Marnell corrao associates have been designing and building resorts in las vegas for many years.  After building so many successful resorts they decided the next step meant designing and building their own resort unlike any other.

The m resort creates an awe inspiring campus that provides breath taking views of the valley as well as the las vegas Strip.  this building utilizes non-reflective floor to ceiling glass to take advantage of this view.  An open air environment is coupled with a beautiful canyon water fall feature to set apart the m resort from other las vegas resorts.

The building incorporates a casino, conference areas, health spas and salon, restaurants, bars, retail outlets, a generous amount of pool area, an entertainment venue and a large movie theatre.  All of these amenities are coupled with rooms and suites to accommodate most desires while remaining on the m resort campus. 

The casino, spa, conference area, retail, and other community items are on the lower few floors with the residential areas being on the upper floors.  The residential tower is wrapped in the above mentioned glass, being topped off with loft suites on the top floor, creating rooms with 270 degree views of the las vegas landscape.

historical requirements
building envelope

The upper portion of the building is comprised mainly of a glass panel system that combines to create the floor to ceiling picture windows.  At the base of the campus the walls are made of concrete panels wrapped in various decorative materials.  A built op roof was chosen to cap off the building. 


building statistics II


The low rise commercial section of the building is served by air handling units and make up air units.  Some of the spaces such as the casino floors are served with 100 percent outdoor air while other areas have some recirculation.  The high rise guest tower utilizes vertical stack fan coil units that are connected to integrated wall mullions which supply outdoor air.  Each room has its own unit which uses constant volume exhaust in the bathrooms to draw in the outdoor air.   The buildings utilities are housed in a central utility plant (CUP).  This allows services to be combined and thus become more efficient for the overall building.  The CUP includes 3900 tons of cooling and 46,800 MBH of heating with large expansion spaces available.  Heat exchangers are used to heat the heating hot water, kitchen hot water, and pool heaters. 




Electrical service enters the building at 12470 volts and it goes into a substation where it passes through a redundant switch.  It is them fed to the various electrical rooms where it is broken down into 277v, 120v, and other voltages based on equipment and power needs in the subsequent spaces.  The lighting system uses a variety of fixtures based on the space usage, however fluorescent fixtures are typical.  The system also includes two 2000kW/2500kVA emergency generators for life safety backup. 



The first floor of the low rise portion of the building uses cast in place concrete.  However the second floor of the same part of the building incorporates structural steel with spray on fire proofing.  The tower is cast in place concrete columns along with cast in place post tensioned concrete floor slabs measuring four inches thick.  The columns are set upon large spread footings throughout the entire building.


The guest tower is served by nine elevators, three of which are service elevators, along with stairwells.  The low rise section uses multiple elevators throughout each of the different space types as required. 


fire and life safety



The M Resort uses a sprinkler system throughout the majority of each section of the building.  Each exit stairwell is pressurized by a dedicated supply fan connected to emergency power.  The low rise spa and casino levels have smoke control systems that use either the supply fan or exhaust fan of the air handling unit serving the various areas with smoke control based on pressurization and exhaust requirements.  The guest tower corridors have supply and exhaust air grilles at each floor with fire smoke dampers to control airflow.
