Completion of the Critical Stormwater Drainage Project in Riyadh, Saudi Arabia

Hassan Allam Holding is proud to celebrate a milestone by its subsidiary, Saudi Tunneling Company for Contracting (STCC), with the successful completion of the Critical Stormwater Drainage Project in Riyadh, Saudi Arabia, for the Riyadh Municipality.

The project involved the installation of seven parallel microtunnels spanning a total of 1,260 linear meters beneath a critical railway corridor—executed under demanding technical constraints, a highly compressed schedule, and with exceptional surveying precision to ensure the integrity of adjacent tunnels.

Completed through round-the-clock operations and a commitment to the highest health, safety, and environmental standards, this achievement reflects STCC’s specialized tunneling expertise and its ability to deliver complex underground infrastructure with the highest levels of quality and client satisfaction.
