An Aston engineering firm has landed a £10 million deal – the biggest in its history – to fit out a London hotel in time for the 2012 Olympics.

Building services provider J S Wright will fit out a new City Inn Tower of London in the capital after being selected by developer Laing O’Rourke.

The company will be providing all the eco-friendly mechanical services for the 584-bed high rise property, near Fenchurch Street Station.

A spokesman said the hotel, designed by Miller Hare Architects, was being built ahead of an expected influx of visitors to the city for the 2012 games.

The deal comes just days after J S Wright, which specialises in heating, ventilation and pipework, announced it had won three contracts worth almost £6 million in the capital.

The company is cashing in on a giant spending spree in the capital, with a total budget of £9.345 billion for the games and the regeneration of the East London area and billions of pounds more being spent by private firms.

Scheduled for completion in late 2010, the hotel will include a green roof terrace and a sky lounge and bar with views of the Tower of London and the financial district. J S Wright managing director Marcus Aniol said: “It’s a tremendous tribute to our highly professional team to have been commissioned by Laing O’Rourke to carry out our biggest-ever project for our first City Inn hotel.”

The firm will be working with design consultancy Faber Maunsell in providing a range of energy efficient, environmentally clean, and cost effective services including a geothermal heating and cooling system and a combined heat and power plant at the new City Inn.

It will also be fitting all the heating, ventilation, chilled water, above ground drainage, sprinklers, and hot and cold water services throughout the hotel and car park over a project period of 64 weeks.

Alan Blewett, project leader for Laing O’Rourke, said: “Having worked with J S Wright on two hotels and an office block in Southwark and two hotels in Reading, I am delighted to be working with the company again.”

The company completed what was then its highest value project last year by fitting out the County Hall Park Plaza, in London, which resulted in winning the 2008 Building Services M&E contractor of the year award.

The Birmingham Post reported last week that the company would net almost £6 million to fit out an eco-efficient housing scheme in Plumstead, a Premier Inn hotel in Greenwich and a housing development in Islington.
