SKYSCRAPPER - 630 Ft.
YEAR BUILT – 1971 to 1974
50 STORY BUILDING
CONSISTS OF OFFICE – 1,557 & RETAIL – 20
DISTINCTIVE FEAUTURE:
CURVED TOWER WALLTHAT ARE SET BACK TO PROVIDE AN ATTRACTIVE AND ACCESIBLE SPACE
THE WALL IS MADE OFTINTED GLASS WINDOW AND WHITE TRAVERTINE LIMESTONE – STONE PANELCLADDING CONNECTION
SIBLING OF SOLOW BUILDING
FAÇADE - DESIGNED BY GORDON BUNSHAF
W.R. GRACE BUILDING
TRAVERTINE, A FORM OF LIMESTONE, IS USED FOR THE GRID PATTERN THAT COVERS THE SPACE BETWEEN WINDOWS IN THE GRACE BUILDING
TRAVERTINE IS A TERRESTIAL SEDIMENTARY ROCK. COMMONLY USED FOR FAÇADE, WALL CLADDING, BACKSPLASH AND FLOORING.
THE USE OF TRAVERTINE MAKES THE GRACE BUILDING APPEAR MORE BRIGHTER THAN ITS SURROUNDING AND THE WHITE COLOR CONTRAST THE DARK WINDOWS

AIR BARRIER SEALANTS, RAIN PENETRATION AND MOISTURE CONTROL
STONE VENEER/PANELS ARE STRONG AND DURABLE BUT THEIR WEAK POINT ARE THE JOINTS – IT NEEDS TO BE SEALED SO THAT WHEN WATER WONT SIP THROUGH OR THE WATER CANNOT DAMAGE IT
Use appropriate sealant for the environment in which it is expected to perform. Consider the environment that it will perform. Failure to consider these factors may result in adhesive failure, cohesive failure, craze cracking, hardening, disintegration, color changes, or other types of permanent failure.
Each project requires its own careful sealant consideration and application.

Precast Concrete Panels Air Barriers & SealantsAir Barriers & Sealants
Precast Concrete Panel - One-Stage Joints
A two-stage joint in a precast panel. The outer rain seal serves to control water leakage due to kinetic energy. Any rainwater that does penetrate the rain barrier drains to the outside, before it is able to reach the air seal.
Precast Concrete Panel - Two-Stage Joints
A one-stage joint in a precast panel wall system. In the so-called face seal approach, a single line of defense is employed against both rain penetration and air leakage.
Precast Concrete Panels Attachment SystemsAttachment Systems & & Fire SafetyFire Safety
Rebar and Grout
Used typically with slabs, reinforcing bars are spliced into slabs and grouted in place
Weld Plates
The most common method of attachment of precast members is by use of steel weld plates. Typically, the precast members have embedded plates that can be used as welding surfaces for loose connecting plates or angles.
Precast Concrete Panels Case Study:Case Study:Jubilee ChurchJubilee Church
The church has three curved walls resembling of a ship's sails, as it symbolizes "the ship in which the people of God sails."
The church has large glass surfaces that guarantee a generous flow of natural light, located both at the top and at the main and back facades.
In order to preserve the whiteness of the building, the company Italcementi developed a new cement containing titanium dioxide, called TX Millennium, which ensures the whiteness of the concrete, despite the pollution, rain and weather effects.
TX Millennium cement is formulated with photo-catalytic properties to deliver self-cleaning power. As a result, organic pollutants that settle on the surface of the concrete are decomposed into oxygen, water, and carbon dioxide.

The outer sail is composed of 78 segments, the intermediate of 104 and the inner, which reaches 26 meters, of 176 segments.
The builder had to invent a mechanism to manipulate the pieces and put them in place.

Precast Concrete Panels Case Study:Case Study:Beinecke Rare Book and Manuscript LibraryBeinecke Rare Book and Manuscript Library
Made of Vermont marble and granite, bronze and glass, the exterior gives the illusion that the building is completely solid when viewed from the outside.
Yale University’s Beinecke Rare Book and Manuscript Library is the largest building in the world dedicated to the containment and preservation of rare books, manuscripts, and documents.
Precast Concrete Panels Rain Penetration & Moisture ControlRain Penetration & Moisture Control
A rainscreen is the first line of defence against wind-driven rain, and as such is subjected to all forces leading to rain penetration through its openings and imperfections.
Precast Concrete Panels Air Barriers & SealantsAir Barriers & Sealants
Moisture ProtectionThe most common moisture protection system used with precast concrete wall systems is a barrier system incorporating an adequate joint seal. In some cases where additional moisture protection is needed, the application of a sealer or a concrete coating is also used. Sealers can be either clear or pigmented if used as an enhancement of the precast appearance. Film-forming coatings usually offer a higher level of performance but will have a significant impact on the appearance of the precast concrete unit.
The precast concrete panel should also be designed to provide the appropriate level of durability for the planned exposure. Durability can be improved by specifying minimum compressive strengths, maximum water to cement ratios, and an appropriate range of entrained air.
