“Before Ensign, every estimate was hard work… We switched and it was an excellent decision — a small investment that gives a big saving and creates certainty for us and our clients.”
GPQ’s team ran a 3–4 step, paper-heavy workflow. Allowances for supports and access doors varied by estimator, and manufacturing details (gauges, flanges, pressure class) weren’t always applied consistently. That meant long take-offs, last-minute rework, and avoidable queries from QSs.
GPQ adopted Ensign Ductwork Take-off & Estimating with DW144 and TR19 rule sets built in. Pressure-class logic applies gauges, reinforcement, and flanges automatically, while supports and access doors are generated to spec and fully scheduled. Complex risers and mirrored branches clone in seconds, keeping everything auditable.
With quantities flowing straight into Estimating, GPQ now produces accurate SORs, breakdowns, and branded tenders in clicks — no re-keying, no wasted time.
By replacing 3–4 separate stages with one streamlined process, GPQ now saves significant time on every tender. Standards-led allowances for supports, gauges, and access doors mean fewer post-award variations, while live cost build-ups give clearer margin control and profit certainty. With DW144/TR19 schedules and fully auditable drawings, QSs and clients have greater confidence — and GPQ credits the system with helping the business grow.
