A major part of our workload over recent years has been to provide structural data for Engineers where a building is being refurbished, or some change of use is planned.   Often, no drawings exist for the structure, and we are asked to provide data regarding type, depth and size of foundations, reinforcement type, size and configuration, concrete grade, details of structural steelwork and connections, including locations and numbers of bolts, their sizes, spacings and so forth.

We have considerable experience in this area, including the need to work very cleanly, with minimum disturbance to the occupants.  This often necessitates out of hours working and negotiation with owners or occupiers of neighbouring buildings.

We aim to provide the information needed by the Engineer in the clearest most concise way possible.  A typical drawing from one of our reports is given below.
