Berth 35, Port of Southampton

Project Objectives

Ryebridge delivered the phased refurbishment of approximately 4,000m² of operational quayside pavement at Berth 35, Port of Southampton for Associated British Ports. The scheme involved pavement reconstruction, removal of embedded infrastructure, installation of new ducting and service corridors, drainage improvements, surfacing works and associated civil engineering infrastructure. Works were delivered in two carefully planned phases to maintain unrestricted port operations and vessel movements throughout the construction period.

Project Works

The quayside itself is a suspended slab with crane rails installed on the top, infilled at a depth of 140mm to ensure a level surface, and dates back to more than 100 years ago.

With around two to three boats docking each week for periods of between one and two days, the Ryebridge team had to stand-down during tie-up, and remove permanent fencing to allow access to the quayside, replacing it with Heras fencing for the duration.

Because works were being carried out on a suspended slab Ryebridge could not use the usual big diggers and concrete breakers. The solution was to sawcut the concrete 100mm either side of the crane rails, and then use handheld machinery to break up the concrete before cutting the rails into pieces and removing them.

Only then could a concrete planer be used to remove the infill off the slab in preparation for Tarmac to be laid.

Programme risk was managed through a phased delivery strategy that allowed port operations to continue throughout construction. Work zones were segregated using temporary fencing, with operational access routes maintained at all times. Ryebridge coordinated closely with ABP operational teams to manage vessel berthing schedules, temporarily modifying site arrangements during ship arrivals and departures. Early surveys, work package planning, and regular coordination meetings ensured efficient management of stakeholder and operational interfaces.

Innovation and Best Practice

The works were completed on time and on budget with 100% safety record.

All works were completed with no disruption to port operations, with the designated areas cordoned off with secure fencing.

All required machinery was mobilised and maintained on site, and a dedicated team oversaw health and safety, quality and progress throughout the works.

Ryebridge maintained a collaborative working relationship with ABP through regular progress meetings, programme reviews and proactive interface management. Early engagement with operational stakeholders ensured construction activities were aligned with berth requirements, while change control and risk management processes enabled issues to be addressed before impacting programme delivery.

Experience of working in port environments and managing a significant volume of subcontractors is essential. In addition to this, gaining such knowledge over time spent completing these works has reinforced our ability to plan for things that would not be expected.

Ryebridge is always solution-focused, adaptable and client-centric.

Moving forward

The success in this project reinforces our commitment to early engagement and a close

partnership with our clients. Our clients can be certain that we have their objectives at the centre of what we do.

In this particular project we are extremely proud that our ability to build relationships and add value to our clients is evidenced successfully throughout, particularly in reducing the time of the works.
