Introduction
The building, which is already in existence, was initially opened in 1978 as a leisure centre provided by the local
council to the people of the community.
The building was originally built in the 1977/78 and has undergone various extensions and refurbishments in a bid
to maintain the services to the community. One of the most recent areas of refurbishment which the centre has
undergone is that of the wet changing areas.
The proposal is to renovate the areas identified within the layout drawings including a variety of strip outs,
changes of use and refurbishments throughout the entire of the leisure centre. This will also involve a variety of
stripping out, reusing and replacing the existing building services to the areas which will be affected as part of the
refurbishment. The details of the mechanical and electrical installation are detailed in this series of documents.
The centre is currently serviced with electricity, gas & water; it is not envisaged that these need to be upgraded as
part of the scope of this project; however pressure checks of the incoming water main should be carried out to
confirm sufficient is available to cope with any additional load incurred by these works. The contractor must make
allowances within their tender for main cold water boosting if their design calculations find this to be required to
achieve sufficient water pressure throughout.
Allowances must be made for the inspection and making safe of all existing services within areas that are to be
affected to ensure that services comply with latest industry codes of practice even in instances where services
affected run out of the demise of the planned works. These include BS7671 2008 17th Edition Wiring Regulations
and ACOP Gas Safety Regulations 1998.
The tender should include for all costs in this respect. The contractor must visit site to establish the extent of the
strip-out. No claims for additional monies in this respect will be considered.
