Site Work and Buildings at Redtail Ridge Along U.S. 36
Cleared land is not empty land. When a former corporate campus has been demolished, what remains below grade is a mix of old foundations, buried utilities, compacted fill and drainage paths that no longer match the surface, and a builder has to find all of it before pricing a single new pad. We do that work on large mixed-use and employment sites, and we bring the same approach to the 389 acre Redtail Ridge development along U.S. 36.
Louisville City Council approved Redtail Ridge on a 5 to 1 vote reported August 28, 2024, with plans to relocate a hospital, build an industrial and medical research park and include more than 500,000 square feet of office space. A program like that is delivered in pieces: roads and utilities first, then pads, then buildings for different users on different timelines. We structure our construction management at risk work to match, with early site packages bid while later buildings are still being designed.
The land has a history that a careful builder reads closely. It was annexed into Louisville in 1978 as a 310 acre corporate campus, the owner who bought it in 2008 demolished the roughly 1.6 million square foot complex, and a 2021 plan was repealed by voters in 2022. The lesson for any owner or tenant is to treat approvals and site conditions as live questions until they are documented.
What a former campus leaves behind
Before design is final, we recommend a records review and a targeted investigation of the site: old foundation locations, abandoned utility lines, fill depths and any environmental conditions recorded in prior studies. These are items that do not show on a topographic survey and are expensive to discover during excavation. A round of test pits and borings costs far less than a single week of unplanned equipment time.
Where old foundations remain, the choice is between removal and reuse of the compacted soils around them, and the answer depends on the new building's loads. The trade partners for demolition remove and recycle concrete on site where specifications allow, and the geotechnical engineer confirms that compaction and moisture conditions meet the structural design. Recycling the material reduces trucking, which on a site this size is a meaningful part of the budget.
Roads, utilities and pads first
The first packages on a campus-scale site are mass grading, storm drainage, water and sewer, dry utilities and the internal roads. We perform mass grading in a way that balances cut and fill, controls erosion and leaves pads at the elevations the tenants' buildings need. Staging the grading by phase keeps disturbed areas small and reduces dust and stormwater violations.
Then come the vertical buildings. A research or medical building has heavy mechanical and electrical needs, while an office building has long floor plates and parking demands. We stage utility stubs and pad preparation so each user can move in at its own pace without disturbing neighbors who are already operating.
A site served by two roads
The Redtail Ridge site abuts U.S. 36 on the east and the Northwest Parkway on the south. The city's traffic study estimated 21,285 additional daily vehicle trips, with 75 percent to or from those two roads. For owners, that is a large number, and it means access design, turn lanes and signal timing will be among the most closely reviewed parts of any building permit on the site. We include road and signal improvements in our early budgets, along with the time it takes to get approvals from the road authority.
It also means that the U.S. 36 corridor is more than a location: it is a construction constraint. Heavy loads, steel deliveries and concrete trucks will share the corridor with commuters, so we plan haul routes, delivery windows and temporary traffic control well in advance.
Phasing a multi-user campus
A multi-year campus rarely moves in a straight line. Market conditions, tenant decisions and approvals shift. We build a phasing plan with decision gates: after each major package, the owner can proceed, slow or reorder the next one. We keep long-lead procurement flexible and avoid committing equipment until a tenant is firm.
Seasonality also matters at this elevation. Grading and utility work are best done in warm, dry months, while enclosure and interior work can run through winter. We schedule so that the building shells are weathertight before the cold sets in and the interior trades have heated space.
Offices, research space and medical use
The approved program mixes office buildings with an industrial and medical research park and a relocated hospital. Each calls for a different structure and a different approvals path. Hospital construction involves state licensing, infection control planning and complex mechanical systems, and we describe our approach in the healthcare hospital overview. Research and light-industrial buildings call for flexible floors, high ceilings and strong utility capacity.
Owners in the healthcare systems sector will find that early coordination with the design team and the authorities having jurisdiction saves months. We bring that coordination to the table, with a project manager assigned to that review from preconstruction onward.
Working with the owner and the town
Large mixed-use projects live and die on relationships with the municipality. We meet with city staff early, bring a clear scope and schedule, and keep a written record of commitments on both sides. If the project involves a development agreement or public infrastructure financing, we work with the owner's counsel to estimate construction cost accurately and to track it against the agreement.
Town staff and utility providers sit on the critical path of every phase, so we treat the municipality as a partner in the broader Louisville market and not as an approval stop at the end of design.

Questions Owners Ask
Is Redtail Ridge approved?
Louisville City Council approved the development on a 5 to 1 vote reported on August 28, 2024. Individual buildings still need site plans, permits and inspections, so each tenant should confirm current approvals with the city.
What does the traffic estimate mean for a builder?
The city study estimated 21,285 additional daily trips, with 75 percent using U.S. 36 or the Northwest Parkway. We expect road improvements and detailed access reviews, and we plan construction traffic to avoid peak commute periods.
What should we investigate on a former campus site?
Old foundations, abandoned utilities, fill depth, drainage paths and any environmental records. Pre-design investigation costs little compared with discovering these during excavation.
Can we start with just one building?
Yes, if the infrastructure that serves it is planned and the owner or developer agrees on cost sharing. We price the first building with its share of roads and utilities so that you can see the full cost.
Why does the project history matter to us?
A 2021 plan for the land was repealed by voters in 2022, and the current plan was approved in 2024. That record shows how closely the community follows development, so we advise owners to plan for public review.
