Infrastructure and Aviation Business Unit (IABU) - submitted by Mace

Mace was appointed by Heathrow for the first time back in 1992. Their 27-year history with Heathrow is marked by industry firsts and milestones, leadership in engineering and delivery, with notable safety records and sustainability innovations.

There are two forces driving Mace’s progress on sustainability at Heathrow. One is their client Heathrow's 2.0 Plan for Sustainable Growth. The other is their Mace 2022 Responsible Business Strategy. Both were launched in 2017 and aim to lead the way towards a better future.

Mace is one of four integrated delivery partners at Heathrow delivering the Q6+1 phase projects. Their client expects a high level of collaboration between the four delivery partners. Airports are complex environments to carry out construction activities with challenges around security, health and safety and the need to carry out work in a way that allows the airport to be continuously in operation. 

Sustainability

Mace aims to lead on sustainability, both as a business and as a project at Heathrow. Mace became the first UK construction company to sign up to RE100. Their commitment is that by 2022, they will source all their power from renewable sources and they are aiming for 75% by 2019.

As part of their 2022 Responsible Business Strategy, one commitment is to reduce the 3,000 tonnes of plastic waste that Mace generates each year. Their 'Time To Act!' campaign, launched in 2018, responds to global concern about single-use plastics and plastic pollution. The desire to take bold action on eliminating plastics filters down to the project teams at Heathrow. On 5 July 2018, a 'Beat Plastic Pollution' event was held at Heathrow, where attendees pledged to minimise their use of plastic products.

Mace is proud of the work they do with the Carbon Trust. They have been working extensively with their client, suppliers and the Carbon Trust to drive carbon emissions down and drive innovations up at the airport. In 2018, Mace achieved the Carbon Trust Supply Chain Standard – Level 3 (two years ahead of schedule). Mace has been working with the Carbon Trust and their own suppliers to achieve the Carbon Trust Supply Chain Standard – Level 2. They have been working collaboratively to identify areas for emissions reductions and to draft baseline calculations. 

Reducing whole life Carbon within construction activities requires smart processes and techniques. This has been the approach undertaken by Mace at Heathrow. Examples include innovative motors used to future proof the Terminal 5 Hold Baggage System and prefabricated solutions in complicated environments at Terminal 3. To address air pollution, they run a number of initiatives at Heathrow:

  • Increasing the number of pallets on trucks
  • Reducing delivery days from 28 to 10 days a month
  • Working to share stock between the construction partners
  • Encouraging their supply chain to avoid idling when delivering goods
  • 2/3 of the vehicles Mace operate at Heathrow are green and this will be 100% by the end of 2019
  • Aim to use local suppliers as much as possible
  • Plan to design out waste
  • Use extensive prefabrication methods to consolidate deliveries
  • Use of solar lighting tower and an electric screed pump. These proved to be more than equal substitutes for their diesel counterparts. 

Mace aims to make the business of sustainability everybody’s business. To achieve this, they have a number of training programs for staff. The attendance rates for these have been successful, for example, Sustainability 101 was 88% and Sustainable Construction was 94%.

Ethical sourcing is an integral part of what they do and Mace ensures that products and materials purchased on behalf of their clients are produced in conditions that are legal, safe and without impact on the environment.  Additionally, Mace has joined Supply Chain Sustainability and they encourage Mace supply chain partners to engage and use the resources available to them as members. In the space of six months, Mace achieved the Bronze and Silver ratings and progressed to attaining Gold in November 2018.


Highlights:

  • The electric screed pump used at Heathrow was the first in the UK and was brought from Switzerland as a trial.
  • Mace was the first construction company to sign up to RE100.
  • The Mace Infrastructure and Aviation Business Unit have shown leadership in the field of sustainability.
