The Crystals was designed to stand as the centerpiece of CityCenter’s retail and entertainment district along the Las Vegas Strip. It’s dramatic spiraling roof made up of 19 separate roofs overlapping each other elevates the project to a class of its own.
With 16,445 pieces of steel jutting out in every direction, The Crystals roof proved to be the biggest challenge of the project. It was made up of 13 planar roofs and 6 dramatically sloped arcade roofs. The arcade roofs were the most complex element. They posed a challenge for our team through various stages of the project, making it difficult to manage scheduling and budget demands.
Overcoming the challenges that came with building The Crystals began in the early pre construction phase. It took our design-assist team 12 months to devise an accurate 3D depiction of the structure. The roof had no right angles, nor did it follow a pattern or contain any repetitive placements of steel. Our team strategically planned ahead then worked every step backwards.
The plan was to first determine where the 80 major trusses would be placed. Then from there, we placed the pieces that the trusses would support. The Crystals roof required thousands of massive beams, 160 trusses and 69 pipe columns cutting through one another at extreme angles. Every piece of steel had to be carefully calculated in the planning stage to account for load capacity, fabrication and constructibility. There would be no room for error.
