poplar exchange
1 | hub for consumption
poplar exchange aims to expand and build on the community-centric identity of poplar by creating a hub for consumption
make |mÄ k| make aims to create a new community centre for poplar a hub for production, forming a link between poplar exchange and chrisp street market we aspire to provide an environment that is accessible to all and encourages learning and activity through the act of production make acts as an object in the landscape, expressing its function
2 | brief
the bridge acts as a vehicle to direct the community into the hub

feed pipe
The Inlet Tank collects household food and drink waste from all HARCA housing, as well as the soil waste from the building. This is indicated by the underground pipe joining the Inlet Tank from the building. The Inlet Tank then feeds the Anaerobic Digestor, on the far right, through the underground pipe. The Anaerobic Digestor produces biogas, solid and liquid matters. The solid and liquid matters are stored in the middle cylinder and will be used as fertilizer. The biogas is stored in the other cylinder. This biogas is then transported, underground, to the Combined Heat and Power (CHP) generator in the plant room and provide energy to the building. Biogas is also used in the kitchen. The Anaerobic Digestor system is left exposed in order to educate and further push the community towards sustainability and a greener Poplar.

bridge short section
The bridge and ramp have a slight slope from the middle of the structure. Rain water is directed to the gutters and straight down the rain leaders, which are installed along the supports.
gutter detail
load calculations The bridge supports on the A12 carry roughly 22.5m span of bridge. Calculations will be done to demonstrate the total unfactored load carried by a single support in the middle of A12. Taking the self-weight of concrete to be 25 kN/m3, and live load to be 5kN/m2. Dead load for a 22.5m span concrete beam = 346 kN Dead load from the slab = 225 kN Live load = 225 kN
This load is carried by a single support in the middle of A12. concrete support section
bending moment diagram The bridge is formed from a series of simply supported beams spanning varied distances. The largest span is 22.5m and as this length produced the largest bending moments and deflections it was used as the governing length for the beam design.
41 | structural strategy
Total unfactored load = 796 kN
Driven deep pile foundations are used for the supports in the middle of the A12. supports on the A12
Driven piles are considered, as they are neat and clean. They are also relatively quick to install, and thus reducing the construction time along the A12.

48 | post - crit reflection
make was praised for having a very strong design concept with clear intentions in particular the clarity of presentation through drawings and models relationship between bridge and building could be enriched - express the detail and celebrate the junction we were encouraged to be more expressive and creative with the concrete structure, and to make the ‘structure work harder’ the clarity of ideas was well received however one area that we should aim to enrich is the experience of the bridge
develop form of stair as a sculptural object - could become part of concrete language? improve connection between the workshop and digester how could the idea be enriched?
49 | post - crit reflection
if progressed we would like to explore how the bridge could become more than just a vehicle to move people
