A private house on a brown field site between existing domestic properties presented us with some unique buildability issues. Due to
acess limitations, all elements had to be brought through a narrow 2.4m wide access from the main road.
The selected structural scheme maximised the width of the site by tying in the existing boundarys without disturbing their Victorian
footings. The structure was then constructed using two steel frames for stability and then simple loadbearing walls. The large floor spans
were achieved by using lightweight timber ’I’ joists which could be handballed onto the site

This project presented a number of challenges for the team. As with any refurbishment project we worked hard to discover how the
existing building was working before we presented solutions to modify it. Along with the existing building investigations, we completed
a comprehensive site investigation to assess the ground conditions on this sloped site. Both the building and site revealed a number of
surprises once analysed fully which went on to heavily influence the final solutions.
We worked to produce a number of schemes at an early stage and illustrated these in sketch form to discuss with the Client. This allowed
both the Client and the Architect to be fully engaged in the structural process and to provide a well coordinated and coherent scheme.

Midway down a single track lane, this woodland retreat presented us with both access and buildabilty issues. Our structural solution had
to allow for small elements to create a larger whole. With a 15m clear span and the inability to get a significant crane to site we looked
hard at the buildability and sequence of construction to inform our solution.
The site constraints lead us to a standardised element with a standardised connection detail which allowed us to create a storey high
Vierendeel truss which sat comfortably within the zones created by the architecture. With all the structure exposed, understanding the
construction tolerances and the sequence meant we were able to develop a series of simple yet effective details to ensure crispness of
finish whilst maintaining ease of build.

We worked closely with our Architect here to produce a fully integrated structure with the lighting. We proposed a structural scheme
which allowed LED lighting strips to be inserted within the structural support fins. We were able to minimise the weight of the structure by
creating a hybrid form which uses the glass for stability. The frame was pre erected off site to ensure build quality and speed of erection on
site.

Cantilevered rear structure Steel portal frame redistributing the loads
This project required some integrated temporary works and clear understanding of the building process. The rear two storey structure
in the rear elevation was required to hover above the glass rear extension. We achieved this by using the mass of the main structure
and cantilevering two steel beams out to pick it up. By inserting a new raft below the building, we were able to redistribute loads evenly
eliminating any differential movement.

As part of Kingston’s Primary Capital Programme we have worked with the design team to provide the school with 9 new classrooms and a
new dining hall structure. The site is surrounded by a number of mature trees and bounded on one side by the railway. These constraints
meant understanding the build sequence was an important part of the design process and a combination of minipiles and regular piles
allowed us to negate the issue of both the trees and the railway whilst retaining a quick and economical build. The conical roof of the
classrooms was created using a series of simple radial timbers in Kertolam timber which allowed the beams to be installed in one complete
length. The dining hall is constructed using an exposed glulam timber frame which provides a column free and attractive double height
space.

Vibro Stone Column Concrete Pads To Support Modules
This project combines a new dining facility for the school and a new children’s centre. Due to the need for the children’s centre to be at
ground floor level, the larger dining area overhangs, creating an interesting structural form. We have used pre-fabricated modules to ensure
a swift build whilst minimising costs. In addition to the modular build, we have used simple ground improvement techniques to reduce
foundation costs.

We are currently working on the scheme for a new sports and entertainment complex at the Harrodian School in Barnes. The school is on
the site of the Former Harrods Sports Club and the original premises have been extended and converted for educational purposes. The
scheme involves sinking the building into the ground to allow the facility to present a minimal elevation to the surrounding properties as the
site is situated on Metropolitan open land. We have completed an extensive desk top study in conjunction with our Geotechnical consultant
to attempt understand the ground conditions as the site is close to a former reservoir and the banks of the Thames. The project is currently
in planning and we hope to begin work on the final scheme in 2012.

The Client came to the design team with a tight site and a need to expand whilst mantaining operations. The Client also had a very hands
on approach to the works but little experience with building.
The existing portal frame shed was erected in the 1970’s on the site of a V1 rocket strike. We came up with a scheme which punctured
the existing structure whilst leaving it mainly unaltered. This gave us the ability to extend the existing footprint within the site boundary
whilst the structure remained 80% occupied. In puncturing the existing structure, we were also able to reuse the existing envelope further
reducing costs.
We worked hard to communicate the structural decisions and processes to enable the Client to engage in the process. This allowed the
structure to influence the design of the building providing a balanced and integrated end product.

Each frame has 2 rows of 2.5mm diameter Microcables supported top and bottom that are arranged in a rhythm of colour. The top member is bolted to steel channel that is already fixed in place prior to frames coming to site. The bottom member of the frame is bolted to the existing balustrade which is cut down in height and the cables are tensioned in sequence to the correct tension. The wires can easily be replaced if required.

Located in Shoreditch, this mixed use development posed some interesting buildability issues within the fabric of this Victorian industrial
unit. After providing a condition survey of the existing building, we worked on producing a structural scheme for a 2 storey roof extension
which respected the existing structure. Small elements were used to create a larger whole ensuring all elements could be brought through
existing doorways. This provided an economical and traditional build which suited its setting and the type of contractor who would carry
out this scale of work.

these to site, undertaken through a standard doorway.
One of the main internal piers removed at ground floor level was heavily loaded - support to this load was provided using a double height
steel goalpost frame, bearing on a new mini reinforced concrete raft founded at basement level.

Site Overview
We are currently involved in producing a structural feasibility report for this new mixed use residential and retail development. In working
closely with the other consultants at this early stage, we are able to offer the client an added value building which represents the integrated
design approach.
Our main input is to consider basement construction techniques which maximise space whilst moderating cost. This issue will be the
difference between a single or double storey basement carpark which will dramatically effect cost.

Part of the Masterplan to redevelop the Bridge House and Marion Court estate off Hommerton High Street, Hackney. This project has all
the classic constraints of an East End site along with the additional problem of being located over the new Chelsea to Hackney Crossrail
line. Lyons O’Neill are currently developing the foundation options to give the Client the ability to understand the technical issues and to
make informed decisions on how best to progress the scheme. Along with the detailed design Lyons O’Neill worked on the desk study for
the site including a historical and UXB search.
The scheme is due on site in late October 2010.

This project involved us working in partnership with a local developer to maximise the usable space on the site of a disused public house.
We looked at various methods of construction to both reduce time on site and the amount of spoil removed. Consideration of heave issues
at an early stage allowed us to programme works permitting heave pressures to relieve during the Christmas break. This allowed us to
remove the anti heave piles below the basement raft reducing both costs and programme time.

Simple cable tensioning springs
7m high carbon fibre gullwing doors The gallery space
Viewed from both within the gallery and from the balcony above, the structure has the opportunity to present two faces. The structure is
essentially all external allowing the internal space to be free of obstruction and ultimately flexible to the curator.
The lightweight box is achieved by suspending the roof members with a series of 1.5mm diameter cables from a simple frame hidden
within the roof lantern. This allowed us to maximise the structural capacity of the sections creating a simple but elegant roof. The cables
were individually positioned through holes in the roof level frame and tied together before constructing the box. Once installed the cables
were draped and pushed through individual clutches to support the roof. Small springs were introduced to the cables to ensure tension was
always present even with variation of loading and construction tolerances. The installation process was prototyped to develop a sequence
of working which allowed the structure to be delivered within programme and budget.
The entrance to the space creates a transitional lobby where a perceptual shift from the V&A proper to the Contemporary program is
allowed to occur. It has been designed to offer different forms of access to the gallery through five seven-metre high rotating screens.
The screens can be reconfigured to the curatorial needs of each exhibition and are clad in reflective black carbon fibre sheeting, a very
lightweight skin more commonly found in aircraft manufacture.

Lyons O’Neill have been shortlisted along with 4 other practices for a new installation in the heart of the City. The sculpture marks a part of
London’s High Street 2012 initiative and will remain in place for the duration of the 2012 Olympic Games. It will stand on a site historically
known as ‘Ale-Gate’, so called because it was the only City gateway open to all. It is hoped the new landmark will underscore the fact that
the City now welcomes, rather than drives away, its neighbours.
We responded to both the temporary nature of the installation and the congested nature of the site by introducing a light touch structure
which can be installed using the minimum of plant and without closing the road. This fully interactive installation can be simply demounted
leaving the site exactly as it was and can easily be reinstalled in another location as a more permanent piece.

This was a winning scheme for the RIBA competition for a set of Kiosks at the entrance to Stratford Station. This Olympic project required
the kiosks not only to perform as a functioning retail unit but also provide a sense of space and for a portal for approaching spectators.
We used a combination of Reinforced concrete and CLT Panels to form this panalised building. The concrete base was extended up to
form a robust skirt and which also acted as a security barrier to the station and the buses which entered the adjacent station. The CLT
panels allowed the structure to be quickly assembled in the space as well as providing a self finishing structure. The use of screw piles for
foundations meant the structure is completely demountable if required.

Basement
Ground Floor Construction
This two storey basement in an in fill site between a number of properties presented a number of challenges. Understanding the context
of the building in relation to the boundaries was key on this project. Having around 20 party wall awards a robust and consistent approach
was required as well as clear and informative drawings. A combination of traditional and innovative grouting techniques were used to
stabilise the ground and retain water during the works. Monitoring stations with trigger levels were agreed with the boundary Engineers to
ensure works progressed safely and without disruption.
RC Boundary Retaining Wall Construction
Lyons O’Neill - Boundary Wall Section Details
Many local authorities now require pre planning structural reports when considering basements. We have produced a number of these
reports and developed a report style which focuses on the process as much as the solution. This is to inform both professionals and lay
Clients our key decisions and to inform the planners of the viability of the scheme.

Site Construction - RC Capping Beam
Architect’s Section
This basement was located on a sloped site with some unique geotechnical issues. Being almost at the natural slip angle for London Clay,
stabilisation of the slope during the works was a key element of the works. Being able to illustrate the issue to the team and Client meant
that the position of the of the swimming pool was altered to provide a much cheaper retaining structure. This process of illustrating possible
solutions meant the Client had an understanding of his building and was able to make informed decisions on the structure. We looked
closely at the build process to help drive out key cost items and to enable party wall awards and planning to be easily achieved.

Temporary Propping Of Existing Ground Structure While Excavation Occurs Steel Frames In, Basement Slab Under Construction
This project required us to tunnel under an existing building whilst the Client was still in occupation. We investigated the build process
through drawing to come up with a permanent structure which also was used as the temporary works. We came up with a series of frames
which were introduced at 1.2m centres on mass concrete bases and underpins. Once these were installed and the slab supported, the
beams were spliced allowing a number of temporary columns to be removed and the spec opened up.

Basement Construction
A more straight forward single basement construction and typical of a number of residential conversions. We looked at the build sequence
here and established it would be cheaper to rebuild the rear extension rather than retaining the structure which was proposed by a previous
Engineer. The savings on temporary works allowed the Client to extend the basement providing greater value a much more usable space.
Again this project required a pre-planning report and construction method statement which we provided at an early stage allowing for a
straight forward party wall and planning process.

Lyons O’Neill Drawing - Section
We continued our work with the Big Basement Company on this 2-Storey basement on a constricted site in Chelsea. The scheme called
for demolition of the structure whilst only retaining the facade which presented a difficult set of temporary stability scenarios. We worked
closely with the Big Basement Company to come up with a sequence of construction which allowed the permanent floor structure to act as
both temporary and permanent works. This created a saving not only in cost of temporary works but also in time on site. The construction
sequence was illustrated to both investigate and explain the process and was used as part of the party wall submission accelerating the
process.
The high water level in the area meant we adopted a hybrid foundation solution to maximise the space available to the client whilst
maintaining stability of the surrounding structures. The solution involved a traditional underpin to the upper basement level which allowed
a full width basement and then progressing to a secant mini-piled wall solution below the water table. This secant piled retaining wall
structure penetrated into the clay strata below the site which allowed us to excavate below the water table in dry conditions.

Our challenge on this project was to create a complex 3 dimensional form with simple 2 dimensional elements. The centrepiece of the
scheme is the ‘Boiler Suit’, a facade surrounding the boilers that power the hospital. The final facade is formed of 108 tiles made of 40km
of woven stainless-steel braid.
At night the Boiler Suit is illuminated ‘to provide a distinctive welcoming beacon for staff and visitors arriving at the hospital’.
The scheme also includes widened pavements, a one-way traffic system with designated drop-off points, new signage, CCTV, lighting and
a new build shop.
The project has been funded by the Pool of London Partnership, Guy’s and St Thomas’ Charity and the Friends of Guy’s Hospital.

We are currently working on the scheme for a new sports and entertainment complex at the Harrodian School in Barnes. The school is
on the site of the Former Harrods Sports Club and the original premises has been extended and converted for educational purposes. The
scheme involves sinking the building into the ground to allow the facility to present a minimal elevation to the surrounding properties as the
site is situated on Metropolitan open land. We have completed an extensive desk top study in conjunction with our Geotechnical consultant
to attempt understand the ground conditions as the site is close to a former reservoir and the banks of the Thames. The project is currently
in planning and we hope to begin work on the final scheme late in 2011.

It should feel slightly daring to be in this space; not dangerous but a definite shift from normality, a juxtaposition of the familiar pushed into
a new context. Uninitiated onlookers will wonder what it is at first: purely a sculpture or something more? On their daily commute they can
see how it changes in the light: reflecting conditions and giving new perspectives. They will become aware it is occupied which can only
add to the intrigue. Guests will become more comfortable over time as they absorb their new surroundings. Initial concerns about exposure
give way to the possibilities offered by their temporary home. How often will you get to lie in bed as the sun rises over the London skyline
all around you? Or lie in darkness and observe the city at night?

Lyons O’Neill were commissioned to produce a condition report on this grade II public house constructed in the early 19th century. Our
study soon revealed that the structure, which appeared to be uneconomical to refurbish, could be made robust by some simple yet
effective remedial measures. This allowed our client to purchase the building with the confidence he could redevelop the residential space
above.
As part of the refurbishment work we developed a structural scheme which allowed a new access to the flats and toilet facility to be
created for the pub whilst it still operated. This was achieved by forming a lightweight structure which spanned across the roof of the
kitchens to the pub sitting purely on the external walls. The link between the pub and their new facilities will be switched over during a
fortnight of light refurbishment works to the pub allowing maximum trading time.

This was a winning scheme for the RIBA competition for a set of Kiosks at the entrance to Stratford Station. This Olympic project required
the kiosks not only to perform as a functioning retail unit but also provide a sense of space and for a portal for approaching spectators.
We used a combination of Reinforced concrete and CLT Panels to form this panalised building. The concrete base was extended up to
form a robust skirt and which also acted as a security barrier to the station and the buses which entered the adjacent station. The CLT
panels allowed the structure to be quickly assembled in the space as well as providing a self finishing structure. The use of screw piles for
foundations meant the structure is completely demountable if required.

Our aim was to provide a simple form which respected the low lying setting and did not dominate the horizon. The site’s geology means
that the West bank has better founding conditions than the East pushing us towards a solution supported from one side only. After drawing
up various options it became clear that completely supporting from one side would provide too dominant a form which was something
we were working against. As a result we looked at a simply supported solution and tried to refine them to provide a slender elevation. We
settled on a simple parallel chord truss form and worked to reduce its elevation. To improve its depth we introduced a column on the West
Bank to balance the bridge’s forces and allow us to present a slimmer elevation. The form is tried and tested and is made up from simple
elements requiring low levels of fabrication. To reduce the dominance of the structural members we further refined the truss by using the
longitudinal cladding to laterally restrain the main members against buckling. This will allow us to further reduce their cross section and
therefore the bridge’s weight and cost.

Aldgate, London

Lyons O’Neill have been shortlisted along with 4 other practices for a new installation in the heart of the City. The sculpture marks a part of
London’s High Street 2012 initiative and will remain in place for the duration of the 2012 Olympic Games. It will stand on a site historically
known as ‘Ale-Gate’, so called because it was the only City gateway open to all. It is hoped the new landmark will underscore the fact that
the City now welcomes, rather than drives away, its neighbours.
We responded to both the temporary nature of the installation and the congested nature of the site by introducing a light touch structure
which can be installed using the minimum of plant and without closing the road. This fully interactive installation can be simply demounted
leaving the site exactly as it was and can easily be reinstalled in another location as a more permanent piece.

Lewisham, London. Properties were transferred from Lewisham Council in a large-scale voluntary transfer on 3rd December 2007 following
a positive ballot of all tenants. It is a new organisation, developed for this area, and has no connection with any other Housing Association.
On winning the framework bid Lyons O’Neill met with PCHA to discuss their brief and to determine whether there were any items we could
expand on which we could add value too. We quickly establish a need to take a global view of PCHA’s properties and database of issues.
Little information regarding the properties was transferred with the sale from Lewisham so PCHA were essentially starting with a clean slate.
Most of the properties sent through were suffering from movement and damage as a result. On receiving the first batch of properties to
review we undertook a desktop search on the properties to see if there were any environmental or historical land issues that may have been
an issue. It was quickly established that the majority of the properties were situated on Clay which instantly pointed to shrinkage and heave
issue. In addition to this our historical research showed that the properties in the main were constructed as part of the ‘Homes for Heroes’
programme after the first world war.
