Cost, time and contracts
Why do the planner, the QS and the contract matter to the model?
Project controls, estimating and procurement explained for BIM people: baselines and critical paths, measurement and cost, procurement routes and contracts, and how model data feeds them.

Short lessons with a quick check
- Lesson · 3 min · quizProject controls in plain wordsProject controls are how a project knows whether it's on time and on budget: a baseline programme and budget, regular progress updates, and reports that compare the two. BIM data feeds them, which is why controls people ask you for things.
- Lesson · 2 min · quizEstimating and quantity surveyingEstimators and quantity surveyors turn designs into money: measure quantities, apply rates, build cost plans and value change. They trust model quantities only when classification and measurement rules are clear, which is where you come in.
- Lesson · 2 min · quizProcurement and contractsHow a project is bought (the procurement route) decides who designs what, who carries which risks, and when the contractor joins. That shapes who owns which models, when information changes hands, and what your BIM requirements can demand.

The one I see most often on real projects: updating the plan without keeping the baseline. Tick off the checklist as you put each thing in place.
Common mistakes
What goes wrong most often on real projects.
- Updating the plan without keeping the baseline.
- Sending model quantities without saying how they were measured.
- Information requirements that never reach subcontracts.
