S3E is a multidisciplinary engineering office specialized in building design. To do this, S3E has acquired skills tested and confirmed in all areas related to the design and construction of buildings according to the rules in force in respect of sustainable development. We bring expertise and know-how to meet the requirements of our customers.

Reinforced concrete.

We assure Diagnostics - Expertise - feasibility. Our teams are always looking to develop and propose winning solutions. In design phase, with the architect, they will explore all possible - new materials, reinforced concrete, prestressed concrete, prefabrication, - to meet the party's architectural structure. In implementation phase, now, the search for alternatives, solutions, alternative techniques can increase efficiency on site and optimize costs.


Structures and structural steel.

Our engineering department will determine using powerful computational software (Robobat) the technical solution best suited to your project (technical, price, time).


We offer benefits VRD project management, assistance in project contracting and topographic services (surveys, locations, measurements). We take into account in the projects all elements such as respect of its design, integration into the urban landscape, user safety, environmental aspects, quality of life, performance and high-tech works and concern for sustainability of the works.


Telephony, computer networks, TV, Video Surveillance.

We can help you with the choice of the architecture of your IT infrastructure to the physical installation of the materials provided.

After the networking, we follow up and maintenance of your facilities through a contract tailored to your needs and your constraints.

Renewable energies.

S3E works with project owners and contractors for defining the energy strategy of a building or complex of buildings. We carry out actions of energy management and realize the implementation of renewable energies most suited to the needs of buildings.

Our approach is based on the needs analysis of a site, the control of its energy consumption by changing its operating mode and incorporating a maximum of bioclimatic solutions and setting the renewable energy solutions that can cover at these needs more energy.
