Todd Corporation, owner of natural gas provider Todd Energy, moved into the space of green energy by opening the largest solar power plant in Aotearoa at the time (mid 2021). Located in Kapuni, South Taranaki, this site now sees close to 6,000 photovoltaic (PV) panels generating enough electricity to meet the annual needs of over 500 homes.

On this project, BTW planners, civil and geotechnical engineers and surveyors were involved early on to help project decision makers with the complexities of a renewable energy project.

Together with nearby Waipipi Wind farm (between Pātea and Waverley), it shows commitment across the motu to scale renewable energy deployment and reach for better future outcomes together.

The River Road North, Ngāruawāhia subdivision, is an excellent example of a safe work site. This has been recognised with BTW and Sayer Drainage listed as a finalist in the Site Safe Awards. 

Like any project, collaboration is essential, and BTW pride ourselves in balancing the technical, operational, safety, cultural and environment elements of such projects. 

With the physical site challenges, and number of tasks occurring onsite, communication, flexibility and quick actions were needed for all facets of the job. Great people collaborating with easy lines of communication and daily presence with an onsite office were the key to the wellbeing and safety of all stakeholders. 

The multiple hazards associated with this site and task necessitated a separate Site-Specific Safety Plan (SSSP) and site induction process. These hazards and the associated hazard management included: 

• Contaminated soils – chemical, biological and archaeological 
• Deep trenches 
• Areas of high (perched) water table 
• Working in close proximity to the Waikato River 
• HiAb lift of wingwall to outfall at the river’s edge 
• Public on the ground near the workspace 
• Hot summer temperatures 
• Risk of environmental contamination 
• Personal stress on the crew to deal with multiple hazards 

BTW acknowledge the success of this project stage and our collaboration with Sayer Drainage. We can proudly say that all workers onsite could safely leave at the end of their working day and return home to their families.

BTW Company were engaged by EB Developments to manage this project from the due diligence stage through co-design in collaboration with mana whenua (Taranaki Iwi, Ngāti Tairi hapu and Oākura Pā Trustees), developed design, 3D rendering and visualisations, Geotechnical Engineering, Civil Engineering design to District and Regional Consenting.

The development name Te Ara Timata (the beginning of a path or journey), talks to the connection this development has to the coastline, extending on from other green spaces that together with the awa, create a pathways to the sea. It also connects with the purposeful nature of this development and moving forward with responsible design.

The design objective for BTW and the client was to align with the fundamental concepts within the National Policy Statement for Fresh Water 2020 primarily providing for Te Mana o te Wai whilst considering opportunities for improving open space and urban design outcomes. Due to the intersecting Wairau awa through the site, it was key to focus on the enhancement of water bodies by prioritising freshwater resource while recognising that protecting the health of freshwater protects the health and well-being of the wider environment.

The site has been thoughtfully designed by BTW’s qualified and experienced Environmental Engineers and Ecologists to enhance the ecological values for freshwater fish in the wider catchment and re-contouring of the stream banks to improve river values by restoring natural river function.

BTW are now tasked with construction supervision, certification, and survey to deliver this exciting project right through to the issue of titles.

Historical buildings are vanishing from our city skylines due to earthquake prone standards, housing shortages, modern designs or age and integrity of the buildings.

BTW’s Scan-to-BIM service is a great tool for building owners to digitally capture highly detailed data of their assets.

Asset owners can:

• Turn this data into virtual tours of existing buildings with Virtual Reality (VR).
• Produce 2D plans of the internal and external areas and dimensions accurately.
• Provide models to Architects, Structural Engineers and Designers for the design of retro-fit plans or extensions.
• Utilise the data for off-site pre-fabrication or project planning.
• Share the model with off-shore partners.

These images of the Cambridge Town Hall compare a highly accurate, surveyed 3D Point Cloud data vs the 3D Model generated by our in house geospatial field and office teams.

The level of detail modelled can vary from a simple outline through to the finer details of architraves, street furniture, wordings and materials.

If you would like to generate an accurate 3D model of your asset, get in contact with our BTW Geospatial team.

Pukekura Park Ecological Management work is ongoing and visitors to the park in recent times will have seen the desilting project in full swing. BTW played an important role in this project conducting a fish spotlight survey and a fish trap and transfer program for NPDC prior to the desilting operation commencing.

Over the three nights of monitoring our Senior Environmental Scientist counted:

• 78 Banded Kokopu in the tributaries upstream of the bowl lake, above the main lake and a drain running down the side of Brooklands Road. We found a range of sizes, including individuals that are <5cm long – indicating they are making it into the park from the Huatoki Stream in the whitebait runs.  These were spot lighted in about 150 metre of stream, so the Banded Kokopu are abundant.
• 9 Eel/Tuna, with 7 of them well over a metre long, mainly in main lake and fountain lake.
• In excess of 150 Koura! They are probably a good food source of the adult Banded Kokopu.
• 2 introduced Perch in the main lake, and
• A couple of giant goldfish.

Pukekura Park is an important and valuable asset for the Taranaki region, and being able to provide environmental monitoring services in this special place has been a pleasure.

Smart solutions and sustainable design

BTW’s involvement with Green School New Zealand started with advising on site acquisition. It was important that GSNZ chose a site where the school could tuck into the landscape and a site that had good road access.

Important next steps included a drone survey, environmental impact assessments and preparing resource consent applications.
Once consent was granted, BTW provided the civil engineering design for roads, carparks, stormwater management systems, wetlands, water supply, wastewater systems. And undertook surveying of buildings and facilities to ensure accuracy.

Survey data helped us to understand the opportunities. We then presented sustainable design options to Green School. This included swales and wetlands to manage stormwater and provide opportunities for environmental enhancement and secondary wastewater treatment systems using tiger worms to ensure a high level of treatment for wastewater prior to discharge.

Working with an innovative design and tight timeframes BTW had to compile a lot of information and assessments and communicate these quickly. Working collaboratively to find smart solutions was key.

Working on the Green School is a once in a lifetime opportunity and their philosophy is very much aligned with BTW’s. It’s about thinking big picture, challenging the norm and collaborating with like-minded people to achieve something special.
