S3DA Design provided a seamless integration of structural stability and modern MEP systems to transform a functional garage into a high-quality living space.&nbsp;<\/p>\n\n\n\n<p><strong>S3DA\u2019s Scope:<\/strong>&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Structural Engineering:<\/strong>\u00a0Comprehensive gravity, wind, and seismic load analysis per 2022 CBC and ASCE 7; design of foundation systems, garage-level framing, floor diaphragms, shear walls, and a complete permit-ready calculation package.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Mechanical (HVAC):<\/strong>\u00a0Detailed heat load reports, mechanical floor and roof plans, and refrigeration\/condensate piping design.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Electrical:<\/strong>\u00a0Full lighting and power floor plans, single-line diagrams (SLD), and panel schedules tailored for residential efficiency.\u00a0<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Plumbing:<\/strong>\u00a0Domestic water and sanitary drainage systems, natural gas floor plans with isometric riser diagrams, and specialized roof rainwater design.\u00a0<\/li>\n<\/ul>\n\n\n\n<p><strong>Key Challenges &amp; Solutions:<\/strong>&nbsp;The primary engineering challenge was the vertical integration of a residential living space over an existing functional footprint. S3DA\u2019s structural team engineered a robust framing system to support the second-floor ADU while&nbsp;maintaining&nbsp;the open spans required for the garage below. By acting as a&nbsp;Single Source of Responsibility, we&nbsp;eliminated&nbsp;the common coordination gaps between MEP and Structural teams, ensuring that plumbing risers and mechanical ducting were perfectly harmonized with the structural shear walls and floor joists.&nbsp;<\/p>\n\n\n\n<p><strong>The Result:<\/strong>&nbsp;S3DA delivered a fully coordinated, permit-ready set of drawings and calculations that strictly adhered to San Diego\u2019s local building codes. The result is a value-engineered, energy-efficient ADU that maximizes property utility while ensuring long-term structural integrity and occupant comfort.&nbsp;<\/p>\n","protected":false},"featured_media":4961,"template":"","projectscategories":[466],"class_list":["post-9342","portfolio","type-portfolio","status-publish","has-post-thumbnail","hentry","projectscategories-adus"],"acf":[],"_links":{"self":[{"href":"http:\/\/65.21.7.236\/s3da-design\/wp-json\/wp\/v2\/portfolio\/9342","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/65.21.7.236\/s3da-design\/wp-json\/wp\/v2\/portfolio"}],"about":[{"href":"http:\/\/65.21.7.236\/s3da-design\/wp-json\/wp\/v2\/types\/portfolio"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/65.21.7.236\/s3da-design\/wp-json\/wp\/v2\/media\/4961"}],"wp:attachment":[{"href":"http:\/\/65.21.7.236\/s3da-design\/wp-json\/wp\/v2\/media?parent=9342"}],"wp:term":[{"taxonomy":"projectscategories","embeddable":true,"href":"http:\/\/65.21.7.236\/s3da-design\/wp-json\/wp\/v2\/projectscategories?post=9342"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
