”NPower, Rainton Bridge was 220,000 square feet over 4 buildings/three floors. The services contract value was approx. £4.5 million over a 25 week construction programme. The project scope comprised extensive modification to the existing Cat A (I would guess that some 75% of the main air handling plant was replaced!) along with new services for a kitchen/deli/comm’s room etc. The staff restaurant had an ‘exposed services’ approach which was executed in an exemplary manner. As with many fast track fit-out projects, the consultant information was perhaps less than perfect but Castle’s did not seek to take advantage of this. They has continuous senior management presence on site and in my opinion, adopted a positive and proactive approach throughout the project.”

The new College looks stunning and the build quality is better than university standard. From the beginning you and your team worked very closely with us, listened carefully to our plans and kept us fully informed on progress. We were keen that this build be exceptional and you have surpassed our expectations, bringing this technically difficult design to completion on time (in both phases) and within budget.

CBS is a company that cares about customer satisfaction, and it shows, We have greatly enjoyed working with you and your colleagues, all of whom are terrifically dedicated and talented people, and I hope that the continued success of the College means that we may be able to work with you again in the future, as greater expansion of the campus becomes possible.

Castle’s involvement on the project was continuous between August 2009 though to project handover in May 2010. Their primary point of client interface was with Bowmer and Kirkland, but they interfaced also with npower and the design team, in delivering mechanical and electrical services of very high quality. Castle performed extremely well in all aspects of the project and demonstrated professionalism throughout. They had a pro-active approach to problem solving and were an invaluable part of the construction team.

In respect of transparency of the financial accountability, and keeping the client appraised, Castle were on top of the job. They demonstrated a team approach in all aspects and were a pleasure to work with. Castle Building Services did what they said they would do and we would definitely work with them again.

We successfully achieved Practical Completion St Anthony’s, Somerleyton House, this afternoon.

This brings to an end 3 1/2 years of work which has seen the school completely transformed with a mixture of new build and refurbishment schemes. I would like to personally thank yourselves for all your drive and determination on the project, from way back when Richie was crawling under the floors of Westburn House through to Scott and the guys on-site completing the final phase. Could you also pass my thanks onto all of the sparkies and plumbers, who have worked on the cold face, day in day out to get it across the line.
