Forensic Investigations

DTU Civil Engineering and Prof. Jeppe Jönsson have been involved in a number of forensic engineering assesment works. DTU - Steel Structures group is ready to perform such works at short notice. In case of structural collapse of bridges or buildings it is our goal to be as fast as possible on site to make observations, since we know that the initial observations by academic experts are very important.

Assessment of Bridge Scaffolding Collapse over Highway - 2014  (Egebækvej broen - Helsingørmotorvejen)

See the report:
BRO 14-0-047.10: Overføring af Egebækvej over Helsingørmotorvejen. Redegørelse for svigt af stillads den 27.09.2014

   
Egebækvej bridge scaffolding failure.
Failure was in the wooden scaffolding part of the structure, which could not preserve horisontal equilibrium during pooring of the concrete, but see the report.

Evaluation of Banedanmarks works concerning re-establishment of the railroad bridge across Limfjorden - 2013

Report in Danish: Evaluering af Banedanmarks arbejde vedrørende genetablering af jernbanebroen over Limfjorden
The assessment was performed by emcon assisted by Prof. Jeppe Jönsson

Observations on the Collapse of the Scaffolding System for the Motorway Bridge at Exit 22, Nørresundby C - 2006

Observations report
DTU Civil Engineering was not involved in the assessment, but we made a short 2 page report of our observations and took many photos. It turned out that the final assessemt report by COWI came to the same conclusions as what was evident from our observation report.

 

Collapse of the scaffolding system due to poor stability of the steel support structure.
