Client. Gym Shark
 
Overview. Our client asked us to reinstall a Pigeon netting previously incorrectly installed by another pest control firm
 
Industry. Leisure
 
Project Name. Gym Shark Blyth Valley Industrial estate
 
Project Location. Birmingham, England
 
Brief / Challenge.
A 15 meter by 10meter Pigeon netting has been incorrectly installed on the roof at the client’s headquarters.
 
Survey Finding.
The Pigeons are roosting and nesting under the AC units on the roof. Due to health risks caused by the viruses/bacteria carried in the pigeon droppings the AC service company are unable to service the units. The wire to attach the netting has been secured on top of the metal cladding at the four corners of the roof, instead of securing the wire around the edge of the cladding every 200 to 250mm as recommended so insuring that the net does not bow and produce gaps for the pigeons to gain access. The net has been secured to the wire frame by 50 plus zip ties instead of using hog rings, for this size of netting I would assume that around 5000 hog rings would be required. The net has been hastily cut and resulted in the net being cut on a diagonal with the excess netting rolled up and tied. There are gaps around the bottom of the cladding where it meets the roof, these gaps are to ensure that the rain water follows away to the drains. These gaps have been blocked by a mixture of pigeon spiks, netting and metal weights producing mini dams that have pooled and caused the membrane of the roof to fail resulting in flooding.
 

The service we delivered.  
The works were completed over a four-day period. On day one the pigeon droppings had to be bio cleaned and removed before work could commence on the netting. Day two right angel guide rope brackets were secured to the cladding with self-tapping screws every 250mm. A 2mm galvanised was threaded through the guide holes and tensioned much like a guitar by 8-barrel strainers. Day three the spikes, netting and weights on the roof were removed and a 240mm by 10meter stainless steel cladding was installed in their place at 20mm off the roof top ensuring that the rain water will run away but Pigeons will not be able to gain entry. Day four the original net was cut down and reinstalled on the new metal wire and tensioned to avoid the sagging of the previous net.
