Hello Sir/Madam, I am delighted to participate in your good project. With my previous project involvement on Property Development for Single to Multiple Residential & Commercial Buildings, my passion and proficiency drive me to pursue your objective. With indicated cost, I offer you the following: Milestone 1A. If new Douglas Floor Beams are connected to the Main Resisting Frame, it requires Frame Re-modelling, Section Replacement, Loading Analysis including Gravity, Snow, Wind & Earthquake, Calculation Simulation in series towards optimization. Milestone 1B. If new Douglas Floor Beams are not part of the Main Resisting Frame, it only requires Beams Local Modeling Analysis using Gravity Loading, spacing optimization and Calculation Simulation in Series. Milestone 2. Update of Floor Framing, Update of Beam Connections Details and Execute Connection Checks. I request 2 equal payment terms for each Milestone. As I believe on team success, I wish to request the following from the Client: a.) Existing House CAD file would be great if available b.) Douglas Floor Beams Technical Specs including Strength for comparison with my Wood Section Database to align with Client's market specs. c.) Function of floor area where replacement beams are to be installed. Finally, I envision this project is a typical 2-to-3-Storeys Residence. Please feel free to reach me at Freelancer.com, I am ready to help. Wishing you a great day! Very best. - Hilario Cueva
