The Holcim cement plant is located in Bulacan region in the Philippines. The main site is located near rice fields and 400m from the Bakas River which separates it from the extraction site. During the storm floods, Bakas river floods the small valley between the extraction site and the main site.

In this context and in connection with Holcim company, Benoît Ribeiro, expert in conducting drone missions around the world for Lehmann aviation has used our post-processing services to establish a risk prevention plan to identify the flood impact on the industrial site. The 400 aerial images collected by Benoît Ribeiro were provided us from the Philippines (by internet connection) and we were able to quickly perform a series of simulations at different critical flood levels.
