Client: London Wall Place Limited Partnership

Steelwork lies at the heart of the London Wall Place development. It was decided early in the design process that the optimum superstructure solution for both buildings would be steel frames with concrete floors and concrete cores.

“The scheme’s main challenge was to provide a solution for the buildings that could maximise the built floor area, while responding to the many constraints imposed by existing site conditions, planning views and rights of light,” says WSP Director Stephen Jackson.

“This resulted in a structural form with heroically long cantilevers, long span transfer structures and complex geometry to create the building set-backs at the upper levels. This could not have been achieved without the use of steel.”

The largest transfer structure within 1 London Wall Place is 2m-deep and weighs 72t.

The judges say the use of steel has been instrumental in enabling the two buildings to cantilever out over the existing road. A 5m deep mega-truss at level 2, with enormous steel members passing through it, offers the opportunity for a highly unusual new dining space.

SSDA 2018: Two St. Peter’s Square, Manchester

Two St. Peter’s Square is a new build, Grade A office space in the heart of Manchester city centre, consisting of 12-storeys above ground and two basement levels.

As the SSDA awards celebrate their 50th year of recognising the best of what the UK steel construction industry can achieve, we celebrate that 77% of the projects feature STRUMIS customers. In this post we will be celebrating William Hare’s involvement in the Two St. Peter’s Square Manchester project.

Two St. Peter’s Square, Manchester

Architect: SimpsonHaugh

Structural Engineer: BuroHappold

Steelwork Contractor: William Hare

Main Contractor: Laing O’Rourke

Client: Mosley Street Ventures Ltd

The project occupies one of Manchester’s prime city centre locations, opposite the Civic Centre and facing both the Grade I listed Town Hall and Grade II listed Central Library.

The high civic importance, heritage and visibility of the site resulted in an intricate and challenging planning context, demanding a high-quality building.

“Only by using cellular beams could the 18m spans be accommodated while maintaining the required floor-to-ceiling heights,” says SimpsonHaugh Partners Architect Simon Critchley.

The use of a structural steel framing solution was a key element in the project’s success as Laing O’Rourke Project Manager Tim Brown says: “The obvious win was speed of procurement and erection, as the client had a deadline to get the building open in order to secure a Blue Chip anchor tenant.”

“Technically, by using steel the designers were also able to create a large double-height main entrance for the high-end reception area.”

Summing up, the judges say this scheme of new Grade A offices in the heart of Manchester’s civic centre responds to the challenge of this site of prime importance. Not only does the glazed stone tracery respond appropriately to the location, but the elegant steel-framed building with 18m clear spans provides flexible accommodation highly attractive to tenants.

SSDA 2018: Somers Town Bridge, London

Crossing the Regents Canal in London, Somers Town Bridge meets the structural demands with the very minimum of materials.

As the SSDA awards celebrate their 50th year of recognising the best of what the UK steel construction industry can achieve, we celebrate that 77% of the projects feature STRUMIS customers. In this post we will be celebrating S H Structures Ltd.’s involvement in the Somers Town Bridge project.

Somers Town Bridge, London

Architect: Moxon Architects

Structural Engineer: Ove Arup & Partners Ltd

Steelwork Contractor: S H Structures Ltd

Client: King’s Cross Central Limited Partnership

Designed for cyclists and pedestrians to cross from Camley Street into King’s Cross Central, the Somers Town Bridge is a landmark redevelopment project.

It spans 38m, weighs 52t and it is only 1,100mm deep at mid-span and 400mm deep at the ends.

In keeping with the Victorian heritage of the area, the bridge is unadorned and streamlined, focusing attention on extremely detailed and precise craftsmanship and high-quality materials.

A sweeping ramp leads people up to the bridge and over the water with an elegant parapet transitioning from planed hardwood to stainless steel.

Every single element of the bridge is said to have a structural meaning and function. It was designed so no longitudinal stiffeners would be needed, simplifying the structure as well as reducing fabrication complexity and cost.

The curved plates connecting the web and deck plates are an example of design efficiency. The restraint that u-frame stiffeners provide to the top flanges in compression is significantly undermined by flexibility of the web-to-deck connection when, typically, both plates are connected with a sharp angle. Using curved plates eliminated this flexibility and increased the efficiency of the system.

In summary, the judges say a sweeping ramp leads up to this almost impossibly slender steel bridge. Designed for pedestrians and cyclists, the bridge improves access into King’s Cross Central, a landmark redevelopment project. The simplicity of its unadorned and streamlined form focuses attention onto the bridge’s high‐quality materials and precise craftsmanship.

SSDA 2018: The Greenwich Peninsula Low Carbon Energy Centre

The Greenwich Peninsula Low Carbon Energy Centre is the largest new build residential heat network in Europe, saving over 20,000 tonnes of carbon every year.

As the SSDA awards celebrate their 50th year of recognising the best of what the UK steel construction industry can achieve, we celebrate that 77% of the projects feature STRUMIS customers. In this post we will be celebrating Billington Structures Ltd.’s involvement in the Greenwich Peninsula Low Carbon Energy Centre project.

The Greenwich Peninsula Low Carbon Energy Centre

Architect: C.F. Møller

Structural Engineer: Price & Myers

Steelwork Contractor: Billington Structures Ltd

Main Contractor: Kier Group

Client: Knight Dragon

From conception, the energy centre project was developed with innovation and creativity as a central theme.

An important part of the structure is the highly distinctive flue tower, measuring 3m x 18m on plan and 49m tall, which houses the equipment serving technically advanced boilers capable of heating the thousands of new homes and businesses in the North Greenwich peninsula.

The cladding of the 49m-high stack tower unites sophisticated engineering and complex optic research to create an impressive sculptural concept on a huge scale. The unique cladding is formed of hundreds of triangular panels – each the height of a London bus – that fold and flow across the surface of the tower.

“Fortunately, the tensile strength of steel coupled with its ductility made it the obvious choice as it allowed us to create a strong but slim and highly perforated structure.”

Price & Myers designed the main building and tower to be structurally independent, to avoid the effects of cyclic loading and fatigue on the tower affecting the main building.

The flue tower is formed from five 49m tall latticed girders, connected by a series of raking beams and bracing on the main east and west façades.

A total of 345t of galvanized steel was erected for the flue tower, which consisted of five main cantilever frames, each formed from three 16m high by 3.15m wide sections spliced at third points on-site and placed 4.5m apart. These were connected together with interleaving diagonal secondary members fixed to both chords.

The prefabricated trussed girder sections were the largest frames ever to be hot-dip galvanized by Worksop Galvanizing. The frames were double-dipped corner to corner in a zinc bath with only millimetres to spare at each end.

Bespoke lifting brackets were designed and supplied by Billington to allow accurate control by the galvanizers during lifting and turning for the second dip.

SSDA 2018: Four Pancras Square, London

Featuring a weathering steel exoskeleton, Four Pancras Square is the last of six new commercial buildings within King’s Cross Development Zone B.

As the SSDA awards celebrate their 50th year of recognising the best of what the UK steel construction industry can achieve, we celebrate that 77% of the projects feature STRUMIS customers. In this post we will be celebrating Severfield’s involvement in the Four Pancras Square project.

Four Pancras Square, London

Architect: Eric Parry Architects

Structural Engineers: AKT II and BAM Design

Steelwork Contractor: Severfield

Main Contractor: BAM Construction

Client: King’s Cross Central Limited Partnership

Situated on a prominent site, Four Pancras Square demanded a strong identity that resonated with the site’s industrial heritage. This was encapsulated in Eric Parry Architects’ competition-winning design, which features an expressive, exposed weathering steel exoskeleton frame.

The building was designed as a speculative office, aspiring to exceed the British Council for Office specification and it was the first office to achieve a BREEAM 2014 rating of ‘Outstanding’.

Similar to the adjacent buildings, Four Pancras Square is an 11-storey commercial block offering Grade A office space with ground floor retail zones.

The steel exoskeleton forms the exterior of the entire building, supporting all of the internal floor slabs along each of the four elevations. The external steelwork and the floors are connected at key strategic locations that allow differential movements between the two to occur.

The main feature of this steelwork is a storey-high Vierendeel truss that encircles the building at first floor level.

“The main function of the steel truss is to create a 27m-long column-free façade along the building’s main entrance elevation, that not only overlooks the public realm but forms an important architectural ‘open letterbox’ between the building and the outdoor area,” explains BAM Design Associate Mike Hayes.

The truss was fabricated by Severfield and then brought to site in 18 sections, including four corner pieces. The truss elements measured up to 17m long with the heaviest weighing 72t.

The judges recognised the strong technical collaboration of the entire team to deliver the architect’s vision of an expressed weathering steel exoskeleton without compromise. This was achieved through creative development of key technical details to address thermal bridging, differential thermal movements, fire performance and weathering. The building’s elevations are a celebration of steel.

SSDA 2018: Belfast Waterfront Conference & Exhibition Centre

The new steel-framed extension to the Belfast Waterfront provides an additional 7,000m² of floor space, which can facilitate up to 5,000 guests.

As the SSDA awards celebrate their 50th year of recognising the best of what the UK steel construction industry can achieve, we celebrate that 77% of the projects feature STRUMIS customers. In this post we will be celebrating Walter Watson Ltd.’s involvement in Belfast Waterfront Conference & Exhibition Centre project.

Main Contractor: McLaughlin & Harvey Ltd

Client: Belfast City Council

Flexibility is at the heart of the design for Belfast Waterfront extension as it includes a 1,800m² main hall, together with a 700m² minor hall, both of which can be sub-divided to allow more flexible layouts.

These large clear span spaces were most cost-effectively achieved through the use of a steel frame, particularly given the site constraints.

The conference halls and breakout rooms are also flexible spaces allowing the client to offer tailored events and compete with other UK cities for major conferences and exhibitions. The new banqueting facilities can accommodate 1,000 people making the venue one of the biggest in Northern Ireland.

The use of steel meant the construction works could be accelerated given the opportunity to pre-fabricate the frame offsite in advance.

“Steel allowed the designers to achieve the clear spans and complex layout required for this building to achieve its purpose,” says Walter Watson General Manager Structural Division Trevor Irvine.

Summing up, the judges say new conference halls, banqueting and break-out spaces extend the Belfast Waterfront Conference Centre right up to the quay of the River Lagan. The resulting multiple challenges, both physical and financial, were met by a sequence of appropriate and pragmatic structural steel and architectural solutions.

SSDA 2018: Approach Viaduct South, Queensferry Crossing

Opened in August 2017, Transport Scotland’s Queensferry Crossing is both the UK’s tallest bridge and the world’s longest three-tower, cable-stayed bridge.

As the SSDA awards celebrate their 50th year of recognising the best of what the UK steel construction industry can achieve, we celebrate that 77% of the projects feature STRUMIS customers. In this post we will be celebrating Cleveland Bridge UK Ltd.’s involvement in the Queensferry Crossing project.

Approach Viaduct South, Queensferry Crossing

Structural Engineer: Ramboll

Steelwork Contractors: Cleveland Bridge UK Ltd

Main Contractor: Forth Crossing Bridge Constructors

Client: Transport Scotland

Linking Edinburgh with Fife, the new Crossing stands proud in a unique bridgescape, alongside its illustrious neighbours, the Forth Bridge and Forth Road Bridge (FRB).

The bridge is strategically vital to Scotland. It was commissioned following revelations of potential structural compromises to the aging FRB, which were uneconomical to repair. The FRB was susceptible to weather-related closures, with a huge impact across the region.

On the south side of the crossing the approach viaduct is 545m long, consisting of twin parallel continuous composite decks with steel box sections, supported on six V-shaped piers.

The approach viaduct comprises two composite steel box girders, set 21.75m apart. These are directly connected to the main span cable-stayed single box section of the Crossing.

Steel offered the strength, lightness, versatility, durability and speed, making it an environmentally sustainable solution. Its lightness allowed a delivery solution that minimised any damaging impact on the estuary banks.

“With steep terrain making way for mud flats and shallow water on the south approach, a launched steel viaduct solution offered a number of environmental benefits, allowing us to minimise reliance on marine plant and negate the need for dredging or temporary causeways that would harm the environment,” explains Ramboll Director Steve Thompson.

The viaduct was pre-assembled before being progressively launched into place, following the design philosophy for the entire Crossing; completing complex assembly offsite. Assembly took place in an efficient and controlled environment, keeping work out on the estuary to a minimum.

The steel twin box girders of the viaduct were fabricated and pre-assembled by Cleveland Bridge. The completed girders were transported by road in halves due to the width of the boxes.

SSDA 2018: V&A’s Exhibition Road Quarter, London

The most significant work undertaken at the V&A museum for over 100 years, this development’s centrepiece provides a large column-free underground exhibition gallery.

As the SSDA awards celebrate their 50th year of recognising the best of what the UK steel construction industry can achieve, we celebrate that 77% of the projects feature STRUMIS customers. In this post we will be celebrating Bourne Steel Ltd.’s involvement in the V&A’s Exhibition Road Quarter project.

V&A’s Exhibition Road Quarter, London

Architect: AL_A

Structural Engineer: Arup

Steelwork Contractors: Bourne Steel Ltd

Main Contractor: Wates Construction

Client: Trustees of the V&A

This development at the V&A’s South Kensington campus provides not just a large column-free underground exhibition gallery with an oculus to allow the influx of natural daylight, but also an open courtyard and a significantly improved street level entrance from Exhibition Road into the museum.

Known as the Sainsbury Gallery, the new 1,100m² column-free space is one of the largest temporary exhibition spaces in the UK and allows the V&A to significantly improve the way it designs and presents its world-class exhibition programme.

Following an international competition, AL_A, working with Arup, were appointed as the designers of this scheme. Key to their success in the competition was the use of structural steelwork for the concept design of the folded plate roof. This consists of a system of 13 triangular secondary steel trusses, which span from one large 45m-long primary truss across the gallery, supporting the courtyard, cafe, and crucially allowing the changes of existing ground levels to be fully exploited to fit in a mezzanine floor.

Early engagement by Arup with steelwork contractor Bourne Steel during the design process meant that the design moved from one needing extensive temporary support, to one where the trusses were self-stable, making the erection process much easier.

“Steel was the obvious choice for this development as it could easily form the shape the client demanded,” says Bourne Steel Project Manager Craig Galway. “In addition, it allowed the long spans to be created, while prefabrication of many elements minimised our on-site programme.”

Bourne Steel was responsible for the connection design, fabrication and erection of the steelwork, including the 13 triangular trusses, which each measure up to 25m in length and weighing up to 14t.

SSDA 2018: The Ordsall Chord Viaduct

The Ordsall Chord Viaduct includes the first network arch bridge to be built in the UK, and the first asymmetric (tapering) network arch anywhere in the world.

As the SSDA awards celebrate their 50th year of recognising the best of what the UK steel construction industry can achieve, we celebrate that 77% of the projects feature STRUMIS customers. In this post we will be celebrating Severfield’s involvement in the The Ordsall Chord Viaduct project.

The Ordsall Chord Viaduct

Architect: BDP

Structural Engineers: AECOM Mott MacDonald JV

Specialist Designer: Knight Architects

Steelwork Contractors: Severfield

Main Contractor: Skanska BAM JV

Client: Network Rail

The Ordsall Chord Viaduct is the iconic centrepiece of the new elevated railway that connects Manchester’s three main railway stations for the first time.

It carries a new two-track railway across both the River Irwell and Trinity Way dual carriageway. It sits next to major heritage structures, part of the historic 1830 Liverpool to Manchester Railway, the world’s first inter-city railway.

The context required a design which was of the highest architectural quality, with a structure which would act as a landmark without dominating surrounding buildings.

An 89m span network arch structure was chosen for the main river span, combining great strength and stiffness with a relatively low profile. A 100m long twin girder bridge was selected for the spans over the roadway.

All parts of the viaduct are integrated visually to appear like a single ribbon of weathering steel, tapering at both ends, and sized to suit the specific structural requirements on the individual spans.

“From the early stages of design, weathering steel was considered to be the ideal surface finish for the structures. It provides an honest expression of the material in terms of its function, colour and texture, echoing the historic masonry that sits alongside,” explains BDP Architect Director Peter Jenkins.

The preliminary design concept illustrated box girder structures throughout the length of the viaduct. The design was modified during the design-and-build phase, adopting box girders for the arch ribs but stiffened plate I-girders for the spans over the highway. This reduced construction cost and simplified future maintenance requirements.

Steel was the most cost-effective solution to satisfy the client’s structural performance requirements and also the desire for an elegant, iconic structure. Steel was ideal for the offsite manufacture of a highly geometrically complex structure, and allowed an efficient construction methodology to be developed.
