Our project teams are hand-picked and from the top construction professionals in London. This enables us to offer the very best service to our clients, in the very top tier of the market.

Movement Monitoring

Another field of expertise that we have made our own is movement monitoring. We have assembled our own expert in-house team of engineers and have provided them with the very latest monitoring equipment.

They can offer a completely bespoke package to the project engineer’s requirements. Providing this service as an in-house package allows us to better monitor potential movement and to respond more quickly should action be required.
