Key Services
You’re delivering large, multi-site, or live-facility projects (hospitals, campuses, utilities, ports) where operations can’t stop.
The project carries public, regulatory, or ministerial scrutiny, where decisions must be defensible.
You’re managing historical uncertainty, residual asbestos, incomplete records, or legacy removals.
The programme is time-critical, with significant commercial or reputational risk if delays occur.
You need an independent second opinion on methodology, clearance strategy, or lab results.
