Facade Surveys

EWS1 FRAEW & PAS 9980 Surveys and Opening-Up Specialists

Intrusive surveys, inspection support, fire engineer coordination, and full reinstatement.

Trident Facades Surveys delivers PAS 9980-aligned opening-up and reinstatement works to support compliant FRAEW and EWS1 assessments.

We work directly with building owners and managing agents, and in partnership with fire engineers, surveyors, and consultants, providing safe, precise access to external wall systems so inspections can be carried out accurately, efficiently, and with confidence.

EWS1 FRAEW INTRUSIVE SURVEYS

We deliver specialist façade compliance and investigation services across three core areas: EWS1 Survey and Certification, FRAEW (Fire Risk Appraisal of External Walls), and PAS 9980 Opening Up Services.

Acting as the delivery partner for engineers, consultants, and building owners, we manage access, coordination, and intrusive works to ensure every stage is carried out safely, efficiently, and in line with current fire safety guidance. Our structured approach keeps projects moving, reduces delays, and provides a clear, auditable route from inspection through to final sign-off.

EWS1 Survey and Certification

We provide a fully managed route to EWS1 Certification — coordinating access arrangements, permits, PAS 9980-aligned intrusive surveys, structured inspection support, and accredited fire engineer sign-off.

A single, organised process that removes friction, reduces delays, and keeps projects moving while maintaining full compliance and auditability.
