NEWS SCOPE READY MIXED rials and a required strength of 8,000 psi. Similar specifications were required for the columns and shear walls. Additionally, a special mix design was de- veloped for the elevated slabs to meet the specified light reflectance criteria. The project design team was able to add a thir- teenth floor due to the concrete's reduced floor-to-floor height, and the concrete structure eliminated the sunlight-blocking beams. The resulting mix designs lowered the CO2 footprint by 50 percent—a reduc- tion of 7.4 million pounds in CO2 emissions from embodied carbon. The decision to switch from steel to a re- silient post-tension concrete structure yielded environmental, structural design and cost advantages. The project team was able to trim the construction schedule time- line and secure millions of dollars in savings, while significantly reducing the project's carbon footprint and achieving points to- ward LEED certification. In addition, the project provided a strong example that a close collaboration among the concrete sup- plier, owner and design team can lead to meeting and exceeding the ambitious goals for high-performance green solutions. According to SFPUC, 525 Golden Gate consumes 32 percent less energy than sim- ilarly-sized office buildings. An integrated, hybrid solar array and wind turbine instal- lation can generate up to 227,000 kWh/year, or 7 percent of the building's energy needs. A state-of-the-art, raised flooring system incorporates the building's data and ventilation infrastructure and re- duces heating, cooling and ventilation en- ergy costs by 51 percent. Maximizing day- light harvesting saves electricity and minimizes artificial lighting, as does after- hours lighting and work station equipment automatic shutoff. EASTERN CONCRETE ADDS FOURTH BIG APPLE SITE Eastern Concrete Materials Inc., the metro New York and New Jersey subsidiary of U.S. Concrete Inc., has entered a lease and marketing agreement with Granite Ready Mix, Scara-Mix Inc. and related companies based on the southwestern side of Staten Island, N.Y. The single-site lease covers a New York State Department of Transportation- and New York City Department of Buildings- approved batch plant that provides con- crete for residential, commercial, and infrastructure projects. It will comple- ment Eastern's Master Mix, LLC, operation on the northwestern side of Staten Is- land, enabling the company to optimize its expanded fleet of 30 delivery trucks to provide full service to the island's densely populated northern and southern areas, while backing up sister ready mixed locations in nearby New Jersey. The new lease will also see Eastern mar- ket sand, stone, and recycled aggregates. The Staten Island expansion positions the company with four New York City ready mixed plants—the other two in Brooklyn— and 11 operating sites in the metro New York and New Jersey. It is part of the pro- ducer's strategy to increase its presence in the market as construction activity re- bounds. "We are pleased to have made this arrangement with the Castellano family that started this business more than 25 years ago, [and] look forward to growing our sales on Staten Island by serving the customer base with our high quality prod- ucts and safe, reliable service," says Michael Gentoso, vice president and general manger, U.S. Concrete Atlantic Division.
