PROJECT INTRODUCTION

1.1 PROJECT INTRODUCTION

Unit 22 Agenda (In-)Water Dwelling. Water’s essential nature makes it a strategic natural resource globally. Riparian water rights have become issues of international diplomacy, in addition to domestic and regional water rights and politics. World Bank Vice President Ismail Serageldin predicted, “Many of the wars of the 20th century were about oil, but wars of the 21st century will be over water”. The causes, are many and varied; they include local scarcity, limited availability and population pressures, but also human activities of mass consumption, misuse, environmental degradation and water pollution, as well as climate change. Fresh water — now more precious than ever in our history for its extensive use in agriculture, high-tech manufacturing, and energy production — is increasingly receiving attention as a resource requiring better management and sustainable use. Due to all of this, there is an emerging water industry facing huge challenges for innovation and research. While there is no way to increase the world’s water supply, we can prevent worse circumstances by conserving water and eliminating water wastage altogether with innovative solutions. This could mean a lot of wonderful opportunities to build business leading to a whole new water global geography. Water treatment, Desalination, Agriculture (rainfall harvesting, conservation techniques, small-scale irrigation, animal husbandry), Aquifer recharging, Tourism, Transport, Dredging, Weeds control e.g. Hyacinth, Hydroelectric power for rural electrification, water extraction from wetlands, building of small dams are only some of the examples. All these opportunities could be understood as extensions of domestic and family life. Therefore Water Farms arise as a new civil typology providing both shelter and making life means. On the other hand, from early times, people from the four corners of the globe have benefited from the therapeutic qualities of water joining cultural, religious and health habits in their house’s and neighborhood’s construction. Greek, Roman, Egyptian, Turkish, Japanese, and Nordic cultures have long partaken in domestic hot springs baths and common facilities. Due to contemporary extreme stress in professional life, the spa practice of immersing the body of the person in water to restore and maintain health is again considered to be very important to life. Nevertheless recent specialization of Medicine has pushed Home Spas to daily indulgence in luxurious houses while specializing salutary spas, which are run by medical practitioners to treat users as patients. Latest breakthrough in spa technology involves ultrasonic waves, ozone negative ions and far infrared rays into simple sometimes portable home spa equipment. These equipments provide relief not only from stress but from some common illnesses empowering again the utility of Spa Houses as health preventive agents with considerable importance for welfare state. As a last chosen topic between those thousands related to water, we will focus on water materiality. Monitoring technology can help architecture to get advantage on the adaptation to weather conditions using water as technical support. Eco-friendly features like the water desalination, energy accumulation, ventilation methods, water recycling, heat and energy consumption, tidal and solar energy systems are being developed through empirical procedures. In addition, lots of investigators contribute to the use of water made by biotechnology industry. Biomaterials development requires a deep understanding on molecular hydration and water forces, and how they determine the interaction between molecules, surfaces and forms. A whole range of building solutions and materials are linked to the research on water characteristics enabling to talk about Hydro Materials as a new generation of innovative architectural products. Unit 22 will work throughout two years on water politics related to dwelling opportunities. In this first year, students will produce both design and research on these three topics: Water Farms, Spa Houses and Hydro Materials. A trip to Thailand will be arranged providing a tour throughout the country to analyze the relationship between water and residences in economical, cultural and political terms. Although all the students will be invited to join our Thailand trip for finding the selected case studies, each student will be asked to choose a working area out of Thailand. Students’ works will form all together a constellation of site specific projects around the world revealing the clues for an understanding of new innovative water-based global geography.

Early experiments exploring the relationship between us and how we use water, the transperency of water usage.

PROJECT AMBITIONS

1.2 PROJECT AMBITIONS

Agenda: ‘In the natural world, waste is food […] eco-design should ensure that there is nothing from our human-made built environment that cannot be absorbed benignly somewhere else in the system. My main interest this year is to develop a new reality of living, working and playing. I aim to develop architectural strategies that could generate links and feedbacks between the user and the environment, resulting in a symbiotic relationship in a wider urban context. I want to introduce strategies that would help us to make our cities, towns and villages a more efficient, more healthy and more productive place to live, to work and play. These will transcend the current implementation of ‘green’ and ‘sustainable’ solutions, by tapping potential energies that are hidden in our wastes, or lying dormant or being completely ignored, my aim is to harness and utilise them. My agenda have the following goals: - Strategies that purify waste water with natural resources. Such as plants and marine animals, this is more cost effective and more environmentally friendly than using highly toxic chemicals. - Harness and recycle the many useful elements in waste water. A vast quantity of nutrients we consume in our food end up in the sewer. We should collect these and use them to grow food, to raise fish and not let it be wasted! - Modify attitudes, increase awareness and alter perception towards water usage. I would like to explore and develop ideas that challenge the current water culture. - Reduce water usage and increase water efficiency. Architecture should act as a barometer to how much water we are consuming. If possible, even control the amount of daily water we consume. - Strengthen relationship between communities and its energy and food sources. Due to mass urbanisation, we are becoming disconnected to our biological and natural resources, such as food, water and energy sources. Architecture should allow us once again connect to these life sustaining links. - Generating energy using water and organic waste The potential amount of energy we can harness by using water is vast; it’s free, renewable, and sustainable and will help to cut down CO2 emission drastically. At the same time, we should also be using more organic waste such as dried sludge from sewerage plants to produce energy, our organic waste contain high level of methane, this could be trapped and recycled. - Self-sufficient local communities Our food should be grown within close proximity of our living quarter, our energies shouldn’t be imported from Norway or France, and our waste should be recycled to use as compost for gardening. - The enjoyment of water The experience of using water should be fun, joyous; we should celebrate the use of this precious commodity.

PROJECT BRIEF

HOLISTIC TREATMENT OF THE BODY The treatment centre focuses on alternative medicine such as aromatherapy, herbal therapy and hydrotherapy, and encourage the use of natural, non-chemical based treatment processes. It is also a preventative treatment centre, the use of aromatherapy, can help to reduce stress and relieve anxiety. Aroma treatment room

Aroma garden

Aroma-therapy MIND

Some of the aroma from the aromatic chamber would be allowed to escape and fill the surrounding atmosphere of the sanatorium with beautiful fragrances.

Aromatic Chambers. Where patients would come and inhale the fragrance and scented oils.

Water pumped from river Roding would be boiled to desalinate the brackish water at the same time utilising the steam generated to extract the aromatic oils in the flowers. Which would be then sent to the aroma therapy chamber.

The flower from the horticulral club would be harvested and processed. The organic material ould then be sent into the boiling chamber, where steamwould be used to remove the essential oils away from the plant. The essential oils would be carried together with the rising steam, into the aroma therapy chamber.

Hydrotherapy, formerly called hydropathy, involves the use of water for pain relief and treating illness. It was marketed as water cure by practitioners and promoters in the 19th century. hydrotherapy can take on many forms, but its the generic term includes using jets, underwater massage and mineral baths (e.g. balneotherapy, Iodine-Grine therapy, Kneipp treatments, Scotch hose, Swiss shower, thalassotherapy) and others. It also can mean a whirlpool bath, hot Roman bath, hot tub, Jacuzzi, cold plunge and mineral bath. These treatments use physical water properties, such as temperature and pressure, for therapeutic purposes, to stimulate blood circulation and treat the symptoms of certain diseases.

Herbs are cooked and boiled to create the desired remedy.

PROJECT PROGRAMME

1.4 PROJECT PROGRAMME Recipe for a healthier community:

A new East London Alternative Treatment Centre The new East London alternative treatment centre will be a preventative and alternative treatment facility designed specifically for the local community of Newham, but it would also be open to a wider range of users if required. To enable the building to operate successfully, it will contain the following facilities: 1. A water reception/entrance area

Within easy access from the horticultural club where users of the sanatorium can register and order their treatment. The reception/entrance area will be an extension of the landscape around the building, a green wall and sloped vegetation floor would provide a relax, healthy environment and introduction to the user of the sanatorium. The vegetable wall and floor would also capture most of the natural daylight throughout the day and become the main feature of the space. The reception area is also the first contact point between water, architecture and body. Dirty, unpurified rain and river water would be captured and stored, and where patients can order the exact amount of water required for the treatment programme, thus creating a new system of how people will use their water.

2. A salad bar & herbal canteen

This is where users can sample the fresh produces and salads grown in the horticultural club, while waiting for their consultation with physician and treatment programme to start. Conventional waiting systems in healthcare facilities should be avoided, instead the cafeteria/canteen would become the waiting area, it would also become a source of income for the sanatorium. The herbal canteen would be where patient on the herbal therapy programme can go and have their concoction cooked up with gas captured from the sewage plant nearby.

3. Natural steam shower and changing room

Instead of using mains water in the shower facilities, the new sanatorium would take advantage of using purifies rain water captured in the reception area or steam heated up by methane captured in the Beckton sewage plant.

4. Consultation spaces

The consultation spaces would be where physicians give diagnosis for the patient and decide how the required treatment programme would be carried out. This space would coincide with the natural filtration facilities of the sanatorium; where gravel tanks, marsh ponds and a mini fish farm would be used to filter rain and grey water captured in the reception.

5. Hydro therapy pools

Hydro therapy facility would contain various sized pools for singular or group use. Also the pool would be of different temperatures ranging from 33c-38c. Mechanical access for mobility users. The hydro therapy facility would be a floating structure that rise and fall with the tides. It would be located on the river side, so during hide tide the user in the pool would be metaphorically bathing in the river, this is to create a direct link between the water and the user, and the source of the water they’re using.

6. Aroma therapy rooms

The aroma therapy rooms would be located amongst the horticultural grounds. This is designed to strengthen the relationship between the aromatherapy and the flowers and ingredients where the essential oils are sourced. A naturally scented bed would further enhance the aromatic experience. Aromatherapy rooms would also consist of self-contained WCs and changing facilities.

7. Herbal medicine vault

Herbal medicine storage is where the dried herbal medicines are stored. It is where patient on herbal therapy programme come after their consultation with physician and receive their medications. This storage space also doubles up as a herbal medicinal vault where an extensive herbal medicinal sample are stored for safe keeping and future reference, under this circumstance, the space required need to be in a controlled environment, where temperature, humidity need to be under constant monitor, to safe guard the herbal medicine samples.

8. Tools & equipment storage for horticultural club

Lawn mowers, spades, gardening tools are kept in this area, need easy access.

9. Toilets and utility rooms

Toilets utilising grey and river water for flushing. Water from basins are recaptured and reused again.

10. Administration area for staff

Offices, operational and staff facilities for the sanatorium. The horticultural club The horticultural club is rough six hectors in size and forms a key aspect of the programme, and it co-exists intimately with the three alternative facilities. Firstly, it would act as a provider. A provider of scented flowers, for the aromatherapy treatment, and medicinal herbs for the herbal therapy and salad for the salad bar. It also act as a receiver, the ‘waste’ water from the sanatorium would be collected, stored and used to maintain the horticultural club, where the vast amount of minerals and useful elements would be absorbed by the plants of the horticultural club, thus, it creates a loop, and a feedback, between the user, architecture and the environment. Furthermore, the sanatorium and horticultural club would take into account every single aspect of its surrounding condition, therefore addressing its context and typology. Which currently include, a large scale sewage treatment plant, a tidal river on the Thames estuary, industrial warehouses and factories. At first, these all appeared to be massive problems, but in fact, these rather seemingly unappealing contexts are exactly what the sanatorium and horticultural club needs! The potential of this site and its hidden energies are unparalleled. This is because: • All the energy needed to run the sanatorium could be harnessed from the sewage plant. (methane from decomposing sewerage) • The factories and warehouses would provide the ideal users/patient for the sanatorium. (within close proximity to the site) • All the water needed would be extracted from the river next to the site

Opposite: Initial programme diagram, the alternative treatment centre was first called East London Sanatorium, however, it has since been altered to alternative treatment centre.


PROJECT PROGRAMME

Programme Definition

The Inter-depedant relationship between the Horticultural Club and Sanitorium

Programme & Function: East London Sanatorium cum Horticultural Club

The new East London Sanatorium will function as an alternative treatment centre for those who wish to escape the city without actually leaving it. It will provide an energy efficient and symbiotically balanced environment where a more healthy way of living would be encouraged.

+

The sanatorium will provide an ideal setting where my interests in the relationship between water and users can be further tested, a continuation of the samples and cocktails which I’ve developed earlier in the year. Those main ideas and focal points in which I would like to further explore are:

-Strategies that purify waste water with natural resources. - Harness and recycle the many useful elements in waste water. -Modify attitudes, increase awareness and alter perception towards water usage. -Reduce water usage and increase water efficiency. -Strengthen relationship between communities and its energy and food sources. -Generating energy using water and organic waste

There are obvious challenges in relation to the large scale of the site, but at the same time the potential amount of energy that could be harnessed around the site is unparalleled. This could be a opportunity for a new type of environmental development that takes into account every single aspect of the site context and surroundings, therefore it behaves in sync, in conjunction with the wider urban context. Particular attention should pay to the exact location of the sanatorium and horticultural club so that it doesn’t compromise the scale of the site.

2.0 BUILDING DELIVERY To enable the successful delivery of the East London alternative treatment centre and Horticultural club scheme, one of the most important factors would be related to procurement methods and planning. As the scheme is designed to strengthen the health of the local community, the involvement of this community must be implemented even prior to the planning application and designing process, this is to ensure a design that would reflect the needs of the community. This would be achieved through a series of strategic methods designed to intergrate and engage the local community with the intent, and generating feedback of opinions and ideas through public consultations. It is important to define the clients and major stake holders of the scheme. Project title: East

London Alternative treatment centre and Horticultural club

Clients: London

Borough of Newham, Beckton Horticultural Society

Stake holder(s):

London Borough of Newham, private health enterprises & companies

Proposed funding sources: -Horticultural club -Newham Council -European Environmental Sustainability development Funds -Private health organisations and enterprises

2.1 SCOPE FOR PLANNING The London borough of Newham is located in the Eastern part of the city, the surrounding Boroughs include Tower Hamlets, Hackney, Barking and Dagenham. Together, these few boroughs (including Newham) make up four of the most deprived areas of London, and rank at the bottom end nationally. This deprivation also means there are high levels of unemployment, and that social unrest and all these meant there is lack of development which is crucial to help the borough to overcome its poverty level and be like other areas in London. One major downside of this level of deprivation means the health condition of Newham is also ranked one of the worst in London, all these factors would help to argue more for the development and introduction of a community led horticultural centre and an affordable alternative treatment centre.

Health Action Zone (HAZ) The borough of Newham belongs to the health action zone initiative, which is a government scheme to bring together organisations within and beyond the NHS to develop and implement a locally agreed strategy for improving the health of local people. The ambition of the project is to combat this high level of deprivation and low level of health, firstly, through the setting up of the horticultural club, which would provide a facility where the local community can come and take part in strenuous gardening work that’s good for the health, and grow vegetables which they can consume and even sell. Maybe this could even become a source of employment for some of the local people, as there are no qualifications needed to participate, and they would even learn through taking part in gardening.

2.2 PLANNING STRATEGIES The Alternative treatment centre and horticultural club would be a phased development and each stage of development would involve separate planning applications submitted to Newham planning authority. The two major planning application phases include: 1. In regard to the poor health levels and high unemployment rate Newham borough is currently experiencing, the first objective of the project is the regeneration of the current site, which can be classified as a ‘Brown Field’ site under planning terms1. It would be turned into a series of horticultural gardens and allotments, where healthy activities can be carried out such as gardening, and tending the land. It would also provide job opportunities for the unemployed in the borough. This first phase would take advantage of the government’s Small Holdings and Allotments Act 19082, whereby it states: Section 23, Duty of certain councils to provide allotments.3 (1)If the council of any borough, urban district, or parish are of the opinion that there is a demand for allotments in the borough, urban district, or parish, the council shall provide a sufficient number of allotments, and shall let such allotments to persons, resident in the borough, district, or parish, and desiring to take the same. (2)On a representation in writing to the council of any borough, urban district, or parish, by any six registered parliamentary electors or persons who are liable to pay an amount in respect of council tax, resident in the borough, urban district, or parish, that the circumstances of the borough, urban district, or parish are such that it is the duty of the council to take proceedings under this Part of this Act therein, the council shall take such representation into consideration. Furthermore, it states that co-operatives and societies could be given aid by local authorities: S. 49 Co-operative societies (2)The county or borough or urban district council may for the purpose of assisting a society make grants or advances to the society, or guarantee advances made to the society, upon such terms and conditions as to rate of interest and repayment or otherwise, and on such security, as the council think fit. The council may also let to the society accommodation for the storage or sale of goods. (4)The Board with the consent of the Treasury may make grants, upon such terms as the Board may determine, to any society having as its object or one of its objects the promotion of co-operation in connection with the cultivation of small holdings or allotments.4

2.2.1 PLANNING STRATEGIES contin. After the successful creation of the horticultural community, which should provide a positive incentive for the planners, planning application for the alternative treatment centre would be submitted to Newham planning authority. The application would argue for larger, purpose built facilities that could accommodate the number of increasing horticultural community members, and move from a small scale, local, recreational development to a larger, city wide health initiative where multinational corporations and enterprises can get involved. Because Newham council would be the project’s own client, the building could be seen as a beacon to other community led projects, and a showcase for the borough itself. Therefore, the building must adhere closely to the council’s UDP: Newham council’s first UDP was adopted in 1997, and fully reviewed in 1998 in order to ensure it reflected the Council’sVision.1 In its latest revised edition, 2007, the council sets out the following strategies: (in relevance to the horticultural club and alternative centre) the lists strategies are selected key proposals that could affect the alternative centre: SP1.Successful Places -The facets of healthy communities, quality urban design, successful centres, quality corridors and sustainable development -Place-making visions for new and rejuvenated communities -The desirability of achieving a balance between jobs, homes and infrastructure, ensuring new and existing community needs are met SP2 Healthy neighbourhoods The Council supports health care partners’ efforts to promote healthy lifestyles and reduce health inequalities and recognises the role of planning in doing so through the creation of healthy neighbourhoods and places. -The need to improve employment levels and reduce poverty whilst attending to the environmental impacts of economic development including noise, vibrations and odour and the legacy of contaminated land; -The need for new or improved health facilities, and importance of protection and promotion of local access to health and other community facilities and employment; -The need for new or improved inclusive open space and sports facilities to encourage greater participation in physical activity and provide relief from urban intensity; SP3 Quality Urban Design within Places -The importance of contributing to the creation of genuinely mixed use areas with an integrated range of high quality living-, community facility- and workplace-accommodation, ensuring easy and inclusive access to these and associated walking, cycling and public transport -The importance of minimising environmental impact, with sustainability features incorporated into buildings, spaces and neighbourhoods at an early stage of the design process -An analysis of local character and the specific attributes of the site, seeking to reinforce or create positive local distinctiveness, whilst securing integration and coherence with the local context; -Sensitivity to and capacity for innovation in different parts of the borough, and the need for appropriate stakeholder and community engagement to help direct responsive design; -The desirability of making the public realm attractive as social meeting places to be enjoyed by the whole community, creating a sense of safety and security and helping to prevent crime and anti-social behaviour;

2.2.2 PLANNING STRATEGIES, Newham UDP, contin. 2.Jobs, Business and Skills -Create the conditions to attract investment in the Borough to allow Newham to act as a leading place within London for new and expanding companies to locate and invest [...] There will be an increased focus on strengthening Newham’s business base by reducing its reliance on public sector jobs, increasing entrepreneurship [...] supporting micro businesses and SMEs in emerging business sectors to achieve convergence with the rest of London. J1 Newham’s New Economy -Develop the visitor economy and promote Newham as a sustainable destination, balancing the needs of visitors, the economy, the environment and Newham’s communities, focusing attractions, facilities and quality accommodation J3 Skills and Access to Employment -Improvements to education, skills and training provision, in particular those directed at the growth sectors in the local economy; -Removal of barriers to work for Newham residents; -Promotion of local labour agreements to enable Newham residents to develop skills and secure employment arising from the regeneration of the borough; -Support for employability projects established by the council and other partners where they are working successfully. 3.Sustainability and Climate Change -All Major developments (non-residential) will be required to be assessed against the Building Research Establishment Environmental Assessment Method (BREEAM). It will be expected that development achieve ‘very good’ as minimum (or the equivalent level of any subsequently adopted national standard on sustainable design and construction). -Maximising the efficient use of energy through passive solar design -Re-using and recycling waste arising from demolition and construction, and utilising materials produced and / or sourced locally. -Incorporating sustainable urban drainage systems in line with the London Plan drainage hierarchy, and incorporating water efficiency measures to achieve a consumption target of 105L p/d. -Incorporating living roofs which provide benefits for sustainable urban drainage, biodiversity and the microclimate. -Greening the borough through landscaping, tree planting and provision of natural environments SC2 Energy -Connections to, or provision for connection to, decentralised heat networks (See Policy INF4). -Incorporating on-site renewable energy generation in line with the requirements of the London Plan, and other innovative technologies to reduce carbon emissions. SC4 Biodiversity -Sites of Importance to Nature Conservation (SINCs) will be protected, and development should contribute to their qualitative enhancement, including improvements to access. -Incorporation of living roofs, landscaping and tree planting in developments. In addition, allotments and Tree Preservation Orders (TPOs) should be recognised for their biodiversity value and development should contribute to their enhancement.

2.3 FUNDING STRATEGIES To provide adequate funding to realise the building is one of the major challenges in the project. Initially, it was perceived that the building would be funded by the National Health Service. But due to the financial downturn and the major funding cuts the government is making to all its services, especially in the health sector, it would be ignorant to continue to rely on that source of funding. Therefore, the project looked to alternative funding sources. The phased development is a direct response to this problem of funding. The main strategy is to utilise the landscape to generate a certain amount of income, such as subscription fees to use the gardens, ticket sales for visitors to the gardens, and membership fees for horticultural club members. These would generate a fund that would contribute to the overall budget of building. However, initially, as the project’s client, Newham council would be responsible for providing an incentive fund, to get the project started, on its first phase, such as the horticultural community. As the scheme develops. It hopes to attract larger health corporations and private business enterprises that would be interested to participate in the project, and then provide the rest of the money needed to deliver the building. Once the building is complete and operating, Newham council would get their initial funding back by a monthly or annual profit return. As mentioned, each phase is designed specifically to generate an amount of income and contribute to the overall project funding. To deliver the building, the various funding sources the project would seek from are: - Private businesses and enterprises - Income from renting of the container annexes across the site - The use of the horticultural club - European Environmental Sustainability development Funds - Other public funding sources for community-related developments.

2.4 PLANNING STRATEGIES CASE STUDIES As a precedent, the research into other community led or driven developments around the country is an important step to take before commencing design, by doing so, these projects can demonstrate what elements has worked well, and what hasn’t worked so well. These chosen precedent projects are successful in terms of becoming a social motivator or driver for the redevelopment of the wider community or local area; it gave a useful insight into the requirements of a successful community driven project. Skip Park, Kings Cross The Skip Garden is a mobile allotment on the King’s Cross development site built in partnership with many local partners as an example of organic urban agriculture. The functions of an organic garden are separated into separate skips (including a growing house and green engine) The Skip Garden serves as an educational platform where local children, young people, and business employees work together on tangible projects to improve local sustainability. This is a Capital Growth growing space and an exciting example of organic urban agriculture on one of the largest development sites in Europe.1 The Peckham Partnership Project The Peckham Partnership project is one of the largest estate regeneration initiatives in the country, finished in 2008 after a 13 year construction programme. It was an area of serious deprivation which has been radically transformed and it is now a place where people want to live rather than move away from.2 At the centre of the project is the Peckham library, designed by one of the leading architects in the country, it helped to draw numerous visitors, as it provided an engaging, interesting and welcoming educational space for the local community. Local health standards have also improved with the establishment of Peckham Pulse, the Lister Health Centre, better housing and new public open space and play facilities. The Eden Project Being established as a landmark Millennium Project to mark the year 2000 in the UK, the Eden project in Cornwall not only promotes the education and communication of major environmental issues, it also helped to transform the 160 years old, dis-used china clay pit and its local community into a highly profitable, and popular visitor destination. One of its key contribution to the local community and area is the project’s early decision to source its supplies wherever possible from Cornish companies, be it food goods, plants, other retail items, and even its electricity provider, today it continues to buy from no less than 3,000 Cornish firms.3

2.5 PROCUREMENT STRATEGIES The most suitable procurement strategy for each project is dependent on three major factors; Time, Cost, and Quality. The client need to look at which criteria the end product would likely to achieve, either a high quality finish, meeting the budget or meeting the opening date. In the case of the alternative treatment centre, where the project is developed through various different phases, and each phase would have a different hierarchy of time, cost and quality demand, and pose different relationships between the design team and contractors and client, it is decided to implement different procurement routes for each of the different phases to suit each phase’s programmes, complex site operations, and time, quality and cost demands. The following procurement strategies are all suitable for the project, they include: - Traditional procurement Under the traditional procurement method, the architect is fully responsible for the design; the architect will typically prepare full construction documentation before inviting the contractors to tender for the works, either through competitive tender, or through a negotiated contract. The traditional procurement method would typically employ either a standard form JCT Building Contract, or a JCT Minor Works Contract. Advantages: This strategy is a low-risk option for clients who wish to minimise their exposure to the risks of overspend, delays or design failure. Disadvantages: The exposure to risk will increase where the design phase is rushed, where unreasonable time targets are set or where the tender documents are not fully completed. - Design and build procurement Under a design and build contract the contractor assumes primary responsibility for the design of the development, in addition to its traditional role to supply work and materials. The contractor engages the architect, or more usually, has the appointments of the design team novated to them. Advantages: D&B have three main advantages, these include; single point of responsibility, the main advantage is that the employer does not have to claim against different parties if a problem occurs. Price certainty, D&B offers greater price certainty over traditional forms of procurement, as many design and build contracts include a provision for a guaranteed maximum price. Speed, D&B allows work on site to begin earlier (before the design is complete) than under traditional forms of contract, due to the level of control given to the contractor. Single point responsibility means that the contractor is not relying on other parties for design or for the supply of information. Disadvantages: The main disadvantage of a D&B contract are firstly, design quality, due to the speed and cost of D&B contract, design quality is not usually a high priority and often compromised, Additional design fees. If the employer wishes to take independent advice on design issues following the building contract being entered into, the employer will have to pay additional fees. Lastly, inflexibility. There is only limited scope for the client to make changes or alter the design once the contract has been signed. - Construction Management procurement Construction management procurement involves the client organisation appointing a management contractor whose role is to purely management the project. The client organisation employs the design team, with the client or contract manager employing sub-contractors.The construction manager is responsible for co-ordinating the design, tender and construction processes. Design, tender and construction functions overlap, with construction work divided up into a number of smaller packages, tendered and constructed in accordance with the project programme. Work can begin as soon as design information is available and the tight programming of design drawing packages allows for a rolling tender and construction process. Advantages: Acceleration of the overall project programme; Enhanced ability to incorporate changes into the design; Delayed completion of design elements, such as retail fit-out or hotel fixtures and fittings, that can be finished later without affecting the overall programme; Involvement of specialist trade contractors in design and construction; Creation of a less adversarial, problem-solving project culture.1 Disadvantages: Most of the risks in the procurement route lies with the client, who is also required to be committed to start building on a cost plan, project drawings and Specification only. Therefore the success of the final outcome relies heavily on trusts, between the client, the professionals and the management contractor, who must be well coordinated through all the stages.2

Programme

The project would sit in between programme and cost, as time and deadlines would not be the main concern, where as the final quality and functional requirements are critical.

2.7.1 BUILDING DELIVERY PHASES Phase No. 1 Time: 2012-2015

THE EMERGENCE OF A HORTICULTURAL LANDSCAPE

This initial phase of development will see the current site transformed into a series of gardens, food-growing allotment plots and a wetland marsh area along River Roding’s edge. Newham council will set up the newly formed East London Horticultural club, by attracting local residents, workers in the local industry and horticultural enthusiasts. This club will write a planning application to Newham council, taking advantage of the government’s Small Holdings and Allotments Act 1908, and demand a setting up of a new allotment area, which will occupy the site. Then the horticultural club will elect a board of representative members, who will appoint an official architect, in conjunction with Newham council, to act as advisor for the horticultural community.

THE ROLE OF THE ARCHITECTURAL PRACTICE

The main responsibilities of the architect in this first phase will be the major infrastructural developments around the site: making the site more accessible, the design of a series of canals, and allocating the different areas of gardens, and allotment plots.

Opposite: Plots of horticultural gardens and allotments emerging across the landscape throughout the first phase of development.

2.7.2 BUILDING DELIVERY PHASES Phase No. 2 Time: 2016-2018

CONTAINER ANNEXES CREATED BY THE HORTICULTURAL COMMUNITY

As the horticultural community develops, it is envisioned the visitor numbers and members of the horticultural club will increase significantly. This will provide an incentive to start providing more public conveniences around the site, which will be small structures across the landscape such as tool sheds, seed/compost storage houses, waste storage facilities, public amenities such as toilets, cafes and just places of rest and contemplation. These small structures will be formed of ISO shipping containers, which are readily available around the site from industrial estates and warehouses.

THE ROLE OF THE ARCHITECTURAL PRACTICE

The architect will be responsible for the safe adaptation of the shipping containers into sound structures for habitation. He/she will work closely with structural engineers to make sure modifications of the structure would not compromised the stability of the containers, and the design of the foundations the containers will rest on. At the same time, the architect will have an advisory role for the community, who will be the actual designers of the containers themselves. The architect will be responsible for providing drawings of designs created by the community.

THE CONTRACTURAL RELATIONSHIP

The second phase uses traditional method of procurement. It’s critical that there is a good dialogue between the horticultural community and the architect, as he/she would oversee and approve their final design of the container annexes. It’s recommended that there should be bi-weekly meeting between the horticultural community board members and the architect, and a monthly meeting and debate between the wider community, its board members and the architect. This can occur in the form of public consultations. It’s also an opportunity for other horticultural members to see each other’s designs, for inspiration, and to maximize inventiveness. For this reason, it is decided to use the Traditional Procurement Contract.

2.7.3 BUILDING DELIVERY PHASES Phase No. 3 Time: 2018-2019

INITIAL FOUNDATIONS AND STRUCTURAL INPUT

After a few years when the horticultural community becomes a success, a number of private health enterprises will start to take notice and become interested in joining the scheme to develop the alternative centre. These will become the main funding sources and stakeholders of the project, and mark the beginning of construction work on the building. This will be a three phase construction, and the first phase will be the construction of the foundation supporting structures and steel frame that will provide structural support for the building.

THE ROLE OF THE ARCHITECTURAL PRACTICE

This straightforward first phase would use a design and build procurement route as the foundation structures are relatively simple in design and construction and many elements are repeated in the process. The main goal of this phase is to deliver the product on time and under budget. Therefore the architect will be responsible for providing an initial design proposal of the foundation supporting structure, up to stage E. Due to the route of procurement used for this phase, the initial design will then be tendered out to a contractor for final detailing. The role of the architect will then be novated as under the terms of agreement the contractor will take over the major responsibilities, but the architect can still remain as a client’s agent.

THE CONTRACTURAL RELATIONSHIP

The third phase uses design and build method of procurement. As the contractor will effectively take over the main responsibilities, all the risks are carried by the contractors, therefore this phase will carry low risks. The contractors will be responsible for the final design and appointing the subcontractors and suppliers.

CONTAINER INPUT

After the foundation structures are complete, the series of containers designed by the horticultural community during phase two will be reused as modular building elements for the second phase of construction. These elements will be tranformed into the lower part of the building, which will contain the changing areas, toilets and shower cubicles of the alternative treatment centre.

THE ROLE OF THE ARCHITECTURAL PRACTICE

The architect will once again have a major role in adapting all the different designs of container conversions into a singular, building component. As the architect provided the final designs for these containers earlier in the project, he/she should be the main designer, so this phase will again use the traditional procurement route, where the architect will be responsible for design and management and appointing contractors and suppliers for the entire phase of development.

2.8 THE ROLE OF THE CONTRACTOR Many different contractors will be likely to be involved in this project, and like the architect, the contractor’s role will change according to each building phase’s procurement route. In some cases the contractor will be likely to be responsible for the physical construction of the building and overseeing preparations and site operations during construction. In another scenario the contractor will also become the principle designer of the project, as well as managing construction and overseeing site work. Some of the main contractor groups the project would likely to involve are: -Main Contractor This contractor will have many different responsibilities including design, project management, and sub-contracting and appointing suppliers. -Groundwork Contractor This contractor will be responsible for the major ground and landscape transformation of the site, such as excavations, removal or levelling of soil, digging canals, erecting sheet pile retaining walls, and making the road into the site more accessible. -Concrete works contractor The concrete contractor will oversee the final design and construction of the foundation support columns of the building. This contractor will likely be a sub-contractor to the main contractor appointed by the client or architect. -Steel works contractor The steel works contractor will be another subcontractor whose responsibilities will likely to cover expertise design in conjunction with architects and engineers for the off-site fabrication of the steel roof members, testing for structural qualities of the product before transportation of the roof to the site and finally assemblage of the roof on site.

BUILDING DELIVERY

2.9 THE ROLES OF THE CDM OFFICER The Construction Design and Management Regulations (commonly known as the CDM Regulations) were introduced to make it easier for the different parties involved in construction projects to comply with health and safety duties. The regulations place duties on clients, designers and contractors to ensure the safety of construction workers and also the public that comes across the site. The person who’s in charge of overseeing this regulation is the CDM coordinator. A CDM Co-ordinator, is appointed by the client if a project lasts more than 30 days or involves more than 500 person days of work.1 Their main responsibilities include: -Coordinating the arrangements for health and safety during the planning phase -Ensuring that HSE is notified of the project -Preparing a health and safety report (to enable future cleaning, maintenance and alterations to be carried out safely) Before the architect hands the project over to contractors, he/she should identify the possible risks that might be involved and if possible eliminate the risks through altering design or changing construction process. If the risks couldn’t be designed out, then it is the architects responsibility to inform the contractor or future users of the risks that might occur. During the construction of the alternative centre, the following risks could occur and the designer should inform the following details to contractor: FALLS AND TRIPS Falls and trips is a major hazard in every construction site and it’s currently the main cause of fatalities occurring on building sites. Falling from height is still a major risk factor, which is why concerns such as the safety of scaffolding, walkways, use of ladders and mobile lifting platforms etc. is still of such importance. Areas which have been excavated, untidy sites where building materials have been left out where people can trip over them, and the removal of waste have all contributed to slips and trips which can result in serious injury and, in some cases, far worse.2 TOXIC MATERIALS The use of toxic materials in construction can be a major health hazard, not just to the construction workers, but also to future inhabitants of the building. FIRE RISKS Fire risks are a major concern on construction sites and there should be a proper provision for fire prevention, what to do in the event of a fire and any storage and use of hazardous or flammable materials must also be taken into consideration. NOISE Noise can be excessive with all the various machinery in operation but site managers can often reduce this by sequencing the order of machinery operations to minimise the number of workers exposed to simultaneous noise and proper ear defenders in the form of ear muffs or plugs must be worn.

BUILDING DELIVERY

2.10 THE ROLES OF SPECIALISED CONSULTANTS AND ENGINEERS Building delivery often involves teams of specialised consultants, who have the expertise and necessary skills to solve design problems and solution in conjunction with the architect. To design and deliver the alternative treatment centre, the architect will work with the following specialised consultants: Environmental Engineers To comply to BREAM standards and to archive the high level of environmental sustainability, environmental engineers would play a critical role by advising on the most efficient and natural energy solutions, such as solar and wind energies systems, natural ventilation, rain water harvest. Lift Engineers This specific technician would collaborate with architects and structural engineers to deliver a mechanical method of access and circulation between the ground floor and the lower ground floor. Acoustic Engineers Acoustic engineers would mainly be advising on the design team on how to insulate and protect against low flying aircraft noise, which comes from City airport in close approximation of the site. Lighting Engineers Having a balanced mix of natural and mechanical light source will be important in a health related environment, some areas of the alternative treatment centre would require a soft, dimly lit environment, and other brightly lit space for meeting and congregation, the role of the lighting consultant would come into play under those circumstances. M&E Engineers M&E engineers would play a important role in the designing process for the treatment centre in regard to the design of the complex system of drainage pipes, water tanks, boilers, pumps, filters of rain water. Fire Consultant Fire consultant would help the architect to work out a good emergency evacuation strategy, and fire related building regulations. Structural Engineer The structural engineer would be in constant dialogue with the architect to ensure the structural integrity of the building, they will make detailed calculations and advising the architect in regard to the supporting columns for the LG, the dead/live loads of the LG and roof, and the design of the steel roof supporting structure. Landscape Architect The role of the landscape architect would have a wide consequence across the site. It’s important to determine the type of plantation best suited around the alternative treatment centre, and also across the site, the landscape architect would also be responsible for the creation of the irrigation canals on the site, and the creation of the marsh/Wetland for wild and migratory birds.

The building is situated in a canal basin, the drawings shows the high tide and low tide low of the canal, which is conncted to the tidal River Roding. The structure is supported by re-enforced concrete foundation piles, resting on these piles are the container boxes, which are joined together to make up the shower, changing and toilet area of the lower ground floor. The steel roof members are connected to these container boxes and in the centre is the circulation core, which is constructed from concrete and contains the lift and staircase. The drawing also shows a section of the emergency exit from the lower ground floor, and the methane storage tanks. The drawing also highlights the relationship of the alternative centre and the treatment rooms, which are located scattered amongst the horticultural landscape, a series of raised platforms connect the building to theses treatment rooms.

STRUCTURAL STRATEGIES

3.4 STRUCTURAL STRATEGIES The primary structural strategy is to utilise ISO sea containers as the main structural component, they will provide strong structural integrity to the building, and will carry both dead and live loads. These simple, yet incredibly strong transport vessels can be easily adapted to become modular building elements. A standard ISO 20 foot shipping container weights 2.4 metric tons, and it can support a load of 24 tons, and can be stacked 8 folds. Taking this immense strength to advantage, the building will be using 33 various sizes of ISO container, this give bearing capacity of carrying a dead load of 80 metric tons. There are various important factors that contributed to the idea of using sea containers, these include: AVALIBILITY Surrounding the site are dotted with industrial estates, warehouses and docks, and the abundance of abandoned shipping containers means the chances of warehouses owners wanting to get rid of them to save storage space are probably high. Economically, they are also relative cheap in comparison to other building materials, a second hand ISO 40’ costs $1500 or less,1 STABILITY As mentioned, the strength of a container is unparalleled, however, it’s also extremely stable, besides being able to take loads many times that of its own, the steel frame system provides high level of rigidity, which is essential when these containers are moved across the world on cargo ships, they have to withstand both tension and compression, created from the rolling and movements of the ships. FLEXIBILITY A shipping container can be used as a single module, or they can be combined to form a limitless amount of shapes and sizes as the designer is required. This makes containers very flexible building elements, much like bricks. The steel walls of the exterior can be easily removed, and left with the frame, which can be joined and stacked with other container frames to create bigger, wider spaces.

STRUCTURAL STRATEGIES

3.4.1 STRUCTURAL STRATEGIES LOAD BEARING FORCES DIAGRAM

The main dead load of the building will be the steel roof structure which supports the ETFE skin above and wooden cladding underneath. The weight of the roof is transferred to the shipping containers via the vertical support elements, which is fixed to a steel frame above the containers. This steel frame covers and also sits on the containers. The containers itself are supported by a series of reinforced concrete columns located strategically at every load bearing point (4 corners) of the containers, and it’s fixed by twist locks as used on cargo ships. The reinforced concrete columns will transfer the load of the roof and the containers to the pile foundations which are set 20 meters below bottom of the canal basin.

ACCESS & CIRCULATION

3.5 SITEWIDE ACCESS & CIRCULATION The main points of arrival to the horticultural club are: BY BOAT FROM RIVER ROADING The alternative treatment centre and horticultural club takes advantage the fact it’s located on the water front next to River Roading, and its close approximation to River Thames via the Beckton flood defence gate. Users coming from across the River Roading from the North and Eastern areas would be encouraged to use boat services set up by the horticultural club.

VEHECULAR ACCESS ALONG MAIN ACCESS ROAD There is currently a slip road that runs along the whole western length of the site, this road would be used to become the main access road to the alternative treatment centre and horticultural club where motorised vehicular are needed.

Opposite: the drawing illustrates the main access points into the alternative treatment centre, also it shows the major circulation routes around the horticultural club, which is via a series of canals, criss crossing the landscape.

ACCESS & CIRCULATION

3.5.1 ACCESS & CIRCULATION In accordance to the Approved Building Regulations Document, part M, the alternative treatment centre provides: -ACCESS INTO BUILDING OTHER THAN DEWLLINGS The building have 3 main access points, all with levelled approach and clear access routes that are well signposted and lit and exceed the minimum requirement of 1.5m in width. The building provide 20 car parking bays, which includes the 2400 X 4800mm required standarad dimensions and 3600mm X 4800mm required by disabled users. There are also sufficient spaces in front and behind the parking bay where users can access front and rear of their vehicle. The building has a ramped access at a gradient of 1:20. The total length of the ramp is at 14 meters, with a 2.5m break in between and 1.5m of clear landing at the base and top of the ramp, there are also handrails in each side for support if needed. The stair access have a clear landing at the head and foot of the stairs that exceed the minimum of 1.2m, the surface of the staircase is slip-resistant and contain suitable nosing profile that are contrasting in colours, and balustrade at each side are set at 900mm above nosing. The main access doors have a width of 1600mm, (made up of 2 800mm leaves) which complies with the approved document’s requirement of 1000mm for new buildings, and internal doorways have a clear opening width of 800mm where the approach is straight on, and 825 where the approach is at an angle to access route. -HORIZONTAL & VERTICLE CRICULATION AROUND BUILDINGS The minimum width of corridors inside has a clear width of 1200mm which complies with the regulations, with passing places at 1800mm at intervals. Lift access that can easily accommodate wheelchair users, with handrails set at 900mm high at one side of the lift. -SANITARY ACCOMODATIONS INSIDE BUILDINGS The building provide sanitary accommodations for both regular users and disabled users, at lower ground level. The disabled toilets have clear opening width that allow clearance of wheel chair users and internally it’s installed with the appropriate support equipment and fixtures.

FIRE STRATEGIES

3.6 FIRE STRATEGIES & MEANS OF ESCAPE To comply with Approved Building Regulations Document, part B, volume 2, building other than dwellings. The alternative treatment centre provides adequate protection from fire and safe routes of escape out of the building in case of fire, all the escape routes have a minimum of 800mm clearance in width and headroom of 2000mm as to accommodate wheel chair users. All the emergency exits are clearly sign posted. -Fire doors All the doors are fire rated to hold back fire spread to provide enough time for occupants to escape. These doors are self-closing, so during a fire, they will automatically close to prevent the spread of fire throughout the building. -Smoke detectors and sprinkler system Installed along corridors and consultation rooms are smoke detectors which will trigger the fire alarm if smoke is detected. The alarm can also be manually triggered throughout the building at various alarm points, which is connected to the sprinkler system, and will be activated when the alarm is triggered. The sprinkler will use water collected in the natural water filters. Additional handheld fire extinguishers are also installed at various points inside the building. -Fire escape routes It is estimated that no more than 50 people max. could occupy the building at any one time, the 3 main escape points and along with the emergency escape route at lower level should provide adequate means of escape at a consistent flow rate that should allow all the users to exit the building in time. The approved document suggests the distances of escaping routes should be no more than 45m if one or more fire route is provided, the building escaping distances are as follows:

a-b a-c b-c e-b d-b d-g f-e

37.7 meters, or 20.2 via point c 26meters 8 meters 23.5 meters 31.6 meters 31.7 meters 30.6 meters

-Structure The majority of the steel used for the construction are coated with a layer of intumescent paint. The concrete supporting column have inherently good fire resistant properties. -External fire spread The building is set above a body of water and with no adjacent building next to the treatment centre; the risk of external fire spread is low. -Fire services Fire engines can be accommodated on the car parking area outside the building, and water used to combat the fire can be pumped from the canal the building is situated on.

BUILDING CONSTRUCTION

4.0 BUILDING CONSTRUCTION The construction of the alternative treatment centre consists of 7 different elements, which makes up the overall building envelope, these include: -Concrete and steel foundations that elevate the building from the canal basin. -ISO modular shipping containers, joined together to form the lower ground level. The skin of the containers is left as they are to express the industrial language of these vessels, but the inside of the containers are insulated with sprayed foam. -Steel roof and supporting columns are connected and fixed to the container boxes. The containers will act as structural support. The supporting columns are clad in ply-wood and insulated on the inside to make it water tight as the inside of the columns are exposed to the elements. -In-situ concrete floor is constructed over the steel frame fixed above the container boxes. -External timber cladding for the ground floor. The cladding is connected to the secondary supporting columns to the roof. -Timber cladding for the underside of the roof, these timber cladding have an irregular opening between them, which is used to control the amount of natural light into the building. -ETFE cladding on top of the roof will allow natural light to penetrate the building, but at the same a surface where rain water can be collected.

4.1 IMPACT OF BUILDING MATERIALS AND BUILDNG LIFE CYCLES It is important that the environmental impact of the construction materials have been carefully considered by the design team, and if possible, select materials that can be sourced locally and contains a low carbon foot print. Furthermore, in accordance to approved building regulations document, part D, the materials used for the cavity walls of the alternative centre are all in compliance to the requirements, in regard to the spread of fumes created by urea formaldehyde foam. The following issues should be considered by the design team in regard to the selection of construction materials: -Steel Steel contain high levels of embodied energy, which comes from the manufacturing processes in smelting plants, it is one of the biggest contributors of greenhouse gases, and the extraction process also uses high level of energy. During construction, steel has more volatile organic compound (VOC) and heavy metal (Cr, Ni, Mn) emissions due to the painting, torch cutting, and welding of the steel members,1 The decision to reuse the shipping containers is a direct response to tackle this problem, by recycling this transportation vessels, the building reduces the amount of steel needed both in manufacturing and construction. -Concrete Along with steel, the production of concrete is high polluted, and because concrete cannot be recycled, the building limits the use of concrete only in floor slabs and foundation supporting columns, which uses fly-ash base concrete rather than the standard Portland cement-based concrete. Fly ash is a by-product resulted from common coal combustion processes; it works in tandem with cement in the production of concrete products. The tiny fly ash particles fill microscopic spaces in the concrete better than Portland based cement, and less water is required; concrete using fly ash is denser and more durable. And fly ash reacts chemically with lime that is given off by cement hydration, creating more of the glue that holds concrete together. That makes concrete containing fly ash stronger over time than concrete made only with cement. Using fly ash concrete is also a cost-effective resource. When fly ash is added to concrete, the amount of cement that is necessary can be reduced.2 -Timber Deforestation is a major environmental problem, the increase of greenhouse gases is said to be associated with decreasing amount of forested areas across the globe. To reduce the rate of deforestation, all the timber used in the building are sourced from a managed forests, and are certified by the Forest Stewardship Council (FSC).

4.2 SOLAR GAIN & DAYLIGHTING The treatment centre is situated at an exposed location, and with no adjacent buildings, the centre is exposed to the maximum amount of solar exposure across the daylight period. However, this is utilised to provide maximum amount of natural light throughout the building during daylight hours, this helps to reduce the consumption of energy during daytime.

4.4.2 INTERSTITIAL CONDESATION, DETAILED SECTION, 1:10 The opposite drawing highlights the situation between two container boxes, which is exposed to the elements. The container boxes are inherently sealed against the elements, as they needed to be water tight to carry goods across the globe on ships. However, they are often associated with condensation problems, caused by the difference in temperature internally and externally and atmospheric pressure, this causes water or dampness to occur inside and can lead to rust of the steel shell. To combat the problem of condensation, the container boxes are coated with a layer of anti-condensation paint on the inside of the steel shell. The envolope makeup of the converted containers: Walls: -5mm steel shell of the container -Anti-condensation paint -75mm of closed cell Polyurethane foam, (sprayed) -Steel C channel joists for plaster board support -12mm plaster board Floors: -5mm steel shell of the container -Anti-condensation paint -100mm of closed cell Polyurethane foam, (sprayed) -Steel joists for floor board support -28mm floor board Ceiling -5mm steel shell of the container -Anti-condensation paint -100mm of closed cell Polyurethane foam, (sprayed) -Steel C channel joists -12mm plasterboard

4.4.3 THERMAL INSULATION, DETAILED SECTION, 1:10 Some of the container boxes are joiner together, unlike the previous situation, the internal walls will in this instance span across the two containers, the drawing opposite illustrates the details of the joining and the thermal insulation strategy. As mentioned previously, the containers are insulated on the inside to retain its overall industrial look on the exterior. There are varieties of different insulation that can be used to insulate the container boxes, such as traditional rock wool, but the disadvantage of traditional materials are that they are quite thick to give good insulation properties, and the container boxes do not allow for that much of insulation space to play with. Therefore, the building uses sprayed polyurethane foam insulation instead, this type of insulation sticks to the steel wall itself, and the density of the material means it has much better insulation properties. It comes in a closed or open cell format; the building uses a close cell version as it has the best U-value ratings. The makeup of the converted containers: Walls: -5mm steel shell of the container -Anti-condensation paint -75mm of closed cell Polyurethane foam, (sprayed) -Steel C channel joists for plaster board support -12mm plaster board Floors: -5mm steel shell of the container -Anti-condensation paint -100mm of closed cell Polyurethane foam, (sprayed) -Steel joists for floor board support -28mm floor board Ceiling -5mm steel shell of the container -Anti-condensation paint -100mm of closed cell Polyurethane foam, (sprayed) -Steel C channel joists -12mm plasterboard

4.6 BUILDING MAINTAINANCE STRATEGIES Most areas inside the treatment centre are easily accessible for maintenance and repair works, the most difficult area to gain access into is the roof, which has to be accessed via a step ladder above the life core. Other maintenance strategies include: - Raised access floor of the ground floor can be easily removed tile by tile as to gain access to the interstitial area, which houses all the electrical, mechanical and drainage services. - Natural water filter need to be maintained once in a while and maintenance worker can gain access to this area via compartment opening at the bottom of the filter, or alternatively, there are step ladders fixed to the outside of each of the filter columns, which mean the top area of water tank can be accessed via the roof, for roof access, see above. - If repair work need to be carried out on the concrete foundation support columns or the underside of the container boxes, access is via the canal basin on a boat during high tide. - Cleaning of glazing and external cladding on the southern and western side of the building can be achieved from a cherry picker.

5.0 BUILDING PERFORMANCE 5.1 ENERGY STRATEGIES.

As the name suggests, the alternative treatment centre will seek to gather as much alternative energy from environmentally sustainable or renewable sources as possible. One of the major reasons to locate the centre at this current site is to utilise the unique source of energy that is present adjacent to the site, which comes from the Beckton sewerage plant. Every day millions of Londoner’s wastes are processed at the Beckton sewerage plant, the raw sewerage, left at the settling tanks to be anaerobically digested, produces methane as a by-product of this natural breaking down process of waste. The amount of methane these settling tanks produces is significant, and is a major source of energy that can and should be tapped. Currently Thames Water, which operates the treatment plant, recycles the dried sludge, which is the residue created at the bottom of the settling tanks, it is then burned to produce energy, the embodied methane trapped inside the dried sludge is extremely concentrated, and highly combustible. The centre takes advantage of this alternative source of energy, and will utilise the dried sludge to generate energy to power the building. Furthermore, there is currently another source of energy which the plant is not capturing, which is the methane given off during the anaerobic process, at the top of the settling tanks, the vast amount of methane are left to escape into the atmosphere, which causes more greenhouse gases. The treatment centre will work in conjunction with the sewerage treatment plant, and develop a methane capture system that taps the methane given off by the settling tanks, and directly transfer the gas to a storage tank located next to the building, where it can be used to power generators.

Right: The diagram on the opposite page indicates the drainage and rain and grey water recycle strategies the alternative treatment centre employs. Left: Sewerage plants, a major source of energy, which the alternative treatment centre will take advantage of.

5.2 RAIN WATER DRAINAGE AND HARVEST SYSTEM Reusing Rainfall As one of the main focal points of the design process, the capturing and reusing of rain water is essential in the alternative treatment centre. It is central to the ethos of the design, using an alternative water supply system. The roof of the centre is designed enlarged to capture and provide at least 25% of the annual water usage of the building, at the same time, a series of natural water filtration system would process the harvested rain water, where it can be enjoyed by the users in the natural water shower cubicles. The first step was to look at the monthly rainfall across the city of London, and at the same time estimate how much water the building would need, (approx. 150 litres per person per day), then designing a surface area that would be needed to catch the relative amount of water in conjunction with the size of the roof, and the varies percentages the roof would provide across the months.

Roof development calculations: The water catcher roof is designed to supply up to 25% of annual water usage of the building. The first step was to look at the monthly rainfall across the city of London, and at the same time estimate how much water the building would need, ( approx. 150 litres per person per day), then designing a surface area that would be needed to catch the relative amount of water in conjunction with the size of the roof, and the varies percentages the roof would provide across the months.

Drawing above illustrates the different compartments of the natural water filters. And how it locates inside the columns spacing. Water is captured on the ETFE skin roof, which is set at 1 degree fall, the water drains down on to the pond, and passes through a series of filtration materials, before it’s collected inside the tank and fed into the water supply system in the interstitial floor.

BUILDING PERFORMANCE

5.3 ACCOUSTICS To retain a peaceful environment within the alternative treatment centre, it is essential to provide adequate acoustics protection to spaces where noise levels are required to be kept at a minimum, The location of the building itself does not contain much inherent noise, as it’s far away from any main roads and it’s not in a populated urban area, and there are no other surrounding building in the vicinity of the building. However, London City Airport is less than 2km away and the building is situated just north of the approach and the flight path of the airport, therefore every so often there is a relatively loud noise passing the site, but the frequency of this occurrence are low and the duration of the noise is short. Consideration should be taking into account to give adequate protection from this noise levels, as sudden loud noises can become a source of irritant to the users. The architect will work in conjunction with an acoustics specialist team to resolve the problem of the occasional passing aircraft noise. Within the building, the spaces that are protected from insulation include: Consultation rooms These private clinical rooms have acoustic insulation to prevent the passage of sound between each other, but also due to their close proximity to the lobby, which could experience noise when occupancy level are high, they’re also protected from noise levels coming from the lobby. It is estimated that the rest of the building experiences very little noise, there are no major machinary operating inside the building, and the nature of the building function is low in noise, so areas on the lower ground relies on standard partition walls as acoustics insulation.

The diagram on the opposite page indicates the estimated noise level in the ground floor area. Most of the noise pollution would be coming from gardener gathering on the faceted ramp access, and the waiting area/ cafe in the lobby of the building.

5.4 VENTILATION AND PASSIVE COOLING Utilising the exposed geographical location of the site, the building uses methods of passive ventilation to regulate the internal environment of the building, in particular, the lobby area and the consultation rooms. Prevailing wind comes from a westerly direction. In the western facade of the building, the primary walls are constructed from folding doors, (see next page) this is designed specifically to utilising the prevailing wind, which exits from the columns.

The drawing on the opposite page indicates the folding doors above the faceted ramp access into the building, in the summer months, the doors are kept open, blurring the boundaries of inside and outside.
