A filled swim spa can weigh as much as several cars on a small footprint, so it needs a reinforced concrete slab built to the supplier's published requirements.

Built to the supplier's requirements
Every hot tub and swim spa maker publishes what its base must carry and how level it has to be, and an out-of-spec base can void the warranty. We build to those requirements and can give the supplier a written method statement.
We plan delivery day too: the crane or wheel route, any fence panels or gates to lift, and where the drain-down water goes.
Part-sunk and fully sunk
Sinking a spa means digging out, building retaining walls, drainage at the bottom and access to the equipment bay for servicing. It is a bigger job and is priced after the visit.
