Based on actual 2026 market rates in Al Khobar and the Eastern Province: the economy tier runs SAR 80–150/m² (furniture layout plan and 2D visualization), the mid tier — the most requested — runs SAR 150–350/m² (full design identity, electrical and mechanical drawings, and 3D visualization), and the luxury tier starts at SAR 350/m² and up (fully custom designs and comprehensive execution supervision).

Engineering supervision is an ongoing on-site follow-up service provided by an independent engineer or consulting office representing the owner’s interests (not the contractor’s), to confirm the project is being built according to approved drawings, complies with the Saudi Building Code, uses the agreed materials at the correct quality, and stays on schedule and budget. Unlike design, supervision is a continuous service that can run from several months to over a year depending on the project’s size.

The steps to issue a building permit through Balady include: authorizing a licensed engineering office to begin the process, preparing architectural and structural drawings and submitting them to a technical inspection company to confirm compliance with the Saudi Building Code, municipal approval of the drawings, appointing a supervision office and an executing contractor, issuing the mandatory insurance policy, then paying the municipal fees through the official fee calculator to issue the permit electronically.

Soil testing identifies the soil type and its load-bearing capacity, helping the structural engineer determine the right foundation type and depth. Skipping this test can lead to serious structural problems later, such as settlement or cracking in the building. That’s why starting construction without a soil test is never recommended.

Choosing a contractor shouldn’t be based on price alone — an unusually low price can sometimes mean missing line items or an underestimated project. It’s best to collect quotes from several contractors and compare them carefully. We also recommend visiting the contractor’s previous projects to verify the quality of their work, ideally accompanied by a qualified engineer.

A contract isn’t just a formality — it’s a document that protects all parties. It should clearly define the scope of work, specifications, timeline, payment schedule, penalties, and any excluded items. Don’t rely on verbal agreements, since small overlooked details can later turn into major financial disputes.

Many construction mistakes happen during the execution phase, most often caused by unplanned changes, weak supervision, or rushing the work. One of the most serious errors is modifying structural elements — such as relocating columns or removing beams — without consulting the engineer. The golden rule here: any structural change must go back to the engineering office first.
