Resource efficiency

BAM has a long term ambition to become Net Positive. In order to achieve this we are planning our journey towards zero construction waste. This includes using BIM to build buildings twice, engaging our supply chain to take steps towards creating a circular economy, and pushing boundaries with prefabrication such as the Neasden Primary School


Towards zero construction waste

Continual waste reduction

We work hard to reduce the production of waste at source. That is why we engage the whole supply chain, from designers through to subcontractors and materials suppliers, to understand how better design, improved packaging and the more efficient control of materials on site can contribute to waste reduction. We continue to hold design for resource efficiency workshops in order to work with clients and design teams at the earliest stage possible on projects, as a project's design can have a large influence on the waste produced on-site.




We work to understand how design influences on-site waste








Although there is a priority to prevent waste in the first place, we continue to track the quantity of waste removed from sites with a target for reuse, recycling or as a last resort, recovery and landfill. This is normally by using specialist waste transfer stations that achieve the highest possible value from the waste materials taken from our sites. There are also a growing number of suppliers offering takeback schemes for their materials, which will be used as the feedstock for the production of new product.






 

To align with new targets across the Royal BAM Group, BAM Construct UK is beginning to record the tonnes of waste removed from our sites (we previously reported in m3), making use of more primary data from our waste management contractors. We have also set a new target against a new 2015 baseline. In 2015 the three year rolling average has been calculated as 40 tonnes/£1million turnover. The three year rolling average for 2016 was 37.5 tonnes /£1million turnover, a 7% reduction. This is a good start to the 25% reduction that has been targeted by 2020. BAM Construct UK continues to pursue our target to achieve zero non-hazardous waste to landfill. The proportion of waste diverted away from landfill currently stands at 93%.

Towards resource positive

Our focus has previously been on reduction, however our aim is not to just do things better, but to do new things. That is why we continue to use our position as an industry leader to share our experiences and drive the performance of the construction industry by working with the UK Building Council, Supply Chain Sustainability School and Build UK. And we are working with clients, suppliers and peers to facilitate the step change we need to do things differently, for instance we are one of 16 partners working on the 'Buildings as Material Banks' EU Horizon 2020 project, which hopes to catalyse a move to circular buildings.







 

We also recognise the whole lifecycle impact of buildings is where we need to focus in the future. In 2016 we continued to get to grips with the circular economy, taking part in a range of projects. We worked on BAMB (Building as Material Banks), a Horizon 2020 project aimed at helping the industry to better understand the design and business model solutions to reducing waste and increasing the value of buildings. During 2016 this project focussed on building a wide network of industry stakeholders to engage on early outputs, including design protocols for reversible design, and digital tools to track the value of materials within a building over its life.

BAM Construct UK also held a series of circular economy workshops for members of our supply chain, was involved in designing and building a circular pavilion in London, and worked with Arup to produce a document exploring the benefits that circular business models offer stakeholders within the built environment.
