County Prestress & Precast’s Elevator and Stair Shafts provide faster, safer, more precise alternatives to traditional cast-in-place construction. These structural precast concrete components are manufactured off site and delivered ready to be installed in a wide variety of building types.
Why Precast Elevator and Stair Shafts Are Used in Multi-Story Construction
Elevator and stair shafts are critical structural and life-safety components in multi-story buildings, providing vertical circulation, occupant egress, and often serving as key elements of a building's structural core. They also play an important role in construction sequencing by creating stable vertical access for workers, materials, and equipment early in the project.
Compared to traditional cast-in-place construction, precast concrete shaft systems help reduce field labor, minimize formwork and multiple concrete pours, and accelerate enclosure schedules. Manufactured off site in controlled plant environments and delivered ready for installation, precast shafts allow contractors to establish permanent vertical access sooner, improve jobsite safety, and maintain schedule certainty. In addition, PCI standards emphasize the importance of dimensional tolerances for coordinating structural systems, and precast manufacturing provides the consistent fit-up and precision required for efficient integration with adjoining building components.
Fire Safety, Code Compliance, and Long-Term Durability
Elevator and stair shafts often serve as part of a building's fire-resistance strategy. In multifamily housing, healthcare facilities, educational campuses, government buildings, and mixed-use developments, stair towers function as protected means of egress during emergency situations.
Because concrete is noncombustible, precast elevator and stair shafts can help support fire-rated construction requirements while providing long-term durability and resilience. Their inherent fire resistance makes them well suited for projects that require dependable life-safety performance and code-compliant vertical circulation systems.
Precast shafts are commonly utilized in:
For these applications, owners benefit from systems designed to perform throughout the building lifecycle while minimizing maintenance requirements.
Real-World Applications Across Multiple Markets
County Prestress & Precast has supplied precast solutions for numerous multifamily, mixed-use, affordable housing, student housing, and commercial developments throughout the Midwest.
Multifamily and Mixed-Use Housing
Projects such as Millhouse Flats, Bakery Flats Multifamily, The Retreat at Bayhaven, and Silvernail Apartments demonstrate the growing use of precast systems in multi-story residential developments where speed of construction, fire-resistance requirements, and predictable schedules are critical. These projects represent the types of developments where elevator and stair shaft systems can support early vertical access and faster building enclosure.
Affordable and Senior Housing
Projects such as RWD Burnsville Affordable Housing and McKenna Crossings illustrate the need for dependable, code-compliant vertical circulation systems in residential communities where occupant safety and schedule certainty are priorities.
Office and Mixed-Use Development
Developments like Gallery Bloomington highlight the continued demand for efficient core construction solutions that can support parking, amenities, retail, and residential occupancies within a single project. Precast shaft systems help maintain construction momentum by reducing reliance on labor-intensive cast-in-place operations.
Government and Civic Buildings
Projects such as Pleasant Prairie Village Hall demonstrate how public-sector facilities frequently require durable, long-lasting structural systems that provide reliable vertical access and support stringent construction requirements.
Benefits of NPCA-Certified Manufacturing
County Prestress & Precast manufactures elevator and stair shaft components in NPCA-certified facilities. The National Precast Concrete Association's certification program is recognized throughout North America and focuses on quality control, consistency, process monitoring, inspection, and production standards. The NPCA Quality Control Manual provides manufacturing requirements intended to help ensure consistent, high-quality precast products.
Off-site manufacturing offers several advantages:
NPCA notes that certification and quality-control programs provide confidence that products are being produced according to established industry standards and monitored through ongoing inspections.
How Precast Shafts Improve Construction Sequencing and Safety
One of the greatest advantages of precast elevator and stair shafts is the ability to establish permanent vertical access earlier in the construction process.
According to OSHA, falls continue to be the leading cause of death in construction, accounting for hundreds of fatalities annually. OSHA and NIOSH continue to promote planning, safe access systems, and fall prevention as essential jobsite safety priorities.
By reducing field-built formwork, vertical concrete pours, and repetitive work at elevation, precast shafts can help contractors minimize worker exposure to fall hazards. Earlier installation of permanent stair towers also improves worker movement throughout the structure and reduces reliance on temporary access systems.
For developers and general contractors facing labor shortages and compressed schedules, installing shafts earlier can improve:
In many applications, elevator and stair shafts become an early focal point of construction sequencing, creating a stable core from which the remainder of the structure can advance efficiently.
