Memorandum by Laing O'Rourke

EXECUTIVE SUMMARY

  Laing O'Rourke seeks to challenge and change the image of construction worldwide, part of a vision developed against the background of a very different commercial dynamic—but arguably a vision of even greater relevance now than when first set out more than a decade ago.

  Within our wider vision the Group also seeks to be the company of first choice for all stakeholders and, finally, we say that with leanness and agility we will adopt processes to compete with world-leading businesses.

  In each aspect of this three-pronged vision the focus is on learning, changing and—above all—behaving in a manner which transforms the "attractiveness" of the sector in which we operate. Clearly one of the least attractive aspects of an industry not noted for its environmental management credentials is the reputation attached to it around waste—in all its forms.

  With a Group turnover in the order of £4 billion and worldwide employees of around 30,000 we carry significant responsibilities. As the UK's largest privately-owned construction Group we seek to challenge and change in a number of ways, principally:

    —  the practical application of innovative solutions to complex challenges;

    —  training and developing employees and, above all; and

    —  instilling the culture of everyone returning home safely every day.

  These are the pillars on which our businesses are built and by referencing these in the context of the over-arching vision we meet each challenge. Defining waste consistently and coherently, while creating practical strategies to mitigate waste in all its forms demands responsiveness within an overall framework—and real engagement with the consequences of failing to act on waste at all levels of the business.

  This means ensuring that our people are not operating rules by rote but actively thinking through the waste mitigation opportunities (and risks) presented at each step within a supply chain and site assembly process. Empowerment of the individual comes through shared knowledge and an ingrained understanding of the importance of tackling waste, against the environmental consequences of which we are all too well aware.

  Our approach to this is within the context of the various regulatory and legislative boundaries which govern the industry. While those boundaries are appropriate, we nevertheless seek to work collaboratively with our clients, suppliers and other stakeholders to ensure we pursue ways of going above and beyond regulation.

  This means, for example, going beyond construction to adapt learnings from elsewhere. As a Group we firmly believe that a radical shift away from the traditional labour intense, component heavy onsite environment is not only the way of the past, but the great ally of wastefulness.

  Lean, efficient offsite manufacturing and pre-assembly methods, adopting techniques from industries such as automotive manufacturing, are the way of the future. Fewer people onsite, working with fewer pre-ordered materials in an efficient, clean and effective manner reduces component waste and introduces measurable cost and safety benefits.

  Our commitment to offsite manufacturing is tangible. It can be seen through our investment in the proposed Steetley manufacturing facility on the Nottinghamshire/Derbyshire border which will be the most advanced pre-assembly plant of its kind in Europe. Additionally we are investing heavily in ensuring that the onsite teams employed to assemble finished components are highly skilled, properly rewarded individuals who see themselves as part of high-performing teams moving from project to project.

  While this is the broad aspiration of the Group, our goals will be better met if we can influence policy direction in the development and design of public sector construction whereby the benefits of consistency can be shared. This means the critical examination of whether bespoke designs, often presenting challenging and unique concepts in the public realm, are the most sensible way of minimising waste and maximising shared efficiencies.

  Our goal is to become a Total Solutions Provider for all our clients. This means involvement at the earliest stage of any project through its design and assembly and on into the maintenance and eventual decommissioning phases. The resource benefits that are presented by managing waste at each stage of this process are limitless—and the Laing O'Rourke Group is fully committed to playing its part in meeting that challenge head on.

BACKGROUND

  Laing O'Rourke Group (LO'R) is the largest privately owned construction company in the UK, with offices in Germany, India, Australia and UAE and around 30,000 employees worldwide. We specialise in delivering ambitious construction projects and are responsible for some of the most innovative construction solutions anywhere in the world. However, as a major construction company, we are well aware of the growing pressure to reduce the impact of construction waste upon the environment and further reduce wastage of resources.

  Beyond a growing raft of regulations (such as the implementation of Site Waste Management Plans) and market pressures (such as increasing landfill tax), public and private sector client organisations are increasingly looking to set requirements to reduce waste, recover and recycle more materials. Reducing the amount of waste generated, diverting materials from landfill and reusing recovered materials are genuine cost-neutral and cost-saving incentives to reduce waste.

  Laing O'Rourke's Corporate Responsibility (CR) Strategy (and more specifically, its Environmental Management Objectives) sets targets and strategy for key elements of the sustainable construction agenda. For example, we have a corporate target to reduce waste from our construction sites and in the imminent future we intend to introduce corporate indicators for m3/£100k spend, the percentage of waste we send to landfill, and our total spend on waste.

  To accelerate our waste management agenda from "compliance" to "minimisation" and "resource efficiency", Laing O'Rourke engaged with the Government's Waste & Resources Action Programme (WRAP). WRAP has supported Laing O'Rourke in finalising its revised Site Waste Management Plan (SWMP) template and developing accompanying guidance, which was rolled out to all sites in advance of the introduction of the Site Waste Management Plan Regulations in April 2008. Together with training site staff on how to implement the resulting SWMP, LO'R is committed to integrating waste minimisation, sustainable waste management, and waste data reporting requirements into its procurement procedures. In addition, Laing O'Rourke is looking to increase the use of recycled material in its construction projects by trialling WRAP's Recycled Content Toolkit across LOR's businesses and projects.

  Innovative technological solutions such as design, off-site production, logistics and better site management practices including procurement procedures, are all part of Laing O'Rourke's agenda for improving waste performance. We believe we have put in place a coherent process which fits with our CR strategy, is integrated into core business processes and can deliver significant waste savings in the construction process.

1.  TECHNICAL SOLUTIONS FOR MINIMISING WASTE

Design

  Laing O'Rourke believes substantial savings can be achieved by adopting principles of standardisation in design or by engaging with the supply chain to ensure that standard manufactured components can be adjusted to suit a specific design.

  For example, plasterboard is a product which often attracts a significant amount of waste from over-ordering or from cuts, because the panels do not match the designed dimensions. On the Laing O'Rourke Meath Gardens Project, standard length plasterboards of 2.7 m (instead of 2.4 m) were used as we recognised that there was an opportunity to save money and reduce waste by using boards which matched the floor to ceiling height. Production of waste plasterboard was greatly reduced as all horizontal cuts and joints were virtually eliminated from the dry lining works.

  The water industry is another sector which has adopted innovative solutions to reduce waste through trenchless technology. Through our alliance with Welsh Water, we have rehabilitated approximately 370,000 metres of pipeline during the 2007-08 period with approximately 332,000 metres being undertaken through trenchless technology. We have estimated that this trenchless technology has saved around 295,000 tonnes of waste, all of which could have potentially been sent to landfill.

Material specification

  We believe there are considerable opportunities to minimise waste through product specification, through a "closed loop" or "cradle to cradle" approach, or by using secondary or recycled aggregates which have low environmental impact.

  At Heathrow Terminal 5, Laing O'Rourke and BAA strove to include products with a high recycled content in the construction of buildings and infrastructure. Over 80,000 tonnes of recycled and secondary aggregates were brought onto the project in addition to the crushed aggregates generated on site. This included crushed glass from local municipal recycling banks that was used in the construction of the site roads. Up to 30% of the concrete mix used in the construction of the buildings, taxiways and aircraft stands is pulverised fuel ash (PFA), a waste product from the power generation industry. Using this recycled product and an innovative variable thickness concrete saved over 9,100 tonnes of CO2 emissions.

  In 2000, Laing O'Rourke used recycled aggregates as capping for service access roads and car parks at Glasgow International Airport, with similar practices being adopted at Edinburgh Airport for the construction of a 1,320 space single level car park and a multi-storey short-stay car park directly outside the airport terminal building.

  By January 2004, Laing O'Rourke was responsible for recycling over 33,000 tonnes of aggregates sourced from both off-site and on-site sources and utilised as a sub-base.

EXAMPLE: EDINBURGH AIRPORT MULTI STOREY CAR PARK

    —  Recycled and reused 29,000 tonnes of hard and soft landscaping.

    —  Prevented 1,200 truck movements, saving £72,000.

    —  Using RSA rather than virgin stone, saving £10,000.

    —  Saving £165,000 when comparing recycling costs to landfill.

    —  50% reduction in truck movements.

2.  OFF-SITE MANUFACTURE

  Off-site manufacture can offer significant advantages compared to site assembly since the risks associated with weather, programming, trade co-ordination, on-site plant and equipment and project health & safety are reduced. Laing O'Rourke has embedded off-site manufacturing into its core business strategy which is being demonstrated by our investment in the Steetly Manufacturing centre which is due to come on line in August 2009.

  In addition Laing O'Rourke owns Crown House Technologies (CHt) a subsidiary company which is experienced in the field of off-site manufacturing of mechanical and electrical building components for air-conditioning, heating, cooling, ventilation, electrical services and sprinkler systems. With an in-house manufacturing capability the projects delivered by CHt have led to improvements in quality, reduced labour, reduced material waste, logistics and improved production performance.

  The modular plant rooms arrive on-site ready for installation using a "plug and play" approach. Delivery to site can be on a "just-in-time" basis as the plant room is pre-commissioned and remains sealed until use. The plant rooms are manufactured in CHt's manufacturing facility in Wolverhampton.

  Expanded Big Block, a new specialist division of Expanded Limited (owned by Laing O'Rourke) has started to install a prefabricated large format blockwork system manufactured by Xella (and many other manufacturers). Standard blocks are 1,000mm long and 645mm high and are made from calcium silicate; a substance with much lower environmental impact than concrete as it contains no cement—just lime, sand and water. Big Block construction has many benefits over conventional blockwork including shorter programme, less wastage on site as no cutting of blocks is required, no requirement for scaffolding as all laying can be done from scissor lifts, no manual handling of blocks is required and calcium silicate has high thermal mass.

Logistics

  Consideration of waste during design, construction and even operational phases of Terminal 5 enabled the successful implementation of waste hierarchy. Over 97% of waste material was recycled or recovered. A "just-in-time" logistics strategy adopted at Heathrow Terminal 5 and on-site housekeeping practices such as designated storage areas and segregated vehicle and pedestrian routes ensured that materials were delivered to the work place as they were needed, and not stored on site. This reduced the amount of material damaged on site and therefore reduced waste. Typically on a construction project, this can account for 10% of materials ordered, which then often end up in a skip unused.

  Laing O'Rourke and BAA worked with suppliers to reduce the amount of packaging delivered to the T5 site. To ensure buy in, sustainability workshops were run for suppliers focusing particularly on reducing packaging waste. Other steps were taken to reduce waste from the outset:

    —  All suppliers were encouraged to reduce packaging as far as possible and choose reusable materials to package their products.

    —  Where packaging is unavoidable suppliers were encouraged to take back the packaging they supplied for reuse.

    —  Agreements with the cable suppliers enabled cable drums to be returned to the supplier for reuse.

    —  Standard specifications for products such as paint enabled them to be ordered in large quantities, thus reducing waste and enabling large packaging to be returned eg ICI Dulux paint cans were returned to the supplier.

  On site consolidation of waste using compactors and roll packers, whilst not reducing the weight of waste significantly reduced the volume of waste sent off- site, reducing the number of vehicle movements. Consolidation of hazardous materials during construction significantly reduced the transport of these materials.

3.  SITE PRACTICES TO MINIMISE WASTE

 (a)   Procurement procedures

  Laing O'Rourke's advocacy support from WRAP included the identification of opportunities for waste minimisation and resource efficiency through procurement practices. Laing O'Rourke's Site Waste Management Procedures require subcontractors (by contractual agreement) to provide information on their waste streams and their ideas to reduce waste quantities. Early engagement of the supply chain, together with designers is key to identifying and reducing waste where Laing O'Rourke plays the role of Principal Contractor.

 (b)   Segregation to improve recycling

  Where possible, segregation is provided on Laing O'Rourke projects for waste streams such as wood, metals, plasterboard, paper and office wastes, canteen wastes etc. Segregation facilitates recovery.

  Laing O'Rourke has supported Uponor Infrastructure, one of our suppliers on our water contracts to achieve the "Environment Business Outstanding Achievement Award" at the City of London Corporation's Sustainable City Awards in 2007 as well as being highly commended in the resource conservation category. Uponor's scheme, begun in 2005 to take back and recycle customer polyethylene (PE) pipes and fittings waste using its own vehicles, has reclaimed more than 260 tonnes of PE so far.

4.  TRAINING AND AWARENESS ON WASTE MANAGEMENT AND MINIMISATION

  Laing O'Rourke includes its procedural requirements for waste management within its environmental awareness courses for its senior managers, environmental co-ordinators and site supervisors. Waste Management requirements are also included in our site inductions. In 2008 Laing O'Rourke will engage its supply chain to start to roll out this training to its key suppliers and contractors.
