This development consists of a new state of the art three storey head office, warehouse and distribution facility which includes a fully equipped fleet maintenance repair garage, a welding & maintenance facility and dedicated flammable liquid storage and paint-mixing rooms. The 3-storey office building 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 344,450sq.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.

This building won the Tilt-Up Achievement Award in 2022.

The Krahn Group was hired by Clutch Contracting to design this new multi- tenant concrete tilt-up industrial building on the corner of Hume Road and Brown Street in the popular Tilbury Industrial area of Delta, BC. This building features 7 grade loading doors, 24’ clear ceiling height, and LED lighting.

This development consists of a 203,175 sq.ft. concrete tilt-up multi dock loading warehouse/distribution center in the Tilbury industry park in Delta, BC, Canada. Tilt wall panels to the exterior of the building in conjunction with two internal brace lines provide the lateral support system. The gravity system is provided by the tilt wall panels to the perimeter of the building with internal structural steel framing consisting of beams and columns (supported off reinforced concrete foundations) providing support to the open web steel joists and metal roof decking. The ground floor consists of an 8” thick slab on grade. During construction a 50 ft. wide section of the perimeter floor slab was placed as the casting bed for the tilt wall panels. The remainder of the floor slab was placed at the end of the project after the underground services were completed and the building was fully watertight. This allowed for the easy addition of the trench and catch basins to the floor slab which were required by the single tenant user who was not identified until well into the project build. The tilt wall panels to the front elevation of the building consist of spandrel panel legs at the locations of the window openings to allow for the continuation of the spandrel glazing system as required for the architectural design of the building. The erection of the tilt wall panels was carried out in three separate lifts which allowed for a third of the building to be erected, structural steel and metal decking installed up to the internal brace lines allowing for the tilt wall braces to be removed and used for the next phase of the tilt.

The Krahn Group was hired by Spire Construction to design this two-storey concrete tilt-up strata warehouse building on 32nd Avenue in Surrey, BC.
