Farringdon Station

London

Passengers at the new Farringdon Crossrail station will be greeted by a sequence of stunning concrete ceilings, writes Tony Whitehead.

HMP Five Wells

Wellingborough

The design team optimised the DfMA component library by reducing the number of precast concrete components by almost 50%, providing a programme saving of 18.5 crane weeks per houseblock.

Kingston Townhouse

Kingston University

The new Town House at London’s Kingston University is a mixed-use building that has in recent years become increasingly popular with academic institutions.

One Station Square

Cambridge

One Station Square, a six-storey BREEAM ‘Excellent’ mixed-use building utilised a precast concrete facade. The facade’s design was driven by the need to minimise solar gain whilst maintaining excellent levels of beneficial daylight along with a view out.

The Lansdowne

Birmingham

The Lansdowne is a 17-storey residential building in central Birmingham, with a precast structural frame, plus numerous other precast components.

舞台中央

Birmingham

舞台中央is a two block (17 and 22 storeys) residential development in Birmingham. The project utilised precast concrete systems including the building’s structural frame, cladding and balcony units.

Victoria & Albert Museum

Dundee

The UK’s Victoria & Albert Museum stands on the waterfront of Dundee, a city in the north of Scotland. It is the first design museum in Scotland and is expected to function as a base for promoting Scottish culture.

Concrete Compass: Offsite concrete construction

Navigating to useful resources and guidance

The use of precast concrete elements is a well-established construction method. Concrete offsite solutions range from whole building and structural systems, to precast construction components, offering numerous benefits during construction and over the whole life of a building. This compass brings together some of latest information and resources, including guidance documents and case studies, that can assist in making informed design decisions.

Our head of architecture, Elaine Toogood, looks at the full range of offsite concrete construction methods, their advantages and applications, in herblog.

Key guidance

The Concrete Centre has a number of resources that provide comprehensive guidance for designers.

  • Offsite Concrete Constructionis a free-to-download publication which includes guidance and benefits of using offsite concrete construction and delves into details of some of the more common techniques. This 24-page guide is a great starting point for those wanting a comprehensive overview of design considerations.
  • Residential Cellular Concrete Buildingstechnical guide, includes detailed ‘How-To’ guidance on construction systems, including crosswall, tunnelform and twin wall.
  • Concrete Offsite Solutions on-demand webinarThis webinar explains the range of offsite solutions available in concrete and their benefits, along with design guidance for their use.

Focus on...

As featured in Concrete Quarterly magazine and other key journals, here is some useful guidance.

Sustainability

There are many ways in which precast concrete can be used as part of sustainable buildings. In addition, there are many sustainable benefits that are available due to the manufacture and supply chain, including low waste production, lower carbon concrete, responsible sourcing and the use of recycled content.

  • Summary of the sustainability benefits of precast concrete feature in theOffsite Concrete Construction guide, published in 2019.
  • Offsite solutions in concrete are often manufactured to suit project specific criteria, which can include project specific sustainability performance from responsible sourcing, to cutting carbon. For more information seeSpecifying Sustainable Concrete, published in 2020.
  • Generic Environmental Product Declarations (EPDs) have been published by MPA Precast, working closely with sustainability consultants thinkstep. Together they produced a life cycle assessment tool to enable MPA Precast to produce verified EPDs in accordance with BS EN 15804: 2012 +A1 (2013). The tool has an extensive list of over 50 material inputs covering all the commonly used aggregates, cements, reinforcements and admixtures. These third-party verified EPDs can be accessedhere.
  • Easy to use carbon fact sheets for brick-faced and stone cladding and structural precast elements are available to downloadhere. These were produced prior to theEPDs(above) and therefore should only be referred to if needed once the EPDs are consulted.
  • The precast concrete sector reports annually viaSustainability Mattersand the sector is also part of theConcrete Industry Sustainable Construction Strategy, that also reports performance annually. There are also articles inConstruction News supplement显示的进展Precast Sustainability Charter Schemeandcarbon reduction targetsand the sustainability benefits of precast concrete.

Codes and Standards

The structural design of offsite concrete construction is to Eurocode 2 (BS EN 1992-1-1) but there are further codes for precast concrete elements. The general code for all precast concrete elements is BS EN 13369 and a list of codes for specific elements can be foundhere.

UK Precast Concrete

There are a number of specialist groups that represent the UK precast sector:

  • MPA Precastis the trade association for the UK precast concrete sector. As an industry body it operates a number of specialist product groups as well as sector schemes for health and safety, and sustainability. More information about thePrecast Sustainability Charter.
  • MPA预制建筑和结构组provides expertise and experience in offsite construction. Available resources include newsletters on a vast range of construction sectors and precast concrete applications, including cladding and its use of digitalisation, such as BIM. Read more via the出版物图书馆。
