National Communicable Disease Quarantine Centre – Gombak
The main objective is to locate a suitable location within Gombak, the selected location, to build a National Communicable Disease Quarantine Centre with a contiguous area of minimally 10,000m2. Also, the following factors must be met:
- Economic Factor: The selected site should avoid steep slope.
- Accessibility Factor: The selected site should be close to existing.
- Health Risk Factor: The selected site should be away from population i.e. housing areas and offices in order to avoid disease spreading to the nearby population.
- Natural Conservation Factor: The selected site should be away from forested land, park and water.
Roads
Shown in the top left picture. The accessibility factor is linked to roads, specifically – Service Roads and Tracks. During the construction phase of the Gombak National Communicable Disease Quarantine Centre, it is ideal that the quarantine centre be located near these specific types of roads to easily transport all the relevant building materials. This could potentially save construction time and cost. However, it is observed that these most of these roads are located at the northern part of Gombak and that there are a total of 2 tracks and 186 service roads, where these two types of roads are marked by different colors.
Buildings
Shown in the top right picture. The health factor is linked to buildings. When selecting a suitable site for building the quarantine centre, it is important to take note that the centre is located away from the population to prevent the spread of diseases. It is observed that there were missing buildings. Thus, I took the initiative to identify the missing buildings via openstreet map and google maps (satellite images), cleaning the data. There are 10 different types of buildings with military and residential building taking up majority of the land. Additionally, it is observed that most of the buildings are situated in the centre and northern part of Gombak. Therefore, it is possible to consider building the quarantine centre at the southern end of Gombak.
Natural Conservation
Shown in the bottom left picture. The natural conservation factor is linked to natural features. When selecting a suitable site for building the quarantine centre, it is important to take note that the centre is located away from forested land, parks and water. There are 3 water bodies in total with one main water catchment located up north of Gombak and 2 water bodies, taking the shape of 2 separated long streams, that possibly from the north to south of Gombak. There is a 1 forest located North-East part of Gombak and a total of 4 parks scattered across Gombak (North – West – South).
Digital Elevation
Shown in the bottom right picture. The economic factor is linked to the digital elevation. When selecting a suitable site for building the quarantine centre, it is important to take note that the centre is located away from steep slopes which potential result in a lot of cut-and-fill, leading to higher development cost. The lowest point is 8m and the highest point is 143m in Gombak. This explains the reason as to why most of the buildings and roads in Gombak are situated in the northern part, elevation/steepness is relatively low, as compared to the southern part where the elevation/steepness are higher.
