By Wally Ford\u00a0<\/span>\u00a0<\/span><\/p>\n

A revolutionary building method that can reduce commercial high-rise construction time by one-fourth or more is poised to become a game changer in the AEC industry.\u00a0<\/span>\u00a0<\/span><\/p>\n

The method, dubbed \u201c<\/span>SpeedCore<\/span>\u201d for obvious reasons, is a concrete-filled composite plate shear wall that can be used for constructing a building\u2019s core. As opposed to a traditional concrete<\/span>\u00a0<\/span>shear<\/span>\u00a0<\/span>wall,\u00a0<\/span>SpeedCore<\/span>\u00a0does not require internal reinforcing, as each section is sandwiched between two hot-rolled steel plates that provide permanent external reinforcing \u2013 which also eliminates the need for concrete forms that would be thrown away. One of the latest developments in the growing use of prefabrication, the panels are built in steel fabrication plants, shipped to the job site, and simply stacked and welded or bolted together. The result: substantially faster high-rise construction and less waste.<\/span>\u00a0<\/span><\/p>\n

I\u2019ve been watching the development of\u00a0<\/span>SpeedCore<\/span> ever since the idea was conceived several years ago and subsequently researched by Purdue University with partial funding from the American Institute of Steel Construction (AISC), which continues to promote the use of the method. <\/span><\/p>\n

As <\/span>reported by ENR magazine in 2020<\/a><\/strong>,<\/span>\u00a0testing has shown that\u00a0<\/span>SpeedCore<\/span>\u00a0needs no external fire proofing. This will result in additional savings in cost and time for future projects.\u00a0\u00a0<\/span>Still, the upfront cost of\u00a0<\/span>SpeedCore<\/span> will always be substantially more than traditional reinforced concrete cores. The return on investment, therefore, will only be realized in high-rise construction, where the time saved on every floor adds up \u2013 and the more floors you have, the more time you gain. Steel erection time on\u00a0<\/span>Rainier Square<\/strong> Tower<\/strong><\/span><\/a>\u00a0in Seattle, one of a handful of West Coast projects to use\u00a0<\/span>SpeedCore<\/span>, was cut nearly in half.\u00a0<\/span>\u00a0<\/span><\/p>\n

The existing\u00a0<\/span>SpeedCore<\/span>\u00a0projects are in highly seismic areas, where lighter, structural steel framing is required instead of heavier concrete in order to lessen lateral forces on the building. I predict that\u00a0<\/span>SpeedCore\u2019s<\/span>\u00a0spread initially will be primarily in commercial office building towers, which often<\/span>\u00a0<\/span>use structural steel framing even outside of seismic areas \u2013 where the savings in time and cost will be even further augmented by the ability to bolt the panels together instead of welding them \u2013 a more labor-intensive process that is required in seismic locations.\u00a0\u00a0\u00a0<\/span>\u00a0<\/span><\/p>\n

For\u00a0<\/span>SpeedCore<\/span>\u00a0to catch on in residential towers, however, the industry will need to find a way to speed up construction of the flat plate floor framing systems typical of that sector. Flat plate floor systems reduce floor heights and ceiling costs for residential towers, but the construction and curing of such cast-in-place concrete floors is time intensive. This causes the critical path to run through the pouring of the slabs around the core instead of the erection of the shear walls. That\u2019s what kept\u00a0<\/span>SpeedCore<\/span>\u00a0from being used on a high-rise residential project in Austin. We prepared schematic pricing documents for the project using a\u00a0<\/span>SpeedCore<\/span>\u00a0scheme, which were priced by a fabrication\/erection team. The cost analysis showed the method to be untenable.<\/span>\u00a0<\/span><\/p>\n

Would I propose\u00a0SpeedCore\u00a0for a project? In the right circumstances, yes. For example,<\/span>\u00a0<\/span>we recently designed a 38-story office building in downtown Denver using a traditional concrete core with steel framing wrapped around it.<\/span>\u00a0<\/span>Were we to design that building today, we\u00a0definitely would\u00a0propose using\u00a0SpeedCore.<\/span>\u00a0<\/span><\/p>\n
