Comprehensive and Detailed Explanation From Exact Extract:
For stairs serving 100 occupants, building codes such as IBC require a minimum clear width of 44 inches to accommodate occupant egress.
36 inches is typical minimum for stairs serving smaller occupant loads.
Wider widths like 48 or 60 inches are required for higher occupant loads.
Handrails and projections may reduce nominal width but are not included in minimum clear width measurements.

Comprehensive and Detailed Explanation From Exact Extract:
Bus duct systems with tap boxes offer modular, flexible electrical distribution capable of handling high loads and allowing easy future expansions with minimal disruption and cost.
Paralleled wires (A, B) increase complexity and are less flexible.
Single large conductors (C) are limited in expansion.
Bus ducts optimize installation speed, scalability, and cost in commercial building retrofits.

Explanation:
The solar shade should be installed within the ceiling recess above the curtainwall, behind the horizontal soffit-specifically in the void space between the top of the curtainwall glazing and the structural ceiling soffit (the shaded area immediately above the curtainwall glass in the section).

Comprehensive and Detailed Explanation From Exact Extract:
Using vertical steel trusses in the external walls (B) allows for efficient lateral load resistance by creating a stiff, braced perimeter that resists wind and seismic forces with less material compared to internal bracing or heavy columns.
Heavy steel columns and rigid connections (A) require more steel and complex joints, increasing cost.
Light steel columns with flexible connections (C) provide less stiffness and require more members.
Internal steel trusses (D) reduce usable space and complicate architectural layouts.
External vertical trusses optimize structural efficiency and cost, as supported in NCARB PPD guidelines for high-rise construction.

Comprehensive and Detailed Explanation From Exact Extract:
Electric heating systems are compact, have low initial installation costs, and can be easily zoned with individual controls. They provide rapid response to temperature changes, making them suitable where space is limited and quick control is desired.
Hydronic systems have slower thermal response and require piping infrastructure.
Forced air systems need ductwork and are less compact.
Combination systems increase complexity and cost.
