Threadneedle Street Air Handling Units Replacement Project

Tender description

The existing ventilation system in Threadneedle Street comprises of two primary main supply air handling units and twelve secondary air handling units, which supply tempered air to the occupied office areas via a series of services tunnels and builders' work shafts. This plant and equipment was installed in 1987 and has now reached the end of its economic lifecycle and requires replacement. This project will replace the primary and secondary air handling units with new. This will include all associated plant and equipment within the confines of the air handling unit plantrooms such as, chilled water pipework, low temperature hot water pipework, building management main control panels and field devices, plantroom ductwork distribution systems, ductwork ancillaries such as attenuators, fire dampers, volume control dampers, and all associated builders' work in connection.
