The Agency

A multi-disciplinary team

C&E is an engineering and architecture firm with a multidisciplinary team of architects and engineers based in Paris and Shanghai. The company currently employs around 30 people and has a dozen partners. C&E A+I handles some fifty projects every year, in the fields of housing and facilities, footbridges, earthquake reinforcement, Ultra High Performance Fiber Concrete engineering, temporary or artistic installations, reuse and bio-sourced materials

Architecture and engineering

Sustainable construction and the transformation of urban infrastructures and buildings play an essential role in society's quest to reduce the ecological footprint of construction and overall societal sustainability. Design choices, including strategies for reducing, reusing or recycling materials in the design and planning processes, have a major impact on overall project design strategies.

Success in this field requires in-depth knowledge of design, technological solutions and construction processes. At C&E Architecture and Engineering, we are curious and open to developments in our field, ready to take on new subjects, ready to question our certainties and critically re-examine our know-how.

Areas of intervention

Housing and equipment

A new operational practice has emerged: the valorisation of the local rootedness of architectural projects from the moment they are realised in close collaboration with clients, suppliers and local contexts that allow the technological and production know-how to be fed. At a time of hyper-normalisation and hyper-regularisation, it is the singular, the local that emerges. This hypothesis gives rise to a new methodological practice: hybridization, which goes beyond simple one-off adaptation.We note that it functions on the principle of transformation, or even the genesis of new constructive systems. Hybridization emerges from the interaction between different systems, different contexts, different labour markets and skill structures, different infrastructures. Hybridization of technical solutions characterizes the production of architectural equipment and housing today.

Crossings

The design of a bridge or a footbridge has its origins in a fundamental architectural act: lifting a weight. There is no architecture without weightlessness. The geometry and static layout of the crossing are an expression of weightlessness. But this is not the only objective of the crossing. It's also about being able to contain a large space, the landscape that surrounds the project.

Ultra high performance concrete

Ultra-high-performance fiber-reinforced concrete (UHPC) is a new family of materials. They offer exceptional mechanical properties, durability, abrasion resistance, resistance to chemical aggression and weathering (freeze-thaw, sea water, etc.).

Over the past twenty years or so, C&E has acquired a wealth of experience in France and abroad. This development led to the creation of C&E Ingénierie Shanghai, headed by engineer Yanni Zhao.

Seismic reinforcements

Many buildings have been constructed without taking seismic risk into account. In most cases, these are older buildings or were built before the existence of a body of recommendations. Such buildings can be extremely vulnerable to earthquakes. In these conditions, it is clear that the examination of the conditions that "aggravate" vulnerability must be accompanied by proposals for work to improve structural vulnerability. The aim of our work, carried out in collaboration with Professor Victor Davidovici, Honorary President of the AFPS, is to develop a generic approach aimed at improving methods for analyzing the vulnerability of fragile constructions and possible strengthening methods.

Projects on existing buildings

SWOT (Strengths - Weaknesses - Opportunities - Threats) or MOFF (Threats - Opportunities - Strengths - Weaknesses) is a practical tool for strategic diagnosis. It has the advantage of synthesizing the strengths and weaknesses of a situation through a qualitative analysis of the opportunities and threats generated by its environment. Questioning the rehabilitation of existing buildings from this angle enables us to take positive advantage of most of the project situations we encounter. For each project, it's a question of determining the environment in which we're working, and developing a unique approach based on the existing state to define the possible and necessary modes of improvement, reinforcement or repair. For us, it's a question of finding the dormant potential of these architectures first and foremost.

Hybrid structural system

Until the Second World War, the choice of materials and construction methods for traditional buildings were defined a priori, by descriptive specifications that constituted standard solutions. Since the end of the Second World War, the notion of "performance to be achieved" has gradually replaced the description of standard solutions. Today, the question of performance has become omnipresent, particularly in the context of climate change. Against this backdrop, an operational practice has emerged: the implementation of hybrid building systems based on the combination of heterogeneous building systems, with no unifying transverse normative frame of reference. This is the context in which we need to build today.

Matériaux géo et biosourcés - Réemploi

Les matériaux géo et biosourcés ainsi que ceux issus du réemploi nous obligent à ré interroger les questions de durabilité, de maintenance et apprendre comment associer qualité et fragilité relative, performance et limite d’utilisation raisonnable. Ils réinterrogent aussi la responsabilité de l’ensemble des acteurs de l’acte de construire et demande une connaissance encore plus précise du cadre réglementaire général afin de comprendre comment les mettre en œuvre.

See projects

Temporary and artistic installation

Moving in and out of a public space. Set up and dismantle what has been set up. Balancing without using foundations, stabilizing against tipping and sliding, weighting down while remaining light. These questions take us back to the foundations of our work in the service of the community.

Glass roof and envelopes

La conception de l’enveloppe peut être ramenée aux problématiques de l’étanchéité à l’eau et à l’air, de la lumière, de l’acoustique, de la sécurité incendie, de la vapeur d’eau et finalement de la structure de surface qui permet d’unir ces composants en un seul système. Si ces questions sont génériques et récurrentes il s’agit pour chaque projet de trouver comment les résoudre au travers d’une écriture architecturale singulière.

Research & Development

The aim of our R&D work is to contribute to the development of constructive systems in Architecture. Today, this mainly concerns seismic reinforcement, ultra-high- performance fiber-reinforced concrete and multifunctional hybrid envelopes.
