Old Flagship Department Store Becomes New Anchor for Downtown

Excerpt from article featured in the St. Louis Construction News and Review

The old Stix, Baer and Fuller department store building on Washington Avenue in downtown St. Louis is big.  It is big enough to hold three Walmart Supercenters, four new Nordstrom stores or five new Macy's stores.  With 620,000-square-feet of floor space, "it is too big for just one thing," said Andrew Smith, vice president at Trivers Associates.

So, the big challenge was finding the right uses that in combination could work together in the building - logistically, architecturally, and financially.  A project team that included developer Spinnaker Saint Louis, architect Trivers Associates, and general contractor BSI Constructors solved the challenge.

Riverlands Sanctuary Grand Opening

Riverlands Sanctuary Orientation Center in West Alton, Missouri had its ribbon cutting ceremony on October 14, 2011.  At the ceremony, a rehabilitated hawk was released by the Corps of Engineers.  A public opening was held on October 15.

Like a rest stop along an interstate highway, this 3,700 acre migratory bird sanctuary is nestled along the associated migratory patterns for 150 species of North American Birds at the confluence of the Missouri and Mississippi Rivers.  With the existing facility unable to handle the hundreds of human visitors that flock to the grounds, the Audubon Society and US Army Corps of Engineers engaged Trivers to design a new 4,200 square foot orientation center that affords additional exhibit space and expansive views of the Mississippi River.

The use of sensitive massing adjacent to the existing facility, along with the common materials integrated creatively, produces a new dynamic architectural entry and presence.  Designed to meld with the Corps educational program, the building integrates the architecture as exhibits.  The roof collects rainwater into cisterns that feed a wetlands exhibit pond directly adjacent to an outdoor classroom.  The floor has an inlaid migratory pathway map, creating a large scale exhibit.  When optimal environmental conditions (humidity and temperature) are present, an indicator light alerts the owner to deactivate the mechanical system and open windows for passive cooling.

Envelope and system technologies were designed to achieve a LEED® Silver level.  Glazing selection was coordinated with the mechanical engineer, reducing the energy use by 40% over the baseline model.  Energy savings are further achieved by automatic light level reduction through both occupancy and day-lighting sensors.  The building’s maximum lighting load is 0.8w/sf, allowing for lower long-term operational cost while providing a dynamic viewing and educational space for bird enthusiasts.

This design-build project was completed with The Clement Group and Volk Construction Company.  The design team included KJWW Engineering Consultants and Juneau Associates.  For more information on the project, contact Joe Brinkmann, AIA, LEED® AP at
