Before a distribution building or a commercial center in Roanoke can open, its water, sewer, storm and electrical lines have to be in the ground, tested and covered. For owners and general contractors, we coordinate that underground work with the concrete that follows it: trench excavation and bedding, pipe and structures, backfill and compaction, and the slabs and pavements that will sit above all of it.
Byron Nelson Boulevard, which is State Highway 114 Business, carries most of the east-west traffic through town, and a site along it often has to connect to lines that already run beneath the roadway. Northwest Regional Airport is two miles north of the city center, so industrial and commercial uses are drawn to the area for both road and air access. Tying into existing mains, crossing a state route and meeting a city inspector's standards are normal parts of a Roanoke project.
We schedule, coordinate and inspect the trade partners who excavate, lay pipe, set structures and place concrete. The results are documented from the first trench to the final cure.
What changes the underground plan
Depth, groundwater and rock decide how a trench is cut. We review the geotechnical report for rock, wet zones and soft areas, then decide on shoring, dewatering and bedding. Utility potholing locates existing lines before excavation so a surprise crossing does not stop the work. In this part of North Texas, utility potholing and locating is a low-cost step that saves schedule.
Sequence matters as much as method. Deep lines go in first, backfill is compacted in lifts and tested, and the building pad is not poured until trenches that cross it are closed. Reversing that order is a common cause of settlement. Where clay is present, trench backfill near the building is chosen and compacted to avoid creating a channel that carries water toward the slab edge.
Buildings that depend on the lines
The logistics and distribution buildings in the area need large fire lines, hydrants and storm systems that handle roofs and truck courts. Office and retail users need smaller services but more of them, and light manufacturing may need process water or electrical capacity. We build the underground package to match, from distribution center lines to the connections for flex and light industrial buildings.
Fire protection lines receive special attention since the fire marshal tests them before occupancy, and a failed test late in the schedule is expensive. Sanitary connections for restrooms and break rooms, grease or sand interceptors for food and service tenants, and storm connections from roof drains all have to be located before the slab is placed.
Working along the 114 and 377 corridors
Roanoke is close to Keller, Southlake and Flower Mound, and developers often assemble sites that cross these city lines. Each city has its own inspection process and its own details for manholes, hydrants and trench patches, so we collect the standards early.
We keep pipe, structures and aggregate sources within a reasonable haul, and we reserve deliveries before a trench is opened. That reduces the time an open excavation sits exposed to weather and traffic.
Trench to cure, one record
We begin with the utility plan and the soil report, then set grades, stake lines and confirm inverts before pipe is laid. Bedding, pipe joints and backfill lifts are inspected and tested. Structures such as manholes, inlets and vaults are set to grade and checked against the plan before concrete or asphalt reaches them.
At the end, the owner receives as-built information, test records for pressure, compaction and concrete, and photographs where useful. If a field condition forces a change, we record it so the final drawing matches the ground. That record is what a future owner or utility crew will rely on when they need to find a valve or a manhole years from now.
Logistics, roads and a large employer base
A 568,632 square foot industrial building on 68.6 acres, about two miles east of I-35 and SH 114, was delivered in 2021 with 119 dock doors and 36-foot clear height, and an October 17, 2022 report said it sold fully leased to UNIS. A facility of that size needs substantial utilities and a drainage plan that holds roof and pavement runoff.
The city's 2022 financial report lists General Motors with 460 employees, WW Grainger with 450, Martin Brower with 450, Walmart with 400 and Randall's/Tom Thumb with 360 among its top employers, which shows a mix of manufacturing, distribution and retail demand.
Where the money goes underground
Pipe diameter, depth and the amount of rock or dewatering are the largest cost drivers. Traffic control and pavement restoration add cost when a line crosses a public road. Structures, such as vaults and large manholes, have long lead times that can affect both price and schedule, so we recommend releasing submittals early. Weather days add cost on open trenches, and a plan that keeps excavation open for the shortest time is usually the least expensive plan.
A December 2023 report described a TxDOT plan to turn US 377 between FM 1171 and Highway 114 into a divided road with two lanes each way, at about $80 million and without a construction date. Owners should allow for possible conflicts and utility relocation in that corridor.
The package we coordinate
A typical scope includes sanitary sewer installation, water mains, fire lines and hydrants, storm sewer, manholes and inlets, conduit and duct banks, and trench backfill. We also handle the concrete work that supports them, such as thrust blocks, vault slabs and headwalls.
Detention areas, mass grading and fine grading belong to the same plan, because the grades that shed water from the pad also set the cover over every pipe. We sequence pipe, structures and subgrade so that the site is never torn up twice.
Who hires us for this work
Our underground work serves logistics and warehouse developers, general contractors, commercial developers and municipalities. Each needs the same technical result but a different contract structure and record set, and we adapt our proposals and reporting to suit. A developer may want a lump sum with clear exclusions, a city may want unit prices, and a general contractor may want a schedule that matches the master plan.
Developers who also need drainage and grading can combine those scopes with the utilities for a more efficient site sequence.

Common Questions
How do you avoid hitting existing utilities?
We request locates, review as-built drawings and pothole at crossings to confirm depth and position before machine excavation. Hand digging is used near live lines, and we keep a log of every crossing found so the as-built drawing shows what was actually in the ground.
Who tests the pipe and the fire line?
The city or fire marshal witnesses pressure and flushing tests, and a testing lab handles compaction and concrete. We schedule each test and keep the reports.
Can utilities and the building pad be built in the same season?
Yes, if the utility sequence is planned first. Trenches crossing the pad are backfilled and tested before slab preparation starts.
What if rock shows up in the trench?
We check the geotechnical report first. When rock is encountered, methods may include a heavier excavator, a hydraulic hammer or blasting where permitted, and the contract should say how it is priced. Agreeing on a rock allowance before work starts keeps a hard layer from becoming a dispute.
