Clubs routinely rebuild greens with no accurate record of what was there. The regret arrives about two years later.
A club rebuilds its 7th green. Two years on, members say the old one was better, and the committee would like to understand what changed. There is no survey of the old green. There are some photographs and a lot of opinions.
This happens more often than it should, and the fix costs a fraction of the renovation.
What to capture, and when
Before any earth moves, capture the existing green complex properly: surface model, surrounds, drainage, and the approach for at least thirty metres. Not a sketch — a measured survey you could rebuild from.
The cost is trivial relative to a green rebuild. The value shows up in three places.
1. You can compare honestly
When members say the green is faster or the run-off is harsher, you can check rather than argue. Frequently they are right, and frequently the cause is a slope change nobody intended.
2. You can rebuild what worked
If one contour on the old green made a pin position particularly good, it is recoverable. Without a survey it is folklore.
3. Your other assets stay current
Yardage books, tee signage and flyovers all derive from course geometry. Renovate without updating the source data and every one of those becomes quietly wrong, usually noticed first by a visitor who trusted the book.
Who does this work
It is a CAD and survey job rather than a graphics one, which is why clubs often route it to the wrong supplier. Firms working specifically on course drawing and planning — CAD.Golf, for example — treat the existing-conditions survey as the first deliverable rather than an optional extra, and will usually supply it in a format your architect and your graphics supplier can both use.
The rule
Never move earth on a green complex without a measured record of what was there. It is the cheapest insurance in course management, and the only one you cannot buy retrospectively.
