![]() ![]() Part of critical bioremediation work -Dredge and excavation work will include removing approximately 40,000 cubic meters of material from the canal and separating the material into two separate decontamination sites.This 3D picture on the on-board screen gives the operator a clear visual of where he needs to position the dredge head underneath the water with a goal of removing material down to the green line but not lower than the red line. Real-time visualization and simplifying a complex process - Using Trimble Marine Construction software, the team set maximum over-dredge depths, represented by red lines and the design depth (bottom of toxic layer from the core sample survey) as green.Dredge work on time and on schedule - Several weeks into the project, the team has completed some 580 meters of dredge work for the 5.1-Kilometer section of the canal thus far.Trimble Marine Construction (TMC) Software and GCS900 Grade Control System for Excavators and the pre-dredge survey used Trimble HYDROpro software, Business Center- Heavy Civil Edition (HCE), and iBASE (real Time RTK Corrections for New Zealand running on Trimble Pivot platform). Because of the complexity of the dredging required, coupled with extensive decontamination work ,NZPGS,s engineering team turned to SITECH NZ and Trimble Marine for help with positioning and 3D real-time visualization of work. Working under a consortium headed by EnviroWaste Services Limited, NZPGS was hired for a large-scale canal remediation project for Whakatane's Kopeopeo Canal in New Zealand. The company is technology driven and delivers a broad range of seismic and reservoir services, including acquisition, imaging, interpretation, and field evaluation. OverviewĬustomer Profile: NZPGS delivers specialist environmental dredging services, flood management, equipment rental, sales and specialist project and support services to the New Zealand and Pacific markets. ![]() Real-time positioning and visualization from SITECH NZ and Trimble’s Marine Construction Software (TMC) and positioning technologies, help contractor tackle landmark dredging and remediation project. ![]()
