  Rees Apartment Retaining Structures 2005 - Present (Ongoing)

  Frankton Road, Queenstown (Subcontracted to SMG Properties Ltd)

  Project Manager – Jaron McMillan
  Site Manager – Philip Cave
  
  
  McMillan SDS were successful in tendering to construct the retaining walls for this high profile development – at the time the largest retaining wall in NZ (423 retaining wall piles, 567 ground anchors, 612 drainage bores, and associated test anchors, and inclinometers).
  
  The retaining wall piles ranged between 750mm and 1200mm diameter and to depths of up to 26mbgl.  Our Crawler track-mounted B125 Piling Rig was used for pile installation.  During piling average daily production was 4 piles, with 8 piles completed at peak production.
  
  The ground anchors ranged between 127mm and 200mm diameter with an average depth of 16.5m.  The average daily anchor installation rate per rig was 2, with 3 installed at peak production.  Installation allowed for the complete drilling, anchor installation and primary grouting.  Anchors were successfully test loaded to up to 945kN.
  This contract is currently on track and within budget.

  Newmans Lookout Piled Retaining Wall 2005

  ­­Buller Gorge (Subcontracted to Fulton Hogan Civil Ltd)
  

  Project Manager – Iain Haycock (100% tenure)
  Site Manager – Ja­ron McMillan (100% tenure)
  
  McMillan SDS were successful in tendering the constructions of the piles and anchors for the Transit Upgrade at Newmans Lookout on SH6 Upper Buller Gorge. The 625NB piles were installed to between 12.0 and 15.0mbgl using our 75 ton Casagrande TRD100 Drill Rig equipped with a Reverse Circulation (RC) DTHole Hammer (the largest of its type in New Zealand).  The ground conditions consisted of fractured massive Greywacke and Argillite.  During piling average daily production was 3 piles, with 7 piles completed at peak production – conventional piling techniques on a neighbouring section of the road had taken several days per pile.
  
  The ground anchor design was undertaken by McMillan SDS personnel and adopted high strength steel bar sourced from our European supplier.  Holes varied between 150NB and 200NB to depths up to 18mbgl.  Using one anchoring rig the average daily anchor installation rate was 3, with 4 installed at peak production.  Installation allowed for the complete drilling, anchor installation and primary grouting.  Anchors were successfully test loaded to up to 845kN. This contract was successfully completed on time and budget.
