Our monitoring surveyors record and measure the movement or deformation of a building or structure across a broad range of projects. From new build developments through to historic and heritage landmarks, a monitoring scheme can help identify any potential issues within a structure and allow a plan of remediation to be established before further problems develop.
We work to a high level of accuracy with project specifications being established for movement as precise as sub mm. We can also supply our clients with real-time project data, ensuring that any problems can be identified and communicated via SMS or email immediately so that appropriate action can be undertaken on site.
Our monitoring programmes generally fall into two distinct categories. Manual monitoring schemes can be set up quickly, with our team available to attend site on a regular basis to consistently measure the monitoring targets. The frequency of attendance is normally specified by the client at the start of the project but can change in line with with changing site activity. You will be provided with an ongoing set of data, generally in spreadsheet format, although other data and outputs such as 3D digital models are also available. Previous survey data can also be provided to check for any noticeable trends or patterns in movement.
The second option is a fully automated monitoring scheme where we will attend site and establish monitoring technology that can continuously measure fixed points 24/7. Data sets can be provided for timeframes that suit you best (i.e. for your Monday morning team meeting) but should any movement be detected in the meantime, we can use alert systems to communicate with you by text message or email should pre-determined tolerance levels be breached.
We have many years of experience in this area and have worked on a range of schemes and programmes, including:
- The refurbishment of a building development in the heart of London. This automated scheme continuously measured small degrees of movement in 3D within the structure over several months.
- The structural monitoring of a new build apartment block in Chester. This was a 12-month project monitoring 16 glass prisms continuously, combined with continuous data stream from 8 eight tilt sensors 24/7.
- A new build waterside development which had encountered failure of the waterproofing as well as the problem of movement in the supporting columns or concrete floors. Daily monitoring of the floors and columns took place for several weeks.
- The external façade of Norwich Castle to monitor the stability of the overall structure whilst internal alterations were made. Precise measurement took place monthly and data was then compared to previous observations to check for any changes.
As part of our monitoring division, we can support your project with a range of environmental monitoring services either as an addition to your structural monitoring programmes or as a bespoke package of work.
Asset condition surveys are an ideal solution for assessing the impact of major infrastructure and construction projects on the wider built environment. They can help establish whether there has been any consequential damage to neighbouring buildings or structures during the work by carrying out pre- and post-construction surveys.
