The right schedule for renovation / new build

Refurbish roof with new covering, thermal insulation, and reinforcement of the load-bearing system.

Seal basement, insulate basement walls and ceilings.

Refurbish exterior walls with high-value thermal insulation, update windows and doors with thermal glazing, potential installation of a photovoltaic system.

This is to be installed in a way that is tailored to the newly-insulated exterior shell.

The interior work represents the last phase of the refurbishments and forms the completion of the renovation works.

The pre-project forms the most important phase of the entire building process. The basis is the specification sheet, where the most important points are regulated: Reference date, energy standard, materials, design, approximate living area, number of rooms and their size, ancillary rooms, building technology, options for future alterations.

The planning application is prepared by the architect and is based on the pre-project that has been completed and accepted by the owner. Apart from the pre-construction drawings, this also includes the profiling of the planned building project.

The implementation planning and detailed planning defines what effectively is to be completed and starts after the building permit. This results in a detailed cost estimate and a detailed schedule. When these documents have been approved, the individual works are tendered and offers are obtained from various companies. Based on the award to the appropriate contractor, the latter is contracted.

The implementation works can begin when the building permit is available. Demolition and clearing works, excavation pit and excavation support.

Shell construction 1 includes essentially the support structure of the building as well as the basic installation of the building technology (e.g. pipes and cables inserted in the concrete).
The follow shell construction 2 relates to the building shell (roof, facade (e.g. insulation and rendering), windows, and exterior doors and gates). The building is now weather-tight and the interior construction can begin.

The handover of the object to the owner is the big event when all works have been completed. An important part of this is the building inspection and the recording of any defects and finishing work. With the building inspection, the proper guarantee works begin. (2 years for apparent defects and 5 years for hidden defects). At the handover of the object, the owner is given the revision documents (list of contractors, plans, manuals, etc.). The final account is usually provided 1-3 months after the handover of the object.
