AI Tools That Handle This Role
A regional construction firm in the Midlands was spending £52,000 a year on a junior Cost Engineer whose primary job was 'takeoffs'—measuring drawings to estimate materials. They replaced 80% of that workload with Togal.ai (costing roughly £2,400/year) and integrated their accounting software with Power BI. The result? They cut their bid turnaround time from 6 days to 48 hours and reduced human error in material estimates by 12%. They now use a freelance Senior Surveyor for one day a month to verify the data, saving over £40,000 annually.
Penny's Take
Cost engineering is currently being bifurcated. The 'bean counting'—takeoffs, data entry, and basic forecasting—is now a solved problem for AI. Tools like Togal.ai can do in seconds what used to take a junior engineer a full weekend. If your cost engineer spends more than 20% of their time in Excel spreadsheets or manually measuring PDFs, you are burning cash. AI handles the 'Cost' part better than any human because it doesn't get bored and it doesn't miss a decimal point when processing ten thousand rows of data. However, the 'Engineer' part—the professional judgment—remains human. AI can tell you that your concrete costs are 15% over budget, but it can't tell you that the site foreman is cuting corners or that a specific subcontractor is about to go bust. The smart transition is to move away from a full-time mid-level role and instead use a senior consultant for 5 hours a month to audit the outputs of an AI-driven system. This is 'Thin Operations' in practice: high-level oversight, low-level automation.
