Engineering

Fixed-fee engineering services delivered in 10 days or less, at-scale.

Wait. How can anyone promise fixed fees with a guaranteed speed-of-delivery with engineering? Nobody can, except Terrane.

We own the surveying and orchestration to couple the expertise of these disciplines at-scale. The result is more certainty for you and clarity on the costs of your projects.

Surveying + Engineering: One call does it all.

Fixed-Fees. Guaranteed Speed

Let's Talk

By owning the survey, we control the speed of engineering. Highly orchestrated workflows that compress schedules, reduce downtime, and keep your project on target and within budget.

What about rates? It’s industry standard to bill by the hour. Costs depend on how long the work takes. You don’t know the bill until after the job is over.

We don’t operate that way. Our focus is on you and your project. We give you a fixed, upfront fee that’s priced to the scope of the deliverable. A predictable cost structure you can bank on.

Feasibility to Approval

First, we survey. Second, we deliver engineering. Third, we manage the permitting process through approval. So rather than coordinating multiple firms, you work with one integrated team from start to finish.

Our engineering services include:

Feasibility Studies
Site grading and drainage design
Stormwater and erosion control plans
Utility layout and coordination
Access and roadway design
Earthwork calculations
Land use and jurisdictional coordination
Permit preparation and agency coordination
Construction documents for permitting and construction

Where needed, work is prepared under the oversight of licensed Professional Engineers.

Time is the Measure

Problems we’re solving

When surveying and engineering operate independently, assumptions replace verified conditions. Every handoff introduces delay, rework, and uncertainty. Terrane eliminates those gaps by engineering directly from current, measured field data.

Disciplines working together

Surveying and engineering operate as a single workflow. Verified field data moves directly into design without translation, reinterpretation, or delay. The result is fewer revisions, fewer change orders, shorter schedules, and permit-ready deliverables—fast.

When to engage

Bring Terrane in when your project requires engineered plans for permitting or construction. If surveying alone is sufficient, we’ll tell you. If engineering is required, we’ll define the fixed-fee scope with a guaranteed schedule before work begins.

Boundary of commitment

Engineering is performed under licensed oversight where required. We define clear responsibilities, clear deliverables, and clear accountability from the outset, so every project proceeds with confidence and without ambiguity.
