Case Study: Nan Inc achieves increased field productivity and avoids costly rework with PlanGrid Build

Nan Inc. uses PlanGrid to improve field productivity and avoid rework

Nan Inc., general contractor on the $80M Kona Judiciary Complex in Kailua‑Kona, Hawaii, faced costly delays and rework from managing projects on paper. Frequent uncertainty about the “latest” plans led to mistakes that required 100–1,000 hours of rework, expensive Hawaii shipping logistics, and daily trips to the trailer to check drawings; previous digital tools proved too hard to set up or use in the field.

Nan piloted PlanGrid with a five‑person core team and quickly adopted its automatic version control, slip‑sheeting, offline access, and hyperlinked drawings. The team saved roughly 2–3 hours per day (about $4,500/week), cut printing costs by thousands ($10,000+ in the first months), and prevented major rework — including a near‑miss that would have cost over $38,000 — improving field productivity and helping the project run ahead of schedule.
