Northern Group were engaged by Western Sydney Parkland Trust to undertake the construction of a one way slip lane access road into the Lizard Log Park, East Carpark off the Northbound carriageway on Cowpasture Rd Abbotsbury.
Construction works were in accordance with RMS specification with a client supplied project verifier certifying the works. Northern Group do not currently hold an RMS R1 prequalification however an exemption on this particular project was granted.
Northern Group tendered the project on an assumed pavement design based on the existing Cowpasture Road profile as existing ‘as built’ drawings were not available. The first of many hold points was to have an RMS project engineer and the client representative inspect the existing pavement profile to determine Synergy’s scope of works.
The existing road pavement was made up of the following;
50mm AC14, 150mm AC20, 150mm Lean mix concrete, 7mm single coat primer seal, 300mm unbound base and 300mm select material in upper formation all over existing compacted subgrade.
