Study prioritization CC2/CC3 buildings completed

Study prioritization CC2/CC3 buildings completed

The work of the National Coordinator Groningen (NCG) starts by determining which buildings reinforcement is needed in connection with the risk of failure to a (possible future) earthquake. This concerns residential buildings, but the NCG also has special programs for schools, hospitals, heritage sites and farm houses. Buildings with a CC2/CC3 consequence class, such as shops, communal buildings and sports halls, are often not included in the NCG working stock.

In order to determine as efficiently as possible or, and if so which objects to be added to the working stock, the NCG has asked TTE Consultants and Cohere Consultants to develop a prioritization system for these objects. The precondition for this was that only publicly available data was used. The preparation of the prioritization method is a first step. On the basis of the prioritization, the NCG can determine which objects need to be further examined for structural vulnerability and possibly to be added to their current working stock.

Wheel out-of-roundness

Wheel out-of-roundness

In collaboration with Ricardo Rail, Cohere Consultants is studying the influence of wheel out-of-roundness on environmental vibration levels. The study is commissioned by ProRail and includes data-analysis of measured accelerations at axle level in combination with measured vibration levels at free field.

The goal is to increase understanding on how to reduce environmental vibration impact of railway lines in the Netherlands.

New website www.i4damsafety.com

New website www.i4damsafety.com

The i4damsafety consortium has a new website: www.i4damsafety.com. Cohere Consultants is part of the international consortium of parties with high end expertise in the fields of monitoring, ground investigations, soil mechanics and geotechnical/geological risk assessments.

I4damsafety tries to increase dam safety (with a focus on tailing dams) by advocating an integral approach of both monitoring and testing as well as modelling and prediction. This integral approach is necessary to understand the current state of a dam and to be able to take necessary mitigating measures when needed.
