Edges influence the connection detail
Concrete near an edge is not the same setting as concrete extending well beyond the anchor group. Product and design requirements may address edge distance, spacing, member thickness and reinforcement conditions together. The visible edge of a paver or finish is not necessarily the edge used for the structural check. Identify the actual supporting element.

An extra hole is not a harmless layout change
Moving an anchor to avoid an old hole can change its relationship to edges and other anchors. Ask the contractor what reviewed repair detail covers the new position. Additional anchors do not automatically compensate for unsuitable locations. Keep existing abandoned holes and damaged areas in the condition record rather than covering them without documentation.
A practical homeowner example
A replacement base would put a hole close to a slab edge. The contractor checks the base layout and anchor requirements instead of simply shifting the hole to the nearest convenient spot.

Questions to bring to an estimate
- Keep the document title, applicable version and project identification together.
- Ask who determines the criteria or approval basis for this particular scope.
- Retain the governing documents and written resolutions of changes.
Frequently asked question
Is edge distance the same as anchor spacing?
No. Edge distance relates an anchor to a substrate edge. Spacing relates anchors to each other; both can be relevant to the design.
