SCE Saudi Building Code 4

Question 1

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

Accepted Answer

35 MPa with a maximum w/c ratio of 0.45

Answer

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.

Question 2

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

Accepted Answer

Corrosion through painting, galvanizing, or other approved coating systems

Answer

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.

Question 3

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

Accepted Answer

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

Answer

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.

Question 4

SBC requirements for elevator installation in buildings include:

Accepted Answer

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

Answer

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.

Question 5

The SBC requirement for parking in Saudi buildings typically mandates:

Accepted Answer

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

Answer

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.
