  • 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

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.

ACI also conducts desktop analysis and archaeological survey for a variety of energy projects from new and replacement utility lines to solar projects for Florida Power and Light. Survey strategy is refined to meet the project needs in coordination with guidance from the lead FPL archaeologist.

"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."

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!"

ACI recently completed a three-year contract with the U.S. Army Corps of Engineers, Little Rock District conducting an archaeological survey of their managed lands in Arkansas and Missouri. ACI fielded multiple crews at a time and they have covered over 6,000 acres and excavated almost 20,000 shovel tests. This work has resulted in the recording of 87 new archaeological sites, the updating of 18 previously recorded sites, and the discovery of numerous isolated finds. 

ACI has also partnered with numerous engineers and developers in completing surveys that meet US ACOE standards for permitting.

"Knocked it out of the park; I agree with all of your recommendations."

"This has been one of the smoothest contracts I've worked in years …  It was really good working with you all."

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 participated in the “Resilient Heritage in the Nation’s Oldest City” project for the City of St. Augustine. The project created an educational report and website focused on protecting the City’s historic structures and archaeological sites against flooding. Included in the report was a discussion on the prioritization of archaeological resources and a review of policy and codes which could incentivize the City’s resilience and help protect cultural resources. ACI provided input on all aspects of the project, which also included an economic analysis of past flood events and flood mitigation recommendations.

We conducted numerous excavations and monitoring projects within downtown St. Augustine on private, state, and University of Florida-managed properties. Prior to the expansion of the public restroom on St. George Street, ACI conducted extensive excavation for the University of Florida, we have monitored several construction projects such as utility line installations and landscape reconstructions, and conducted excavation and monitoring for the awarding-winning Colonial Quarter project.

"As Taylor Engineering’s project manager for this effort, I relied on Senior Project Archaeologist Christine Newman.  Chris provided timely guidance, leadership, and her essential perspective throughout the project.  On her own initiative, she assembled a volunteer stakeholder group of local archaeologists to guide our tasking. Adapting any structure to be more resilient to flooding is a challenging task, but historic properties   with   extensive   archaeological   resources   are   especially   sensitive.   I   appreciated   Chris’ perspective, as she often spoke up during project team meetings to give us critical inputs ensuring we would protect archaeological resources in addition to the chosen historic buildings."

Recent focus on Everglades Restoration and water distribution and storage projects in South Florida have given ACI an opportunity to further refine the South Florida predictive model. ACI utilizes the CERP model approved by the ACOE, including examination of historic aerial images, land use history, historic plat and military maps, LiDAR data, soil data, and topographic maps. Several large scale projects have been completed in recent years and have received U.S. Army Corps, State Historic Preservation Office, and Seminole Tribe of Florida approval. ACI is pleased to help clients navigate the requirements from various reviewing agencies and understand the archaeological and historical potential of their projects.
