Saudi Building Code Flashcards

SBC 302 (Structural - Concrete) specifies the minimum compressive strength for structural concrete exposed to sulphate-rich soil as:

Answer: 35 MPa with a maximum w/c ratio of 0.45

For moderate to severe sulphate exposure (common in Saudi Arabia), SBC requires minimum 35 MPa concrete with w/c ≤ 0.45 and Type V (sulphate-resistant) cement to ensure durability against chemical attack.

SBC requires that all structural steel in Saudi Arabia be protected against:

Answer: Corrosion through painting, galvanizing, or other approved coating systems

Saudi Arabia's coastal humidity, inland sandstorms, and industrial environments require comprehensive corrosion protection for structural steel through hot-dip galvanizing, epoxy coatings, or other approved systems.

What is the SBC requirement for waterproofing basements in Saudi Arabia?

Answer: Comprehensive waterproofing membrane system with drainage, especially in areas with high water tables

SBC requires proper waterproofing of below-grade construction, including membranes, drainage boards, and dewatering systems. Rising water tables in many Saudi cities make this critical for building longevity.

SBC requirements for elevator installation in buildings include:

Answer: Mandatory elevators in buildings over a specified number of stories, with fire service features for high-rises

SBC requires elevators in buildings over certain heights, accessible elevators in public buildings, fire service (firefighter) elevators in high-rises, and specific shaft fire ratings and ventilation requirements.

The SBC requirement for parking in Saudi buildings typically mandates:

Answer: Minimum parking spaces based on building type, area, and occupancy with specific accessibility provisions

SBC and municipal regulations specify minimum parking ratios (e.g., 1 space per residential unit, 1 per 40m² for offices) with requirements for accessible spaces, dimensions, aisle widths, and ventilation for enclosed garages.

SBC requires building envelope thermal performance testing using:

Answer: U-value calculations and compliance with maximum allowable thermal transmittance values

SBC mandates that building envelope components (walls, roofs, windows) meet maximum U-value requirements through calculations or testing, ensuring thermal performance under Saudi Arabia's extreme heat conditions.
