Project summary
The West King Street Renew project is based in Hammersmith, West London. The final scheme brought 204 new homes, a four-screen cinema, shops, restaurants, cafes, office spaces and a new civic campus to the Hammersmith area.
The brief
Murphy Geospatial were instructed by Ardmore Group to carry out structural monitoring of the steel truss surrounding the West King Street Renewal development in London.
The challenges
In addition to the automated structural monitoring of the steel truss at the roof level, an additional requirement was introduced: the structural behaviour of steel columns located on multiple floors needed to be monitored throughout the construction phase. Each floor had four columns, each in a separate, confined room at a corner of the building, creating significant accessibility challenges.
Due to limited access to windows, Murphy Geospatial had to work within tightly constrained timeframes and coordinate closely with the site team to ensure all tasks were completed within each designated shift. Furthermore, because the columns were not monitored continuously, a reliable control point network had to be re-established at the beginning of each monitoring session to maintain data accuracy and consistency.
Our work
Two Automated Total Stations (ATS) were installed on the project, delivering continuous data to an online monitoring portal. Positioned on the West and East Elevations, respectively, the ATS units continuously measured over 90 geodetic reflector prisms magnetically attached to the steel truss.
A total of 32 monitoring targets were installed on steel columns across various levels of the building to assess their structural behaviour during construction. In addition, over 100 control targets, both temporary and permanent, were used for traversing purposes. To support accurate referencing, four new ground control points were established outside the zone of influence.

Monitoring Technology Used
-
2 Automated Total Stations (ATS)
-
90+ reflector prisms for truss monitoring
-
32 column monitoring targets across multiple floors
-
100+ temporary and permanent control targets
-
4 newly established ground control points
-
Online portal providing real-time data visualisation and trigger alerts
Our team
Our monitoring team consisted of a project engineer to prepare and supervise the installation, a monitoring engineer to install the system and set up the network, and a survey team to carry out the installation and survey of the control network. A designated project manager was assigned to ensure the automated monitoring system ran smoothly and the client was kept informed of the monitoring results.
Results
All systems were installed and running within the allocated shifts required to get everything set up. The system remains in place for the duration of Ardmore Group’s work.
The observation data was viewed via an online portal and summarised in a daily/weekly report. If a trigger was breached or a critical event occurred, the client was ready to take the necessary action before it was too late.
The success of this project underscores our reputation for delivering services that equip our clients with the data-driven insights they need to make decisions at every stage. We draw on the experience and skills of our people to deliver certainty our clients can trust.
