When starting a new construction project, understanding the cost of engineering drawings is one of the first concerns for project owners. You may be surprised by the significant price variation between engineering offices, raising the question: What factors actually determine this cost?
Investing in well-studied, high-quality drawings may increase the initial "engineering design" cost, but in every case it represents significant savings for the owner during the construction phase itself.
Engineering offices in the market generally use several approaches to price their projects:
The most common method in the Saudi market, especially in the residential sector. A set price per square meter of built area is established, covering architectural, structural, and basic electrical and plumbing drawings for permit issuance.
Some offices study the client's requirements and offer a fixed lump sum for the complete package (common for certain palaces or custom residential villas).
For large commercial projects and BIM modeling work, the project is internally assessed by estimating the professional hours needed for each discipline. This provides a more professional, realistic, and fair price that reflects the actual scope of work required.
Price differences don't arise from nothing — the quote is a direct reflection of the effort invested, additional services, and level of drawing detail. Key factors that increase cost include:
A carefully engineered structural design takes the engineer significantly more time to test various options and develop solutions that provide safe and adequate quantities of concrete and rebar for the owner — without over-engineering. There are many documented cases where "very cheap, rushed designs" cost the owner thousands of riyals in wasted steel during construction.
A basic plan for obtaining a building permit differs greatly in effort and price from a comprehensive architectural design that includes detailed BOQ & Quantity Takeoff schedules, Shop Drawings, BIM Modeling Services, facade details, and interior design packages.

Offices that use BIM (Building Information Modeling) 3D technology deliver significant added value through system coordination and early clash resolution — before issues manifest on site and cause unexpected costs for the owner. These smart models require time and effort to prepare, which naturally reflects in the service cost.
