Vehicle and equipment plants
Plants that build or service large vehicles and equipment have heavy underground needs: wash bays with drains and separators, pits beneath work areas, large water and fire services, storm systems for big paved yards, and conduit for high electrical loads. Those systems take a lot of wear and collect a lot of material.
Typical jobs on such sites:
Cleaning
Hydro vacuum services empty separators, pits, trench drains and storm structures so they keep working and can be inspected, as the owner's requirements for the material allow.
Repair and replacement
Damaged drains and structures are exposed, often with hydro excavation near live services, and replaced during planned downtime.
Expansion
New services and conduit for new buildings or equipment, with crossings of yards drilled where vehicles must keep moving.
All of it follows the plant's drawings, site rules and safety procedures.
We also handle water service, lateral, storm and conduit work for homeowners, small businesses and public owners in Oshkosh.
Diggers Hotline
Under Wis. Stat. 182.0175, excavators contact Diggers Hotline before digging. Notice must be given at least three working days ahead; there is no fixed ticket life, but a fresh notice is needed if digging has not started within 10 days of the scheduled start or stops for more than 10 days. Private plant lines are not marked by that process.
