The Hart on Main, located at 622 NE A Street, is a landmark mixed-use development on the north side of Bentonville's historic downtown square.

Developed by Blue Crane and Riverside and designed by Herzog & de Meuron with Page as Architect of Record, the project comprises 222 residential units, 90,000 sf of Class A office space, 30,000 sf of ground-level retail, and two levels of below-grade parking with approximately 400 stalls. Residential buildings are seven stories, and office portions are six stories, both within an 80-foot height limit. The development preserves key historic elements, including the Benton County Jail, listed on the National Register of Historic Places.

RDH is providing integrated building enclosure consulting services, combining Roofing & Waterproofing Consulting and Facade Engineering from Schematic Design through Construction. For the roofing and waterproofing scope, RDH is working in a design-assist capacity to develop assembly recommendations for all horizontal enclosure systems including below-grade waterproofing, slab-on-grade, podium slab, occupied terrace and pool waterproofing, CLT roof and balcony assemblies, garage ceilings, soffits, and traffic coatings, producing a comprehensive Building Enclosure Assembly Matrix, technical specifications, and construction-phase submittal and RFI support. For the facade engineering scope, RDH is developing design concepts from first principles and advising on system selection, thermal and solar performance, glazing and masonry materials, procurement strategy, and constructability. This includes preparing a Facade Basis of Design document, performance criteria, outline specifications, and CAD details for all vertical enclosure systems, including brick cladding, punched windows, storefronts, and canopies.

A key area of focus is the mass timber (CLT) portions of the residential building, where RDH is developing specialized strategies to protect the CLT structure at balcony and roof interfaces, a critical consideration given CLT’s sensitivity to moisture exposure.
