Palm Beach County design work runs on record drawings that were never surveyed to a defined accuracy standard, and the cost of that shows up late. A proposed storm line is set at an invert that clears an existing main on paper, the contractor mobilizes, and the main turns out to sit higher than the record shows and offset from the plan alignment. Subsurface utility engineering under ASCE 38-02 exists to move that discovery into the design phase, where it is a redline instead of a claim. For engineering firms, the value is not only the marks on the ground; it is a documented, quality-level-labelled utility picture that can be defended in a design review and carried into permitting.
US Utility Potholing provides subsurface utility engineering services throughout Palm Beach County, including West Palm Beach, Boca Raton, Delray Beach, Boynton Beach, Jupiter, Wellington, and Palm Beach Gardens. We are licensed and insured, and we work directly for civil engineering firms, general contractors, municipalities, and electric utility crews. Our scope covers the full progression: records research, electromagnetic induction locating and ground penetrating radar designating, and vacuum excavation test holes where the design needs measured elevations. Field positions are captured on sub-inch accurate GPS and delivered as a KMZ Google Earth overlay with CAD and PDF.
The Design-Phase SUE Workflow, Start to Finish
We structure Palm Beach County scopes around the four ASCE 38-02 quality levels, because that is how design decisions actually get made. QL-D is records research: requests to the county water and wastewater utility, the municipal systems in cities that run their own, FPL, gas, and the telecom carriers with plant in the corridor. QL-C correlates those records to visible surface features such as valve boxes, manholes, pedestals, pull boxes, and meters, so the records can be checked before anyone brings equipment out. Neither level involves measurement, and neither should be treated as a basis of design on its own. Records research is also where scope gets defined honestly, because the gaps in the record are what determine how much designating and how many test holes a corridor will actually require.
QL-B is the designating step. Crews sweep the site with electromagnetic induction equipment and ground penetrating radar together, trace what is traceable, interpret what is not, and record horizontal alignments on sub-inch accurate GPS. QL-A is the test hole: vacuum excavation exposes the facility and we measure top-of-pipe elevation, outside diameter, and material at a specific station. Most projects need QL-B across the whole work area and QL-A at a limited, deliberately chosen set of points. Deciding which points those are is a design conversation, and it is worth having before the crew mobilizes.
Conflict Matrices and Where the Test Holes Go
Once designating is complete, the useful product for a design team is a conflict matrix: each existing utility crossing or paralleling the proposed improvement, listed with its designated horizontal position, what is known and not known about its depth, and whether the proposed work clears it, conflicts with it, or cannot be determined without a measured elevation. That third category is the one that drives the test hole program, and it is usually a much shorter list than a blanket allowance would suggest.
From there, test holes are placed where elevation controls the design: proposed storm and sanitary crossings of existing pressure mains, drilled shaft and pile locations, retaining wall and box culvert footprints, and any point where the designating marks show two facilities sharing what appears to be the same trench. Each hole returns a measured elevation that either clears the conflict or defines the relocation. Along constrained corridors such as I-95, the Florida Turnpike, Okeechobee Boulevard, and US-1, that distinction decides whether a design proceeds or a utility agreement has to be negotiated. Each hole is located on sub-inch accurate GPS and tied back to the designated alignment, so the matrix closes out with measured values rather than notes about what still needs verifying.
What Designating Can and Cannot Tell You
Designating establishes horizontal position. It does not establish depth, and we do not present it as though it does. A depth estimated from electromagnetic signal geometry depends on assumptions about the conductor and the surrounding soil, and ground penetrating radar depth readings drift with the South Florida water table because the calculation depends on signal velocity through the soil, which moves with moisture content. Palm Beach County sites near the coast, alongside canals, and in the western communities around Wellington all see that variation. Where a designer needs an elevation they can put in a design file and defend in a review, the answer is a test hole. That is the one method that returns a measured number.
Permitting Submittals and Design Review
SUE deliverables get read by people who were not on site, so they have to stand on their own. We issue the utility picture as a KMZ Google Earth overlay for field and stakeholder review, a CAD file that references directly into the design model with layers separated by owner and type, and a PDF for the submittal package. Every line carries its quality level, and every test hole carries its measured elevation, material, and diameter. A reviewer at a municipality or a utility owner can see precisely what was verified and by what method.
That documentation also supports utility coordination correspondence and relocation agreements. When a design in Boca Raton, Delray Beach, Boynton Beach, Jupiter, or Palm Beach Gardens requires an owner to move a facility, the request carries more weight with a measured elevation and a GPS-located test hole attached than with a note referencing a record drawing. The same package supports the contractor at bid time, which tends to reduce the utility contingency being priced into the job.
Frequently Asked Questions — SUE in Palm Beach County
At what point in design should we bring in SUE?
Records research and designating are most useful before alignments are fixed, typically around the thirty percent stage, so conflicts shape the design instead of interrupting it. Test holes can come later, once designating has identified which crossings actually need a measured elevation. Bringing SUE in after plans are complete still reduces construction risk, but it converts findings into redesign rather than design decisions.
How many test holes does a Palm Beach County project need?
It depends on how many crossings elevation actually controls, which is why we designate first and build a conflict matrix before pricing holes. A short roadway or drainage project may need a handful at specific crossings; a corridor project with multiple pressure mains and deep structures needs more. Placing holes from a conflict matrix rather than a uniform allowance usually means fewer holes and better-chosen ones.
Can you work in active rights-of-way and restore the surface?
Yes, and vacuum excavation is the reason. A vac truck or air and barrel soft dig removes soil without mechanical contact, so the facility is exposed without damaging coating, conduit, or wrap, and the hole is backfilled and the surface restored in kind. On roadway and sidewalk work we core, excavate, and patch, which keeps disturbance to the footprint of the hole rather than an open cut.
Why Work With Us in Palm Beach County
- Full QL-D through QL-A scope: Records research, surface correlation, geophysical designating, and measured test holes handled by one crew on one Palm Beach County project.
- Conflict matrix before test holes: Designating results are reduced to a crossing-by-crossing conflict list so holes go where elevation actually controls the design.
- Submittal-ready documentation: KMZ, CAD, and PDF labelled by ASCE 38-02 quality level for design review, permitting, and utility coordination.
- Measured elevations, not estimates: Depth comes from vacuum-excavated test holes, because GPR depth readings drift with the South Florida water table.
- Licensed and insured: We work for civil engineering firms, general contractors, municipalities, and electric utility crews across Palm Beach County.
