General Resources and New Works Manager

At the project kick-off, the definition of the roadmap was very clear and easy for us to understand. The project design meetings followed one another smoothly, allowing for a rapid start to the construction phase.

Once the works began, everything progressed naturally, reflecting the expertise of the ATIXIS teams. I particularly appreciated the project ‘warning’ alerts and the energy the teams put into pushing us to make key decisions.

In summary, I am extremely proud to have been able to manage this project remotely, thanks to professional and reliable partners. The financial goals were met, and the deadlines were respected.

Frequently asked questions

What are ATIXIS’s areas of expertise?

ATIXIS is a multidisciplinary engineering and project management company. Its expertise covers the entire lifecycle of a construction or renovation project:

  • Owner’s representative: supporting the project owner in defining and managing their project: feasibility, scheduling, project management during the design and construction phases, monitoring of Quality, Cost, Schedule, and Risk
  • Project Management (PM): Coordination of the project management team (architect and engineering firms), oversight of architectural and technical design, coordination of engineering studies, and construction supervision
  • MEP Engineering: Design and construction supervision of heating, ventilation, and air conditioning (HVAC) systems, electrical systems, plumbing, sprinkler systems, and fire safety systems
  • Structural Engineering: Design and construction supervision for reinforced concrete, wood, and metal structures, for new buildings, renovations, and civil engineering structures
  • Design & Build: Design and construction are handled by a single team, from start to finish
  • Environment & Sustainability: Environmental planning, energy performance, certification, reuse, and the circular economy, through our TERAO division
  • Digital: Digital transformation of construction projects, collaborative tools, and data management solutions, through our Blookod division

What is the difference between an Owner’s representative and a Project Management Team in a construction or renovation project?

These roles are complementary and cannot be combined (one cannot be both judge and jury):

  • The Owner’s representative represents the client. It supports the project owner in decision-making and project management. The Owner’s representative guides, coordinates, and supervises service providers (Project Management, contractors, etc.)
  • The Project Management is responsible for the design and technical oversight of the project’s execution. It produces the design documents (preliminary design, detailed design, tender documents), coordinates the various design firms, and prepares the contractor selection process
  • Execution Project Management becomes involved once construction has begun. It oversees the execution of the work, ensures that the construction complies with the design documents, coordinates contractors through Scheduling, Management and Coordination, and manages the final acceptance of the project

ATIXIS can assist with these various tasks.

What is Design & Build, and in what situations is this approach recommended?

Design & Build is a contracting model in which a single service provider, the general contractor, is responsible for both the design and construction of the project, unlike traditional contracts where these two phases are separate.

This approach is particularly recommended for:

  • Projects with tight deadlines requiring a quick start
  • Commercial fit-outs and office renovations
  • Projects requiring significant design flexibility during construction
  • Project owners seeking to limit the risk of budget overruns

ATIXIS offers an integrated Design & Build service, from technical design through to construction supervision, ensuring control over schedules and costs.

What types of buildings and sectors require specialized technical engineering?

Certain buildings impose very high technical requirements that necessitate specialized engineering, far beyond standard construction practices. Among the most demanding sectors are:

  • Office & Corporate Buildings: offices, corporate headquarters, and corporate campuses, with significant challenges regarding space flexibility, energy efficiency, and occupant comfort
  • Healthcare: hospitals, clinics, and nursing homes, subject to strict regulations (hygiene, fire safety, business continuity)
  • Data centers: buildings with very high technical density requiring exceptional engineering for mechanical, electrical, and structural systems
  • Education: schools, universities, and campuses, requiring engineering tailored to intensive use, accessibility standards, and energy performance challenges
  • Industry & Logistics: warehouses, production facilities, and logistics hubs with constraints regarding loads, ventilation, and industrial safety
  • Energy: nuclear power plants, gas, thermal, and renewable energy facilities, subject to the strictest regulations in the market
  • Transportation & Infrastructure: train stations, airports, civil engineering structures, and mobility facilities, combining exceptional structural, fluid, and personal safety requirements
  • Sports & Recreation: stadiums, sports complexes, swimming pools, and amusement parks, with specific requirements regarding acoustics, ventilation of large spaces, and public access

ATIXIS has engineers specializing in each of these sectors, ensuring a technical solution tailored to the specific
requirements of each type of project.

Why should you entrust your construction or renovation project to a multidisciplinary engineering firm rather than to several specialized contractors?

Working with a multidisciplinary engineering company like ATIXIS offers several key advantages over coordinating multiple specialized firms:

  • A single point of contact responsible for the overall consistency of the project
  • Synergy between areas of expertise that prevents inconsistencies between technical disciplines
  • Optimized management of costs and schedules thanks to a cross-functional perspective
  • Enhanced responsiveness to address on-site contingencies without delays caused by external coordination
  • Continuity of teams from design through to handover

What sets ATIXIS apart from its competitors?

The market for engineering and construction project management in France includes a wide range of players, from large international groups to specialized firms. Several factors set ATIXIS apart in this landscape:

  • A human-scale approach that ensures responsiveness: whereas large groups like Artelia, Egis, or Ingerop rely on extensive organizational structures with sometimes cumbersome processes, ATIXIS offers direct access to the engineers in charge of the project, rapid decision-making, and personalized support at every stage
  • Comprehensive multidisciplinary expertise under one roof: Owner’s representative, Project Management, MEP Engineering, Structural Engineering, Design & Build – all expertise is in-house. This prevents information loss between service providers and ensures end-to-end technical consistency, without costly external coordination
  • Specialized sector expertise: ATIXIS does not position itself as a generalist in construction. Its teams specialize in demanding project types: hospitality, data centers, healthcare, energy-efficient buildings, public facilities, etc., where technical expertise takes precedence over volume

It is this positioning that makes ATIXIS a natural partner for discerning project owners who expect both technical rigor and a personal commitment to their projects.

What does a project with ATIXIS look like, from the initial meeting to delivery?

Every project is unique, and ATIXIS’s services are tailored accordingly. Some clients engage us from the very beginning, while others only for design or construction supervision. Regardless of the scope of the project, we structure our work around key milestones that ensure clarity, control, and continuity:

  1. Initial contact and scoping: From the very first discussion, the ATIXIS teams take the time to understand the context, challenges, and specific constraints of the project (budget, deadlines, technical requirements, stakeholders). No project begins without a thorough understanding of the actual needs.
  2. The preliminary phase and feasibility study: ATIXIS supports the project owner in defining the scope of work, analyzing technical options, and assessing risks. This phase lays a solid foundation before any work begins.
  3. Design studies: Engineers produce Technical studies in coordination with the architect and other stakeholders to ensure the project’s overall coherence.
  4. Bid evaluation and contractor selection: ATIXIS assists with bid analysis, negotiation, and the finalization of construction contracts to secure contractual commitments.
  5. Site supervision and final inspection: The teams oversee or manage the construction work, verify compliance, coordinate with the project manager, and oversee the final inspection until all issues are resolved.
