River Engineering and Flood Protection
Projects undertaken include Flood Protection - Taramakau River for a significant farm operation in the lower reaches of the Taramakau River, Taramakau River Flood Levels Investigation, Waiho River Flood Levels, Waitangitaona River Flood Levels, Hokitika Township Flood Design Levels Investigation and Karamea River and Township Flood Design Levels Investigation.
INVESTIGATION, DESIGN AND CONSTRUCTION MANAGEMENT OF FLOOD PROTECTION SYSTEMS
A range of innovative and successful projects encompassing investigation, design and construction management of flood protection systems have been undertaken by Good Earth Matters for a range of clients in both the public and private sector.
Project works include the investigation design, procurement and construction management of the 10 year $40 million Waimakariri Flood Protection Project, peer review of construction methodology, procurement management and construction advisor for the $4 million diversion of the Manawatu River at Fitzroy Bend, Greymouth Floodwall Project, and the provision of specialist advice and construction management of the placement of 300,000 tonnes of rock protection in Whanganui at depths of up to 7 metres below water, the construction management of the placement of over 45,000 tonnes of protection works in the Hutt River.
All of these works have been completed on time, using innovate quality assurance methodologies and been either under or on budget.
CONSENTING OF RIVER MANAGEMENT WORKS AND FLOOD PROTECTION SYSTEMS
Projects undertaken include the global maintenance consent for the Lower Manawatu River, the Taonui Basin consenting, Anzac Cliff protection works consenting, a global maintenance and management consent for the Rangitikei River and the consenting of the Waimakariri Flood Protection Project.
Of significance is that all of these projects have been consented through hearings processes without any appeals to the Environment Court.
DEVELOPMENT AND DELIVERY OF PROJECT SPECIFIC PROCUREMENT PROCESSES
Good Earth Matters has been responsible for a number of project specific procurement processes including the procurement of the physical works for the $4 million diversion of the Manawatu River at Fitzroy Bend and the $40 million Waimakariri Flood Protection Project. The latter has involved some 20 to 25 individual physical works contracts of up to $4 million in value.
A critical feature is that all of these works have been delivered under budget on, or ahead of, time and to the requisite quality standards without any contractual issues or disputes arising.
DEVELOPMENT OF FLOOD WARNING EMERGENCY MANAGEMENT AND EVACUATION PLANS AND OPERATIONAL PLANS
The Flood Warning Emergency Management and Evacuation Plan prepared for managing risk on the Waimakariri River floodplain covers procedures and processes to evacuate people from about 100 properties and businesses on the floodplain as well as recreational users within the Regional Park which extends some 40 kilometres on the southern bank of the river. This is the most recent example of work undertaken in this area. One of the big challenges is keeping the plan allure and fresh to avoid complacency setting in.
In terms of river maintenance and operational plans, works undertaken include the review of Regional Council Operations Division Maintenance and Operations Manuals. This work includes ensuring best practice procedures for in-stream works are adopted, the regulatory framework is fully complied with and Health and Safety matters are fully addressed. Such work has been undertaken for Greater Wellington Regional Council and Manawatu-Whanganui Regional Council.
