We were impressed with the Barrier Master on the M1 Jn16-19 project where we were dealing with large quantities of VRS posts in the central reserve. After the initial operator learning curve the outputs we achieved were very good. The machine was powerful enough to deal with most VRS posts including corroded sockets and long driven posts in well compacted ground. Two of the benefits from a safety perspective are 1) much less noise than a percussive extractor, and 2) there is no tension or stored energy and so not potential for uncontrolled release of it.
We are citing our experience on the M1 J16-19 with the Barrier Master when quoting for future work
