If safety in the workplace is a concern, let’s talk about. A single serious OSHA violation starts at $7,000

Frequency selection isn’t about the utility. It’s about what’s around it. One of the most common mistakes I see in the field — techs defaulting to the same frequency every single time regardless of the environment. That’s how you end up marking the wrong line. Here’s how I think about it: 512 Hz is your long distance specialist. Minimal signal bleed, ideal for trace wire and telecom runs. Direct connect only — inductive clamp won’t work at this frequency. 8 kHz is your everyday workhorse. Solid range, works with both direct connect and inductive clamp, good balance between signal strength and bleed control. 33 kHz gives you a stronger signal and better clamp performance — but in a congested utility corridor, that stronger signal bleeds onto adjacent lines. Know what’s around you before you dial it in. The environment drives the frequency choice. Always.
The three frequencies:
512 Hz
Long distance | Trace wire | Minimal bleed
8 kHz
Everyday workhorse | Direct connect & clamp
33 kHz
Stronger signal | Watch bleed in dense corridors

Utility strikes rarely happen because someone was careless. Before excavation starts, it’s worth asking: What level of subsurface confidence does this project actually require? Subsurface work is risk management, not an afterthought.

I’ve been quietly building a new platform designed specifically for the Subsurface Utility Investigation (SUI/SUE) space. currently looking for:
• SUI/SUE providers interested in early access
• Municipal/commercial users willing to test workflows
Today, the Trump administration repealed the endangerment finding: the ruling that served as the basis for limits on tailpipe emissions and power plant rules. Without it, we’ll be less safe, less healthy and less able to fight climate change—all so the fossil fuel industry can make even more money.
If You’re Running High-Stakes Automation…
If your automation touches:
• infrastructure bids
• pricing logic
• contracts
• or client-facing deliverables
and you’re confident it can withstand scrutiny, I’d be interested in reviewing it.
Not to replace it. To stress-test it.
Building a decision-support system for SUE bids (intake, scope, production modeling).
Not agentic. No decision-making. Just fewer bad assumptions.
Looking for feedback from SUE / construction folks who bid linear footage and care about accuracy.
Still bidding on projects the “old way”?
How much of your bid prep still lives in your head?
I’m rebuilding intake → analysis → proposal generation. Cleaner, more defensible.
Testing on real projects. If manual prep eats time you’d rather spend elsewhere, let’s compare notes.
