How it works

One loop from first call to final hour.

Most shops already have the pieces: a CRM, a planner, Revit, spreadsheets, the shop floor. HALO ARC ties the precon, engineering and shop side together, so the whole story of a job lives in one place and every number can be measured.

01

Design it

Model prefab the way the shop builds it, with a BOM that counts every fitting.

02

Price it

Every bid from intake to award, with vendors, capacity and history behind the number.

03

Build it

Current drawings and the 3D model on any phone. Click anything to see what it is.

04

Prove it

Actual hours against the estimate, by job and work package.

  • Only changed sheets upload again
