The project moves. The margin shouldn’t bleed.
Whetstone embeds senior operators inside contractors, engineering and AEC firms to control change orders, protect cash flow, and keep projects on schedule and budget — so thin margins survive contact with the field. Business-side only: we never touch engineering sign-off or site safety.
Where construction margin bleeds on the job.
Thin margins die by a thousand cuts — overruns, missed change orders, trapped cash. We find the operational wounds and close them.
