Introduction: Prison Scale Model

Picture of Prison Scale Model

Situation: There is an influx of prisoners in the detention facilities in the local area, due to the recent surge of crime. The jailhouses are overpopulated and the guard to prisoner ratio is on the borderline of becoming unsafe

Step 1: Design Brief

Design Brief: A detention facility is required to compensate for the increased number of criminals being incarcerated and being sent to prison.

Panopticon Inspired Design

Waiting Area:

Waiting Area = 12 visitors + one Staff,

· chairs side by side- each chair: 500x500mm, total (4 chair rows):2000x500mm

· Desk: 900mmx1500mm, plus one chair: 500mmx500mm-total area = 2400x1500mm

Total Area: 4mx5.9m =23.6m2

Visiting Area:

Visiting Area = 6 + guards

· Visitor standing area: 5900mm x 2000mm

· Guard area between visitor and prisoner area: 5900mm x 1000mm

· Prisoner visiting area: [5900mm x 2000mm] + ½ (2775mm x 5550mm) = 39.56m

Total Area: 5900mm x 5400mm + ½ (2775mm x 5550mm) = 39.56m2

*Note: Some facilities are not square or rectangular in shape, and therefore require geometric calculations to find out the area.

Prison Cells

Number of People using the facility: 192 prisoners, each in 12 people cells = 16 cells (Note: due to area constraints caused by the laundry and medical room, two cells have been merged into one, and the total number of prisoners have been reduced, however, the theoretical number of prisoners remain same as the original 192.

Parking:

There will be 36 staff and 12 visitors accessing the parking lot

# Of parking spots= Total Number of People [(Staff+ Anticipated Visitors) + 10% Extra Visitors]/10

= [(36 staff + 12 visitors) + 48 x 0.1]/10

=5.28 spots

PIN Parking = # of Parking Spots x 10%

· Width : 0.2m

· Curve Radius: 1m

Ramp Calculation:

Height = 3 steps x Risers (0.2m) = 0.6m

Length = H (0.6m) x 12 = 7.2m

Width: 1m

Foundation

The type of foundation utilized in this commercial building will be a strap beam foundation

Foundation Depth:

= Total Height of Building/3

=H/3

=11500mm/3 = 3833.33mm

Strap Beam Height:

= 2/3 Foundation Height

=2/3 x 3833.33mm = 2555.56mm

Depth of PC:

= 20% of Strap Beam Height

= 0.2 x 2555.56mm = 511.11mm

Overhang:

= 10% Length of PC

= 50700mm x 0.1 = 5070mm

Beam Width: 450mm
