Independent Testing and Technical Due Diligence Services in Ireland

Independent testing and technical due diligence (TDD) are essential tools for delivering high-quality construction and making informed property investment decisions. These third-party services help reduce risk, ensure compliance, and support smarter, data-driven decision-making throughout the property lifecycle — from design and build through to long-term asset management. 

Whether you’re acquiring, leasing, financing, or maintaining property assets in Ireland, a clear, objective understanding of a building’s condition and compliance status is key to protecting your investment. 

On complex or high-value construction projects, independent inspections provide objective oversight that goes beyond internal quality checks. When carried out by accredited professionals with no involvement in the design or build, these inspections offer added assurance of regulatory compliance and construction quality. 

Independent testing in Ireland plays a vital role in aligning developments with the Building Control Act 1990, Building Regulations, and relevant Technical Guidance Documents. By identifying non-compliance early, it helps ensure safer, more resilient buildings, and helps project teams avoid costly delays at handover. 

ORS supports clients nationwide with expert third-party reviews and inspections during construction, tailored to project complexity and risk profile. 

Technical Due Diligence (TDD) is a comprehensive service offered by ORS to support clients during property acquisition, leasing, financing, or asset handover.
