While at a prior firm, Ron Lee, P.E., led the full structural design for the entire Mansion development. The Mansion at MGM Grand opened discreetly in 1999, hosting coveted, high-rolling “whales” by invitation only. The 290,000-square foot Mansion showcases 29 private Garden Villas and Atrium Villas ranging from 2,400 square feet to 12,000 square feet, each with its own indoor pool.  The Mansion, now known as the most expensive hotel in the world, recently opened its immense bronze and crystal doors to discriminating clientele willing to spend $5,000 to $15,000 per night.

The structural system for the Atrium Villas consisted of concrete flat plate slabs and concrete shear walls founded on drilled pier foundations.  The flat slabs are post-tensioned in one direction and mild reinforced in the perpendicular direction.  The Atrium Villas feature a 240 ft by 240 ft clear spanning glass roof supported by curved and tapered trusses.  The framing system for the Garden Villas consists of welded bent steel roof beams and CMU walls founded on spread footings.
