Prefabrication | MODULBAU

"Particularly in solid wood construction, prefabrication in the factory is a guarantor of high high efficiency and quality. In addition, the work in the independent of wind and rain on the construction site. This ensures a fast completion of the timber construction."
Alexander Leidorf
Founder and Managing Director of Leidorf GmbH

Modular construction | Tinyhouse

The finished modules are assembled in the factory and then put together on site.

Lifting systems

We create boreholes for the common lifting systems, e.g. from the Pitzl company.

Holes / Component

Boreholes - Colour coating - impregnation - Removal of residual radii - Attachment of metal parts - Component pre-assembly

Fire protection cladding

We install gypsum plasterboard or gypsum fibreboard already in the factory - this saves assembly time on the construction site and also scaffolding, for example.

At the construction site, the modules are placed on the foundations and the building services are connected. Done!

Cross Laminated Timber (CLT) prefabrication has revolutionised the construction industry and opens up a multitude of possibilities for efficient, precise and sustainable building. This innovative method has proven to be groundbreaking and is increasingly used in a wide range of construction projects worldwide.

CLT prefabrication is at the heart of this groundbreaking development. It involves the production of CLT elements such as wall, ceiling and floor elements as well as prefabricated modules in a controlled production environment before they are transported to the construction site and installed there. This method offers a wealth of benefits that surpass traditional construction methods.

A central aspect of CLT prefabrication is precision, which is achieved through state-of-the-art technology and computer-controlled machines. Each CLT element is manufactured with millimetre precision, resulting in high dimensional accuracy and minimal waste. This significantly reduces the risk of errors and enables smooth assembly on site.

Prefabrication also enables efficient mass production of building elements. By planning CLT elements in advance and producing them in large quantities, the construction time is significantly reduced. This leads to significant cost savings and enables faster completion of construction projects.

On-site assembly is also much easier and faster. The prefabricated CLT elements are already provided with the necessary openings for windows, doors and installations, which significantly reduces working time. This not only minimises disruptions on the construction site, but also helps to improve work safety.

Another key benefit of CLT prefabrication is the improvement in the quality and consistency of the building elements. Precise manufacturing in a controlled environment reduces the risk of construction defects and ensures consistent high quality throughout the construction project. This results in long-lasting buildings with low maintenance requirements and low maintenance costs.

The prefabrication of CLT also has significant environmental impacts. As production takes place in closed workshops, resource consumption, including energy and water, can be managed more efficiently. The use of sustainably managed wood as the main raw material for CLT also supports environmental protection and contributes to reducing the ecological footprint.

A remarkable feature of CLT prefabrication is its versatility. It can be used in a wide range of construction projects, from residential and commercial buildings to public facilities and educational institutions. The flexibility of this method opens up new design possibilities for architects and engineers and enables sophisticated, innovative designs.

In summary, cross laminated timber prefabrication is a transformative force in the construction industry. By combining precision, efficiency and sustainability, this method offers an answer to the challenges of the modern construction world. CLT prefabrication opens the door to faster construction projects, higher quality and greener building. With its numerous advantages, it sets new standards for the future of construction and impressively demonstrates how innovative technologies can permanently change the way we build.
