Mexico City, Day 3 – Teams Investigate Building Damage

On Wednesday, the ATC reconnaissance team sub-groups were rearranged. Ramon and Jennifer’s group visited the Condesa neighborhood in the northern part of the city. Here the team assessed two buildings, one of which suffered some damage, and the other nearly none. Another group, including Laura Hernandez, focused on the southern area of Mexico City where they saw several structures with distinct damage

Mexico City, Day 2 – Engineers review Seismic Standards and Inspection Procedures

GMS engineers and the other members of the Applied Technology Council (ATC) reconnaissance team arrived in Mexico City and coordinated their plan of action to study the effects of the 9/19/2017 earthquake on building structures. Each morning, they meet at the WSP office to organize the reconnaissance for that day. Since the most severe damage was predominantly localized in several neighborhoods with poor soil conditions, in order to maximize the use of the researchers’ time, the team was divided into three smaller groups. Each went to a different section in the city to evaluate damage.

Mexico City, Day 1 – Engineers Embark on Post-Earthquake Reconnaissance Mission

GMS engineers departed for Mexico City on Monday to be joined by remaining members of the Applied Technology Council (ATC) reconnaissance team reviewing the aftermath of the 9/19/2017 earthquake. The goal of this reconnaissance mission is to perform detailed assessments of reinforced concrete structures with all levels of damage. The reconnaissance will focus on identifying the likely cause of collapse in concrete buildings that performed poorly, and the likely cause of good performance in non-collapsed buildings in the immediate vicinity.

GMS Engineers on ATC Reconnaissance Team Deployed to Assess Mexico City Aftermath

Mexico is one of the world’s most seismically active regions, sitting atop several intersecting tectonic plates. On September 19, 2017, a magnitude 7.1 earthquake hit the Greater Mexico City area killing 370 people and collapsing 40 buildings. The quake occurred on the 32nd anniversary of the 1985 Mexico City earthquake, which killed around 10,000 people. The 1985 quake was commemorated, and a national earthquake drill was held, at 11 a.m. local time, just two hours before the 2017 earthquake. Twelve days earlier, the even larger 2017 Chiapas earthquake struck 400 miles away, off the coast of the state of Chiapas.

In support of ongoing U.S. Government-funded research and development projects in earthquake engineering, the Applied Technology Council (ATC) Endowment Fund is sponsoring a team of experts to investigate the performance of buildings in Mexico City following the event.

Monitoring and Pre-construction Services

There are approximately 50,000 buildings on the 22.8 square mile island of Manhattan and the majority of construction occurs in densely built areas only a few feet from occupied buildings. When your neighbor builds or renovates, there may be residual effects on your property.

New Rain Screen at Adidas Flagship

The largest of its stores globally, Adidas’ new North American flagship at 565 Fifth Avenue in New York City spans four floors, including a lower level,  and occupies approximately 45,000 sf. The overall design was conceived with the theme of sports and high school stadiums. In particular, the entry tunnel, reminiscent of a stadium entry, is made up almost entirely of glass with some stainless steel hardware and connectors; this load bearing glass structure at street level includes a glass ceiling and glass walls. The previous storefront was replaced with new glass panels spanning over 16 feet, supported only at the base and the head.

Stapleton Library Wins 2017 AIA/ALA Award

Every year, the American Institute of Architects partners with the American Library Association/Library Leadership and Management Association to honor the best in library architecture and design across the nation. The AIA/ALA Library Building Award is the only award that recognizes entire library structures and all aspects of their design. One of this year’s eight awards was bestowed upon Stapleton Library for its reconstruction and new addition.
