Auckland International Airport

Jonathan Nistor, Project Manager, Airport Development and Delivery, said “I wanted to pass on my congratulations and positive feedback to your teams survey fieldwork completion on a very difficult airfield operational area. The project went surprisingly smoothly in between difficulties with weather and stubborn manholes – and no operational issues with stakeholders”.

In Feb 2017, SSD was engaged by Envivo to complete underground utility surveying at the Auckland International Airport to help enable the planning stages for their Terminal Development project. Our techs did a great job in a very challenging environment, including liaising with project management to ensure the most efficient techniques and methodology to keep up with project schedules, involving public volume and safety, security, traffic control, surveying data collection, some extremely challenging man-hole covers, and many night shifts!
Surveying of total 4 months and great results.

Airfield team (ASO): “They were a really good bunch of guys to work with as they knew what needed to be done and had a good plan and I tried to accommodate their needs as best I could. No issues through the whole project and I would be more than happy to work with them again. Thanks again, and looking forward to the next stage of field works”.

Watercare WWTP

“We used the aerial surveying services for the second time on the same site to document the finalisation of construction of a project stage. Subsurface detection produced a hi resolution orthophotograph of the site that we had no issue using as a background on the general layouts of the site. The resulting A0 site layout drawing was displayed on site and quickly became a daily tool helping the operators and contractors preparing any works carried out on site – above ground or underground”.

New Round-about at junction of Waiuku Rd – Patamohoe Rd

Opus are helping Auckland Transport design and plan for works for a new round-about at this busy intersection and required a quick turn-around of the deliverables.

SSD took up this challenge and within five working days, supplied as-built plans of existing underground services using high-end GPR, EMI, RTK-GPS, Drone and Photogrammetric technologies.

Rosedale Waste Water Treatment Plant, Auckland

Watercare are planning on upgrading utilities across this plant.

Sub Surface Detection (SSD) provided a comprehensive solution by supplying as-built plans of existing underground services using high-end GPR, EMI, RTK-GPS, Drone and Photogrammetric technologies. We delivered layered PDFs, CAD files, GDB files and orthomosaic imagery of the site.

Bartley Consultants – Centreway Rd, Orewa

The client wanted us to locate services in the carriageway prior to road works.

A team of two GPR/EMI techs and one GPS/GIS tech achieved the survey within a day and we supplied as-built plans of existing underground services. Located services were overlaid on council aerial imagery as per instructions from the client.

NULCA industry training

In June 2017, all members of our GPR and EMI team underwent a rigorous NULCA training on best practices in GPR & EMI technologies. Very proud of all our techs who also took an assessment and successfully passed the course. This gives both, us and our clients the confidence that we are continuously providing the highest quality service possible, enabling SSD to achieve the AS5488 – 2013 Classification of Subsurface Utility Information (SUI) standards.

NULCA conference, Wellington

In May 2017 we attended the first NULCA (National Utility Locating Contractors Association) conference in Wellington. This was a great milestone for our industry here in NZ, and a great turn-out from both, around the country as well as Australia. Great steps moving forward raising the industry standards and creating certified locators.

Watercare Reservoir Concrete Scanning

One of our recent Concrete Scanning surveys was at the Watercare Redoubt Rd Reservoir to aid a Cassidy Construction project. With years of concrete cutting experience and the knowledge of the structure designs of prefabricated products such as Hollowcore, Double Tee, Unispan, Interspan flooring systems and their placements, this gives us a great advantage helping to interpret our hi frequency GPR.

Hunua 4 Section 11 – McConnell Dowell

For design and trench construction of Watercare’s Hunua 4 bulk pipeline along Ranfurly Rd, Epsom, we provided high spec deliverables including 2D drone aerial plan and 3D underground fly-through for our client. A great team effort enabling surveying to schedule and resulted in the detection of multiple unknown targets crossing the carriageway giving MD the opportunity to plan around these issues.
