Mechanical Services

Our Mechanical Services division was introduced to form a stronger team here at GA, providing our clients with a fully coordinated and integrated Building Services solution.

We acknowledge that mechanical building services are vital to the effective operation of all buildings. From air conditioning and ventilation to public health works, it is the building services that provide the comfortable, safe and productive environment in the places we live, work and spend our leisure time. As these services become more integral to built environments, so we have become increasingly integrated into the building design and construction processes.

The management and staff of GA mechanical pride themselves on offering a practical and common sense approach in providing safer, better, faster and more effective solutions to the design and construction process, bringing best value to our clients and at the same time minimising risk.

We aim to deliver every project to the highest quality in a professional and efficient manner ensuring health and safety is always at the top of our agenda. We understand that ‘time equals money’, therefore we work with our clients to ensure that all projects are delivered inline with the programme and on budget.
