Carlson Takeoff Suite Earthwork Estimating and Machine Control Software

Carlson Takeoff Suite for earthwork estimating and construction data preparation

Carlson Takeoff Suite is designed for construction professionals who need to turn plans and design data into reliable quantities, 3D surfaces and field-ready construction information. It brings estimating and data preparation into a familiar CAD environment, allowing contractors, estimators, surveyors and civil engineering teams to work from paper plans, PDF files or electronic CAD drawings without having to rebuild every project in a separate estimating system.

The suite combines Carlson Construction, Carlson CADnet, Carlson Trench and Carlson GeoTech. Together these modules cover the workflow from initial plan conversion and drawing cleanup through earthwork quantities, roads, utilities and subsurface materials to final data preparation for staking and machine control.

Calculate cut and fill from practical 3D surface models

For earthworks and site development, Carlson Takeoff Suite can create and compare existing and proposed terrain surfaces using triangulated 3D models. This allows users to calculate cut and fill across an entire site or concentrate on selected areas where separate quantities are required.

Estimators can calculate more than a single bulk earthwork figure. The software supports subgrade quantities, topsoil removal and replacement, over-excavation and strata volumes. Shrink and swell factors can also be included where material behaviour needs to be considered. In practical terms, this helps an estimator understand not only how much material must move, but also where different excavation or fill conditions occur across a project.

Cut/fill colour maps, contours, profiles and 3D surface viewing tools provide a visual check before quantities are issued. These tools are useful for finding incorrect elevations, unexpected surface transitions or areas where the proposed model does not match the intended design.

Work directly from PDF plans and CAD drawings

Not every tender arrives as a clean 3D CAD model. Carlson Takeoff Suite is built around that reality. When electronic CAD information is available, the software works directly in a DWG-based environment. Drawing Cleanup tools can help correct common problems such as invalid elevations, broken linework and unwanted drawing information before the model is used for quantities.

When only plans are available, Carlson CADnet provides tools for digitising paper drawings and working from PDF, TIF, JPG and other raster information. PDF linework can be traced into CAD entities, and multiple raster plan sheets can be combined where required. Once the relevant linework and elevations have been created, the same surface and quantity workflow can be used as with an original CAD drawing.

CADnet also supports BIM-oriented workflows, including importing model information such as Revit or IFC data into the CAD environment. This is useful when construction layout or quantity work needs to be coordinated with information supplied by architects or other project partners.

Material and subgrade quantities

Earthwork is only part of a construction estimate. Carlson Construction can also report quantities for defined materials and subgrades. Depending on the item being measured, reports can include volume, area, length or count. This makes the software useful for estimating items such as asphalt, gravel, pavement layers, curb work, select fill and other construction materials that are represented in the design.

Subgrade depths can be used to adjust the proposed design surface vertically, including situations where several material areas overlap or are nested inside one another. Hatching and visual checks make it easier to confirm which material definition applies to each part of the site before the quantities are finalised.

Road and corridor takeoff

Road contractors and civil construction teams can work with centre lines, vertical profiles, design templates and cross-sections. Carlson Takeoff Suite supports cross-section based earthwork calculations, end-area volumes and mass-haul analysis, while RoadNET tools can be used when more detailed road and intersection modelling is required.

This is particularly useful when tender information is supplied as profiles and sections rather than as a finished surface model. The design information can be converted into a usable 3D representation for estimating and later construction data preparation.

Trench pipe and utility quantities

Carlson Trench adds dedicated tools for pipe, trench and manhole work. Users can define trench and pipe information and calculate excavation, backfill and pipe lengths. Pipe quantities can be separated by factors such as size or material, giving utility contractors more useful information than a simple overall trench volume.

Profiles, 3D pipe displays and depth-zone mapping also help check the design before quantities are released. For projects involving sewer, drainage or utility networks, this makes it easier to see where deeper excavation or different trench conditions may affect construction effort and material requirements.

Model rock soil and other subsurface strata

Carlson GeoTech provides the subsurface component of the suite. Borehole or drillhole information can be used to create strata surfaces and model changing ground conditions across the site. These surfaces can then be included in the normal takeoff workflow.

For an estimator, this means excavation can be separated into meaningful material types such as soil and rock rather than being treated as one uniform volume. Strata information can also be used when calculating topsoil removal or over-excavation, helping contractors understand where ground conditions could influence excavation methods and quantities.

Prepare data for staking and machine control

Once a project moves from estimating into construction, the same model can continue to be useful. Carlson Takeoff Suite includes tools for creating points, generating points from drawing entities, dividing points along linework and preparing triangulated surface information for the field.

Machine-control data can be prepared for widely used systems including Topcon, Trimble and Leica workflows. Carlson Construction also provides formats used by Carlson Grade and other construction systems. This allows an office data-prep technician or surveyor to take the design information used during estimating and convert it into a controlled surface or layout dataset for field crews and machine operators.

Keeping estimating and field-data preparation in the same CAD-based environment can also reduce the need to recreate the design in another package after the project is awarded.

Who is Carlson Takeoff Suite for?

Carlson Takeoff Suite is particularly suited to earthmoving and grading contractors, construction estimators, civil contractors, road builders, utility and trenching contractors, survey and construction-layout teams, civil engineers and specialists responsible for machine-control data preparation.

It is also useful for companies receiving projects in many different formats. A contractor may receive a DWG on one job, PDF tender drawings on another and profile or cross-section data on the next. Carlson Takeoff Suite provides tools for turning these different source files into a consistent CAD and 3D surface workflow.

IntelliCAD and AutoCAD workflow

The Takeoff Suite can operate with the included IntelliCAD environment, so a separate AutoCAD licence is not required for the IntelliCAD workflow. Organisations that already use a supported full AutoCAD installation can also run Carlson Takeoff Suite in that environment. Working directly with common DWG-based project information is especially useful when exchanging drawings with engineers, surveyors and other construction partners.

Choosing Carlson Takeoff Suite from Global GPS Systems

Global GPS Systems can help determine whether Carlson Takeoff Suite matches your estimating and construction data-preparation workflow, including the type of design files you normally receive and the surveying or machine-control systems used in the field. This is especially relevant for organisations that want their estimating, construction staking and machine-control preparation to use the same underlying project data.

For companies already using Carlson software, the Takeoff Suite can also form part of a wider Carlson workflow and can integrate with products such as Carlson Civil and Carlson Hydrology where those additional modules are required.
