Preparing for controlled execution

The majority of difficulties encountered during a renovation arise well before the construction site: unclear scope, unrealistic budget, unanticipated technical constraints or ill-defined responsibilities.

A pre-construction phase provides a clear framework, informs decisions and reduces uncertainty before work begins.

Structure the project before execution

Pre-construction is a phase of progressive structuring designed to transform an intention — whether it is carried out by a client or by an architect — into a feasible, coherent project aligned with the planned investment. Each step provides more clarity and prepares the necessary decisions for controlled execution.

Regardless of how the project begins, pre-construction and, if necessary, design assistance, allow the construction phase to be started with a clear vision, assumed decisions and continuity between design and execution.

Pre-construction with architectural plans

In the presence of architectural plans or an established design direction, pre-construction is adapted to capitalize on the work already done and focus the analysis on feasibility, field constraints and preparation for execution.

Pre-construction
On-site feasibility study

On-site analysis of existing conditions, understanding of technical and regulatory constraints, reading of volumes and networks, identification of potential risks, initial feasibility hypotheses, clarification of the project's structuring issues. This phase allows us to lay a realistic basis before any binding decision. Implicit objective: to avoid unrealistic assumptions and to secure the first orientations.

Pre-construction
Phases 2 & 3
Project Framing, Budget and Intentions

Approfondissement des intentions de conception et design, définition du périmètre d'action précis, analyse des options techniques possibles, alignement du budget avec les objectifs du projet, premières orientations de phasage et de délais.
Ces phase permet d’arbitrer avec discernement et d’orienter le projet vers une direction claire et assumée.

Objectif Implicite : transformer des intentions en décisions éclairées et cohérentes

DESIGN ASSIST — project development without design plans

Design assist is aimed at customers who want to develop their project without established architectural plans.

Based on ideas, references or intentions, we support the structuring of the project by aligning the design choices with the technical feasibility, the constraints of the site and the budget.

Depending on the needs, sketches, volumetric studies or 3D renderings can be integrated as decision-making tools.

Process

Our process delivers clarity and calm at every stage.

With structured pre-construction phases, attentive leadership, and continuous oversight, thoughtful ideas become polished results - delivered seamlessly and without surprises.

Phase 1 Consultation & Feasibility

Analysis of the project, scope and constraints in order to verify technical feasibility and alignment with a realistic overall budget.
