This is not a contract notice or invitation to tender, but a request for information regarding the snow management project. OBJECT OF THE PROCUREMENT As Helsinki's urban land use density increases, there is less space available for snow within the urban structure. This results in an increase in the amount of snow that needs to be transported away. There is not enough space to store snow on the streets, snow dump areas are being repurposed, and there are usage restrictions on existing snow dump areas. Snow removal often occurs at nighttime to minimize traffic disruptions and ensure smooth operations. To reduce noise pollution, the opening hours of snow dump areas are restricted, leading to longer transport distances to dump areas that remain open longer. The number of snow dump areas has decreased, and transportation distances have increased, resulting in higher emissions and noise pollution. When the sea-based snow dump area is being abandoned, alternative solutions and policies must be developed to ensure the functionality of the city during exceptional snow conditions. Snow management is further challenged by the unpredictability of winter snowfall and the increase in extreme weather conditions due to climate change. The annual snowfall amounts vary. Based on long-term monitoring, three types of winters have been defined for snowfall amounts: 1. A normal winter in which approximately 50,000 loads of snow (about 875,000 m3) are received at Helsinki's snow dump areas. These winters occur on average every two years. 2. A winter with more snow than average is considered to be a winter in which approximately 125,000 loads of snow, or approximately 2,187,500 m3 of snow, are received at Helsinki's snow dump areas. Such winters are repeated on average about every five years. 3. A winter with a lot of snow is considered to be a winter in which approximately 265,000 loads of snow, i.e. approximately 4,637,500 m3 of snow, are received at the snow dump areas in Helsinki. On average, such winters are repeated about every ten years. Currently, snow is transported from the streets to nine snow dump areas after snowfall, including six land-based dump areas, two melting stations, and one sea-based dump area. These snow dump areas can theoretically receive approximately 200,000 loads of snow. Snow is transported an average of four kilometers one way to a snow dump area. The longest transport distances exceed ten kilometers due to nighttime opening hour restrictions at the snow dump areas. Snow dump areas have been reduced due to increasing urban land use density and will continue to decrease as pressure for other land use increases. Over the past 40 years, there have been seventeen different snow dump areas throughout the city. In 1998, there were thirteen snow dump areas, and by 2023, there are nine snow dump areas. By 2033, there will be only five snow dump areas, and later, one more is expected to close due to urban land use densification. The snow dump areas expected to close by 2033 include the Kyläsaari melting station, the Oulunkylä land-based snow dump area, the Malmi land-based snow dump area, and the Hernesaari sea-based snow dump area. In addition, the Viikki snow dump area is expected to close by 2040. A significant reduction in snow management capacity would mean that Helsinki would be unable to manage snow, leading to operational paralysis as roads and property areas would be filled with snow. The project portfolio for the years 2023–2033 consists of the following five sub-projects (components): 1. Increasing land-based snow dump areas 2. Implementing snow melting stations 3. Enabling local snow storage 4. Establishing principles for sea-based snow dump area 5. Developing innovative snow management solutions The planned procurement concerns the above-mentioned sub-projects. Based on the first phase of market consultation, the procurement authority will consider the appropriate procedure for tendering or the appropriate composition of the procurement components (see the sub-projects above). The second phase of market consultation aims to gain a more detailed understanding of how to define the procurement object in the tender, and what contract terms or pricing mechanisms would be justified to use. Procurement is planned to be carried out in early 2025, with the first contracts being in force in 2025 and valid until 2033. The plan is tentative and subject to change.
