Services
Survey, civil engineering and reality capture — from one firm.
TDR's service architecture covers the full path from measuring what exists today to engineering what gets built next.
01
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 moreAs-Built Survey
Verification of what was actually constructed, for agency close-out, certification and record documentation.
Learn moreSubdivision & Mapping
Parcel maps, tract maps, lot line adjustments and the survey work that supports entitlement.
Learn moreSpecialized Surveys
Elevation certificates, easement exhibits, encroachment studies and other targeted survey products.
Learn more02
Civil 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 moreHillside Development
Engineering for constrained hillside sites where topography drives the design.
Learn moreInfrastructure
Street, utility and public improvement design for private and public projects.
Learn moreConstruction Support
Engineering support during construction: RFIs, revisions, field changes and close-out.
Learn more03
3D 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 moreRevit / BIM Services
BIM coordination, model maintenance and existing-condition models for design teams.
Learn moreIndustrial Scanning
Plant, process and equipment capture where clearances and tie-ins have to be exact.
Learn moreStructural Documentation
Measured documentation of structural framing, deflection and existing conditions.
Learn moreFloor Flatness & Surface Analysis
Full-coverage floor flatness and levelness analysis instead of spot elevations.
Learn moreLarge Facility Capture
Registered capture of campuses, warehouses and multi-building facilities.
Learn moreExisting Conditions Documentation
A permanent, measurable record of a site or building before work begins.
