CHALLENGING CONDITIONS
A cofferdam was installed as a crucial preparatory step before using Direct Pipe©, creating a watertight enclosure to offer a stable foundation for the equipment, and provide a safe area for pipe assembly. The ground was excavated using a long-reach excavator, and a 1.35m deep concrete base was added.
The project location is a Site of Special Scientific Interest (SSSI), introducing environmental constraints that meant the pipe stringing platform and mud recycling compound was significantly restricted in size, to protect local wildlife and nature reserves.
Unforeseen changes in geology delivered a range of engineering and commercial challenges, with significantly harder ground conditions than expected and high volumes of water putting the Stockton team under pressure to maintain progress.
The site location sits within an existing flood plain that floods annually over the winter months, preventing access to site, squeezing the construction programme into the accessible months of the year.
HANDS-ON PROJECT MANAGEMENT
Due to the critical nature of the crossing, Stockton participated in regular planning reviews with the client and subcontractors. Stockton established a safety-first culture on site by enforcing thorough site inductions and regular toolbox talks for all personnel.
This full project management capability means Stockton is able to manage complex, high-risk projects and deliver them to industry leading quality and standards, in a safe and practical manner, becoming a contractor of choice across the sector.
Throughout the project, Stockton continually worked with the Environment Agency to to ensure safety and environmental compliance.
