1.1 Response to the brief
1.1.1 Unit brief: ‘Frontiers of resilience’
‘We live in a world populated by structures – a complex mixture of geological, biological, social and linguistic constructions that are nothing but accumulations of materials shaped and hardened by history’ 1 Over 450,000 years ago nomadic tribes roamed the mud lats and marshlands of a vast river, their migratory patterns in luenced only by the proximity of food, fresh water and high ground, scavenging for survival in this harsh place. Millennia passed, the last ice age ground to a halt with melt water submerging the land bridge of Doggerland, a tsunami engulfed the lowlands and created a new island. Over the eons that followed, a booming metropolis grew on the banks of this new river estuary. In 2015, London has grown to its largest size ever, with population igures topping those of 8.6 million2 set in 1939 and continuing to grow.

Huge infrastructure projects like Crossrail and the ‘Super Sewer’ go way beyond the pioneering visions of Bazalgette and Brunell. Failed proposals for an esturial airport replace the migratory visitors to our shores with a species of more metallic and oil hungry. Our priorities and challenges have shifted since those original settlers irst made marks on the land, civilizations have lourished and our support structures have become increasingly complex. Reliance and dependency create a new vulnerability. Natural, economic and humanitarian disasters are shaking the rickety foundations of consumerist culture and opening our eyes to the possibilities beyond. Future resilience demands innovative solutions which rethink our relationship with climate and resources, land-use, nature and technology. The impacts of urbanisation reach far beyond the shifting and demarcated boundaries of the
city. These ‘edgelands’ beyond the urban are the contemporary Libertines, chasing new frontiers of identity. This year UNIT 3 will be working on this edge zone, as an exploratory ield around the city. We will develop adaptive spatial strategies, focusing on the duality between architecture (physical) and infrastructure (social) to address the challenges posed in an uncertain future. Our initial investigations will be universal, siteless and collective, based on themes of shelter, sustenance and climate, before focusing our explorations on an eastwards trajectory into the Thames Estuary.

1.1.2 Personal response to the brief ZZZ DUFKLWHFWVMRXUQDO FR XN
Unit 3 began the academic year with a series of workshops on the themes of sustenance, climate change, shelter and resilience. Since the early start of the year I have been interested in climate change and design opportunities that may come with it. For our workshop on climate change we were asked to imagine a future scenario for the year 2030 and the consequences of climate change on a chosen topic. We then produced a piece of writing to support our theories. The article I wrote for this workshop was about the consequences of looding on the Thames Barrier (see ig. 3). I imagined that in 2030, due to increased loods, a new barrier may need to be built across the river Thames.
The series of workshops, other than having the function of bringing people to get to know each other and work together, set the scene for the two main projects that follow, the irst entitled ‘Personal Adaptor’, the following one ‘Island Incubator’ (the main building project). For the ‘Personal Adaptor’ project students were asked to imagine a future scenario (linked to the themes previously treated) and design in response to it a piece of equipment, a map, a vehicle etc. Still referring to my earlier article, I designed an amphibious vehicle (see ig. 2) which would allow transportation in very dynamic climate conditions and boost river transportation through the river Thames.

Context and introduction 1.1 Response to the brief
1.1.3 Project brief: ‘Island incubator’
After the completion of the ‘Personal Adaptor’ project, we were given the brief for the main building project, entitled ‘Island Incubator’. The site for the project is the Isle of Sheppey, located at the Thames Estuary ( ig. 4). The brief is as follows:
Our investigations will focus on: • Outposts, edgelands, periphery • Future infrastructure and impact on the built environment • Resilient communities in a dynamic environment • London’s rapid growth and changing land uses
Our exploration of resilient design strategies now continues into the Thames Estuary. Strategically located and for centuries the ‘gateway’ into London, the estuary is today a periphery, characterised by large infrastructure projects supporting the city on the one hand, and its rough natural beauty on the other. As a relatively underdeveloped area in close proximity to the metropolis, this edgeland is often earmarked for future development. But how can this be done in a sustainable way, taking into account that much of its land being threatened ϔloodrisk?
Proposals will be based around our initial research and developed around the following ten themes: • Food production and consumption • Cultural enrichment and preservation • Learning and development • Health and social support • Recreation and wellbeing • Transport and movement • Dwelling and settlement • Protection and refuge • Governance and community • Trade and manufacture

1.1.4 Concepts underpinning the project
While each of the 2nd years students were given a site before the actual site visit, 3rd years were free to choose their own. Before going on site, given the size of the island, I gave a quick look at the Isle of Sheppey on google maps to try to identify an interesting site for my proposal. From google maps, one of the irst thing I noticed was the northern coast of the island being affected by erosion. The site visit (see pictures at pages 16-17) con irmed the impression I had by looking at the site from above on google maps. I got more interested in coastal erosion and decided that the proposal should have been strictly related to it.
10
The erosion phenomena is quite signi icant on the island and has en enormous impact not only on the coastline, but on everything that sits behind it (communities, caravan sites, habitats etc.). The irst idea for the project was to design a defensive structure, a sort of seawall, to protect the coast from further erosion. The idea of a seawall rapidly evolved and turned into a research facility where coastal erosion and the natural elements that cause are studied in depth. Rather than protecting the coast itself, as initially thought, the coast itself becomes a sort of testing ground where research is carried out.
While I initially located the research facility along the coastline, I then decided to design a pier structure which would strecth towards the sea, and locate the main research facility at the end of the pier. By doing this the research facility looks back at the eroding coastline rather than sitting within it. The facility researches all those elements which are the causes of coastal erosion: sea waves, tidal range, weather and others. To link the proposal with the coast a secondary facility is designed, a smaller research center were ground conditions and sediments are studied. The pier structure and the secondary facility are linked by a staircase that provides access to the site from the mainland.
While the secondary facility is of private use, the rest of the proposal (staircase, pier and main research facility) is open to the public. The reason for opening the research facility to the public is to promote awareness of coastal erosion but not only. The proposal in fact creates a strong link between local communities and that part of land which would otherwise be inaccessible to the majority of people.

1.2.1 Coastal erosion in the UK
Coastal erosion is de ined as â&#x20AC;&#x2DC;the breaking down and removal of material along a coastline by the movement of wind & waterâ&#x20AC;&#x2122; (GeographyAS, 2012). It contributes to de ine the pro ile of the coastline as well as the formation of any landforms. The coasts of the UK are historically known to be widely affected by coastal erosion. Important investments are made every year to protect all those coastal areas considered at risk with the creation of temporary/permanent difense systems ( ig. 6). Predicting erosion rate is an uncertain science. However the foreseeable changes in climate are expected to increase erosion rates in the near future.

Context and introduction 1.2 The site
1.2.2 The Isle of Sheppey
The Isle of Sheppey is located in the Thames Estuary, 53 miles east of London. As well as laying claim to being the birthplace of aviation in the UK, the Isle of Sheppey marks the entrance to the strategic ports of the Medway, is partly below sea level, home to one of the largest car and soft fruit import businesses in the UK, has three prisons, numerous caravan parks, two cuspate forelands, and the longest running community radio station in the UK. With a landmass of 36 square miles and its highest point at 76m above sea level, it is characterised by low lying marshlands which provide home to a wide range of migratory birds as well as rich, fertile soil on the higher ground. It lies east of the Isle of Grain across the Medway channel, and to the north is bounded by the Thames Estuary with its sandbanks, wind farms, the famous Maunsel forts, and the view towards Southend on Sea.
The population of 40,300 people is distributed between the main settlements of Queenborough, Sheerness, Minster, Warden and Leysdown on sea with some smaller outlying villages and farmsteads. The Island is part of the county of Kent and under the local juristiction of Swale borough council. The northern coast of the island is largely affected by coastal erosion. Such area currently has no defense against coastal erosion. As a result of ths policy of non-protection, many houses have been moved from their native location considered of high risk to a safer one in the centre of the island. The area highlighted in red in map on the right ( ig 7) was chosen as area of interest for the main building project.

1.2.3 Site history
The historical maps on this page illustrate how the chosen site has changed over time. A great amount of land has been lost as a result of coastal erosion. The erosion rate is different for various areas of the northern coasts. In many points of the island more than 150 m of land have been lost from 1896 to current days. The mean low water level has also dramatically regressed by more than 150m of average (more than 300m in some points). This has an enormous effect on local communities. Many houses that were located in proximity of the maritime cliff have been relocated towards the centre of the island to a more secure location. Caravan sites that extend just before the cliff have been are still are damaged by this natural phenomena.

Context and introduction 1.2 The site
The map on the left (1896-2015) illustrates the process of erosion of the northern cliff of the island over a period of almost 120 years, more precisely from 1896 to late 2015. The analysis of coast line, cliff edge and mean low water level of four historical maps (1896, 1908, 1939 and 1964, on the left) is here compared with the current morphology of the island.
How is this relevant to my project? The aim of this drawing is to demonstrate the rate of cliff erosion and resulting changes in topography of the island. Such study will allow me to speculate on future scenarios and effects on the communities and residents in proximity of the northern coast of the island.

15
1.2.4 Site photographs
During my site visit I came across many warning signs located in the proximity of the cliff. Some of these looked very aged, con irming coastal erosion has been affecting the northern cliff of the island by very long time. Most signs found on site advise not to proceed further towards the cliff due to unstable soil and dangerous ground condition. While I gained access to the site through the beach (picture 1 on the next page), it was practically impossible to go down the cliff in proximity of these signs due to very steep slopes and dense vegetation.

1.2.6 Bathymetric chart - Sea depth
The map on the left is known as bathymetric chart, a technical term used to indicate sea depth. The sea depth of the coastal zone where the proposal is located is about 5m. How is this relevant to my project? Sea depth, in relation to water level, has been a key factor that determined the height of the columns that support the research facility lifting if above high water level at all times.

Context and introduction 1.2 The site
1.2.7 Sandbanks
The proposal is intentionally located far from sandbanks. Sandbanks can contribute to the creation of very tall waves (wave shoaling, ig.15), which can be particularly treacherous for boats. How is this relevant to my project? Locating the proposal within the sandbanks would have made access to the facility by boat more dif icult and risky. This could potentially cut the supply of all the material and equipment delivered to the facility by boat.

21
1.2.8 Geology and habitats
The map on the left illustrates the geology of the chosen site. As I experienced during my site visit, the cliff is mainly muddy, making access to the site very dif icult. How is this relevant to my project? The ground condition is one of the factors that majorly affects coastal erosion. Both design and construction team need a thorough understanding of the site geology. Geology and habitats (including plants, animals) will be also key factors to bare in mind before, during and after the construction phase of the proposal.

1.2.9 Wind rose diagram
The diagram on the left is a wind rose diagram and it indicates that the prevailing wind on site is coming from South West. Winds coming from North East are also common. How is this relevant to my project? Wind is one of the factors that generates waves, and as such is one of the elements being constantly monitored in the research facility.

How is this relevant to my project? My building faces predominantly east. The buildingâ&#x20AC;&#x2122;s facade is essentially a curtain wall which faces east and west, letting light in throughout most of the day (see lighting study at page xx). The renderings on the next page constitute a 3d investigation on shadow casting on the chosen site (located in the middle of the renderings) at selected moments of the current calendar year.

The calendar present in this page aim to represent graphically the tide tables (calendar year 2015) at the location of Minster on Sea, on the Isle of Sheppey. The charts llustrate the variation in the range of the tides during each month of the past year, day by day, in relation to the gravitational forces of the Moon and Sun. How is this relevant to my project? The information obtained from such study has been used to actively in luence the design proposal and the position of the research facility in relation to the varying sea conditions.

The series of graphs present on this page gives an overview of the climate on the Isle of Sheppey in 2015. The average temperature is set on 12.2°C, with an average temperature range between day and night of 6°C. How is this relevant to my project? Understanding the climate conditions for the chosen site will help determine some of the environmental strategies for the proposed research facility (e.g. glazing, heating, ventilation etc.).

1.3 The proposal
1.3.1 Overview
The proposal is essentially a composition of the following elements: a staircase, a pier, a main research facility and a secondary one (secondary in size, but not less important)(see ig. 22).
1. The staircase The staircase has the function of creating a new access to the site, linking the top of the cliff with the pier which will be built at the bottom. The staircase is accessible by the public, and at about half way, it provides private access to the secondary research facility located on the slope. 2. The secondary research facility The secondary research facility is relatively small in size. It hosts a dry lab for the analysis of sediments and rocks, and a computer lab. Right next to the facility is located a small radio tower
28
which collects weather data and send it directly to the computer lab where it is processed. 3. The pier The concrete pier links the main research facility to the mainland. The pier is raised about 7m from the seabed and is about 200m long. This sensibily reduces risk of the pier being submerged by waves although such event is likely to take place in case of storm surges. 4. The main research facility The core of the proposal is the research centre located at the end of the pier structure. Here most of the research is carried out, including tests which involve the use of arti icial waves created in one the two lab the centre houses.

1.3.3 Precedents
The Field Research Facility (FRF) is a coastal observatory located near the town of Duck, in North Carolina. The FRF was completed in 1977 and took almost two years to build. The facility consists of two major buildings, a 560m long pier and a variety of specialized vehicles which help researchers recording the changes in the environment. The irst of the two buildings is the main laboratory which houses the main computer system, maintenance equipment and of ices. The second building consists of a conference room with a view on the ocean, a workshop and a technical library. Various instruments at the facility constantly record and gather data on the changing of winds, currents, tides and waves.

Some of these include: - a Costal LIDAR and Radar Imaging System mainly used for scanning activity; - a series of amphibious vehicles used to deploy instruments and sensor; - a video and radio tower which collects data in real time. I used the FRF as a reference for the organization of spaces and needs of researchers in terms of spaces. I also gave me a better idea of the different number of instruments and research methods which are necessary to conduct research activity in a very dynamic environment. This proved how the amphibious vehicle designed for my ‘Personal adaptor’ project would well suit the research activity of the proposed facility.

Context and introduction 1.3 The proposal
The Marine Building ( ig. 26) is a recent addition to the university of Plymouth, UK. It houses the Coastal Ocean and Sediment Transport (COAST) laboratories, the Marine Navigation Centre and the Marine Innovation Centre (plymouth.ac.uk, 2012). The Marine building was completed in 2012 with a cost of £19m. The COAST laboratory ‘provides physical model testing with combined waves, currents and wind, offered at scales appropriate for device testing, array testing, environmental modelling and coastal engineering’ (Plymouth, 2012). This is achieved with the use of a unique facility known as ‘wave basin’ ( ig. 28) which is able to simulate a marine environment by generating arti icial waves, currents and strong winds. The wave basin is a huge tank which measures 35m in lenght and about 15 in width, for a total
Figure 26: Exterior of the Marine Building
of about 500 sqm. The COAST laboratory also houses two wave lumes ( ig. 27), generally use for studies on sediments, tidal energy as well as currents.
Project name: Marine Building Type of building: Research facility, education Location: Plymouth, United Kingdom Year of completion: 2012 Cost of construction: £19m
The Marine Building is one of the world’s most renowned laboratories of coastal engineering and is the proof that expensive technology is required to gain a deep understanding of natural phenomena.
I used it as a reference for: spaces organization, research instruments
Similarly to the Marine Building, the proposed research facility houses a 400 sqm wave basin and a 25m long wave lume, instruments which can be regarded as essential tools to conduct indepth research related to coastal erosion and its causes.

1.3.4 The client
The client of the project is the Environment Agency. The Environment Agency is a public body established in 1996 and sponsored by the United Kingdom governmentâ&#x20AC;&#x2122;s Department for Environment, Food and Rural Affairs (DEFRA). The Environment Agency is responsible for the protection of the environment within Englandâ&#x20AC;&#x2122;s territory. More speci ically to this project, within many of its tasks the Environment Agency is responsible for: - conservation and ecology: - managing the risk of looding abd coastal erosion The majority of funding for lood and coastal erosion management is through grants from Defra to the Environment Agency (EA).
34
In 2010 the Environment Agency set up the RFCCs (Regional Flood and Coastal Committees). The RFCCs help the Environment Agency by: - ensuring there are coherent plans for identifying, communicating and managing lood and coastal erosion risks across catchments and shorelines; - encouraging ef icient, targeted and risk-based investment in lood and coastal erosion risk management that represents value for money and bene its local communities; - providing a link between the Environment Agency, LLFAs, other risk management authorities, and other relevant bodies to build understanding of lood and coastal erosion risks in its area.

1.3.6 Cost, Time and Quality
What are the priorities of the Environment Agency for the realization of the research centre? How will this have an effect on costs, time and quality? Considering the funding for the project comes through the government (see section 1.4.3: funding), the Environment Agency (EA) will aim to keep the costs down. However due to the scienti ic nature of the proposal there can be no compromise in terms of quality. As a result time for completion of the proposal may be of secondary importance.
Procurement route selection The EA appoints the contractor since the early stages of the process, adapting a TwoStages Tendering for Design-and-Build-based procurement.
36
Considering the complexity of design and groundworks required, and the fabrication of bespoke concrete elements, two-stages tendering is, in theory, well suited for designand-build procurement. It in fact allows collaboration between the contractor and the clientâ&#x20AC;&#x2122;s designers, giving the contractor the opportunity to contribute to the design process on buildability, sequencing and so on (building. co.uk, 2006). This could also potentially enable to commence site works earlier on in the process.

1.3.8 RIBA Plan of Work
0. Strategic Definition: The Environment Agency identifies the project’s scope and some of the project requirements. Similar project are evaluated. The client begins to consider the assembling of the project team. 1. Preparation and Brief: The client develops an initial project brief, outlining the project objectives, aspiration and budget. Feasibility studies are undertaken at this stage. The project team is assembled. 2. Concept Design: The project team produces a first outline proposal, illlustrating some of the project strategies (environmental and structural). The initial brief is reviewed and a final project brief is issued. 3. Developed Design: At this stage different iterations of the design may be produced and different tools may be used. Some of the subcontractors (e.g. concrete specialists) may intervene at this stage in order to produce a more robust developed design. 4. Technical Design: Technical drawings will be produced at this stage. At the end of this stage the work of the design team will be completed, however the designers remain avaiable for design queries that may arise during Stage 5. 5. Construction: Construction works begin on site and will last for approximately 1 year and a half. The safety of the workers on site needs to be guaranteed; the contractor work out with the designers any possible change in design that may be needed due to site-related issues. 6. Handover and Close Out: Construction works end and the building is inspected. Keys are then issued to the client. 7. In Use: The building finally opens to the public and research activity begins.

1.3.9 Benchmarking
Considering use and function of the building, I used the Field Research Facility as a benchmark to estimate the total cost of my proposal. Given the total cost of £4.5m (for both buildings and pier), I divided it for the loor area of 480sqm, obtaining a cost of £9300/sqm. I then mutiplied this igure for the loor area of my building and obtained a total of £13m. Field Research Facility cost/sqm £4,500,000 / 480sqm= £9300/sqm Proposed research facility cost £9300/sqm * 1400sqm= £13,000,000

1.4 Planning
1.4.1 A site of special scientiϔic interest
In 1998 the site has been designated as a site of ‘Special Scienti ic Interest’ (SSSI) by Natural England’s, a public body of the UK government responsible for ensuring that England’s natural environment is protected and improved. The condition of site has been classi ied by Natural England as ‘favourable‘, meaning that ‘habitats and features are in a healthy state and are being conserved by appropriate management’ (Gov.uk, 2016). Reasons for designating the site of ‘Sheppey Cliffs and Foreshore’ as SSSI are explained in a document available on Natural England website, and are as follow: ‘This classic coastal section is one of the best known Palaeogene sites in Britain having been the focus of scientiϔic study since the eighteenth century. The cliff and foreshore section between Warden and Minster comprise Eocene London Clay, capped by Pleistocene sediments except between East End and Cliff Farm where the cliff intersects an outlier of the Eocene Virginia Water Formation. This is the only extant section of the upper part of the London Clay and is
40
geographically the most extensive section of this Formation in Britain.’ ‘Present day active processes have also been studied in considerable detail. At Warden Point, and to its west, a series of impressive, deep-seated, rotational landslips (bench shaped in plan) occur in the London Clay. Characteristically, each slip extends along the coast for distances between four and eight times the cliff height. The backtilted blocks produced by failure are broken down by shallow slides and mudϔlows, the debris being removed by marine erosion. This in turn results in a progressive steepening of the cliff, and thus in further landslipping. This is the best locality in Britain to observe the cycle of rotational landslip typical of soft coasts.’

1.4.3 Funding
The project is funded by Department for Environment, Food and Rural Affairs (Defra). Defra gives the majority of its loods funding (ÂŁ661.4m) to the EA as Grant-in-Aid, which is the mechanism for inancing a Non-Departmental Public Body such as EA. The EA spends this funding directly on Flood and Coast Erosion Risk Management (FCERM). Defra is committed to a six-year programme of capital investment to improve defences up to up to 2021, of ÂŁ2.3bn. 2015/16 is the irst year of this (see table below).

2.1.3 Material choices
Both the pier and the building structure will be built using concrete. Concrete is a relatively inexpensive material and due to its workability, strenght and durability represents a valid alternative to steel, especially in marine environment.
Figure 33: Detail of timber-shuttered in-situ concrete
Concrete works very well in compression but not in tension. This is the reason why reinforcement steel bars are often placed within the formwork, providing good tensile strenght. In relation to the structure I designed, reinforced concrete will need to be used, providing good resistance to the bending moments of the slanted columns. The concrete used on site will be a mixture of Portland cement, water and aggregates (sand and small stones). High-strenght concrete will be used for the construction of the columns of the building. This type of concrete is characterized by a ratio water/aggregates lower than 0.35,
Figure 34: Example of timber formwork for walls
50
and has greater compressive strenght than regular concrete (5000ps vs 1500psi). The images on the next page are buildings I looked at when designing the buildingâ&#x20AC;&#x2122;s structure. All these references (see pictures for projectsâ&#x20AC;&#x2122; names and architects) share the use of concrete as construction material and, although fabrication methods vary, there are evident similarieties between them in terms of structure and geometry.

2.1.4 Heating, cooling and ventilation
The building makes use of under loor heating to regulate the temperature of most of the rooms. Vents located in different zones of the building let fresh air in. Fresh air is then heated up thanks to the under loor heating system and tends to rise towards the ceiling as it becomes lighter. Warm air slowly loses its energy and therefore drops again towards the loor surface, where is then heated up again in a continuous cycle. This cycle allows great savings in terms of energy and power consumption. The use of under loor heating is preferred to radiators due to their innef iciency to heat spaces uniformly. The use of radiators would in fact create cold spots in most of the rooms.

The area of focus for this report is illustrated in the drawing on the left page. This fragment of the building is particularly important as it hosts the entrance of the building (both for public and users), and a 400sqm wave basin, main instrument of research and testing in the building. The entrance of the building is essentially a steel bridge which spans between two concrete beams, and is anchored to the concrete columns which penetrates the buildingâ&#x20AC;&#x2122;s skin through cables. A suspended walkway around the wave basin allows the laboratory users to better observe and record ongoing tests and experiments. By locating the entrance above the wave basin, visitors and users are able to look down the (otherwise private) wave basin to observe ongoing activity and both look out the building towards Sheerness through a curtain wall which constitutes the buildingâ&#x20AC;&#x2122;s facade ( ig. 39).

2.2.2 Considerations about construction
What are the main issues related to underwater construction and how are these resolved? The main issue related to underwater construction is keeping the water outside at the times of constructing the building’s foundations. This is resolved by placing on site a temporary structure called caisson or cofferdam ( ig. 42) which keeps the water outside of its perimeter, allowing water within it to be pumped out. The use of these temporary structures allows the creation of a dry work environment, considered a key factor for the construction of the building’s foundations. Another issue is related to the use of construction vehicles on water. This is easily resolved through the installation of cranes and other major vehicles onto barges ( ig. 40-41). Bridges and pier structures are built in similar ways.
Figure 41: Example of pier construction using ϔloating cranes.
56
In terms of storaging construction materials, the coast of the island offers no secure location for the storage of these. For this reason barges loaded with construction materials will need to be moored offshore, at a close distance to the construction site.

Integrated technology 2.2 The fragment
2.2.3 Tranportation and access to the site
How will construction material be transported on site at the time of construction? Due to its location at the bottom of a cliff, the site is not easily accessible by land. Therefore most construction material will need to be transported on site by boat. In this sense the Isle of Sheppey is not very far from London, from where most of the construction materials will be tranported from. The Thames river becomes the main that will be used to transport materials on site. A journey through the Thames to the Isle of Sheppey will take approximately x hours, depending on speed and other factors. The map on the left simulates the naval route followed by boats loaded of concrete (supplied by Euromix concrete in North Greenwich) through the river Thames down to the site on the Isle of Sheppey.

2.2.4 Construction sequence
58
STAGE 01 A sheet pile cofferdam is placed on the site where the building will be built. The caisson is transported on site by boat.
STAGE 02 Water is pumped out from the cofferdam, keeping the internal environment dry. This enable the start of ground works for the buildingâ&#x20AC;&#x2122;s foundations.
STAGE 03 Pile foundations are cast in-situ. The foundation will be about 15 to 20 meters deep into the ground.
STAGE 04 The primary structure is built. Concrete columns and beams are cast in-situ using a timber formwork. Reinforced concrete is used for the columns.
STAGE 05 Between stage 04 and 05 the cofferdam is removed. Floor slabs are cast in-situ, providing a first surface for workers to walk on.
STAGE 06 The secondary structure is added. Steel beams provide support for the walkway and buildingâ&#x20AC;&#x2122;s entrance. Beams that support the roof are also added.
Integrated technology 2.2 The fragment
STAGE 07 The roof is placed onto a series of beams. This allows for a better working environment, protecting workers from rain.
STAGE 08 The walls are constructed. From this stage onward services will be gradually added.
STAGE 09 Insulation is added to both walls and floors. The roof has been removed from the drawing to facilitate its reading.
STAGE 10 All the internal walls are built at this stage, including the wave basin control room shown in the drawing above.
STAGE 11 The curtain wall is built. Glass panels are added to the entrance-bridge. The front facade has been removed from the drawing to facilitate its reading.
STAGE 12 All the finishes are added in this last stage. The wave basin is installed. The building is completed and ready to open after inspection.

2.2.5 Physical model
60
Integrated technology 2.2 The fragment
The physical model I realized is a structural model of the fragment studied in more depth in these pages. The model is essentially made out of 6 different components: - a solid base of 3mm white acrylic board; - a hollow base of 3mm white acrylic board which is glued on top of the solid base; - 2x 3d printed support which it within the hollow base; - 7x 3d printed columns (in white) which it into the 3d printed support; the columns constitute the primary structure of my building; - a laser-cut walkway (in light brown) which its within the columns; - a laser-cut bridge (in dark brown) which represents the entrance of my building. A 7th element, the roof, may be added to the model later on this year. Due to the columns tapering toward one end, 3d print resulted being the most accurate technique for the reproduction of this model. Using the more traditional (and inexpensive) laser-cutting technique would have resulted in the columns being cut lat, with equal diameter.

The building has got a curved concave roof which emphasizes its geometry even more. The concave roof was inspired by the beautiful in-situ cast concrete roof of the Chiesa dellâ&#x20AC;&#x2122;autostrada del sole ( ig. 44 below and ig. 35 at page 51). Although the roof of the proposed building is not made of concrete, it resembles the one of the aforementioned church in its shape and structural principles.

The roof of the building is a low pitching roof with curves and tapers. This type of system is particularly ef icient and well suit curved roofs, both concave and convex. Note: The cladding of the buildingâ&#x20AC;&#x2122;s roof would actually need to run perpendicularly to the beams rather than being parallel to them. This would allow rainwater to low along the roof rather than being stuck between the cladding panels. This technical issue has been acknowledged when all drawings were already inalized and not enough time was left to adjust them.
