Building a Landmark: The Women-Led Team Behind North America's Largest ICF Project
As the demand for more resilient, energy-efficient, and sustainable multifamily housing continues to grow, innovative construction methods are reshaping the future of residential development. One project helping lead that transformation is Aspen at Greenleigh, a 335-unit luxury multifamily community currently under construction in Middle River, Maryland.
KLINE is proud to serve as the Engineer of Record (EOR) for this landmark project, which is expected to become the largest Insulated Concrete Form (ICF) project in North America. This milestone reflects both the growing adoption of ICF construction and the vision of the project team behind it.
Engineering North America's Largest ICF Project
Aspen at Greenleigh represents a significant advancement in the use of Insulated Concrete Form (ICF) construction for large-scale multifamily developments. The residential community consists of four interconnected seven-story residential structures built entirely using ICF construction, demonstrating the system’s scalability and performance advantages for modern residential design.
At the center of the development, a post-tensioned concrete parking structure utilizes PT beams and one-way PT slabs, providing an efficient and durable structural solution that complements the residential buildings. The system maximizes parking efficiency while delivering the long spans and durability required for a high-density multifamily community.
As Engineer of Record, KLINE provided the complete structural design for both the residential and parking components, integrating innovative structural systems to support the project’s long-term performance, resilience, and sustainability goals.
From Vision to Reality: Engineering Through Change
Delivering a project of this scale requires more than technical expertise; it demands adaptability.
Since the earliest stages of design, Aspen at Greenleigh has undergone multiple iterations as the project team evaluated structural systems, construction methods, efficiency opportunities, and long-term performance objectives. Throughout that process, KLINE worked closely with the ownership, development, and construction teams to refine the design and identify solutions that balanced constructability, cost, schedule, and performance.
The resulting design combines two structural systems tailored to the development’s unique requirements. The six-story residential buildings utilize Insulated Concrete Form (ICF) construction with Vescom floor joists, creating a durable, energy-efficient residential structure. At the center of the development, the five-level parking garage utilizes cast-in-place post-tensioned concrete beams and one-way PT slabs, providing the long spans, efficiency, and durability required for a modern parking facility.
This integrated approach reflects KLINE's experience delivering complex projects in which engineering solutions must evolve alongside project goals while maintaining a focus on quality, efficiency, and long-term performance.
Why ICF Matters
Insulated Concrete Form construction combines the strength and durability of reinforced concrete with continuous insulation, creating structures that deliver exceptional performance across a range of applications. Compared with conventional construction methods, ICF buildings can offer improved energy efficiency, enhanced acoustic separation, increased fire resistance, and superior resilience to severe weather and environmental exposure.
While ICF has long been recognized for these benefits, projects of this scale demonstrate that the technology is no longer limited to niche applications or low-rise construction. Aspen at Greenleigh highlights the growing role of ICF in large multifamily developments where long-term performance, occupant comfort, and sustainability are key priorities.
The Future of Multifamily Construction
The multifamily market continues to evolve. Developers are seeking greater energy efficiency, municipalities are demanding higher sustainability standards, and residents increasingly value comfort, resilience, and quality.
ICF construction addresses each of these challenges simultaneously.
Insulated concrete forms offer unmatched ease of use, exceptional strength, and long-lasting durability, making them an ideal choice for new construction projects.
Projects like Aspen at Greenleigh demonstrate that ICF is becoming an increasingly viable and attractive solution for large-scale multifamily developments where performance, durability, and long-term value matter most.
