Daniel Falconer, American Concrete Institute's (ACI) managing director of engineering, has passed away at the age of 59 after a 16-month battle with colon cancer.

“Much can be said about Dan’s contribution and dedication to ACI, but I think it is best epitomized by his devotion to ACI during his battle with cancer,” said Ron Burg, ACI's executive vice president. “Dan’s last day in his office was June 17, just two weeks before he entered hospice. In spite of undergoing extensive and often exhausting chemotherapy, Dan continued to be a vital and contributing member of the ACI staff sharing his engineering insight, guidance, wisdom and good humor with both staff and members. He will be greatly missed.”

Falconer joined the ACI staff as managing director of engineering in 1998, providing support as secretary for the technical activities committee (TAC) and the standards board.

Falconer also served as staff liaison to ACI committee 318, structural concrete building code; subcommittee 318-SC, 318 steering committee; TAC design standards committee and TAC awards task group, and as a member of standing board committees on ETC product development and ACI board committee chairs. He represented ACI’s interests within the code, standards and specifications writing activities of numerous concrete-related groups. Falconer was named a Fellow of ACI in 2002.

“Dan had an incredible gift of taking a controversial technical issue and breaking it down into practical elements that would develop consensus,” said Randall Poston, past chair of ACI committee 318. “This came from his years of practicing structural engineering before joining ACI. He knew with continued resolve and steadfast guidance, committee members would eventually come together and ‘do the right thing.’ In large measure, the reorganization of the ACI 318-14 Structural Concrete Building Code was Dan’s vision of simplifying the use of the code for practitioners.”

Prior to ACI, Falconer held several engineering and marketing positions with VSL Corp. Before that, he was project engineer for Skidmore, Owings and Merrill in Washington, D.C.

Memorial contributions may be made in his name to Our Savior Lutheran Church, 13667 Highland Rd, Hartland, MI 48353.
