Which construction type is characterized by exterior walls that support the weight of the structure and interior floors and roof?

Correct Answer

C) Masonry bearing wall construction

Masonry bearing wall construction uses exterior masonry walls (brick, stone, concrete block) to support the structural loads of floors and roof. In contrast, frame construction uses an internal skeleton of wood or steel to carry structural loads.

Answer Options
A
Steel frame construction
B
Post and beam construction
C
Masonry bearing wall construction
D
Wood platform frame construction

Why This Is the Correct Answer

Masonry bearing wall construction is characterized by thick exterior walls made of brick, stone, or concrete block that serve as the primary load-bearing elements. These walls directly support the weight of interior floors, roof systems, and any upper stories, transferring all structural loads down to the foundation. The masonry walls function as both the building envelope and the structural support system, eliminating the need for an internal frame. This construction type was common in older commercial and residential buildings before modern frame construction became prevalent.

Why the Other Options Are Wrong

Option A: Steel frame construction

Steel frame construction uses an internal skeleton of steel beams and columns to carry structural loads, with exterior walls serving primarily as cladding rather than load-bearing elements.

Option B: Post and beam construction

Post and beam construction relies on vertical posts and horizontal beams as the primary structural system, with walls typically serving as infill rather than load-bearing components.

Option D: Wood platform frame construction

Wood platform frame construction uses wood studs, plates, and joists as the structural framework, with exterior walls being part of the frame system rather than solid load-bearing masonry.

BEAR the WEIGHT

Remember 'Masonry BEARS the WEIGHT' - the thick masonry walls literally bear (carry) the weight of the entire structure from exterior to interior, like a strong bear carrying a heavy load on its back.

How to use: When you see questions about exterior walls supporting structural weight, think of the bear carrying the load and immediately identify masonry bearing wall construction as the answer.

Exam Tip

Look for key phrases like 'exterior walls support the weight' or 'walls carry structural loads' - these almost always point to masonry bearing wall construction rather than frame systems.

Common Mistakes to Avoid

  • -Confusing frame construction with bearing wall construction when exterior walls are mentioned
  • -Assuming all masonry buildings use bearing wall construction when some use masonry veneer over frame
  • -Not recognizing that bearing walls limit interior renovation possibilities, affecting functional utility

Concept Deep Dive

Analysis

This question tests understanding of structural systems in building construction, specifically how different construction types distribute and support structural loads. The key distinction is between bearing wall systems where exterior walls carry the structural load versus frame systems where an internal skeleton supports the structure. Understanding load-bearing elements is crucial for appraisers as it affects building durability, maintenance costs, and overall value. Different construction types also have varying lifespans, insurance considerations, and renovation limitations that impact property valuation.

Background Knowledge

Appraisers must understand different construction types because they significantly impact a property's durability, maintenance requirements, and market value. Load-bearing wall systems versus frame construction also affects renovation possibilities and seismic performance, which are important valuation considerations.

Real-World Application

When appraising older commercial buildings or historic properties, identifying masonry bearing wall construction helps explain higher maintenance costs, limited renovation flexibility, and the need for specialized structural assessments, all of which impact market value and comparability analysis.
