We are a project that is moving into an existing building, which has previously been fully fitted out set as a set of offices. The building has an existing central core with toilets and kitchen spaces that are maintained by the landlord. We are leasing a set of offices on the third floor and are undertaking a renovation of this space in order to suit our requirements. The building is naturally ventilated and there is an existing hard ceiling in place complete with light fittings and fire systems which we intend on retaining as per the existing layouts. We are installing no domestic hot water systems as part of our works or renewable energy systems. In fact we are not planning on installing or making any changes to any MEP system, with the exception of some changes to data cabling. As such we are undertaking no works in the scope of our project that require commissioning as defined by EA prerequisite 1 - Fundamental Commissioning. We would therefore like confirmation that because we are not undertaking any works that are requiring commissioning in the scope of our project that we still meet this prerequisite. We could make changes to the lighting system in the space to enable us to undertake works that require commissioning thereby enabling us to meet the prerequisite. However this would require us to remove and throw away perfectly good existing light fittings and we do not believe that this is a sustainable solution, particularly when it would only be done to meet this prerequisite.
