Top 100 Vocabulary for Adults | Quantity Surveyors & Cost Consultants
Quantity-surveying vocabulary is the language of measuring, forecasting and controlling the money inside construction. Quantity surveyors and cost consultants translate designs into cost plans, contracts into valuations, and project change into commercial consequences.
This professional flagship belongs to the eduKate Adult Vocabulary for Professionals system. It complements Construction Management Professionals, Facilities Management Professionals and Property Management Professionals.

Cheap Is Not the Same as Good Value
A lower tender can hide exclusions, unrealistic allowances or future maintenance cost. Cost consultants compare scope, quality, risk and whole-life consequences, not price alone.
Scenario: The Lowest Tender Is 15% Below the Others
Normalise the bids. Check omissions, qualifications, provisional sums, productivity assumptions and whether the bidder misunderstood the scope. A suspiciously low number may become an expensive contract later.
