ABP, Brett and Tarmac’s Sizewell C hub: logistics and materials notes for engineers
Reviewed by Tom Sullivan

First reported on New Civil Engineer
30 Second Briefing
ABP, Brett and Tarmac are developing a tri-modal (road, rail and marine) logistics hub at the Port of Ipswich to feed construction materials to EDF’s Sizewell C nuclear project on the Suffolk coast. The hub will consolidate aggregates and cementitious materials for bulk shipment, reducing HGV movements on local roads by shifting high-volume loads to rail wagons and coastal vessels. For civil and materials teams on Sizewell C, this signals a tightly controlled supply chain with centralised quality control and stock management for concrete and backfill materials.
Technical Brief
- Similar tri-modal hubs are increasingly adopted on UK megaprojects to de-risk aggregate and cementitious material continuity.
Our Take
Associated British Ports’ separate £500M Solent Gateway 2 procurement notice in our coverage signals that ABP is scaling multiple major logistics platforms at once, which is likely to standardise its contractor frameworks and digital systems across both the Port of Ipswich and the Solent.
Within our UK Infrastructure coverage, ABP appears more frequently in port expansion and multimodal hub stories than other private port operators, suggesting that its role in projects like Sizewell C is part of a broader strategy to anchor large construction supply chains to its estate.
For materials suppliers such as Brett and Tarmac, being embedded in a dedicated Sizewell C hub at the Port of Ipswich positions them well for follow-on work on other ABP-led logistics schemes, as ABP’s expansion pipeline increasingly favours long-term, integrated tenant-operator relationships.
