“We only spend around 1–2 hours doing take-offs with Ensign — before it used to take 5 or 6 hours… The speed on complicated tenders is amazing, and the repeat key for duplication of branches is a lifesaver. Support’s great, even out of hours.”
AG Vent’s estimators were stuck in a manual workflow — printing drawings, scaling by hand, then re-keying numbers into spreadsheets. Complex branch runs (dampers, doors, bends, reducers, offsets, flex, grilles) turned every package into a time sink, and consistency was hard to police across multiple estimators. Result: long evenings to hit tender deadlines and less time on live jobs.
AG Vent moved to Ensign Ductwork Take-off & Estimating with a DW144, TR19 specification and assembly-first setup. Estimators trace mains and branches once, and Ensign expands them into fittings and ancillaries to spec, including bends, reducers, tees, transitions, access doors, turning vanes, flange kits and sealants.
Supports and hangers are generated automatically to your rules, with spacing and type driven by run length, size and system requirements, ensuring costs are consistent across the take-off. Complex risers and mirrored branches are cloned in seconds with full audit trails, while one click pushes the take-off to Estimating, producing labour-timed pricing and UK-curated rates for a clean SoR and client-ready tender without re-keying.
When deadlines bite, Ensign’s UK-based support team provides fast, knowledgeable help to keep projects moving.
Typical ductwork take-offs that once took 5–6 hours are now completed in just 1–2, even on complex branch layouts. Supports and fittings are costed consistently to rules, reducing surprises after award. Faster throughput on tenders means less admin and more focus on live projects, with the team noting, “All that time saved has allowed us to concentrate on the jobs that we have won.” Assemblies also provide transparent, auditable breakdowns that align with how ductwork is built, giving clients and QSs greater confidence.
