Fortune 500 A/E/C Firm Inks Lease at LEED Silver 100 Park Avenue

Publicly-traded AECOM is moving into 100,000 square feet of space at the LEED Silver-certified 100 Park Avenue.

100 Park Avenue

Another fourth quarter transaction we want to make sure we note here at gbNYC is Los Angeles-based AECOM’s 12-year, 110,000-square-foot deal at SL Green’s LEED-EB:OM Silver-certified 100 Park Avenue, which was announced in mid-December. AECOM, as you may know, is a publicly-traded design and construction firm which both Architectural Record and ENR ranked as the country’s top design firm for 2010. The company also ranks number 352 on the Fortune 500 and recently purchased Tishman Construction (which, interestingly, built 100 Park Avenue back in 1950). AECOM will move into space on the 5th, 6th, 18th, and 19th floors, consolidating office locations that are currently scattered across the Grand Central submarket.

SL Green earned LEED Silver for 100 Park Avenue back in August of 2009 after a $72 million capital improvement program (designed by Moed De Armas & Shannon with construction management services from – you guessed it – Tishman’s interiors division), which included upgrades to the building’s infrastructure, lobby, elevators, and facade. BOMA named 100 Park Avenue its Best Renovated Building of the Year for 2008-09; at last glance, asking rents at the tower were between $60 and $80 per square foot, depending on the floor. Figures for the AECOM lease do not appear available. Other tenants at 100 Park Avenue include BDO Seidman, Wells Fargo, and Aetna.

Originally designed by architects Kahn & Jacobs, the 36-story 100 Park Avenue was the first of Park Avenue’s International Style high-rises. Located at the corner of East 40th Street, the modern glass and steel tower was completed in 1949 and replaced the Murray Hill Hotel, which dated from 1883 and whose residents strongly fought against the new development.
