Output
Laser scanning, archival photography and CAD
Geometria were commissioned by the Government of South Georgia and the South Sandwich Islands to survey the shore-based whaling stations of South Georgia Island to facilitate better long-term management, conservation planning, and wider interpretation of the sites. During the 20th century five shore-based whaling stations were built on South Georgia Island beginning with the establishment of Grytviken in 1904 and ending with the last station Leith ceasing operations in 1965. The stations are vast, complex, industrial sites that contain numerous buildings and structures - many with processing equipment still in situ throughout - as well as residential facilities and related detritus. Today the stations are in various states of disrepair and the condition of the extant buildings is poor with ongoing loss of cladding from steel framed buildings and partial, or total, collapse of many of the timber structures.

K021 – Scott and Shackleton’s Huts
Client
Antarctica New Zealand
Location
Ross Island, Antarctica
Output
Laser scanning, archival photography and CAD
Antarctica New Zealand Event K021 is a scientific collaboration between the University of Waikato in New Zealand and the University of Minnesota in the USA along with Bath, Hong Kong and Western Cape Universities and conservation architects Archifact. K021, which initiated research in 1997, has evaluated the deterioration of the Ross Island Historic Huts and artifacts of Scott and Shackleton, and their environs as well as having fundamental research aims. The key to the collaboration has been to use state-of-the-art multi-disciplinary scientific methodology. For the first time in the Antarctic, microbiology, wood chemistry, biochemistry, molecular biology and laser scanning technologies have been applied to the study of the deterioration of the huts. Our research goals include understanding and mapping the effects of biological versus non-biological deterioration at the huts; and understanding biodiversity and mechanisms of cold adaptation, proliferation and impact of Antarctic fungi and other microbes in pristine terrestrial locations and at the huts

Archifact/Auckland Unitec
Location
Apia, Samoa
Output
Laser scanning, CAD
Geometria were contracted to document the old Court House in Apia and provide data for a conservation plan, and CAD for Unitec masters students working on designing alternative uses for the building. The old Court House in Apia is a large wooden building originally built in 1902 by the German colonial administration, and extended between 1908-1912 using plans by architect Albert Schaaffhausen. It served as courthouse and administration building until 1914 when, at the beginning of the First World War, New Zealand troops took over the rule in Samoa and used the Courthouse as their administration building. From the time of independence in 1962, the Samoan Government used it as a Courthouse and as seat of the Prime Minister. The colonial-era courthouse had been empty since 2010 when a new building for the Ministry of Justice was finished in Mulinu’u, outside town.

Texas Creek Overlook
Client
Western Wyoming Community College
Location
Colorado, USA
Output
Laser scanning
The Texas Creek Overlook is a defensive structure overlooking a valley that was once occupied by formative period Native Americans ca 900 to 1500AD. It consists of a small fort constructed with layered rock walls and wooden support posts situated on top of a rock outcrop. The only access to the site is through a small entrance via a natural rock arch. Geometria were contracted to laser scan and model the structure as part of the ongoing maintenance and conservation of the site.

Cumberland Street Archeological Site
Client
Sydney Harbour Foreshore Authority
Location
The Rocks, Sydney, Australia
Output
Laser Scanning
Geometria were contracted to record the Cumberland Street archaeological site prior to the construction of a youth hostel over the site. The hostel is built on stilts above the site to allow the archaeological footprint to be retained within the development. The site was archaeologically excavated in 1994 with remnants of more than 30 convict era buildings dating back to the 1790s excavated. From the excavation evidence of the lives of over a thousand people who had lived, worked and died here over the previous century were recovered. The remains of their houses, and over 750,000 artefacts of daily use, have become an important resource for the study of the area.

Pu’ukohola Heiau
Client
University of Auckland
Location
Big Island, Hawaii
Output
Laser Scanning
Pu’ukohola Heiau is located in the South Kohola District on the big island of Hawaii. Kamehameha I built this massive luakini heiau in the early post-contact period (AD 1790-1791). The site is well preserved and a detailed body of information about the ethnohistory, and archaeology of the site have been complied. Geometria were contracted to laser scan the site to provide a detailed three-dimensional archive of the site. Pu’ukohola Heiau is an ideal structure for the application of laser scanning because of the complexity of the construction and scale of the site, and access to the structure, makes traditional surveying methodologies impractical.

Paradox Valley Rock Art
Client
Western Wyoming Community College
Location
Colorado, USA
Output
Laser scanning, CAD
Paradox Valley has been occupied for thousands of years by Paleo-Indian, Fremont and Anasazi cultures that have left behind village ruins, lithic scatter of stone tools, and a large amount of rock art. These locations may have been where shamans congregated and ceremonial rituals were conducted. Geometria completed laser scan surveys of a number of rock art panels and geologic formations to ensure that these significant sites are documented and can be further researched.

Barrenjoey Historic Track
Client
HLA Envirosciences PTY Ltd
Location
North Sydney, Australia
Output
Laser scanning, CAD
The Barrenjoey track and lighthouse laser scan surveys were undertaken to primarily record the Barrenjoey track prior to conservation and an upgrade to the surface. Laser scanning was chosen as the survey platform because the track consists of a narrow 1km long winding historic trolley track constructed in the1870s with hand hewn sandstone pavers. At the top of the track sits the Barrenjoey lighthouse and ancillary buildings, which were finished in 1881.

A detailed map of the mountain and archaeological landscape was made using a combination of aerial lidar, RTK GPS mapping and three-dimensional modeling. The surveys were undertaken to provide a detailed high-resolution map of the mountain and to use this data for archival and educational purposes and to reverse engineer a CNC milled model of the site for the Mangere Mountain Education Centre.

Fort Bridger Historic Park
Client
Fort Bridger Historical Association
Location
Wyoming, USA
Output
Laser Scanning, CAD
Fort Bridger was originally a 19th-century fur trading outpost established in 1842 on Blacks Fork of the Green River and later a vital resupply point for wagon trains on the Oregon Trail, California Trail and Mormon Trail. The Army established a military post here in 1858 during the Utah War until it was finally closed in 1890. Now run as a State historic park, Fort Bridger has number of original historic buildings and significant archaeological features and was surveyed to record both the extant buildings and archaeological evidence uncovered during excavations.
