Land Sustability Study For National Communicable Disease Quarantine Centre
To identify whether Gombak Subzone is suitable for building a national Communicable Disease Quarantine Centre, it must meet the four decision factors:
1) Economic factor: The selected site should avoid steep slope. This is because construction at steep slope tends to involve a lot of cut-and-fill and will lend to relatively higher development cost.
2) Accessibility factor: The selected site should be close to existing local roads, namely: service roads and tracks. This is to ensure easy transportation of building materials during the construction stage.
3) 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.
4) Natural conservation factor: The selected site should be away from forested land, park and water.
Overview of Gombak: Roads, Buildings, Natural Features and Digital Elevation
ROADS
For the overview of roads in Gombak, I only kept two types of roads, which is service and track roads. I use purple to represent the service road and pink for the track roads. As you can see, Gombak is mostly covered with service roads, with 198 service roads and only 2 track roads. They are mainly situated at the north of Gombak. At the south of Gombak, there is a large area that is not covered by both service road or track road.
BUILDINGS
The location of the buildings in Gombak is similar to the location of the roads. The buildings is mostly situated at the north, east and west of Gombak. At the south of Gombak, there is a large area that is not covered by any buildings.
