End-of-shift records for HVAC installation crews
AirOrchestra
The crew talks as usual. The day comes back as the pre-task plan and the daily report, each line traced to the person who said it or the sheet it came from.
Sergei Sysoev
Field software for installation crews and an electrical reference for boat owners, held to one standard: every number sourced, every record traced.
I build software for installation crews, and I’m writing a reference on boat electrical systems. Both rest on hands-on electrical work, from superyacht builds to commercial jobsites.
Book, APLUXOR Marine Electrical Library
Boat Electrical
19 chapters in six parts, every number sourced to ABYC, USCG 33 CFR, ISO or the manufacturer’s manual.
Open-source field calculator
HVAC Pro Calc
Sheet-metal and trade math regression-tested against the published Model 4090 user’s guide; duct sizing by the ASHRAE equal-friction method.
One standard
The three follow the same rules. Measure before deciding. Source every number to a standard or a manufacturer’s manual. Trace every record to the person or the drawing it came from. Test against a published reference, not against my own expectations. And build for the place the work is actually done: a phone in a gloved hand on bad LTE, or a boat owner with a meter in the bilge.
Where it comes from
The standard comes from the field. I’ve worked as an electrician on superyacht builds at Delta Marine Industries in Seattle, a yard that builds custom yachts up to 100 m (about 328 ft). I’ve done electrical and HVAC work on residential homes and large commercial projects, and automotive electrical work. I hold an engineering degree in vehicle fleet operation with a specialization in automotive electrical systems.
