PAPER AWARDS

ACI Construction Award

ACI Design Award

Chester Paul Siess Award for Excellence in Structural Research

Wason Medal for Materials Research

Wason Medal for Most Meritorious Paper

ACI awards are granted by the Board of Direction on the recommendation of an Awards Committee. The designated recipients of the awards are invited to attend The ACI Concrete Convention and Exposition in the spring to receive the awards.

ACI Construction Award

Founded in 1944 by the Institute, the ACI Construction Award is intended to enrich the literature in construction practices and to honor the workers whose resourcefulness produces a completed structure from drawings and specifications. It may be awarded annually, but not necessarily in each year, to the author or coauthors of any paper of outstanding merit on concrete construction practice published by ACI. The award is presented as a plaque.

ACI Design Award

This award recognizes advanced concepts and techniques applied to a specific design project. Awards are given to the author or coauthors of the paper and to the engineer or engineering firm responsible for the design. Peer review is not required, and the award may be given annually, but not necessarily.

From 1997-2000, the award was named the Structural Engineering Award and was given for advanced concepts and techniques related to structural engineering. Up until 1997, the award was named the Maurice P. van Buren Structural Engineering Award and was given for a completed outstanding concrete building project incorporating advanced structural design concepts, advanced structural design techniques, or both, described in a paper published by the Institute. Recipients are awarded a plaque.

Chester Paul Siess Award for Excellence in Structural Research

The Chester Paul Siess Award for Excellence in Structural Research is given to the author or authors of a peer-reviewed paper published by the Institute that describes a notable achievement in experimental or analytical research that advances the theory or practice of structural engineering and, most importantly, recommends how the research can be applied to design. The award need not be presented each year.

Prior to 2004, this award was named the ACI Structural Research Award and before 1991, this award was named the Raymond C. Reese Structural Research Award. Through 1997, the award was given for a paper published by the Institute describing a notable achievement in research related to structural engineering and indicating how the research could be used. The award is a plaque.

Wason Medal for Materials Research

The Wason Medal for Materials Research was founded in 1917 by Leonard C. Wason, Past President of ACI. It may be bestowed annually, but not necessarily each year, on a member or members of the Institute reporting, in a peer-reviewed paper published by the Institute, original research work on concrete materials and their use, or a discovery that advances the state of knowledge of materials used in the construction industry. Prior to 1971, the medal mounted on a plaque was awarded to research papers dealing with any phase of Institute interests.
