Before approval
Verify the actual selection.
- Approved aggregate, color, finish, and repair range
- Use-specific traction and cleaning approach
- Edge, bearing, joint, and sealant details
- Exterior mixture exposure and maintenance requirements
Specific material planning profile
A refined ground finish exposing fine aggregate, with mockup control, edge protection, wet-use suitability, and joint discipline central to selection.

How the five-point scale works
The Registry uses this scale to show how much project-specific specification attention a factor deserves for Honed precast concrete. It is an editorial planning framework, not a laboratory result or product certification. No factors are averaged into an overall grade.
Levels are assigned from two questions: how consequential an unresolved factor could be, and how specific the evidence must be before commitment. They do not predict service life or failure.
Confirm the standard submittal and installation requirements.
Review the factor, but it is unlikely to control the decision by itself.
Give the factor explicit project-specific specification attention.
Resolve the factor before approval because it can materially affect the result.
Require source-, product-, exposure-, or assembly-specific confirmation before commitment.
Specification-attention profile
Every score below belongs to the named factor for Honed precast concrete. It does not describe the other examples in architectural concrete.
Aggregate, paste color, honing depth, production sequence, and repairs must match an agreed range.
A refined finish must still suit pools, snow, ice, cleaning, and barefoot circulation where applicable.
Chips, tolerances, bearing, joint width, and sealant appearance can dominate the installed result.
Dense appearance does not remove the need for exposure classification, drainage, and deicer planning.

Owner questions
Evidence and limits
These sources support the broader material-system principles. The five-point values are contractor-informed Registry editorial judgments under the published rubric; the sources do not assign those numbers. Current manufacturer literature, project specifications, source-specific test data, and local requirements must govern the actual selection.
