Trimble Business Center

By audience

Civil Engineering

• Civil engineers receive existing-ground surfaces and contours built from survey data as the base for site and roadway design.
• Roadway teams review cross-sections, superelevation and alignment templates when a design is converted into a constructible model.

Estimator

• Civil estimators run cut and fill quantity takeoffs from digitized plans and surfaces to price earthwork bids.
• Mass-haul analysis shows haul distances and balance points so estimators can price trucking and borrow or waste.

General Contracting

• Heavy civil contractors digitize PDF plans and build 3D surfaces and corridors that drive machine-controlled dozers and graders.
• Contractors compare as-built survey against design surfaces to track earthwork progress and support pay quantities.

Specialty Contracting

• Earthwork and site subcontractors prepare machine control files and staking data in house instead of buying them from a surveyor.
• Utility and piling crews get utility models and drilling and piling plans prepared for setout in the field.

Surveying/Geomatics

• Surveyors review rod heights and vector quality, then run least squares adjustment and GNSS baseline processing before issuing control.
• Field crews' total station, level, scan and UAV data land in one project, so blunders are fixed without re-exporting.
• Survey teams classify point cloud regions and extract linework and features into CAD for topographic deliverables.
• Surveyors publish large scan and mobile mapping point clouds to Trimble Connect for project teams to view in a browser.

By phase

Design

• Survey teams process topographic, scan and UAV data into the existing-conditions surfaces and linework designers start from.
• GIS-bound survey features are exchanged with Esri ArcGIS for design and asset mapping.

Pre-Construction

• Estimators take off earthwork quantities and run mass-haul analysis while pricing a civil bid.
• Contractors convert design files into machine control models and stakeout data before crews mobilize.

Construction

• Field GNSS, total station and machine data are processed daily to check grade and update progress quantities.
• Monitoring data from instruments is compared against design to report deformation during construction.
• Survey crews record as-builts, including tunnel setout and as-built models on underground work.
