Stormwater in a town where a runway, hotel towers and office campuses share a small footprint has to be managed site by site, and the owners who build here need a contractor that can grade, drain and pour without disturbing the neighbors. We plan and coordinate earthwork, storm drainage, detention and the concrete that follows, scheduling and inspecting the trade partners and keeping the survey and test records the city expects.
Addison Airport is owned by the town and has one concrete runway measuring 7,203 by 100 feet on 368 acres. FAA data dated January 25, 2024 lists 576 based aircraft, and the field handled 119,065 operations in the year that ended September 30, 2023. The airport occupies roughly one-eighth of the town's area, so a very large share of the ground is paved, and runoff from those surfaces has to be handled by a drainage system that works with the lots around it.
Our work follows that setting. A hotel, office or industrial owner near the field wants graded pads that drain quickly, inlets that stay clear and slabs that do not move when the clay beneath them wets and dries. We start with the geotechnical report and the civil drawings, then compare them with what the ground tells us once excavation starts. Differences between the report and the open excavation are recorded, photographed and reported to the engineer the same day, so a decision is made while equipment is still on site.
Working near an airfield and busy roads
Construction close to an airport brings height limits for cranes and equipment, restrictions on lighting and dust, and rules for contractors who enter airfield areas. We confirm those requirements with the owner and the airport operator before mobilizing, and trade partners are briefed on them before work starts. Any equipment that rises above a set height, such as a crane or a long-reach excavator, is cleared in advance, and dust control is tighter near runways and taxiways.
On the ground, we apply the usual excavation controls: trench protection, barricades around open detention basins, spotters for equipment and daily site walks. Busy roads such as Belt Line Road call for traffic control plans and clean haul routes.
Clay, compacted fill and urban sites
Developed lots can sit on fill left from earlier construction, and soft pockets can turn up when old foundations or utility trenches are exposed. We probe suspect areas, remove unsuitable material and replace it with compacted select fill. Where the report calls for it, we condition the subgrade with moisture or lime treatment before building pads are shaped.
Tight sites leave little room for ponds, so underground detention, oversized pipe and trench drains often take the place of open basins. Those systems need accurate inverts and tested joints, and we survey them as they go in. Underground chambers also need a plan for inspection access and cleanout, which the owner's maintenance staff will rely on for years after the contractor leaves.
Hotels, offices and corporate campuses
Corporate headquarters for Dresser, Daseke, Mary Kay Cosmetics and Wingstop are in the town, which also has 22 hotels offering over 3,000 rooms plus more than two million square feet of office space. Buildings of that kind generate steady demand for renovations, parking structures, new pads and drainage upgrades.
Owners of occupied buildings seldom want a long construction disruption. We schedule noisy and dusty work for off hours where we can, keep access to entrances and garages open, and phase grading and paving so tenants can park throughout. When a hotel remains open, we also place barricades and signs for guests and delivery vans, and we clean the site daily so dust and debris do not reach the entrances.
Developers, contractors and public owners
Our drainage and grading packages serve commercial developers, general contractors who need a site ready for vertical work, and public owners handling roads and drainage. Each wants a different kind of communication, and we adapt our reporting to match.
Completed in February 1999 after three years of work and $26.8 million, the Addison Airport Toll Tunnel carries Keller Springs Road beneath the airfield, which eased congestion on Belt Line Road. Underground work of that kind shows how much of Addison's infrastructure lies out of sight, and why owners should confirm utility and drainage locations before digging. For owners of hotels and office buildings, a pre-dig review of utility records, plus potholing at crossings, is cheaper than repairing a damaged line.
Survey, build, verify
We stake the pond or pipe, build to the plan elevation and survey again before backfill. Embankments are compacted in lifts and tested, outlet structures are set to the approved elevation, and the final grade is checked against the plan. Low spots are fixed before paving covers them.
For slabs, we manage subgrade moisture the same way. Prepared ground is protected from rain, re-checked before steel goes in, and covered quickly by concrete, since an exposed base picks up water within hours. We schedule the forming crews and the pump so there is no long gap between final grade approval and the pour, and we record the weather on each placement date.
Services that work with the grading
Grading sets the base for other trades, so we coordinate storm drain installation, detention and retention ponds, building pad preparation and concrete paving in one sequence. Doing the underground first keeps trenches from being cut through new pavement.
We also coordinate trench drains and concrete drainage where loading areas, plazas or garage ramps need to collect surface water quickly. These systems are poured in place or set as precast channels, and the grate class is chosen for the loads that will cross it, whether that is pedestrians or a delivery truck.
Neighboring towns along the tollway
Addison lies along Belt Line Road and the Dallas North Tollway, with a rail line running through town. That position puts it close to Farmers Branch, Carrollton and Richardson, and owners often compare drainage and grading approaches in those cities when planning a portfolio.
We keep trade partners and plant capacity in mind across the area, so a schedule that serves one site does not conflict with another. Owners with several buildings in the area benefit from one point of contact for the drainage and grading scope, since a single sequence reduces rework and keeps records consistent across properties.
What a drainage and grading package includes
A typical package covers clearing, demolition of old pavement, cut and fill, fine grading, storm pipe, inlets, detention, erosion control and final grade survey. Concrete scope often follows with building pads, parking and flatwork.
We provide separate prices for each part so owners can see the effect of design choices, and we document each step with photos, survey data and test reports that go into the closeout package. As-built survey data of pipes, structures and ponds is delivered in the format the city or the owner's engineer requests, so the next contractor knows exactly what is underground.

Common Questions
How do you manage drainage on a small urban lot?
We use underground detention, oversized pipe, trench drains and graded surfaces, combined to meet the city's requirements. The design starts with the engineer, and we verify inverts and slopes as the pipe goes in.
Does the airport affect construction?
It can limit crane height, lighting and airfield access, so we confirm requirements with the owner and the airport operator early. Planning avoids last-minute changes to equipment or schedule.
Can you work while a building is occupied?
Yes. We separate work zones, protect entrances and garages, keep noisy work off peak hours and give tenants regular updates. Phasing lets parking and access continue.
How does soil affect a slab on an urban site?
Fill, old foundations and clay can all make subgrade uneven. We probe, remove unsuitable material, compact select fill and control moisture before the slab is poured.
What do you need to price a grading package?
Send the civil plans, geotechnical report, utility survey and target dates. We price earthwork, drainage and concrete separately, and we note assumptions about unknown ground.
