OF BUILDING SERVICES
2.1
General
2.1.1
Access & Maintenance
The access & maintenance requirements of the engineering services have been considered during
the outline scheme stage. This includes the legal requirements of modern design and construction,
good practice design methods and plant replacement strategies.
Risk assessments for any residual hazards will be completed as part of the final scheme design.
Major plant replacement access for the plant has been established in principle. Lifting equipment,
provided by a specialist lifting company, would be required for the removal of any large pieces of
equipment, due to the access available.
A preliminary Safety in Design Worksheet and Plant Replacement Schedule have been issued under
separate cover from this report.
2.1.2
Lifts
Full calculations will be completed in a later design stage to show the selected lifts perform within the
criteria set out within CIBSE Guide D for the relevant residential development.
However, being a residential scheme the waiting times and handling capacity measures are not
usually the key selection criteria but the physical size and shape of the lift cars to accommodate
large items of furniture, white goods, beds, cycles etc. Therefore within each core the favoured car is
usually a 13 person car option.
Generally, there is no adverse performance restriction in having a smaller lift size with a 630kg lift
performing within the CIBSE recommendations and also meeting any firefighting restrictions for
current or future fire fight lift requirements. The decision should purely be based on the preference of
whether a larger lift for ease of moving furniture is required.
2.2
Statutory Supplies and Services Provision
2.2.1
Electrical Supplies
Liaison with UK Power Networks is ongoing regarding the new incoming supplies to the development
and any necessary diversion works required to create availability is ongoing.
