Comprehensive and Detailed Explanation From Exact Extract:

Rooms such as medical treatment or healthcare spaces require wall finishes that are smooth, scrubbable, and water-resistant to maintain hygiene and allow for regular cleaning and disinfection.

Tight, sealed seams (A) and absence of fissures (B) are important but part of broader requirements.

The key is surfaces that can withstand cleaning agents and moisture exposure without damage.

This ensures compliance with healthcare facility codes and infection control.

Comprehensive and Detailed Explanation From Exact Extract:

As building height increases, wind pressures acting on the building surfaces increase because wind speed generally increases with elevation due to reduced friction from ground features (A).

Additionally, taller buildings experience larger lateral displacements (drift), requiring more complex structural systems and stiffer frames to control excessive drift for occupant comfort and structural safety (E). This requirement significantly increases structural costs.

Dead load (B) and live load (D) increase with stories but do not increase exponentially or primarily affect wind resistance costs.

Snow and rain loads (C) mostly affect the roof, not height-related wind loads.

Choice of cladding materials (F) impacts cost but is not a primary reason for exponential wind resistance cost increases.

Wind pressure on a building's roof can be either positive (pressure pushing down on the surface) or negative (suction or uplift). The distribution of pressure depends largely on wind direction relative to the building geometry and roof slope.

Option C: When wind strikes the roof perpendicular to the ridge with slopes between 30 and 45 degrees, the wind creates a positive pressure on the windward side of the roof. This is because the air impinges directly onto the sloped surface, pushing downward and exerting positive pressure. The leeward side of the roof, by contrast, experiences negative pressure (suction). This condition is well documented in ASCE 7 and reflected in the IBC (International Building Code) wind load provisions.

Option A: Wind parallel to the long side with a flat roof typically causes mostly negative pressures (suction) on the roof, not positive pressures, because the airflow accelerates over the roof surface.

Options B and D: At lower roof slopes (like 15 degrees) or when the wind is parallel to the ridge with moderate slopes, the roof usually experiences suction (negative pressure) rather than positive pressure. The flatter or more parallel the surface is relative to wind flow, the more suction effects dominate.

Positive wind pressure on roofs is important for structural design because it influences the design of roofing systems, connections, and overall structural loads. Understanding when and where positive pressure occurs ensures proper anchorage and prevents failures due to uplift or overturning forces.

Comprehensive and Detailed Explanation From Exact Extract:

Redesigning a building for high seismic risk typically requires enhanced lateral force-resisting systems:

Ductile moment-resisting frames (B) involve special detailing for energy dissipation and ductility, requiring larger and more complex reinforcement, resulting in high construction costs.

Adding shear walls (A) or braced frames (C) can be more economical lateral systems but may affect architectural layouts.

Bracing a soft story (D) is a mitigation technique and usually less costly than complete frame redesign.

Therefore, ductile moment-resisting frame redesign is the costliest option.

Comprehensive and Detailed Explanation From Exact Extract:

Pervious paving allows water to infiltrate through surfaces, reducing runoff and preventing erosion and surface water accumulation on site. It is an effective stormwater management technique suited to infill sites where space is limited.

A catchment area (B) collects water but does not prevent erosion or surface water by itself.

Horizontal overhangs (C) provide shading and weather protection but do not affect surface water runoff.

NCARB PPD guidelines emphasize permeable surfaces as key components of sustainable site design to manage stormwater onsite.
