Last spring, behind a retail plaza in Bradenton, the crew opened a trench for what was supposed to be a clean conduit run. Paper said routine. Two days in, we hit an abandoned service line that wasn’t on a single drawing, then an irrigation manifold, then about six feet of unmarked fiber that had no business being there. None of it was in the bid. The owner did not love that conversation.
That kind of surprise is exactly why commercial underground electrical utility installation rarely tracks the way the spreadsheet predicts. The situation described in rac.co.uk, “The road to electric – in charts and data [UK]” points to something we feel down here too. More EV load, more data demand, more buildings pulling harder on infrastructure that was buried decades ago by people who are long retired. The ground under most Florida commercial sites is a mess of half-documented runs.
Honest opinion. Most trench problems are not electrical problems. They are planning problems. Locates get treated like a formality. Soft digs get skipped because the schedule is tight. Then somebody is standing over a trench at 4pm trying to figure out who owns the cable they just exposed.
If a property is adding load, whether that’s EV chargers, a new build pad or a new service entrance, the underground work is where the budget either holds or falls apart. Conduit routing, depth, separation from other utilities, transformer pad coordination with the POCO. None of that is glamorous. All of it costs money when it’s missed.
I’d rather over-investigate a site than write a change order. Customers say the same thing after the second one.
A few things we get asked all the time.
Why does underground work cost more than expected?
Because what’s already buried rarely matches the drawings. Old irrigation, abandoned conduit, unmarked telecom. Every surprise is time, and time is the line item that grows.
Can you trench near an active building without shutting it down?
Usually yes, depending on routing and how close we are to the existing service. Coordination with the utility and a clean plan around the existing electrical equipment is the part that matters.
How deep does commercial conduit need to go?
Depends on the voltage and the location. Under driveways and parking is different from open landscape. Code minimums are a starting point, not the goal.
Do I need a new service if I’m adding chargers or equipment?
Not always. Sometimes the existing service holds. Sometimes it does not. A load study before the trench gets dug is cheaper than figuring it out halfway through.
Skip the locates and you’ll pay for them anyway, just later and with more witnesses.
