Rebuild it without shutting it down.
Roads, interchanges, airfields, utilities and heavy sitework, delivered by crews who plan every lane shift, outage and tie-in around the people who rely on the network every day.
What is at stake.
The public drives through the jobsite
Commuters, freight and neighbors move through the work zone around the clock. Traffic control and safety are core scope.
Windows are short and fixed
Lane closures, runway shutdowns and utility outages come in tight, permitted windows. Miss one and the next may be weeks away.
The ground keeps secrets
Unmapped lines, soft soils and groundwater show up on nearly every civil job. A plan that expects them stays on schedule.
How we stage it.
- 01
Traffic staging
Phased traffic control, temporary pavement and lane switches designed so the corridor carries its load at every stage.
- 02
Earthwork and grading
Mass excavation, embankment and subgrade, run with GPS machine control and checked against the design surface.
- 03
Bridges and structures
Drilled shafts, substructure, girder sets and deck pours, with crane picks and closures planned in the same schedule.
- 04
Utilities and drainage
Storm, sanitary and water mains, relocations and duct banks, verified by test pits before excavation begins.
- 05
Closure-window scheduling
Night and weekend windows are modeled as hard constraints in the schedule, with fallback dates set before the first barrier moves.
What lands on your desk.
Scope is set project by project. These are the working documents you can count on, updated on a regular cycle and yours to keep.
Stage-by-stage lane layouts, detours and switch dates for agency review.
Every closure and outage mapped to the work it supports, with backup dates.
Known and discovered utilities, relocation status and owner coordination in one place.
Quantities and haul routes that reuse material on site and cut truck trips.
Closure notices, detour maps and updates you can share with the community.
Seven ramps. Rush hour untouched.
An old cloverleaf was rebuilt as a modern system interchange under a design-build contract. Every ramp shift was staged in the schedule against peak traffic, temporary pavement carried the movements in each phase, and every lane stayed open at rush hour from the first stage to the last.

What owners want to know.
Can the road or runway stay open?
In most cases. We phase the work so traffic or flights keep moving and reserve full closures for short, planned windows.
Do you self-perform civil work?
Our crews and equipment carry earthwork, utilities and concrete on many civil jobs. Specialty partners handle scopes like signals and striping where that fits.
What delivery models do you use?
Design-build, CM at-risk, general contracting and public-private partnerships. We help the owner match the model to the project’s risk.
What happens when we hit an unknown utility?
We stop, log it, bring in the utility owner and shift crews to other work in the sequence while the fix is agreed, so one conflict does not stop the job.
Bring us the schedule that worries you.
Share the drawings, the budget or the date you cannot miss. A GilbertLanham project lead will walk through the critical path with you and tell you plainly where the risk sits.
