Owner’s representation (assistance à maîtrise d’ouvrage, AMO) means representing the owner in dealings with the architect, engineers and contractors during all phases of a construction or conversion project, or when a dispute or a problem (contractor insolvency, defects) arises. As an owner’s representative based in La Tour-de-Peilz, Immersia supports private owners, condominium associations, investors and institutions on the Swiss Riviera, in the canton of Vaud and in Valais.
An owner without a technical team signs contracts it did not draft and receives invoices it cannot check. The owner’s representative restores the balance: defining your needs, controlling costs, timescales and quality, and preparing each decision.
Who owner’s representation is for
- Investors and institutions without an in-house technical department.
- Institutions, municipalities and companies carrying out a one-off project: clinic, hotel, professional premises.
- Private owners building, converting or raising a villa or a building.
- Condominium associations (PPE) renovating the building envelope, heating, façades or lift and looking for a neutral third party.
Our owner’s representation services
- Brief and specifications: floor areas, unit types, standard of finish, energy performance.
- Consultants: consultation of architects and engineers, negotiation of fees, contracts, insurance.
- Costs: overall estimate by CFC code (Swiss building cost classification), monthly monitoring of commitments, control of invoices and variations before payment.
- Timescales: master schedule, critical path, permit and contract award milestones.
- Quality and compliance: review of plans, SIA standards, follow-up of the permit and of objections.
- Risks, decisions and handover: risk register, mediation between consultants, lists of defects, final account, SIA 118 guarantees.
Owner’s representation, project management or construction management?
The owner’s representative controls a defined project on behalf of the owner. Property project management comes in earlier and includes strategy, financing and marketing. Construction management runs the site. Immersia offers all three, separately or together.

Why choose Immersia as your owner’s representative
- Eric Bilard, former sales director at Losinger and Steiner, qualified in construction management, knows the contracts, variations and defects of general contractors from the inside.
- Maxime Willemin, certified construction manager, and Céline Martin, REG B architect, design the projects, draw the plans, write the tender documents and check the invoices as practitioners.
- Immersia does not carry out works and has no commercial ties to any firm or contractor.
Frequently asked questions about owner’s representation
Do I need an owner’s representative if I already have an architect?
The architect designs and directs the project. The architect does not control their own fees or timescales, or the financial consequences of their choices for you. The owner’s representative brings this independent view.
How much does owner’s representation cost?
Fees reflect the actual volume of work and the phases entrusted to us. The first meeting and the analysis of your file are free of charge, then you receive a written proposal. Our remuneration consists of a fixed fee and a percentage of the savings we achieve for you.
Do you work for condominium associations?
Yes. We explain the issues to the co-owners, prepare the general meeting, produce updated plans after conversions, coordinate the contractors and follow up cantonal subsidies.
