The Rise of the Skyscraper City:
All the Tall Buildings in Manhattan, 1874-1900
In conjunction with its current exhibition TEN & TALLER, 1874-1900, The Skyscraper Museum presents symposium that explores new narratives of the first decades of high-rise history. Organized into four sessions, on Thursday evening, March 9 and on Friday morning and afternoon, March 10, the symposium brings together a range of scholars and authors who have studied nineteenth-century New York from the perspectives of architecture, engineering, and urban history.
New York’s first “skyscrapers” were erected in 1874, initiating the city’s ascent into the vertical. The all-masonry Tribune and Western Union buildings were ten-story office buildings that lifted their decorative towers to 260 and 230 feet. By 1900, the steel skeleton of the 30-story Park Row Building – tallest in the world–topped out at 391 feet.
In the last quarter of the 19th century, Manhattan added 250 buildings of ten or more stories – more than triple the number of Chicago. Elevators and new methods of construction enabled this rise, but it was the phenomenal growth of the city itself, whose population swelled from less than a million in the 1870s to more than 3.4 million in 1900, that drove New York into its vertical expansion.
In particular, the symposium will explore a new narrative of “All vs. Tall” that considers other uses beyond office buildings, including apartments, hotels, and lofts, and emphasizes the commercial motive of high-rise development. The comprehensive survey of every building in Manhattan of 10 or more stories from 1874 through 1900 that is the subject of the TEN & TALLER exhibition and the three interfaces – the GRID, the MAP, and the TIMELINE – offer new ways of viewing the architectural and urban development of the period that will be a focus of our symposium.

Topic: 90 Minutes to Discharge a Concrete Truck Is This an Outdated Requirement?
Most specifications require a ready mix truck to discharge the concrete within 90 minutes after the
cement had been mixed with water. This requirement is given in ASTM C-94, the standard for ready mix concrete.
This standard has existed for over 30 years. Concrete technology has changed significantly over these years.
The cement of today is not the cement we had 30 years ago. Today, we have admixtures that can delay the
cement hydration process for hours, and we have admixtures that can extend the desired slump life of a concrete mix.
The issue of how much time should be allowed to discharge a truck is not a simple answer, like 90 minutes.
This seminar will present:
The latest in concrete technology to extend the working time for a concrete mix;
Test data on plastic and hardened concrete that was not discharged in 90 minutes;
What others are specifying as a required time or criteria to discharge concrete.
Cas Bognacki will be the seminar moderator. There will be three presenters

Industry veteran Don Allen provides insights, photos, and details from projects that have worked, and some that have not. With over 25 years of both Engineer-of- Record and CFS specialty engineer experience, Allen will show both design examples and field photos / repairs where problems have been avoided / created / resolved on CFS framing projects. Allen will discuss each specific design challenge, why a certain approach was taken, what went right with the design and construction, and what could have been done differently for conditions that did not work. Allen will also discuss some of his recent work overseas, and how innovations worldwide are shaping CFS construction in North America.

Concrete Industry Board Educational Seminar: The Key to a Successful Project - Collaboration between the Engineer and the Contractor
Tuesday, January 31, 2017 - 12 noon
Speaker: Mike Schneider - President, American Concrete Institute (ACI) SVP, CPO, Baker Concrete Construction, Inc., Monroe, Ohio
We have all been involved with good and bad projects. One of the key differentiators between successful and unsuccessful jobs is the communication and collaboration (or lack thereof) between the engineer, contractor and other team members. This live presentation will discuss a number of items that can effect budget, schedule, quality and the safety performance of a project. The end game is to have a satisfied owner that would like to use the same project team on the next job.
The earlier the contractor is involved in the design process the more impact he can have on the project cost curve. It is imperative that the expectations of all parties are identified early and hopefully there is congruency. How do we balance the issue of design optimization versus constructability. Constructability ultimately impacts the schedule and budget. How are the tolerance interfaces between various trades (elevators, curtain wall, floor coverings) discussed before they become an issue? We will discuss the importance of a pre-construction conference that is an open discussion of the potential issues. We will look at case histories where collaboration has helped to guarantee project success.
Mike Schneider is a veteran of the concrete industry. He started with Baker Concrete Construction (Monroe, Ohio) as a Project Manager in 1978, and is currently Sr. Vice President/Chief People Officer. He also serves as the company champion of Baker’s Incident & Injury Free (IIF) Program and is responsible for safety within Baker on a Global basis. Mike has been a member of ACI since 1981 and currently serves as ACI President. He’s also an active member and past President of ASCC (American Society of Concrete Contractors). Mike is involved with the Boy Scouts of America and serves on numerous boards throughout the Cincinnati community.

The Infrastructure Summit at the New York Build Expo 2017 - 15th & 16th March, Javits Center is the leading construction and design event for New York.
This market leading two day event is a must attend for: Architects, Brokers, Developers, Planning Managers, Government, Contractors, Financiers, Construction Managers, Builders, Tradesmen plus many more.
The event and report were co-led by SEAoNY members S. Nikolaou and R. Gilsanz with participation from other SEAoNY Members from GMS and WSP|Parsons Brinckerhoff.
The event and its aftershocks led to hundreds of fatalities, thousands of injuries, tens of thousands of people homeless, serious damage and collapses to buildings and infrastructure, and economic impact estimated at 3% of the national GDP. The performance of the natural and built environment was documented in the geotechnical, structural and nonstructural aspects by the GEER-ATC reconnaissance team that visited the most affected areas. The reconnaissance has yielded datasets, lessons, and suggestions for future research on:
(i) seismological and recorded strong ground motions;
(ii) application of US rapid assessment methods;
(iii) geotechnical and infrastructure performance;
(iv) site amplification and liquefaction;
(v) structural and nonstructural effects and correlation to geotechnical effects;
(vi) critical facilities and seismically-isolated structures response;
(vii) use of advanced 3-D technologies to map drone and photo observations;
(viii) case histories documentation of successful behavior in addition to failures; and
(ix) community/government response and awareness aspects.

As examples of successful tall wood buildings proliferate worldwide, many architects are considering how to leverage wood’s sustainability and other advantages through their own tall wood designs. Intended as a practical overview for those interested in pursuing wood’s potential, this presentation will cover the “who, what, when and where” of tall mass timber buildings. Following a brief discussion of history and motivators, existing tall wood projects will be used to illustrate mass timber and hybrid components, high-rise structural design concepts, and lessons learned regarding cost and schedule. Topics will also include building code avenues for alternate designs, and available resources and support. Finally, the project architect of 475 West 18th, a proposed 10-story mass timber building in New York City currently in design—and east coast winner of the U.S. Tall Wood Building Prize Competition—will share insights regarding the design process. Discussion will include economic and sustainability impacts, approval and testing, design considerations, and challenges associated with high-rise residential typology.
