Benefits 1•2•Build

Without any effort

Within 1•2•Build’s user-friendly structural engineering design environment, you simply draw a beam of frame structure on the screen.  Next, the model is completed graphically and interactively with boundary conditions, permanent loads and variable loads. 

The most economic design

1•2•Build is the perfect tool for your day-to-day design analyses and for the estimation of material quantities.  At any time, it will propose you the most optimal solution for your design projects.

1•2•Build offers structural design capabilities for different materials:

  • reinforced concrete, with immediate access to the optimal dimensions of structural elements and related reinforcement quantities.
  • steel, with automated selection of the cross-section, within the selected section class (IPE, HEA, HEB, HEM, L, ...), structural steel software that best suits your design requirements in terms of strength, stability and maximum deformation.
  • timber, with automatic sizing of beams as a function of the selected timber class. Of course, stresses and deflections can be verified at any time thanks to clear color diagrams.  

A profitable investment

1•2•Build is a complete solution which offers you (for a fixed price) all necessary functionality for an optimal structural design, up to the creation of a concise and readable analysis report.

Features 1•2•Build

General features
