Airport Prefabricated Vehicle Pits

 

Pit specification: A 27m working pit with 3x2m equipment recesses linked with a connecting tunnel to a 17.75m VOSA pit which had a 2m equipment recess, shaker plate sumps, a split bed brake tester and an escape tunnel with a vertical ladder.

 

The problem: Extremely difficult ground conditions where 200mm of soil was covering sand which was deeper than the pits. Premier were unaware of this problem.

 

Solution: To use driven sheet piling – 80% of which was later reclaimed.

 

Outcome: Installation took a little longer than was originally estimated. Using conventional pit construction methods would have resulted in many extra days on site. The delighted client now has a smart water tight pit, that is an asset to his operation.
