Accurate BOQs in minutes, not a measuring weekend.
Read PDF, CAD and BIM drawings automatically. Extract HVAC quantities, generate bills of quantities, and catch design changes between revisions.
The pain
What is leaking today
Fabrication is tribal
Who cut what, when — in someone’s head.
Install vs drawing
Rework because the floor did not see the change.
QA is a signature
Not a photo, not a check.
How Spark solves it
The system, not another tool
Job packets
Cut lists and drawings that travel.
Floor status
What is in fab, what is on site.
QA with evidence
Checks and photos on the job.
