Overview
We successfully completed the installation of over 220 bored piles, with diameters ranging from 600mm to 1050mm and depths reaching up to 19 metres. These piles formed the critical foundation system for multiple key structures, including station buildings, train collision barriers, and retaining walls. The works were carried out in a complex rail environment, requiring strict adherence to safety protocols, precise positioning, and coordination with other construction activities. The variety in pile sizes and depths was carefully engineered to meet varying load demands and ground conditions across the site, ensuring long-term stability and structural integrity for all supported elements.
Challenges
The project was delivered under challenging conditions, including tight access, low headroom, and the logistical constraints of working within an active rail corridor. These limitations required the use of specialized low-clearance equipment and carefully planned methodologies to ensure safe and effective execution. Due to the proximity to live rail lines, all critical works were scheduled during designated rail closures, demanding precise coordination and strict adherence to timeframes. Our team's ability to operate efficiently within these constraints ensured that all works were completed safely, on schedule, and with minimal disruption to rail operations.
Solution
Piletech deployed specialised low-headroom equipment capable of drilling 14m deep piles under just 6m of clearance. A combination of pendulum drilling machines and fixed mast rigs allowed rapid, high-volume installation within limited access windows.
