The German-owned contractor said the scheme will be a showcase for its construction model which will “disrupt” the UK market.

Goldbeck has entered into a Pre-Contract Service Agreement (PCSA) with the local authority to fix the design and cost before signing a development agreement later this summer.

The council expects the new smaller building to cost around half the £100m estimated to refurbish its existing County Hall.

The scheme will harness Goldbeck’s innovative ‘turnkey’ integrated design and manufacture building process.

Goldbeck Group investment company Indigo is providing construction financing for the wider Atlantic Wharf project.

Craig Davies, Managing Director, Goldbeck UK, said: “The new County Hall to be built by Goldbeck UK for Cardiff Council at Atlantic Wharf will use our industry-leading construction model to deliver an operationally zero-carbon building.

“The new office space will provide a modern working environment more closely tailored to the council’s needs and have significantly lower operating costs than the current building it replaces.

“Because we manage all aspects of the project from architectural design to the manufacture of materials and assembly on-site, we ensure tight cost control, which is a top priority for Cardiff Council and vital to the success of the Atlantic Wharf area redevelopment as a future working and cultural hub for the city.”

The new Cardiff County Hall will cover 100,000 sq ft compared to the current 277,000 sq ft office building.

Davies added: “The UK potentially will be the biggest construction growth market in Europe over the next 10 years.

“But without a radical shift in approach by the British building industry, which is plagued by project delays and cost-overruns, the Government will struggle to reach its affordable housing and infrastructure development targets.

“Goldbeck aims to be a disrupter in the UK market and demonstrate how our flexible, integrated construction model can overcome the hurdles holding the industry back.”
