Archaeological Research

Commonwealth Heritage Group’s technical team of qualified, experienced professionals is capable of performing all types of archaeological investigations.


Literature Searches

Cultural resources investigations often begin with documentary research designed to identify areas where archaeological sites have or may be found. By reconstructing historical development, Commonwealth Heritage Group provides clients with a detailed land use record that is used to assess archaeological potential. Commonwealth Heritage Group’s land use histories have also served as the basis for hazardous site assessments.


Field Survey

The first field task in most archaeological projects is a controlled survey designed to locate archaeological sites. Relying on their expertise in anthropological, geographical, historical, and geophysical survey methods, Commonwealth Heritage Group’s field teams regularly complete successful archaeological surveys.


Geotechnology Services

Commonwealth Heritage Group provides a wide range of geotechnology services. Our professional staff includes geoarchaeological, geophysical, and geospatial specialists with expertise in geophysical prospecting and GIS-based predictive modeling for archaeological sensitivity, view shed analysis, and cultural resource database development. The capability to integrate geotechnology services into cultural resource projects results in a unified approach to illuminate archaeological data, enhance and support interpretations, and provide an additional foundation for understanding the historical and archaeological record.

Site Evaluation

Some archaeological sites require testing beyond survey. Our management and technical teams work together to design and implement excavations that maximize the recovery of field data. Analysis of field data and artifacts is geared to provide a conclusive assessment of significance and integrity for National Register of Historic Places eligibility determinations.


Data Recovery

Periodically, historically significant sites require excavation and analysis to mitigate project impacts. Commonwealth Heritage Group’s archaeologists are equipped to handle the technical and practical challenges encountered during data recovery projects. Clients receive the full range of data recovery services, including professional project design, intensive-level research, exacting field techniques, and technical reports and documents. We also design brochures, displays, and programs to meet project needs for public involvement and education.


Archaeological Collections Management Services

Commonwealth Heritage Group’s laboratory personnel have extensive experience in processing artifact collections and samples recovered from field investigations. Artifacts are catalogued in a custom-designed database, and inventories are prepared in accordance with state curation guidelines or the National Park Service’s Collections Management System (ICMS). Commonwealth features laboratory facilities that are fully equipped with computers, sinks, moveable drying racks, flammable and chemical storage cabinets, and refrigeration units for short-term storage of waterlogged specimens. We provide secure storage of project artifacts, from initial receipt to final repository. Our services also include exhibit design and fabrication.


Site Impact and Threat Assessments

Once archaeological sites are located, clients and review agencies need to know the type and extent of potential project impacts. Commonwealth Heritage Group routinely assesses project impacts to aid in planning and for use in environmental documents.
