Your project manager doesn’t seem to be on your side
You hired a project manager (maître d’œuvre) to coordinate your building works because you wanted peace of mind: a professional defending your interests in front of the contractors. Except on site, something feels off. Every time you flag a defect, they play it down, they almost always take the contractor’s side, and you have the uncomfortable feeling that the two of them know each other well — maybe they’ve worked together for years on other projects. You hesitate to say anything, because you have no proof, just a growing gut feeling that builds up meeting after meeting.
It’s an uncomfortable position, because you’re paying this project manager precisely to have an independent, protective set of eyes on your behalf — and instead you find yourself doubting the one person who’s supposed to represent you technically on site.
Why this happens
It isn’t always deliberate dishonesty. Many project managers work repeatedly with the same contractors, project after project, which naturally creates habits and trust relationships. Without any bad intent at the start, these can end up favouring the contractor over the client — especially if the project manager knows they’ll need that same contractor on future jobs.
There are also cases where the project manager themselves supervised a stage of the works poorly, and acknowledging a defect would mean admitting their own failure to oversee it properly. In that case, they have a direct incentive to downplay the problem rather than document it objectively. Either way, the client ends up alone, facing a situation where the person meant to protect them has — consciously or not — a conflict of interest.
What you can do now
Faced with this kind of doubt, it’s important to act without unnecessarily breaking the relationship with your project manager, while still protecting your position:
- Systematically request written site reports rather than relying only on verbal exchanges.
- Keep a record of every defect you’ve flagged and the response (or lack of response) you received.
- Never sign a document (handover certificate, minutes) under pressure — take the time to check it yourself.
- Compare the project manager’s recommendations against the applicable technical standards (DTU), whenever possible.
- Bring in a second technical opinion, completely independent of the project manager–contractor pairing, on the points you find questionable.
This second opinion isn’t about systematically challenging the project manager: it’s a targeted check that tells you whether your suspicion is justified or not, without depending solely on the word of the person you doubt.
How an independent expert helps
Frédéric steps in precisely as that fully neutral third party. With 15 years of experience in public works and project management, he understands exactly what a project manager’s role and responsibilities are, which allows him to assess whether the site was properly supervised or whether there was a genuine lapse in oversight.
His involvement has no connection whatsoever to your project manager or to the contractor in question. On site, he uses Trotec measuring instruments (crack monitor, thermal camera, moisture meter) to objectify every disputed point with hard data, rather than conflicting opinions between two people who know each other. The report he delivers precisely documents the defects observed, independent of whatever has been said — or downplayed — on site up to that point.
Cassini Expertise carries out no construction work, sells no materials, and has no ties to any project manager or contractor in the region: this complete independence is exactly what’s missing in a relationship where the project manager seems too close to the contractor. This report puts you back on equal footing in the discussion, backed by technical arguments no one can simply wave away.
Frequently asked questions
How can I tell if my project manager really isn’t neutral?
Systematic downplaying of issues, reluctance to put exchanges in writing, or evasive answers to your technical questions are all signs worth taking seriously.
Can I bring in an expert without telling my project manager?
Yes, that’s your right as the client. You don’t have to justify this step to them.
Can an independent expert replace a project manager?
No, their roles are different: the project manager coordinates the site, while the expert steps in on a one-off basis to objectify a specific point of disagreement or doubt.
What if the expert’s report contradicts my project manager?
That report becomes a solid technical argument to reopen the discussion with them — or even to pursue their liability if a supervisory failure is confirmed.
