Used by Party Wall Surveyors & Contractors across London & The South East. THS Concepts provides easy to understand movement data for structures that are undertaking or near to construction works such as basements, extensions, underpinning etc.
Precise and easy-to-understand monitoring reports to show structural movement over time.
We provide monitoring surveys to clients in the process of undertaking extensive structural works to their property. Our monitoring service is typically utilised during projects where underpinning, basement excavation, and party wall works are taking place. Our monitoring surveys and subsequent reports help clients satisfy key requirements and agreements with neighbouring property owners.
Your monitoring survey works can be undertaken at intervals to suit your agreement terms. Typically we undertake weekly readings however some jobs specify daily, and others monthly for instance. When setting up your project we use fixed reflective targets or prisms to accurately record data over a set time period. The reports you will receive are clear to read and easy to understand with vertical and horizontal degrees of movement shown.
Professional Reports & Data
Your reports will show horizontal and vertical movements over time in a clear, easy to read manner. We typically return all monitoring survey reports within 1 day of the survey. If we notice any major movements whilst on site then these will be flagged to the relevent site team member.

We understand the need to get your project turned around quickly. Usually, we can get to you within 7 days and have the drawings turned around in another 7 working days based on a drawing package consisting of plans, elevations and sections.
If you are really pushed for time then please let us know and we shall see what we can do for you!
Typically we fix 25 x 25 mm reflective tape targets to walls using epoxy glue. The reason being is that the targets have to be very secure to allow the subsequent surveys to be undertaken as accurately as possible. We ttry and place all targets away from locations where they can be peeled off and in areas where paintwork damage can be reduced.
If we need to fix prisms then this usually requires a little more work as we may need to drill into existing walls to fix and resin them in.
At THS Concepts we provide our Surveyors with a method statement on how the work should be undertaken combined with a risk assessment outlining potential dangers on site and how these can be mitigated. If you need these supplied for your project then please let us know so as we can send before we arrive.
We can supply you with a monitoring survey proposal which outlines elements such as where targets can be positioned etc. We do advise that you speak to a Building Surveyor who can verify or set out the monitoring survey requirements.
No problem at all. If you follow the link below you will see an example PDF report from a previous job we have undertaken. We have also attached an example graph showing the movement on one point. For privacy reasons, we have had to take the job name details off of the report.
