Treat monuments as project assets with a plan, not an afterthought [1].
- Inventory first: locate property corners, control and benchmarks before mobilization. Photograph and tie each one.
- Put it in the plans: show monuments to protect on the demolition and site logistics plans, with protection details such as barricades, sleeves or offset references.
- Set witness and offset points outside the work limits, so lost points can be restored quickly.
- Brief the contractor: walk the site with the superintendent and explain the cost of replacement.
- Check after major phases: re-observe control after demo, mass grading and utility installation.
- Document resets: file any required corner records when monuments are replaced.
A short protection clause in the contract, with the cost of restoration assigned, changes behavior quickly [2].
