Building expertise for local authorities
An independent technical look to secure your decisions
Do you manage the built heritage of a commune, an intercommunality, a department? Schools, gymnasiums, town halls, multipurpose rooms, social housing: these public buildings represent important investments, subject to strict budgetary constraints and transparency obligations.
Calling on an independent expert means securing your acquisitions, arbitrating technically before work, managing claims calmly, and protecting you from disputes with companies.
The problem? Communities may be reluctant to seek expertise because of fear of costs or lack of awareness of possible remedies. Error. A euro invested in expertise can avoid tens of thousands of euros of malfeasance or litigation.
