See the Cupola Installation as it Happened

The classic design of this new state building that will serve the people of Nevada’s as its highest court is perfectly complemented by the cupola whose classic look recreates the dignity of famous buildings worldwide. The Prestige team is proud to have participated in building and delivering the dome. We’d like to share some of the images as it happened.

The Copper Dome Project Beginnings

The dome project began with building the underlying structure and cutting, shaping and installing the copper on the dome’s steel frame. The dome was designed and built so that it could be dismantled in sections for transport to the installation site.

As a final step in the construction process, the brilliant new copper was aged to give it the classic patina that beautifies copper domes and copper roofs atop structures around the world. The classic green Copper dome preparing the bottom of the copper cupolapatina was achieved with an acid mixture that accelerates the normal oxidation process that results in the changing coloration. Left to itself in the dry desert air, the dome would have turned a “dirty penny” brown patina, while the more attractive and recognized aged copper green patina, which needs moisture from the surrounding air to form, happens most quickly in coastal areas. With a little help from us, the dome was able to achieve that natural effect and present itself from the start in its most beautiful colors.

Copper Cupola’s Smooth Delivery to its new Home

Fully complete, the dome itself weighs about 7,200 lbs and is 14 ft tall with a diameter of 20 ft. The circumference is 63 ft, so transporting it across town was made easier by sectioning the large structure. The sections were loaded and transported from our facility in North Las Vegas to the downtown Las Vegas construction site of the now nearly complete Nevada State Supreme Court building.

Each quarter of the copper dome was separately hoisted by crane onto the lantern, or elevated section of the roof, which serves to raise up the decorative cupola and spire for better visibility from below.

The four sections of the cupola were then reconnected to reform the entire structure in its new home. Once the cupola was in place and secured, we were ready to install the decorative spire and statue of Lady Justice to cap off the beautiful structure. Using a crane and lift, we secured those finishing touches place.
