Serial is fast

Serial is fast

"The efficiency is unbeatably good. The collaboration with Tece went excellently from the start and was closely coordinated. I am thrilled with the product." Burak Baser from the German housing association Ingelheim am Rhein (WBI) is full of praise for the prefabricated installation walls from Tecesystem. They were used in a WBI construction project in the Frei-Weinheim district in the immediate vicinity of the Rhine, which was completed a few months ago.

It is a very special project because it combines new construction and existing buildings. In total there were 72 residential units. Of these, 29 apartments were renovated to make them more energy efficient. In the sanitary rooms, WBI opted for industrially prefabricated installation walls from Tecesystem. They were used in five three-story residential buildings. When renovating the lines, new supply lines could be installed efficiently and in accordance with standards.

Prefabricated assemblies offer real advantages: They ensure continuous construction progress right from the start, minimize coordination effort and simplify work on the construction site. Plumbers and drywallers do not have to assemble installation walls and shafts from many individual parts in narrow bathrooms. Instead, the installation walls are modular and arrive at the construction site at the right time, completely prefabricated from the factory.

Time-consuming assembly steps are no longer necessary. Saving time on the construction site and reducing errors are crucial factors in interior design. In the end, everyone benefits from this: the building owner, because he can rent out the property more quickly. The planner because the planning, tendering and execution process is optimized. The craftsman who carries out the work can transfer the warranty for the prefabricated installation wall with all installations to the system manufacturer and work much more efficiently on the construction site during assembly.

"The planner clearly introduced the topic of Tecesystem into the project early on. Contact with Tece arose in phase three. We already had experience with serial renovation, but not with the use of industrially prefabricated installation walls," explains WBI man Baser. Due to the large number of identical floor plans in the sanitary rooms, planner Tomé Rodrigues, owner of the RPB Rodrigues planning office TGA, recommended using this technology.

Modular construction also optimizes the work for the planner - for example the creation of the bill of quantities: "Many small components, from wall panels to apartment water meters to the fire protection sleeves, are no longer advertised individually, but are part of a finished item, namely the manufacturer's individual register, which is created together in the planning phase," explains Rodrigues. “The position worked out as part of the planning then ensures execution without any additions.”

Rodrigues and his team submitted the implementation planning with pipe network calculations to Tece. Tece uses this to create the production drawings of the individual installation walls with the corresponding pipe dimensions. Before the final design, application engineers check the relevant dimensions and details on site and inspect the delivery and unloading conditions. A final check and approval of the production drawings takes place in close cooperation with the executing company and the planning office. This means that any errors are identified in good time before production.

The Tecesystem installation walls offer security because they arrive directly at the construction site just-in-time from the factory. They are completely piped, tested and only need to be aligned and screwed together. In Ingelheim, shafts with half-height walls were used. Only two fitters from the specialist craftsman Weikinger carried the walls to their destination in the respective buildings. They aligned them and assembled them. The pipes in the shafts were then connected to each other on each level. After a successful pressure test, you can begin cladding with plasterboard.

“With conventional construction we would have had to at least double the manpower,” estimates WBI representative Baser. "This is a significant advantage in the renovation: If everything is as well planned as with Tece, then we will be finished in two or three days. What would otherwise take two or three weeks," adds planner Rodrigues.

In times of a shortage of skilled workers, the use of skilled personnel is reduced, there is less risk potential in terms of defects and construction delays and therefore far fewer errors than in conventional construction methods. WBI man Baser was quickly convinced: "You could immediately see from the first delivery how quickly it was done. The first installation walls arrived at the topping-out ceremony and two days later the raw installation was already finished. Such an efficient implementation is remarkable," he says. Postscript: “That speaks for the serial renovation at this point.”

He can well imagine further collaboration: "There is nothing wrong with using prefabricated assemblies again in the future. Serial renovation is not only an excellent solution for old buildings - I also see great potential in new buildings," he says. “The housing market is so tense, we would be happy if we could achieve our goal more quickly with a system like this and create living space.”
