Kensington High Street
Project Overview
Scudder was appointed by St Edwards Homes to demolish 375 Kensington High Street
(Charles House). The former Inland Revenue offices stood at 10 storey high, plus
basements, with a footprint of 50,000sqm. The site is bounded by Kensington High Street
with a prestigious London hotel opposite, smart residential streets and a main railway
line. Success of the demolition works was such that the Carey Group where then awarded
further works drawing on the expertise of both our both Civil Engineering and Concrete
Structures divisions. The demolition phase of the project was shortlisted in the Specialist
Awards 2012.

More Information
The demolition of the building required meticulous planning, and involved different
demolition techniques for each section of the building. 80% of the exterior of the
building was encased with monarflex sheeted independent access scaffold, reducing
dust and noise transmission. The rear of the building was left clear, allowing long reach
remote demolition machines to demolish two of the rear wings and the central spine.
The remaining wings (adjacent to the railway and public highways), were simultaneously
demolished, top down, using 7 tonne demolition spec machines fitted with pulverisers. In
order to remove the basement, a pressed sheet pile retaining wall system was installed
tight to the boundary, during the demolition phase. Vibration monitoring with audible
and visual early warning alarms, was installed to ensure the gas and water mains were
safeguarded at all times.
Due to the close proximity of live railway lines, much of the work required close liaison
with Network Rail, carefully planning and communicating site activities in advance to
ensure smooth progress.
With the successful completion of Phase 1, Careys was awarded the second phase of
works.

The British Museum
Project Overview
Careys scope of works is for the construction of the reinforced concrete substructure for
the World Conservation and Exhibitions Centre at the British Museum. The sub-structure
is approximately 18m deep and has 5 levels with a sub floor providing space for lift pits
and motor rooms. The site is located within the bounds of the existing British Museum
complex. The works area is bound by retained buildings on 3 fronts making the site a
very challenging footprint to work on. Prevention of damage to the existing building and
exhibits within meant that noise and vibrations were monitored and minimised.

The British Museum is a world leader in the conservation and display of objects from
across the globe. To ensure it can continue and grow its important role through the
twenty-first century it has taken the opportunity to expand into this new building which
has been created to provide a light finish of specially-produced glass and traditional stone
to sit well and blend with its grade I listed surroundings.
The new Centre will provide:
• dedicated gallery for special exhibitions • conservation and science facilities
• a collections’ management hub • world-class stores for the study collection
Although we have managed noise and vibration issues on many of our sites we recognise
that the concern on this project is such that a higher degree of understanding is required
and have therefore employed the services of a specialist, SENSONICS, to assist us with
the development of our elimination, management and monitoring strategy.

The Seneca site’s access and perimeter road was modified to suit the revised traffic
management requirements of the facility, with a digitised weighbridge system installed
to record the weight and origin of each delivered load. Additional pedestrian and cycling
access was also constructed, together with car parking for 50 vehicles.
The refurbished building gained BREEAM excellence standards, with an integrated greywater harvesting system installed. 5m high in-situ reinforced concrete retaining walls
were cast to create material storage and segregation areas. The elevated 40m long
picking line area is adjoined by high quality staff welfare facilities. Eight designated
material collection bays sit below the picking line,
allowing operatives to manually select and divert different material types into collection
bays via metal hoppers, located adjacent to the picking line conveyor belt.
A series of flip-flow screens were installed to separate out varying sizes of fines, with
large magnets to takeout the metal rich items. Once materials have been separated out,
they are bailed and stored ready to dispatch for reprocessing or remanufacturing.
The facility also benefits from a rail siding which spans the full length of the 175m long
site; with two parallel lines running both inside and outside. The rail siding is scheduled
to go live early in 2012.

tarmac surface for the external parking area was added with the footpath laid with resin
bonded gravel using Addagrip.
An earth reinforced retaining wall and service yard were also constructed as part of the
works. Part of the surface of the Square was laid with a red tarmac (Europave) with white
lines then stencilled on it to create the event space for basketball and other sports. In the
Event Square, precast concrete benches and steps units were constructed. These works
had been carried out to such a high level of quality and care that Careys were latterly
awarded a further commission by the client on the same site.
Careys Concrete Structures division oversaw the building of the post-tensioned (PT)
concrete slab in the office areas and a reinforced concrete slab in the core area for
Building 6. The building benefits from a central insitu concrete core which acts as
a cantilever from undercroft level and provides the lateral stability for the building.
Horizontal loads from the façade are transferred through the floor plate back to the core
and then down through the walls to the foundations.

More Information
A particuarly complex project the Tesco and Careys teams were involved in was the
development of a new store and housing in Seaton. The site was previously a holiday
camp and was low lying with a planning requirement being that the site footprint must be
raised. A scheme was devised to raise the levels with imported dredged materials that
were pumped ashore via a 1.6km pipeline. The materials were discharged into purpose
made temporary lagoons from where the water was removed and material then excavated
and distributed around the site.
The sand was delivered in 14,000m3 boatloads which took 3 hours to pump onto the
site and return the 30,000m3 of seawater. In total around 240,000m3 were received and
placed by Careys in two weeks. Once the surcharge periods were over half that volume
had to be moved again and the final formation trim to all areas. This was carried out by
GPS controlled blades to a +/-30mm tolerance which given the material was sand was
very tight.

Careys works were across two structures the first of which is a large existing inlet
pumping chamber, some 20m deep with a plan area of around 1200m2. This structure
underwent large scale modification including the demolition of load carrying elements and
sequential reconstruction of new load carrying elements.
The second structure is the existing seal Weir chamber which consisted of a deep
sequence of large culverts. Careys operations included the complete demolition of the
culverts followed by the construction of a new chamber measuring some 12m in depth
and with a plan area of around 900m2. The sequencing of the external wall pours along
with the complex internal wall arrangement was key to the successful completion of the
structure within milestone dates.
Careys brought real client benefits to the project by being able to resequence the buttress

More Information
Careys installed more than 500t of steel founded on piled foundations to erect the frame
of the buildings. On the Olympic Park the Energy Centres are steel framed structures
founded on piled foundations incorporating heavy insitu ground floor slab and composite
concrete slabs to first floor, mezzanine level and roof to accommodate heavy plant
installations. The structure is clad in a waterproof membrane with an outer Corten
shroud to soften the impact of the building size.
Scudder was tasked with the partial demolition and enabling works for the conversion of
the historic Edwardian mill. The main works included the strip out and opening up of the
north side of the mill structure to host the biomass plant whilst retaining the floors in the
south side and creating new stairwells and liftwells.
Logistically both projects had great degrees of difficulty due to their close proximity
to Network Rail lines and the CTRL box as it passes through Stratford. Considerable
amounts of liaison between Careys, Network Rail and CTRL was required together with
technical submissions prior to any works commencing. Additionally as the Olympic Park is
considered a high security risk, access and egress for plant, materials and operatives was
a very structured and controlled process.

Heathrow Airport
Project Overview
Careys first appointment was on an Enabling and Main Works contract relating to general
groundworks for the construction of a new control post (CP5), sitting alongside the
existing live control post. This project took place part airside and part landside in a
live airport environment allowing Careys to work innovatively by carrying out vacuum
excavation around live services. A further Careys appointment at Heathrow was Terminal
4 Baggage Works and involved the extension of the existing baggage facility; Reclaim 8
by adding a new baggage conveyor and by removing the existing blast screen.

building works included foundations, services, drainage foundations for blockers and
barriers (to control traffic) all within the airside of the
airport. Additionally Pavement Quality (PQ) slabs, 350 thick with lean mix underneath
were cut by diamond cutting saw. Foundations were excavated by hand-digging due to
chartered and unchartered services/ducts present at Heathrow. A stormwater interceptor
was installed along with heavy duty aco channels.
Working in an airport environment carries a number of unique challenges which the Carey
team are adept at tackling, from complying with the latest BAA requirements in health
and safety and asset management to working on busy live sites and night time working,
the team at Careys are proud to consistently deliver undisputable levels of service.
The dedicated and specialist team provides the highest quality of service and continues to
receive commissions from Heathrow Airport and has now recently commenced works with
Vinci at Gatwick Airport.

Prior to commencement, liaison took place with the police, local public transport,
statutory services providers and other interested public bodies. Careys provided traffic
management throughout the course of the new roadworks. The scope of works also
included first phase of the site infrastructure to serve the new John Lewis distribution
centre with extensive earthworks involving cut and fill and over 1.5km of combined
services trench, 500m of deep foul drainage, over 2km of polyethylene storm water
drainage and ductile iron water main.
The contract was divided into two phases. Phase 1 involved the construction of two
thirds of the length of the two cast insitu RC pedestrian underpasses. These works then
had a one lane road and central reserve lain on top, as part of the 1.5km road widening
of the A421. In addition, the new dual carriageway (Fenn St) and roundabout was

More Information
The remaining part of the project comprises of a 2 storey retail shell with an additional
4 storey residential block constructed in lightweight steel frame above. One of the
key issues was that the site was above and alongside Wembley Central Station which
accommodates both Network Rail and London Underground operating companies. Careys
had to submit documentation and seek permission prior to any works commencing. Both
transport companies activities remained operational throughout the works.
In addition, the site constraints involved working in a very busy city centre environment
necessitating the need for careful consideration of public interfacing at site entrances and
thoroughfares. Agreement was reached with the local authority highways engineers, as
to the measures that had to be undertaken for maintaining the vehicle and pedestrian
thoroughfares past the main site access points.
There were also restrictions on noise and dust pollution. Careys had to carry out noise
suppression measures, putting acoustic barriers around noisy plant and restricting noisy
working periods to set times of the day to minimise the impact on the local residents and
businesses.

More Information
A ‘grey water harvester’ drainage system is used through-out the building for the toilets.
Careys also introduced rain water interception tanks which enabled the fire services to
use this water for training purposes rather than using filtered water.
A Contiguous Piled Retaining wall on the Northern side of the site was built to maintain a
footpath running alongside an existing store. The foundations for this were CFA-piled to
a maximum depth of 22m.
The Training and Service Yards were constructed of traditional reinforced concrete slabs
with a brushed finish. Block paving was installed at the front car park of the fire station
and apartments. Soft landscaping was designed to reinforce security and privacy and
support footpaths to prevent shortcutting and erosion of edges.
Work on the highway was carried out under a Section278 Agreement with the Watford
Borough Council to realign the existing road and footpath to accommodate the fire
engines access and egress. This included altering the traffic lights to accommodate for a
“Green Wave” traffic signal at the junction, to give priority to the fire appliances as they
approach the traffic signal.
