Movement Monitoring Surveys
Monitoring buildings & structures across London & The UK
• High accuracy – Surveys undertaken using Leica total stations.
• Small / Large Sites – Basements, piling, underpinning, tunneling.
• Detailed Reports – Easy to understand monitoring reports & graphs.
• Experienced – Over 2000 surveying jobs since 2013.
• Fully insured – £500,000 professional indemnity.
Working across London and the UK, we setup, undertake and report on structural movement for projects such as basement construction, underpinning, piling, insurance claims, tunnels and more.
Movement Monitoring Features
We put your mind at rest during your building works by undertaking detailed structural movement monitoring surveys and producing clear, easy to read reports that help demonstrate the movement, or the lack of, during a building project.
Our structural monitoring service is typically utilised during projects where underpinning, basement excavation, and party wall works are taking place. The produced reports help you satisfy key requirements and agreements with neighbouring property owners.
THS Concepts have been undertaking movement monitoring surveys for over 8 years in and around London. We have worked on a range of different projects from £25 million pound refurbishments to small basement builds. You can rely on our monitoring survey team to quickly get to your site, set up the the scheme and reliably report on the movement in your structures.
Frequently Asked Questions
A fixed position monitoring survey is the method of monitoring a set location on a wall / structure and observing movement in the horizontal and vertical planes over time.
Fixed position monitoring is used for a number of projects ranging from small basement projects to large infrastructure projects such Crossrail tunnel project under London.
The monitoring project always starts with the initial setup of the monitoring targets and local survey control network. The targets are fixed to the structure in the pre-designated locations utilising either glue or drilled screws.
Without a fixed monitoring point to resurvey each time, the consistency will be poor or non-existent. Fixed points are installed on to the structure and usually consist of survey prisms or reflective target stickers. When using prisms, they are typically secured using screws drilled into walls or using high strength glue.
A local survey control network also needs to be installed. This involves placing survey targets (prisms or reflective survey points) away from the site. These are used by the total station as a way of calculating its precise position each time a monitoring survey needs to be undertaken.
A monitoring survey is undertaken using a piece of equipment called a total station. A total station is a high accuracy optical instrument that is used to measure distances and angles. Total stations are usually mounted on tripod legs, whereby the operator can look through the lens and record survey points. In some cases, automation is required If so a total station can be left in a safe location and operated remotely.
At each survey interval, the total station has to be set up using the local control network. Once set up accurately, the monitoring survey process can be undertaken. Each monitoring point is precisely surveyed using the total station and recorded to the instrument.
Once this data has been reached the office, it is uploaded to the monitoring survey software, which can generate data to illustrate movement (or lack of) over time.
We help our clients monitor cracks that are potentially opening or closing. We install demec studs or gauges to accurately record movement over time.
We install tilt sensors on walls that need to be monitored for angular movement. Our tilt sensors work remotely and can report readings as often as every minute!
