and supporting Excel/RISA/ETABS/SAP2000 files, and I can help respond to permit review comments if needed. Thanks for reading my proposal. Edwin
