Ivory Lane Boardwalk

Project Description

The Ivory Lane boardwalk provides the link for cyclists and pedestrians to and from the Story Bridge/Bowen Terrace, City Reach and New Farm Riverwalk.  The existing elevated timber structure had deteriorated and required replacement.  The new boardwalk provides a more durable, wider walkway for pedestrians and cyclists with the use of fibre composite technologies.

The scope of works included:

  • Demolition and removal of the existing timber boardwalk structure;
  • Excavation works to remove dry stacked boulder wall and create access for piling works;
  • Design and installation of 114mm dia. micropiles;
  • Installation of 260mm dia. micro
  • Installation of soil nails and shotcrete to stabilise steep batters
  • Concrete Retaining walls, abutments, pile caps, car park and footpath slabs;
  • Design, supply and installation of permeable block retaining wall;
  • Balustrade and fencing;
  • Design and construction of fibre composite boardwalk structure with Lamideck composite decking;
  • Landscaping;
  • Path Lighting

 

Project challenges:

The team faced numerous challenges to complete the walkway replacement project due to the confined access and steepness of the site, located in a narrow easement between hotel and apartment buildings.   The existing walkway and old, dry stacked boulder wall had to be carefully demolished.  A temporary pile wall, soil nails and shotcrete were then installed to retain the bank while access was created below for the structural foundations.  The fibre composite walkway structure was prefabricated and transported to site in four spans before being craned into place.

Due to the surrounding hotels and apartments, working hours had to be limited and vibration monitoring was undertaken to ensure the impact of the project was minimised as much as possible.
