Design

At Anfra Design, you get comprehensive, optimised structural design for a variety of construction projects. We offer design services without the obligation to commission the project with us, but if you wish, we can manage the entire project from start to finish.

We are a specialist in concrete structural design. As a flexible operator if necessary, we can also draw up plans for the same project for the client other structures that are closely related. We also have strong expertise in the design of bridges and other bridge structures, structural steel engineering and geotechnical engineering. Our strength lies in our ability to manage complexity!

Customers have been very satisfied with our design. Based on customer satisfaction surveys, the NPS score for 2024 is as high as 87!

Optimising the design

Planning is key to managing project costs. Although design usually accounts for only a few percent of the total cost, its impact on the final cost is significant.
Most of the production costs of a project are determined at the design stage. Our expertise focuses on cost-effective design, combining feasible solutions and minimising environmental impact, while enabling smooth and economical implementation.
We check the optimisation potential of all our sites before production, whether they are designed by us or by another design agency. If there is a potential for savings, we offer our client the possibility of optimising the structures before implementation.

The optimisation of the plans will consider, among other things, the following aspects:

  • the technical suitability of the structures for production
  • the efficiency of the sizing of structures
  • optimisation of concrete strength and stress classes
  • optimising steel quantities and installation techniques
  • optimising the strengths of structures
  • the possibility of using fibre concrete
  • optimisation of the number of piles


The review results in cost savings of up to 10-30 % in material and labour. The actual work on site could be reduced by up to 50 %. Where potential savings are found, there is no need to be timid about redesign. In most cases, the benefits are many times greater than the additional cost of the design.

Structural design

Our design unit has its origins in the design of concrete structures. So we have a very strong and long experience in this field, with hundreds of projects, both large and small. Our passion is to constantly evolve in our work and that is why we have not been satisfied with a traditional design approach. We also design steel structures, if required, which are closely linked to the rest of our design package.

Anfra Design pays close attention to production engineering aspects such as casting sequences, moulds and similar factors at the design stage, which sets us apart from traditional approaches. Our designers have a strong production background and we work closely with Anfra's production. Our designs always incorporate cost-saving production solutions that have a big impact on overall cost-effectiveness.

Design plays a crucial role in the environmental impact of concrete construction. Anfra Design is responsibly committed to always designing for our environment, minimising the impact on emissions through efficient use of materials and the development and use of new greener solutions.

Design of infrastructures

In infrastructure construction, we design all kinds of structures for the built environment. Our particular strengths include the design of bridges and other road structures, from preliminary design to construction planning. We use our own production facilities for the design. Through this cooperation we ensure optimal and overall economically efficient structures on a site-specific basis. We also implement projects using the design and build (ST) model.

  • Bridges
  • Slabs
  • Retaining walls
  • Water and coastal structures
  • Noise barriers on roads and railways


We typically design infrastructure for projects in industry, private roads, municipalities, ELY centres and the Finnish Transport Agency.
We also carry out reviews of already planned sites for structural improvements and upgrades. If necessary, we can offer, for example, an alternative bridge structure with plans for a bridge on a private road, in addition to the client's design, if we find it to be a more economically and technically efficient solution.

Our designers have more than 25 years of experience in designing bridges and other engineering structures and managing design projects. Our certifications include:

  • FISE Designer of Concrete Structures, difficulty class exceptionally difficult
  • FISE Design of steel structures, Very demanding


With our strong expertise, we implement, among other things:

  • Preliminary studies and comparisons of alternatives
  • General and preliminary designs
  • Construction design
  • Carrying capacity analysis for bridges
  • Dimensioning the bridge openings for bridges over waterways
  • Consultancy services


In addition, we also provide services such as:

  • Permits under the Water Act, request for statements
  • Measurements and soil surveys

What is Anfra Design?

Anfra Design is an independent unit within Anfra. We design the majority of Anfra's concrete and civil engineering projects, but we also offer our design services for projects where Anfra is not the contractor.

  • Thirteen highly experienced designers, including FISE qualifications
  • Computer model-based design, illustrative and easy-to-read plans
  • A new approach to design that takes into account the production phase
  • Design ideology to minimise environmental impacts
  • Years of experience working on international projects
  • Also complete or partial redesign of projects for the benefit of the client


The focus of our design work is always on the beneficial impact on the overall project economics!
