Presentation of the agency
C&E is an engineering and architecture firm with a multidisciplinary team of architects and engineers. The firm currently has some twenty employees and about ten partners who are asked to discuss design developments. We handle around fifty projects every year in such fields as housing and facilities, bridges and footbridges, earthquake-reinforcements structural design, Ultra High-Performance Fibre-Reinforced concrete design, temporary installations and finally sustainability.
Our convictions and commitment to Engineering and Architecture design process have led us to be open to all type of materials, construction processes and programs and this has enabled us to continually renew and expand our skills and design capabilities.
Activities and trades
A new operational practice has emerged: the valorization of the local roots of architectural projects from the moment they are realized in close collaboration with customers, suppliers and local contexts that allow to feed technological know-how. and production. At a time of hyper-normalization and hyper-regulation, it is the singular, the local that emerges. From this hypothesis is born a new methodological practice: hybridization that goes beyond mere ad hoc adaptation.
It can be seen that it operates on the principle of the transformation or even the genesis of new constructive systems. Hybridization emerges from the interaction between different systems, different contexts, different labor markets and skill structures, different infrastructures. Hybridization of technical solutions today characterizes the production of equipment and housing in architecture.
The design of a crossing has as its origin a fundamental architectural act: to lift a weight. There is no architecture without weightlessness. The geometry and static schema of the bridge are an expression of weightlessness. But this is not the only goal of the crossing.
It is also about being able to contain a large space, the surrounding landscape. It is a peculiarity of the crossing work: when one crosses the void contained by the deck, then establishes a singular relationship with the environment …
Ultra High Performance Fiber Concrete (UHPC) is a new family of materials. They have exceptional mechanical and durability characteristics, resistance to abrasion, resistance to chemical attack or bad weather (freeze-thaw, seawater, etc …).
For fifteen years now, in partnership with Lafarge In particular, Sofistik, the C & E software developer, has contributed its expertise, through multiple experiences at all scales, to a set of projects made from Ultra High Performance organic or metallic fiber concrete.
Many buildings were built without taking into account the seismic risk. These are mostly old buildings or made prior to the existence of a corpus of recommendations. Such buildings may be extremely vulnerable to the earthquake. In these conditions it is understood that the examination of the conditions of “aggravation” of the vulnerability must be accompanied by proposals for works of improvement of this structural vulnerability.
Most of our work, done in collaboration with Professor Victor Davidovici, aims to develop a generic approach to improve the methods of vulnerability analysis of fragile constructions and modes of reinforcement possible.
With the work of art, the work of the Engineer is erased. If it exists it is to silently accompany the search for stability, resistance that allows its implementation. The technical answer is in the work of art and not outside. The artist, or the scenographer, often has in him a vision of the stability of his work.
It is therefore necessary to listen to it and to seek what could be the good interpretation, the good technique of the object. For each work, on each site, there are specific constraints that must be understood and internalized so that they serve its material realization.
To fully integrate the reuse of materials, building systems and more generally buildings, it is necessary to organize a form of positive transgression. That is to say being able to consciously derogate from certain rules that could have consequences that are the opposite of those for which they are used, while of course being extremely attentive to the actual risk taking and to their security by the analysis and the diagnosis.
For each project it is a question of determining the regulatory environment in which one fits and to develop a singular reasoning which relies on the existing state to define the modes of improvement, reinforcement or possible repair and necessary.
Study that seeks to check the technical and economic feasibility of the structure and roofing, doors and windows for a project.
Study that seeks to assess the vulnerability of the structure of an existing construction when subject to static or dynamic loads.
Project management assignment
Designing an engineering and architecture project. This assignment can also include site monitoring.
This involves compiling the documents required for the contractor to perform the work
Projects geographical localisation
We currently work in mainland France but also on foreign construction projects. We operate or have operated in America (North American, Canada, Martinique and Haiti), Europe (Switzerland and the U.K.) Africa (Algeria, Gabon, Qatar, Morocco and Tunisia) Asia (South Korea and China).
Prizes and Awards
With our partners, the work of “C&E ingénierie” has been rewarded and awarded in France and abroad.
Professional qualifications have been obtained from the construction industry qualification body OPQIBI (Organisme Professionnel de Qualification de l’Ingénierie Bâtiment Industrie). OPQIBI qualification certificates are officially recognised in the French Public Works Code as proof of the candidates’ abilities (article 45)..
