What Is a structural execution design and why shouldn’t it be skipped?

Date of the last update: 21.05.2025

A structural execution design is a crucial stage in the construction process. It serves as the foundation for actual on-site works, enabling contractors to follow precise guidelines. Skipping this phase can result in costly mistakes, project delays, and misunderstandings between parties involved in the construction process.

At METIB, we have been preparing detailed structural execution designs for both domestic and international markets for years, providing our clients with comprehensive support and the highest quality of documentation.

What does a structural execution design include?

The execution design is significantly more detailed than the building permit design. It includes a full set of technical drawings, structural details, material specifications, static calculations, and assembly instructions. All of these components are necessary for the contractor to accurately reflect the design assumptions on site.

At METIB, we prepare execution documentation using state-of-the-art BIM technology, which allows for precise planning and early detection of potential conflicts at the design stage.

Execution design vs. building permit design – what’s the difference?

The building permit design is a formal document required to obtain planning permission. It includes general structural assumptions such as architectural layouts, estimated load-bearing parameters, element spacing, and main material guidelines. While essential for legal and administrative purposes, it does not provide sufficient technical detail for actual construction works.

The execution design follows as the next, more advanced phase. Engineers and structural designers develop a complete working documentation set – including technical drawings, construction details, structural calculations, and mounting instructions. This comprehensive documentation allows contractors to execute the project precisely and helps investors better control budgets and timelines.

A well-prepared execution design helps avoid interpretation errors and costly modifications during construction. At METIB, we ensure all our execution designs are compliant with relevant standards and easy for contractors to interpret. See our full structural design offer to learn more.

Why Is the execution design crucial for a construction project?

From an investor’s perspective, an execution design is a guarantee that the project will proceed as intended. For the contractor, it serves as a clear roadmap, helping avoid costly on-site errors. A well-prepared execution design reduces the risk of rework, shortens the construction timeline, improves logistics and assembly planning, and supports seamless interdisciplinary collaboration.

At METIB, every project undergoes detailed verification and quality control before it is delivered to the client.

Who prepares the execution design and when?

Execution designs are prepared by a qualified design office with the necessary structural engineering licenses. This phase typically follows the building permit design and provides the foundation for contractor bids and project implementation.

At METIB, we offer full support throughout every stage of the investment process – from concept development and technical documentation to shop drawings.

How much does an execution design cost?

The cost of an execution design depends on several factors, including the type and scale of the building, structural complexity, scope of calculations, and level of detail required. For simpler projects like a single-family home, the cost may start from a few thousand PLN. For large industrial or multi-storey commercial buildings, the price can range from tens to even hundreds of thousands of PLN.
