Are there unusual Health & Safety issues?
The outstanding results from initial trials from 1996 indicated that the movement gauges could not only provide early and quantitive data on foundation movements, but the reading of movement gauges were considerably safer than crack width gauges. Cracks tend to open at high level, so monitoring often involved working from ladders with the associated risks and costs. Once set up, movement gauges could be read by a single surveyor in most circumstances saving manpower costs. The use of laser levels even allow the movement gauges to be set up by one person if necessary. The use of glue and working on a building site are the obvious risks to be assessed.
