As part of EnStadt: Pfaff, the former boiler house is to be converted into a visitor center, the so-called “real laboratory center”.

The historic boiler house is not a listed building and was built in 1906. Originally it was a rectangular hall with a cellar, around 43.80 m long and 17.36 m wide. The roof construction consisted of a gable roof with a 8.85 m eaves height and 11.86 m ridge height with a skylight. The side walls have pilaster strips and facade-high pairs of windows.

The building was severely damaged in the Second World War. About two-thirds of the hall was rebuilt and the roof was extended in height with a steel and glass construction.

It is planned to renovate the entire sandstone facade of the building. This includes the removal of the roller shutter and the restoration of the former windows on the east facade, the opening of all windows on the west facade and the renovation of the existing windows.

For structural reasons, the existing south facade is no longer sustainable. Therefore, a facade made of reddish fair-faced concrete is planned in a horizontal wooden formwork. The new design of the south facade, based on the north facade, is divided into 3 parts. The dummy joints necessary for structuring are also used as construction joints during the concrete work. At the top, a concrete gable triangle will be added, corresponding to the existing facade in the north, which reinforces and emphasizes the tripartite division of the new south facade. Due to numerous additions and breakthroughs after the Second World War and the resulting weakening of the facades, the southern parts of the east and west facades are also made with reddish exposed concrete. Thus, the newly built concrete facade is pulled around the corner and pragmatically connects to the existing building that is worth preserving. The new openings are also designed as simple rectangles, the width and height of which are based on the existing structure. To protect the main entrance from the weather, a concrete canopy is placed over almost the entire width of the south facade.

In the future, visitors should be able to enter the “Reallabor Zentrum” from the south, as a forecourt is to be created as part of the development of the quarter. Accordingly, an entrance area and windows in the characteristic historical style are required.

As part of the roof renovation, the plan is to dismantle the steel and glass construction on the roof and replace it with a new framework construction with a covering made of standing seam sheets and an integrated, semi-transparent photovoltaic light roof. Insulation of the roof area is planned.

The planned construction work includes the shell work for the redesign and redesign of the former boiler house on the Pfaff site in Kaiserslautern. The building plot is located on the former site of the sewing machine manufacturer Pfaff north of the railway line. Access to the construction site will be made possible via the north, as other work will take place in the area of the main southern access to the area in parallel with the execution time. The construction site must be fenced in and equipped with an access gate in accordance with the construction site facility plan. Parking and storage areas for containers can also be found in the construction site facility plan. When entering and exiting construction sites, the traffic law requirements and local conditions must be observed. Transport routes on the public traffic area must be kept free at all times and cleaned with a sweeper if necessary (in the event of contamination by the contractor). Costs are borne by the contractor. The crane location is shown in the construction site equipment plan. Changes to the crane location must be known in good time and coordinated with site management and the client. It should be noted that there are several residential buildings with 2 storeys in the swivel area of the crane. The load from the crane must be statically verified.

The aim of the structural measure is to redesign and redesign the former boiler house to become the “Reallabor Zentrum” visitor center. These include demolition work, securing the existing structure, scaffolding work, masonry work, concrete work in exposed concrete quality as well as the production of a new roof structure as a half-timbered construction with an insulated standing seam roof covering.
