FACTORS CONTRIBUTING TO CONSTRUCTION STRATEGY
Considering the current financial climate, as well as a number of other factors as outlined in the flowchart, the building would require involving the community as part of the construction process. This not only reduces labour costs, but has a pedagogical value, as well as an increased ownership in the produced landscape.

Tamped Clay and Art Materials
2.1 Construction as Community Building Gathering upon the points and factors as mentioned above. This project, in its construction would relate different forms of industry, from the ‘high tech’ to the ‘low tech’, creating a cross fertilisation of techniques and hybridisation. For instance, children, who typically might not at all come into contact with techniques such as laser cutting, or computer generated models could have an opportunity to visualise their designs within a prototyping technique.
Cross fertilisation across industries and sectors
66 Dissemination of Knowledge
Overall Computer Model
Target Users Typically, each party is seperate in producing their own aras of specilisation in contribution to the overall architectural product. In this building, each sector interacts and learns directly from the other, forming a building cooperative that ranges in technology, skills and knowledge.

2.2 Material Selection and Performance
Overall Selection
67
Material selections of the construction is selected based on 3 time spans. Long, medium and brief. This builds upon the previous section of high tech vs low tech construction. Materials are recycled where possible. Materials under the medium life span headings are already available through the playground junk yard that is in place.
Long Life Span
Medium Life Span
Structural frames, load bearing structures
Recycled materials to construct Surfaces, openings, frames, constantly used with wet materials
Tamped clay is a form of earth or mud construction, a variant on rammed earth. Tamped clay can be constructed by all members of the community and would be used as a permeable wall between the garden and the private residential units.
Ephermal Craft materials, lasting briefly in their current form, but could be recycled and reused.
Glue laminated timber is chosen for its availability and strength. Bespoke shapes would be manufactured offsite.
WET ceramic pots
Oak is used for most of the vertical structural elementts.
fired ceramic materials
Ceramic tiles are used to clad roof surfaces for both aesthetic functions as well as environmental reasons. It is also constantly produced in the playground itself as part of the children’s art classes.

2.2 Constructional Phases
Schematic View
The project, as stated in the previous spread, is going to be constructed in 7 phases. Out of which, this report is going to focus on 4 of these phases. The other 3 phases would follow a construction sequence and detail very similar to the others. The materials and structural strategy of each phase has been chosen for a specific purpose owing to its nature for speed, time etc.

2.3 Greenhouse Structure
Steel Arch Portal Frame
70 Construction Phase
There are a number of design criterias for the Greenhouse: 1) Functions in both summer and winter conditions.
Ceramic Tiles
Glazed ceramic tiles offer some shaded area towards the North of the greenhouse
2) Can be a testing ground for material qualities of light, insulation. Eg. Children can try making an enclosure out of plastic bottles. 3) A Legibility to users. What is structure and
Operable insulation
Main Materials
Prefab Steel Beams
The primary structure would be a series of prefabricated steel beams which are manufactured offsite for quick assembly onsite.
The aerogel insulation can be operated by the public to insulate the greenhouse. This is achieved by hooking a rope onto the attached handle.
7
5 6
Prefab Steel Structure
The holes in the steel structure reduces weight of the structure that is high above the ground, thus relieving the columns of some bending moments

Concrete Pad Foundations
The building is relatively lightweight and no rafts are required. Steel shear bolts and channels would be cast into the concrete for joining the steel elements

3 Aerogel
More expensive aerogel is coated with glass fibres. A cheap form is similar to large bubble wrap.
These elements are lightweight and can be folded out to hold plastic sheets, bags, bottles that children come up with., producing a mini greenhouse in their own right

The taller side of the structure would be used to store plant pots, which might otherwise be a safety risk to children

2.3 Arch Portal Steel Frame Portal Frame Structure Precedents Portal frames can be defined as two-dimensional rigid frames that have the basic characteristics of a rigid joint between column and beam. The main objective of this form of design is to reduce bending moment in the beam, which allows the frame to act as one structural unit.
Structural Analysis
71
Initial Structural Proposal
Prevailing NE wind
The transfer of stresses from the beam to the column results in rotational movement at the foundation, which can be overcome by the introduction of a pin/ hinge joint.
Possible Failing points Critical junction subject to shear Elements required here for wind load
Key Tectonic Joints:
Axial Loads The axial loads of the roof meets the foundation and columns at rather awkward junctions. The Junctions have to be mitigated better to prevent failing at the junctions.

Bending Moments of the Arch Portal Frame Based on the existing diagram. There are multiple locations of possible buckling or failure. Therefore, the Main Steel frame should also be manufactured, then bolted together in parts to strengthen it.
Elements in Tension Elements in Compression
Final Structural Proposal egm ent
Based on earlier investigation, the final structure invovled the following key decisions:
2
Between the Beam: Apex Hauch The joint between two members of the beam to prevent buckling in the beam.
- The main structure is manufactured in 3 separate pieces of steel. These are appropriately joint to each other to resist shear and the transfer of loads - Cross Bracing elements are utilised in the main structural body to resist wind loads.
Beam to Column: Knee Joint The joint between the beam and the column is critical as it involves the transfer of stresses

2.2 Greenhouse Construction
Children Operability
74
One proposed acitivity for children is to build their own enclosure. These is done with salvaged material they find in skips or donated to the playground itself. Timber louvres behave like hanging cases where bottles, bags could be wrapped or suspended.

Precedents
Bottled greenhouse as constructed by children.
The timber louvres can be lowered by children, thus making a hanging screen to hang objects upon.
Items such as bottles are tied and hung upon the vertical timber slats. Horizontal elements offer stability. At the edge of the timber frame, there are two holes for rope to tie the elements together.
Once the frame is filled, it is raised back upwards onto the steel frame
Ropes are then suspended from the main tmiber frame. Additional vertical bottles can be suspended, starting to form an enclosed space.

2.5 Building up the Rammed Earth Rammed earth is an ancient building method that has seen a revival in recent years as people seek more sustainable building materials and natural building methods. Rammed-earth walls are simple to construct, noncombustible, thermally massive, strong, and durable. They can be labour-intensive to construct without machinery (powered tampers), however, and they are susceptible to water damage if inadequately protected or maintained.

The construction of the clay wall could also be carried out on a rainy day. Therefore, water could be of abundance.

1 - Basic Timber Frame. A basic timber frame is erected. Each panel is a module of the structural grid. The frame needs to be painted with protective coatings.
2 - Reinforcing the Timber Frame Horizontal and Diagonal elements are added to the timber frame to reinforce the frame. These joints would be hidden by the rammed earth.
Getting the right texture and mix Timber framed Clay infill construction. High street buildings, Shrewsbury, UK
To test the desired texture, table top tests could be carried out initially in the park. Ideally, the rammed earth could clump into a ball in your hand without falling apart. This indicates the right proportion of mix. Table top tests for clay mix
Term 1 Test model: clay wall constructed on existing timber frame. Pots, or objects of the childrens’ creation could be picked out to be embedded on the earth surface. Not only are they for aesthetic purposes, they also serve as reinforcement, by preventing excessive movement of the mix. Reference: Gando Library by Francis Kere
Secondary Supporting Timber
3 - Placing the Timber Panel. The timber panel is then covered with a sheet of plywood. The structure is placed on top of the diagonal timber buttress. Secondary supports and planks are used as necessary
2.5 Building up the Rammed Earth
Construction of Wall surface itself
Due to the high labour costs, much of the Tampered Clay community projects are actually constructed by the public. Not much training or specialisation is required. This activity would be carried out by the volunteers and children alike.

2.8 End of Construction
Refitting the scaffolding working platform
88
At the end of construction, the temporary structural posts of the scaffoldings could be recycled into a mobile seating area. This could be used firstly, for maintenance, but also, for children to replace the tiles they’ve hung etc. The scaffolding is also visually reinvented by introducing a bright coat of yellow paint. Balustrades are built with permeable mesh material to maximise transparency.

2.9 Children’s Role in Construction
Notification and Signage for Children
89
It is worth noting, that children’s skills in construction is not to be underestimated. In the post war period, when Health and Safety rules were not as strict as today, children were allowed to play with building debris at bomb sites, using adult tools to build their own spaces.
1.
Use a roller on top of some sticks to roll the lump of clay flat
4.
Scratch the top part of the tile with the needle tool
9.
2.
Place the clay template you've cut onto the clay and trace the outline with a sharp tool. Be careful of your fingers!
5.
Slowly, bend the clay piece backwards with your fingers. Then, apply slip clay onto the scratched portions.
9.
3.
Your Clay tile should now look like this!

2.9 Children’s Role in Construction
Colour Coding for information and safety
90
Upon arrival at the park, children would be briefed on the various colour codes in the playground. This would ensure that children are aware of certain behaviour of materials that they can use accordingly.
Look out for these shapes and Colours!
Do not touch! Ask a grown up to assist
Add some water, and see what happens!
Stack and Join!
Plant a seed!
Open and reveal!
Fold and glue
2.10 Construction of Material Workshops
Blurring the respective roles between children and adults
91
It is worth noting, that children’s skills in construction is not to be underestimated. The architecture of the building goes through a process of scaling down, as the building expands from its inner structure to its outer shell. This allows the capacity of children to build and move to manifest in the architectural design itself.

LABOUR
KEY New addition at a particular Stage Constructed elements so far
1 The Primary structure is already set in place by contractors. The volunteers would have to create a rigid timber grid to lift the floor level of the plant roof slightly off the ground level.
4 The primary structure and timber members are filled with tamped clay. This process could involve childrne.
2
3
The vertical frames are erected. Each column is a composite element of 3 pieces of 75mm x 150mm sections bolted together
Additional Timber frames are added to the main vertical structure
5
6
The ‘learning support’ frames are put in place. Children can start to construct once materials are placed into the frames
As the workshop reaches some level of completion, adults would construct the start to prepare the roof structure to seal the building.
7 The roof structure is a timber frame clad with numerous clay tiles produced by childrne. These panels would be loaded onto the roof by adult volunteers.
2.10 Construction of Material Workshops The right facade of the material workshop is a material shelf. The shelf itself is cladded in loose clay tiles that are removed or shifted as children use materials within. The loose clay tiles is used as building material for the rest of the building. Loose tiles can be modified, stuck together, hung and joint in various manners that are easy, yet educational and offer opportunities for personal intepretation.

Workshop as constructed by children
The building, as construced by adults, is a timber framed structure with carefully designed bits of detail to envision further kids based construction.
Children use and adapt the workshops existing fabric and uses given materials to construct new enclosures and screens. It enlivens the timber frame with both uniques and variety
2.11 Construction of Display Corridor
96 Construction Phase
Design Criteria forDisplay Pavilion
4
This is phase 4 of the project. By this time, the park would have produced an immense amount of artworks that has to stored. Rather than simply recyling or storage, the playground breathes new life into clay material by utilising them as construction material. This section of the playground gives children even more autonomy then before.
Children Controlled Materials
Green roof
Perforated and screen openings
Perforated Timber panels allow views outwards to the exterior. Children should be able ot mediate and control these views
A roof constructed with clay pavers. Children construct the roof material as well as the vegetaion above. Acoustic Curtain
Roof
The glazed tiles offer some shade, whilst the corrugated plastic brings natural light into the play sites beneath
Stringed Tiles
Reference: Giles Miller Interior Design Timber Cross Bracing
+0.50m
Clay pavers
Clay pavers can be constructed by children. The fired clay is porous and ideal for filtering water and allowing small amounts of vegetation to grow within it.
Discussion and Workshop Room
Shaded Terrace Area
The terrace area could be used for informal play and Hanging out for children. This area is shielded to the football pitch by an acoustic curtain. When the need requires, this curtain could be deployed to cover the football field.
Display boxes
Screen.
The indoor display area and the outdoors is mediated with a screen that is constructed by children. Adults would construct a Sliding frame, whilst children fill it with their creations
Boxes and Blocks
Children would instinctively know how to use these materials. The idea here was to utilise this instictive reaction to loose material in the design
-1.70m
The artefacts brought from external organisations are stored in display columns. These operate like lightwells. When obkects are removed, light passes through the steel cage.
A cosy, enclosed classroom for discussion and reading. The screen here again can be constructed by children.

2.11 Construction of Display Corridor Structural Analysis
98
The display corridor consists of an enclosed display area, as well as a sheltered terraced level. The structure rests on a datum 1.8 below ground level and the vertical structure
Timber Roof Structure The roof extends beyond the timber vertical column, creating an overhang where axial load would be exerted. The main roof beam is braced with secondary Timber Vertical Columns The timber vertical columns are composite columns made up of two timber sections with timber and steel spacer blocks Timber Cross Bracing The cross bracing elements are alternated between the structural grid. Where there isn’t cross bracing, the structure would be braced by the internal light and wind well, and would be further elaborated in the following pages.
Timber Floor Joists Timber floor joists brace the two vertical columns. It is further strengthened with the vertical columns with steel diagonal bracings

2.12 Construction of Waste Station and Fence Biodigester and Fruit Fence
105
This section of the building aims to educate and enliven public knowledge about both agriculture as well as waste..
Construction Phase
The waste station and fence is located at the perimeter of the site. he fence could be curated by external organisations, providing particular seeds or fertilizers. This forms a vertical green wall, with plants growing in DIY bags. Part of features is the mobile boundary, where a lightweight floors rotates to grant admission to the park on certain occasions, such as planting sundays. The fences are filled with hanging bags of plants, giving each member of the community a token of value.
Fruit Fences DIY planter bags are hung off this permeable fence, making it effecitvely a green wall in which everyone contributes a unit. Temporary Exhibition Area A shaded are for public exhitbions etc. The ornamented fence provide display and advertising opportunities Mobile Gate A gate that can be rotated along a fixed point by 90degrees. The rotation of this gate determines the nature of the actvities. When it is closed, it is used as a studio space for the waste treatement room. When it is opened, it is used as part of the temporary exhibtion space.
Waste Treatment Room The biodigester machine is stored within this waste treatment hut.

2.12 Construction of Waste Station and Fence Exploded Axonometric The rationale behind the fruit fence was to have the notion of growth on the perimeter of the site. The fence could be curated by external organisations, providing particular seeds or fertilizers. This forms a vertical green wall, with plants growing in DIY bags. Once the plants reach a certain stage of growth, they can then be taken home by the community or transplanted elsewhere in the site.
