In French-speaking Switzerland, the roles of the general contractor and the project manager are traditionally presented as distinct. This contractual separation remains relevant in certain contexts, but it no longer always reflects the operational reality of complex renovation projects , particularly in Geneva and the canton of Vaud.
In practice, the success of a project depends less on the strict separation of responsibilities than on the continuity between design, technical feasibility, planning, and execution . It is within this framework that a more integrated model is emerging, designed to address the real complexity of contemporary renovations.

Renovation: a non-linear process by nature
Unlike new construction, a renovation project is rarely fixed from the outset. It is generally:
evolving,
depending on what already exists,
rich in technical interfaces,
sensitive to decisions made during the project.
Design choices influence feasibility.
Feasibility can redefine certain choices.
The execution sometimes reveals constraints that were invisible on the plans.
In this context, the management of works cannot be considered as a simple administrative step downstream of the design.
The limitations of the traditional general contracting model in renovation
The traditional general contracting model is particularly effective when:
The project is fully defined.
The technical decisions have been finalized.
The sequences are stable.
However, in renovation projects, these conditions are rarely met from the outset.
Late adjustments can then generate:
budgetary tensions,
delays,
a loss of clarity for the customer,
increased pressure on design and execution teams.
These limitations are not related to the profession itself, but to the point at which construction expertise intervenes in the process .
Anticipatory corporate involvement as a lever for reliability (ECI)
The company’s early involvement consists of integrating constructive expertise from the planning and feasibility phases , before all decisions are finalized.
In renovation projects in Geneva and Vaud, this approach notably allows for:
to anticipate the constraints of the existing situation,
to structure coherent work sequences,
to make budgets more reliable,
to reduce costly adjustments during the execution phase.
This early involvement does not call into question the role of the architect. It secures the transition between intention and realization .
Value management: deciding better, not deciding less
Value management is not about the systematic reduction of costs.
It involves evaluating each option according to several criteria:
technical performance,
sustainability,
impact on deadlines,
consistency with the architectural intention,
total cost over the life cycle.
Integrated from the early stages of the project, value management enables:
to avoid emergency arbitration,
to maintain the overall coherence of the project,
to strengthen trust between the parties.
It is particularly effective when it is part of a structured pre-construction approach.
Design-assist as a tool for technical collaboration
Design-assist is based on a simple principle: associating technical skills (general contractor, site managers, specialized partners) with the design phases early enough to test the real feasibility of the solutions envisaged.
This approach allows:
to anticipate sensitive points,
to propose relevant technical alternatives,
to reduce implementation conflicts,
to improve coordination between different trades.
Design-assist is particularly suited to highly complex renovation projects, which are common in Geneva and the canton of Vaud.
General contractor and project management: an integrated and deliberate model
Combining general contracting and project management within the same structure allows for:
improved readability of the sequences
smoother team coordination
proactive problem-solving on-site,
a clearer and more serene customer experience.
This model is neither a break with Swiss standards, nor a challenge to existing roles.
It represents a logical evolution , adapted to the reality of current renovation projects.
An approach centered on technique, coordination and human experience
Beyond the technical aspects, this integrated model provides an essential benefit: the human stability of the project.
It allows:
architects to focus on design and maintain leadership in overall conception,
to enable the execution teams to work within a clear and anticipated framework,
to provide clients with a more understandable and reassuring experience.
The management of the works then becomes a true steering tool , serving the final quality and the experience lived during the project.
Conclusion: a coherent response to the reality of renovations in French-speaking Switzerland
In Geneva and the canton of Vaud, renovation projects require:
anticipation,
coordination,
decision-making clarity
constant support.
A model integrating general contracting, project management, early involvement, value management and design-assist makes it possible to meet these requirements in a coherent, reliable and sustainable way, while respecting everyone’s roles.
