Smart Concrete

Design the new generation of concrete sensors.

Background

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?

Possible professional background and expertise of team members

  • Electronics (sensors, antenna, transmission, battery...)

  • Programmers (online remote access to measurements)

  • Business model of IoT

 

A list of suggested information sources and recommended reading in preparation for the hackathon will be sent to the participants who choose this challenge.

Judging Criteria

  • Cost of the solution

  • Feasibility

  • Range of data transmission

  • Expected lifespan

  • Company or team’s experience in monitoring solutions

 

Smart Safety

Develop new ways to save lives by preventing falling from height on construction sites.

Background

Falling from heights on construction sites is the most common cause for accidents on sites.

In 2018, the number of these accidents in Israel was double that of all other construction sites accidents combined and accounted for 60% of the death incidents and 71% of severe injuries.

 

Challenge Description

 

To drastically reduce the number of fall from heights accidents and injuries on construction sites, caused by the fall of workers or tools, through innovative and effective technical solutions. 

Ideally, the proposed solutions would allow workers to operate freely without a restricting harness or a tool-bound cable.

Solutions could address the prediction of accidents using AI and big data.

Outcome + Pitch

A design for a product that answers the challenge, including a virtual prototype that will be presented to the judging committee at a live pitch event.

Possible professional background and expertise of team membersThe competition is open to anyone passionate about construction tech and solving the burning issues of on-site and worker safety. Ideally, participants will have a skill set from the following fields: construction, technology, product development, engineering, or any other relevant field.

Judging Criteria

  • Technological feasibility with an emphasis on time to market and on site application readiness.

  • Financial feasibility with a solid business model, pricing plan and scalability

  • Versatility and ability to adapt to global market needs, different work sites and conditions

 

Smart Selling

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

Background

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 comparisons 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 feasible idea. Moreover, Livestone may hire the winning team to develop other technological solutions for it.
