Quadri (Novapoint)

AutoCAD-based civil engineering design and documentation platform for grading/surfaces, road and rail corridor modeling, pipe network hydraulics, and survey -- the civil-engineering flagship that turns conceptual InfraWorks models into construction-ready plan/profile sheets and quantity takeoffs.

Parametric BIM platform for advanced infrastructure design to build workflows -- extends Allplan Ultimate with integrated bridge structural analysis (AASHTO LRFD and Eurocode with national annexes), code-based reinforcement design and checking, parametric road/alignment modeling, 4D construction sequencing, and prestressing tendon modeling; supports all relevant file interfaces (IFC, BCF, LandXML, DWG, DGN, RVT, 3DM) plus Python API and Visual Scripting for automated workflows; part of the Nemetschek Group, with transparent published subscription pricing on the Allplan e-store.

Early-stage conceptual infrastructure design tool that builds a GIS-rich 3D context model (terrain, imagery, existing utilities) for rapid road, bridge, rail, and drainage concept design and stakeholder visualization before detailed design moves into Civil 3D or Revit.

Standard airport pavement thickness design software developed and distributed free by the U.S. Federal Aviation Administration (FAA) -- implements the FAA AC 150/5320-6G pavement design methodology using layered elastic analysis and the ACR/PCR pavement-strength reporting method; the mandatory tool for any U.S. airport pavement engineer working on FAA-funded airport projects, with companion backcalculation (BAKFAA) and runway-exit-design (REDIM) software.
