Webb Yates Engineers Bristol by Webb Yates Engineers

â&#x20AC;&#x2DC; Webb Yates are a joy to work with. They are skilled, committed and inventive. Their attitude to creative design collaboration mirrors our own. They are always willing to put in the time and effort to push the solution beyond the normal and the obvious and achieve something really special.â&#x20AC;&#x2122; Alan Stanton, Stanton Williams -2-

PHILOSOPHY The pursuit of sustainable and efficient structures creates economically rational projects with inherent beauty Webb Yates Engineers was established in London in 2005 with the aim of creating a practice that combines imagination with technical rigour to create artful and inventive structural designs. We have since expanded to other cities and are excited to have recently opened our new office in the superb city of Bristol. Central to our philosophy is an enjoyment of the collaborative creative process. Our team relishes working closely with architects, designers, builders and other engineers. We seek to develop flourishing working relationships and where appropriate, challenge boundaries and find fresh approaches. A love of material possibilities informs the best of what we do. As well as mainstream construction materials, such as timber, steel and concrete, we work with a wide selection of other materials which has expanded our knowledge and exercised our ability to

approach unusual problems and solve them in a practical and considered way. Webb Yates Engineers are keen to add to the green culture already established in the South West; we take sustainability seriously and believe that the built environment has a key part to play in this. Webb Yates Engineers has a long established track record working on low carbon building designs and making use of natural building materials where possible. Our work with stone is one of many vindications of our approach. After working on our first stone project 6 years ago we have become one of the UKâ&#x20AC;&#x2122;s top stone engineering consultancies. We are attracted to stone because it has a very low ratio of carbon footprint compared to its strength. Our collaboration with The Stonemasonry Company has led to the development of innovative techniques and engendered opportunities to experiment and push boundaries.

We believe that a deep understanding of the process of making things is essential to good design. Working through the act of building is the heart of how we find efficient structures. We like to work with specialist fabricators and manufacturers so that we understand how things are put together. Whether you are an architect, contractor or developer, Webb Yates Engineers always begin projects with pen and paper, rapidly outlining key options for discussion and evaluation.

THE TEAM Webb Yates Engineers are a 60-strong practice with offices in London, Birmingham, Bristol and Dubai. We are an enthusiastic, close-knit team dedicated to the art of engineering. Engineering is an intellectually challenging but tremendously rewarding field of endeavour and vital for a country that wants a more balanced economy. We therefore seek to

give engineering a more prominent and visible role in the development of beautiful and rational architectural engineering design. We give lectures and tutorials at Oxford Brookes University School of Architecture, the University of Kent School of Architecture, The Architectural Association, and The Bartlett amongst

others. We also take part in cultural and industry events and exhibitions curated by institutions such as the Victoria and Albert Museum and The Architecture Foundation. We take part in Club Peloton sponsored cycles such as pedElle and Cycle to MIPIM as well as organising regular charity events ourselves. Over the

THE FUTURE

The vision of clients and the imagination of architects push us into new areas that bring out the best in our practice. Issues such as new housing, reuse of existing buildings, efficient use of resources and wellbeing in the workplace require more than a standard response if we are to create environmentally and socially sustainable buildings that people love. As our horizons expand, so do the scale and complexity of the commissions we are involved with.

Typifying our approach, we are currently working with the University of Bristol to develop a method of construction which exploits the benefits of both timber and concrete frames. Timber Concrete Composites (TCC) utilise a timber frame with composite concrete floor plates (either cast in-situ or pre-cast) to maximise -5-

thermal efficiency whilst minimising embodied carbon. The result is a beautiful interior that expresses both materials, provides good acoustic separation, and allows for future adaptability.

01 / Hackney Marshes Centre Providing changing rooms for Hackney Marshes sports pitches, this award-winning community hub also includes a cafe, teaching space and office accommodation. The architects were looking to respond to the surrounding green urban environment in both the elongated form and the rugged industrial external materials. Internally the structure is exposed throughout and defines the architecture. The resulting spaces have clarity, hardwearing finishes and provide an economic

structure appropriate to this type of building. The external cladding is principally weathered steel panels and gabion walls, chosen for robustness and to reflect the buildingâ&#x20AC;&#x2122;s surroundings. The gabion walls - recycled concrete from a demolition site in Wembley - are both vandal resistant and provide a framework for climbing plants. That the project won the London Planning Awards for Best Project Five Years On is a testament to the graceful ageing of the building.

02 / New Oak A private house with a standardised timberframe system and a feature oak roof structure combines the benefits of a prefabricated system alongside the stunning visual effect of a wellcrafted exposed structure. The floors are of trussed joist construction and the walls are constructed with OSB sheathed stud.

The factory fabricated units function as stressed skin diaphragm elements to support the large cantilevers at the eaves. The main feature of the double height central living space and gallery is a stressed skin roof supported on a lattice of new oak beams. This needed to support itself in a clear span from the walls on all

four sides. One side of the roof was propped against the other with thin timber poles. The location of these poles was determined from stress analysis of the strapped rafters. The roof was assembled on the ground on site and then lifted into position.

03 / Cowley St Laurence This project consisted of additional education facilities for this primary school in north west London. The new building infills an existing space between buildings and provides a new entrance space to the school. Cladding to the building includes a facade made entirely from Lego bricks.

To minimise disruption to existing live service routes, the steel and timber framed structure spans across the existing space. At first floor level, a storey deep steel and timber truss spans behind the glazing as a structural stability element.

Throughout the project, the school was kept fully open requiring the careful phasing of works with minimal intrusion into the existing building fabric.

04 / Fuente del Jarro This two-storey factory building designed for very heavy occupancy loads is an example of how efficient use of materials can be achieved by an elegant structural solution.

The use of flat tension plates to the underside instead of clevis connected tendons reduced the height of the truss over the travelling crane by 100mm shortening the building.

Splitting the trusses into V shapes reduced the span of the floor slab. The top chord of the steel structure is buried in the concrete so the two elements are acting compositely. These made a 30% saving in steel and reduced the quantity of suspended concrete in the building by 50%.

05 / Lâ&#x20AC;&#x2122; Argens Bridge This 30m span pedestrian suspension bridge was designed to be very lightweight and low impact. The impossibility of access for a mobile crane meant that the bridge needed to be manually erected. This constraint drove every aspect of the design. It was fabricated in 15 sections made up of a perimeter frame with crossing bars at varying angles forming

the shell. The sections and supporting cables were transported to the South of France, near Toulon and assembled using a zip wire to haul them across and fix them in place one by one.

flexibility of the supporting cables meant that during construction the bridge form evolved as each new section was installed.

The mesh infill on the balustrade stiffens the bridge and makes every element act as part of the primary structure. The light weight of the structure and

06 / Wimbledon College of Art A new sustainable studio building for Wimbledon College of Art was designed as a simple, flexible enclosure with excellent natural light and ventilation. The clientâ&#x20AC;&#x2122;s ambition was to create an exemplar building achieving BREEAM Outstanding. An exposed timber and concrete frame was developed in close

collaboration with the architect and services engineer. This provided a structure with large thermal mass which in turn enabled the building to be naturally ventilated. The combined effect of an excellent envelope performance combined with other sustainability measures such as orientation, natural

ventilation and renewables gained this the second highest BREEAM score in the world as part of its design stage assessment. A truly holistic achievement.

07 / Mann Island Webb Yates Engineers undertook concept design and structural analysis for these challenging concrete framed buildings on Liverpoolâ&#x20AC;&#x2122;s historic waterfront. The project consists of two blocks of residential units reaching up to 14 storeys high with retail space at ground floor level. The blocks are of an angular

form, designed to appear as solid masses hovering above the ground with the retail units as lightweight, transparent spaces. To enhance this effect, the residential superstructures cantilever out beyond the retail areas by up to 16m. The structural design had a significant number of constraints from the overall architectural form, column

coordination between the various levels and usages, and window locations. The structural solution developed to overcome these constraints included multi-storey shear walls and concrete vierendeel truss sections, together with more traditional concrete walls, beams, columns and slabs. For the analysis of the structures we undertook a powerful finite element

analysis of each block as a single entity including taking account of creep effects, shrinkage, axial shortening and build sequencing.

08 / Ada Street This mixed-use development situated at the south end of Broadway Market is comprised of 6 apartments above retail units. It incorporates an insulated render system, allowing a high performance thermal envelope to act as pitched roof, wall, window reveal and sill without a gutter or coping, although Conservation Area height requirements imposed a

part flat roof. Internally, exposed block-work, precast concrete soffits and power-floated floors were combined to meet acoustic performance without the need for plasterboard ceilings or raised timber floors. This saving permitted the introduction of under floor heating and 5amp lighting circuits.

09 / Bavaria Road This project involved the installation of a mezzanine floor within a large double height studio flat. The existing building was a Baptist church and our clientâ&#x20AC;&#x2122;s flat sat on the second floor beneath a large, original timber trussed roof. Initially it was supposed that the mezzanine would sit on columns, but as there was little load bearing structure beneath and the architect was keen not to have a

column, we developed a hanging solution. Every element of the finished work is structural. The balustrade is the beam spanning from the wall to the drop rod. This is formed with a 36mm laminated ply balustrade. The ply floor deck is the compression flange of a stressed skin floor. The risers and goings on the folded stair are the diagonals on the truss that supports it.

10 / University Hospital Bristol This art installation by renowned international architects, Studio Weave, is intended to function as a visual and acoustic barrier for the entrance atrium of the new childrenâ&#x20AC;&#x2122;s wing at UCH Bristol. Whilst it can be seen instinctively that a trumpet shape like this is anticlastic and will stay taut in space, it was critical that a precise

form was found where all of the cables were tight enough at once to support the baffles without significant deflection. We used a pair of stockings to find the initial shape, and a computer analysis package to determine the stresses in the cables.

This new residential building is slotted into a Victorian terrace in Dalston. It comprises six storeys of flats above ground and a single storey basement flat with lightwells to the front and rear. A comprehensive understanding of the materials involved was required as well as careful detailing in order to leave the loadbearing elements exposed.

The concrete basement was constructed in underpins of various shapes and sizes to fit with the structure above. The superstructure is cross-laminated timber (CLT) panels spanning up to 6.0m with various voids for the stair and services. The staggered masonry faรงade is decoupled from the rest of the building to allow it to move separately. Each of these materials serves a different purpose; acting and moving in their own way but together they form the seamless combination of structural form and architectural vision.

12 / Hill House Kent This private house is on a former garden nursery site in the heart of the Kent countryside. It was designed to reflect environmental sensitivities and be rooted in place. The striking folded timber roof form is heavily insulated and finished in black zinc. The use of vapour permeable layers from the natural coated birch plywood through the vapour permeable anti-racking boards to the external vented cladding cavity have produced a fully breathable construction. Separating the retaining structure from the building was the key and using re-cycled excavation material as a retaining wall kept the carbon footprint low and the project on

budget. Use of geo grid soil reinforcement to form the hole in the ground meant that fill was retained on site and very little concrete was used. The foundations were small pad footings, the ground floor is timber. Foul and surface water run off are dealt with in a packaged treatment plant on site.

13 / Virginia Water Visitor Centre This visitor centre overlooks Virginia Water, a man-made lake, within Windsor Great Park. It replaced a snack van with park ranger facilities and a cafĂŠ.

The impressive 8m cantilever supports a 12m span roof within a depth of 200mm. This has been made possible by the incorporation of slots in the canopy roof that relieve wind pressure and snow loads.

The building is predominantly timber with steel framing incorporated at key points for additional strength.
