Achieve Ultimate Efficiency and Safety with Precast Stair Shafts

Precast stairwell shafts are a purpose-built and efficient building access solution. Manufactured with the leading precast technology and materials, County Prestress & Precast’s concrete stair shafts are safer than traditional counterparts and turn buildings over to trades sooner than conventional alternatives allow. To maximize your budget and construction schedule, we also offer delivery and installation services.

Shorten Construction Schedules

Precast stair shafts up to five stories tall can be erected in a single day—much faster than the average construction time of three to four weeks for a similar shaft built with conventional methods. Since stair shaft construction is part of the critical path for any multi-story project, weather delays during shaft construction can lead to costly delays in the entire project. With precast shafts, erection can happen in a broad range of temperature and weather conditions, leading to fewer delays than with conventional methods.

Precast concrete requires less labor and fewer inspections than traditional methods, and off-site production means the shafts can be produced while the site is being prepared to minimize downtime.

In addition to precast stair shafts, County Prestress & Precast offers a full line of precast concrete construction products. When used together, these products can contribute to further construction efficiency:

Improve Safety During Construction and Occupancy

The use of precast stair shafts can help eliminate the need for dangerous temporary ladders and stairs and contribute to a safer jobsite.

Precast stair shafts allow immediate access to:

  • Stair installers and tradesmen
  • Inspectors
  • First responders
  • Fire suppression pipe stand

County Prestress & Precast’s Stair Shafts are produced in National Precast Concrete Association-certified (NPCA) facilities and achieve two-hour fire ratings. During production, our shafts undergo quality control testing ensuring that every component meets standards with measured and monitored outcomes.

Achieve Greater Dimensional Precision

County Prestress & Precast can manufacture shafts up to seven stories tall with or without precast caps. To ensure quality and consistency, our prefab concrete shafts are made in NPCA-certified manufacturing plants. We manufacture our shafts to your precise project requirements as well as all federal and local codes and regulations. Our state-of-the-art concrete forms ensure that our shafts are dimensionally precise, offering greater accuracy in the vertical plane than conventional shafts for seamless integration with other building components.

Precast Stair Shaft FAQs

What are precast stair shafts?

A precast concrete shaft is an efficient way to add a stairwell shaft to mid-rise structures. These prefabricated shafts are manufactured off-site and then transported to the project site for installation. Once in place, you can add precast concrete stairs or other means of passage between floors. Precast stair shafts are weather-resistant and fire-resistant, and they require minimal maintenance.

What kind of buildings are compatible with precast concrete stair shafts?

Precast concrete shafts are designed to accelerate the construction process for mid-rise wood framed, steel stud framed, and modular buildings. Precast shafts are an ideal solution for hotels, office buildings, military barracks, student housing, assisted and independent living facilities, apartment complexes, and multifamily construction.

How long does it take to erect a single precast shaft?

Our experienced team delivers and assembles the shafts with a telescoping boom manlift, eliminating the need for scaffolding. Stair shafts up to five stories tall can be erected in one day.

Can precast shafts be erected in winter conditions?

Precast stair shafts can be erected in many wintry conditions in the same amount of time as summer conditions.

Do precast shafts require temporary bracing?

No temporary bracing is required because the precast elements are monolithic boxes which can withstand construction wind loads due to the inherent weight and strength of the concrete mix and the permanent connections between each segment of the shaft.
