Welcome to Collaborative Reporting for Safer Structures UK (CROSS-UK). CROSS is a confidential reporting system which allows professionals working in the built environment to make reports on fire and structural safety issues. The reports are then published anonymously to share lessons learned, create positive change, and improve safety. Find out more about the safety information we provide below.

Go to the 'Safety Information' page to find fire safety reports or information on structural safety issues and concerns.

If you are looking for a specific topic or category, use the filters to find the most relevant information to you, we have reports on concrete, steel, masonry, timber and many more categories.

If you know of or have experienced a fire or structural safety concern or incident submit a report to CROSS using the secure reporting system so we can share the lessons learned. 

CROSS-UK Newsletter 67


CROSS-UK Newsletter 67 has been published which includes expert comment on fire and structural safety reports.

Control of temporary works excavation

Poor, high-water content excavated material, slipped into a 15-20m deep borrow pit. The material had slipped to the bottom of the pit partially burying excavation, crushing and screening equipment. If this slip had occurred during working hours, the impact could have been very serious.

Fire spread through balconies

This report highlights that the extensive use of combustible materials in the construction of balconies can result in fire spread over the external wall to an extent which is inadequate for building safety, even buildings less than 18m.

Connection fixity considerations for steel frame modelling

This report concerns the modelling of joints when using computer programs. In some cases, engineers are applying rotational releases to joints in models but subsequently designing the connections as rigid. This leaves a fundamental mismatch between analysis and design which may lead to unsafe structural connections argues a reporter.

Do planning applications hinder safety improvements?

A potential issue about the reconstruction of a structurally inadequate external fire escape from a building has been raised with CROSS.
