Road 16 Tunnels
We designed, managed, and executed The Drill & Blast operation for the construction of the new road leading to Jerusalem - the tunnels were excavated at the proximity of tens of meters to buildings and infrastructure. A complex project with many challenges due to nature, the urban environment, and the schedules.
Excavation Volume: app. 740,000 m³, 5.8 km.
Client: JV Shapir Engineering Ltd - Impresa Pizzarotti & C. S.p.A

The 5th Water Line
The 5th water line connects Jerusalem to the national water carrier and includes a 13km waterway tunnel done by TBM (Tunnel Boring Machine). We designed and executed The Drill & Blast operation for two sub-works in this project:
The junction opening between the TBM tunnel and the “Soreq” Adit tunnel; the TBM’s exit shaft at “Ein Kerem.”
Client: Oron infrastructure and construction, Zublin-Jager.
Past

"Carmel" Road Tunnels
Asaf led the Drill & Blast operation to construct Israel's first significant national road tunnel project. The tunnels were excavated tens of meters under the city of Haifa. A complex project with many challenges due to nature and the urban environment. Asaf did the design for an impossible section of the project, where the limitation was as low as a maximum charge of 1.2kg/delay. He managed to advance 3m/cycle on a 120m² face under this limitation in one shot. The excavation of the tunnels was completed one year ahead of schedule.
Excavation Volume: app. 880,000 m³, 9.2 km.
Client: CCECC (China Civil Engineering Construction).
