The result of a productive collaboration with Peter Walker and Partners for use in their award winning Jamison Square, the aptly named Jamison design has been adopted by the design community as the new standard for a high quality, modern, pedestrian friendly trench grate.
Its clean modern rectilinear design of 1/4" openings offset by 3/8" bars seems simple, but belies the deep technical expertise needed to successfully cast this product.
Notable installations include University of Stanford School of Business, Dallas Performing Art Center, York Street in Toronto and many, many others.
