120 Degreez Engineering in downtown San Diego's Gaslamp Quarter has provided mechanical, electrical, and plumbing engineering from its Broadway office since the firm's 2013 founding. The firm's Title 24 energy-compliance modeling and CalGreen documentation integrate with architectural BIM coordination sets at Gensler, where MEP clash detection runs against structural models before entitlement submittals reach the city. Engineers on staff hold active PE licenses across more than 40 states, enabling 120 Degreez to stamp mechanical, electrical, and plumbing documents for federal and municipal projects well beyond California. Each design package runs through Revit-based building information modeling with automated conflict flagging between ductwork routing, conduit paths, and waste lines before construction documents leave the office. The electrical panel schedules and load calculations from that environment ship as bid-ready construction documents precise enough for a C-10 holder such as All City Electric, Inc. in Bankers Hill to price and permit without a preliminary site visit. The firm's most complex engagements involve simultaneous HVAC sizing, plumbing riser design, and full power-distribution engineering for multistory mixed-use structures requiring Title 24, CalGreen, and San Diego fire-code sign-off on a single permit set.
