An operating dental expansion in Wentzville
Our Wentzville project expanded an operating dental practice with five treatment rooms, nitrous oxide, oxygen, compressed air and vacuum. The work also included a sterilization area, an ADA restroom rework and concrete floor patching after underground work. The gas lines connected back to existing tanks, while sink cabinets and underground connections were part of the same expansion. This is an existing-building project, not a claim about a new hospital or a manufacturing installation in Wentzville.
That scope illustrates the questions worth resolving before a tenant expansion: which systems stay in service, where new branches connect and which floor areas need to open. Clinical equipment locations and sterilization needs affect rough-in, while occupied operations affect access. Our tenant finish and medical gas pages explain those existing offerings. For a different building type, send its plans rather than assuming the dental layout is a standard package.
Nearby county evidence is different. Foristell has a listed cold storage construction project, and O'Fallon has ground-up commercial site utilities. The area section labels those towns explicitly and ranks the work using the existing project location data. A nearby industrial project supports comparison of underground and water-heating scope, but it is not relabeled as work in Wentzville. Regular service is Monday–Friday, 7am–4pm from our O'Fallon office.
