GDL Consultancy
Software for construction, built by people who’ve done it.
Tools designed by surveyors, engineers, and tradespeople who know why the takeoff matters and what the BoM has to defend.
What GDL does
GDL Consultancy builds software for the construction industry — tools that are quick to pick up, easy to use, and built by people who’ve done the work.
Featured product
MarkMetric
A browser-based PDF takeoff tool for construction estimators. Three things make it different:
-
Multi-drawing.
Quantities reconcile across the whole drawing set, not one sheet at a time.
-
Multi-scale.
Site plan at 1:500, detail at 1:20 — no need to split the file.
-
Supplier-aware price lists.
Per supplier, per project, per client. BoMs that price themselves correctly.
What’s next
MarkMetric is the first GDL product. We’re already mapping the next ones — same brief, different problems. If there’s a corner of construction where the software hasn’t caught up with the work, we’re probably interested.
