Preparation guide before coring or cutting
A short list, drawn from what we already publish, so that a visit is worth something on the first pass.
What the guide contains
To settle before the visit
- Define the working area rather than the whole floorA survey seldom covers an entire floor plate.
- Clear the surface and secure antenna contactContact with the concrete governs signal quality.
- Gather the documents and the site constraintsAvailable drawings, even old ones, help interpret the echoes.
- Agree on access and power before the visitA survey means moving equipment around, sometimes through locked rooms or via a restricted service lift.
- Plan what happens right after the surveyA survey produces floor markings and a report.
How the survey unfolds
