Tilt-Up Achievement Award

The Krahn Group of Companies was thrilled to hear that Krahn Engineering Ltd. will be awarded a Tilt-Up Achievement Award (along with a shiny new plaque!) from the Tilt-Up Concrete Association for our structural engineering work on Lordco Auto Parts Head Office project.

In addition to furthering the awareness of the awesome potential and capabilities of tilt-up concrete construction, this award shows that Krahn Engineering is proving to be an authority in structural engineering design for the industry, something that we pride ourselves in. Krahn works directly with Tilt-Up manufacturers to ensure our engineers can provide the best service and design to our clients.

The TCA Tilt-Up Achievement Awards program was established to honor projects that use site-cast tilt-up concrete to introduce new building types, advance industry technology and provide unique solutions to building programs. The winning entries illustrate the variety, beauty, and flexibility of the tilt-up construction concept.

Read on to know more about this exciting project and the structural engineering accomplishments!

The 3-story office building with a combined approximate area of 46,000 sq. ft was constructed using a combination of structural steel moment frames and tilt wall panels (supported on reinforced concrete foundations) which provided both the gravity and lateral support systems to the office portion of the building. Open web steel joists and steel beams provided support to the metal deck at roof level. The floor structure at second and third floor was constructed using open web steel joists and steel beams supporting the composite metal deck and concrete floor slabs.

The height of the tilt wall panels to the office area were predominately 48ft tall rising up to 53ft at certain locations. A secondary steel frame, fixed back to the main structure was used to support the overhanging glazing, canopies and cladding systems employed to the front and the side of the building. The office component also included a full height atrium to accommodate the feature spiral stairs under the 540sq.ft skylight and a second-floor external patio.

The warehouse and distribution facility consists of a floor area totaling approximate 328-194 sq. ft. with a clear height of 32ft which was a requirement for the racking which consisted of both automated and manual multi-level picking modules.  Tilt wall panels to the exterior and interior of the building provide the lateral support system with the combination of tilt wall panels and structural steel frame on reinforced concrete foundations providing the gravity system supporting the open web steel joists and metal roof deck.

Due to the large footprint of the building and the racking layout requirement to the interior of the building the interior tilt wall panels did not run the entire length of the building. The roof finish was changed from a ballasted roof to a TPO roof to reduce the dead load and in turn the seismic load. Large drag struts were required to be designed to transfer the lateral forces from the roof beams into the internal tilt wall panels and between the tilt wall panels. Hold downs between the panel ends and foundation were also required at a number of the internal tilt wall locations.

We were eager to work alongside Conwest and Lordco Auto Parts on the development, and would like to extend our congratulations to them both, in addition to Craig Mitchell Architecture & Design (now CTA architecture + design) and Capo Construction for helping to bring this project to life.
