New Library Facts
An $84 million bond was approved by Salt Lake City voters in November 1998. Funding included the demolition of existing court and jail buildings; expansion and upgrade of the power plant serving the existing library, new Main Library, and City Hall; a Civic Plaza; a 600-stall underground parking structure; and expansion of the Sprague and Anderson-Foothill branch libraries.

The new Main Library building, furnishings, landscape, and plaza cost $65 million. The parking garage cost $15 million.
Groundbreaking for the new Main Library was in October 2000. The grand opening for the project was February 8, 2003.
240,000 square feet
A collection of more than 500,000 books, videos, DVDS, CDs, and books-on-tape.
8O,OOO new materials collected over the past three years.
163 computer stations with Internet access.
Three self-checkout machines.
Auditorium seats 300.
Number of visitors to libraries in the system expected to double; there are currently more than 1,000,000 visitors a year.
Library meeting rooms are available for use by the public at no charge, under the guidelines for room usage. Call (801) 524-8200 to make arrangements.
600-stall underground parking (parking stalls to be divided between the public, library staff, and city employees). Public parking is free for the first half hour and $1.50 per hour thereafter. East-West TRAX station on 400 South; UTA bus routes on 200 East.
Bicycle parking (near entrances and in the parking garage).
The current Main Library will be occupied by Global Artways, Center for Documentary Arts, and the Utah Science Center.
The Leonardo will bring together some of the area's most exciting arts, culture, and science experiences.
Construction Facts
Salt Lake City's Main Library project is one of the biggest construction jobs in the state over the past two years, bolstering Utah's construction economy following the construction boom that preceded the Olympics. Truly a local project, the new Main Library was constructed with Utah labor (95 percent) and materials (80 percent). During the construction, more than 2,000 workers contributed their skills to the project.
There are 44,960 cubic yards of concrete in the library building and parking structure. This is enough concrete to pour a sidewalk from Salt Lake City to Pocatello, Idaho.
In order to achieve an open atmosphere in the library, the architects eliminated most shear walls and interior bracing that would normally be used for structural and seismic support. Concrete beams and columns transfer the loads and the shear that the walls and bracing would normally accommodate. The concrete comprising these beams and columns is almost three times as strong as normal concrete.
There is 176,368 square feet of glass in the building, counting the curtain wall, interior glazing, glass windows, skylights, glass doors, and glass handrail (made with almost a half mile of glass).
The project has more than thirteen miles of plumbing piping.
with 320 miles (1,685,496 linear feet) of electrical and communications wire in the library, there is enough wire to go from the new Main Library to St. George, Utah.
Special finishes in the new library have come from all around the world, chosen for their cost and quality. The precast concrete that clads the building was manufactured in Mexico City, Mexico, and trucked over 2,000 miles. The concrete's rich color was achieved using natural sands and aggregate. Natural limestone pavers quarried from Israel constitute the plaza and the floor of the Urban Room. The rift-cut beech wood for cabinets and trim came from Eastern Europe. Som( ~chairs and the revolving front door came frorii Germany, the granite countertops from Persia, and some furniture from England, Italy, and Denmark. The fireplace trim marble is from China; the curved glass end panels of the bookshelves from Spain. Canada provided the glass elevators and several of the trees found in the plaza garden and around the library; the glass skylight near the walkable wall is from Austria.
Thousands of hours were spent in engineering and layout to achieve the lean of the crescent wall. The wall leans as much as 20 degrees out of plumb at the center of the wall, and goes back 90 degrees plumb at the end of the wall. To achieve this tilt, every piece of precast and steel in the wall is different.
The curtain wall of the lens on the south side of the project is a combination of glass, tube steel, and post-tensioned cable trusses. The cable trusses eliminate two-thirds of the steel's weight in the curtain wall, making the wall appear lighter.
The skylight over the Urban Room is approximately 20,000 square feet. It curves in two directions and slopes - a shape that required each piece of glass to be different.
When the Metropolitan Hall of Justice was demolished, the tower was pulled down less than 20 feet away from a live electrical service that fed the library, the City-County Building, and two city blocks. On the block, 156,742 cubic yards of earth was excavated.
There are 1,936,000 lbs. of steel in the building project.
The lens curtain wall cable trusses are tensioned to 100,000 lbs.
There are no ceilings in the vast majority of the library, so all of the plumbing, the electrical work, and the HVAC system are in an access floor
The primary source for cooling the library is evaporative water cooling, less expensive and more desirable ecologically than refrigerayed air.
The bridges leading from the library to the administrative area and the crescent wall are loose at one end and slide on a Teflon plate. This allows the bridge to move and resist collapse in the event of an earthquake.
The boiler plant from the original Metropolitan Hall of Justice project was saved and retrofitted during the project.
In order to minimize weight on the structure, yet allow planting, structural Styrofoam and a lightweight soil mix were used on the roof garden and parking structure,
The rooftop garden is planted with flowering ornamental trees, grasses, perennials, and flowering bulbs. These include Washington Hawthorn trees, Japanese silver grass, Little Bunny fountain grass, Elijah Blue fescue grass, Catlin's Giant carpet bugle, red-flowering thyme, Happy Returns daylily, and a mix of crocus, daffodils, and tulips for spring flowering.
