Walbrook House, Enfield - Stripping of Existing HPL Cladding

Client: London Borough of Enfield

Capital were appointed by Enfield Council to manage the Phase
1, stripping of the existing HPL cladding panels to Walbrook
House and for providing an Option Appraisal Report in respect
of the proposed design solution for reinstatement.

Capital acted as Design Coordinators, Structural Engineers, CA
and Principal Designers for the Phase 1 project and were
responsible for managing the initial opening up and
investigation works, agreeing the method of stripping and
temporarily waterproofing of the block and for management of
the works on site.

In addition to the above we also carried out an Option Appraisal

Report (for the Phase 2 reinstatement options) which set out the
proposed design solution and costs for reinstatement.
Procurement of the Phase 2 reinstatement works is currently
being consider as part of a large scheme to the block for a new
ground source heat pump heating installation and internal fire
upgrade works.

The scheme came about following the Ministry of Housing,
Communities & Local Governments advice to owners of
residential buildings with respect to building safety. Enfield
Council subsequently commissioned investigation works to all
their blocks, including Walbrook House, to determine the fire
performance of the cladding materials. This was in addition to
other fire safety improvement works that were proposed to
internal communal areas and common parts.

The results of the investigations established that the existing
cladding panels to Walbrook House didn’t meet the current
standards in respect of fire safety and other deficiencies were
found. As such removal of the existing cladding panels was
instructed by Enfield Council.

A specialist cladding contractor was appointed, and the method
and extent of access and stripping was agreed through a series
of design team meetings with the contractor and the design
team. The block was made safe and fully stripped within 12
weeks. The Phase 2 reinstatement works are due to go on site
this year.
