2. o Well served by public transport, there is
access to DLR, national rail, river boat
and several bus routes which provide
quick transportation to central London
and surrounding areas.
o Town centre provides several facilities
including restaurants, pubs and shops.
o Local attractions include Greenwich
Market, Cutty Sark and Greenwich Park.
o Numerous schools and colleges nearby
including University of Greenwich.
o Short distance from Canary Wharf and
the O2.
Creek Road - Site Location
3. Creek Road – Townhouses
o Townhouses located to south of site are
family homes which form the boundary
to a nearby park.
o An intimate mews space is created
between theses houses and the rest of
the development.
o Quite streetscape will provide
pedestrian route to town centre with car
parking for owners.
4. Concrete Formwork Construction
o Technique used by contractor Bouygues in
the construction of Creek Road, Greenwich
involved using a combination of a bespoke
vertical panel system specifically
manufactured in France for Bouygues UK
alongside a lightweight horizontal panel
system.
o Both these systems are modular however
they are different to tunnel form systems
which requires a very specific building
typology.
o This method allows for the construction of a
more aesthetically pleasing design whereas
tunnel form construction is suited to a
repetitive stacked design.
o The construction sequence must be split,
casting vertical and horizontal elements
separately (generally by core) as the
systems are not designed to be used
simultaneously.

5. Concrete Formwork Construction
o A crane is essential to the construction
sequence as it is needed to lift the formwork
into a vertical position for it to be restrained
using props.
o Site operatives can then fix reinforcement
and ties against the erected formwork.
o If services/openings are required they can
also be accommodated at this stage.
o The opposing face of the formwork is then
positioned at the correct distance by using
wedge clamps which will also hold the two
panels in place.
o Concrete is then poured and once it has
hardened sufficiently the formwork is
stripped, easily cleaned and moved to the
next position.

6. Concrete Formwork Construction
o The process of positioning and setting up a
full rig can take the majority of a day.
o If complete and there is adequate time left to
supervisor a pour the concrete can then be
cast.
o The concrete is left to harden and set which
can take up to 3-4days, once set the
formwork can be struck and positioned into
its next location. This process is to be
repeated until all vertical members in the
core are cast.
o Recent innovation in formwork has led to the
development of several different types of
small lightweight modular systems that offer
versatile formwork solutions on site including
lightweight horizontal panel systems.

7. Concrete Formwork Construction
o The unique feature of using the Creek Road
construction technique was that all external,
party walls and cores were cast in-situ as
shear walls.
o This enabled the construction team to install
windows and curtain walling to form an
effective watertight seal allowing the first fix
to commence at an earlier date than would
have previously been expected.
o Routing of services are of utmost importance
early in the design process, mistakes can be
time consuming to rectify.
