Constructing Environments Week 3 Journal - Case Study
Daniel Kellett 635876
The old pavilion site will remain as part of the redesign of the area and will be joined into the new design. The structure is of a wooden framework design and these wooden structures act under compression in supporting the structure. This structure is completed, however with the new designs underway, the future building will incorporate new technologies and so the heritage building will have to undergo renovation in order to improve the supporting structure so that it can withstand the pressures of the new structure that is being constructed.

Figure 3. Back Section Reinforcing Wall The back section of the site is the most completed out of the rest of the project. the foundations, slab, walls and supporting structure have been constructed and at this stage the supporting wall is undergoing its final steps from completion. The exterior of the wall is also undergoing water proofing, seen in the small image left of figure 3. This will protect the underground level from water. The space you see in figure 3 next to the wall will soon be filled in with earth and so the entire first floor has been constructed in order to withstand the lateral forces that the surrounding ground is acting inwards on.
Figure 2. Seating Area Foundations Figure 5. Site Plan - Oval Pavilion This section of the site is currently undergoing foundation work, with piles in place and pipes & tubing now being placed in, as seen in figure 2 on the left. This area is still at the early stages of construction and will now undergo slab work and the flooring for the seating section that will host the audience when games eventually resume in this area. Materials for this section include steel reinforced concrete that will form the supporting wall and parts of the slab. steel piles are used to anchor the site into the ground and maintain its stability. The piles and slab will eventually be under compressive force from the structure above which is their purpose - to transfer the weight of the structure down into the ground.
The entrance into the change rooms below ground is progressing well with the piles and ground floor being completed, the result of this is that the entrance to this space is now being constructed. The pilings for this entrance have been constructed and the supporting wall frame has being placed in, as seen in figure 4 on the right. From here this frame will be filled in with concrete and possibly steel reinforcing bars in order to hold back the pressure of the surrounding earth. This wall is under lateral force, with the concrete being placed under compression from the structure that will reside above and the steel under tension, holding the structure in placed.

Potential Construction Constraints: Historical sections in two adjacent buildings, structural strength of adjacent buildings.

Links to other buildings: This space forms a link between the two adjacent sites. This generates an additional space that can be used by students and staff that is encased in a structure that allows for an exterior feeling while being protected from the weather. The materials used are in sync with the two other sites and so the link connects with the two buildings and flows between them Construction Type: This is a framework structure with no new supports from the link to the ground. The build uses the support structure of the two adjacent sites to hold it up. This determines the materials used as they must be strong but light weight. Structure Systems: The structural systems employed are: cantilever, framework, compression, tension Materials: • Steel • Roof - Horizontal supports, guttering systems on the exterior • Supports - pilings into the ground (part of foundation) • Reinforcing - Within concrete that acts to counter tension forces • Concrete - Compressive structure that creates the superstructure of the site • Aluminium - Cladding features and rims to the facade • Glass - Facade features that clad the building

Figure 10. Previous Door Frame Hole Potential Construction Constraints: The size of the site is very small and so certain techniques cannot be employed within the space without detracting from useable areas when completed. Historical consideration must also be taken into account when altering the site. Links to other buildings:
Figure 9. Elevated Cantilever Walkway Structure Systems: The structural systems employed include: Compression, tension, cantilever, framework. Materials: • Brick - Acts as the exterior wall panelling for the previous structure. • Steel - The support and anchoring structure that holds the framework structure upright as well as holds the cantilevered walkway in place. • Glass - Forms the cladding of the building • Concrete - this is not used in the new site however remains from the old site and acts as the slab for the upper sections fo the site.
The site sits between two other buildings and forms an internal connection between the two facilities. This space does not require much structure as it simply joins the two space, rather than creating a space that is used for means other than motion on a regular basis. Construction Type: The structure uses a framework that envelopes the space between the two buildings. This framework is joined to the preexisting buildings which act as the support structure of the frame to attach to. This frame work is then cladded in a glass facade which completes the space.

This site is being constructed within an historical site and so considerations have to be taken into account such as the materials used, the alterations to the previous site and the size/shape. Links to other buildings: This building links into the previous site, however the support structure itself is separate and so simply joins the other building internally. Construction Type: The mass construction uses simple concrete slabs with steel reinforcement to create a simple box structure. Structure Systems: The structural systems employed are compression and tension and Framework for roofing systems. Materials: • Glass - Window facade • Concrete - Wall and slab • Steel/Aluminium - Roofing and guttering system.

This site does not face as many historical constraints as the others due to the linkage being with a new building, however consideration was paid to the walking space in between the old site to the right of figure 18. and the new building to the left of figure 18.

This site is an extension of the previous centre and so has its own support structure but is joined to the previous one in order to join the interior space. Construction Type:
Site
The construction type uses conventional means with creation of a slab then the construction of a framework and cladding structure to complete the project. Structure Systems: The structural systems employed include: tension, compression, cantilever and mass construction. Materials: • • • •
Concrete - facade support structure, seen in figure 17, slab formation and wall formation Glass - facade and cladding system as seen in figure 18 and 16 Aluminium - Roofing and guttering as well as rimming for the glass facade Steel - support for the concrete slab • Pilings as part of the foundation to support the structure.
