Excel Building Surveying Ltd have recently been commissioned to complete floor level surveys of a number of varied properties to confirm compliance with Concrete Society Technical Report 34 (CSTR34) table 3.1. Testing was completed to measure properties E & F with regard to floor classes FM3 and FM4. A 3m grid was measured using a 1m surveyors wheel and marked in chalk on the various floors. Areas covered by materials, plant, work stations etc are ignored. A rotating lazer level is set up on a tripod and levels taken at the 3m grid points (nodes). A property II "F" meter is then pulled along a suitable number of node lines to determine the change in elevational difference over 300mm measured continuously. Results are analysed to determine 95% of measurements and this figure is then used to confirm compliance or otherwise. The pass criterion may be critical particularly if the floors are to be used for high racking and fork lifts and if the buildings are part of safety critical infrastructure as recently completed by Excel Building Surveying. In addition, we have tested a number of the same floors for slip resistance using BRE Pendulum slip resistance test equipment and resistivity using Proceq Resipod 4-pin Wenner probe.
