Esher, UK – 19th April 2023: Keltbray, the UK’s leading specialist construction engineering and infrastructure services provider, today announces it has commenced work on the complex sub and superstructure packages on the Salisbury Square Development for main client The City of London Corporation, on behalf of Mace.

The delivery of the contract, valued at £73 million, follows on from the successful completion of the £10 million demolition and enabling works package by Keltbray, where sustainable circular economy techniques are being deployed to minimise waste and reduce the overall environmental impact of the scheme.

Work will include the installation of over 500 king post piles, secant piles, contig piles and bearing piles, construction of a new basement slab, core base and box, as well as four new cores, the formation of a reinforced concrete superstructure for the court building and a ‘listed building’ soft strip using ‘cut and carve’ techniques to retain key elements of the heritage structure.

The Salisbury Square Development will principally deliver a new, purpose-built 18-courtroom legal facility called the City of London Law Courts and an industry leading City of London police headquarters equipped to combat amongst other things, fraud and economic crime across the UK.

Chief Executive Officer, Darren James commented: “Keltbray is very pleased to announce we have secured the contract to deliver the major structural elements on Salisbury Square.  The contract is a significant step forward for Keltbray in extending our service offering further along the value chain, where clients are recognising the value in our integrated approach to self-delivery.”

Chief Operating Officer, Vince Corrigan, said:

“The award of the Salisbury Square contract is another important milestone in our ‘onekeltbray’ strategy and provides us with a fantastic opportunity to demonstrate our ability to deliver projects of this scale and complexity using our inhouse engineering expertise.”

Michael O’Hagan, Managing Director of Keltbray’s Built Environment division, said:

“With the redevelopment set to take a further three years, we recognise the desire for a highly sustainable build with carbon reduction and the circular economy are key drivers.  Therefore, where possible, we have developed a methodology to complete the works in the most sustainable manner.”
