 Unlike traditionally built homes, prefab as many of us know that are assembled from components including walls and roofs that are produced in a factory in a controlled environment so that it can be delivered to site for assembling in a more efficient and safer way. This offers the opportunity to increase the productivity that being heavily impacted by this current crisis and even in a traditional way which prefabrication can serve as a solution as part of the solution. Here's the availability of artificial intelligence and big data really accelerate the whole process to make the prefabrication process smarter. One of the products we are developing, we are implementing is AI-based design and management toolkit for developers and governments to assess and deploy a affordable housing project using the prefab system we have. And we can use the algorithms to create standardized designs very fast so the resulting design can then be tested in a collaborative virtual platform across all the stakeholders in the value chain which means we can make wise decisions fast at the early stage, speed up the whole process and support a more collaborative approach for global partners across the value chain to work remotely and to control every step of the process more predictably.
