The cities of tomorrow are smart. They are built on citizen-friendly services and well-maintained infrastructure, enabled by smart technologies, mass data and a vast ecosystem of diverse service providers. Stara now invites you to take part in building the future of city maintenance through operational and service innovation, utilizing IoT and mass data.

As part of the EU funded 6Aika initiative, the Cities of Helsinki and Tampere and the University of Tampere’s Research and Education Centre Synergos, have launched the Urban Big Data Project, ”Urban big data as innovation platform in smart city context”, also known as Reboot the City. With this Project Helsinki and Tampere will develop their capability to create exploitable big data to be utilized as an innovation ecosystem and platform for agile digital enterprises in Helsinki and Tampere.

Helsinki City Construction Services, Stara, is an expert in the fields of construction, environmental management and logistics. With almost 1500 employees and hundreds of utility vehicles and other machines it is responsible for maintaining the streets, parks and some buildings in the city. They have a crucial role in making sure life runs smoothly in an enjoyable capital city – whether it shines, rains or snows.

As part of Reboot the City, Stara is now hosting an innovation challenge to improve city maintenance’s operational efficiency through IoT and mass data. The ultimate goal is to enable demand-driven production to better serve the customer – the city and its citizens.

The Challenge

Stara’s hundreds and hundreds of utility vehicles and maintenance machines (incl. e.g. smart garbage cans and robot lawnmowers) create massive amounts of data, which has a lot of potential to help optimize their locations, routes, and usage. IoT platforms and solutions could completely change the way city maintenance is planned and managed, but such tools are not used at Stara yet. They are eager to learn more about these tools and see them in action with city maintenance.

Utilizing city maintenance and utility vehicle data could also help create new kinds of services for the city, and help evolve maintenance work by replacing or improving old ways of working. This could be done by applying modern technologies and devices, and by creating new service concepts, that deliver better results more efficiently than the old ones. Stara is always open for better ways to deliver service to the city, whether it is through its own production or subcontractors.

Therefore, we are looking for data scientists, IoT experts, software developers, service designers as well as startups to help create and apply new solutions, methods and services that either improve Stara’s operational excellence, or enable demand-driven service.


To help the development of proof-of-concepts during the challenge, we have reserved some key people and resources to support your work.

Mentors, experts and customers

Each team will be assigned with their own mentor from Stara. There will also be other industry experts and data/system specialists from Stara to help teams with their work.

Available data

Stara has a multitude of operational data sources that can be utilized by teams during the challenge. Available sources include information and data about the utility vehicles/machines and their locations, as well as about the streets, parks and their maintenance. The most relevant open data sources include the following:

  • Weather data from (data dumps:
  • National Road Weather Seminar presentations
  • Helsinki City map service
  • Helsinki city 3D map
  • Living Lab Bus project
  • Register of public areas in Helsinki
  • Finnish Meteorological Institute’s open data
  • Helsinki Loves Developers’ open data sets and APIs, e.g. for snowplows
  • Finnish Transport Agency’s open data on roads and traffic
  • GeoServer API
  • Street maintenance costs (report only in Finnish)
  • Street maintenance classifications (report only in Finnish)

Data sources will be presented in more detail and additional sources can made available for participating teams as needed. Teams are also free to use any other open data sources they feel relevant.

Additional tools and tech

Among other ideas and solutions, Stara is eager to see IoT platforms in use. Teams are offered a chance to use Elisa IoT platform, as well as IBM Bluemix and Watson platforms if they choose. Access to other IoT platforms can possibly be made available by team’s request. Samsung consumer electronics such as VR gear, smartphones and tablets are also available for use during the challenge.


The teams compete for pilot projects worth 20 000 euros. Each participating team will be paid a reward of 800 eur. Rewards are paid against invoice after the team has presented their demo and the customer has made the decision about the pilot (this will happen within 30 days).


Applications close – September 8th

Applicants informed about the selections – September 15th

Challenge kickoff and visit to Stara site (mandatory 1+ person representation from each team) – September 22nd 10-12am (Kyläsaari, Helsinki)

Hackathon (mandatory for all team members) – October 6th 10 am – October 7th 6 pm at Elisa HQ (Pasila, Helsinki)

Pilot proposal submission DL (from best teams chosen by jury) – October 20th

Pilot phase – November –January


Apply with a team of 2-3 people. All applications will be reviewed after the deadline and all applicants will be informed one week after the deadline. Groups that submit early have a small advantage because we have more time to read their applications. 6-8 teams will be selected to join the challenge.

Who will own my idea?

Ideas are free for everyone to use but the IPR for any software codebase or documents produced during the competition will stay with the team. The host has the first right of refusal to negotiate further collaboration with the team to purchase or continue working on the project initiated during the challenge.
