THE DESIGN OF A PUBLIC SWIMMING POOL FOR PRETORIA CENTRAL by JUAN PIERRE MYBURGH

Submitted in partial fulfilment of the requirements for the degree MAGISTER TECHNOLOGIAE: ARCHITECTURE (APPLIED DESIGN) In the Department of Architecture FACULTY OF ENGINEERING TSHWANE UNIVERSITY OF TECHNOLOGY Supervisor: Prof. J. Laubscher November 2014

I hereby declare that the dissertation submitted for the M Tech Architecture: Professional, at Tshwane University of Technology, is my own original work and has not been submitted to any other institution. All quoted texts are indicated and acknowledged by means of a comprehensive list of references.

abstract // The aim of the thesis is to design a public swimming pool that re-connects street and river within a particular urban condition. The ground plane of the selected site is manipulated to facilitate a physical and visual connection with the river. Wetlands form part of the landscape surrounding the facility and on urban scale to assist in the cleaning and re-use of water from the canal.

The proposal includes two pools accommodating different human interactions with water. The pool lanes serve as form generator and the subsequent design employing repetition and rhythm extensively.

The transitions between wet and dry, land and water were explored extensively during the design process.

The built form mostly serves a supporting function to the water bodies. The buildings are designed as a transitional space between inside and outside.

The site was carefully selected based on the mix of current educational facilities, offices and residential accommodation.

SECTION CONCEPTUAL SKETCH Image 7 // By author, 2014

The site was developed using various layers namely: Private swimming, public swimming, spill out spaces, as well as spectator and passer-by contact. The transition from wet to dry influences the barrier between land and water.

It is envisioned that the proposal will form part of the larger Tshwane 2055 framework aiming to revitalize the Pretoria CBD, although canalized, the Aapies River forms an important life giving artery adjacent to the Nelson Mandela Corridor. As part of the design proposal it is envisioned that the canal be used as a floating walkway in future with follies linking specific sites and the river at strategic points.

The proposed lap pool adheres to international standards. Both the pools step towards the canal, providing a different spatial and sensory experience.

The design may serve as a guideline for future proposals along the canal. URBAN SWIMMING must inspire social growth and promote swimming as both a sport and a recreational activity.

chapter 1 // introduce “Just three months out of every twelve we pass, In merry-makings, then we go to grass, And work the other nine! On pleasure bent We anxiously look out for some event – A wedding, or a christening, a race, A raffle, picnic, or a paper-chase, A birthday, or a ball, or a bazaar Sets all the town off with one big ‘hurrah’” Albert Brodrick (1955: 37)

1.1 introduction The fear of swimming and ultimately of drowning is a paradox that disappears when young children are encouraged to interact with water and take up swimming.

According to the professional swimming coach, Chris Zungu (2014), water exposure is the main remedy to combat the drownings that SA has experienced in the past 20 odd years.

Although canalized and restricted from its natural flow, the Aapies River is the largest natural element in Pretoria Central Business District (CBD). Submerged under the city scape, it is unattended and neglected.

The City of Tshwane Master Plan for 2055 states that the Pretoria CBD has an uninviting physical appearance with underachieving relaxation activities. According to the City of Tshwane (2012: 7), inner city living is less desirable due to the ill-functioning business, property and leisure market. The CBD, while currently being gentrified by various residential and commercial projects, does not expose dwellers to a consequent amount of stimulation, pleasure or excitement. Patrick mentions that the varying zones need to overlap to prevent unsustainable patterns of movement (2008:8). The architect Theo Crosby, mentions that a city made for access is made for success. Furthermore, he believes cities must be grown on a basis of social interaction and exchange. The city should create new centers so they can grow into elements of a city (Crosby, 1965).

Residents living within the city need to leave the CBD in search of recreation activities.

For example, the closest public swimming pool to the city center is 2,7km away – a 35 minute walk.

INACTIVE FURROW SYSTEM OF PRETORIA Image 10 - 12 // By author, 2014

1.2 pretoria history The perennial springs at Fountains Valley feed into the Aapies River. Before its canalization, the river played a predominant role in the settlement. The annual rainstorms would swell the river over its normal boundaries.

The first bridge over the Aapies River was constructed in 1894. The Lion Bridge connected the eastern and western side of Pretoria via Stanza Bopape Street (Church Street). For many years the bridge was surrounded by open grass fields. Jacob Hendrik Pierneef, the renowned South African landscape artist, mentioned how he and his friends went swimming in the dam-like areas along the river. In 1909, three people drowned, which led to the river being canalized (Meiring, 1955: 152).

Although the Aapies River Canal has become a void space in the city, it has acted as an important infrastructural piece to shape the spatial framework of Pretoria.

1.3 pretoria water After the establishment of Pretoria in 1855, for nearly 75 years, the two springs at Fountains Valley supplied the settlement with fresh water. Currently, the upper fountain provides approximately 24 million liters of water per day while the lower fountain discharges approximately 18 million liters per day. Pretoria uses approximately 270 000 million liters per year, supplied via the Rietvlei Dam, Rand Water, boreholes in the surrounding vicinity and Fountains Valley. Currently the water from the two fountains are pumped to a mixing chamber, with the excess being fed back into the Aapies River.

Pretoria used a gravity based furrow system transporting water from the two fountains to the Sammy Marks Fountain at Church Square. From here it flowed back into the Aapies River. Over time, improper maintenance resulted in the decay of the furrows (Dippenaar, 2013). Evidence of this system is visible as a memorial on the edge of Stanza Bopape Street (Church Street), north of the State Theatre.

The canal could be transformed into a ‘green lung’, a breathing space. Its success is dependent on the quality of the water and the fluctuating level of the water, but it holds unrealized potential as an artificial albeit ‘natural’ river that is accessible to the city dwellers.

1.4 the history of swimming

GAUTENG SWIMMNIG LESSONS Image 14 // Diseko, 2012

During the Olympic Games of 1896, swimming became an official sport. Currently, the Olympic Games host 32 swimming events: 16 for men and 16 for women. The National Association for Swimming in South Africa was established in 1899. In 1908, the South African Amateurs Swimming Union was formed and it was estimated that approximately 15 clubs were established by 1909. What followed were years of controversy and separation between culturally different swimmers. In 1994, the federation was renamed, Swimming South Africa (SSA). According to the Chairperson of SSA, the transformation of swimming in South Africa is a priority. The immediate challenge is to supply disadvantaged communities with swimming facilities which have partially been met with providing Porta Pools (Parsons, 2006 cited in Thipe, 2007:16).

1.5 african championship records South African swimmers have obtained the most records at the African Swimming Championships. Out of the 20 events of 50m, 100m, 200m, 400m, 800m, 1500m single, and 400m and 800m relay, ranging over 5 non-consecutive years, South Africa holds 15 records in the Men’s Events and 13 records in the Women’s Events. While the South African team sets a strong example for Africa, it remains very important to continue to improve on our swimming skills (SwimmingWORLDmagazine, 2013, Appendix A).

1.6 rationale  The city framework is upgrading more rapidly with residential and commercial units, than with social and public spaces.  The Tshwane 2055 Proposal includes a ‘Musanda’ walkway that would sit around the Pretoria CBD.  During the rainy season the Aapies River water level fluctuates unexpectedly and suddenly.

URBAN CONCEPT // CAUSE l CAUSALITY CAUSAILTY

Convert the canal back into a natural river.

Controlling the fluctuating level of the river was the major contributing factor for transforming the natural flow of the Aapies River into a concrete canal. It could be argued that the solution led to the forming of a void space. As time passed it needed a functional solution. The cause, in this sense, refers to the river flooding on a frequent basis. Causality is associated with the canalization of the river. The two were intertwined as an intervention. Causality is often the result of addressing an identified problem. The subsequent result or ‘cause‘ is the void space within the city.

The design proposal will act as the new causality. Stated differently, every action leads to a reaction. A new proposal for a problem will include another problem - an endless loop.

The canal was purely built for an infrastructural purpose; namely to prevent flooding and possible drowning. Over time, the absence of interaction with the river has created a void space within the city. Therefore, the canalization of the river influenced the subsequent development of the city. The canalization of the Aapies River led to its interaction with the city fading over time. The proposal is to reconnect the canal and the surrounding spaces, forming a new activity node.

WHEN THE WATER LEVEL IS LOW

The air pool is a threshold space between dry and wet. The swimming pool acts as a container for water while the surrounding built or natural edges surrounding the pool above ground, contains the air pool. The profile of the container, the surrounding edges, and the roof plane influences the size of the air pool. It is the negative space above the water and any addition or subtraction of water from the pool that results in a changing air pool.

Similarly, the river functions as a water container. As the water level of the river alternates, the surrounding landscape responds. The so-called air pool is influenced by the new profile changes to the canal. The threshold space is explored to form part of the preparation process that swimmers routinely undergo when entering or exiting the water body. In the project this transition is interpreted as an inside-outside space distinguishing between dry and wet.

WHEN THE WATER LEVEL IS HIGH

BUILDING CONCEPT // OPPOSITE LANES A swimming pool could be described as a water container with different activity nodes. Some nodes allow for interaction and socializing, while others provide space for training. It could be a place of interaction, but also of isolation and preparation.

Similarly, the building will have features to separate certain areas, but still allow a certain level of interaction.

Within the building, walking along the movement routes help prepare the users for the ritual of swimming. The design accommodates different views to the outside, as well as varying spaces inside the building. The change rooms function as in-between space for inside and outside.

FORM & SPACE “We put thirty spokes together and call it a wheel; But it is on the space where there is nothing that the utility of the wheel depends.

We turn clay to make a vessel; But it is on the space where there is nothing that the utility of the vessel depends.

We pierce doors and windows to make a house; and it is in these spaces where there is nothing that the utility of the house depends.

Therefore, just as we take advantage of what is, we should recognize the utility of what is not.”

The design aims to reveal the hidden potential of the canal. The canal is unknown and therefore holds new experiences for city dwellers.

2.1 issues of concern SOCIAL SPACES OF PRETORIA According to Soichiro Fukutake (2011:26): “City people strive to attain happiness in the name of ‘self-actualization,’ but they are ultimately concerned only with their own happiness, and in competing to find it they become fraught with frustration and worry.

This is because human beings can never be truly happy unless they are part of a happy community.”

The success of any city is dependent on a mixture of residential, commercial and social spaces and the established links between these areas. Each city dweller requires a set of stimulants - if these spaces are offered and accessible, the city dwellers could embrace the city as their ‘outside room’.

LINKING NODES FOR ACCESSIBILITY. Image 21 // By author, 2014

“OH! THE DAYS GONE BY …Oh! the days gone by, when our love was warm, When we met at the “Fountains”, in pic-nic form, When we all brought turkeys and fowls and ham, And liquor and tarts and imported jam, And we danced and sang till the echoes cried, From the cave’s dark depths, on the steep hill’s side, And with many a laugh and clang of hoof We all drove home through the star-lit kloof…”

Albert Brodrick (1955: 29) The Fountains Valley was once a space of regular gatherings. Today, this green space is limited to vehicles which may only enter at one main entrance. As an enclosed green space, it still attracts visitors and cycling enthusiasts. However, the dominant highways surrounding the northern edge of the Fountains Valley limit its connection to the city. The design proposal could link the Fountains Valley to the Pretoria CBD to the Pretoria Zoo.

31 chapter 2 - negative space

According to Mr. G. Jansen van Vuuren, Chief Engineer for Integrated Storm Water Planning at the Tshwane Roads and Transport Department (2014, Appendix A), the canal needs to be made safer before people would be allowed direct access to it.

“The Metropolitan Spatial Planning [Department] is aware of the potential along the Aapies River and has introduced ‘Operation Reclaim of Inner City Regeneration’. The road works are not aimed at vehicles but to increase the pedestrian corridors and activities.”

If the canal is converted into a ‘Green Lung’ it could, within walking distance, serve the surrounding area. It would be able to link the proposed swimming pool to its neighboring sites.

CHALLENGES OF THE CANAL Quality of the canal water General water figures for South Africa: (WRC, n.d.)

Each person needs 20L – 45L of water for cooking, cleaning and drinking per day.

Due to urban sprawl and agriculture, 50% of wetlands have been lost.

The average rainfall annually is 500mm.

1,3 million ha. of land are irrigated.

RIVER USERS Image 22 // By author, 2013

Mr. G. Jansen van Vuuren (2014) states that the water quality of the Aapies River is problematic, although it is better than any other nearby areas. The Aapies River Canal is not connected to any sewer lines or polluted by industrial dumping, but businesses in the Pretoria CBD frequently dump illegal waste water and solid materials into the storm water system that ends in the canal. The main concern is that the pipes are not designed to carry the capacity of waste water and storm water. Furthermore, he acknowledges that a main sewerage line that runs underneath the canal received maintenance when the sewer water was found leaking into the canal. “We have industries around the canal that have taken responsibility for the canal as it will be to their advantage.”

THE NECESSITY FOR DRINKING WATER Image 23 // By author, 2014

FLUCTUATING LEVEL OF THE CANAL AND ITS PROFILE The total collection area of the Aapies River Canal, before joining the Walkerspruit Canal, is approximately 45km2. After joining Walkerspruit Canal, the collection area is approximately 67km2. The flow rate in the canal averages at 5,5m3/s, in the more level and steeper areas it reaches a maximum speed of 12m3/s.

When initially designed, the canal had to accommodate the 1:50 year flood line.

Currently, the Water Act of 1998 stipulates the 1:100 year flood line as a requirement.

Within the Pretoria CBD area, only the Pretoria Zoo and old Berea Sport Club does not comply with the 1:100 year flood line.

Lined with a smooth concrete texture, the main purpose of the canal is to remove storm water quickly from the built fabric of the city (Jansen van Vuuren, 2014). The rate of water removal is directly associated with the area available for flow. When flooded, it becomes a dangerous area to access or escape from. Various factors influence the differences in water levels between a rainy day and a dry day. The profile of the canal facilitates limited interaction with the water. The built fabric is not orientated towards the canal; it has resultantly become a negative space used as a disposal area.

HERITAGE OF THE CANAL We have allowed time to pass. The city has layers filled with memory, some are visible and some will need new stories to store. At a certain point in the future some lost space will be rediscovered. One must be careful not to fill the wound too rapidly as it could erase a set of memories from the city. The plot of a project is key to making it more than a merging of private and public rooms (Ferguson, 2006).

In the CBD of Pretoria a specific resource remains overlooked. In its current condition, the Aapies River Canal acts as a divider.

The underside of the bridges show-case a different history. These often ignored physical structures could be activated as an additional urban layer, provided the design proposal responds successfully to issues such as controlling storm- and rainwater. The density of cities increasingly requires void spaces to become “breathing lungs�. Is it possible to convert the canal into a 21st century river? At the same time the bridges are protected by the Heritage Act and should be preserved.

The bridges are the element that binds Pretoria Central to Arcadia and Sunnyside. The design aims to bridge the Aapies River as an urban barrier in a contemporary manner accommodating both the river and the canal.

During site visits conducted by the author to various public pools in Pretoria, the lacking variety in shapes and sizes were noticed. As a result, their users changed the pools’ intended use. Consequently, lap pools are utilized as public pools with the result of pools becoming overcrowded and unsafe. This practice indicates a real-world need for recreational spaces that use water as an integral design component.

Table 3 indicates the calculation of lifeguards per swimming pool according to its size. If there is only a single lifeguard on duty, he/she should be capable of requesting assistance very quickly. As an alternative solution, certain training companies determine their lifeguards’ response time within their observation area and how quickly they can reach a distressed person.

Eye contact is made - The second “hello” commences; sharing laughs, culture, pain and history.

RAINFALL APPROACHING FROM THE SOUTH-WEST TO THE CBD. Image 30 // By author, 2014

In the South African Water Act of 1998, a wetland is described as: “Land which is transitional between terrestrial and aquatic systems where the water table is usually at or near the surface, or the land is periodically covered with shallow water, and which, in normal circumstances supports or would support vegetation typically adapted to life in saturated soil� (DWAF, 1998).

Generally speaking, a wetland is an area where the geology or topography of the catchment can obstruct or limit the flow of water. The water plants can change the hydrology and soil characteristics by creating organic matter and further retarding the water flow.

A wetland both retards the water velocity and acts as purifying system. Because the wetland can slow the water movement over a widespread area, pollutants are allowed to drop and be captured by the soil and plants. The artificial organic pollutants are decomposed by the micro-organisms. The wetland provides habitat and safety for insects and fish, which to a certain point help clean the water too (Collins, 2005).

The wetland could actively sustain the site permanently. It would produce clean water from the canal; water would be circulated from the canal to the top of the site, from where it would filter down through the wetlands eventually finding its way back into the canal.

43 chapter 3 - research

3.2 wetlands // 24 hour activity

3.3 natural pools A natural pool is a chemical-free pool which is cleaned by a system of mixed water plants. The system consists of a variety of filtering layers. The area where the cleansing takes place is called the ‘Regeneration zone’. It is similar to a wetland, but the pool area is separated from the regen zone by a wall that ends a few centimeters below the water level. This allows the pool and Regeneration area to be seen as one seamless stretch. The regeneration zone consists of a substrate mixture of coarse bark and a deep layer of gravel. This creates a growing medium for the plants, a filter layer of varying aggregates and a habitable area for micro-organisms to consume any pollutants. The idea is that with a pump the water is continually circulated through the zones and skimmers.

The pool area still needs to be vacuumed on a regular basis. The plants need to be pruned, dead-headed and when the garden grows too dense it needs to be thinned out (Maritz, n.d. cited in: Celliers, 2014). For an effective circulation system, two pumps are added. The first circulates water through the regeneration zone to the bottom of the pool, and the second is on the water surface through a skimmer (Inspiration Green, n.d.).

For the natural cleaning method to be most effective the pool size needs to be equal to the regeneration zone. The water is less harmful to the skin because it has less chemicals in. The natural pool area will serve as a green spill-out space for the city.

SWIMMING EXPERIENCE Image 42 // By author, 2014

47 The straining impact on the body is minimal, but it provides an overall effective workout.

An ideal body maintenance; it keeps the body strong and flexible, and recovers from injury and illness quicker. It is ideal as a warm up and cool down session for other exercises. Swimming can decrease stress and increase alertness. Psychological benefits include sportsmanship and self-discipline as well as socialisation (Faulkner, 1996).

3.5 timekeeper guidelines 30 minutes before the race, the timekeeper needs to report to the referee. Equipment to bring along includes a stopwatch, pencil, note pad and a clipboard. The stopwatch time is a back-up time. The stopwatch is stopped at the point that any body part makes contact with the finish wall or passes the finish line. For championships, the Automatic Officiating Equipment (AOE) is used; it is electronically connected to the start devices.

However, in case of a malfunction the stopwatch time is used (Amateur Swimming Association of Jamaica, n.d.).

chapter 4 // case studies and precedents “To understand water in architecture, we need to understand the architecture of water.” (Whelchel & Donovan, 1994: 15) Growing up, the Boksburg Indoor Pool area remains a breathable, overpowering and beautiful volume. With steps cascading downward the air pool becomes evident.

A deep breath and… silence. The pool is an exploration of personal thoughts and relaxation. The individual can leave the pool area mentally and physically refreshed.

The large volume is still filled with silence.

4.1 case studies OTHER PUBLIC SWIMMING POOLS IN PRETORIA As a result of the analysis, it was concluded that the swimming pools in Pretoria are mainly located near single-storey residential areas. The majority of pools are not heated and are therefore inactive in winter. The pools mainly provide one type of pool function. Although the pools share similar ‘pool characteristics’, the users have often adapted its interceded use.

These pool areas serve as a design platform for the proposed public pool. Over looked design aspects in the visited public pools are mostly context, and landscape. It is believed that the thoughtful layering of different uses and activities could result in yearround use.

51 Even though it is an olympic size swimming pool, its visitors use it as a public pool. It has a large green space where visitors usually relax and picnic. A gymnasium forms part of the auxiliary facilities.

The larger part of the site is available green space. The pool is still the largest attraction, but the safe and tree covered area supports the pool activities.

HILLCREST SWIMMING POOL // Corner Jan Shoba Road and Duxbury Street, HILLCREST The Hillcrest pool is surrounded by built fabric and it serves as a good example illustrating the principle of the so-called ‘air pool’. Hillcrest Swimming Pool is heated up to 26oC during the winter, allowing for year-round use and making it convenient for professional swimmers. When compared to the similar pools, Hillcrest doesn’t provide a green space near the pool area.

The singular entrance makes access difficult during peak hours. Currently, most swimming competitions in Pretoria are held at Hillcrest Pool.

Hillcrest expresses the desired ‘air pool‘ most effectively. Its close proximity positioning of structures surrounding the pool increase the ‘depth‘ of the ‘air pool‘.

THE CANAL The storm water systems of Pretoria Central, certain parts of Pretoria West and central Pretoria East drain into the Aapies River Canal. The pump station at Fountains Valley controls the source of the Aapies River. It still provides a quiet movement space for wildlife. According to the Water Institute of South Africa (eWISA, n.d.), the region receives brief but heavy rainfall during the period November to February. Along and within the canal the following flora is found: TREES // Umbrella Thorn Acacia (Vachellia Tortilis), White Stinkwood (Celtis Africana), South African Wild Pear (Dombeya Rotundifolia), Bushveld Cherry (Pappea Capensis), Weeping Wattle (Peltophorum Africanum), Silver Cluster-Leaf (Terminalia Sericea).

CITY FINGERS The canal has become a barrier between Pretoria Central, Sunnyside and Arcadia.

The roads and bridges are currently the strongest tie-backs. The ratio of bridges to the space between the bridges results in less available crossing points and more void space. Where green spaces and sidewalks are larger, a greater cross-pollination of activity is present.

UNDERNEATH THE BRIDGES “’Underneath’ is a powerful planning instrument, with no particular concern for spatial sequence or articulation.” (Ferguson, 2006) The bridges are worn by years of continuous use. From above, we have become oblivious of their importance for vehicular access. When the bridges are viewed from below, this altered perspective reveals its infrastructural beauty. The scale, monumentality and importance of this ‘connecting’ device becomes evident. The Lion Bridge for example, is a steel construction atop a crafted brick column, representing a particular technological approach. This ‘underside’, could be termed the sixth elevation. The sixth elevation becomes evident when a structure allows its exploration from underneath.

Walking along N. M. Drive:

7:19m

Pedestrians moving from north to south within the city are constantly interrupted by the short distances of city blocks. Walking along the Nelson Mandela Drive takes approximately 43.5% longer than walking the same distance in the canal. The canal has no obstructions for which one needs to wait, making the floating walkway a viable proposal.

The canal is a hidden and seamless walkway, a corridor that stretches from Fountains Valley to the Pretoria Zoo. An unexplored layer of the city where time can pass as the noise and street activity is not present. The canal and design proposal could act as a breathing space for when the city becomes too busy.

Some sidewalks are inefficiently narrow and pedestrian activity can be distributed more evenly along the Nelson Mandela Corridor. If the canal is converted into a contemporary natural river, it could be more enjoyable as a movement route.

The design proposal could act as a future guideline for new buildings next to the canal. The landform could increase the water cleaning capabilities. As indicated on the sketch it could link the schools in the surrounding area to the swimming pool, establishing the education hub.

THE WATER LEVEL OF THE CANAL To increase and control the water level in the canal, floating barriers could be installed at intervals in the canal. The hollow profiles are filled with air which makes them float and effectively temporary dam the canal. When the river starts to flood the air is allowed to escape and the barrier lowers and allows the canal to serve its purpose. When the level of the water rises, a signal will notify the users of the walkway.

The slanted canal edges will need vertical links at regular intervals that are positioned according to the maximum walking circle distance. The follies will include a rentable space and every second building could be a security point for the canal walkway. For safety purposes the water level in the canal is raised, the walkway raises and separates from the follies. The proposed walkway decreases the available flow area in the canal, which increases the depth of canal without increasing the amount of water that flows in the canal. The roof collects rainwater and solar panels generates electricity.

DERELICT “An idea that if ‘something’ is missing, it is also possible that ‘something’ leftover resides in the lack. Unobserved in a time of optimism, the ‘inhuman’ progression of techno-science erased social cooperation and community… The mechanism of hope is linked to that of realism. Once the proletarian social subject has greatly increased its penetration of the real, then we know that the revolution is possible.”

6.1 site selection The proposed site on Nelson Mandela Drive is zoned for public open space and business. Overlaying the urban analyses arrives at an open site that is quiet, but centered between larger activities. The site is located in the newly identified Nelson Mandela Student Urban Design Framework as a recreational node for Tshwane. (Mahne, 2010) Students at the SA College Private School (Grade 0-12) were asked and confirmed that the majority can swim, are interested in learning to swim and will enjoy an open park and pool area in close proximity to their school. SA College is located north of the chosen site and will become an intricate part of feeding the pool area with young swimmers. TUT Arts Campus and Arcadia Campus is within walking distance from SA College, which could help grow the popularity of swimming over the foreseeable future.

6.3 physical experience On site is a BMW motorcycle shop which is currently to let as well as an unmaintained Auto Body Mechanic’s building. The site is covered in heaps of soil and stone from the demolished building to prevent any activity on site, but people still use the heaps for safety, noise and wind protection. The northern strip of the site is used as taxi parking because of the tree line. The south-western corner has been transformed into a public seating space. The western strip has an informal walkway next to the canal and the gardens create a buffer zone next to the street.

6.4 site development According to Mr. Jansen Van Vuuren (2014): “They aim to apply a set of requirements to sites next to the canal. For example, the building design must not turn its back towards the canal, new building lines from the canal as existing buildings have mostly been built till against the canal, and between the building line and the water edge it will only allow gardening.�

The proposed design together with the new regulations will ensure future projects respond better to the canal edge. Its aim should be to prevent any negative space forming along the canal.

SITE PHOTO OF THE RUBBLE HEAPS Image 101 // By author, 2014

NEW STREET EDGE TYPOLOGY To escape from the street noise, instinctive-designers have created a walkway next to the canal rather than walking next to the road on the allocated walkway. The new walkway is separated from the road by a densely grown garden. At some instances the buffer becomes a green park for sleeping, sitting or playing.

The proposed idea is to enlarge the new found walkway. A multi-levelled set of walkways creates varying experiences of silence and movement.

MODEL EXPLORATION The landform exploration focused on hiding the buildings from the street edge as well as create a podium that slants towards the canal. This allows visitors to enjoy and view the canal proposal. The outer edge of the site is still focused on public interaction, especially for the neighboring schools close to the site. The design aims to create a positive space between the canal and the buildings.

7.2 a new canal profile Analyzing various canal profiles, selection is based on optimum visual and physical interaction with the canal and maximizing the volume of the canal. The proposed profile of the canal becomes the site profile as well.

If the canal edges become wetlands, the plants will delay the flow of water. The profile of the canal is enlarged so that when it floods there is more space for more water. The canal level is flooded at night to control access with the Venice floating wall.

EYE ACTIVITY ON THE CANAL

ALTERNATIVE BOUNDARY WALLS

The canal can become more visually available if the slope of the site concentrates eye activity on the canal. The site is slanted towards the canal as a sign of respect.

The boundary wall has a secondary purpose. If the buildings are tucked underneath the slope, it doesn’t take any green space away from the site.

7.3 plan development The selected section profile is further explored on floor plan. The site would be allocated to act as a gathering and public space. It will not necessarily link to an existing main movement route, but its location is well centered around city activities. The buildings and landform developed from a rigid grid in accordance with the city framework, but reached a more free-form approach in the end.

Superimposing various grids arrived at a certain spatial potential. The main aim of the site is to provide a green space for the city users.

7.4 section development The sections explore the pool position versus building position. The angled faรงade relates to the pool profile. Outside the building thin corridors create public and private movement routes. The terraces step down towards the center of the site to create a stronger connection to the canal. The vaulted roof provided a seamless line of materials across the swimming pool, against the walls and over the roof. The roof is extremely strong and provides a sensual experience of sound and texture within the building. Vault roofs are not new to Pretoria, for example the public bathrooms at the Union buildings allows light to filter.

119 FLOOR PLAN CONCEPTUAL MODEL

The outside walkway links the three buildings. It creates a split between a public green area and a more semi-public green space that faces the swimming pools and the canal. It is sunken into the ground to create a hidden ‘Boundary wall’.

The model explores the building’s connection to the swimming pool, as well as its connection to a temporary pool across the canal. The temporary pool is filled by the Aapies River and is open to the public, no entry fee is required.

Furthermore, the model illustrates various methods of how light can enter the building.

7.6 swimming pool ergonomics All swimming pool areas should be in accordance with FINA regulations.

Steps, ramps and handrails into the pool act as water-acclimatization areas.

The learner pool is preferred separate from the main pool for safety reasons.

An underwater window holds benefits for coaching and video capabilities.

1,8M DEPTH MIN.

CHANGING PROVISIONS // Dry and wet paths can be considered for the change rooms. Lockers, toilets and post-swimming showers need to be supplied. For easy movement and sense of programme, larger and color coated signs may be added. The pool orientation is not specific but can be determined by the best views, minimum shadows and setting the pool slightly off angle to prevent glare.

The focus is on swimming and gym enthusiasts to allow for movement between varying areas. The doors are controlled by membership cards and once-off payments at the reception. The building’s interior steps together with the landform and ends at a massage room and large window overlooking the canal. Next to the building a walkway leads to a temporary pool that is filled as the canal level changes. It provides a private cut-off area from the public pool.

The honeycomb wall is used in the bathrooms to filter the natural sunlight that enters through the frosted glass window. The outside walkway creates a physical barrier, but still allows a visual connection to the pools and the canal. It is punctured with views towards the swimming pools and seating space.

The honeycomb wall acts as a spatial divider between public and private movement areas. The skylights bring in early and late afternoon sunlight.

The interior skin of the roof becomes an attractive sixth elevation.

8.2 building 2 // restaurant building The building becomes the main link between the two swimming pools, it is therefore zoned as the most public building. It will accommodate noisy swimmers, restaurant goers and where necessary, quiet spaces are available. The first floor stretches across the Aapies River as a sculptural pedestrian bridge where access is controlled via a follie.

8.3 building 3 // lap pool building The building serves as the main entrance from the canal. From the southern side of the site this also becomes the main entrance. The movement in the building starts with a large entrance area, from this point to entering the pool area, the building focuses on preparing the swimmer. That is why the corridors become narrower and why the design explored the transition space between inside and outside. The staircases individually praises the swimmer before an event. The building ascends into the lobby area to create a back-up water barrier if the canal accidentally floods.

The section illustrates how the entrance walkway is visually connected to the swimming pool. The hot room is connected to the swimming pool via ramps. Cement brick honeycomb sunscreens allow visual connection between inside and outside. The hot room is the final destination after swimming. Warm air from the geothermal system dries swimmers afterwards and the building is ventilated through a custom louvre system at the top of the vault roof.

chapter 9 // technical resolution CONCRETE, BRICK AND WATER After nearly a century of water flow, the concrete surface has weathered to a smooth layer. The structure speaks of its own history, the erosion of time has discolored the concrete from a dark rough smooth concrete at the top, to a white shimmering rough textured finish at the bottom, illustrating the power of weathering. Considered, one of man’s strongest construction materials, the concrete has over time been punctured by nature. Slowly, it converts itself back into a natural river.

9.1 the red brick in the city “Sunlight occupies the space and is the instrument to investigate the inside/outside dialectic. Finding home as a “site construction“ naturally straddling the concurrent demands of architecture and landscape by reflecting both the rhythms of human occupation and the hydraulic engineering requirements defining its use.”

(Seakins, 2013:54)

chapter 9 - technical resolution

171

The city of Pretoria has a history of using red brick as a decorative and structural unit.

Norman Eaton succeeded in introducing the brick as an aesthetically pleasing element with varying patterns and color. For the proposed design the transition between inside and outside is one of the prominent focus areas of the design. The floors of the building can be laid with FBS Burgundy bricks to resemble a piece of Pretoria’s history. The change rooms are the main inside-outside transition space. The swimmers could be greeted with the warming red brick color before and after swimming. The change rooms have a raised floor that allows water to drain away and the floor to dry.

9.2 vault roofs // andre du preez Andre du Preez is an architect situated in Pretoria. Most of his projects include vault roof construction. During an interview construction methods, aesthetics and possible insulations were discussed. The least amount of stress is present at the top of the arch, whereas the sides tend to experience the most stress. The foot of the arch is continued two brick layers down to ensure the arch does not kick out. As an extra precaution a ‘kicker’ is added to support the arch.

Experienced builders are able to construct a vault without any form work and some builders use the form work mainly as a guiding tool. For the proposed design the vault roof will be built from cement bricks of varying textures and color.

chapter 9 - technical resolution

South Africa has a climate well-suited for daily summer swimming and some pools are available in the winter. As a general rule of thumb, an adequate water winter temperature for swimming is about 26oC (Zungu, 2014), which is easily manageable with basic heating equipment. However, as a sustainable approach geothermal heating systems may be considered. The most generic description is simply the movement of heat or cold from one point to another. The best known method is to lay a series of High Density Plastic Pipes beneath the surface of the earth and use the constant temperature that the soil radiates as an energy source. The air temperature is constantly fluctuating due to changing weather patterns, but the earth’s substrate layers stay constant for much longer. (SAAEA, 2010) The system can provide hot- or cold air and heated water. (Rainharvest, 2010)

chapter 10 // conclusion PARTING The aim of this dissertation is to provide a reaction to the current condition of the Aapies River canal. Every so often the canal floods and then the one and a half storey high canal becomes an essential space to continue the functionality of Pretoria. Descending into the quiet space dampens the surrounding noise, which resulted in the definition of an ‘Air pool’. Within the canal one feels disorientated within the city, but the spatial potential becomes evident. The water tries to flow naturally between the contours of the earth, but it is forced to follow the embankments of the man-made canal. The proposal should aim to return the site and canal to its natural state.

“It is said that good urbanism can be measured by the happiness of a city’s residents, for this is what draws people to urban areas and keeps them there.”

(Campbell, 2012). The proposed swimming pool addresses two focus areas, the canal and the social status of the city.

The landscape serves its purpose as a silent worker to restore the quality of the water. The design must therefore become a space of gathering and relaxation.

The daytime city dweller must become a part of the city. “...It’s our city, we are supposed to explore it...” (van der Berg, 2014).

LESS OF A VOID SPACE

chapter 12 - appendix

APPENDIX B // GEOTHERMAL HEATING South Africa has a well-suited climate for daily summer swimming, and even for the daring, some pools are available in the winter. As a general fixture, an adequate winter temperature for swimming water in winter is about 26oC (Zungu, 2014), which is easily manageable with basic heating methods. But as a sustainable approach, geothermal heating systems can be considered.

The most generic description is simply the movement of heat or cold from one point to another. The best known method is to lay as series of high density plastic pipes beneath the surface of the earth and use the constant temperature that the soil radiates as an energy source. The air temperature is always changing due to weather patterns, but the earthâ&#x20AC;&#x2122;s substrate layers stay constant for much longer. Therefore, during very cold periods the geothermal system can provide heat and opposite as well. A general accepted depth, but which is still dependant on the soil type and geological position on earth, is 1.5m minimum below ground. In South Africa the ground can vary between 16.5o C and 21o C. It is best to bury the pipes not underneath a building so that they are still accessible. (SAAEA, 2010) The pipes are filled with water and anti-freeze. The system can provide hot- or cold air and heated water. The pipes are called loops and can be laid in four different systems namely, horizontal loop, vertical loop, slinky loop or pond loop. The pipes are guaranteed to last up to 50 years. Two pipes are used as an inlet and outlet. To circulate the water it is connected to an electrical pump and a heat exchanger. â&#x20AC;&#x153;The heat from the fluid is transferred to a refrigerant with a low boiling point. This in turn causes the refrigerant to change to a gas, which is then compressed increasing its temperature.

The hot gases flow around a heat exchanger and transfer heat to the heating system.

As these gases cool they return to a liquid state and the whole process is repeated.â&#x20AC;?

In other words, due to compression of the gas at certain points in the pipe, the output temperature can be higher than the initial input temperature. (Rainharvest, 2010)

During its period of design, it was required to control the 1:50 year flood line.

Today, the Water Act requires flood lines of 1:100, which the canal is coincidently capable of containing. The only areas not capable of controlling the requested amount is within the Pretoria Zoo and North of Fountains Valley and the Willow Road Bridge. Because the bridges are under the Heritage Act they can’t be modified. The openings are not big enough to allow sufficient flow which causes the water to rise and flow over the bridge.

The canal is made of concrete to allow the water to flow quicker. As soon as the concrete is removed it will slow the movement of the water. To control the flow of water, a structure needs to be added to delay its flow. The space next to the canal is limited, which makes it difficult to increase the size of the canal.

We have considered a temporary retention area near Fountains Valley. This area is very flat though. But what is the environmental impact? It has always been known that any changes to the canal will require an additional intervention at Fountains Valley. It will allow more control over the situation.

The Aapies River quality is problematic, but it is not the worst in the area. There aren’t any industrial dumping or sewerage connections to the canal, but there are businesses in the CBD who dump their waste into the drainage systems illegally. Furthermore, solid pollutants such as plastics end in the canal. They are impossible to remove except if a grouse pollution is installed. We have industries

If the aim is to have people access the canal, it will have to be made much safer. It is common to find drifters around the canal. The step edges will need staircases at regular intervals. The Metropolitan Spatial Planning has introduced ‘Operation Reclaim of Inner City Regeneration”, the road works are not aimed at vehicles but to increase the pedestrian corridors. We have noticed the spatial potential along the Aapies River.

Silt can be controlled by allowing the water to stand still for a certain period in an area where the silt can be collected. The Aapies River has less silt than other close by water areas.

The main sewerage line is underneath the canal, but it needs a certain degree of maintenance as it is possible that the waste has been leaking into the canal.

The sewerage line is accessible from the canal via sealed manholes.

We have found companies that discharged storm water in gullies, but the waste pipes are not designed for such capacity. Once we receive complaints about companies dumping unclean water into the storm water system, or if the water starts releasing a strange odor, we can determine the area of insertion by taking water samples, the determined company responsible will be fined.

The canal does not have any heritage protection yet. SAHRA needs to give special permission. But, changes to the canal have been made before.

Your specific site is privately owned and sloped by ‘Urban Spatial Planning’.

They aim to apply a set of requirements to sites next to the canal. For example, the building design must not turn its back towards the canal, new building lines from the canal as existing buildings have mostly been built up against the canal, and between the building line and the water edge it will only allow gardening.”

According to Mr. Jansen van Vuuren the conceptual ideas could serve as possible solutions.

chapter 12 - appendix

“We have consider a variety of initiatives to replace the concrete canal. In the late 90’s we considered hiding the canal with a raised river and replacing all backwards facing buildings alongside the river. What are the chances for converting the canal back into a more natural river with a controlled water level? Buildings along the river are mainly privately owned which makes it difficult to convert the buildings adjacent to the river.

around the canal that have taken responsibility for the canal as it will be to their advantage - It can be described as a PPP (Private Public Partnership).
