The Saudi Building Code and Its Effect on Cost
The Saudi Building Code is a binding set of technical requirements covering structure, fire, energy efficiency, electrical, mechanical and plumbing works in buildings.
What the code is
The code is a unified technical reference setting the minimum acceptable level for the safety and performance of buildings. It is issued in separate parts, each covering a discipline: loads and structural design, fire protection, energy efficiency and insulation, electrical, mechanical and plumbing works, plus a part dedicated to small residential buildings. Compliance is a condition of approving the drawings.
Where its cost shows up
In three places specifically: thermal insulation and window performance requirements, which raise the cost of the external envelope and lower the running bill afterwards; fire protection requirements — escapes, sprinklers and alarms in the buildings that need them; and structural design requirements, which feed through into member sizes and reinforcement quantities.
Who checks compliance
The designing engineering office is responsible for the drawings’ compliance, the municipal review verifies it before the permit is issued, and the engineering supervision follows it during execution. The contractor is part of the equation too, because substituting a cheaper material can take the building out of compliance and hold up handover.
How a contractor handles it in practice
Read the specifications tied to the code before pricing, not after: the type of insulating block, the insulation thicknesses, the glazing specification, the fire system requirements. Pricing these items at the lowest specification and then discovering a higher one at approval is among the most common ways a margin is eroded.
Worked example
A villa was priced on ordinary block with direct external paint; it then emerged that the specification required insulating block and a defined insulation thickness on the envelope. The difference exceeded SAR 60 per square metre of external wall — an item that reading the specifications before submitting the offer would have caught.
FAQ
Is the code binding on small private buildings?
Yes, and there is a part aimed at small residential buildings that simplifies the requirements to suit them without giving up the safety and performance limits.
Does the code raise cost or lower it?
It raises the initial construction cost on envelope and fire items, and lowers the operating cost over the building’s life. The correct reading is economic across the period of use, not at the moment of building alone.
How do I price an unfamiliar item the code imposes?
Analyse its rate from its components and ask suppliers for actual offers against that exact specification, because the price gap between two specifications that sound similar can be very large.
