Work was halted at the One Chamberlain Square building when Carillion went into liquidation.
Now BAM, which recently secured the nearby Two Chamberlain Square office project at the site, will also finish off Carillion’s project topped out last December.
Once finished in early 2019, it will be handed over to accountant PwC for its Birmingham office relocation.
The majority of subcontractors who were working on the building will now return to the site.
Demolition contractor DSM has remained active on site at Paradise throughout the winter period maintaining the programme for Two Chamberlain Square.
Rob Groves, Regional Director of developer manager Argent, said: “Ever since Carillion went into liquidation on 15 January we have been working hard behind the scenes to ensure disruption to Paradise was kept to a minimum.
“Having BAM on board for the building along with remaining close to subcontractors and the supply chain means we are now able to move ahead with getting One Chamberlain Square completed as soon as we can.
“We will be very pleased to see contractors back on site later this month and the building progressing towards completion over the next year.”
Rod Stiles, Regional Director for BAM Construction in the Midlands, said: “Our work on Two Chamberlain Square started last month and having already taken on many of Carillion’s high calibre existing team we are now working closely with the existing supply chain to recommence construction on One Chamberlain Square as well.
“Our ability to work efficiently and fairly with the supply chain is one of the factors that distinguish BAM’s approach to collaborative construction and is an integral part of our ability to solve problems. Paradise Birmingham is a critical part of this city’s development. We’re delighted to be so intimately involved.”
At 1.8m sq ft, Paradise Birmingham will deliver up to 10 new flagship buildings, offering offices, shops, bars, cafés, restaurants and a four star hotel across 17 acres.
The Paradise Birmingham redevelopment is being brought forward through Paradise Circus Limited Partnership, a private-public joint venture with Birmingham City Council.
The private sector funding for Phase One and Two is being managed by Hermes Investment Management which has partnered with Canada Pension Plan Investment Board on the first phase of the development. Argent is the development manager.
