Between 2010 and 2013, several JEB employees participated in the Cambodian Railway Rehabilitation Project: 163 kilometers on the southern line from Phnom Penh to Sihanoukville, 48 kilometers on the northern line from Sisophon to Poipet, and 32 kilometers from Phnom Penh to Bat Deng.
The southern line railway is a 1-meter narrow gauge, single-track line rehabilitated with concrete sleepers. The northern line was rehabilitated at a low cost by keeping the existing steel sleepers.
Jeremy lead six topographic surveyor teams and managed the project through all design, earthworks, structural works, track installation, tamping, and as-built phases.
