In the next month or so I need to layout a sidetrack that is going to go into a building for about 500 feet. I will be giving them an offset to centerline. The issue is is that will be a lot of construction traffic in the area that the offsets will be in. Usually for interior layout I use tape on the floor or marker and possibly some clear coat to spray over the marks. I don't think this will work because of the high traffic and construction activities in the building during the rail construction. I'm going to propose that they let me drill small holes along the offset line that way if the labels get worn away, the offset marks will still be there. What do you guys think about that idea or do you think there is a better way to go about this?
Thanks in advance.
Scribe marks with clear coat or small drill holes. Both are equally effective and recoverable.
Superior idea
But, first, mount a superhard, one-quarter inch or smaller punch onto the tip of the standard point.

Maybe a concrete scribe as seen here:

This is for a Railroad spur?
if so, chisel an "X" in the slab and spray paint it.
No tripping hazard / solid / remove at end of job if need be
Dremel with cutting tool to cut small deep crosses.
I use a RotoZipp with a ceramic cutting bit to mark an X or just to punch a small hole. If I were working in a building I would do as suggested above and put a clearcoat or epoxy to fill so that I will leave a small dot. The layman will be none the wiser. Let us know what you decided and how it worked out. Cheers
Hi,
a little old school but still fully functional for new and worn out concrete floors.
The Ironside Carbide Tipped Scriber,
I use the mini construction level to make the traces in the concrete. Be sure to have a small hand brush when you need to find them back later, or even some water to clean the trace when it is in the traffic zone.

Big project I worked years ago. Had another surveyor that had spent many years doing this.
Use a concrete scribe to make a cross (use a square to make fine straight lines). Then color in opposite sides of the cross with a permanent marker (called this a butterfly). You can clear coat but probably not needed. You can remark (color) if/when needed. In good concrete you can find the cross years later.
