Large anti-pigeon net

Installed pigeon netting

Covering the HVAC (Heating, Ventillation and Air Conditioning) plant on the roof, this net prevents pigeons from nesting near the air intakes supplying fresh air to the offices below. This maintains the quality of the air supply and makes servicing the HVAC systems a less hazardous and cheaper procedure; cleaning guano off switchgear and filters is expensive and time consuming.
