About Jonas Colonia

My educational background with Civil engineering, but was pulled into Project Management due to the work I did on construction sites. I have 13 years of international experience working with a General Contractor in the construction of Mid-rise buildings, Commercial High rises, and Heavy Civil projects.My recently completed project was a Transit Infrastructure in Singapore as part of Downtown Line 2. It was the Bukit Panjang Cut and Cover Subway Tunnel with Station. This project had a retrieval shaft for a Tunnel Boring Machine (TBM) from adjacent stations as well. It was located in a populated area with heavy traffic. We first created new temporary roads then divert the traffic. This provided us with the space to execute open mining at the middle of the roads. We supported our excavation with secant bored pile walls and horizontal steel and concrete struts in stages during excavation. Once we reached the final excavation level we cast the box tunnels, provided waterproofing on the exterior and backfilled. There were a lot of challenges back then but one of them was removing the concrete struts cut into 5-ton pieces which were 20m below ground using cranes in the middle of the bustling city street. And being in the middle of the road, safety was paramount. Coordination and communication were key to the success of the project. Finally, in Dec 2015 the whole Line was opened to the public.On my free time, I love spending it with my family. We love to travel and expose ourselves to new food and culture along the way. I love roller coaster! I wanted to try bungee jump once but my wife wouldn’t let me (PS: please don’t tell my wife)
