Smart Planning

Develop a technological tool which will improve the planning of new real estate by taking public needs into account automatically and accurately


Planning is the basis for every new real estate project and a fundamental element in urban renewal. It has long term implications not only on the project itself, but also on the community, local urban development and the local or even national economy.

Most property development plans include areas allocated for public institutions and public use such as schools, parks or community centers, and a detailed layout of their size and number. 

Optimal planning of new public areas must take into account various important considerations such as expected demographic growth, existing public uses, current and future community needs, cities’ plans and policies, and social and environmental aspects.
Today, there is no technologically innovative solution for this need. Rather, it is a labor intensive, expensive and long, process. Relevant information needs to be found in various databases, collected, analyzed, and then a public area usage plan must be devised out of this data.  

Smart planning of public uses by developers, planners and entrepreneurs will facilitate the dialogue between the developer, the planner and the municipalities, will ease the process, save time and money and will lead to win-win planning.

Challenge Description

The ultimate goal is to develop an innovative, inclusive, user-friendly platform for planning an optimal program for public uses in new real estate projects. 


Such a platform must take into account all relevant maps, data, policies and guidelines. It should be at least as accurate and efficient as existing solutions, but less expensive and time-consuming. It should be useful and accessible for municipalities, developers and planners.


The desired solution should address the 3 aspects of the existing need:

  1. Find - locate all relevant information, including, for example, residents’ complaints to the city, community groups, building plans submitted by developers, city and regional zoning maps, zoning laws, data from the Central Bureau of Statistics, environmental regulations and infrastructure safety regulations, which are now scattered among many government authorities and websites in various formats (PDF, Word, JPEG).

  2. Process - create an automatic function, i.e a kind of robot, that knows how to extract this information from the locations where it now exists and turn it into easily accessible data in a uniform format.

  3. Generate- develop the platform’s ability to produce a smart program for the optimal use and extent of public spaces in a proposed real estate project, based on established rules and policies, based on the located information.

Outcome: What do we expect at the end of the hackathon?

An advanced technical proposal for at least one of the 3 aspects of the challenge.

Smart Concrete

Design the new generation of concrete sensors.


With more than 7 billion cubic meters each year, concrete is by far the most used material in the world. Although the recipe is simple (cement+aggregates+water+admixtures), complex coupled chemical reactions occur at an early age during the cement hydration process.

Monitoring of concrete is of major importance for the evolution of the material’s properties such as temperature, strength and water content, and to guarantee its integrity during its service life. Thanks to a new generation of sensors that incorporate wireless and long range data transmission, and cloud storage of data, monitoring has become easier and cheaper.

For concrete suppliers, these new sensors can help monitor in real time the evolution of the material's properties. For example, temperature monitoring allows the gaging of the concrete’s strength development. Other properties of interest are relative humidity, pH, and resistivity.

What exists today?

Various concrete sensors are already available on the market. They are based on different types of wireless communication: Bluetooth, Wifi, SigFox, LoraWan (to our knowledge, no RFID active sensor is available on the market). But there are still several unresolved issues:

  • Cost -  Many sensors need to be placed into the concrete, so sensor price has to be much lower than the price of a cubic meter of concrete. A good target to consider is less than 10$ per sensor.

  • Wireless data transmission into concrete - At an early age, concrete is a saturated material, and the weakening of the signal is a problem, depending on the transmission frequency.

  • Robustness - Life on a Jobsite is tough so sensors have to be robust enough and not break during the concrete pouring.

For example, a temperature sensor that can be placed into concrete, with a price lower than 10$ can really change be a game changer (existing solutions cost more than 80$).

Challenge Statement

Develop an embedded sensor for concrete that would allow the monitoring of one or several of the above mentioned properties, or others that are important to the industry.

The main technical issues that need to be resolved are:

  • Data transmission through a metallic environment (rebars, metallic formworks)

  • waterproofing and robustness

  • battery life

  • withstanding temperatures of up to 80°C.

  • keeping cost low 

Outcome: What do we expect at the end of the hackathon?

Of course, we don’t expect a working sensor at the end of the hackathon. We expect at least a set of technical proposals describing the sensor and the corresponding cost:

  • What type of packaging?

  • What type of wireless transmission?

  • What type of battery?

  • What is monitored?

Smart Selling

Develop a platform that would drive people to purchase real estate online


Shopping practices have changed dramatically in the last few years, with more and more people opening up to buying diverse products online, from produce, to furniture, to shoes. The digital domain has changed the world's consumption habits. 

However, in real estate no technological solution has been introduced that would drive people buy property online in large numbers, despite the fact that it is the fastest growing investment track in the world. People might look at real estate online, but they do not make the purchase there.

This is partly due to various legal and bureaucratic requirements, but also due do a psychological barrier potential clients have on this matter. It is an abnormality especially for so-called millennials, most of whom have no problem buying almost anything online.

Sales agents are still the main deal instrument, as it was many years ago. Our challenge is to change that.

Challenge Description

Creating a reliable and easy to use web platform or app that would drive people to purchase real estate online.


This would reduce the need for sales people, and thus reduce costs and allow for more sales to take place, without the need for an agent.

There are various technologies already in place such as VR tours, bots that know the right questions to ask, smart maps and more. However, the challenge is to break the psychological barrier that keeps people from actually purchasing property online.


Outcome + Pitch

The winning project should be a mock up of a platform that would allow buyers to find real estate that suits their needs perfectly with regards to their desired area, budget and size. It should also include various info about the property such as:

  • What is its expected yield?

  • Rating on other websites (such as booking.com) if relevant

  • Who is run by? 

  • Who has invested in it?

  • Attractions in the area

  • Price cmparisons to other properties in the area

The product presentation should explain why it would get people make the purchase.

Supporting factors are customization to the client's needs, a wealth of relevant information, reliability and the feeling that "everyone is already doing it".

Livestone is looking to adopt such a platform and would like to invest in a winning feasable idea. Moreover, Livestone may hire the winning team to develop other tehcnological solutions for it.

If you win, Livestone will:

  • Invest in your product's development
