100 Liverpool Street certified BREEAM 'Outstanding'

Sir Robert McAlpine delivers British Land’s first ‘Outstanding’ BREEAM score with 100 Liverpool Street.

Congratulations to our project team at 100 Liverpool Street, whose commitment to sustainability has earned the building an ‘Outstanding’ BREEAM score, with a final post-construction certification of 89.2%.

We were contractually obliged to hit a minimum standard of ‘Excellent’, which was met during the design stage (84.7%). To exceed and raise this standard showcases the capabilities of the team and their desire to constantly drive for the highest standards of excellence across all facets of construction.

Included in our score, was a 100% in both the Transport and Water Categories, and a 94% score in Management. This rating demonstrates that even on a logistically and technically complex project like 100 Liverpool Street, a BREEAM score of Outstanding sits well within our team’s delivery capabilities.

To gain an Outstanding BREEAM rating, the 100 Liverpool Street project team fully embraced sustainability and embedded it into the earliest concept design stage and continued as a key driver throughout the detailed design and construction stages.

This is a significant achievement, being the first British Land’s building to achieve ‘Outstanding’, propelling 100 Liverpool Street into the top 1% of sustainable office buildings in the UK.

Our client British Land’s commitment to sustainability also meant that from the outset, a high bar was set and embedded into the early contractual obligations. Our project team had to constantly monitor and work with all parties involved to ensure that these standards were understood and implemented. Monthly sessions, to assess and collect evidence, allowed for consistent and timely submittals to the BREEAM assessor. The team remained proactive by finding opportunities to gain additional credits by frequently reviewing value engineering exercises in the construction process.

Additionally, the BREEAM evidence collected formed part of a WELL Health & Wellbeing certification, which, on its impending completion, will make 100 Liverpool Street Sir Robert McAlpine’s first WELL certified project.

BREEAM (Building Research Establishment’s Environmental Assessment Method) is the world’s leading sustainability assessment method for masterplanning projects, infrastructure and buildings. It recognises and reflects the value in higher performing assets across the built environment lifecycle, from new construction to in-use and refurbishment.
