HKAA Project P3801 - Installation of fabricated air valve tees in a pressure rising main at Hong Kong Airport

The Midfield Concourse is located to the west of Terminal 1, between the two existing runways at Hong Kong International Airport. The project is a five-level concourse with a total floor area of 105,000Sqm combining 20 aircraft parking stands including two A380 stands.

Over 11km of Mill-Pro M90 ES SDR 21 PE100 RC pipe was installed for this DSD project.  AECOM burial design used imported graded backfill with a geo-textile barrier to prevent fines being washed away.
