Allied Infrastructure

What Allied Infrastructure does

Allied Infrastructure Management Ltd is a UK-based specialist civil engineering contractor founded in 1994 (originally as Allied Drilling) and headquartered in Leigh, Greater Manchester, with a secondary Southern Office in Kent. The company delivers a portfolio of integrated services for operational airfields and infrastructure environments, including pavement repairs, civil engineering, asphalt surfacing, Rhinophalt surface preservation, AGL civils, line marking, joint sealing, cutting and drilling, site investigations, groundworks (via group company DJ Civils), and traffic management (via Franklin Infrastructure). Its core technology stack rests on proprietary application techniques — cold spray-applied Rhinophalt (HAPAS/CAA/MOD approved), FORMAVOID permeable sub-surface drainage, and PMB Polymer Modified Bitumen rail bridge joint systems — combined with self-delivered skilled direct labour and specialist plant.

The business operates an enterprise field sales model, securing work through long-term framework agreements (most notably the sole Lot 5 contractor position on the MAG Airfield Infrastructure Framework, 5+3 years from 2024), competitive tendering, and direct negotiation with airport operators, defence estates, Network Rail, and principal contractors including Tarmac, Balfour Beatty, Amey, and Colas. Revenue is generated through project-based contracts as principal contractor or specialist subcontractor, spanning short-notice reactive repairs to multi-disciplinary capital projects. Customer segments span Aviation (primary), Highways & Infrastructure, Ports, Defence, and Rail. The company holds ISO 9001/14001/27001 certifications alongside Network Rail principal contractor and National Highways SDF approvals.

In late 2025, Allied was acquired by DJ Civils, a specialist civil engineering group, and continues to operate under the Allied Infrastructure brand with existing management while benefiting from group-level resources. The company supports over 95% of major UK airfields, delivers 400+ projects per year across the UK and Ireland, and is led by CEO Ami Landau.

Allied is both a customer (PMB Joint Grip materials) and a competing contractor on airfield/highway frameworks.
• Dyer & Butler: UK civil engineering contractor specialising in airfield and aviation infrastructure, including runway resurfacing, AGL civils, and pavement maintenance for airports and defence clients. Direct competitor to Allied for MAG, BAA, and RAF framework work.

Broad incumbents

• Morgan Sindall Infrastructure: UK infrastructure contractor delivering rail, highways, aviation, and energy projects for Network Rail, National Highways, and airports. Comparable as a broad incumbent competing for the same public-sector frameworks Allied serves.
• BAM Nuttall: UK civil engineering contractor within Royal BAM Group, delivering highways, rail, aviation, and energy infrastructure projects. Comparable as a broad incumbent competing in the same tender pools for major UK infrastructure works.
• Amey Defence Services: Principal contractor on UK defence infrastructure (DIO) contracts, including RAF Brize Norton where Allied is a specialist subcontractor for surface preservation. Comparable as a broader defence-infrastructure incumbent that procures Allied's specialist services.
• Tarmac (CRH): UK's largest construction materials and contracting group; a principal contractor for major airfield and highway projects (e.g., Newcastle Airport runway re-surfacing with Allied as specialist sub-contractor). Comparable as a broad incumbent competing for the same frameworks at higher scale.
• Balfour Beatty: Tier-1 UK infrastructure contractor delivering highways, rail, aviation and defence projects including Network Rail contracts where Allied is a specialist subcontractor (PMB Joint Grip installations). Competes for major frameworks at much larger scale.

Regional players

• Lagan Aviation & Infrastructure: Ireland-based specialist aviation and infrastructure contractor delivering airfield pavement works, terminal civils, and surface treatments across the UK and Ireland. Comparable as a regional specialist competitor in Allied's overlapping geographies (Ireland, UK defence and airport works).

Others
