Q. 1 Architectural Design
Difficulty: Easy (1 Mark)
In urban planning and municipal building bye-laws, what does 'Floor Area Ratio' (FAR) or 'Floor Space Index' (FSI) define?
A
The ratio of the total gross covered floor area of all building floors combined to the total gross area of the building plot ($FAR = Total\ Covered\ Floor\ Area / Plot\ Area$)
✓ Correct
B
The ratio of carpet area to wall thickness
C
The cost of land divided by the cost of cement
D
The ratio of bedroom area to bathroom area
💡 Step-by-Step Explanation & Concept Rationale
Floor Area Ratio (FAR) or Floor Space Index (FSI) regulates built volume and urban density: $FAR = \text{Total Gross Floor Area of All Stories} / \text{Gross Plot Area}$. For example, on a 1,000 m² plot with an allowable FAR of 2.0, the total permitted gross floor area across all floors is 2,000 m².
Q. 2 Architectural Design
Difficulty: Easy (1 Mark)
In building zoning regulations, what is 'Maximum Ground Coverage'?
A
The maximum percentage of the total plot area that can be occupied by the ground-level building footprint, leaving the remaining open area for setbacks and landscaping
✓ Correct
B
The thickness of the foundation concrete slab
C
The area of turf grass required on the lawn
D
The total depth of underground parking
💡 Step-by-Step Explanation & Concept Rationale
Ground Coverage is the proportion of the plot area covered by the building footprint: $(\text{Footprint Area} / \text{Plot Area}) \times 100\%$. If maximum ground coverage is 60% on a 500 sq. yd. plot, the building footprint cannot exceed 300 sq. yd., preserving 40% open space.
Q. 3 Architectural Design
Difficulty: Easy (1 Mark)
What is the primary regulatory purpose of requiring mandatory 'Setbacks' (front, rear, and side yards) in municipal building bye-laws (e.g., CDA, LDA, SBCA)?
A
To ensure adequate access for natural light, cross-ventilation, privacy between neighbors, rainwater percolation, and fire emergency apparatus access around the building
✓ Correct
B
To provide space for street vendors
C
To mark boundaries for electrical high-tension pylons
D
To allow underground mining
💡 Step-by-Step Explanation & Concept Rationale
Setbacks are open statutory clear zones between the property boundary line and the external building wall. They guarantee daylight access, ventilation, acoustic separation, and space for firefighting ladders and hose access during emergencies.
Q. 4 Architectural Design
Difficulty: Easy (1 Mark)
In Kevin Lynch's classic urban design theory ('The Image of the City', 1960), what are the five basic physical elements people use to perceive and form mental cognitive maps of a city?
A
Paths, Edges, Districts, Nodes, and Landmarks
✓ Correct
B
Roads, Bridges, Tunnels, Walls, and Houses
C
Concrete, Steel, Glass, Timber, and Brick
D
Cars, Buses, Trains, Airplanes, and Bicycles
💡 Step-by-Step Explanation & Concept Rationale
Kevin Lynch demonstrated that urban legibility and mental mapping rely on five spatial elements: (1) Paths (channels of movement), (2) Edges (linear boundaries), (3) Districts (medium-to-large sections with identifiable character), (4) Nodes (strategic focal junction points), and (5) Landmarks (prominent visual reference points).
Q. 5 Architectural Design
Difficulty: Easy (1 Mark)

✓ Correct
B
1 : 2 (50% slope)
C
1 : 5 (20% slope)
D
1 : 1 (45 degrees)
💡 Step-by-Step Explanation & Concept Rationale
Under BCP Accessibility Guidelines and international ADA standards, the maximum allowable slope for an accessible wheelchair ramp is 1:12 (8.33%). The maximum continuous rise permitted without an intermediate horizontal rest landing (minimum 1.5 m long) is 750 mm (30 in / 9 meters run).
Q. 12 Architectural Design
Difficulty: Medium (1 Mark)
What is the minimum clear opening width required for entrance doors to ensure full wheelchair accessibility under the BCP Accessibility Code?
A
850 mm to 900 mm (34 to 36 inches)
✓ Correct
B
500 mm
C
600 mm
D
1,500 mm
💡 Step-by-Step Explanation & Concept Rationale

✓ Correct
B
Hallway → Elevator → Street
C
Window → Fire Escape → Alley
D
Room → Balcony → Roof
💡 Step-by-Step Explanation & Concept Rationale
A compliant Means of Egress comprises three sequential parts: (1) Exit Access (travel path leading from occupied room to the entrance of an exit), (2) Exit (fire-rated separation providing a protected travel path, e.g., an enclosed 2-hour fire stair), and (3) Exit Discharge (path connecting exit directly to a public way outside).
Q. 14 Architectural Design

Under Life Safety Codes, any exit door serving a room or space with an occupant load exceeding how many persons must swing outward in the direction of exit travel?
A
50 persons
✓ Correct
B
5 persons
C
500 persons
D
1,000 persons
💡 Step-by-Step Explanation & Concept Rationale
Life safety codes universally require exit doors to swing in the direction of egress travel when serving an occupant load of 50 or more persons (or any high-hazard occupancy) to prevent crowds from pressing against inward-opening doors during panicked evacuations.
Q. 15 Architectural Design
Difficulty: Easy (1 Mark)
In building egress design, what is 'Panic Hardware' installed on exit doors?
A
A horizontal push bar mounted across the door that unlatches the door instantly when pushed with light bodily pressure without requiring turning of knobs or keys

B
2 hours
C
6 months
D
Exactly 3 days
💡 Step-by-Step Explanation & Concept Rationale
Under PPRA Rule 12, the procuring agency must give a minimum response time of at least 15 calendar days from the date of publication in the press for domestic tenders, and at least 30 days for international tenders.
Q. 21 Architectural Design
Difficulty: Easy (1 Mark)
What type of construction contract fixes a single total lump-sum price for the entire scope of work, placing the risk of cost overruns primarily on the contractor?
A
Lump Sum (Stipulated Sum) Contract
✓ Correct
B
Cost-Plus-Percentage Contract
C
Time and Materials Contract
D
Daywork Contract
💡 Step-by-Step Explanation & Concept Rationale
In a Lump Sum contract (FIDIC Red/Silver Book equivalent), the contractor agrees to deliver the complete specified project for a single fixed sum. The contractor absorbs the financial risk of price fluctuations unless formal client-directed variation orders are issued.
Q. 22 Architectural Design
Difficulty: Medium (1 Mark)
In building project scheduling, what is the 'Critical Path' in the Critical Path Method (CPM)?
A
The longest continuous sequence of dependent project activities that determines the shortest possible total duration to complete the project, with zero total float (slack)
✓ Correct
B
The shortest hallway in a building plan
C
The emergency exit route from a construction site
D
The electrical conduit path on a ceiling
💡 Step-by-Step Explanation & Concept Rationale
The Critical Path represents the longest sequence of dependent tasks from project start to finish. Any delay to any task on the critical path directly delays the overall project completion date because critical path activities have zero float (slack = 0).
