The redevelopment of Broadgate, London

We are working with British Land and GIC on Broadgate’s evolution into a world-class retail, leisure, and commercial destination, bringing people together to work, shop, drink and dine.

The ten-year redevelopment of Broadgate is transforming central London’s largest pedestrianised neighbourhood into a world-class, mixed-use destination.

To realise their vision, British Land wanted a main contractor who could not only deliver, but who would help them make the most of opportunities for collaboration, early contractor involvement, community engagement and commercial savings.

As sole contractor on the 10-year Broadgate Framework, stakeholder and community engagement is key to the long-term success of the project. We’re keeping local transport providers, businesses and professionals updated through well-planned communications and creative technology.

We’re committed to sustainable construction practices at Broadgate. We’re monitoring and managing emissions and ensuring a legacy in the community by providing skills and opportunities for local communities where possible.

On completion, 100 Liverpool Street became British Lands first net zero carbon building, in addition to being awarded BREEAM Outstanding. This set the tone for British Lands journey to Net Zero by 2030, demonstrating the capability of Sir Robert McAlpine to deliver to such high standards. 100 Liverpool Street has been submitted for a WELL accreditation, pending Gold Level status on verification.

The Broadgate Vision

1 Finsbury Avenue

Shared Values

Trust, Honesty and Collaboration: it’s the mantra for all at the Broadgate framework. It’s even printed on our notebooks.

Greening Cities

100 Liverpool’s Street’s landscaped outdoor terraces will provide social areas while attracting more birds, butterflies and bees to Broadgate. It is now British Lands first net zero carbon building.

Celebrating Heritage

The Grade II Listed 1 Finsbury Avenue has been sympathetically restored to retain its original design and features, and is now an award winning building.

Air Freshening

We won an environmental prize for our commitment to monitoring and reducing emissions over the development period.

Long-term legacy

We’re maximise the positive impact of the framework through a 10-year community investment programme.

  • “Sir Robert McAlpine were chosen based on their team, methodology and commercial offer…

    “I can say without hesitation that Sir Robert McAlpine is a long-term partner of British Land on other projects, not just on this one.”

A one team approach to working with our client and supply chain

Our framework and project teams share offices with the client, consultants and subcontractors to make communication and collaboration as easy as possible. This makes sure every project in the 10-year programme achieves high standards. We’re also saving money through economies of scale on non-architectural building features.

The framework means we can share our expertise and learn from experiences through a one-team approach. The entire project benefits from agile collaboration practices and helps us identify ways we can save our client time and money.

We’re saving time and reducing risk by standardising approaches to every project in the framework. It means everyone is clear on their responsibilities.

Sharing our approach to sustainable resourcing, ethical employment and diversity

We work with a trusted network of suppliers who share our values on issues such as apprenticeships, fairness, and respect, and have been briefed on our commitments to sustainable resourcing, ethical employment, and inclusion.

The Broadgate App: A digital solution to Stakeholder Engagement and Community Communications

Thousands of businesses and professionals operate in and around Broadgate every day. Given the 100 Liverpool Street's extent and duration, it was critical to keep our neighbours updated.

To boost stakeholder engagement and community communications, we worked with British Land to create a smartphone app. Using this, tenants, retail leisure and office operators, as well as external stakeholders and members of the general public, could easily:

  • Find out about project plans, milestones and timeframes.
  • See where works are happening on a 3D interactive map,
  • Set up notifications for potential disturbances.
  • Send comments or questions to our team.
  • Keep up to date with events, retail offers, job and training opportunities

Providing work experience opportunities for local students

Working with the University of East London, the Broadgate Prize is an opportunity for degree students to develop their team working skills as they work with British Land and Sir Robert McAlpine on a live project. The prize has a rich history, dating back to 2015. Thus far it has impacted over 250 students across three different courses; BSc Architecture, MA Architecture and BSc Architecture Design Technology. The prize has delivered three built structures and offered 20 students paid work experience over summer vacation with some of the world’s leading design firms.

Previously we organised a competition for local architecture students to design a welfare facility consisting only of materials salvaged from the building at 1 Finsbury Avenue. Then we offered paid work experience opportunities to help create their designs.

The 2020/2021 Broadgate Prize is the design of a roof-top extension at the 6-9 Eldon Street offices in the Broadgate Framework around Liverpool Street Station.

Reducing environmental impact

Reducing the environmental impact of our operations is integral to all we do. That’s why we’ve been monitoring air quality across the estate since the programme began. Addressing this ongoing problem for the City of London has won us awards. We’re encouraging the reduction of pollution in our supply chain by reporting on diesel emissions across all of our subcontracts.

Digital Construction Leading the Way

During the construction of 100 Liverpool Street, we began utilising BIM and digital technologies to coordinate many of the intricacies that the project presented. BIM was not a requirement on the project, but by implementing BIM on all projects this helped to manage parts of the project like the new steel frame, glass atrium and atrium staircase.  BIM was used to map out and coordinate many of the challenging aspects we encountered and ensured the large number of services were accounted for. This proved a pragmatic way to facilitate difficult works and allowed for an array of engineering solutions to be utilised for those challenging elements of the project. As we continue our work on the Broadgate Framework, BIM is now a requirement by British Land for 1 Broadgate and 2 Finsbury Avenue, where digital information will inform their Smart and CAFM systems post practical completion. This supports more efficient ways of delivering information at handover for building operations and strengthens our relationship with British Land.
