Ivan Kvochka brings to the GRIZZONI production hall something that cannot be learned only from the manual: 30 years of experience in wood and construction, thousands of work hours with wood and a sense of material. It began in a time when a large part of the work was done manually and the accuracy depends primarily on the master's experience. These foundations have been transferred to modern production, where today the complete manufacturing process of prefabricated panels is managed from the first cutting of the KVH grenole to the final control of the finished partition.

Ivan is the person colleagues turn to when they are unsure. He understands wood and how it behaves under different moisture levels, temperatures and loads. Every panel leaving the workshop passes his inspection: he checks dimensions, frame squareness and joint quality. Small deviations can add up when components are joined, making assembly on site more difficult, so he insists on accuracy from the production stage.

Over 30 years in the industry, Ivan has worked on many projects and in a range of roles. He has experience with different timber structures and has seen technologies and materials develop, giving him a practical understanding of what works. This depth of experience makes him a valued team member. As production foreman, he helps define and maintain GRIZZONI’s quality standard every day.

Tomáš Jerdonek has more than three decades of hands-on construction experience, solving problems on site and ensuring that houses are built as designed. He combines extensive practical knowledge with the ability to lead a team and maintain consistent standards of workmanship.

As GRIZZONI’s lead assembly foreman, Tomáš manages the entire process from the panels arriving on site to the completed house being handed over. He organises the assembly team, coordinates each stage and personally checks critical details: the foundation slab, panel installation, roof structure, sheathing and insulation. He knows that following the correct procedures at every stage determines how the house will perform in the decades ahead.

Throughout his career, Tomáš has worked on dozens of sites of different sizes and types. He understands timber construction, material tolerances and how to find practical solutions when site conditions demand them, without compromising quality. He is an experienced professional who knows what he is doing and why. Every completed house benefits from his more than 30 years of experience and personal responsibility for the work.

Welcome Vítali Matrya is the youngest member of the GRIZZONI production team and at the same time proof that talent and working morality are not a matter of age. He worked in production for one year and during that time he was prepared for a reliable and accurate worker to whom the team trusts in key operations.

Vítali operates the saw and cuts the components used to assemble the panels. Precise cutting is the foundation of the production process: each timber must have the right dimensions, the correct angle and a clean cut. He understands this responsibility and approaches his work with discipline and attention to detail.

Working with experienced colleagues, Vítali keeps learning and improving. His approach is simple: do the job properly, ask when unsure and never neglect the details. People like him are the backbone of production. With his career ahead of him, GRIZZONI gives him an environment in which to develop his skills and become an experienced specialist.

With almost twenty years of experience in construction and woodworking, he brings independence, reliability and practical expertise to the team. He understands how each task fits into the wider project and turns that understanding into high-quality work.

In the workshop, Vlado assembles panels and prepares components. He is skilled with hand and power tools, understands material properties and organises his work efficiently, even under tight deadlines. For each component, he focuses on clean workmanship, accuracy and the details that determine the finished panel’s quality.

Vlado is a calm, focused worker whose results speak for his approach. Colleagues value his reliability and consistency. His daily work helps maintain the quality of GRIZZONI production.
