Featured Project Special Projects

Peninsula Cycleway Project

Location:Portobello Road, Dunedin Date:2016
Type:Topographical Field Survey Services:Surveying (roading and seabed)

Dunedin City Council's plan for the extension of their cycle and shared path network down the Otago Peninsula has initiated a complex engineering project to widen Portobello Road and establish new sea walls.

As subcontractors to Lead Consultants GHD Ltd, Terramark were engaged to conduct a detailed topographical field survey of the road corridor and harbour bed and produce accurate 3-D topographical models to facilitate detailed engineering design.

Completion of this project has included the use of GPS and robotic total station technologies to gather topographical features, and has required carefully planned fieldwork, especially for the harbour bed, which could only be surveyed at low-tide.

Homer Tunnel

Location:Milford Sound Date:2010
Type:Topographical Survey Services:Surveying
Engineering

In 2010, Terramark worked with other consultants to the NZ Transport Agency, as part of a study into options to improve safety at the Homer Tunnel in Fiordland.

Working in an extraordinarily scenic while potentially hazardous environment, Terramark personnel undertook topographical surveying of the approach roads and tunnel portals, and assisted with 3 dimensional laser scanning of the full length of the tunnel interior.

Dunedin Wastewater Outfall

Location:Dunedin Date:2000 & 2007
Type:Construction Set Out Services:Surveying
Engineering

Dunedin's treated wastewater is discharged to sea at two locations at Waldronville and Tahuna. In 2000 and 2007 the Dunedin City Council upgraded these ocean outfalls by extending the pipelines further out to sea.

Terramark was engaged by the principal contractors to provide surveying services, primarily construction set-out, to monitor the alignment of the temporary pipe platforms and to ensure the positional accuracy of the pipelines on the seabed.

Waipori Power Scheme

Location:Lake Mahinerangi Date:2003 - Ongoing
Type:Shoreline Feature Monitoring Services:Surveying

In 2003, the Company was commissioned by TrustPower, to establish a survey monitoring network and collect data to detect any changes to the shoreline of Lake Mahinerangi, as a response to the lake level management regime.

This involved both GPS and traditional survey of beaches and shoreline, and hydrographic survey of parts of the lake bed.
