Questions about cost estimators and AI

Will quantity surveyors be replaced by AI?

Partly. About 5 in 10 working hours go to tasks AI can already do, mostly keeping supplier directories current and preparing cost and expenditure statements. What stays with people is site visits, client and foreman talks, and negotiation with contractors.

Will AI take over quantity surveying?

AI can already do 35% of the task time in quantity surveying and speeds up another 51%. People still do 14% of it. The US has 224,220 cost estimator jobs, with a projected change of -3.1% from 2024 to 2034.

Which tasks is AI taking over for cost estimators?

Supplier directory upkeep comes first, with an exposure score of 80, because AI maintains records and flags outdated contact details. Cost and expenditure statements follow at 75, since AI drafts them from ledger data for the estimator to review. Historical cost data collection scores 72, as AI queries and cleans past records while the estimator checks which ones still apply.

Which tasks stay human for cost estimators?

Site visits stay human. Someone has to stand on the ground to record access, drainage, topography and utility services. Resolving issues with clients and construction foremen needs live judgement, and so does negotiation with contractors over the final price.

How can cost estimators stay valuable as AI takes over tasks?

Check every AI quantity takeoff in PlanSwift or On-Screen Takeoff before pricing it. Track actual costs against bids in SAP and Excel, and explain each overrun to the manager who is responsible for the budget. Take responsibility for the tender comparisons and subcontractor negotiations, which stay with people.
