Wohnbau Gießen GmbH - Installation work
About This Opportunity
TranslatedThis tender concerns remaining installation works for the completion of the renovation of 52 terraced houses in the Rotklinkersiedlung, Lot 30a, specifically focusing on heating, sanitary, and ventilation technology (5th construction phase). While some works from the original main contract have already been executed, this tender outlines the remaining tasks. The scope of work is divided into three main sections: Heating Technology, Sanitary Technology, and Ventilation Technology.
In the Heating Technology section, previously completed tasks include dismantling, core drilling, installation of district heating substations, and the majority of pipe installations for basement distribution, riser pipes, and radiator connections up to the first floor (gable side). Leak tests have also been performed and documented. Remaining heating works involve connecting the remaining radiator lines on the first floor (gable side), installing all radiators and accessories, filling and venting the system, commissioning the entire installation including setting the district heating substations, and insulating the basement distribution pipes.
For Sanitary Technology, completed works include dismantling, core drilling, pipe installation, leak testing, and the mounting of 12 shower trays. The outstanding sanitary works require establishing the main drainage connection in the basement of each entrance and connecting it to the building's internal plumbing. Additionally, a main water connection needs to be installed and linked to the distribution pipe for each building block. Insulation of basement distribution pipes, installation of all sanitary objects and accessories, mounting of 9 additional shower trays, and the installation of a shaft pump with a pressure line are also required, all to be completed in all five buildings once the external facilities are finished.
This is a works contract in the construction and civil works and energy and power sectors, with a focus on Buildings and HVAC systems. Located in Germany, Europe, this opportunity is open to firms and consortiums.
