Initially Imperial had decided not to get involved with the build of this project although due to cost constraints we were approached by the client to assist with the cost plan and advise the best value we as a business could build areas that were firm in design and agree associated budget figures for areas where the scope was not defined.
After a few negotiations and presentations, the client decided that that would like to pursue the project with Imperial and a scope of works was agreed between both teams. Imperial’s Scope involved installing all main dedicated ductwork systems, AC Systems to all main IT rooms, full selection of all plant dedicated to all the air systems in line with the design by the consultants.
Early on it was clear that provisional spacing and allowance for main plant provided by others would not work with the constraint and IDSL worked closely with the dedicated cad team detailing and modelling in plant and systems in advance of co-ordinated drawings. Decisions were made with the main contractors to advance main areas before full design was complete to reduce impact of design that was planned to follow once final decisions were made. These along with the decisions on main plant selections and allowance for capacity emant that no items of plant had to be changed upon completion.
IDSL decided early on that all main ductwork systems would be fully tested to provide a very high level air volume circulation and also tested the ductwork far in advance of its running pressures to allow selection of fans and plant to be optimised to its full potential with lower running costs and opportunity for increased volumes. Completed test and witness sheets demonstrated that overall the whole systems and leakage rate was of a very high standard.
All Air Handling Units were delivered with fully operational controls removing workload on site that normally sees control interfacing completed on site. All systems were factory and site tested to provide further compliance to the quality of installation and remove risks at a later stage on the project.
Part of the design requirements involved a dedicated system that was designed to provided air movement, without shadows, dehumidification and lighting control over the main pitch at the football ground when the pitch was placed in a stored state due to other activities planned for the stadium.
Many areas were to remain on show and the ductwork was to be used as a feature in and around hospitality. Meetings were important to understand fully what was required in these areas and nonstandard colours were used provide a natural look to the systems.
