Gutierrez, Secretary Technology Administration Michelle O'Neill, Acting Under Secretary for Technology National Institute of Standards and Technology William Jeffrey, Director Disclaimer No. 1 Certain commercial entities, equipment, products, or materials are identified in this document in order to describe a procedure or concept adequately or to trace tlie liistory of the procedures and practices used. Such identification is not intended to imply recommendation, endorsement, or implication that the entities, products, materials, or equipment are necessarily the best available for the purpose. Nor does such identification imply a finding of fault or negligence by the National Institute of Standards and Technology. Disclaimer No. 2 The policy of NIST is to use the International System of Units (metric units) in all publications. In this document, however, units are presented in metric units or the inch-pound system, whichever is prevalent in the discipline. Disclaimer No. 3 Pursuant to section 7 of the National Construction Safety Team Act, the NIST Director has determined that certain evidence received by NIST in the course of this Investigation is "voluntarily provided safety-related information" that is "not directly related to the building failure being investigated" and that "disclosure of that information would inhibit the voluntary provision of that type of information" (15 USC 7306c). In addition, a substantial portion of the evidence collected by NIST in the course of the Investigation has been provided to NIST under nondisclosure agreements. Disclaimer No. 4 NIST takes no position as to whether the design or construction of a WTC building was compliant with any code since, due to the destruction of the WTC buildings, NIST could not verify the actual (or as-built) construction, the properties and condition of the materials used, or changes to the original construction made over the life of the buildings. In addition, NIST could not verify the interpretations of codes used by applicable authorities in determining compliance when implementing building codes. Where an Investigation report states whether a system was designed or installed as required by a code provision, NIST has documentary or anecdotal evidence indicating whether the requirement was met, or NIST has independently conducted tests or analyses indicating whether the requirement was met. Use in Legal Proceedings No part of any report resulting from a NIST investigation into a structural failure or from an investigation under the National Construction Safety Team Act may be used in any suit or action for damages arising out of any matter mentioned in such report (15 USC 281a; as amended by P.L. 107-231).

NISTNCSTAR 1-8, WTC Investigation iv Dedication On September 11, 2001, the City of New York was attacked by terrorists who flew large commercial aircraft into the twin towers of the World Trade Center. Immediately, emergency responders from across the city began operations to protect the citizens of New York City and to save lives at the World Trade Center. With these efforts, many emergency responders gave their lives, and many more were seriously injured. The injuries from this attack were more than physical. The emotional toll for these emergency responders and their families will always be with them. This report is dedicated to all the emergency responders who lost their lives that morning, to all emergency responders who were injured, and to all emergency responders and the families who live with the anguish caused by this attack. NISTNCSTAR 1-8, WTC Investigation V Dedication This page intentionally left blank. NISTNCSTAR 1-8, WTC Investigation vi Abstract The September 11, 2001, attack on the World Trade Center (WTC) caused the deaths of 2,749 people. Included in the group were approximately 421 emergency responders from The Fire Department of the City of New York (FDNY), The New York City Police Department (NYPD), the Port Authority Police Department (PAPD), The Port Authority of New York and New Jersey (PANYNJ), from WTC security firms, and volunteer emergency responders who were in the WTC area of the city when the attack occurred. This report addresses the operations of these emergency responders, the technologies used during WTC operations, and the guidelines and practices that governed these operations. The objectives of this study were to 1 ) fully document what happened during the response by the emergency services to the attacks on the WTC, up to the time of collapse of WTC 7; (2) identify issues that need to be addressed in changes to practice, standards, and codes; (3) identify alternative practices and/or technologies that may address these issues; and (4) identify R&D needs that advance the safety of the fire service in responding to massive fires in tall buildings. The approach taken was to conduct a comprehensive search for data related to the emergency response on September 1 1, 2001, analyze the data, and report on the findings. Data gathering included the collection of written documents, electronic recordings, visual data (both photographs and video), and first-person accounts of what happened during WTC operations. Results from this investigation show that the emergency responders were faced with the greatest disaster of the last 100 years in the United States. The emergency responders had one common focus: to save as many victims of this attack as possible. During the response, emergency responders had to function under war-like conditions as they carried out their rescue and evacuation efforts. Emergency responders operated with equipment, human endurance, and emergency response practices that were stretched well beyond normal limits. This report discusses how the emergency response activities and equipment were challenged. The emergency responders paid a heavy price in the loss of hundreds of their own lives when the WTC buildings collapsed. This study focused on the following topics: • emergency responder dispatch and response to the WTC • emergency responder access to the WTC site and towers • command and control associated with the emergency response • coiTununications during operations and the of communications in tall buildings • firefighting in high-rise buildings and the evacuation from the WTC towers • emergency responder situational awareness and the physiological impact of conducting operations in tall buildings Keywords: Buildings, emergency responders, emergency medical service, evacuation, firefighters, firefighting, police, rescue, search, World Trade Center.

Fusscas Submitted to the Department of Urban Studies and Planning, in partial fulfillment of the Degree of Master of Science in Real Estate ABSTRACT This thesis represents a study of the New York World Trade Center. It was written in conjunction with four other papers studying World Trade Centers (WTCs) sites in Taipei, Amsterdam, Curacao and Portland (Oregon). These sites represent a cross-section of the various trade and economic environments that World Trade Centers operate in around the globe. Each of these studies examines the extent to which the owner/developer, the tenants and other regional public and private concerns have benefitted through their involvement with these highly specialized real estate developments. The New York World Trade Center is unique from all other World Trade Centers in several respects.

  • September 19, 2016 Manhattan to Add 20M Sf of New Office Space By
    September 19, 2016 http://therealdeal.com/2016/09/19/manhattan-to-add-20m-sf-of-new-office-space-by-2021/ Manhattan to add 20M sf of new office space by 2021 The space will be spread across 23 buildings: New York Building Congress By Kathryn Brenzel Over the next five years, more than 20 million square feet of new office space is expected to be added to Manhattan. The office space is spread across 23 new buildings, with much of it — approximately 6.5 million square feet — concentrated in Related Companies and Oxford Properties Group’s Hudson Yards projects, according to a new report by the New York Building Congress. The organization bills the increase as a sign of a healthy office market, the best seen in the borough since the 1980s, said Richard Anderson, the organization’s president. The report only counts one building impacted by the Midtown East rezoning — SL Green Realty’s One Vanderbilt, which is expected to be completed in 2021 and will span 1.6 million square feet. More new office space is expected in the neighborhood in the coming decades. Last month, the Department of City Planning released a long-awaited proposal to rezone Midtown East, which seeks to bulk up the neighborhood’s office stock. The proposal identifies 16 sites where a total of 6.5 million square feet of new office space could be added under the rezoning. The proposal, however, estimates that this construction would be completed by 2036 — and it’s not yet clear how many of the property owners at the 16 sites will be on board with adding office space.

The qualitative component of the thesis investigates the history behind the stalled development of Towers 2 and 3 and examines a potential contingency that could have mitigated the market risk. The quantitative component builds upon that story and creates a hypothetical Real Options case as a framework for applying and valuing building use flexibility in a large-scale, politically charged, real estate development project.

  • Mysteries of the Twin Towers a Survey of Available Evidence on the Collapse of the World Trade Center Towers R
    Mysteries of the Twin Towers A Survey of Available Evidence On the Collapse of the World Trade Center Towers R. Herbst; BAAE, ME Rev. 12.0 February 2009 The WTC Complex [1] Thanks to Eric Hufschmid, Dave McGowan, and the webmaster of serendipity.li for explicit permission in the posting of images. Thanks to Sami Yli-Karjanmaa for corrections to the text in discussing his 9/11 activism. Special thanks to Connie Eichenlaub for help in text editing up through version 11. Background According to media reports, American Airlines Boeing 767 Flight 11 crashed between floors 94 and 98 of the North Tower at 8:46 a.m. The North Tower collapsed at 10:29 a.m. According to media reports, United Airlines Boeing 767 Flight 175 crashed between floors 78 and 85 of the South Tower at 9:03 a.m. The South Tower collapsed at 9:59 a.m. Crash and collapse times are based on seismic data from the Lamont-Doherty Earth Observatory in Palisades, New York. US Department of State times were essentially identical, except time of collapse of the South Tower was given as 10:05 a.m ., rather than 9:59 a.m. According to the State Department, 92 people were on board Flight 11, and 64 people were on board Flight 175. [2] Architect Minoru Yamasaki was commissioned to design the World Trade Center with the New York firm of Emery Roth and Sons. Structural engineers John Skilling and Leslie Robertson of Worthington, Skilling, Helle and Jackson (WSH&J), the Seattle based World Class structural engineering Firm of Record, worked on the project.

  • Chapter 5. Historic Resources 5.1 Introduction
    CHAPTER 5. HISTORIC RESOURCES 5.1 INTRODUCTION 5.1.1 CONTEXT Lower Manhattan is home to many of New York City’s most important historic resources and some of its finest architecture. It is the oldest and one of the most culturally rich sections of the city. Thus numerous buildings, street fixtures and other structures have been identified as historically significant. Officially recognized resources include National Historic Landmarks, other individual properties and historic districts listed on the State and National Registers of Historic Places, properties eligible for such listing, New York City Landmarks and Historic Districts, and properties pending such designation. National Historic Landmarks (NHL) are nationally significant historic places designated by the Secretary of the Interior because they possess exceptional value or quality in illustrating or interpreting the heritage of the United States. All NHLs are included on the National Register, which is the nation’s official list of historic properties worthy of preservation. Historic resources include both standing structures and archaeological resources. Historically, Lower Manhattan’s skyline was developed with the most technologically advanced buildings of the time. As skyscraper technology allowed taller buildings to be built, many pioneering buildings were erected in Lower Manhattan, several of which were intended to be— and were—the tallest building in the world, such as the Woolworth Building. These modern skyscrapers were often constructed alongside older low buildings. By the mid 20th-century, the Lower Manhattan skyline was a mix of historic and modern, low and hi-rise structures, demonstrating the evolution of building technology, as well as New York City’s changing and growing streetscapes.

  • Negotiating the Mega-Rebuilding Deal at the World Trade Center: Plans for Redevelopment
    NEGOTIATING THE MEGA-REBUILDING DEAL AT THE WORLD TRADE CENTER: PLANS FOR REDEVELOPMENT DARA M. MCQUILLAN* & JOHN LIEBER ** Good morning. The current state of Lower Manhattan is the result of multiple years of planning and refinement of designs. Later I will spend a couple of minutes discussing the various buildings that we are constructing. First, to give you a little sense of perspective, Larry Silverstein,1 a quintessential New York developer, first got involved at the World Trade Center and with the Port Authority, owner of the World Trade Center,2 in 1980 when he won a bid to build 7 World Trade Center.3 In 1987, Silverstein completed the seventh tower, just north of the World Trade Center site.4 As Alex mentioned, 7 World Trade Center was not the most attractive building in New York and completely cut off Greenwich Street. Greenwich Street is the main street running through Tribeca and connects one of the most dynamic and interesting neighborhoods in New York to the financial district.5 Greenwich serves as a major link to Wall Street. I used to live in SoHo. I would walk to work at the Twin Towers every morning down Greenwich Street past the Robert DeNiro Film Center, Bazzini‘s Nuts, the parks, and the lofts of movie stars, and all of a sudden I would be in front of a 656-foot brick wall of a building. There were huge wind vortexes which often swept garbage all over the place, you could never get a cab, and it was a very * Vice President of Marketing and Communications for World Trade Center Properties, LLC, and Silverstein Properties, Inc.
