I am working on a retirement home project comprising a reasonably large two storey building for older people and after completing a C/AS2 fire safety report recommended to the client that it could be worthwhile having a sprinkler system designed. That way tenderers can price on a known item, and it surely would help the design process in identifying issues/conflicts. Hopefully in the longer term it would result in a cost saving. To me it just makes sense. Tossing this idea around with contractors I discovered a marked lack of enthusiasm for this approach. While a documented design would assist in providing a level playing field for tendering, it was considered that it would not help during the construction process as the design would be unlikely to represent the real situation. Redesigns were likely during the build.
What experiences have people had with this issue? It must have happened before. Would really appreciate experiences and knowledge - bearing in mind that this is a provincial situation, which may be different to the big city.
Thanks for your time.
