Corridor Baseline Survey
Duration: 2–3 hours on site
Location: South Korea — travel billed beyond 80 km from Gwangju
Scope
A baseline survey answers whether your room can sustain stable airflow corridors before hardware arrives. We map static pressure at intake and exhaust openings, note temperature layers at hashboard height, and document existing obstacles — cable trays, low ceilings, shared walls with living space.
Deliverable
A one-page corridor summary with colour-marked zones: acceptable intake lanes, exhaust lanes that need duct help, and dead zones where no miner should sit. This is narrower than the full placement review and does not include a final rack sketch.
Ideal timing
Empty room before build-out, or existing farm when adding a second aisle without expanding HVAC.
Exclusions
Duct fabrication, fan replacement, and electrical work remain with your contractors. We supply duty-point notes you can hand to an HVAC installer.
