The IAB Professional Practice exam is a 2-hour test costing around BDT 5,000. It is administered by the Institute of Architects Bangladesh for candidates seeking full professional registration. The exam covers Dhaka Mohanagar Imarat Nirman Bidhimala 2008, BNBC 2020, the IAB Code of Ethics, and standard construction contracts. Earning your MIAB credentials is required to legally sign building submissions in Bangladesh.

1What is the primary definition of the Floor Area Ratio (FAR) according to the Dhaka Mohanagar Imarat Nirman Bidhimala 2008?

A.The ratio of the building footprint area to the total width of the adjacent access road

B.The ratio of the total gross floor area of all floors of a building to the total area of the plot

C.The ratio of the mandatory open space left on the plot to the maximum permissible building height

D.The ratio of the basement floor area to the total ground floor area of the building

Explanation: Floor Area Ratio (FAR) is defined under the Dhaka Mohanagar Imarat Nirman Bidhimala 2008 as the ratio of the total gross floor area of all floors of a building to the total area of the plot. It is used as a density control mechanism to regulate the volume of construction on a given piece of land. Higher FAR values are typically allowed for larger plots and wider access roads.

2Under the Dhaka Mohanagar Imarat Nirman Bidhimala 2008, which of the following represents the main method to calculate total built-up area allowed on a plot?

A.Total Area = Plot Area / Maximum Ground Coverage (MGC)

B.Total Area = Plot Area * Floor Area Ratio (FAR)

C.Total Area = Plot Area - Setback Areas

D.Total Area = Footprint Area * Road Width

Explanation: The total built-up area (excluding exempt areas like car parking and lift lobbies under specific conditions) allowed on a plot is calculated by multiplying the plot area by the designated Floor Area Ratio (FAR). This calculation determines the maximum capacity of the building. The actual footprint is further constrained by the Maximum Ground Coverage (MGC).

3Which of the following factors is the primary determinant of the allowable Floor Area Ratio (FAR) for a plot under Dhaka building bylaws?

A.The total construction budget of the project

B.The land area of the plot and the width of the adjacent access road

C.The orientation of the plot relative to the cardinal directions

D.The number of residential units proposed by the developer

Explanation: Allowable FAR under the Dhaka Mohanagar Imarat Nirman Bidhimala 2008 is determined by two main parameters: the size (area) of the plot and the width of the adjacent access road serving the plot. Larger plots and wider roads are assigned higher FAR values to encourage higher-density development where infrastructure can support it. Plot orientation and budget have no bearing on FAR.

4What is the minimum mandatory front setback distance for a standard residential building on a plot under Dhaka building rules?

A.1.0 meter

B.1.5 meters

C.2.5 meters

D.3.0 meters

Explanation: Under the Dhaka Mohanagar Imarat Nirman Bidhimala 2008, the minimum front setback required for a standard residential plot is 1.5 meters (approximately 5 feet) from the plot boundary adjacent to the access road. This setback ensures a clear visual buffer, space for utilities, and road widening allowance. The front setback cannot be violated by primary building columns or walls.

5For a standard residential plot of typical dimensions, what is the minimum rear setback distance required under Dhaka building regulations?

A.1.0 meter

B.1.5 meters

C.2.0 meters

D.3.0 meters

Explanation: Under the Dhaka Mohanagar Imarat Nirman Bidhimala 2008, the minimum rear setback required for a standard residential building is 2.0 meters. This space is necessary to ensure adequate ventilation, light, and privacy between adjacent plots, as well as to allow access for maintenance and emergency services. Side setbacks are typically smaller (1.25 meters or 1.0 meter for small plots).

6What is the absolute minimum road width required for a plot to be eligible for building approval under the rules of RAJUK in Dhaka?

A.2.4 meters (8 feet)

B.3.0 meters (10 feet)

C.3.65 meters (12 feet)

D.4.5 meters (15 feet)

Explanation: According to RAJUK rules, the minimum width of the access road serving a plot must be at least 3.0 meters (10 feet) for any building plan to be approved. If the existing road is narrower, the land owners must set back their boundaries and surrender land to achieve the required width before approval can be granted. This rule prevents fire hazards and accessibility blockages.

7What does the term Maximum Ground Coverage (MGC) refer to in Bangladesh building bylaws?

A.The maximum depth of the foundation excavation below the natural ground level

B.The maximum percentage of the total plot area that can be covered by the building footprint on the ground

C.The maximum area of paved parking allowed on the ground level of a plot

D.The total height of the building relative to the ground surface level

Explanation: Maximum Ground Coverage (MGC) is the maximum percentage of the total plot area that can be covered by the footprint of the building. MGC constraints ensure that a significant portion of the plot remains unbuilt as open space for landscaping, rainwater absorption, light, and ventilation. MGC varies based on plot size and occupancy type.

8How do FAR and Maximum Ground Coverage (MGC) work together to determine a building's height and shape?

A.MGC determines the total floor area, while FAR determines the building height

B.FAR dictates the total built volume, while MGC limits the horizontal footprint, naturally forcing the building to go vertical to utilize the full FAR

C.Both FAR and MGC restrict the height of the building based on the cardinal direction of the entrance road

D.MGC is only applicable to basement design, while FAR is applied to the super-structure

Explanation: FAR determines the total allowed floor area across all floors, while MGC limits the ground footprint of the building. By limiting the horizontal footprint, MGC prevents the developer from covering the entire plot with a low-rise structure, forcing the building to go vertical (adding more floors) to fully utilize the total floor area allowed under FAR.

9If a developer has a plot of 5,000 square feet and the allowable FAR is 3.5, what is the maximum total floor area (excluding permitted exemptions) that can be built?

A.12,500 square feet

B.17,500 square feet

C.20,000 square feet

D.22,500 square feet

Explanation: The maximum total floor area is calculated as: Plot Area * FAR. Therefore, 5,000 sq ft * 3.5 = 17,500 sq ft. This is the total gross floor area allowed across all upper levels of the building, subject to further layout restrictions such as setbacks and MGC.

10What is 'Mandatory Open Space' under the Dhaka Mohanagar Imarat Nirman Bidhimala 2008?

A.The land dedicated to municipal parks outside the plot boundaries

B.The unbuilt open area that must be left inside the plot boundaries as setbacks and courtyards

C.The area reserved exclusively for public roads and pathways

D.The roof terrace of the building which must remain open to the sky

Explanation: Mandatory Open Space refers to the unbuilt areas within the plot boundaries (such as front, rear, and side setbacks, and internal courtyards) that must remain open to the sky. The bylaws prohibit constructing permanent structures in these spaces to guarantee natural light, ventilation, and emergency access.
