ACI conducts due diligence reviews, reconnaissance-level studies, and Cultural Resource Assessment Surveys (Phase I, II, or III excavations). Projects are tailored to meet the client’s needs and agency requirements. We have completed individual projects ranging from 0.5 acres to over 75,000 acres, including projects that cross city, county, and state boundaries.


Over the past three decades, ACI has worked with federal, state, and local government agencies including the following:

  • Federal Aviation Administration
  • United States Coast Guard
  • National Aeronautics and Space Administration
  • National Park Service
  • United States Forest Service
  • United States Army Corp of Engineers
  • Federal Highway Administration
  • Florida Department of Transportation
  • Florida Division of Historical Resources
  • Sarasota County Parks and Recreation
  • City of Orlando
  • City of Tallahassee
  • City of Fort Myers



ACI frequently works with the USCG to review and assess the locations selected for the placement of infrastructure across and near waterways. Once a location is selected, ACI is often the firm chosen to complete the Cultural Resource Assessment Survey (CRAS) for the final location. The CRAS for the Fort Hamer Bridge was one such project, in which ACI initially evaluated the selected location for the bridge and then partnered with the USCG to address concerns raised during the tribal consultation process through the documentation of the history of Fort Hamer, and the Seminole Indian deportation during the Second Seminole War.

"Marion I would like to thank you and ACI for the wonderful work you have done during the Section 106 consultation process and for all the information that you provided to SHPO. Job well done!" – E.S., US Coast Guard Seventh District



We currently have a three-year contract with the U.S. Army Corps of Engineers, Little Rock District to conduct an archaeological survey of their managed lands in Arkansas and Missouri. ACI has fielded multiple crews at a time and they have covered over 3,300 acres and have excavated over 10,500 shovel tests to date. This work has resulted in the recording of 45 new archaeological sites, the updating of six previously recorded sites, and the discovery of numerous isolated finds.

"Knocked it out of the park; I agree with all of your recommendations." – A.W., District Archaeologist and Tribal Liaison US Army Corps of Engineers, Little Rock District

"Contractors quality is/was considered very good. Portions of the work exceeded expectations. Contractor completes work on schedule, sometimes ahead of schedule."

ACI has provided CRM services to NASA’s John F. Kennedy Space Center beginning in 1990. ACI developed a KSC-wide archaeological site location predictive model, covering more than 100,000 acres. All sites were documented and evaluated for National Register of Historic Places eligibility. ACI’s baseline maps are now part of the KSC Geographic Information System (GIS) database. ACI also developed a historic context for KSC, from the time of first European contact to the Space Age; formulated a predictive model for the location of historic archaeological sites and performed limited reconnaissance-level field survey to “ground-truth” the model.

We also prepared KSC’s original and updated Cultural Resource Management Plan (KSC-PLN-1733) and performed KSC-wide historic properties surveys in the context of both the Apollo Program and the Space Shuttle Program. Coordinating with NASA, ACI has assisted in the drafting of agreement documents addressing both archaeological site management and the treatment of historic properties and documentation packages in accordance to the National Park Service’s Historic American Building Survey/Historic American Engineering Record (HABS/HAER) standards. Finally, ACI prepared a National Historic Landmark nomination for the space shuttle orbiter Discovery.

These projects led to ACI collaborating with NASA to document the shutdown of the space shuttle program across the United States.  As a result of these efforts, ACI gained national recognition as a recipient of the U.S. Small Business Administration’s Award of Excellence, as well as a Blue Marble Award for the NASA Environmental Quality Group Award. Most recently, ACI was awarded by the KSC Environmental & Energy Program “for outstanding support to KSC’s Historic Recordation Mitigation Measure Process under the National Historic Preservation Act.” 

"I must say that I am very impressed. NASA’s consultants did an exhaustive job of research on the NASA-owned facilities at Santa Susana and were thoughtful in their eligibility determinations.... I very much hope that you have shared this report with your colleagues at Boeing and DOE, as I would love to see something of similar quality produced for evaluations of their facilities."

ACI has continuing service contracts with all FDOT Districts and the Turnpike Authority and has worked with prime engineering companies on numerous contracts to: conduct shovel testing along roadways, perform pond assessments, undertake historical structure surveys, and provide alternative corridor assessments.

"ACI’s ability to guide and work with an outstanding quality which has significantly contributed to their successful relationship with the FDOT...ACI has proven to be an asset to the Florida Department of Transportation’s Central Environmental Management Office." -- G.B., Administrator, FDOT

Your revision of the Department’s Cultural Resource Management Handbook ... ready for use on the Internet, is simply superb... The Handbook has exceeded the Department’s expectations in every respect." --C.I., Former Statewide Environmental Manager, FDOT



ACI has carried out cultural resource inventories, surveys, and monitoring in support of energy projects in various sectors including;
Solar and Wind, Exploration, Extraction, Generation, Transmission

For example, ACI has worked with oil exploration firms and the National Park Service to develop predictive models for archaeological sites in south Florida. For one such project,  ACI developed a predictive model and then conducted a cultural resource assessment survey of approximately 77,440 acres, shovel testing in 231 zones of archaeological potential (ZAPs) and conducting supplemental testing of low probability areas throughout the study area.

"From the time of my initial contact… to meeting your archaeology professionals… everyone involved handled our project with great speed and attention, it made me feel like our project was the most important project being worked on by ACI…. thank you for your immediate attention and very timely completion of the survey. I look forward to working with our company again."
