Structures and Architecture - Proceedings of the 3rd International Conference on Structures and Architecture, ICSA 2016 | Year: 2016
This paper presents a collection of web based technologies designed to enhance the collaboration between architecture, engineering, construction, and owner (AECO) project teams. With advances in digital design, documentation, and communication methods in recent years - a need has developed for better integration of the often disparate digital workflows of each team. By utilizing web based frameworks and custom software development, bespoke applications may be developed that enable project teams to rapidly share and discuss design intent. The nature of the projects discussed will center around two common themes: rapid communication between individuals operating in different disciplines of a collaborative project and increasing the design space able to be studied during the design phases of a project. The case studies will highlight how utilizing web technologies may alter the stream of information across disciplines, changing how we collaboratively design and engineer buildings. © 2016 Taylor & Francis Group, London.

A coalition of 12 architect-engineer-contractor groups in New York state is hoping the third attempt since 2013 to get an emergency responder bill passed and signed into law will be successful. The New York Emergency Responder Act would limit liability of design professionals and other emergency responders hired by authorities to provide assistance during post-disaster search, rescue and recovery operations. Both versions of the bill—Senate 4135, sponsored by Diane J. Savino (D), and Assembly 4241, sponsored by Steve Englebright (D)—are in committee. To be voted on, each version needs to be on the floor of the senate or assembly at least three days in advance of June 15, when the current legislative session ends. “The next two weeks are critical for us,” says Jay Simson, president of the American Council of Engineering Cos. New York. ACEC NY, a coalition member, is spending time educating legislative leadership to help the bills reach the floor. The act states that volunteers or those under contract—individuals or corporations—that render emergency assistance shall “not be subject to suit or claim, nor liable for any personal wrongful death, property damage, economic loss or any other damage or claim … relating to the rendering or furnishing of voluntary or contractual emergency assistance in connection with the disaster or emergency.” The exception to the immunity is “work performed in a manner that constitutes wanton, willful or intentional misconduct, or gross negligence.” The Structural Engineers Association of New York, a coalition member, has been pushing for an emergency responder act for 12 years, in response to events following the Sept. 11, 2001, terrorist attacks on the World Trade Center. After 9/11, teams of structural engineers, organized by SEAoNY, spent four months—24/7—at Ground Zero to help assess the structural stability of the debris pile and any remaining structures so that other emergency responders—firefighters, police and contractors—could more safely do their work of search, rescue, recovery and debris removal. New York City had contracted with the engineers as subcontractors to the city’s lead structural firm, Lev Zetlin Associates-Thornton Tomasetti. Beginning in 2006, plaintiffs—at least a third of whom are firefighters and police—filed lawsuits against the city and its contractors, which included 22 structural engineering firms. The number of separate lawsuits filed against each defendant eventually surpassed 30,000. The major complaint was that Ground Zero-area workers were not given proper respiratory equipment and were exposed to thousands of toxins in the air. About 5% of the suits have not been settled. Early on, structural engineers lost legal attempts to be dismissed from the suits, on grounds their services had nothing to do with air quality (ENR 6/25/07 p. 78). “The city, which had a $3-billion captive insurance policy for all the engineers and contractors, said, ‘Don’t worry,’ ” says Joseph F. Tortorella, president of Robert Silman Associates, one of the 22 engineers named in the suits. “I always said, ‘We should be worried,’ ” he adds. Silman has spent more than $100,000 on lawyers to review the suits’ legal documents. “This falls into the category of ‘let no good deed go unpunished,’ ” says Tortorella, who himself has health issues associated with exposure to bad air at Ground Zero. Glenn R. Bell, in 2001 the CEO of Simpson Gumpertz & Heger, hasn’t kept track of how much SGH, also a defendant, has spent on lawyers. After 9/11, the Boston office sent nine engineers to New York City to assist with rapid damage assessment and long-term recovery efforts. SGH had decided “to do the right thing,” knowing its insurance might not cover any lawsuits, says Bell, now a senior principal. “We were in an advisory role, working shoulder-to-shoulder with the fire department and the contractors,” he says. “We were not there to direct work.” Design professionals say the legislation is also needed for the public good. Without limited immunity, most engineers will be reluctant to get involved assisting after the next disaster, they maintain. Tortorella is an exception. “I know I will volunteer again if needed,” he says.

As the second month of the 2017 Major League Baseball season swings into full gear, the Mid-Atlantic Precast Association (MAPA) takes a look at the building of the Washington Nationals Ballpark project, featuring one of their producers, Universal Concrete Products Corporation. Nationals Park, located in Washington, D.C., is home to the Washington Nationals baseball franchise. It was the first professional sports venue to be awarded LEED Silver certification by the U.S. Green Building Council (USGBC). LEED is a building rating system that serves as a nationally-recognized standard for sustainable building design. The Nationals project was completed in 2008. Today, more than 15 professional sports venues have received LEED certification for new construction or existing building renovations. Project Overview In addition to achieving LEED certification, owners of the Nationals franchise wanted a distinctive look for their new ballpark that projected a contemporary, vibrant feeling while still meshing with the limestone of many of the institutional buildings of the city. To achieve this, designers created an exterior façade for the stadium that combines steel, glass, and architectural precast concrete panels. The precast concrete stadium components were produced by Universal Concrete Products Corporation, located in Stowe, PA. Precast Solution The panels, featuring a buff-colored texture that resembles limestone, interface seamlessly with the other materials. They were finished with a range of light to heavy sandblasting to create variety. White cement and local aggregates were used in the mix. The local materials and other attributes contributed to the precast concrete’s factors that helped the building achieve its Silver LEED rating. The panels were manufactured locally, minimized construction waste and provided other benefits. Overall, the building is one of the greenest public facilities in the nation.

A new web-based, structural-engineering BIM collaboration platform is providing its developers with a few surprises about how the product is being used, with more small projects loaded than expected. The Combine, an Atlanta-based software firm, developed Konstru in partnership with engineering firm Thornton Tomasetti’s technology incubator TTWiiN, which supplied the industry expertise. After a beta launch this spring, Combine co-founder and partner K.P. Reddy says, “What we’re really learning is that, although we expected it would solve a lot of complicated, hard problems, it’s being used for a lot of simple problems a lot of the market is dealing with. We thought adoption would be on the biggest, most complicated projects, but we’ve seen plenty of smaller and midsize [projects], like schools and office buildings.” The Combine provides seed-stage expertise to develop and commercialize new technologies. It launched Konstru as a new “portfolio company” through the partnership with Thornton Tomasetti. In the first half of 2017, the team plans to spin off five companies, each of which will seek Series A investor funding. Konstru was the first. Reddy says Konstru is a web-based platform that lets engineers collaborate via browser while letting them continue to use the tools they are accustomed to, such as Microsoft Excel, Autodesk Revit, Trimble’s Tekla, Bentley’s RAM Structural System, Grasshopper, and CSI’s ETABS and SAP2000. “Konstru is neutral. We’re the glue in the middle,” says Reddy. Serving smaller firms and projects is a good market to land in “because those companies are largely ignored,” Reddy adds. “Small firms get priced out.” Konstru is competing with Autodesk’s BIM 360 portfolio of real-time design collaboration tools and especially BIM 360 Glue, which is seeing increased adoption, says Sarah Hodges, director of the construction business line for Autodesk. The industry is “waking up to this notion” of digitizing construction, she says. Ricardo Khan, Sr. Director of Project Solutions at Mortenson Construction, says his team investigated Konstru and predicts Konstru “will be competing with Autodesk BIM 360 platform, specifically around [Autodesk’s] Glue application and the services Autodesk is building around BIM 360." Konstru is optimized for structural engineers and contractors especially with distributed teams. "It is always interesting to see new solutions emerge on the market to drive competition,” Khan says. A 2016 survey by the Associated General Contractors of America and Sage Group found that 63% of construction businesses that use or are planning to use cloud-based platforms are doing so to improve access to information from any location, although many respondents noted that technical advances with 4D and 5D modeling tools, among others, are outpacing improvements in collaboration and communications.

Earth Day 2016 will be a truly historic event. At the United Nations in New York City, more than 150 countries will sign the Paris Agreement that was forged at COP21. The signing by so many, this quickly, is unprecedented. By signing the agreement, countries large and small, rich and poor, will give their consent to be bound and the agreement will “enter into force.” A strong global climate agreement and the transition to a low-carbon economy are in the best interests of the global economy and future generations. We are proud to stand alongside over 100 other companies in formally welcoming the Paris Agreement, congratulating world leaders on reaching this ambitious climate change accord and encouraging timely implementation of the climate commitments laid out in the sgreement. We are pleased to be joined in the congratulatory statement and call for a “Low Carbon USA” by USGBC members including Autodesk, Colgate Palmolive, Dupont, Enernoc, General Mills, HP, Hilton, JLL, Johnson & Johnson, Kingspan, Mortenson Construction, National Grid, Nike, Pacific Gas & Electric, Perkins + Will, Philips, Schneider Electric, Sealed Air, Starbucks, Thornton Tomasetti and Vermont Energy Investment Corporation. Across the globe a majority of people—and government officials—now recognize the threat of climate change. Science, education, media and increasingly severe natural disasters have made this real. But that awareness alone is unlikely to have enabled the agreement. The upsurge in implemented clean energy and energy efficiency has been critically important in showing that decarbonization is a real option and can be achieved hand in hand with a strong economy and necessary development. To get there, governments have led by example and flexed policy levers to support research and development (R&D) and drive new markets; the finance world has responded with record-breaking investment; corporations have responded with innovative technologies and bringing ideas to scale. Historic as it is, the Paris Agreement is a starting point for the accelerated transformation we need. We recognize that the hard work has now only just begun. We must now focus our efforts and attention on the agreement’s proper implementation. Governments will need to boost R&D and adopt more reaching policies, such as the Clean Power Plan; more investors will need to prioritize clean energy and sustainable attributes in their portfolios; and businesses will need to keep innovating and putting solutions into the marketplace. And closer to home, each of us has a role, as a citizen and voter, and in our own lives. Wherever you fit in, all of us have a role to fulfill. For tomorrow, let’s pause to appreciate the historic moment, and get back to work. We can’t afford to waste any more time.

This manuscript summarizes recent work to determine if the LRFD resistance factor for cold-formed steel compression members can be increased above its current value of 0.85. An experimental database of 675 concentrically loaded columns with plain and lipped C-sections, plain and lipped Z-sections, hat sections and angle sections, including members with holes, was compiled. The predicted strength of each specimen was calculated with the American Iron and Steel Institute's Main Specification and the Direct Strength Method, with the Direct Strength Method making more accurate strength predictions, especially for columns with partially effective cross sections. The LRFD resistance factor, calculated with a first order second moment reliability approach, was consistent with that currently specified in the code for both the Main Specification and the Direct Strength Method. Capacity predictions of columns failing by the distortional buckling limit state were more accurate than columns failing by global buckling or local-global buckling interaction. The test-to-predicted strength ratios for single angle columns were highly variable, with capacity predictions becoming excessively conservative with increasing global slenderness. © 2011 Elsevier Ltd.
