# Mythic Engineering — johnbrindley.com > Licensed engineering for owners building large and custom homes in light-gauge steel (LGS), focused on Gulf Coast hurricane zones and the southern US. Engineering first, then LGS. The owner keeps a shoppable package (stamped drawings sealed by a licensed PE in their state + documented wind/load basis) and can take it to any fabricator or general contractor. Site map: `/` is John Brindley's personal page (background, companies, offerings). The interactive fee-range quote tool lives at https://johnbrindley.com/quote (old links to `/` with query strings, and `/JB/quote`, redirect there). The JSON API below is unchanged. Software can draw it. A licensed engineer has to stand behind it. ## Services - LGS structural design and stamping (core) - MEP engineering (supporting service) ## Rate card (estimates; a fixed fee comes by proposal) - Structural, inland South: $2.25/sf - Structural, Gulf & Atlantic hurricane-coast counties: $2.75/sf - Structural, beachfront / coastal high-hazard lots: $3.25/sf - Complexity add-on (3+ stories, on piles, long spans/cantilevers, large glazing walls): +$0.50/sf - MEP: +$2.25/sf - No line prices below $2.00/sf. Minimum fee $2,500 ($1,250 ADU/tiny house). - Projects over $25,000 receive a custom proposal from John Brindley. ## Agent access - GET /api/estimate?sqft=4000&zip=36561&scope=structural|mep&complex=true|false&tier=inland|coastal|beachfront&type=house|adu - Returns a price RANGE (JSON), never line items. Rate-limited per IP. No email is sent, no account needed. - Itemized estimate (coming soon): requires verified identity via Continue with Google, or by emailing your one-time code from your own address to quote@mythiceng.com. ## Contact Send us your model or estimate. ## Steel framing budget range (in /api/estimate) The estimate response includes `building`: {label, range_low, range_high, includes_install, delivery_miles_assumed, price_movers[], firm_pricing, note}. Optional params: `install=true|false` (full-shell install labor, default true), `miles=` (default 150), `complex=true|false`, `tier=inland|coastal|beachfront`. Budget estimate, not a bid: LGS framing package fabricated and delivered, plus optional install. Excludes foundation, finishes, MEP install, and site work. Firm pricing comes from the fabricator you choose; this range is your budget benchmark. Steel weight inputs (optional; defaults inferred from lot tier: inland 115 mph / B, Gulf coast 150 mph / C, beachfront 160 mph / D): `stories=1..4+`, `wind_mph=`, `exposure=B|C|D`, `design=standard|modern`, `seismic_sdc=A|B|C|D`. The response shows `steel_lb_per_sf` and `weight_assumptions` so you can correct any assumption and re-query.
