About us

Since 70’s, CESAR grows and develops with the skills and expertise of researchers of the French Public Works administration. This high and valid scientific content is offered to professionals with a highly user-friendly graphical interface. Thus CESAR is destined to become your current tool for engineering works.

GUI development / Marketing / Distribution

Created in 1986, itech is an IT services company playing a major role in the domain of software marketing for Construction and Civil Engineering.

itech pursues its main line of business in the design, development and distribution of structural computation software packages for use in the sectors of construction, civil, roads and mechanical engineering.


Scientific development / Validation

Former LCPC until 2011, IFSTTAR is an organisation of reference in the international arena

IFSTTAR’s role is to carry out and commission, direct, lead and appraise research, development and innovation in the areas of urban engineering, civil engineering, and construction materials, natural hazards

Software training

itech provides well established courses in Computational Methods for a good use of CESAR software. These courses are of 3 types.

Several companies may attend these courses.
Several programs are proposed

  • Geotechnical Engineering (2D models)
  • Geotechnical Engineering (3D models)
  • Tunnel analysis (2D and 3D models)

Other trainings can be tailored (structural analysis, concrete at early age).

The content of the training is discussed and established in function of the user’s profile. This king of course has the advantage to fit the customer needs.
This training can also be a good pre-sale introduction to CESAR software.

itech has chosen the Teamviewer tools for a flexible and quick assistance to the user. The advantages of these tools are a flexible choice in terms of content and date. Thus is it easy to schedule a training program, tailored and scalable (half-day training as example). These tools also overcome distances and borders. A simple broadband internet connection is required.

In addition to its array of activities in the area of technical software design, development and marketing, itech and IFSTTAR offer customers the services of an in-house team capable of conducting specialized studies or expert evaluations within a variety of fields.

  • Deformation and stability analysis with incorporation of construction phasing
  • Capacity to include non-linear behaviour (plasticity, contact, etc.)
  • Analysis of dynamic behaviour, seismic behaviour, etc.
  • Porous media flow problems
  • Capacity to solve coupled problems (consolidation, thermo-poro-mechanical coupling, etc.)
  • Temperature field and stress field computations during concrete setting.

Our consulting tasks cover the full aspects of the analysis or can be reduced to the modelling (geometry + mesh) of the customer project.

Benefiting from its 20 years of experience in this field, itech is involved in developing "customized software products" designed to enhance client productivity within a specific field.
"From scratch" or "reengineering"
"Customized" software typically stems from two sources:

  • software developed "from scratch" on the basis of a set of specifications drawn up by the client,
  • software derived from technical developments achieved within the client organization yet which fail to (or no longer) meet desired quality-related standards (known as "reengineering").
