Medallion has filed a breach of contract claim against InfraPartners in the English High Court after the contractor allegedly failed to complete the construction of a data center in Lagos, Nigeria.

The Nigerian company – which in 2023 became part of Digital Realty – is seeking a total of $15.5m in repayments, damages, and other losses. InfraPartners disputes the allegations.

According to court documents filed by Medallion, seen by DCD, the company entered into a $35m agreement with InfraPartners in June 2024 to build a modular data center near Lekki.

The LKK2 project included the construction of a one-story data hall of approximately 1,260 sqm (13,500 sq ft) with 1.96MW IT capacity, an office building, a car park, and storage for fuel.

Under the agreement, the data center would have been manufactured at InfraPartners’ facility in Romania before being delivered in modules to the site in Nigeria, where they would be assembled. InfraPartners was required to complete the works by 28 January 2025, Medallion claims.

However, Medallion alleges the initial modules had reportedly arrived late, incomplete, and out of order in late 2024, with the project still far from completion by the summer of 2025. The company claims the data center was suffering from water ingress and other defects, and InfraPartners had stopped paying its subcontractors.

Medallion said that the water leak damage was due to InfraPartners’ “failure” to make the works water and weather-tight.

It claimed that concerns about leaks were first raised in February 2025. A few months later, Medallion’s health and safety consultant, Kevron, issued a ‘stop works order’ citing unsafe conditions after the water leaked into areas with live electrical components.

Medallion said that although InfraPartners tried various solutions to fix the problem, they all allegedly failed.

The data center operator said that an Excel file provided by InfraPartners in August 2025 showed the company owed “significant sums” in unpaid invoices to its subcontractors.

Medallion claimed that InfraPartners didn’t provide proof of payments to its subcontractors “despite repeated chasing.”

It also claimed that it had been approached by subcontractors “who threatened to withdraw resources due to non-payment.”

“Meanwhile, the works on site had slowed to such an extent that on 3 September 2025, Turner & Townsend [Medallion’s employer’s representative] recorded that there was a “state of emergency” on the project,” Medallion said in the court papers.

During a virtual meeting on 10 September 2025 between the companies’ management, Medallion alleged that InfraPartners acknowledged that “its financial constraints” meant it wouldn’t be able to pay its subcontractors and suppliers for items critical to the project.

Two days later, Medallion claimed it wrote a letter to the contractor requesting a recovery plan and warning that failure to continue with the project would constitute a serious breach of contract.

Medallion claimed that it didn’t receive a response. It terminated the contract with InfraPartners on 27 September 2025.

The company filed a claim against the contractor in the High Court in December 2025.

Medallion said it appointed other contractors to complete the project and fix the alleged defects. The data center remained unfinished as of March.

Digital Realty and InfraPartners declined to comment. Medallion’s lawyers were approached for comment.
