Project Type: Generator Upgrade | London

Project Brief: Remove and relocate existing generator radiators to create
space for the new equipment. Design, supply and install 2 No. 2.5 MVA
diesel generators in bespoke acoustic enclosures, together with all
associated control systems and auxiliary equipment.

Project Description: The client appointed E-TEC to carry out the generator
upgrade works at their prestigious London data centre. E-TEC was chosen
for our specialist experience in the provision and execution of particularly
difficult projects such as this. In short, an external location on the ninth floor
was chosen for the new equipment which was already occupied with two
large cooling radiators serving the existing sets. Since the proposed location
for the new equipment was away from the central core of the building, the
weight limitation of loading allowed per square metre was dramatically less
than the proposed load to be installed. The solution was a radical design
change which saw the cooling radiators sited remotely from the engine and
suspended on steelwork from the floor above. The engine exhaust silencers
were acoustically housed and suspended in the same way. To raise the
equipment to high level prior to locating and building the generators and
associated acoustic housings in situ, extensive steel work adaptations,
temporary removals and extended crane operations were required.

Design Criteria & Scope of Supply:

• Design, supply & install 2 No. 2.5 MVA diesel generators together with
all associated control systems & auxiliary equipment

• Bespoke acoustic enclosures designed to achieve a maximum noise level
of 65 dB(A) @ 1m

• Generators were unable to be installed in conventional form due to a major
weight restriction

• Project management, crane lifting, logistics & sequencing was required
to locate the new equipment to the ninth floor

• Integration of the new E-TEC control & monitoring system with existing
live equipment & controls
