Survey and civil engineering built on measured reality, not assumption.
TDR Engineering combines land surveying, civil engineering and 3D laser scanning so your project starts from a complete, measured record of existing conditions — with fast turnaround and pricing that competes with conventional survey work.
- 3D scanning
- Included in applicable survey workflows
- Fast turnaround
- Scheduled to your submittal dates
- CAD, Revit & BIM
- Delivered in your team's format
Why TDR is different
One firm for the survey, the engineering, and the reality capture behind both.
Most projects run survey, civil engineering and scanning through three separate vendors, each working from a different version of the site. TDR performs all three, from the same measured data, on the same schedule.
That single source of truth is what makes fast turnaround and competitive pricing possible without cutting the level of detail your design team actually needs.
- 3D scanning integrated into applicable survey workflows, not sold as a premium add-on
- Deliverables in the CAD, Revit or BIM format your team already works in
- Existing conditions measured rather than interpolated between spot shots
- Survey, civil engineering and scanning coordinated by one firm
- Turnaround scheduled around your plan-check and design deadlines
- Pricing that competes with conventional survey services
The TDR difference
Does your survey look like this?
A conventional survey records a limited number of individually measured points, and everything between them is interpolated. A TDR survey captures existing conditions with 3D scanning, so what you design against is measured rather than assumed. Drag the divider to compare.
Greater field detail
High-density capture records the site as it is, including the conditions nobody thought to ask for.
Reduced field risk
Fewer missed conditions, fewer return trips, and fewer surprises discovered after design is underway.
Better documentation
Architects, engineers, contractors and owners all work from the same measured record of the site.
TDR integrates 3D scanning into applicable survey workflows rather than treating it as a premium add-on — which is why TDR deliverables generally carry more measured detail at pricing that competes with conventional survey services.
How TDR scansServices
What TDR does
Land surveying, civil engineering and 3D reality capture — delivered together or independently, depending on what your project needs.
Land Surveying
Boundary, architectural, topographic, ALTA, construction and as-built surveying performed with current field technology.
Architectural / Topographic Survey
Existing-conditions surveys built for architects and designers, with the detail needed to start design immediately.
Learn moreBoundary Survey
Record research, monument recovery and field measurement to establish where your property lines actually are.
Learn moreALTA / NSPS Land Title Survey
Title-grade surveys prepared to the ALTA/NSPS standard for commercial transactions and lender requirements.
Learn moreConstruction Staking
Field layout that puts the approved plans on the ground for grading, utilities, foundations and improvements.
Learn moreCivil Engineering
Grading, drainage, hydrology and site development engineering, from feasibility through construction support.
Grading Design
Grading and earthwork design that balances site constraints, drainage and cost.
Learn moreDrainage Design
Site drainage, storm drain and water-quality design that satisfies agency review.
Learn moreHydrology & Hydraulics
Runoff analysis, hydraulic modeling and the reports that support drainage approvals.
Learn moreSite Development
Full civil site design from feasibility and entitlement through permit-ready plans.
Learn more3D Scanning & Reality Capture
LiDAR and reality capture that documents existing conditions in far greater detail than a conventional field survey.
Architectural Scanning
Millimeter-level capture of buildings and interiors for renovation, addition and adaptive-reuse design.
Learn moreLiDAR
Laser-based measurement that records millions of precise points per scan setup.
Learn moreScan-to-CAD
Point-cloud data converted into clean, usable 2D and 3D CAD deliverables.
Learn moreScan-to-BIM / Revit
Intelligent Revit models built from scan data at the level of development you require.
Learn moreWhy TDR
Technology, speed, quality, and pricing that competes.
The four things clients tell us matter most — and how TDR delivers each one.
Latest technology
LiDAR and reality capture are standard tools in TDR's applicable workflows, not a specialty service quoted separately.
Fast turnaround
Scanning compresses field time, and schedules are built around your submittal and design deadlines rather than ours.
Exceptional detail
Deliverables reflect measured conditions across the whole site, not a scatter of individually shot points.
Competitive pricing
Integrated survey, engineering and scanning removes the coordination overhead that multiple vendors add to a project.
Technology in the field
What reality capture looks like on a TDR project
From field capture through registered point cloud to the CAD or Revit deliverable your team designs in.
LiDAR in the field
Scanner setups are placed to cover the site completely and tied to survey control, so the data is coordinated, not just visually stitched.
Point cloud
Individual scans are registered into a single dense, measurable dataset covering the ground, structures and surrounding conditions.
CAD, Revit & BIM
The cloud becomes the deliverable your team works in — drafted CAD, an intelligent Revit model, or both, in your format.
Who TDR works with
Industries and professionals served
TDR works directly with owners and just as often alongside the professionals they hire. If you refer a client to TDR, we track that relationship — and we say thank you.
Request a proposal
No account. No login. Just tell us about the project.
Give us the property, the services you think you need and your timeframe. If you are not sure which survey your project requires, describe the situation and TDR will recommend the right scope rather than the largest one.
What to have ready
- Project address, and the APN if you have it
- What you are trying to accomplish
- Your timeframe or submittal deadline
- Any existing survey, title report or drawings
- Who referred you, if a professional sent you our way
