• Requirement:
    Protect existing and new function centre

    Challenges:
    • This historic and popular tavern is positioned at the top of a large riverbank
    • The riverbank rises several meters above the river below
    • A substantial slip threatened the opening of the new function centre

    Challenges met:
    • Respected and established working relationship with Auckland council
    • EDC responded with a solid, tied-back timber wall design within 24hrs
    • Access was achieved from above rather than from the river

     Summary:
    Although access and time frames proved challenging, construction of the retraining wall, like the Tavern’s first function, went smoothly and without hitch.

  • Challenges:
    • Steep section
    • Irregular weathering profile of underlying rock and soils presented difficult foundation conditions

    Challenges met:
    • 7m Gabion retaining wall (welded mesh panels) built to support slope at rear of building platform

    Summary:
    EDC’s experienced Geotechnical team responded quickly, the end result was a substantial, attractive and well-engineered retaining wall providing the client with peace of mind.

  • A retaining wall design was required along the boundary for this multi-lot development.  EDC worked with the developer to establish the most suitable wall type for their project and then identify a low vibration installation method in order to minimise the risk of damage to adjacent property and also alleviate concerns being raised by nearby residents during installation.

    EDC produced a design package for the wall and carried out inspections during construction to ensure compliance.

  • Using the most up to date methods of assessment, EDC identified a high liquefaction risk in the shallow soils of this site.  We identified driven piling as the most economical foundation solution for this multi-unit Housing New Zealand development.  A pile design was produced by EDC’s geotechnical team who were proactive in leading the client through the process of a piling contract to completion using a foundation method that they had not previously used.

    Structural and civil design is also being provided by EDC, providing the benefit of an efficient and coherent approach to the client.

  • The site is located close to a river in an area of liquefiable soils and thus required a robust assessment of potential liquefaction related ground movement and a foundation solution to suit the assessment outcome and proposed retail building. The site had tight space constraints for the investigation. EDC worked with the client and landowner to ensure that sufficient on-site works could be undertaken. A piled solution was adopted to support the concrete ground floor of the retail building and EDC undertook all structural design works, which included Glulam beams, floor and columns.  Lateral loads were resisted by plywood shear walls and diagonal steel Reidbar.

  • The site is located in an area affected by liquefiable soils with a shallow ground water depth. The proposed buildings for Canterbury Rugby Football Union are long structures that could be prone to differential settlements.

    EDC undertook the geotechnical investigation and then worked closely with the design team and contractor to design a shallow ground improvement that ensured robustness and buildability through avoidance of excavation into the ground water table.  EDC then supervised and monitored the shallow ground improvement works to confirm that a first class product was constructed for the next installment of Rugby Park’s history.

    EDC’s collaborative working added value to the construction of this high profile project through a proactive role in communication and sound engineering input with the design team and contractor.

  • EDC provided a geotechnical assessment for an Importance Level 4 upgrade to a rural substation. The works involved a combination of test pits, boreholes, hand testing and percolation testing to enable soak pit design.  EDC provided detailed input to assist the structural design team to ensure that the substation will withstand the rigours of the New Zealand environment.

  • The development of a former industrial storage yard for residential purposes seemed to be too difficult for many developers until Horncastle Homes took up the challenge in 2015.

    EDC provided innovative Environmental and Geotechnical Engineering solutions to the site constraints, providing subsequent design and supervision that effectively remediated and strengthened the ground for residential living.

    The project has recently been completed and there are now 26 houses for Canterbury families to live in on what was barren land for more than a decade.
