CIAL THL Yard Extension Civil Works

A need arose for Christchurch International Airport Ltd (CIAL) to increase the size of the vehicle parking area at the rear of the existing building by 11,000m² located at Mustang Park.  Works included the establishment of a storm water drainage system and discharge to meet CIAL Storm water Discharge Consent requirements, paved car parking and perimeter fencing. 

Mustang Park had areas of remediated landfill and soil testing has shown low levels of land contamination including asbestos fibres. Earthworks (undertaken by Dormer Construction as sub-contractor) involved stripping topsoil and carting to the stockpile, excavating down to subgrade and carting material to the stockpile.  Any contaminated material had to be carted to a separate stockpile as instructed by CIAL and the location recorded for future reference. 

AP65 sub-base metal was then carted in and placed to the required level.  All the earthworks were undertaken using a GPS machine controlled D6 Dozer which proved to be very efficient.

Drainage was undertaken by Isaac Construction which included soakaways, concrete protections slab over soak pit, manholes, stormwater pipe and sumps equipped with Enviropods.  Kerb and channel were installed after the drainage work was completed.  Once all the drainage, kerb and channel were completed, timber batten was installed followed by the metal base course layer over an area of 16,000m2.  A 2-coat chip seal was ten applied over the entire area.
