Priority Service — Raw Land to Build-Ready
Turnkey Site Development
Turnkey site development means one civil contractor carries the site from raw land to build-ready — clearing, earthwork, stabilization, utilities, drainage, pads, roads, and concrete under a single contract and a single schedule.
It exists for general contractors, developers, and energy project teams who would rather manage one civil relationship than five overlapping trade contracts. TerraTek is based in San Angelo, works statewide, and self-performs the connected scopes with our own crews. In the raw-land-to-build-ready sequence, turnkey is not one step — it is the spine that holds the steps together, from the first clearing pass to the last slab our concrete crew finishes. This page covers what the package includes, how the interfaces between scopes are managed, and how to put a full civil package out for review. If you have ever watched a finished pad wait weeks for the next trade's mobilization, this is the delivery model built to make that wait disappear.
Why Turnkey Delivery Decides Whether Your Site Performs
On a typical project, the civil scope splits across a clearing sub, a dirt contractor, a utility contractor, a stabilization specialist, and a concrete sub. Every split is a bid package to manage, a mobilization to schedule, and an interface where responsibility blurs.
TerraTek closes those gaps by putting the connected scopes under one contractor: same company, same schedule, same accountability. The sections below walk through what that looks like scope by scope — and where the model earns its keep on real schedules.
The failure modes of fragmented civil work are specific. Scope gaps hide in the exclusions — five bid packages each marked "by others" at the edges, and nobody priced the trench compaction under the slab or the erosion control between phases. Mobilizations stack: each subcontractor arrives on its own calendar, so a finished subgrade sits idle losing its moisture conditioning while the next trade finishes another job across the state. And when something at an interface fails — a pad soft over a utility crossing, a storm line at the wrong elevation under new paving — the responsibility question turns into a three-contractor correspondence file instead of a repair.
Single-source delivery converts those interfaces into internal handoffs. One estimate covers the edges, one superintendent owns the calendar, and the crew that builds each stage knows it is handing the work to a colleague who will judge it. Here is what that buys the general contractor:
Fewer bid packages. One civil bid instead of five trade bids with overlapping exclusions — the edges get reconciled in our estimate instead of discovered in the field.
One schedule owner. Our crews sequence to each other — handoffs do not wait on third-party mobilizations, and when weather moves the plan, the whole plan moves together.
One point of responsibility. Questions at scope interfaces have one contractor to call — they get answers, not correspondence files.
Clean handoff to vertical. The site arrives foundation-ready with documentation aligned — compaction records, test results, and as-builts in one package.
The schedule math is the quiet argument. Civil delay compounds: a week lost at grading pushes stabilization into worse weather, which pushes utilities, which strands the pad, which floats the pour date the vertical contractor built a crew plan around. Fragmented delivery has no single owner for that cascade — every contractor can be individually on schedule while the project is collectively late. Turnkey gives the cascade one owner with the authority to resequence crews the same week conditions change, which is the only version of schedule recovery that does not arrive attached to a change order.
What Our Turnkey Scope Includes
The package flexes to the site, but these are the scopes it draws from — each also available stand-alone. Every item below is self-performed civil work, planned as one program rather than six adjacent contracts.
Land clearing & site access
The site is opened up before it is built up: clearing and grubbing to the limits of disturbance, construction entrances and haul roads that survive the whole job, and initial erosion controls in place before the first major cut. Access planned at this stage is what keeps concrete trucks moving in month six, so it is engineered for the end of the project, not just the beginning. Disturbance limits, protected areas, and the stormwater controls the permit requires are built into the clearing plan from day one.
Mass grading & earthwork
Earthwork and excavation bring the site to design grade: cut and fill balanced against the grading plan, building areas brought to subgrade elevation, and drainage shaped so the site sheds water through every construction phase instead of only in the finished condition. Compaction is executed lift by lift to the specification, because everything later in the sequence stands on this work. Cut-fill balance is managed as a cost item — export and import are decisions made on paper, not accidents discovered by the loader operator.
Soil stabilization
Where the geotechnical report calls for it, lime soil stabilization treats expansive or weak subgrade in place — spread, mixed, moisture-conditioned, and compacted to the engineer's rates and depths. Inside a turnkey package, stabilization is scheduled directly against the grading and pad work around it, which is exactly the interface that slips when the scopes are held by separate contractors. Treatment limits, rates, and depths come from the geotechnical engineer, and the treated layer is verified by the project's testing laboratory before anything builds on it.
Underground utilities & drainage
Wet and dry utility systems — water, sanitary, storm, and dry-line conduit — installed at the point in the sequence where trenching does not destroy finished work, with backfill compacted to the same standard as the subgrade around it. Erosion and drainage control is maintained across the life of the job, not just installed once for the preconstruction inspection. Crossings, sleeves, and stub-outs are logged against one control network, so the concrete crew finds them where the drawings say they are.
Pads, roads & finish grading
Building pads built and verified to the geotechnical requirements, roads and paving subgrade shaped to plan, and finish grading that ties pads, paving, and drainage into one surface that works. Supporting scopes such as retaining walls and detention and pond construction are folded in where the plans require them. Every pad is delivered with its verification records, because the next contractor's schedule depends on being able to believe the surface.
Site & structural concrete
The package finishes with commercial concrete: slabs and foundations, equipment pads, and site concrete placed by the same company that built the platform under them. The pour lands on a subgrade with a documented history — who compacted it, when it was tested, how it was protected — which is the cleanest possible handoff to the vertical contractor. It is also the stage where turnkey proves itself: no idle gap between a finished pad and the crew that pours on it.

Turnkey is not a separate step in this sequence — it is the decision to buy the sequence as one thing. Not every project needs every stage: a site with good soils may skip stabilization, and a project with utilities by the municipality may only need the dirt-and-concrete spine. What stays constant is that scopes that touch each other are planned together, by the contractor responsible for both sides of each handoff. The rail above is the default order for a reason — each stage protects the one after it.
The two scopes most sensitive to that planning are the ones deepest in the chain: lime soil stabilization, which must land after grading and utilities but before pads, and commercial concrete, which inherits everything. Where a project calls for specialty scopes outside our self-performed work, we say so plainly during review — the goal is a reliable schedule, not an overreaching promise.
Timing matters as much as order. Stabilized subgrade should not sit exposed through a wet season; trench backfill should be tested before paving traps it; erosion controls must outlive every phase that disturbs soil. A sequence is not a list — it is a set of promises each stage makes to the next, and turnkey puts every one of those promises inside one company. That discipline is what the package is priced around.
Who This Is For
Turnkey is industry-agnostic by mechanics but not by payoff — it earns the most where the civil scope is large, remote, or schedule-critical.
Commercial developers & GCs — commercial developments where one civil bid, one schedule, and one accountable contractor simplify everything between land purchase and vertical start, with one billing and closeout chain instead of five.
Data center builders — data center sites compress enormous civil scope into unforgiving schedules, where a single mobilization gap between trades can push energization dates. Turnkey collapses the civil critical path into one contractor's calendar.
Wind & solar teams — renewable energy projects spread roads, pads, and drainage across big acreage, where coordinating separate civil subs across that footprint is a full-time problem turnkey removes. Roads, crane pads, and drainage stay sequenced as one program across the whole footprint.
Energy infrastructure teams — energy infrastructure sites in remote counties, where every additional contractor is another remote mobilization and another interface to manage from a distance. Fewer mobilizations to a far county is a direct saving before any schedule benefit is counted.
Turnkey Site Development FAQ
The questions below come up in almost every turnkey conversation — bring the rest to project review. Short answers here; longer ones on the phone with your drawings open.
What does "turnkey" actually cover — and do we need it?
Turnkey means the civil scopes that touch each other are delivered by one contractor under one contract: clearing, earthwork, stabilization, utilities, drainage, pads, roads, and concrete, in whatever combination the site requires. You need it in proportion to how much interface risk your project carries — a tight schedule, a remote site, expansive soils, or a civil package that would otherwise split across four or five trades are all signals that single-source delivery will pay for itself in sequencing alone. A simple site with one dominant scope may genuinely not need it, and we will say so. The practical test: count the contractors your civil scope currently requires, then count the interfaces between them — each interface is a schedule and responsibility risk you are presently self-managing.
How do you manage the interfaces between scopes?
By owning both sides of each one. Grade handoffs are surveyed and documented once, against one control network. Utility crossings are trenched before stabilization so treated subgrade is never cut open. Trench backfill under future slabs is compacted by the same company that will pour over it. Erosion controls are maintained continuously across phases rather than reinstalled per trade. And one superintendent owns the calendar, so the day a stage finishes, the next crew's mobilization is already scheduled — because it is our crew. None of this is heroic coordination; it is simply what sequencing looks like when the handoffs are internal.
Who sets the specifications, and who verifies the work?
The project's engineer of record and geotechnical engineer set the design and acceptance criteria — grades, compaction requirements, treatment rates, mix designs — and the project's third-party testing laboratory verifies each stage: density and moisture on earthwork and stabilization, materials testing on concrete. TerraTek executes to those criteria; we do not self-certify our own work. Permits and inspection logistics vary by project and contract structure, and responsibilities are defined explicitly during project review so nothing lives in an assumption. That separation is deliberate and we prefer it — independent verification is what makes a stage handoff worth relying on.
Do we have to buy the full package?
No. Every scope in the sequence is also available stand-alone — many clients start with a single scope like stabilization or a pad and expand from there once the sequencing benefit is visible on their own schedule. The package flexes in the other direction too: if the municipality is bringing the utilities, turnkey simply means everything else. Bid it the way your project is structured today; the package can grow at the next phase.
Where does TerraTek take on turnkey work?
Anywhere in Texas. We are based in San Angelo and run full civil packages statewide — the delivery model actually favors distant sites, because one contractor mobilizing to a remote county beats five contractors doing it in series. That reach includes the Concho Valley and Permian Basin markets closest to our base, and commercial growth corridors across the state.
How do we bid a turnkey package — and when should TerraTek get involved?
Send the civil sheets, the geotechnical report, or even a concept plan through our project review page and we will map the scopes and flag the sequencing risks. Ideally that happens during design or preconstruction: early civil input catches utility conflicts, drainage assumptions, and stabilization depths while they are still cheap to fix on paper. If the project is already bidding, a complete civil package prices cleanly against the sum of the separate trades — and the comparison usually makes the interface cost visible for the first time. Either way, the deliverable is the same: a mapped civil scope, flagged risks, and a number you can level with confidence.
Scope & Responsibility
Civil design, permitting strategy, and acceptance criteria belong to the project's engineer of record and geotechnical engineer, and stage-by-stage verification — density, moisture, and concrete testing — is performed by the project's third-party testing laboratory. TerraTek's role is execution: self-performing and sequencing the civil scopes from clearing through concrete to those specifications, under one contract and one schedule.
