Approves the implementation of Contract
Standing Order (CSO)18.03.3, 18.02.03 and 2.05.1(n) in order to
extend Etude’s appointment value of £92,820 (exc VAT)
by the value of £10,610 (exc VAT) totalling a revised fee of
£103,430 (exc VAT).

Reasons for the decision

Etude have provided Energy and Sustainability
services on the project to RIBA Stage 3 on the Mallard Place
project and are currently appointed through to the end of RIBA
Stage 3 and planning submission. Extending Etude’s contract
to cover work to a RIBA Stage 3+ will assist the project with the
unforeseen concerns around the Building Safety Act Gateway 2 (GW2)
submission and the current delays nationally with these GW2
applications getting approved. A Stage 3+ appointment for Etude
will assist in achieving more robust U-Value advice and in
providing thermal bridging calculations that will assist in further
developing the design with the current designer, which will assist
in de-risking the design ahead of submission for GW2
The benefit to the Mallard Place of the Stage 3+ appointment is
also to assist in de-risking the design for the potential
contractors, which could potentially yield much lower design
associated costs in the tenders as well as improving the chances of
receiving viable tenders for the works contract.

Alternative options considered

The Council may choose not to appoint Etude
for Energy and Sustainability services to RIBA Stage 3+, but this
could cause an impact on the amount of viable tenders received, as
well as higher tender prices that may cause an impact on the
viability of the scheme.
