Every engagement is scored against the same structure: one of four defined lenses, five maturity levels, three possible decisions. It is what turns a review into a rating, and a rating into a defensible recommendation, applied consistently, project after project.
Scope, commercial, buildability, cost efficiency. Each of the four services applies the one lens that matches its scope.
Each lens is scored Absent to Robust. Level 3, the bold ring, is the minimum pass.
Every score across every lens resolves to one of three calls. No other outcome is possible.
One framework. One lens per engagement.
Each review is scored against its relevant lens on the same five-level scale, from Absent at the outer edge to Robust at the centre. The bold ring marks Level 3, the minimum pass for every lens.
The discipline that holds across every engagement.
No interest in the outcome.
Depth matched to risk.
Ratings anchored to documents.
Applied before commitment.
Ends in a clear recommendation.
CALON's engagement window sits entirely before the tender package goes to market, and before a contractor is appointed. Everything after, procurement, award, delivery, commissioning, closeout, is outside scope by design, not by omission.
Every review ends in one of: proceed, proceed with conditions, hold.
Each of the four services maps to a single, consistent lens, rated from Level 1 (Absent) to Level 5 (Robust). Level 3 is the pass threshold applied on every engagement.

Level 3 minimum applies whichever lens a review covers — below that, the finding is recorded as a gap, not smoothed over. A Level 1 score is reported as a hold recommendation.
Independence is the product. The conflict screen runs before any engagement is accepted.
For the body that owns the project. Never the delivery side.
CALON assesses. CALON does not execute, design, or construct.
CALON does not assure work it has shaped.
