Overbury has taken over the fit-out of the 350,000 sq ft India Buildings in Liverpool from Caddick Construction, the third contractor to work on the project this year.
The grade two-listed city centre block is set to become a regional super-centre for HMRC, which is relocating staff from Graeme House, Raglan House and Imperial Court in Liverpool, and The Triad in Bootle.
Legal & General is the owner of the building, having acquired the site in 2017 for £125m from Shelborn.
The refurbishment project has already seen a series of complications and delays, after the discovery of nearly 400 tonnes of asbestos and additional works which required specialist planning permission.
Styles & Wood was delivering a £38m fit-out contract, which was terminated in September, with Caddick Construction appointed to take over.
At the time Styles & Wood said a “dispute has arisen” and the company was seeking legal advice, describing the termination of the contract as “wrongful”.
When Caddick took over, a fresh construction timetable was announced, with completion scheduled for summer 2020.
Regarding the switch in contractors, a statement from Caddick said: “Due to delays experienced prior to Caddick Construction being involved in the scheme, the original intent to have a contract for refurbishment/Cat A fit out and a separate contract for Cat B has now changed. The contracts will now be combined and undertaken by Overbury.
“Caddick Construction is currently working with the new developer Legal & General to facilitate and assist in the transition of Overbury taking over the project.”
A spokesperson from Overbury said: “We are working in partnership with Legal & General and HMRC to deliver their new regional centre at India Buildings in Liverpool.
“We are currently reviewing the works to confirm time-frames for the completion of the whole project. Caddick is also working with us in the early stages to help achieve these goals.”
