As UK Sector Lead – Data Centres, Cook brings experience from projects up to £600m in construction value, for international clients, including procurement and management of all major vendor equipment.

Cook spent seven years at ISG rising from a senior project manager operating in Finland to working for hyper-scale operators particularly in Belgium, Holland, and Denmark, rising to project director for the business.

At Sisk, he will spearhead operational delivery for data centres throughout the UK.

During the last decade, Sisk has built over 30 mission-critical facilities across Europe and continues to construct large data centre facilities, with projects currently under construction in Ireland and mainland Europe, for major international clients.

Cook will be working closely with the dedicated data centre team in Ireland and Europe to leverage their experience and network in meeting the needs of UK clients.

Paul Brown, chief operating officer for John Sisk & Son in the UK, said: “We are delighted to welcome Andy into our UK business and we look forward to working closely with him to ensure we achieve our strategic growth in the UK data market.”

In addition to his appointment, Sisk is also expanding its office network in the UK to better serve its clients.

The company has recently moved into office space in Central London in Farringdon and also engaged a long term project office in Leeds, reflecting the amount of work currently in Leeds and the significant pipeline of opportunities.

These offices are in addition to the company’s main regional bases in St Albans, Solihull, Warrington and Bristol.
