EN 🇬🇧 There is no second opportunity to ask questions in the first phase of the competition.

EN 🇬🇧 There is no second opportunity to ask questions in the first phase of the competition.

EN 🇬🇧 Competitors are not required to have any certificates or be members of any organisations. However, as the competition programme states, at least one member of the working group must be qualified to practise landscape architecture in their country. In the second phase of the competition, the working group will also be required to include a geotechnical engineer who is qualified to design foundation structures for infrastructure projects in the ‘exceptionally difficult’ category. Any landscape construction in Helsinki must follow the Finnish framework for sustainable landscape construction (KESY). You can familiarise yourself with the KESY framework here For more on these topics, see sections 1.2 and 2.1 of the competition programme.

EN 🇬🇧 All evaluation criteria are equally important.

EN 🇬🇧 It is not mandatory to include a geotechnical expert in the working group during the first phase of the competition, but it is recommended that a geotechnical expert with knowledge of Finnish soil conditions be involved in the team as early as possible. In the second phase of the competition, the working group must include a geotechnical engineer in exceptionally demanding geotechnical infrastructure design (FISE qualifications).

EN 🇬🇧 No separate registration is required for the competition. Eligibility is defined in section 1.2 of the competition programme. In the first phase, at least one member of the working group must be licensed to practise landscape architecture in their country. The competition entry must be drawn up in accordance with section 6.1 of the competition programme and submitted via the competition website by the deadline.

FI 🇫🇮 Kilpailutehtävänä on Hermannin rantapuiston toteutussuunnitteluun tähtäävän suunnitelman laatiminen. Tehtävänä on laatia puistosta yleissuunnitelma mittakaavassa 1:1000 sekä tarkennoksia suunnitelman kannalta oleellisimmista kohdista. EN 🇬🇧 The competition assignment is to draw up a general plan for the implementation of Hermanni Waterfront Park. The task is to draw up a general plan for the park at a scale of 1:1000, as well as details of the most important parts of the plan.

FI 🇫🇮 Kilpailussa on tavoitteena luoda puistosta yleissuunnitelma mittakaavassa 1:1000, jota tarkennetaan ja kehitetään jatkoon päässeiden osalta kilpailun 2. vaiheessa tuomariston jatkosuunnitteluohjeiden mukaisesti. Kilpailun toisessa vaiheessa lähtötiedot tarkentuvat esimerkiksi baanalinjauksen ja koulun pihan suunnittelun suhteen, joka mahdollistaa kilpailutöiden tarkemman yhteensovittamisen niiden kanssa. EN 🇬🇧 The aim of the competition is to create a general plan for the park at a scale of 1:1000, which the shortlisted competitors will refine and develop in the second phase of the competition in accordance with the jury's further planning guidelines. In the second phase of the competition, the initial data will be refined in terms of aspects such as the Baana alignment and the planning of the schoolyard, which will enable the competition entries to be coordinated more precisely with these aspects.

EN 🇬🇧 In the Kalasatama area, which also includes the competition area, a principle has been established whereby all developers in the area contribute to the acquisition of public art. Hermanni Waterfront Park will also feature public art; however, this will be included in the competition only in the second phase.

EN 🇬🇧 No final decision has been made at this stage regarding the total budget for the park. However, in accordance with section 5 of the competition programme, the financial feasibility of the competition entries, i.e. the feasibility of the construction and maintenance costs, is one of the evaluation criteria for the entries.

In the second phase of the competition, we will request materials that will help us make a more accurate cost estimate.

EN 🇬🇧 Micro piling is not recommended because the stability of the area is generally insufficient without ground reinforcement. There is also excess pore water pressure in the area, which makes piling difficult. Furthermore, the bedrock surface is mostly deep in the planning area, which also makes piling expensive.

EN 🇬🇧 Remediation objectives may vary in different parts of the park depending on the intended use of the area.

Yes, partial remediation solutions are acceptable in less sensitive areas.

FI 🇫🇮 Kilpailuohjelman mukaisesti kilpailualueella sijaitsevat toiminnot poistetaan ennen puiston rakentamisen aloittamista. Alueella olevia rakenteita ei ole inventoitu eikä niiden huomioiminen suunnitelmissa ole tarpeen. Maassa saattaa olla purkutoimenpiteiden jäljiltä rakenteita, kuten paaluja, joita ei kuitenkaan tarvitse poistaa. EN 🇬🇧 In accordance with the competition programme, the functions located in the competition area will be removed before the construction of the park begins. The structures in the area have not been inventoried, and it is not necessary to take them into account in the plans. There may be structures, such as piles, left behind after the demolition work, but these do not need to be removed.

FI 🇫🇮 Pilaantuneen maan puhdistamisesta ei ole vielä suunnitelmaa. Kunnostustavoitteet määritetään riskinarvion avulla. Todennäköisesti syvemmällä olevat haitta-ainepitoiset massat voidaan jättää paikoilleen, jos niitä ei rakentamisen vuoksi tarvitse kaivaa. EN 🇬🇧 There are no plans yet for cleaning the contaminated soil. The remediation targets will be determined through a risk assessment. It is likely that deeper layers containing harmful substances can be left in place if they do not need to be excavated for construction purposes.

FI 🇫🇮 Kunnostustavoitteet määritetään riskinarvioinnin avulla ja hyväksytetään ympäristöviranomaisella. Oletettavasti ainakin osa maa-aineksesta joudutaan poistamaan tai eristämään esim. peittämällä. Kilpailuun ei sisälly kunnostustavoitteiden määrittäminen eikä pilaantuneen maaperän puhdistamisen suunnittelu. EN 🇬🇧 The remediation targets will be determined through a risk assessment and submitted to the environmental authority for approval. Presumably, at least some of the soil will have to be removed or isolated by covering it, for example. The competition does not include setting remediation targets or planning the cleanup of contaminated soil.

EN 🇬🇧 The area cannot include a bathing area where swimming takes place in natural waters. The contamination does not otherwise prevent access to the sea. In addition to the contamination, shore construction must take geotechnical limitations into account.

EN 🇬🇧 Any soil fillings must not contain materials that could alter soil conditions (e.g. pH) in a way that increases the migration of harmful substances. When using expanded polystyrene, the effect of buoyancy must be taken into account, especially if the material is intended to be used as a lightening material.

EN 🇬🇧 Invasive alien species (IAS) listed on European Union’s the List of species of Union or national concern (latest update 15.8.2023 (912/2023)) may not be cultivated, sold or marketed in Finland. Releasing these species into the environment is prohibited, and any existing populations must be removed. According to Alien species strategy of Helsinki (2022), harmful alien species should be eradicated during construction projects. However current legislation does not mandate their control. National guidelines for prevention and management of invasive can be found at vieraslajit The City of Helsinki maintains a list of species currently regarded as invasive and harmful, detailed in Haitalliset vieraskasvit, joita ei istuteta - Helsingin kaupunkikasviopas For the implementation phase, the city provides guidance cards that give instructions on the eradication of invasive species.

The aim is to reduce the number of harmful invasive species through control and maintenance, using methods such as excavation, cutting, or covering, which help weaken the species and their populations.

The design solutions planned for the competitions site will determine which control methods are most appropriate. Control efforts may need to continue over extended periods to fully remove invasive populations. Soil and plant waste generated during eradication must be disposed of in accordance with current regulations. Links:

EN 🇬🇧 Most of the bird species in the area are migratory. The open parts of the site provide suitable habitat for grazing goose species such as barnacle goose (Branta leucopsis) and Canada goose (Branta canadensis), both of which are abundant in Helsinki Dense shoreline vegetation supports a variety of insectivorous bird species. On a typical spring day, around 100 bird species can be observed on site, the majority being migratory. In winter, approximately 10–15 species are likely to be present.

EN 🇬🇧 A bat survey was conducted in the area in 2024. Report of this survey (in Finnish) is included as competition programmes as appendix no 10. On the page 10 of this report, you can find key findings regarding locations of the observations of the two most common species (Eptesicus nilssonii & Myotis daubentonii). The most suitable habitat for bats is marked with purple.

EN 🇬🇧 In the Vegetation survey (2025), the area’s habitats have been divided into three main categories: shoreline habitats, meadow-like areas, and wooded areas. This categorization illustrates the presence of distinct and interesting biotopes within the area and serves as background information for the competition. However, the boundaries are partly interpretative and the entire competition area has not been marked with precise boundaries. This should be taken into account when using the information. The competitors may adjust and define the boundaries, for example, by using aerial images. The vegetation survey will be included in the competition’s background materials for participants’ use.

EN 🇬🇧 The vegetation survey does not include a detailed classification of plant species based on flowering periods, colors, or similar characteristics. The attached vegetation report examines vegetation primarily from the perspective of biodiversity. The observed species are listed in the report.

EN 🇬🇧 There is no completely barren ground without regular disturbance such as trampling or flooding in the area.

EN 🇬🇧 The presence of bats is most likely more associated with small water bodies rather than with vegetation in the area.

EN 🇬🇧 The only Annex IV species that have been surveyed in the area are bats. There is a report (in Finnish) about the species (3) and their abundance in the area.

EN 🇬🇧 Plant inventory on the competition area was conducted in 2025. The aim was not to survey all plant species, but rather to gain a clear understanding of the level of biodiversity. No critically rare, endangered or vulnerable plant species were observed during inventory.

EN 🇬🇧 According to the survey (Appendix 10), the peak activity period is July, but some activity is observed throughout the summer (May–September).

EN 🇬🇧 There is no detailed tree survey that shows location, species or health status of individual trees. Wooded areas have been invented as biotopes in plant inventory conducted in 2024. The survey is available on the competition website under the downloadable materials section as Appendix 9. Vegetation survey.

EN 🇬🇧 You may contact Finnish Association of Nursery production (Taimistoviljelijät -Plantskoleodlarna ry) for more information regarding plants and vegetation.

EN 🇬🇧 According to the survey (Appendix 10), the peak activity period is July, but some activity is observed throughout the summer (May–September). Bat activity is highly related to weather conditions.

EN 🇬🇧 Fish monitoring using gillnets is conducted biennially in Vanhankaupunginselkä Bay. The fish community in the area is characteristic of sheltered, eutrophic bays of the Baltic Sea, with a relatively high biomass of cyprinid species. In addition, Vanhankaupunginselkä Bay has been identified as an important spawning ground for predatory species such as European perch, zander, and northern pike. These spawning sites are primarily located outside the competition area, along the northern and eastern shores of the bay. However, a pond within the competition area that connects to Vanhankaupunginselkä Bay serves as a smaller-scale spawning habitat for cyprinids and sticklebacks. The bay also functions as a vital waterway for anadromous species that spawn in the Vantaanjoki River, including sea trout, Coregonus lavaretus, and European smelt.

EN 🇬🇧 The Vegetation survey (2025) lists the invasive plant species observed within each biotope. The inventory does not include underwater habitats. Competitors may also access observations of invasive alien species as geographic data through Helsinki Map Service

EN 🇬🇧 The water quality in Vanhankaupunginselkä Bay is deteriorated, with both ecological and chemical status classified as poor. As a river estuary, the bay is heavily influenced by the water quality of the Vantaanjoki River. The river’s extensive catchment area contributes to high loads of turbid water, nutrients, and harmful substances. The pH of the water typically ranges between 7 and 9, depending on the season. Studies have found significant concentrations of harmful substances in fish from the bay, and available data indicates contamination in both the water and sediment. Water quality is monitored year-round by the Environmental Services of the City of Helsinki. All data is stored in the VESLA system (Information System for the Status of Surface Waters), which is available only in Finnish.

EN 🇬🇧 Water quality in the Hermanninranta area, which is part of Vanhankaupunginselkä Bay, is monitored year-round by the Environmental Services of the City of Helsinki. All data is stored in the VESLA system (Information System for the Status of Surface Waters), available only in Finnish. The ecological and chemical status of the water in Vanhankaupunginselkä is poor. The bay is strongly affected by the Vantaanjoki River, whose large catchment area results in high nutrient and contaminant loads. Annually, the river contributes approximately 1,268 tons of nitrogen and 69 tons of phosphorus to the bay. Despite the contamination, the water is generally well oxygenated, with an average oxygen saturation of 96%. Seasonal variations affect water quality parameters. Harmful substances have also been detected in fish from the area, and both water and sediment show signs of contamination.

EN 🇬🇧 No hydrological data is available for the competition area.

EN 🇬🇧 Qualitative treatment of stormwater before discharging it into the sea is recommended. However, when planning treatment solutions, it is important to take into account the contaminated soil in the area. Any additional absorption of stormwater and the discharge of water into the contaminated soil must be avoided. The stormwater channel to be built in the area will be isolated from the contaminated soil by means of special isolation solutions.

EN 🇬🇧 The exact dimensions of the stormwater channel are not available, but its approximate size can be estimated from the base map. No stormwater modelling has been carried out for the area, and therefore no flow data is available for the stormwater channel.

FI 🇫🇮 Alueella on paksut savi- tai liejukerrokset, joiden päällä on sekalaista täytemaata. Savi- ja liejukerroksiin vesi ei imeydy ja täytemaakerroksissa veden suotautumisnopeutta on vaikea arvioida, koska materiaali on hyvin sekalaista. Pohjatutkimuksia alueella on tehty, mutta niiden perusteella ei voida arvioida veden suotautumisnopeutta. EN 🇬🇧 The area has thick layers of clay or mud, covered with mixed fill soil. The clay and mud layers do not absorb water, and it is difficult to estimate the rate of water infiltration in the fill layers because the material is very mixed. Soil surveys have been conducted in the area, but they do not provide a basis for assessing the rate of water infiltration.

FI 🇫🇮 Hermannin rantatielle on toteutettu hulevesien biosuodatuspainanteita suodattamaan ja puhdistamaan kadulta tulevia hulevesiä. EN 🇬🇧 Biofiltration swales have been implemented along Hermannin rantatie to filter and purify stormwater from the street.

EN 🇬🇧 Stormwater collected from the surrounding new residential areas will be directed to the new stormwater channel, which will be isolated from the contaminated soil. The new stormwater channel must delay and purify stormwater before discharging it into the sea. There is no need to specifically prevent the natural absorption of floodwater or rainwater that falls locally in the area.

EN 🇬🇧 Hermanninterassi (Hermanni Terrace) will be built above the flood level, and the area between it and the waterfront park will be designed as a sloping solution. The competition area borders the lower edge of the Hermanninterassi slope. This means that the planning of the Hermanninterassi is not part of the competition, but submission entries must be compatible with the plans for the Terrace.

EN 🇬🇧 The competition area borders the lower edge of the Hermanninterassi (Hermanni Terrace) slope. This means that the planning of the Hermanninterassi is not part of the competition, but submission entries must be compatible with the plans for the Terrace.

EN 🇬🇧 The competitors must follow the delineation of the Hermanninterassi (Hermanni Terrace) reference plan in the park plan bordering the northern section of Hermanninterassi for which no detailed plans have yet been drawn up. However, when it comes to the sloping transition area, competitors have more freedom to develop ideas and propose design solutions. The reference plan for Hermanninterassi is presented in Appendices 2 and 7.

FI 🇫🇮 Hermanninterassin korot vaihtelevat +3,2 ja +4,7 m välillä. Suunnitelmat tulee sopeuttaa kilpailuohjelman kuvassa 13 annettuihin korkotasoihin ja liitteessä 6 annettuihin Hermanninterassin rinteen korkotasoihin. EN 🇬🇧 The elevation of the Hermanninterassi ranges between +3,2 and +4,7 m. The plans must be adapted to the elevation levels shown in Figure 13 of the competition program and to the slope elevations of the Hermann terrace provided in Appendix 6.

FI 🇫🇮 VU ja VK alueille ei ole vielä määritelty tarkkoja korkotasoja. Jotta alueet olisivat suojassa useimmin toistuvilta tulvilta, niiden tulee olla ylempänä kuin +2.8 m. EN 🇬🇧 Specific elevation for the VU and VK areas have not yet been determined. To ensure that these areas remain dry during the most frequently occurring floods, they should be designed at an elevation of +2.8 m or higher.

FI 🇫🇮 Kilpailuohjelman mukaisesti rannan pääreitti ja uudemmat pienemmät reitit saavat aika ajoin jäädä tulvan alle. Näiden reittien palvelutason ei siis tarvitse olla sellainen, että ne pysyvät jatkuvasti kuivina, vaan tulvien satunnainen esiintyminen on hyväksyttävää.

Tulvien esiintymisen vaihtelusta on kerrottu tarkemmin kilpailuohjelman kohdassa 4.9 sekä liitteessä 12. Kilpailijoiden odotetaan ratkaisevan tulviin liittyviä haasteita kilpailuehdotuksissaan. EN 🇬🇧 In accordance with the competition programme, the main route and newer, smaller routes are allowed to be flooded from time to time. The service level of these routes does not need to be such that they remain dry at all times; occasional flooding is acceptable.

More detailed information on the variation in flood occurrence is provided in section 4.9 of the competition programme and in Appendix 12. Competitors are expected to address the challenges associated with flooding in their entries.

EN 🇬🇧 It is possible, but will probably require ground reinforcement measures that may be difficult and expensive to implement. The feasibility of embankment filling must be examined in more detail on a case-by-case basis during further planning at the latest. However, occasional flooding of the Baana is acceptable in the waterfront park, so it is not necessary to raise the ground level to +3.3 on its account.

EN 🇬🇧 The competition brief does not set any restrictions on structure heights. However, the area’s challenging soil conditions and their implications for construction must be taken into account. Section 4.6 of the competition brief (‘Geotechnical Conditions’) provides recommendations concerning structures and foundations.

EN 🇬🇧 The aim of the competition is to preserve the park's current natural environment as far as possible and allow it to develop into an increasingly diverse ecosystem. No specific ratio between permeable surfaces (softscape) and impermeable surfaces (hardscape) has been defined.

EN 🇬🇧 The closest canoeing point is located at Kivinokka, on the opposite side of the bay from the competition area. It is not mandatory to place a canoeing or rowing point within the competition area; competitors are free to propose other functions due to the removal of boat storage facilities.

FI 🇫🇮 Alueen veneenlaskupaikan ja rantapuiston suunnittelussa tavoitteena on tukea kevyttä veneilyä, erityisesti soutu- ja melontatoimintaa. Veneiden laskuun voidaan esittää ramppi, joka soveltuu trailerilla tuotaville ja veteen laskettaville veneille. Lisäksi voidaan ehdottaa esimerkiksi muita vesillä liikkumista tukevia rakenteita, kuten venevalkamaa, melontalaituria sekä varusteiden säilytys- ja käyttötiloja rannassa. Mitoitus ja tilavaraukset tulee esittää kilpailuehdotuksessa valitun konseptin mukaisesti. Nykyisen betonirakenteisen nostolaiturin osalta voi ehdottaa muutakin käyttöä, mikäli alueella ei enää säilytetä veneitä talvisin eikä laiturilta näin ollen tehdä jatkossa raskaita nostoja. Ehdotuksissa voidaan esittää rakenteiden muokkaamista palvelemaan kaupunkilaisten muuta virkistyskäyttöä. EN 🇬🇧 The boat launch site and waterfront park should be designed to support light boating, particularly rowing, canoeing and kayaking. For boat launching, there may be a ramp suitable for boats transported on trailers and launched into the water. In addition to this, other structures that support water transport can be proposed, such as a boat harbour, a canoe and kayak pier, and equipment storage and usage facilities on the shore. Dimensions and space allocations must be presented in the competition entry in accordance with the selected concept. Other uses can be proposed for the existing concrete lifting dock if boats are no longer stored in the area during the winter and the dock is therefore no longer used for heavy lifting. Entries may include adapting the structures to serve other recreational purposes for the city's residents.

FI 🇫🇮 Alueelle toivotaan monipuolisia veneilyn, muun vesillä liikkumisen sekä muita merellisen virkistyksen mahdollistavia rakenteita. Ehdotuksissa voidaan vapaasti esittää tämän tavoitteen mukaisesti toimintoja sekä rakenteita asemakaavan määräykset huomioiden. Vesialueelle sijoittuvat satamarakenteet toteutetaan lähtökohtaisesti kelluvina. EN 🇬🇧 The area should be equipped with a variety of structures for boating, other water transport and other forms of marine recreation. Entries may freely present functions and structures in line with this objective, taking into account the provisions of the local detailed plan. Harbour structures located in the water area will, in principle, be constructed as floating structures.

EN 🇬🇧 The Hermanninranta residential area is still under construction, and no resident surveys or similar interactions have been conducted regarding the park so far. The actual interaction regarding the park plans will take place during the second phase of the competition. At the end of the second phase, the competition entries will be published on the Kerrokantasi service, where residents and other users can provide feedback and comments.

EN 🇬🇧 The construction of the Kalasatama area began in 2009, and the area is expected to be completed in the early 2040s. The area currently has a population of around 12,000, which is expected to grow to around 32,000 by the 2040s. Population growth is steady, at around 1,000 residents per year. Hermanninranta, located in the northern part of Helsinki's Kalasatama district and bordering the competition area, will be a residential area with services and a population of approximately 5,500. In addition to Hermanninranta, plans are underway to develop the Kyläsaari area, which will also be a service-oriented residential area for approximately 5,000 new residents. The area has a diverse population structure and all forms of housing production. Housing prices in Kalasatama are approximately 25% higher than the average housing prices in Helsinki. The open statistical databases in the Helsinki Region allow you to view population data for Kalasatama, but these are only available in Finnish. Links to the tables:
