Tunnel Ventilation and Subway Systems Engineering notes:

ACELA Consulting Engineers diverse experience and breadth of knowledge is found in all aspects of tunnel  and terminal systems design and assessment. This enables us to take an integrated approach to customer requirements and thereby advise the most appropriate and optimum system solution. An excellent example of our team collaboration was the Madrid Airport, EU renovation (illustrated above) which, with the help of one of our MEP collaborator,  George Nestor, PE and Eugenia Schweitzer, MSE of GNA Consulting Engineers, was a great success.

ACE experience extends from short pedestrian subways, to long tunnels for highways, railways and mass rapid transit subway systems.

ACELA's licensed engineers recognises the uniqueness of our customers requirements, our responses are therefore bespoke to the prevailing needs and individual circumstances. We routinely advise on entire tunnel system concepts, examining reliability, buildability, and maintainability as well as carrying out value engineering and evaluations of the economics of the mechanical and electrical systems to achieve the right balance between capital investment, operating costs and energy.

ACELA Consulting Engineers independence as an engineering consultancy further allows us to act impartially at all times and to give unbiased advice and assistance on all technical, operational and contractual matters.
