A Newsletter from CROSS-UK containing reports on structural safety issues.
Note: this Newsletter was published by CROSS (Confidential Reporting on Structural Safety). Since March 2021, Confidential Reporting on Structural Safety is renamed Collaborative Reporting for Safer Structures (CROSS).
Structural steel - reinforced concrete interface
A reporter describes how the substructure of a building was constructed out of position to the extent that the steel frame could not be erected to tolerance and could not be connected to the holding down bolts.
Steel portal frame erection
A reporter describes how a steel portal frame collapsed during its erection.
Timber design concerns
A reporter says what he has seen of the quality of the structural engineering design of roofs in many hundreds of projects is lamentably low.
Mobile phone masts
The concern of an overseas reporter is that erection, foundation design and construction, and maintenance of mobile phone masts are not carried out adequately.
Small bridge inspection
A student discovered corrosion on a small bridge while carrying out a survey for their final project/dissertation.
Steelwork connection design
A reporter was asked to design connections for a multi-storey building for which the frame had been designed by another engineer. The result was a near collapse situation.
Precast concrete demolition
During the demolition of a tower block, a column collapsed unexpectedly.
Differing reinforcement couplers
On a recent project, because of supply problems, the contractor decided to change from the specified rebar couplers (type ‘A’) to those of another manufacturer (type ‘B’).
The failure was of a two-storey high trussed girder with a 36m span, designed to carry a composite steel and concrete floor at the lower level and a trussed roof at higher level.
Local authority checking
A reporter feels that many small consulting engineering companies rely on local authority building control departments to check their work in lieu of proper in-house quality control.
