Proposed Kitchen Remodel and Patio Cover

Project Details

This project involves the structural design and engineering for a residential kitchen remodel and the addition of multiple patio cover framing systems. The comprehensive scope required modern engineering solutions for the entire structural assembly, including the analysis and design of timber floor joists, roof rafters, wall headers, and high-capacity glulam beams. The primary structure utilizes high-strength Douglas Fir-Larch lumber (No. 1 and No. 2 grades) and 24F-V4 glulam floor beams, integrated with specialized Simpson Strong-Tie connectors and A325 through-bolts to ensure a durable and stable assembly. The design process included a rigorous structural analysis to ensure the modified structure and new additions could safely withstand all applicable environmental loads. The structural elements were engineered in accordance with the International Building Code (IBC 2024), the California Building Code 2025, and ASCE 7-22 provisions. Special attention was given to lateral load resistance and skewed connections, providing stability against design wind speeds of 96 MPH and meeting the stringent requirements for Seismic Design Category D. The foundation system features a combination of independent reinforced concrete pad footings (up to 3’x3′) and 20-inch diameter drilled pier footings, all designed to perform reliably under an allowable soil bearing capacity of 1,500 psf.

Role

Structural Engineer/Designer

Services Provided

The scope of services included the preparation of structural analysis, structural calculations, and structural drawings for the proposed kitchen remodel and patio cover (pergola) connections. The work involved evaluating the removal of existing kitchen walls to determine load-bearing conditions, designing the required beams and headers for new openings, and verifying the structural adequacy of the three proposed pergola connection points to the existing structure. The services also included anchorage and load transfer analyses to ensure a continuous and code-compliant load path to the primary structure. Structural plans and details were prepared to identify required framing modifications, beam and post layouts, connection and anchorage requirements, typical framing sections, and structural notes suitable for permit review and approval.
