attractive rhythm for the spans of the deck girder. This transparency is accentuated by the slenderness of the thin inclined props, which is achieved by the use of meticulously detailed concrete hinges. The two end props, which spring from the ends of the arch, imposing both physical and visual weight at these points to good eff ect, work as part of an integral framing system with the slightly deeper end spans of the girder. These spans can therefore be longer, avoiding the need for additional foundations at the sensitive upper slopes of the valley. So, the bridge stands on just four foundations, reducing construction uncertainty and maximising the economy of the scheme.

PROJECT TEAM Queensferry Client: Transport Scotland Crossing Forth Crossing Bridge Constructors JV: Hochtief, Dragados, American Bridge International and Morrison Construction Forth Crossing Design JV: Ramboll, Leonhardt, Andrä und Partner, and Sweco

JUDGES’ COMMENTS This is an extraordinary bridge by almost any measure. The scale of the structure is in itself impressive, but what sets it apart from other major long-span bridges in the opinion of the judges is the unique way in which the engineers have dealt with the particular problem of unbalanced loads on a three-tower cable-stayed bridge. The crossing stays at the centre of the two main spans are a unique feature of this design, and by this simple expedient the designers have managed to maximise the slenderness of the elements and achieve substantial savings in the costs of the foundations and the superstructure.

JUDGES’ COMMENTS The Perry Bridge is a very important part of the new footpath and cycleway which runs 70km from Ngaruawahia to Karapiro. The bridge, which spans 130m over the Waikato River, was seen as a crucial element in attracting public interest and support for the path.

“WHAT MAKES THIS BRIDGE SO SPECIAL IS NOT JUST THE ELEGANCE OF THE NETWORK ARCH DESIGN NOR THE EXTREME ECONOMY OF MATERIAL, BUT THE ENORMOUSLY INGENIOUS METHOD OF LAUNCHING”

This beautiful arched bridge has captured the public imagination and its image and the elegance of the design has helped signifi cantly in the fundraising for the project. The slim tubular arches are connected by steel channels to form an in-plane Vierendeel truss providing lateral bracing to the tubes. The network of hangers connects the arch to the bridge deck, which is formed of precast panels post- tensioned together with in situ concrete. What makes this bridge so special is not just the elegance of the network arch design nor the extreme economy of material, but the enormously ingenious method of launching by dragging it over the river, supported on skids sliding on tensioned cables. This was a really clever idea, and a very economical one, and is believed to be the fi rst time that this has been tried with this form of structure. The bridge was pulled across in just two hours by a simple tracked excavator. The enthusiastic reception of the Close-up of completed bridge public to the fi nished bridge is the icing on the cake.

Curved glulam beams and restored cast iron columns

posts which support the primary 600mm deep European whitewood glulam timber beams. These primary beams were curved in the factory to form the pavilion’s distinctive and highly aesthetic roof profi le. The attention to detail, such as in the tapered beams above the outside seating area, which align to the internal moment envelope as well as reducing the perceived depth of the roof at the line of sight, contributes to the elegance of the overall design solution. The structural solutions in this building also implement sustainable techniques and technologies, as demonstrated by the specifi cation of materials, including spruce CLT fl oor panels and ceiling units spanning between the beams. The prefabricated nature of the system aligns to minimising construction waste and the recycling and reuse of the cast iron gives further carbon reductions compared to new build. Another added value is rehabilitating the UK’s oldest velodrome, the home of track cycling in London for over 120 years and the only remaining venue still in operation from the 1948 Olympic Games. It is a tribute to our structural engineering heritage.

EThe Grade 2* listed building required careful and considered design in its conversion from an offi ce to 66 homes complementing the historic fabric and utilising the existing structure to ensure the continued legacy of this important building. EThe key to converting the building to residential accommodation was adding additional levels between the existing fl oor slabs.

PROJECT TEAM Expressed Client: Victoria and Albert Museum steel framing is brightly painted Principal contractor: Wates Construction to celebrate role Architect: AL_A of engineer Steelwork subcontractor: Bourne Group Groundworks and concrete subcontractor: Toureen Group

IN BRIEF… EThe V&A Exhibition Road Quarter delivers a new 1100m2 column-free subterranean gallery for the Victoria and Albert Museum’s temporary exhibitions programme, a new entrance, courtyard, cafe and shop, together with support spaces, storage and plant rooms. EThe gallery is contained in a 15m deep basement, constructed within a courtyard bounded on all sides by Grade I and Grade II* listed museum buildings. The basement extends under one of these buildings to link the new spaces with the wider museum. EThe folded plate roof and courtyard structure spans more than 36m, props the top of the retaining walls and incorporates a mezzanine structure. EThe perimeter basement wall is made up of 470 interlocking bored piles, of which half are 600mm diameter and half are 880mm diameter. ESophisticated 3D analysis, digital design and optimisation methods, together with early considerations of buildability and construction sequence, were crucial to developing the most effi cient and appropriate design, and reducing the risks during construction of this ambitious project. E99.02% of all non-hazardous construction waste was diverted from landfi ll, and either reused, recycled or recovered; contributing to the project’s BREEAM Excellent rating.
