Fulham Gasholder Monitoring, London

Get in touch

Project summary:

National Grid appointed Erith Contractors to demolish and remove the gas tanks at Fulham Gasholder site to make the area suitable for future development to provide valuable housing and employment space.


The brief:

Erith Contractors  instructed Murphy Geospatial to undertake the monitoring works during the demolition of the tank’s physical structures and foundations as well as three prefabricated buildings existing within the site.


The challenges:

Murphy Geospatial installed an ATS system, including all the communications hardware and power control on the roof of a nearby building, along with 16no. monitoring glass prisms attached to 1.5m posts that were installed by Erith around the gasholders.

This setup for monitoring glass prisms was a solution required due to soft ground. 1.5m long posts were embedded into the ground and monitoring glass prisms were attached to the top of each post.


Our work:

Murphy Geospatial approached the works proposing the installation of an Automated Total Station system because of the increased frequency of readings required.

This system allows for defining the number of readings per day without additional costs, and also enables the monitoring works to be carried out without requiring operatives in the middle of demolition operations, increasing the levels of Health & Safety.

An elevated location was chosen to increase the field of sight of the instrument, which additionally reduced the number of instruments required.


Our team:

Our experienced team of monitoring technicians and project managers, led by our Head of Monitoring, Andrew Masters, ensured that the system was installed correctly the first time and that the data flow between the site system and the online web portal was set up appropriately.

The online database was customed with graphs to show the results relevant to our client, including an automated alarming system.

The team also prepared and issued periodic reports for the client’s records.


Results:

The proposed solution provided geospatial certainty to our client throughout the duration of the project.

The readings were obtained at the desired intervals and the data was analysed daily to ensure any outlier data was spotted in time allowing the reasons causing it to be identified and resolved timely; ensuring the purpose of the monitoring system remained in course.
