This existing building had some structural challenges that came first and foremost in this overall core/shell rehabilitation project. Working with Robertson & Olson VIP client Killian Pacific, we gathered on the historic concrete slabs—literally standing in the boot prints of laborers from over a century ago—to begin project planning. We took an active role in the structural design of this project. When the #4 rebar and the limited available dead load of thick concrete clashed, we offered up design/build carbon fiber reinforced polymer (CFRP) services. When mechanical, electrical and plumbing combined, we needed 572 slab penetrations, worked in amongst 17 miles of PEX tubing for hydronic heating and cooling. This was no small task, but our team and partners breathed new structural life into a 100-year-old building. This successful LEED Platinum project earned us a Daily Journal of Commerce TopProjects award and was the first ever Energy Trust of Oregon High Performance Building. We are proud to have helped prove our client’s concept that market-rate office space can respect history sustainably.
