Pipeline renovation in an old block of flats
The As Oy Helenenkatu 7–9 pipeline renovation was quite a typical pipeline renovation project, and no surprises were encountered. This site, built in 1968, features 35 flats and eight garages.
The property is located behind the Hyvinkää bus station in the old city centre. The five-storey block of flats has two separate stairways. The pipeline renovation was a basic contract that included bathroom renovations, coating of old drain pipes, replacement of switchboards and updating the drawings with regard to water supply and electrical systems.
The electrical systems of the bathrooms were replaced, and a new electric supply was added for the kitchen stoves. Provisions for dishwashers were also made. Chutes for water pipes were built in the stairways, with the water pipes routed to the flats via the bathroom or vestibule. If the chutes were made directly in the bathrooms, this would typically increase the costs and prolong the renovation. In fact, the flats and basement facilities were completed two months before the agreed delivery date.
