THE PROBLEM
Manual estimating drains time and adds risk. Every pipe, valve, pump, and fitting must be entered by hand, making duplication or missed items inevitable. Spreadsheets don’t apply industry labour times or reflect live supplier prices, so costs are often outdated and margins unreliable. Updating rates across plantrooms, risers, or multi-floor systems takes hours, while a single error in labour or material costs can turn profit into loss. For contractors working to tight deadlines, spreadsheets mean slower tenders, reduced accuracy, and projects lost to faster competitors.
THE SOLUTION
Ensign Mechanical Estimating Software replaces spreadsheets with a purpose-built system designed around your trade. It connects to a 350,000+ item database — updated weekly with images, labour times, and assemblies — covering heating, hot water, cold water, gas, and plant. Your database is set up by Ensign’s data team with your trade discounts, supplier rates, and branding, so every estimate reflects real costs from day one.
Â
With intelligent assemblies, seamless integration from take-offs and BoQs, and automatic labour/material breakdowns, contractors complete estimates in minutes, not hours. Live profit tracking and instant tender reports give contractors complete visibility and confidence in every bid. The result: estimates that are faster, compliant, and more profitable.
