New hangar within Manchester Airport

Bearing piles up to 12M

The challenge

Bearing piles were required to facilitate the construction of a new hangar within Manchester Airport for a valued Client. 

Piles were required to be installed through Sandy Gravelly Clay with a Mudstone socket to provide the load bearing capacity required for the proposed new hangar.

The design required needs to carefully consider the recorded rock strengths and varied ground profile to ensure an overly conservative design approach was not put forward as this would lead to longer than required pile lengths and increase the risk of damaging augers and reduced outputs as a result.  

 

The solution

Franki opted for the use of our Casagrande CFA piling rig to install the piles, utilizing the rigs high torque capabilities to ensure pile depths within the mudstone were met. Rock drilling CFA auger heads were used to achieve the desired pile depths into the mudstone rock layer.

2No. working pile tests were successfully carried out to verify and substantiate the design approach adopted and ensure that the pile embedment into the mudstone was sufficient to support the high loadings on the piles.

All works were carried out within a controlled environment within the Airport grounds, with our plant, equipment and deliveries having to access site through a live Airport environment.
