Workshop four - engineering & bridges

This month’s Shape My City blog post is written by project participant Cai Burton.

This blog post is brought to you amidst stacks of past papers and revision notes, as all of the Shape My City members are well into exam season. However, with two hours free on a sunny Thursday evening, we were able to relax a little and immerse ourselves in session four of the project. This week, we were lucky enough to be joined by Fiona Gleed who is a lecturer at UWE in civil engineering.

Next, Fiona gave a short presentation about her experiences as a Structural engineer. It was really interesting, and it gave me a great insight into what engineers actually do. Engineering is a word that gets thrown around a lot, but she really made clear what it means to be a structural engineer. She shared her story and all her different experiences of structural and civil engineering that helped lead her to where she is now. She shared that she was a part of the construction of The Mall in Cribb’s Causeway, and how she worked on the fountains at the centre. It was really interesting to hear this as years later, you can still physically see the impact she has made!

Finally, we were given our design activity! This session, we needed to design a striking new bridge over the River Avon to link to the new Bristol Arena site. With this brief, we needed to think about how we could allow pedestrians, cyclists and car drivers to all use the bridge safely. We also needed to ensure that the bridge has a striking design which contributed to the regeneration of the wider area, helping to make it a ‘destination’. The design brief also encouraged us to consider:

  • the type of bridge structure (beam, arch, truss, etc.
  • the distance that needs to be spanned (max 40 meters
  • the materials – what will the bridge look and feel like?
  • how the bridge will form a connection between the city centre/railway station and the new Arena ‘island’
  • the bridge being an iconic structure for Bristol and its new Arena?
  • the risk of future flooding of the River Avon (climate change).

With all this in our minds, we set to work! The group split into three smaller design teams, each with their own ideas about what the bridge would look like. In my team, we decided we wanted to create either a suspension bridge or a cable-stayed bridge. This would be so that it would create the appearance of a ship’s sails from afar – echoing Bristol’s shipping history! We had a lot of discussion over what type of bridge it would be – whether to go for a suspension bridge that similar to the one over Avon Gorge, and that could be curved, or to go for a cable-stayed bridge that would be more structurally sound (this was the one endorsed by Fiona!). Once we had settled on our design, we drew up our design concepts,  ready to present to the other groups.

The two other groups came up with some really cool designs. The first group presented their aptly named “Alan’s Bridge” which consisted of a couple of overlapping paths that were designed for all the different users (pedestrians, cyclists and car drivers). It was really futuristic and like something I’d never seen before, and it would have definitely become an iconic structure for Bristol.

The other group came up with a similar overlapping shape, but with a completely different spin on it. They looked at the existing roads and tried to create a design that would fit with them – taking the users  across two different overlapping routes. It was Fiona that spotted the only issue with this design – that the cars would end up on the wrong side of the road! However, she explained how a bridge like theirs had been used to span the border of two countries, swapping from one side to another, as the traffic system was different in the two countries. The group refined their design, and came up with a modified suggestion that looked just as good and functioned even better!

This week’s design brief was really interesting, not just because we were designing bridges, but because it is such a current topic! Shortly after the session, an article was released in the local press saying that work has begun on the bridge over the River Avon, connecting roads to the site where the Bristol Arena would be. The fact that this happened so shortly after the session left a few of us wondering if it was any coincidence! The Architecture Centre really does try to make the context of our session relevant and topical!

We rounded off the workshop with Fiona’s ‘hot seat’ session, where we were lucky enough to get the advice she would give her 16 year old self, knowing what she knows now about her life and career. ! Then with that, we ended our fourth Shape My City session.

As one of the 'City Shapers', I really enjoyed the workshop! I felt that it gave me a great insight into the world of engineering, and the design task was lots of fun - I’m looking forward the next one!

Fiona also reflected on the session:
‘The participants showed great creativity in their designs for a new bridge to the Arena site.  I was really impressed by the way they considered the spatial geometry of the approaches as well as the appearance and structural function of the bridge.  The solutions produced were attractive and anticipated a full range of active travellers once the construction of the Arena was complete.  It would be very interesting to see their comments on the actual bridge, which is just starting on site’She added 'The young people certainly demonstrated the skills that RAEng have highlighted in their report on how to Think Like an Engineer'.

Workshop three - architecture and learning spaces

Fraught with looming exams and deadlines, our young city shapers set aside any impending pressures for the third Shape My City workshop, which saw local architect Terry Pinto from PAAD on hand to impart his architectural expertise. Volunteer planner Andy Bell was also present to provide advice from a planning perspective.

At the start of the session, group members Cai and Hani shared their recent experience with London based architectects and artists MUF. This involved them researching the usage of an area of public space close to their school to feed into development plans for the local neighbourhood forum.

Terry imparts his wisdom
Terry then opened the session by sharing the highs and lows of his career; ranging from his degree in Birmingham, to his varied time spent working in Madrid and London. With Bramble, his canine companion in tow, he engaged our city-shapers, providing a glimpse into his diverse career path by sharing:
  • the highs and lows of a career in architecture 
  • the impact of recessions on his career
  • how his social conscience has influenced his projects/clients 
Discussing design ideas

Next, as a warm up for their design challenge, the young people played a word association game prompted by images of a range of buildings. Asked to provide one descriptive word for each building, Krishna Avanti Primary School was branded ‘beautiful’ and the Guggenheim ‘shark-like’. Other descriptions included: abstract, relaxing, echo, playful, origami and unique. The common theme of these diverse images was that they were all types of learning environments (schools, nurseries, colleges, museums, galleries, libraries, universities, outdoor classrooms), which got our group thinking about new and innovative ways of designing spaces for learning.

The group were then prepared to tackle their design brief to design a future learning space. Equipped with an infinite budget, pens, paper, inspirational images and their creativity, they divided themselves into two large groups, before sitting around the table to intently discuss their ideas.

Visioning future learning spaces
 With Terry Pinto’s statement that ‘if it’s boring I’ll tell you’ ringing in their ears, the young people set about giving free reign to their creativity.

They made sure to consider key factors:
  •     age of learners
  •     flexibilty and comfort
  •     inspiring
  •     fit for purpose now in the future
  •     environmentally sustainable

The first group opted for a non-site specific 'study-pod', where each member designed an unique space. One underground pod included a solar paneled tree feature, whilst another involved an inbuilt refreshments area (to provide coffee for tired students). They also considered building storage into the exterior design so as to free up interior space, and reflected on the various uses of the space in relation to its function. The second group developed designs for a Performing Arts Centre for the elderly. Featuring separate spaces for different artistic activities, they located the space within a forest, and used sustainable construction materials, such as wood for its carbon retaining abilities. Other features included a special ‘rabbit-hole’ feature inbuilt into the natural terrain, and a pond surrounding the entrance.

The final designs
Both Terry Pinto and Andy Bell were highly impressed with the innovation and creativity of the designs. Providing constructive feedback, they considered the possible drawback of the entry pond as a barrier to visitors, as well as the merits of various sustainable building techniques - from wind turbines and solar panels to the use of bio-mimicry. 

We asked Terry for his reflections on the workshop:

'As a teenager I had no idea what architecture entailed, so I felt it was important to participate with Shape My City. What I found were engaged young people who were actively interested even when I told them some of the stark realities of being an architect in today’s world. Despite this they produced interesting work that would not have gone amiss in the early years of an architecture degree. Well done! I hope that that they maintain their enthusiasm and heed my words of advice- to be passionate about their work whatever they do.'
