Slipform Engineering – Gladstone Docks Silos

Project Overview

Capital Reinforcing was proud to support the construction of the new cement import terminal at Gladstone Docks, Liverpool, supplying all reinforcement for this major infrastructure development. The project, delivered by Slipform Engineering as Principal Contractor, involved the construction of four reinforced concrete cement silos, each with a capacity of 11,000 tonnes, forming a combined 45,000-tonne storage facility. Situated within an operational dock environment, the development plays a key role in strengthening the UK’s supply chain for low‑carbon cementitious materials, supporting future construction demand.

Features

Requirements

Capital Reinforcing was responsible for the supply of all reinforcement materials across the project, supporting both substructure and superstructure elements.

Our scope included:

  • Supply of reinforcement steel for pile caps, foundations and slabs
  • Reinforcement for four 20m diameter slipformed silos (41.83m high)
  • Reinforcement for ancillary concrete structures, including:
    • crane bases
    • dockside slabs
    • access structures
  • Coordination with the project team to ensure accurate scheduling and timely deliveries

Project Challenges

The Gladstone Docks project presented several key challenges typical of large‑scale marine and industrial developments:

1. Complex Dockside Environment

Working within an active port required careful coordination around:

  • restricted access routes
  • ongoing maritime operations
  • heavy logistics and lifting activities

2. Large-Scale Slipform Construction

The silos were constructed using continuous slipform techniques, requiring:

  • uninterrupted reinforcement supply
  • precise sequencing to match rapid vertical construction progress

3. Ground Conditions and Early Works

Extensive enabling works were undertaken, including:

  • deep excavations
  • installation of approximately 350 foundation piles
  • removal of obstructions and dock wall assessments

These factors increased the importance of early-stage planning and accurate material forecasting.

4. Programme & Logistics Management

With a precise timetable to stick to, maintaining consistent reinforcement supply was critical to keeping pace with the overall construction schedule.

Our Solution

Capital Reinforcing worked closely with Slipform Engineering and the wider project team to ensure seamless delivery throughout all phases of the project.

Proactive Planning

  • Early engagement to align reinforcement schedules with construction sequencing
  • Detailed call-off planning to suit slipform operations

Reliable Supply Chain

  • Manufacture and delivery of large volumes of cut and bent steel to programme
  • Flexible logistics to accommodate changing site demands

Key Highlights of the Project

Project Outcome

The Gladstone Docks cement terminal was successfully completed, delivering a high-capacity storage facility for cement and supplementary materials.

Capital Reinforcing played a key role in enabling:

  • The successful construction of four large-scale reinforced concrete silos
  • Delivery of over 3,000 tonnes of reinforcement to programme
  • Support for a critical UK infrastructure asset aligned with low-carbon construction goals

Conclusion

This project demonstrates Capital Reinforcing’s capability to support complex, large-scale infrastructure developments, particularly those involving:

  • high-volume reinforcement supply
  • technically demanding construction methods such as slipforming
  • challenging logistical environments

Through early engagement, reliable delivery, and strong collaboration, Capital Reinforcing helped ensure the successful delivery of a landmark project at the Port of Liverpool.
