Carlson TrenchCarlson Trench

Carlson Trench is for calculations related to installing pipes, sewers, or utility lines. The software calculates the volume of the trench cut, the volume of backfill (excluding the pipe size), and the linear footage of pipe broken down by the pipe material, size, and/or depth.

Carlson Trench is fully integrated with Carlson Civil and Construction, and also Carlson Hydrology to meet the variety of customers’ needs.

Carlson Trench supports AutoCAD® and comes with IntelliCAD® built-in. This is in addition to working on legacy AutoCAD versions.

Developed originally within Takeoff,  Carlson’s popular site estimating and data prep software, Carlson Trench joins with Carlson GeoTech and Carlson CADnet to provide customers the flexibility to obtain just the software they need at an affordable price. The three modules can also be paired with Carlson Construction to form the all new Carlson Takeoff Suite, replacing the non-OEM version of Takeoff. (Note: Carlson Takeoff with built-in AutoCAD remains the same.)

“These modules serve to answer the specific needs of geotechnicians, civil engineers, and construction professionals who may not have required all of  Takeoff’s many capabilities,” says Todd Carlson, product manager for Takeoff.
