Redeveloping large former industrial sites

When a large industrial site closes and is redeveloped, the new owners inherit an underground network built for a very different use: oversized water and fire mains, extensive drains and pits, storm systems for acres of roof and pavement, and conduit and vaults for heavy power. Some of it can be reused; much of it has to be abandoned or removed before new buildings go up.

The usual sequence:

Investigate

Gather the old drawings, mark live public facilities through Diggers Hotline, and dig test holes with hydro excavation at the points that matter.

Empty and assess

Pits, vaults and structures are emptied with a vacuum truck so their condition can be judged.

Decide

With the engineer and the utilities, decide what is reused, abandoned or removed.

Build

New services and site utilities are installed to the new layout, inspected by each owner and restored.

We also take on smaller jobs in Janesville, such as a home's water service or lateral, or a new connection for a business.

Notice before excavation

Diggers Hotline is Wisconsin's one-call center under Wis. Stat. 182.0175. The law requires notice at least three working days before excavation and has no fixed ticket life; a new notice is required when work does not begin within 10 days of the scheduled start or pauses for more than 10 days.

For a redevelopment site, send every record you have, however old, with the new plan. Where an old line is to be abandoned in place, the owner's engineer and the utility normally decide how it must be capped or filled. We reply with our questions and a proposed approach.
