Grand River Institute houses a complete archaeological laboratory and library of regional cultural resource documents. It has computer capabilities for data processing and report preparation. The laboratory also serves as a temporary curation facility for ongoing and recent projects.

All studies are designed to maximize cultural information retrieval while minimizing the client’s time/cost factors. Field work can often start the day after the request is received, and reports are generated immediately following its completion. The only exception to this is inclement weather, as the permitting agencies have strict requirements regarding snow cover and ground visibility.
