Movement Monitoring

Accurately reporting movement of structures.

• On Going Reports / Graphs • Tilt Sensors • Basement Builds • Piling Works • Underpinning

Working alongside Party Wall Surveyors and Building Contractors across London & The South East, we provide easy to understand monitoring reports to record structural movement (or lack of) over time.

We put your mind at rest during your building works by undertaking detailed monitoring surveys and producing clear, easy to read reports that help demonstrate the movement, or the lack of, during a building project.

Our monitoring service is typically utilised during projects where underpinning, basement excavation, and party wall works are taking place. The monitoring reports help you satisfy key requirements and agreements with neighbouring property owners.

During major structural works, we recommend speaking to your project manager about monitoring intervals. Usually, during heavy works, the monitoring surveys are undertaken weekly and then moving to a monthly basis when the less intrusive works are taking place.

Monitoring Survey FAQ's

The first stage in the monitoring survey process is to discuss the specification with either the Party Wall Surveyor or Structural Engineer for the project. Once this has been arranged then the monitoring survey company can prepare for the setting up works.

When on site, the monitoring survey company will fix prisms, reflective targets, crack gauges, demec studs and other devices used to monitor the required areas. Typically the devices are fixed mechanically using wall plugs and screws or using high strength adhesive.

The monitoring surveyor will take the initial base readings of the device or location to be surveyed. This will be used to compare against for future survey readings, the differences in the readings will be reported to the client.

We have been involved in a range of different projects varying in size. Typically, our monitoring survey service is applied for projects such as:

  • Basement construction.
  • Underpinning.
  • Heavy demolition.
  • Earth movement projects.
  • Settlement and deformation.
  • Insurance claims.

We operate both nationally and internationally, we have been as far as Liberia in West Africa to undertake our survey service.

However, we typically operate in London & The South East. This includes Kent, Hertfordshire, Sussex, Surrey, Suffolk and Essex

I used THS for the first time to produce drawings for one of our projects. I was very pleased with Toms reaction time to produce the finished article, as there were quite a few amendments. They are very financially competitive and very helpful. I would definitely recommend them and will be using them for any projects in the near future.

I had a great experience with THS - they were flexible around my schedule and very transparent about costs, what was included, etc. They were also willing to liaise directly with our architect, which saved me quite a bit of time ...and our architect was very pleased with their output. Would certainly use them again.

Again a very efficient service with quick turn around. A 3D scan survey this time of a site of a partly cleared site, mid terrace, with surrounding walls all over the place. Link to the 3D back the next day for engineer and steel erector to use in their modelling. I have used THS-Concepts before and I will again, when I next need a detailed survey.

THS provided an excellent service creating a measured survey of a very complex building in central London. The process was smooth, communication was excellent throughout, and the results were impeccable. Tom, Jack, Chris, and Lesley were all quick to answer any query and accommodate any additional requirements. I wouldn't hesitate to recommend THS or to use them again myself.
