Network Rail CAT III Checks
CAT III checks provide independent verification that scaffold designs meet Network Rail’s engineering and safety requirements before works proceed. We review drawings, calculations, and assumptions to confirm compliance, buildability, and risk control in a rail environment.
Keep your project on the right track with an independent CAT III check.
DH Scaffold Services Ltd delivers robust Network Rail Category 3 design reviews to verify compliance, technical integrity, and safety-critical assumptions before work proceeds.
We provide an independent, engineering-led review of scaffold design packages for Network Rail projects—confirming compliance, design basis, and buildability so approvals stay on track.
As rail works are subject to a formal technical approval process, an independent Category 3 check may be required to verify that the design is robust, compliant, and fit for purpose in a safety-critical environment. We review the full design package, including GA drawings, calculations, tie strategies, loading assumptions, and any project constraints, then issue clear comments and a structured check certificate/report to support submission.
Our approach is thorough and unbiased: we challenge assumptions, identify risks early, and help prevent late-stage design queries, delays, or costly revisions. The result is a CAT III check you can stand behind—giving confidence to duty holders and ensuring the scaffold delivers a safe, buildable solution on site.
