Geometria provide a range of consultancy services from consent process and regulatory act advice to complete heritage project management.
Archaeological and Heritage Management
Peer Review and Expert Witness
Archaeological and Heritage Assessments
We undertake archaeological and heritage assessments throughout New Zealand to support our clients with their risk management, planning requirements and legal obligations. Archeological sites are protected under the Historic Places Act (HPA) 1993 and Resource Management Act (RMA) 1991 and often an authority to modify or destroy an archaeological site will be required as part of the consenting process. We advise clients on the regulatory authorities with which they will work and also assist clients with Iwi consultation for authority applications.
Archaeological mitigation includes monitoring or sites during development works, excavation and recording of archaeological features and material culture, buildings archaeology, and archival and as-built recording of heritage structures. This work is conducted under authority from the Historic Places Trust. We offer a complete mitigation service from small-scale residential excavations to large-scale industrial excavations and excavation project management services.
Analysis and reporting of archaeological finds is often a requirement of an authority issued by the New Zealand Historic Places Act to modify or damage an archaeological site. We provide a full suite of analytical solutions, both in-house and with our well-established network of specialist sub-consultants.
Historic research is undertaken both as part of the assessment process to provide background evidence to detail a site or property’s history, and to understand and corroborate archaeological evidence gathered from a site. We also provide research services for the Waitangi Tribunal to support treaty claims and work with local territorial authorities providing research for District Plan and local bylaw changes.
Peer review and Expert Witness
We undertake peer review of heritage related documents and assessments of environmental affects (AEE) on large scale infrastructure projects in New Zealand, and the preparation of expert witness statements of evidence for Environment Court and local territorial authority commission and plan change hearings.
Surveying and 3D Laser Scanning
Surveying is an essential part of modern archaeology and heritage management. Surveying includes site mapping, excavati surveys (surface topography, stratigraphy, three-dimensional artifact classification, feature distribution, and spatial analysis) and large-scale cultural landscape surveys.
High definition surveying (HDS) utilizes laser scanners to record objects of various scales at high resolutions in relatively short timeframes. Laser scanners have become an integral part of heritage recording, especially when recording large scale built heritage and complex elements. Laser scan surveys are used to create as-built surveys of heritage structures and detailed site surveys and are frequently used in 3d modeling and visualization projects.
Non-invasive geophysical survey techniques are used to locate subsurface archaeological material and features such as buried structural remains, occupation sites, burials, pits, defensive structures, and other material culture. Geophysical surveys are non-destructive and provide a rapid and cost effective means of identifying subsurface patterns and accurately locating and mapping subsurface features. They are an important precursor to an excavation as detailed site-specific information helps to identify key areas to maximize scientific returns.
GIS are used for the management and analysis of a disparate range of data including site surveys, topographic and tacheometric data, GPS data, archaeological data, cadastral and remotely sensed data. We utilise GIS for most of our projects and regularly develop GIS databases for clients.
CAD work underlies many of our projects from recording and drafting of heritage buildings and large-scale structures to detailed map documentation of archaeological and heritage sites. CAD data is largely derived from laser scan point clouds, photogrammetry, RTK GPS and total station survey.
3D Modeling and Interpretation
Three-dimensional modeling is used to visualize heritage and archaeological data. Computer generated reconstructions of past landscapes, archaeological features and other material culture allow us to view the past dynamically and across a broad range of media. Three-dimensional models and animations provide a number of education and research opportunities and aid the development and implementation of heritage management projects.
