Modern construction projects require careful planning and technical expertise to ensure that buildings and structures are both safe and functional. Before actual construction can begin, the project’s technical solutions must be developed and properly designed. One of the most important roles in this process is the structural engineer.
But what exactly does a structural engineer do in construction, and how important is the role for the execution of a construction project?
In this article, we go through the structural engineer’s responsibilities, tasks, and expertise, as well as how the role contributes to creating safe and feasible technical solutions in construction projects.

The Structural Engineer’s Role in Design and Technical Solutions

The structural engineer primarily works during the design phase of construction projects and is responsible for developing technical solutions for the building’s load-bearing structures. This involves designing and dimensioning different parts of the structure so that the building can withstand the loads and stresses it will be exposed to throughout its lifespan.
The work may include structures made of:

• Concrete
• Steel
• Timber
• Prefabricated elements

The structural engineer ensures that these structures comply with applicable standards and technical requirements, while also making sure the solutions can actually be implemented during construction.

Structural Design and Dimensioning

One of the structural engineer’s most central responsibilities is dimensioning the building’s load-bearing components. This means calculating the forces and loads the structure must be able to withstand.
Examples of such loads include:

• Self-weight of the building structure
• Live loads from people and equipment
• Wind loads
• Snow loads
• Dynamic loads in certain structures

Through advanced calculations and analyses, the structural engineer ensures that the structure is stable, safe, and compliant with applicable regulations.

Preparation of Technical Documentation

An important part of the structural engineer’s work is preparing technical documentation used throughout the project. These documents form the basis for both the design process and the construction phase.
Technical documentation may include:

• Structural drawings
• Calculation reports
• Detailed drawings
• Technical descriptions

These documents are used by contractors, project managers, and other stakeholders to understand how the structure should be built.

Collaboration with Other Disciplines

Construction projects often involve several technical disciplines that must be coordinated during the design phase. Structural engineers therefore work closely with other professionals in the project, such as:

• Architects
• MEP designers
• Geotechnical engineers
• Project managers

Through this collaboration, it is ensured that the building’s technical solutions work together with the project’s architectural and technical requirements.

Collaboration Between Design and Construction

Although the structural engineer’s work mainly takes place during the design phase, collaboration often continues during construction. Questions may arise on-site regarding how the structure should be executed in practice.
This may involve:

• Clarification of structural drawings
• Technical questions from the contractor
• Adjustments to structural solutions
• Handling changes in the project

Through continuous dialogue between design and construction teams, the structural engineer helps ensure that technical solutions work in practice and that any issues are resolved efficiently.

Quality and Safety in Structural Design

The structure is one of the most critical parts of a construction project because it affects both the building’s safety and lifespan. Structural engineers therefore carry significant responsibility for ensuring that technical solutions meet high standards of quality and safety.
This includes:

• Following applicable building codes and standards
• Verifying calculations and dimensioning
• Ensuring the structure is stable and safe
• Contributing to the project’s technical quality

Through careful analyses and inspections, structural engineers can minimize risks in the structure.

Digital Tools and BIM in Design

Digitalization has transformed work within design and construction engineering. Today, many structural engineers use advanced digital tools for modeling and analysis.
Examples of such tools include:

• BIM models
• Structural analysis software such as Tekla Structural Designer and StruSoft FEM-Design
• Digital coordination platforms

These tools make it possible to visualize the structure, analyze technical solutions, and improve coordination between different disciplines in the project.

Experience and education

Most structural engineers have a technical education within construction or civil engineering. Common educational paths include:

• Master of Science in Civil Engineering
• Bachelor of Science in Construction Engineering
• Technical education specializing in structural engineering

The education provides knowledge in areas such as structural mechanics, strength of materials, and construction technology.
In addition to formal education, experience from design work and construction projects is often essential for developing within the role.

Personal qualities in the role

Working as a structural engineer requires several important qualities.
Since the work often involves technical analysis and problem-solving, a structural engineer needs to be:

• Analytical and detail-oriented
• Structured in their work
• Solution-oriented
• Communicative when collaborating with other disciplines

The ability to combine technical analysis with practical understanding of construction processes is often crucial in the role.

Courses and professional development

Continuous professional development is important for structural engineers because technical methods and regulations evolve over time.
Examples of training that can strengthen competence include:

• Advanced courses in structural engineering and dimensioning
• Training in BIM and digital design
• Courses in building codes and standards
• Specialization in different construction materials

By combining technical knowledge, practical experience, and ongoing education, structural engineers can contribute to developing safe and efficient solutions in construction projects.

Challenges in the Role of a Structural Engineer

Working as a structural engineer also involves several challenges. Construction projects are often complex, and technical solutions must work together with both architectural requirements and construction conditions.
Common challenges may include, for example:

• Finding technical solutions that are both safe and cost-effective
• Coordinating the structure with other technical disciplines
• Managing changes in the project design
• Ensuring the structure works during construction

Handling these challenges requires both technical expertise and strong collaboration skills.
