Sustainable Contractor of the Year: Finalists

Our six Sustainable Contractor finalists have all shown a strong commitment to green building in all its forms, both on projects and within their own businesses.

CN Awards 2017 Sustainable Contractor Canary Wharf Contractors

CN Awards 2017 Sustainable Contractor Canary Wharf Contractors

Canary Wharf Contractors

Last year saw Canary Wharf Group achieve its first BREEAM Outstanding certification for One and Five Bank Street, the largest building in Europe to achieve the rating.

The building was designed to be adaptable and resilient to climate change, with more than 1,500 sq m of green infrastructure included to enhance the aquatic habitats of the docks being developed. The firm published its sustainable design and construction strategy in 2016, which set out 17 ambitious targets across six priority areas, including a commitment to achieve zero waste to landfill on all projects by 2020.

Laing O’Rourke

Laing O’Rourke’s approach to using Design for Manufacture and Assembly ensures that much of its building products have lower embodied carbon – its precast columns contain 39 per cent less reinforcing steel than in-situ alternatives, for example.

The company has also pioneered the use of cement-free concrete in partnership with David Ball Group and Hanson, and the structural use of this ultra-low-carbon concrete will be an industry first. And, since the contractor’s main factory opened in 2009/10, construction waste per unit has reduced by 26 per cent.

CN Awards 2017 Sustainable Contractor Lendlease

CN Awards 2017 Sustainable Contractor Lendlease


There are 19 global projects in the C40 Cities Climate Leadership Group’s programme to reduce greenhouse gas emissions in cities – and three of them are Lendlease developments.

One of them, Elephant Park, is in the UK. A £2.3bn regeneration project, it aims to be ‘climate-positive’ by 2020, helping to tackle issues including air pollution and carbon emissions.

The contractor’s three 2020 targets comprise a 20 per cent reduction in the emissions intensity of its operations, a 20 per cent cut in waste to landfill and a 20 per cent reduction in the potable water intensity of its operations – goals that are being worked towards through innovation and company-wide commitment.

CN Awards 2017 Sustainable Contractor Mace

CN Awards 2017 Sustainable Contractor Mace


Mace trained more than 1,000 people in sustainability in 2016 and developed new courses on tackling modern slavery and responsible sourcing.

The company’s sustainability values were demonstrated in its delivery of Sky Campus projects in 2016: the Believe in Better building, the Health and Wellbeing Centre and a new headquarters.

Achievements included 100 per cent of timber sustainably certified, 98.1 per cent of other key materials certified as responsibly sourced and more than 2,000 tonnes of carbon sequestered thanks to the use of cross-laminated timber, going beyond zero carbon and exceeding Sky’s embodied energy target by 14 per cent.

McNicholas Construction Services

McNicholas’ ‘Our World’ strategy has seen the company achieve impressive results.

An example of this was the firm’s work on a contract with Network Rail in Brighton, for which the business was asked to think of ways to contribute to the sustainability agenda in the local area.

Working with Groundwork UK, which needed assistance sourcing abandoned bikes for its Changing Gears shop, the contractor approached Brighton station to make use of bikes abandoned there and save them from landfill.

Environmentally, the company’s 86 per cent waste diversion rate is having a positive impact, while performance is continually captured and measured via KPIs.

Sir Robert McAlpine

Sir Robert McAlpine will celebrate its 150th anniversary in 2019, prompting the business to set out a 2019 sustainability strategy.

The goals include ensuring that 100 per cent of non-hazardous construction waste is diverted from landfill, that carbon is reduced by 25 per cent and water by 15 per cent, and that 40 per cent of each project’s spend is local.

As part of this, the firm established a sustainability leadership group in 2016 within the business to lead the agenda and ensure it is embedded at all levels.

The company’s work at City of Glasgow College was a particular highlight (see the Sustainable Project of the Year shortlist for more).
