Norwich Castle Vibration Monitoring

Project Overview

Norwich Castle in Norfolk were holding a ‘Big Boom’ spectacular firework display which lit up the skies over the Castle in July 2016 for the Lord Mayor’s Celebration and all the fireworks used in the display were fired to the beat of music to make it a more exhilarating show with thousands of fireworks going off in the space of a few minutes to create a really high impact show with a big finale.


History

Norwich Castle was built by the Normans as a Royal Palace 900 years ago and the Museum houses fabulous collections of fine art, archaeology as well as the Royal Norfolk Regimental Museum collection, Costume and Textile collection and Natural History Collection, with approximately 3 million objects in the collections


Vibration Monitoring Services Ltd were approached as there were concerns that the large firework display may have a detrimental effect on the sandstone structure during the display and to carry out a survey to monitor the vibration levels over a period of a week, prior to, during and following the firework display to determine the vibration levels in locations around the Museum.


Scope of Works

This was to install equipment which measures and records both the maximum vibration levels and the vibration frequencies in x, y and z directions at key locations within the Museum and set the monitors to collect data continuously throughout the week covering the Firework Display, once the data had been collected it was then downloaded and analysed to assess the effects on the building.


The data showed the fireworks to have an impact on sections of the Castle; the vibration amplitude levels compared to the frequency of vibration put the overall vibration levels within the British Standard Guidelines.
