Projects

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.

Stage 1a for the Fryer Road Subdivision, located in Hamuranā on the edge of Lake Rotorua, is in its final stages, with titles released soon.

BTW have been working closely with C H Builders and Rotorua Lakes Council to deliver subdivision and regional consent, engineering design drawings and surveying services for this multi-staged development.

Lee Huang (pictured here) recently joined our Waikato surveying team from Auckland, after spending four years there post graduating from Otago University.

We’ll keep you posted as this project progresses and the remaining stages are completed.

BTW was involved early on in the development of the Ōtorohanga Store, providing a full suite of consultancy services to the client (NZ Farmsource) and the lead contractor (Livingstone Builders Ltd).

BTW Planners developed and submitted the Resource Consent application for the project.
Surveying services included scheme plan creation, boundary definition, construction machine control and building setout.

BTW’s Engineering Team provided full structural design of the new store and retaining walls, and civil site works, including onsite stormwater disposal and pavement design. This was developed in collaboration with the client, architect and contractor to produce an efficient, practical and ‘buildable’ solution.

During the construction phase, BTW were engaged has Engineer to Contract and provided contract administration, construction monitoring and quality assurance testing services.

For more information on the full suite of consultancy services offered by BTW’s multidisciplinary team, see below and click on the services icons to see more.

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.

BTW’s involvement with this unique and inspiring project, came about in part from our work with Project Mounga. It’s testament to BTW’s companywide passion to protect ‘our place’ and shows that with meaningful connection and smart solutions, great things can happen.

The Kaka Aviary was designed as a kitset, the parts premanufactured and all materials ferried into Abel Tasman National Park for construction onsite by DOC workers.

After its use in the Abel Tasman the Aviary will be dissembled and shipped to its next location.

To see the Aviary in use, and gain a little insight into this special conservation work, click here.

BTW are proud to have played a part in the largest release of NZ Kaka, with 24 birds safely housed in the Aviary and released in 2019.

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.

Providing intelligent and innovative modelling as a platform for design and construction.

BTW utilised the latest Trimble SX10 Scanning Total Station, with imaging, high speed 3D scanning and robotics to present a highly accurate capture of current state for the Huatoki tunnel, stream and surrounding area, including all above ground infrastructure and underwater structures.

By embracing these intelligent and innovative solutions, specialists in BTW’s surveying team were able to produce an accurate BIM from the captured data. This intelligent 3D model became a base for required design work completed by architecture, engineering and construction professionals.

Safety by design at the gateway to New Plymouth.

This complex development provides our community with a wide range of facilities whilst also safely cleaning up contaminated land at the entrance to New Plymouth.

The proposed commercial and retail complex on the corner of Devon Road, Smart Road and Katere Road, New Plymouth, will include rebuilding Aotere Pā from its remnant state, large format retail, visitor accommodation, supermarket, offices, food and beverage premises, cinema, other complementary specialty retail, and associated parking and landscaping on the ex-Ravensdown Fertiliser property.

The development is significant for New Plymouth from a public health perspective, in that it will remove deteriorating buildings clad with asbestos.  Contaminated soils within the site will also be remediated to provide for the new development. Furthermore, this gateway to our city will be greatly improved and the development includes significant road upgrades to Devon Road (SH3), Smart Road and Katere Road, to provide for safe and efficient access to the 1,200 onsite car parking spaces that will be available within the development.

BTW’s 3D scanning systems and surveying practice ensure a high level of precision – accurate results, fast solutions

Saving time, money and materials is made possible with a 3D scanning capture of the physical measurements of any object.

Services provided:

• BTW personnel added value with this innovative technology by reverse engineering a bearing ring.
• The 3D hand scanner measured the bearing ring in order to create a meshto an accuracy of 0.025mm. The mesh was analysed in specialist software and a CAD representation of the part was produced, which accurately reflects the as-built condition.
