Thomson–East Coast Line — T310 / T316

Overview

On contracts T310 and T316, STEC earth-pressure-balance machines drove Thomson–East Coast Line tunnels through the city centre — including sections beneath live infrastructure where every advance was monitored around the clock.

Our founder Kakita Naoki worked both contracts, adding STEC machines to a career already spanning Herrenknecht, Kawasaki and CREG platforms. That cross-platform fluency is one of the core strengths our crews offer.

Scope of Works

• EPB TBM operation in mixed-face conditions
• Ring building and grouting operations
• Machine maintenance between drives
• Breakthrough and reception works
