Intrusive Investigation FAQS

What is an intrusive investigation?

An intrusive investigation is a detailed assessment that goes beyond visual inspection. It involves carefully opening up parts of a building to access concealed areas such as voids, structural elements, fire compartmentation zones, and external wall systems to confirm actual construction conditions.

When is an intrusive investigation required?

Intrusive investigations are typically required when standard surveys cannot confirm hidden risks or construction details. This includes uncertainty around fire stopping, structural integrity, external wall build-ups, or where further verification is needed to support compliance, refurbishment, or safety decision-making.

What does the investigation involve?

It may include controlled opening-up of walls, floors, ceilings, service risers, or external wall systems to access concealed construction, along with inspection and verification of fire protection, structure, and materials.

Who carries out the work?

Investigations are carried out by appropriately qualified professionals, typically including Chartered Structural Engineers (Institution of Structural Engineers), Chartered Civil Engineers (Institution of Civil Engineers), RICS Chartered Surveyors (Royal Institution of Chartered Surveyors), and qualified fire engineers, typically holding Chartered Engineer (CEng) status via the Engineering Council and membership of the Institution of Fire Engineers (IFE), operating to recognised UK professional standards.

Will the building be damaged?

Works are limited, controlled, and targeted to specific areas required for inspection. Openings are kept proportionate to the scope of investigation and can often be reinstated following completion where required.

Is the price fixed?

Yes. All quotations are fixed-scope, with agreed parameters, assumptions, and deliverables defined before instruction. Costs only change if the scope of work is later amended.

What will I receive after the investigation?

You will receive a structured report including photographic evidence, findings from opening-up works, identified risks or defects, and clear recommendations for next steps.

Are engineers qualified and insured?

Yes. All professionals hold relevant qualifications, experience, and Professional Indemnity Insurance. Full credentials are provided as part of a due diligence pack before instruction.
