Roy Kizer Golf Course: Bunker Rehabilitation Modeling

The ask

Roy Kizer is a municipal course, and the city was weighing a change order to rebuild the bunkers. Before that could move forward, someone had to put a real number on it: how much sand, and what it would cost. A walk-the-course guess doesn’t survive a public budget review.

Working from data we already had

We didn’t fly it again. We already had the course terrain from the lake project, captured finely enough to model every bunker floor and face, so the whole takeoff came out of data the client had already paid for.

Every bunker, measured

We traced all forty-one bunkers and modeled the depth across each one, deeper in the floor and thinner up the faces where sand slides off. That gives a real volume per bunker instead of an area times some assumed depth. All told, the course comes to 689.1 cubic yards, about 965 tons of sand.

What it costs

Sand volume is only useful once it turns into dollars. We carried the tonnage across three price tiers, from a local silica blend up to premium white sand, so the city could see the range and pick a spec. Course-wide, the sand lands between $65,000 and $140,000 depending on the grade.

What it gave them

They walked into the city with a real number instead of a guess, and a clear line on what it covered: sand, and only sand. Excavation, liner, drainage, labor, and finish grading all stay separate bid items. We gave them the quantities and the cost range the change-order request was built on.
