Workshop 2

BLDG1024: Construction & Property Economics Semester 2, 2017

Q1. For the drawings shown in Fig. 1, calculate the Floor Area Ratio (FAR), Ground (Floor) Space Index (FSI), Open Space Ratio (OSR) and coverage Assume that the Open Area is 20% of the Land size Also, assume that the total area to be built is comprised of the Floor Space + 100𝑚2 fenced region.

Fig.1 Plan views of land and floor areas

Q2). You are about to construct a development in the Municipality of Burwood. The area of the land is given as 1000𝑚2 . You are required to build 15 stories. The stories are arranged as follows:

• • • •

Group A: Storey 1 - 5 to have the same area Group B: Storey 6 – 10 to have the same area Group C: Storey 11 – 15 to have the same area Ratio of the areas of Group A: Group B: Group C is given as 3:2:1

The regulations and requirements enlist the following as compulsory figures to abide by: • • •

FAR = 1.5 OSR = 0.02 𝐵𝑢𝑖𝑙𝑡 𝐴𝑟𝑒𝑎 = 𝑂𝑝𝑒𝑛 𝐴𝑟𝑒𝑎 + 𝐿𝑎𝑟𝑔𝑒𝑠𝑡 𝐹𝑙𝑜𝑜𝑟 𝐴𝑟𝑒𝑎 𝐺𝑟𝑜𝑢𝑝 Note: Here we are assuming that open area contains buildings and hence is included as part of the built area

Calculate: I. II. III. IV. V.

The area of each storey group The gross floor area The open area The built area Ground (Floor) Space Index

Q3). How would you redesign an area with a FAR =1 and coverage of 100% to an area with the same FAR but coverage of 25%? Show your answers via drawings...
