M&S is introducing sustainable construction techniques into all future builds – as it strives to become the world’s most sustainable retailer by 2015.

The popular chain will open its most eco-friendly store in Sheffield next month, which has been constructed entirely from recycled material.

The Ecclesall Road store is the first of two “sustainable learning” stores the company intends to open. The eco-friendly measures are part of an overall green programme (Plan A) which has been in operation from the group since 2007.

M&S says the learning shops will help deduce “the most appropriate building techniques” – thus contributing to its overall store building programme.

Built on a brownfield site, the Sheffield store has achieved a BREEAM Excellent rating. Bricks for the project came from a disused mill and the floors are laid with polished concrete.

Heat supply will be sourced from the stores’ refrigeration facilities while rainwater will be recycled for the toilets.

Clem Constantine, director of property and store development with M&S, said: “This store represents a big milestone in our sustainable construction programme as we are installing a host of unique technologies and features.”

“The learnings we have taken from building the store will help us achieve our goal of becoming the world’s most sustainable major retailer by 2015.”

Paul King, chief executive of the Green Building Council, said: “Sustainability is increasingly important in the construction and property sector and major companies like M&S have a crucial role in driving that process, particularly given the relationship not just with suppliers, but also with consumers.”

BuilderScrap would like to congratulate M&S on this move and sees it as a very positive sign both for the stores future as well as the future of our environment.

BuilderScrap recently attended an exhibition at the University of Lancashire (Preston), where I  got the opportunity to listen to several seminars on a variety of topics regarding construction and in particular green building.  One which particularly stood out to me was a seminar by the University of Liverpool research on Developing Sustainable Concrete Products.

The group has had a considerable amount of success in developing a number of sustainable concrete products manufactured using recycled building materials from demolition waste materials. They are still in the developing stages of the product so the product range is currently fairly limited. The existing products that are fully developed for sustainable concrete include:

• Paving Blocks
• Building Blocks
• Paving Flags

These products have been proved to conform to required British and European standards.

The aggregate component of conventional concretes consists of a mix of quarried stone and sand in different size fractions.  These aggregates comprise the bulk of the concrete mix.

In Liverpool, they have conducted considerable research into the feasibility of using recycled building materials as a substitute for quarried aggregates, and the effect of using such recycled fractions on the concrete’s physical properties.

Aggregate derived from recycled concrete can replace up to 60% of the coarse fraction and up to 30% of the fine fraction, whereas masonry-derived aggregate can only replace a maximum of 20% of either fraction.

The University of Liverpool are developing a technique for the complete replacement of cement to produce a cementless geopolymer using waste materials such as:

• Incinerator ash
• Basic oxygen steel slag
• Ash disposed from coal –fired thermal power plants

Combining the replacement materials with waste alkali solutions from existing manufacturing processes, will enable them to develop cost effective green precast concrete products, manufactured from 100% recycled materials.

At BuilderScrap, we love to hear about new innovation helping sustainable construction.  Please contact us if you know of any new ideas or innovations.

Laing O’ Rourke became the first winner of the North West Construction Hub (NWCH) framework tendering process securing the £90m Manchester Central Library and Town Hall redevelopment.

The project which has been designed by architect Vincent Harris includes the restoration of Manchester’s Grade II- listed Central Library and Town Hall as well as redevelopment of St Peters Square. The project is due to be delivered by 2013.

Andrew Jackson, leader of Laing O’Rourke’s Construction North division, said: “Securing this exciting and unique project will enable Laing O’Rourke to build on our solid reputation for delivering landmark projects. It is a complex and challenging project, and one of huge value architecturally, culturally and civically. We look forward to partnering once again with Manchester council.”

This is the first of a number of tenders which will be done through the North West Construction Hub which divides work into three separate frameworks dependent upon project value. The High Value Framework tenders for jobs over £10m and is competed between a total of five organisations, the others being Bovis Lend Lease, Kier, Morgan Sindall and Wates.

The Framework has been developed as a method to ensure that local council can work in partnership with public sector construction in order to ensure that the delivery is efficient and on time. It also shares knowledge and experience as well as creating an emphasis on improved quality and sustainability.

The Labour government’s green school programme has now been scrapped by the coalition, but one school which was built under then the scheme was given the highest BREEAM rating ever for a school. Rogiet Primary School in Monmothshire was recognised as a key example of sustainability and achieved a staggering 78.18% score.

The one-storey timber frame school has 210 pupils and staff, has landscaped grounds and an outside area for sports and play time. This sustainable construction was regarded as of high importance to the former government, not only for reducing carbon emissions and using green building materials but also educating young people for a future of sustainable living.

Throughout the construction, pupils were given the chance to learn about the principles of sustainability, including insulation and what were the best regarding the buildings materials that were used during the process.

Neal Stephens, of construction company Willmott Dixon, who built the school in partnership with architect White Design, commented “The early collaboration of pupils, teachers and the community as a whole was an essential element of the building process and one that went on to reap numerous rewards. The sourcing of environmentally friendly products such as Warmcel Insulation was just one of many innovative ways in which we were able to demonstrate how construction can be sustainable, while creating a learning environment with a low carbon footprint – or in the case of Warmcel, a below zero carbon footprint!”

Other key sustainability features used in the school included:
• Single storey plan with high levels of natural daylight in all areas.
• Timber frame using responsibly sourced timber.
• Natural ventilation using both manually and automatically actuated windows, roof lights and vents to ensure good ventilation rates and thermal comfort.
• Landscape design and planting that increased both educational benefits for the school and biodiversity enhancement of the site.
• Rainwater harvesting tanks that recycle rainwater for use in the school.
• Wind turbine that creates renewable energy for the school.

Derek Downer, Head of Property Services, Monmouthshire County Council concludes “BREEAM set the standards to aim for and encouraged the site team to interact with the school in developing sustainability as an embedded culture, thus encouraging future generations to live sustainably.”

We at BuilderScrap are very impressed with this project and think it was made possible by following a few simple rules; intelligent purchasing of building supply, the use of recycled materials and obviously making sure all surplus building materials go on BuilderScrap.com.

The fifth and final stage of the Buildability Process is all to do with what happens at the end of a buildings life cycle.  Many buildings are demolished, whereas we believe that, wherever possible, disassembly and reuse whould be encouraged and employed. 

The following points should be looked at when arriving at this stage:

Use the reverse of the installation process to minimize damage
Allow realistic tolerances in the deconstruction process
There should be no “false economy” solutions
Identify markets for reused materials before commissioning deconstruction
Engage with all local third sector and voluntary organisations as potential ‘reusers’
Deconstruction/re use supply chain
Look for “outside the box” proactive reuse and recycling initiatives

So that finishes our series of blog posts concerning Buildability – Managing the Lifecycle of Your Building.  The following points offer a summary of the whole process:

1) Minimise the number of different types of components – this will simplify the process of sorting on site and make the potential for reprocess more attractive due to the larger quantities of same or similar items

2) Use an open building system where parts of the building are more freely interchangeable and less unique to one application – this will allow alterations in the building layout through relocation of component without significant modification

3) Use modular design – use components and pre-assembled subassemblies that are compatible with other systems both dimensionally and functionally

4) Use assembly technologies that are compatible with standard building practice – specialist technologies will make disassembly difficult to perform and may require specialist labour and equipment that makes the option of reuse more difficult

5) Provide access to all parts of the building and all components – ease of access will allow ease of disassembly, if possible allow for components to be recovered from within the building without the use of specialist plant equipment

6) Use components that are sized to suit the intended means of handling – allow for various possible handling options at all stages of assembly, disassembly, transport, reprocessing, and re-assembly

7) Provide a means of handling components during disassembly – handling during disassembly may require points of connection for lifting equipment or temporary supporting devices

8 ) Provide realistic tolerances to allow for movement during disassembly – the disassembly process may require greater tolerances than the manufacture process or the initial assembly process

9) Design joints and connectors to withstand repeated use – to minimise damage and deformation of components and materials during repeated assembly and disassembly procedures

10) Allow for parallel disassembly rather than sequential disassembly – so that components or materials can be removed without disrupting other components or materials.  Where this is not possible make the most reusable or ‘valuable’ parts of the building most accessible, to allow for maximum recovery of those components and materials that are most likely to be reused

11) Use prefabricated subassemblies and a system of mass production – to reduce site work and allow greater control over component quality and conformity

12) Provide spare parts and on-site storage for them – particularly for custom designed parts, both to replace broken or damaged components and to facilitate minor alterations to the building design

13) Sustain all information on the building manufacture and assembly process – measures should be taken to ensure the preservation of information such as ‘as built drawing’, information about disassembly process, material and component life expectancy, and maintenance requirements.

The third phase of the Buildability cycle is construction.  The following points should be considered at the construction stage to improve the environmental impact of the build.

Assembly techniques should be compatible with standard not specialist techniques
Plan for simplicity of assembly and logical trade sequences
Achievable tolerances
Energy efficiency and pollution control on site – generators, lighting, plant etc
Vigorous separation and segregation of waste
Consider new, untried site recycling initiatives (plasterboard, paint tins etc)

The fourth stage to be looked at is the management and maintenance of the building and facilities.

If you caught our last blog post about Buildability then you woudl have read all about how Design and Specification fit into the Buildability Cycle.  This post looks at the second phase in the cycle – Procurement.

Sustainable Procurement

The following highlights several points which should be considered at the Procurement stage, to help improve the sustainability of your project.

Standardize procurement procedures
Put local suppliers on procurement framework
Explore compulsory packaging and materials take back schemes
Maximize recycled content wherever possible
Use easily available construction products
Utilise local labour to boost local economies and reduce carbon emissions from transport
Considerate Contractors scheme
Vigorously check the environmental credentials of any potential suppliers

The next stage is construction, watch out for that post.

Well, we are back in the BuilderScrap office after a hectic few days at the Interbuild exhibition.  The show went really well, we met loads of interesting people and signed up a massive new 850 BuilderScrap users!  One of the best things about Interbuild is meeting people from all walks of the construction industry, and seeing how BuilderScrap can be o benefit to them.  We met with some major builders and contractors, councils, charities, colleges and self and home builders. 
We were also running a competition to win a weekend for two in the stunning Coach House Hotel in Chester.  The winner will be drawn next week, and announced on this blog, so watch this space if you entered the competition!
Sustainability Street was a major feature of the Interbuild show this year, with full size intelligent home, hotel pod and a classroom!  We at BuilderScrap were delighted to be involved with Sustainability Street through the display of several boards highlighting the process of Buildability - which will be discussed in a later post.

Here at BuilderScrap, we have recently come across this intersting article on the Sustainable Build website.  The article looks at eco friendly methods of construction and greener building materials.  Here at BuilderScrap, we believe that the reuse of surplus materials can greatly benefit the environment, but there are lots more things people can do.
There is an urgent need to address the great challenges of our times: climate change, resource depletion, pollution, and peak oil. These issues are all accelerating rapidly, and all have strong links with the building industry.
There is a growing consensus from scientists and the oil industry that we are going to reach peak oil in the next twenty years, and that we might have reached this point already. Global demand is soaring, whilst global production is declining, and oil is set to become increasingly expensive and scarce. The building industry is hugely dependent on cheap oil, from the manufacture and transportation of its materials, to the machinery and tools used in demolition and construction. In the UK, it uses vast quantities of fossil fuels, accounting for over half of total carbon emissions that lead to climate change. The built environment is also responsible for significant amounts of air, soil and water pollution, and millions of tonnes of landfill waste. This is a situation that clearly needs to change.
Reducing Energy Consumption
With the inevitability of declining fossil fuels, and the threat of global climate change, reducing our energy consumption is an essential survival strategy. Choosing to build green saves energy. The low embodied energy of green products ensures that very little energy went into their manufacture and production, with a direct reduction in carbon emissions. Eco friendly design methodology can further reduce energy consumption by minimising energy inputs for heating, cooling and light, and incorporating energy efficient appliances. Saving energy for the occupant also saves money – an issue that will become increasingly important as the cost of fossil fuels inevitably rises in the near future.
Building Healthier Homes
Eco-friendly construction can not only help to create a better outdoor environment, it can also help to build a healthier indoor environment. Conventional building materials and methods have been linked to a wide range of health problems. Chemical pollutants from paints, solvents, plastics and composite timbers, along with biological pollutants such as dust mites and moulds are known to cause symptoms such as asthma, headaches, depression, eczema, palpitations and chronic fatigue syndrome. Green buildings eliminate these problems through good ventilation design, breathable walls, and the use of natural, non-toxic products and materials.
There are many good reasons why we should use eco-friendly construction methods and materials. It can improve the health of our planet, and the health of our own lives. It also supports local business and helps strengthen the local economy, which in turn helps to build our communities into vibrant, prosperous and desirable places to live.
A Necessary Choice
Green building is not only a wise choice for our future; it is also a necessary choice. The construction industry must adopt eco-friendly practices and materials that reduce its impacts, before we reach a point of irreversible damage to our life supporting systems. The UK Government is beginning to recognise this urgency, and is committed to integrating green specifications into building regulations and codes, but the process of developing policy is slow. The industry needs to take its own initiative and find alternative ways to build, using green, renewable energy resources, and adopt non-polluting practises and materials that reduce, recycle and reuse, before it is too late.

Todays BuilderScrap.com question for the draft proposal. What do you guys think?

Q: New measures to stimulate action from companies to improve resource efficiency are proposed. Please prioritise these proposals and identify quick win opportunities with high impact.

1. There was a broad level of support for measures proposed. Many respondents ranked all five measures in order while others highlighted those to which they attached particular importance. The results are set out in the table below (NB: as details have been added from those who did not rank all responses, rows do not necessarily add up to the same figure).

2. Some of those who did not rank the measures commented that they were interlinking proposals which would all contribute to waste minimisation but that there was no single “silver bullet”. Some argued that more comprehensive data on waste, waste streams and recycled content material were necessary to underpin a successful waste action plan.

3. On design, there were various comments on the need for standard sizes, greater focus on off-site construction and/or the adoption of lean standards. A number of respondents argued for an extension of producer responsibility, particularly with regard to packaging, so that products could be considered over their life cycle. The importance of full life cycle assessments was highlighted. Others suggested that voluntary sectoral agreements could help deliver targets.

4. Other ideas included broadening the scope of codes of best practice to include more information on waste; greater use of WRAP processes; and greater education across the supply chain, possibly through resource programmes.
