The smoke extract ventilation system was a part of a £1 billion investment to transform Manchester Airport and part of a 150% increase to the original size of Terminal 2 adding a further 81,000m2 floor area.
The project consisted of manufacturing, delivering, and installing a complete smoke extraction system and installing the free issue of plant equipment into the smoke system as part of the 2020 Terminal 2 extension at Manchester Airport. The work was carried out over a 16-month period using Exyte Hargreaves HFD-CE-SID fire rated smoke extraction ductwork and HFD-SID fire rated ductwork.
The main challenge in the project was in the physical size and weight of some of the items, as dimensions reached up to 5.2m x 2.7m in cross sectional area. Considering this and other variables, Exyte Hargreaves planned the site deliveries in accordance with site needs as just in time, as there was no facility for on-site storage due to such challenging dimensions.
The ductwork was designed to a maximum length of 1 meter, ensuring that the installation team could physically manoeuvre ductwork on site and could access any part of the ductwork in complete safety.
Exyte Hargreaves manufactured the external casing of the attenuators on the roof of the building, making it a compliant fire rated product. Large smoke extraction ventilation plenums were installed to serve the main lobby areas, with built in steelwork fan frames. Exyte Hargreaves innovative thinking and design allowed fans to be supported elsewhere, as immediately above the structural steelwork there was not enough load capacity to allow the weight of the fans to be supported conventionally.
The installation progressed exceptionally, meeting the schedule required by the client. This was possible due to a detailed upfront design coordination with site and logistical planning carried out by Exyte Hargreaves.
The installation team were recognised throughout the project for exceptional environmental, health and safety performance throughout the entire project duration, achieving top of the contractor’s performance league on multiple occasions.
