Morgan Sindall has topped the contracts league for July after its Overbury fit-out arm secured a record-breaking job.

The fit-out contract at Citigroup’s tower at Canary Wharf is estimated at around £300m and will see the modernisation of the 45-floor skyscraper which sits at 45 Canada Square.

Known as Project Saturn, the contract includes major building services infrastructure replacement, structural and façade works and extensive refurbishment of lifts.

Securing the contract also saw Morgan Sindall jump from sixth to second in the annualised league table for orders secured over the last 12 months.
