Temporary Ventilation & Air Quality Monitoring

EKFB is seeking to appoint a sub-contractor to supply and/or install the Temporary Ventilation and Air Quality Monitoring, to allow for a healthy and safe environment whilst constructing 3no twin-bore cut-and-cover tunnels. The tender will be considered in two lots:

Lot 1: Supply of all equipment and accessories for the temporary ventilation and air quality monitoring systems for the 3no Green Tunnels

Lot 2: Installation, maintenance and removal of the temporary ventilation and air quality monitoring systems in the 3no Green Tunnels

The temporary ventilation and air quality monitoring systems include, but are not limited to, fans, anemometers, gas detectors, smoke detectors, diesel particle matter detectors and volatile organic compounds detectors.

The temporary ventilation and air quality monitoring systems should be in service from the commencement to the completion of the MWCC activities inside the tunnels. For that reason, the installation should be done in multiple visits, following the construction sequence of the tunnels. These visits should be short and efficient to ensure the disruption of the other activities is minimum.
