Built to significantly increase hospitality and conference space, this major hotel expansion added five floors of subterranean parking, three levels of ballrooms, auditoriums, sloped meeting rooms and a conference center, and 18 stories of hotel rooms. Project scope also included a dramatic lobby renovation and kitchen upgrade.

A Grand Stair is the hotel centerpiece, extending 20 feet in height and wrapping around two 35-foot tall columns. It provides a dramatic access between the hotel’s main lobby, Grand Ballroom, and the Wintergarden of adjacent Bellevue Place. Constructed of 62 tons of steel, the Grand Stair features Amber stone quarried from Spain at the treads and landings. A stainless steel and glass handrail boasts beautiful African Black Mahogany banisters.

Benefits of BIM

3D modelling efforts for structural steel and MEP systems proved beneficial for designers and subcontractors as the owner finalized or added design elements later in the schedule.


  1. Incorporating custom light fixtures with extensive structure support requirements
  2. Installing the grand stair which was “let in” to the existing Wintergarden
  3. Incorporating the Hyatt kitchen addition, which was designed after the project started.

During my visit, the hotel was surrounded by major construction activity, but it never impacted the quality of my stay. The contractor and hotel did a great job in maintaining high standards for guests amidst the construction.
