Introduction

[1] Proposed Perspective of the Peninsula 2021

The Thames Tideway Tunnel is a multi billion pound project to upgrade Londonâ&#x20AC;&#x2122;s Victorian sewage system. Because of the scale of the project Thames Water have employed me as an architect to develop a site to demonstrate how they are working to clean up the Thames by preventing sewage overflows. To have the most impact the project very literally allows users to swim in purified water from the Thames that is filtered out naturally without the need for harmful chemicals. Thames water are producing this prototype beach to raise their public image and to prove how clean the are making the Thames Estuary. Teaming up with Sport England who provide the staff and maintenance for the running of the centre when it opens. The main driving factors on this project will be to provide a working prototype beach on time for the opening of the Thames Tideway Tunnel. This is to be completed before 2021 and therefore there has to be a tight schedule as delays could result in the project becoming irrelevant. This report will introduce the chosen site and its context relevant to Greenwich beach which has a long standing leisure use along with the Knight Dragon development which will open at the same time. It will then cover the procurement and its unique design and build process required and how the contract is relevant to providing a finished project on time. Following this the building performance and construction will outline the key requirements to produce a functioning building that has to work with the elements architects normally avoid in a building including how sitting at water level is dealt with..

Water Strategy Conventionally pools use substantial amounts of energy and money to maintain the water within a pool. This project aims to use no electric or chemicals to maintain the water. By careful design and natural filtration the need closed loop systems is removed and rather than chemicals required to clean the water, micro organisms and vegetation live off of the bacteria and help filter out the particulates to clean the water. The heating can be obtained externally by careful design of the depth, width and exposure to wind.

The Park Experience

[1] Aerial Photograph showing site within the proposed Knight Dragon Development _2021

Sitting on the western peak of Greenwich Peninsular the site holds canary wharf as a background and is nestled on Greenwich Beach which was considered the best beach for Londoners to visit in Victorian times. It sits towards the end of the Tideway Tunnel which should have the largest impact on the cleanliness of the water. This master plan shows the site sitting within the knight dragon development which will be finished at the same time as the Wetland Leisure Beach/Park. 6

Historical Site Information

Building Context Historical Maps Greenwich Beach (Blue Line)

Situated on Delta Wharf the site was first commercially used as a metal forgery in 1905 until the early 80’s. Recently it has been used for aggregates until the site was demolished and decontaminated in 2010.

Site(Red Line)

This site sits central to Greenwich Beach which was safe to use as a beach until the early 1940’s at this stage the density of industrial units on the peninsula was increased and the land became more and more contaminated and inaccessible to the public.

The aerial photograph of the Peninsular shows the impact of industrial use on the site, which prevented the site from being used as amenity and leisure. The Vast majority of buildings are single storey and cast little shadow over neighbouring property. Although main access is from central roads away from the river, there is a continuous block of residential, industrial and commercial that weaves around the bends of the river.

Delta Wharf 2015:

The site was home to a thriving beach park along with the active water front for leisure days out and fun amongst the whole family. Large crowds of all types of people would flock to Greenwich Beach as the most convenient location in the busy city to enjoy this unique experience. With access via car, bus and even the river, tourists and locals would not be inconvenienced by a long travel.

The site’s developing rights were brought by Quintain back in 2012 while the rest of the peninsula was owned primarily by Knight Dragon. Delta Wharf and its direct surroundings have been named PQ Phase 1, a high-end private residential (Houses, Mansion blocks and Towers) in the Quintain/Knight Dragon business plan June 2012. In November 2014 Knight Dragon have secured the 100% development rights in a deal worth £186 Million for the remaining 40% share. Currently the site has been levelled, decontaminated and prepared while planning permission is granted. This means that the entirety of the site has a stage 2 stone covering which allows work vehicles and materials to be stored safely while other sites are being developed.

Proposed Site

_Site Flood Map: This map demonstrates the areaâ&#x20AC;&#x2122;s within London that are at risk of flooding from rises in sea level and also areas that can be affected should any of the river flood barriers fail. The current barriers and flood defences in place along the Thames are estimated to keep the blue area above protected until around 2070. There are currently new plans being put in place closer to the mouth of the river that would raise the level of protection whilst also generating Hydroelectric power from the tidal forces. As the site sits in flood risk zone 3, a floor risk assessment will have to be put in place for any new applications, this will limit the positioning and design of certain criteria, including a minimum height for any residential areas.. Original image from Google Earth, Flood data by Environment-Agency

The EA notes that â&#x20AC;&#x153;the flood defence at this location has been damaged. The land owner is responsible for carrying out these repairs and we understand that this will be undertaken at the same time as any redevelopment of the site. In the meantime we require access to the flood defence to carry out any emergency repair that may become necessaryâ&#x20AC;?. 10

Site Density and Usage In 2021

Building Context Figure Ground Map It is important for the project to feel light and open and therefore this plan highlights the density of the buildings surrounding the site. It shows how compacted the residential units are and how the visual openness of the proposed site is required to increase daylight onto the site and in the surrounding buildings.

Building Topologies & Usage (Ground Floor) It is clear to see how the majority of surrounding buildings are residential. However beyond the ring of accommodation lies various mixed use developments that will have a continuous flow of people moving through out the area. The loss of the pre 1960s industrial zones is also clear within this map, although with the increased residential units reducing this use class increases the living standards of the area. This map does not show the extent of the mixed use developments and including the ground floor commercial use of the residential.

Data provided by Knight Dragon Master Plan 2014

Environmental Considerations: 2021

Building Context Site Orientation With the river to the west, and the residential block to the south set back, the site will gain the maximum amount of sun, which will heat the UV enhancing ETFE roof system to provide a constant heat to the building. During the winter the blocks to the east may restrict the sun at first light, although setting the building as far west as possible maximises the solar gain entering the building.

Data provided by suncalc.net

Site Wind Rose The prevailing winds on the site generally come from the South West which means that the high rise blocks to the South and across the river create a shield for the wind, which will prevent the water from cooling to quickly. It allows the heat radiated from the pool to sit on the pool which reduces the chill factor for people bathing.

Site Geology and Make-up

Building Context

Made up Ground Alluvial Silty Clay Terrace Gravel London Clay Woolwich & Reading Beds

Thanet Sands

Chalk Excavation Considerations This geographic location has lost most of its original makeup over the Peat and Alluvial Clay because of how the site has changed overtime. Originally the Peninsula was known as the Marshes, as the whole land was water logged and the soil makeup was not good enough to be used as fertilised land. In the 1800’s with the rapidly expanding industry along the Thames, the Peninsular became a respected area of land, worth developing for industrial trade. This involved raising the land and providing new floor defences to keep the water out. As the Industry started loosing business to developing countries abroad the area became derelict and unused, until the year 2000 when the Millennium Dome’ was built. This required a major investment in removing large expanses of contaminated soil ready for a cleaner public site. Following the Dome the rest of the Peninsular has been regenerated so that all of the ‘Made Ground’ was safe for new development. The site also sits above the London Aquifer which is contained within the Upper Chalk layer. This stores vast amounts of fresh water than can be accessed on demand during a drought. 13

The Fundamental Characters This diagram shows the important factors in designing this park and building. With the main focus on providing usable beaches and associated pools for large numbers of people. It should also be designed with the consideration of expanding on to the rest of the undeveloped land surrounding the peninsular. As the primary space will be for the pools the design must be resilient and practical for withstanding high levels of damp and moisture. 14

This is the extent of the building that will be finished for the opening of the Thames Tideway Tunnel

The site will be expanded for the finish of the Knight Dragon development and capacity increased to allow for increased population and density

As the surrounding area beyond the peninsula increases in population the centre will start to expand around the beaches on the western flank to start to recover the remainder of Greenwich Beach

The Wetlands will start to infill all the unusable spaces to fully re create a safe and sustainable beach in the heart of Greenwich, Global warming will also create an increased demand in outdoor amenity and beach spaces

Site Landscaping Scheme

Building Context

Natural flowers, micro organisms and beneficial bacteria have the ability to break down any organic waste matter as the water passes through the aggregates. This wetland environment only requires a 20:80 ratio of vegetation to water to keep a safe environment for swimming in, how ever this site uses 3500m2 of vegetation for 3000m2 of water to actively clean the water faster. The clean water can be used elsewhere on the site for non vital applications. The plants used consist of submerged plants to oxygenate the water, deep and shallow marginals to intersect small particles floating in the water. Waterside plants and floating plants to remove excess particles from the aggregates. 17

Thames Tideway Tunnel Works Summary

CLIENT AND FINANCIAL PARTNER [1] ThamesTidewayTunnel.co.uk Thames Tideway Tunnel Main Line Procurement Timetable

Thames Water As part of the major ÂŁ4.2bn sewage expansion project to upgrade Londonâ&#x20AC;&#x2122;s Victorian sewage network to prevent overflows into the estuary, Thames Water have been seeking fro an ambitious project to be built along the Thames that can increase awareness of their work. The project has to be bold in demonstrating how Thames Water are working to clean the Thames. The project was chosen as part of a competition its method is to draw a wide range of people from all areas of London and invite them to relax and experience the atmosphere within the warm and vibrant pools.

CLIENT AND MANAGING PARTNER Sport England Is a company set up by the national lottery fund to increase the opportunities for promoting sport. They work on a 50:50 basis with private investors, in this case Thames Water, and can apply their knowledge of running a sports centre like this one through out the design process and then maintain the centre once completed. Sport England can provide a continuous flow of funding for the project once it is running to ensure it is run and governed properly.

The Thames Tideway Tunnel group, set to complete work in 2023 are putting together the initial start-up funds acquire the land and construct the building.

Competition Brief

STAGE ONE COMPETITION BRIEF Thames Tideway Tunnel in partnership with Sport England, is launching a national competition to celebrate the finish of the ÂŁ5bn investment in Londonâ&#x20AC;&#x2122;s sewage network. The competition will be judged and managed by a selection of key consultants leading the leisure industry along with our in-house water engineers. The scheme will lead to a multi million pound project to showcase the achievement made by Thames water in purifying the Thames and preparing our city for the 22nd Century. The site is the former delta wharf on Greenwich Peninsula. Home to Greenwich beach the site drew crowds from all over London during the Victorian times when the original sewer was built. With the completion of the super sewer nearing we require a project to promote the cleanliness of the Thames. The building theme and use is open for the competition and all ideas will be considered for equal merit. The initial phase of the competition will require architect-led, multi-disciplinary design teams to submit designs anonymously. Five teams will be short listed to progress to the second design stage.

Building Delivery

STAGE TWO COMPETITION BRIEF Greenwich Beach Resort Produce a holiday like destination of indulgence where families can take a full day out of their busy lives to stroll along the white sand beaches and dip in the shimmering blue water. The facilities have to be adaptive to the British climate and produce a consistent warm air and water temperature across the facilities. Access is along a singular pathway into the main access point that projects views into the main enclosure, the Olympic pool and the main water purifiers. The entrance then splits into an information centre and the changing village. The centre is to be the first concept to help enhance our local water sources, raise awareness whilst promoting a fun and healthy lifestyle. It is to also be a prototype for cleaning grey water from the surround developments by using natural and solar filtration systems. It then allows visitors to bathe in the glory of re-invigorating the water. Which in turn will substantially reduce the load on the new sewer system. The club appears to float on the edge of the Thames but it must repair the currently compromised flood defence as part of the Section 106 agreement. The main flood defence will be the central platform that will have to match the height of the other local flood defences whilst still retaining the water level views of Canary Wharf.

Proposed Design Team

Conventionally the client would employ an architect to lead the design team and would employ other consultants to liaise with the architect. Occasionally the client may choose to introduce a project manager to help ensure all the consultants are working together more efficiently. This will normally depend on the complexity of the job.

With Thames Tideway Tunnel currently promoting many large scale developments to make the sewer expansion possible, they have employed a project management company to oversee all of their projects, giving the client a single point of reference for managing all of their sites. The client will be dealing directly with the Architect and Project manager to set down the brief. It is then the responsibility of the architect and Project manager to set up a team to progress the initial design and by working closely with Sports Concepts who are a specialist pool design company. This introduces a team of professionals who can assist in the design for industry specific tools required within this development. Once the key design has been developed amongst the design consultants, the drawings will be sent out to all of the consultants who will all liaise through the Architect and project manager, however there will be direct connections between all of the consultants allowing ideas to be transferred quickly without slowing down through the long chains for small items.

Contract Type

Building Delivery

Management Contract vs.

Design & Build Contract

Decision Process The procurement route is very different to a conventional project because of the competition stage. This process as well as the complex nature of the development rule out the traditional procurement route. As Thames tideway tunnel are the driving force behind this project their primary goal for the project is to ensure it is finished in 2021 at the same time as the opening of the super sewer, failure to meet this deadline could drastically affect the image that Thames water are aiming to get across. Secondary to this is the quality and efficiency of the building. The site uses prototype methods in cleaning the water and maintaining a comfortable temperature for customers and therefore it is important that the client and architect maintain the required quality of finish. Option 1: Management Procurement This route of procurement was originally considered as it allows a management contractor to define the packages of work and manage them through separate contracts to sub contractors and the design team. With this scheme being fairly

unknown before the competition closes a management contract would allow a contract manager to be brought on at the start of the project to prepare the contracts required. The advantage of using this contract will allow multiple stages of the project to be tendered separable allowing the piling to start before the detailed design is finished. The client can also rely on an expert company to be organising all of the contracts, reducing the risk to them, as they only have a single contract to the contract manager where as other construction process will involve multiple contracts and higher risk to the client. The disadvantages would mean that the architect and client will lose some of their influence over the project as it progresses. It can also mean that the cost to the client can rise considerably as the price is not fixed with all of the contractors/ Option 2: Design and Build This route would be best suited to meet the primary goal of finishing on time. This way the client can set a clear price and finishing time for the project and then the contractor will then adjust the design

through out the stages of the build to ensure the project comes in on time and in budget. The contract would allow the contractor to employ all of the required design team to make changes when required. If the design team are novated by the client then this would allow the design tolerances to be kept at a suitable level for the finished product. The disadvantages of this route is the expense to the client for aiming to meet the tight deadline with a design that has to work efficiently. The consequences of both of these items failing would result in an unusable centre that could further degrade the image of Thames tideway tunnel affecting future funding. To help ensure the required standard of building can be met there is a need to build a level of flexibility into the contract. This will involve providing key cost saving routes that could be used in the event of the price going over the limit. This would allow the design team to specify cheaper products that can still meet the standards.

Regulations and Public Bodies Following the competition when a winner has been announced and a contract agreed, there is a series of legislation criteria that have to be met within this site and for this specific project. The Pre-Application outlines that the policies to be met are: • NPPF (National Planning Policy Framework) - Promoting Healthy Communities • NPPF - Meeting the challenge of climate change, flooding and Coastal Change • Local Planning Policy - Royal Greenwich Local Plan • Local Planning Policy - Active and Healthy Communities Secondary to the planning policies, Sport England have developed a set of guidance documents to ensure leisure facilities are designed and built with maximum compatibility with disabled access and safety guidelines as follows: • Sport England - Accessible Sports Facilities • Sport England - Artificial Sports Lighting • Sport England - Swimming Pools • Sport England - Outdoor Sports Surfaces

The client During the first stage has consulted BREEAM, Highways Agency, CABE, Environmental Agency and the Port of London Authority. These contacts are very important for arranging any changes to the sea wall, Thames river bed along with site access and building sustainability. It is very important for the client to achieve the highest sustainability rating within the site, as a way of proving the efficiency and care Thames Water place into the environment. Conventionally this is very difficult for a leisure centre as substantial amounts of energy is required to clean and heat pool water and maintain a consistent environment within the large expanse of internal space. This site however attempts to remove the high up-keep costs involved my using sustainable methods of cleaning and heating the water. The natural filtration system requires no electricity and a significantly smaller proportion of space to clean the water, along with solar and ground source pumps for heating the water, which in turn heats the air above the water. Planning Policy has stressed the importance of maintaining the full flood protection on the site through out the works and building life span, this means that temporary flood protection is required before any work can start on site. The utilities for the site are primarily off

grid and so only the essential building services require consultations with the utility company, which following a major services upgrade for the Knight Dragon scheme should not require any increases on power demand. Also the change of use from industrial to leisure means the site power requirements will have reduced. The council consider this development inside their local area action plan for the peninsula and the amenity is greatly needed amongst the major residential developments which have not met the minimum space standards. Phasing To ensure the project completes in time for the opening of the Thames Tideway Tunnel and the PQ1 Phase for Knight Dragons development, the scheme has been phased on a very tight time scale. This will allow the opening to have maximum impact and awareness in Greenwich. Construction The initial site preparation will start before the technical scheme is finalised, this will allow all the temporary flood protection and service routing to be completed ready for the main construction contract.

Risk Assessment

Design Risk Factors Client Expectations - Should the client have higher expectations than possible for the budget Building Control Expectations - As this scheme is a hybrid between functions the regulations for conventional buildings may not be achievable Communication Errors/Delays - With a large number of consultants this could cause delays and extra work. Drawing Delays - Changes to design Design Team Consistency - The drawings require a high quality control to ensure design is consistent Design Team Competence - The whole team must work together to minimise errors

Building Delivery

Delivery Risk Factors Collating Warrant arrangements Material availability Material price fluctuations Specialist staff and contractor lead times Delays or refusal of planning permissions Delays due to litigation Unexpected water purification affects Experimental water processing systems may be ineffective

Construction Risk Factors Temporary sea wall must be secure to protect the site and workers Large machines for piling and excavation present high risk to foot traffic Retaining walls presents risks of stability during construction Working at heights around excavated zones and on the higher level building Existing on-site services may not meet new site requirements Excavation could lead to archaeological finds affecting time scale Excavation could uncover unexpected ground conditions Excavation could uncover unexpected services, pipes or utilities Working below tide height could result in flooding Co-ordination between trades to ensure delays are not created Unavailability of materials Co-ordinating traffic with Knight Dragon construction

Building Construction

Roofing/Plant System The central building acts like a green house to enhance the solar rays passing through which helps to heat the internal water and air temperature with a concrete based cladding to assist as a thermal mass for storing heat.

Entrance and Building The main access is to the South East and allows visitors a high viewpoint over the site before descending into the beach scape. The central building is the main access point for the pools allowing fast and slow ramped access with a â&#x20AC;&#x2DC;lazy riverâ&#x20AC;&#x2122; to allow the body to acclimatize to the water temperature.

Site The majority of the site sits at the maximum theoretical high tide level allowing water to flow in at high tide. The floor barrier surrounds the site while the entrance is protected from flooding. Surrounding the building is an array of filtered streams and beaches for swimming with sections for the vegetation and purification of the water.

Each platform has a different surface according to its location, either a dry white sand heated from a ground source heat pump, sunk vertically from the shaft. Or a lush grassland suitable for radiant and exotic planting that can thrive in the heat from the surrounding sources. The construction consists of a concrete composite frame built from the fly ash as a tribute to the iron furnaces that were used on this from 1782 to 1892 by the Foxbrooke Ironworks and then Appleby & Company. This frame then hold the sand, grass or pathway above and a metal frame below allows the formation of crystals from the heating of the water. The central column is dug down into the geology, deep enough to secure itself against the solid materials with a chance of it sinking into the aquifer. Platform Section

Glass Fibre Reinforced Concrete Panels(GFRC) As the roof is self supporting the walls consist of a lightweight steel frame that allow for GFRC panels to be fastened to the facade creating a wind and waterproof barrier. This wall will contain a high amount of insulation to account for the ETFE roof. The concrete cladding also works as a thermal mass to retain some of the heat and release it slowly when required. This frame is built off of a strip foundation that will be connected to the steel columns for the roof creating a rigid structure.

3.04 Primary Structure

Primary Columns

Primary Support Trees The primary structure consists of a series of trusses supported by tree like beams, these have a slim profile and help to reduce the flex at the joints when the roof area is being affected sideways by the wind. The main trusses span across the indoor pools allowing for a view all the way through the centre.

Primary Truss

Building Construction

Primary Structure The space frame, roofing system has a substantial mass which is supported by its own columns on Pile foundations. The structural grid is not uniform because of the shape of the building however the maximum span is 10m with the average at 6m. The space frame is a series of interlocking trusses that provide a rigid triangulated structure for the roof to connect to..

3.05 Roofing System

Building Construction

Roof Truss In order to produce a large roofing span across the pools without excessive columns a space frame has been used, this helps to keep the entire roof rigid in high winds and under extra load. The space frame also allows for the thickness of beams to be considerably reduced so that more light can pass through, especially during the winter when a thick â&#x20AC;&#x2DC;Iâ&#x20AC;&#x2122; Beam would conventionally block all light.

ETFE To maximise the amount of light and heat that is transferred into the building it is important to use a material that can enhance the solar gain and then react quickly to restrict or increase the amount of light transmitted to regulate temperature. Triple layered ETFE panels are very effective at this, by adding a third sheet between the inner and outer skin. This is etched with a pattern that when pushed towards the outer skin allows the maximum amount of light to pass through however if the air is transferred between the chambers the etchings join together to prevent any direct light from passing through.

3.05 Roofing Materiality

Building Construction

Glass Roof Finish Advantages • Optimum price in medium sizes • Readily available resource • Various coatings to change characteristics • Many colour options • Provides rigidity to structure • Different thickness’s increase insulation • Self Cleaning Option • Little maintenance

ETFE Roof Finish Disadvantages • Heavier than ETFE • Requires bulky blinds to change solar gain • Expensive in large sizes • Very fragile

Advantages • Available in any sizes • Cheaper for larger spans • Changes quickly for solar gain • Lightweight • Can have added patterns • Higher resistance to breaking • Lightweight frames allow for opening panels

Disadvantages • Colour finish limited • Specialist design required • Expensive in small panels • Plant Machinery required • Pressurised system uses electricity

Final Decision There are different considerations required for the final roof material. Both options can provide a similar result both with advantages and disadvantages. With the main intention to use ETFE because of its ability to adapt quickly to changes in the amount of light however the additional plant required to maintain a roof like this could result in poor design finishes if not fully considered. 37

Beach Sectional Perspective

Clean and heated sand One of the most appealing characteristics of a beach is its cleanliness and warm touch on the feet. In order to artificially enhance the British weather sections of beach will heat the sand using a ground source heat pump along with a pressurised under floor piping system. As this project relies on a natural filtration system it means that the plant life actively pulls the bacteria out of the system and during a high tide the water level can be raised to clean the sand slowly without washing it away.

Thames/Pool Separation To top up the pools at high tide, barriers within the separating wall can be opened to allow water to filter through into the pools. The barriers contain an array of filters the remove all of the harmful particles on entry allowing the internal circulation to work more effectively. The barriers also include an automatic flood barrier that will raise when the water level gets near the top, this works by allowing water to flow into a small reservoir which will force the barrier to the required height without any electricity or human intervention.

Excavation Process

Existing Site 2016 Because the site was contaminated from its previous use when the existing Delta Wharf was demolished in 2008 they removed a large amount of the contaminated ground replacing it with stone chippings (20mm) so the site could be used for material storage for the construction of the Knight Dragon Development. The first stage will be to clear the chippings and store for use later, then install a temporary flood barrier to prevent the site from flooding.

Building Construction

Mid-Construction 2017 Then sheet piles will be installed around the site while excavation starts, with a temporary ramp being built for machine access.

Finished Construction 2018 Once the full excavation has been completed and the concrete water filters have been installed with automatic flood barriers the temporary piles can be removed and re-used on the next site.

BUILDINGPERFORMANCE

To develop a fully sustainable pool, this project uses all natural filtration and heating systems that would naturally occur in wetlands. Conventional pools use substantial amounts of expensive unsustainable energy to attempt to imitate nature.

Site Strategy

Building Performance

General Energy Strategy The most important factor if this project is proving how Thames water are working to clean up the environment, therefore this site has to use as little energy as possible. Conventionally the highest expense within a leisure centre is heating and cleaning the water, within this site it has been designed with natural and environmentally friendly systems that rely on nature. The water is cleaned by vegetation and heated by solar and ground energies. All of the other general principles stem from these technologies. 42

This allows large amounts of water to be saved in the process. During the winter it will also allow more heat to be re-directed to the pools that need it.

Filtering Thames Water To prevent any bad or harmful particulates from entering the pools they are filtered out at the separation barriers between the Thames. This kills off bacteria and removes particulates from the water using an array of filters that can be cleaned by simply draining clean water backwards during a low tide. 46

Internal Purification The water is naturally cleaned using vegetation as listed in the site landscaping scheme. Because of this design the water can clean itself completely and safely without the need for electric. However to heat the water higher than the average 21 degrees that this shallow pool will keep it at, the pumps send water to the solar distillers which use the suns energy to heat streams of water and also kill any extra bacteria not removed by the vegetation. 47

Ground Source Heat Pump

Internal Heating The primary function of the ETFE roof is to enhance the solar radiation passing through to raise the temperature of the air and water to suitable temperatures. This is created by a south angled roof that can direct the sun at the water and concrete floor to build up the temperature and then adjust the ETFE to prevent overheating. This also creates air circulation by pulling in air through louvred vents low down also pulling in cool air over the external pools to produce a sensible humidity. The air then raises and is vented through the roof. 48

Secondary Heating To prevent the warmth from escaping with the exhaust air the steel frame for the ETFE roof also works as a large scale heat recovery system. Water can be collected at high level and then flow through the steel pipes on the inside of the roof warming as the water drains down, allowing the exhaust air to cool and then the heat can be transferred into the underfloor heating system below the pool. This can create a continuous look ensuring heat is kept within the centre.

Internal Ventilation As summarised on page 52 fresh air can be pulled in at low level from under a canopy, heated inside and ventilated at high level using a heat recovery system. As more heating will be required during the winter and additional rain can be collected the louvres will help to work as a heating element, water from the roofs heat recovery system can be re-directed to flow through the louvred panels heating the air as it passes over. Trees and vegetation will also protect the vents from gusts of winds allowing the air to trickle through as required. 50

External Water Heating

Building Performance

Solar Still/Pasteuriser: Filtered water and recirculated water is pulled in through the filters at the bottom and into a reservoir. Copper tubing used to frame the device is heated in the sun and causes a convection current to pull the water through the vast extents of tubing, heating the water substantially and expelling it where required. The water is then run through clear pipes behind an IR and UV enhancing film and glass that focuses the suns rays to kill off any remaining bacteria that may exist in the system. This Heating mechanism sits within the clean pools and circulates the water to ensure it stays clean whilst allowing the pools to be heated through the radiation provided by the sun, saving 3KW per litre of water. 51

External Intake As this site takes in water from the Thames it means that the water level will always be equal to the high tide of the river. Therefore a fixed flood defence system cannot be installed at the edge of the site without being compromised by the intake valves. Therefore the site has been designed placing all of the water resistant spaces at this level and raising the important parts above the flood defence line. As this is a leisure centre the majority of the surfaces and walls have to be built to withstand water penetration. Therefore rather than preventing flooding this site actively works with it. The primary focus of the site is to clean water from the Thames, in the event of a flood water will flow into the site and be purified and cleaned by the natural filters, allowing the water to be held until it is safe to discharge the excess water, then the surfaces can be cleaned and the centre will return to normal. During a minor flood, the automatic flood defences built into the outer wall will raise up automatically with the height of the water to a maximum of 2m above the maximum theoretical tide. 52

Acoustic Strategy

Building Performance

Minimising Airborne Sound This site does not separate any living or work spaces and therefore does not have to meet guideline sound testing, however to enhance this environment dense low level vegetation is used frequently around the large number of narrow beaches. This helps to prevent sound travel between sections. This system works internally and externally. To increase efficiency internally, shrubs and plants will be added around the walls to prevent reverberation. 53

Fire Strategy

Building Performance

Escape Routes Although around 50% of this site is water it is important to include a safe means of escape from the premises that minimises smoke inhalation and includes multiple exit routes. The majority of the site is outdoor, however to escape the width of the stairs and ramp has been determined by the capacity of the pools, including 2 emergency escape ladders along the banks of the river.

Fire Strategy

Building Performance

Escape Routes Building regulations states that this premises would require a maximum travel distance in a single direction of 18m or with two exits 45m, It is also important to consider that the customers must be able to get back up to street level without causing a hazard on the stairs. This can be achieved with multiple exits around the building that lead onto walkways back to the primary access.

Lighting Strategy

Building Performance Low level Outdoor lighting Energy Efficient lighting that provides a low light level during the night to create a relaxing atmosphere. Charged by Solar Panels during the day.

Vibrant Indoor lighting To ensure a continuously high lighting level for the indoor pools simulating day all the time

Circulation lighting The main circulation requires sufficient lighting for customers to safely access all parts of the site safely.

Ecologically Friendly Lighting The lighting of this space requires a sensitive approach that does not use excessive energy consumption and is also fully water resistant. Therefore the majority of lighting will be lowvoltage LED fixtures powered by solar panels mounted to the surrounding retaining walls. The low voltage lighting can also be submerged under water to help create a relaxing environment minimising light pollution. 56

Off-Site Manufacturing On-Site Installation

CONSTRUCTION PROGRAMME PRE-CONSTRUCTION PHASE The construction will be carried out in 2 phases and 2 separate contracts. The first phase will be the site preparation works to install the temporary flood barrier and prepare the service runs to site ready for the main contractor. This will be carried out prior to the final tender ready for the main contractor to start on the 1st of September 2016.

CONSTRUCTION PHASE Once the contractor has been chosen the contractor will have a one week site preparation period and then main sea wall piling and excavation can begin, there are overlaps in the time frame for this, as the large extent of the site will allow for progressive excavation to the middle and front while the surround walls are put in place. During this time, the steel frames and

concrete platforms will be manufactured off site ready for a quick installation once the ground works are finished. The main building because of its size will allow a large amount of sub-contractors on site at the same time to complete works in stages. 63

Stage 1

STRATEGIC DEFINITION

PREPARATION BRIEF

Thames Tideway Tunnel and Sport England form a team to prepare the initial brief for the project. This involves scouting out different sites and themes for the wetland leisure park. It has been outlined that the design and architect will be chosen from selection of competition entries, this will allow a public relations committee from the client to evaluate the best way forward for the company to raise the public image and prove how they are working to clean up the Thames and fix the problems of raw sewage. It is also important to build up a connection with Knight Dragon at this stage to ensure future stages can work without interference from the two developments.

The client takes on a project manager to start the competition process and further the brief. Thames Tideway Tunnel budget analysisâ&#x20AC;&#x2122; prepare a draft budget outline to inform the project manager of the extent of works allowed. This project is considered a prototype development and also the main public project that will help to increase the funding for future Thames water Projects. The Project manager prepares the brief for the competition posted on the RIBA website.

Stage 2

Stage 3

CONCEPT DESIGN

DEVELOPED DESIGN

The Wetland Leisure Centre project has been won at a two stage architectural competition. The winners have been chosen by the public relations committee along with advice received by guest judges to advise based on technical aspects of feasibility the projects. The winning architects then prepare a set of documents for a pre-application process and appoint design consultants . Basic sustainability statements are prepared and the client provides details on how sustainable they require the project to be to ensure it raises the company image sufficiently. A quantity surveyor is brought on board to evaluate the concept design and prepare a summary to present to the client before the scheme progresses.

Taking on planning advice from the preapplication planning meetings, the design team can work together to progress the design and cover design details that may have been excluded from the competition. Sports Concepts work closely with the architects and landscape architects to introduce the specialist designs required within a leisure development of this scale. Meanwhile construction and Health and safety strategies are produced based on the assumed works and revised cost schedules are presented to the client. The revised design is then submitted to the planning authorities as an outline proposal because of the extent of the works. On site tests and prototypes can be carried out to calculate the water purification, turn over and heating requirements.

HANDOVER AND CLOSE OUT

IN USE

A full set of tender drawings are produced in line with all of the sub-consultants. At this stage all of the consultants gather for weekly meetings to present and overcome technical factors on the project. The drawings are then sent out to an initial 5 contractors for comprehensive pricing breakdowns that are overseen and checked by the Quantity Surveyor. After negotiations with each contractor if initial discussions are considered appropriate then the quotes are presented back to the clients who can choose a main contractor to take on all of the works under a design and build contract. The contracts can then be drawn up along with finalising all the risk assessments, handover, maintenance and operational strategies.

Site preparation can begin, removing the contaminated land and excavating the land and pits for the swimming channels. Meanwhile the majority of the building and water filters are manufactured off site and prepared for transport to site. It is the responsibility of the contractor to ensure the budget set out in the contract is reached and therefore the largest contingency is likely to be in the ground works and therefore the contractor will have to liaise with consultants to ensure specialist purification features are not compromised by any cost cutting requirements on the contractors side. Once ground works are completed all of the building components can be transported in via the roads or water ways and craned into position and assembled.

As this project is highly experimental to attempt to purify the Thames water, a series of specialist consultants will be brought in to test the success of the design and technical aspects to ensure the water is safe for public use and any snagging is carried out. Any defects under the contract is shown to the contractor to rectify before sign off. Any factors that may require further changes are pointed out and carried out separately. As soon as the water ways are prepared, the Thames water will be filtered in and the managing company will be testing for the required turn over rates and training staff to ensure a safe environment is maintained.

The In Use services are carried out in accordance with the Schedule of Services and all of the research from the previous stage is collated and scrutinised ready for future projects. Sport England take over full ownership and incorporate a management company in charge of maintaining the centre for an initial fixed term of 4 years.
