Geotechnical & Engineering Services for Northern Kentucky.

Subsurface investigations, soil borings, foundation design recommendations, and geotechnical reports. Northern Kentucky's karst limestone geology — with its potential for subsurface voids, sinkholes, and unpredictable bedrock depth — demands a level of geotechnical rigor that separates experienced local firms from generalists. Our engineers have characterized the subsurface across Boone, Kenton, Campbell, Grant, Pendleton, and Gallatin Counties for decades. These conditions are not surprises to us.

CVG Airport & Aviation Infrastructure

Cincinnati/Northern Kentucky International Airport is the third-busiest cargo airport in North America and home to DHL's global super hub — and the $575 million Elevate CVG terminal modernization is the most significant infrastructure investment the airport has seen in a generation. Aviation infrastructure demands an uncompromising standard of geotechnical investigation, compaction testing, and special inspection that most CMT firms aren't equipped to deliver at scale. Alt & Witzig's proximity and depth of staff make us the natural choice for CVG-adjacent development.

Logistics & Industrial — Boone County

Amazon's $1.5 billion Air Hub at CVG — its largest global field operations campus — is just one marker of Northern Kentucky's emergence as a premier logistics destination. The I-71/75 corridor through Boone County, the industrial parks surrounding CVG, and the continuing expansion of last-mile and fulfillment infrastructure are generating sustained demand for geotechnical investigation and construction testing on large-footprint sites. Our Hebron office is embedded in this corridor.

Healthcare & Institutional Construction

St. Elizabeth Healthcare's $65–85 million Florence campus expansion, the $105 million NKU Health Innovation Center in Highland Heights, and the University of Kentucky's partnership with NKU and St. Elizabeth to establish a regional medical school campus represent a sustained wave of healthcare and institutional capital construction in Northern Kentucky. These projects demand the precision engineering, strict inspection protocols, and reporting discipline that Alt & Witzig has built its reputation on across the Ohio River.

Florence & Boone County Commercial

Florence remains Northern Kentucky's commercial center of gravity, with ongoing retail, mixed-use, and office development along the US-42 and Dixie Highway corridors. The Florence Mall redevelopment opportunity — with anchor vacancies creating significant adaptive reuse and new-build potential — represents the kind of complex, phased commercial project that requires environmental due diligence, geotechnical investigation, and construction testing managed as a single, coordinated program. The Kroger redevelopment at Cold Spring (131,000 sqft) is a model for the scale of commercial activity our team serves.

Covington & Kenton County Urban Development

Covington's continued reinvestment — driven by its proximity to downtown Cincinnati, improving walkability, and a deepening residential market — has generated demand for geotechnical and environmental services on infill and adaptive reuse sites where subsurface conditions are anything but straightforward. Kenton County's ongoing commercial and infrastructure development along the I-75 corridor adds to a steady pipeline that our team is already actively serving.

Campbell County & The Ohio River Corridor

Newport, Fort Thomas, Highland Heights, and Cold Spring represent a growing, high-value residential and commercial market on the eastern edge of the Northern Kentucky core. Campbell County's proximity to Cincinnati, its strong school systems, and its supply of developable hillside terrain make it a consistent source of new construction activity — but the Ohio River bluffs, karst geology, and variable bedrock depth in this county demand geotechnical experience that goes beyond standard practice. This is where our local knowledge earns its keep.
