What you're looking at
A 150 kW commercial standby generator install — smaller commercial building, new installation, pad-mounted unit on an exterior slab. This demo shows the planning layer a PM builds before mobilizing.
The site plan includes: generator pad placement, ATS location, feeder route in trench, interior EMT run from ATS to the main service, crane path and staging zone, and overhead line clearances.
Planning checks run on every conduit and feeder segment: voltage drop (planning estimate — verify with EOR), conduit fill (NEC Art. 358/362 placeholder — not a compliance determination), and ampacity flag. Each check is a planning prompt , not an engineering output.
Planning packet would include:
• Scope summary + open clarifying questions • Feeder, conduit, and ATS coordination notes • Generator sizing + fuel/runtime planning estimate • Grounding and bonding checklist (licensed electrician must verify) • Material planning list with IFC drawing references • Permit / AHJ / inspection reminders • Crew task sequence and LOTO reminders Static demo — fictional sample location and data.
