NSC March 2009 15 Transport Portal frames on track Steelwork design has played an important role in the construction of a traincare maintenance depot for east London’s new overground railway line.

The East London line extension and upgrade forms an important cornerstone of Transport for London’s (TfL) £10bn investment programme and will also play a major role transporting people to and from the 2012 Olympic Games. The former underground line will become part of the capital’s overground rail system and it is being extended north from Shoreditch to Highbury & Islington as well as south from New Cross to Crystal Palace and West Croydon. The new line is scheduled to open in its entirety in May 2011. As part of the overall £363m rail contract awarded to the Balfour Beatty Carillion joint venture, a new traincare maintenance depot is being constructed at New Cross. The project involves the construction of two main steel-framed buildings, along with a group of ancilliary structures. The largest structure measuring 105m long with 37m spans and a 10m clearance, known as the Maintenance Facility Building (MFB), consists of a maintenance hall with Above: The MFB under construction. inspection pits and a bogie jack road, associated stores and workshops served by gantry cranes, plus Right: The completed MFB. 4,500m2 of associated depot management offices and welfare rooms.

This structure contains steel member an upper level of staff accommodation, a control size available.” room, offices and locker room/welfare and messing facilities. A further, 40m long x 7.5m wide, steel portal framed building houses a drive through carriage wash. Requiring approximately 35t of steel, this is the largest of several ancilliary buildings erected during the project. For the MFB, in particular, there was a design requirement for a large column free area and consequently the structure has been built as a portal frame shed to span four incoming rail lines. Three of these rail tracks have maintenance inspection pits beneath them.

The WLHC building contains two halls, one for maintenance and one for jet washing of trains.

Grenville Griffiths. “As well as the long spans the MFB steel frame also incorporates four 2.5t capacity overhead runway beams which run the full length of the building.” The steelwork programme was spread over a year to allow coordination and sequencing with other trades, Caunton made a number of return visits. One of these was to erect the MFB’s way beams and internal gantries. The site was very confined with plenty of other construction activities taking place simultaneously, so with space at a premium, Caunton erected most of the steelwork with one 50t capacity crane. This worked well,” says Mr Griffiths. “But we did have to use an 80-tonner to land the concrete planks for the three-storey office.” Coordinating and checking the steelwork design, Tony Gee & Partners (TGP), also designed the MFB and WLHC building substructures. TGP Project Engineer, Martin Allnutt, says both buildings are founded on piled foundations due to the existing made ground and tight tolerances on differential and total settlement. “The heavy train lifting jacks in the MFB and the wheel lathe in the WLHC building are both very sensitive to vertical deflection of the substructure.” As well as spanning the works area, the Meanwhile, the steel superstructure also had to FACT FILE East London Line train overhead steelwork also had to be rigid enough to be rigid enough to support the MFB’s hoists and its maintenance depot, support a series of gantry cranes.

The BCSA and Corus have announced a major initiative to help make zero carbon buildings a reality. The £1M ‘Target Zero’ project will provide designers with the guidance they need to meet emissions reduction targets towards the aspiration of zero carbon by 2019. The construction industry faces an unprecedented challenge to significantly reduce the greenhouse emissions from the built environment. Because there is a lack of reliable data to inform those that make technical decisions, the BCSA and Corus have resolved to fill this gap by commissioning sustainability specialists Faber Maunsell / AECOM, assisted by cost consultant Cyril Sweett, to deliver ‘Target Zero’. The aim of the project is to understand the implications of the UK Government’s move towards zero carbon for construction of non-domestic buildings. ‘Target Zero’ will research and cost options for improving operational energy consumption and reducing embodied energy. Over three years ‘Target Zero’ will look at five major building types (schools, warehouses, offices, supermarkets and mixed-use) and will generate fully- costed solutions The demonstrating Target Zero delivery how to partners are: achieve the Corus – Europe’s second largest steel three highest producer, a subsidiary of Tata Steel; BREEAM BCSA – The national organisation for the steel construction industry, particularly steelwork contractors; SCI – A consultancy based steel research and dissemination specialist; Faber Maunsell / AECOM – A multi disciplinary consultancy specialising in the planning, design and engineering of buildings, transport systems and environmental services; Cyril Sweett – a leading international construction and property consultancy offering expertise in cost consultancy.

ratings and meet the anticipated changes to Part L of the Building Regulations. Guidance will be produced for each of the building types with the first reports due to appear later this summer. A new report will appear approximately every three months until all building types have been covered. BCSA President Richard Barrett says: “The schools study has already identified potential annual energy savings of £165M nationally, equivalent to £22 per pupil. The steel sector has a long history of providing the guidance designers need to make the best use of steel. The latest information they require relates to sustainability and the reduction of carbon in buildings. Target Zero is a focussed practical study to deliver that information.” Corus has developed a new methodology for calculating the embodied energy for steel sections which takes account of the multi-cycling nature of steel. Figures for the tonnes of CO2 /tonne of steel have been calculated for steel sections and plate. Alan Todd, General Manager of Corus Construction Services and Development comments: “There are many highly sustainable steel-framed buildings and many have achieved the highest ratings under BREEAM. Steel itself has many advantages and a steel-frame is a great enabler of sustainability in a wider sense. The ‘Target Zero’ project will provide useful guidance for the increasing number of designers who have an interest in achieving best sustainable performance.”

NSC March 2009 23 The Case for Steel Steel makes sound economics case

The latest in our Case for Steel series highlights the many cost advantages associated with steel construction.

The strong financial case for using steel is often the deciding factor for cost conscious developers. As well as a highly competitive up front initial cost, Foundations steel has many other cost advantages that pay-back during the course of construction and throughout the building’s working life – even when a steel framed building or steel bridge reaches the end of its useful life it generates a cash value through recycling, as virtually all structural steel is certain to be. Other cost benefits derive from factors such as the speed of construction made possible by off site fabrication and offsite application of intumescent and other protective coatings. Steel doesn’t have to be stored on or near to sites and it will be delivered only when the construction programme demands it, saving on expensive storage space. On site waste Independent studies just doesn’t happen with steel – only over the past 20 years what is needed and more have is produced, to the most exacting consistently shown tolerances, and delivered to site steel providing the where it is speedily most economic erected by skilled teams. solution in most cases. The cost of Cost savings in steel buildings start at the foundations, where the loads constructional steelwork has fallen significantly imposed by a steel frame are up to 50% less than those of a concrete in real terms over the past 20 years thanks to alternative. That means foundations can be much smaller and therefore massive productivity improvements made by cost considerably less. Foundations are a major component of overall Corus, steelwork contractors, intumescent paint building costs, so lighter foundation loads can have a big impact on manufacturers and others in the supply chain. costs. Sharing the benefits of these productivity gains with clients has helped keep the real terms price of steel below alternatives. Independent studies carried out over the past 20 years and more have consistently shown steel Durability providing the most economic solution in most cases, whether for one of the new breed of highly sustainable sheds or for a multi storey corporate headquarters. Cost Comparison studies consistently show steel to be the more cost effective choice for buildings. The market obviously appreciates this as the most recent Market Shares survey, for 2008, shows steel now commands over 70% of the market for multi storey buildings, and a non steel single storey building is hard to find – over 90% are made with steel. Value engineering usually results in steel being chosen in preference to any concrete alternatives that might have been considered.

24 NSC March 2009 The Case for Steel

In inflation-adjusted terms steel has fallen in price since 1980 and is cheaper than it was 15 years ago. One of the best guarantees of a competitive price is the large number of steelwork contractors that can tender for projects. A competitive sector ensures that customers get value for money - there are some 150 audited steelwork contractor members of the British Constructional Steelwork Association (BCSA).

Cost savings in a competitive market

Steel structures can be erected speedily, delivering time savings in the build programme compared to a concrete frame. In fact, speed of erection is often one of the main criteria for selecting steel. The predictability and accuracy of steel components speeds up the process and allows follow-on trades to get to work sooner. A faster build means a faster return on investment through sale or rental income, or productive use Speed of the building.

Product confidence for the steel sector

Andrew Way from SCI explains the advantages of the range of assessment services offered by SCI for steel sector construction products and building systems.

The number of available construction products and building systems for use in the steel construction sector is continually increasing. New products and systems are growing in complexity and are invariably pre-engineered for optimised performance across a range of criteria which relate to both structural and non-structural requirements. Manufacturers and suppliers provide information declaring performance values and capabilities for their products. However, clients and specifiers must have confidence in the products and systems and the information which is provided by their manufacturers and suppliers. This is where third party assessment and certification can be extremely beneficial. Product manufacturers and system suppliers come to SCI for assessment of their products and the performance of their systems because SCI’s brand, independence and expertise place SCI in Purlin from Duggan Profiles & Steel Service Centre being tested at CERAM. The test results a unique position to offer technical assessment are used by SCI to produce SCI Assessed load span tables for the range of purlins. services to the sector.

Designed for Colour Transmission Yorkshire Television Studios

Yorkshire Television Ltd began a race against time in the middle of 1967, for on 12th June the company was allotted the new ITV broadcasting contract for the completely new Yorkshire TV region: and transmission were due to begin in July 1968. The company was thus faced with the task of designing and constructing a major new studio complex within this extremely short period. The architects were commissioned to prepare a feasibility study as part of the company’s proposals submitted to the ITA. Their proposals were for a major TV centre costing £1.5M, on a site made available by the City Corporation at Leeds, and which was to be completed in two stages. The first stage included all the essential production facilities which the company would need in order to begin broadcasting in July this year, further studios and administrative offices to be completed as soon as possible thereafter. The architects built up and co-ordinated a full project ream which was prepared to go ahead at high speed with design and construction as soon as the ITA announced its award. Prior to the Design Team commencing the final design of the building and its structure the general contractor carried out some initial studies for the construction period required for the superstructure in both steel and concrete and, as a result of these investigations, it was concluded that a steel frame would give the shortest construction time. An additional factor was the decision to adopt a steel frame was that in view of the time factor involved, structural design had to proceed concurrently with and at times ahead of general planning and the relative ease Above: Interior of the studio - view from the gallery showing the windows to the control rooms, production lighting grid and the acoustic treatment of the walls. of adaptability of a steel frame was felt to be desirable. Below: Steelwork under construction. The main requirements of Phase I construction consisted of two studios measuring 80ft by 64ft and 40ft by 40ft respectively with three storey ancillary accommodation housing technical areas, control rooms, ventilation plant, etc. and single storey cafeteria, kitchen and workshop space. For acoustic reasons the structures of the two studios are entirely independent of the surrounding three storey structure. The frame of the larger of the two studios included in the first phase is constructed with 60ft span lattice trusses supported on steel stanchions. Final stability of this studio structure, which, of course, derives no support from the surrounding structure is provided by 9in thick infill panels of brickwork necessary for acoustic reasons but temporary vertical bracing was used to provide initial stability until sufficient brickwork had been constructed.

Concrete encasure of the steelwork was confined to the stanchions and perimeter wall beams, the necessary two hour fire protection being provided elsewhere by 2009 the use of vermiculite panel cladding. Final design of the structure was begun towards the end of June 1967 and the steelwork sub-contractor commenced work during the last week in August 1967 and completed in November 1967 within days of the programme target. During this comparatively short period the steelwork sub-contractor had erected some 450 tons of steelwork and carried out numerous detailed revisions to the structure which had become necessary as final planning proceeded. Sections of the building were completed and handed over the clients to begin technical installation progressively from 5th March 1968.
