AGTEK Gradework 4D 2026 v1.12.5.6 – Complete Earthwork Takeoff and Construction Modeling Solution

AGTEK Gradework4D 2026 v1.12.5.6 is a comprehensive takeoff and modeling solution that streamlines the construction lifecycle from bidding through completion . The software analyzes data from PDF, CAD, or manual entry to create accurate bids and manage sites efficiently .

The “4D” capability adds a time dimension, allowing users to monitor construction progress over time, ensuring work proceeds according to schedule . The software creates a digital representation of the site including existing ground surface, proposed changes, and strata layers beneath the surface .

Version 1.12 introduced several powerful enhancements, including the new ESX file format (replacing ESW and ESZ formats) and improved features for PDF management, slope maps, and phased reporting.

Primary Users

AGTEK Gradework4D is designed for civil engineers, construction estimators, project managers, and sitework contractors who need accurate earthwork calculations and project modeling. It serves professionals who:

  • Perform earthwork takeoff and bidding for site development, road, and infrastructure projects

  • Create 3D site models from PDF, CAD, or survey data for accurate volume calculations

  • Analyze strata layers and underground conditions for trench and excavation planning 

  • Generate machine control models for GPS-guided excavation equipment 

  • Process drone imagery and point clouds to track earthwork progress and document as-built conditions
