Modern GBQGrace Estimation MethodFor estimators, architects and project managers
Work on your client's project without rebuilding their numbers
You are invited onto a project with a defined role, and you work on the same estimate everyone else sees — with the working shown on every line, so your judgement goes into the parts that need it.
Already have an account? Log in. Or read the guide for your role first — no account needed.
How it works
What you actually do
- 1
Get invited
The project owner adds you with a role — estimator, architect, project manager or administrator — which decides what you can change.
- 2
See the working
Every quantity names the formula that produced it, and every price names its source. Nothing is a black box you have to take on trust.
- 3
Refine it
Override any material selection with a reason, enter the quantities the formulas do not measure, and re-price. Every version is kept.
Worth knowing first
The honest limits
Better to read these now than to discover them after signing up.
- You see only the projects you have been invited to. There is no directory of other people's work.
- What you can change is decided by the role the project owner gave you.
