WEEK 3 JOURNAL ENTRY
ON SITE (TAKE 1)
NAME: CHAN JOSHUA TIG HAY ASSIGNED CASE STUDY: GROUP MEMBERS:
Structural System(s)_ 1. Steel frames - Exterior walls
1_EASTERN PRECINT STUDENT CENTRE (LINK BETWEEN BUILDINGS)
2. Steel columns and beams -Support roof 3. Cantilever - The roof of the structure is resting on the building on the left-hand side - Load from the roof is transferred to the other building Materials_ 1. Steel - To provide strong framework usually for building exteriors such as window frames 2. Bricks - material used for exterior ground floorings as it is less affected by direct exposure to sunlight and its strength in compression
Potential construction constraints_ - Space between buildings are limited - Difficult to layout footings Links to other buildings_ - Connected to the ERC library which is constructed with large concrete boulders Construction type_ - Type IV Building - Building interior are dominated by timber-surface elements including floorings CONSTRUCTING ENVIRONMENTS
3. Concrete - Used for internal walls 4. Timber -used for interior floorings - take advantage of its light weight characteristic as well as its effectiveness as an insulator to prevent the building interior from becoming too hot 5. Tinted Glass - Used in windows - To absorb a portion of radiation and heat to reduce the temperature of the building interior 6. Metal cladding - Mainly for aesthetic purposes CHAN JOSHUA TIG HAY 638994
1_EASTERN PRECINT STUDENT CENTRE (LINK BETWEEN BUILDINGS)
Steel framework and steel bars on the windows
The roof of the student centre is resting of the ERC building, which is possibly a large cantilever
Joists and beams that support the roof CONSTRUCTING ENVIRONMENTS
Cantilever structure from the interior of the building CHAN JOSHUA TIG HAY 638994
2_MSLE BUILDING (LINK BETWEEN BUILDINGS)
Structural System(s)_ - Cantilevers - Steel framework -exterior of the building -roof system -window frames - Steel Columns - for internal wall support -
Concrete columns
Materials_ 1. Steel - used to make frames and railings 2. Brick - major material for partition walls Potential construction constraints_ - Limited space for expansion and construction - Difficulty in laying the foundation Links to other buildings_ - Neighbouring buildings use different construction materials and construction methods. In this case, they are erected by mass construction using bricks while the MSLE building link was erected with steel frame structure Construction type_ - Type IV Building - There are non-combustible exterior walls including steel and major interior elements of laminated wood such as timber floors
CONSTRUCTING ENVIRONMENTS
3. Timber - to create railings for staircases - Laminated timer is used for more aesthetic floorings 4. Concrete -To create staircase, interior walls and floorings for strong 5. Glass - As the primary material for interior and exterior windows - Also used to complement railings as an aesthetic element 6. Plasterboard -Mainly act as cover for roof systems and walls to give an aesthetic finish

2_MSLE BUILDING (LINK BETWEEN BUILDINGS)
Concrete staircase with timber hand rails
Plasterboard as a cover to the structural framework of the roof
Bricks and concrete blocks as the material for making the walls CONSTRUCTING ENVIRONMENTS
Timber floorings

3_QUEENS COLLEGE EXTENTION
Structural System(s)_ 1. Steel frame - roof structures 2. Cantilevers - Steel roofs act as cantilevers but are supported by steel columns - concrete roofs are cantilevers as well 3.
Concrete columns
4. Construction joints - allow the construction process to stop and continue at a later time Materials_ 1. Concrete - To support strong compression and act as fire-proof material - To make exterior floorings which are exposed to sunlight most of the day
Potential construction constraints_ - Non-linear topography affects difficulty in laying the footings Links to other buildings_ - Joints between the old and new buildings are connected with cement Construction type_ - Type I - Building material is dominated by non-combustible material concrete throughout the exterior
2. Glass - Used to make semi-see- through windows 3. Waterproof cladding - Present within the exterior walls - acts as an insulating material to prevent rainwater from entering the interior of the building - also used to direct rainwater away to the ground 4. Timber - to make doors and add an aesthetic finish 5. Steel - material for the handle for railings - they are used because of their ability to resistant erosion and the effect of rusting

4_ORMOND THEOLOGY CENTRE RECEPTION
Structural System(s)_ 1. Steel columns and beams - black steel colums as structural support for the planks which make up the ceiling in the reception 2. Concrete column - they support the overhanging beam which acts as the roof 3. Steel frames -make up the exterior -for window frames 4. Cantilevers -as overhanging roofs Materials_ 1. Concrete - To make exterior floorings - Concrete columns act as a support for overhanging beams
Potential construction constraints - difficulty in laying the foundation footings as it may affect the stability of neighboring buildings - restricted support for roof systems as there is a lack of space for roof beams
2. Steel - To make window frames
Links to other buildings_ - connected to the faculty of Theology building which was built with sandstone - connected to the Dalton McCaughey Library which has a similar steel frame structure
4. Glass - As material for windows as well as doors due to its transparency and aesthetic finish
Construction type_ - Type I - Major building elements are non-combustible masonry, such as concrete columns, steel frames and concrete tile floorings CONSTRUCTING ENVIRONMENTS
3. Wood - To make benches due to its ability as a heat insulator
Other relevant comments - Mechanical structures including water pipes and drainage systems are connected between the reception and the faculty building - drainage covers or gutters are made using steel frames

Steel widow frames with an aesthetic finish
Semi-see through glass as material for the external wall
Large concrete columns supporting the roof Steel Beams and columns within the interior of the reception Long steel bars to hold the steel plates with tension

Oval Pavilion
Photo 1: Pipes and footings
Soil and loose mud is shown in the photo and indicates digging process to lay out a footing system for the construction of the fence for the Cricket ground. It is currently at a stage of foundation construction as only steel framework is observed with plastic caps on them for protection during the construction process. Underground water is also observed which indicates that water pipes are being fixed and fitted underground for sewage transfer from the facility.

Photo 2: Exterior walls
An exterior wall is observed which is cleared constructed by concrete. Reinforced concrete is used as the concrete blocks are connected with one another with steel bars. There is also black waterproof cladding existing between the layers of concrete blocks to divert rainwater and act as an insulator to prevent water from entering the building. It is currently at a stage of building the exterior walls from the ground floor level.

Photo 3: Column and beam frame
The photo shows the construction currently at a stage of placing planks as the floor for level 1 of the pavilion. Steel bars and steel joists are observed which make up the structural system for laying the planks for the floor. In addition, steel columns and beams are observed along the walls of the building which are the structural systems for constructing the exterior walls.

Photo 4: Existing structure
This existing structure forming part of the pavilion is currently being renovated. Structural systems within the interior of the building are being reinforced. Wooden planks are observed which act as support during the reinforcement. In addition, a steel framework of the original structure can be identified as well.
