Vision Task Force Foretells How Projects Will Be Built in 2021
Posted by Tasha Weiss on May 16, 2014 at 10:02 AM.
The Vision Task Force of the National Institute of Building Sciences’ buildingSMART Alliance has launched www.nationalbimstandard.org/vision2021, a new website that offers a glimpse into the not-too-distant future of the building industry.
The Alliance is the developer of the nation’s BIM standard, the National BIM Standard - United States (NBIMS-US). Its NBIMS-US Planning Committee formed the NBIMS-US 2021 Vision Task Force (VTF) last year to focus on defining, forecasting and, in some cases, guessing at the future of the building industry to gain insight into what the NBIMS-US will need to be able to support that future.
“The initial effort of the 2021 Vision Task Force was to ask subject matter experts from every part of our industry to provide short essays about the nature of their role, profession or industry as it will be in 8-10 years – a timeframe we believe it is possible to reasonably predict,” explained Chris Moor, chair of the NBIMS-US Project Committee and VTF, and AISC’s director of industry initiatives.
The VTF collected nearly 40 of these essays, and then spent considerable time researching additional sources about the future of the industry.
“We then wove this knowledge together into a single, compelling and tangible vision of how a construction project may be built in the future, including the technologies and processes that would be in common use,” said Moor. “We delivered this vision in both novel and newspaper article formats to capture the imaginations of different audiences.”
The website offers the reader the opportunity to download a story delivered via a choice of two literary vehicles—a short novel and a fictional newspaper article—through which to explore the design, construction and opening day of a fictional children’s care center in Springfield, U.S., and to meet the key players of the team that created the project.
Major findings among the VTF’s essays and other research used to develop the story fall into six broad categories: Sustainability; Facility Management and Operations; Data, Interoperability and Integration; Building Codes, Specifications and Standards; Technology; and Processes, Efficiency and Collaboration. All of the categories are expanded on in the summary within the publications.
But while these categories identify some of the anticipated progress of the industry during the next decade, what was more revealing was just how the industry might get there.
“Everything we discovered points to an industry looking for solutions; looking for a better way. And it’s up to the owners, the government and everyone who wants our industry to succeed to embrace the challenge of finding those solutions,” added Moor. “We have to find a way to get there. We need mandates, investment, a cultural shift and a brand new educational platform to help the industry become more efficient.”

You can also meet George Jetson, the steel fabricator of the future, in Moor’s article “Tomorrowland” from the October 2013 issue of MSC.

Steel Shots: A New Way to Ride
Posted by Tasha Weiss on May 9, 2014 at 4:31 PM.
The new Denver Union Station Bus Concourse opens on Sunday, marking a critical milestone for the city’s precedent-setting intermodal hub. Its SOM-designed Train Hall canopy (shown above), an efficient and formally expressive means of sheltering multiple railway tracks, comprises 11 steel arch trusses spanning nearly 180 ft, clad in bright white tensioned fabric.

Today, the Denver Regional Transportation District (RTD) will mark the opening of the Union Station Bus Concourse with a grand ribbon-cutting celebration that will include remarks from U.S. Secretary of Transportation Anthony Foxx, numerous state and local officials, RTD General Manager Phil Washington and other dignitaries. The bus concourse is a vital component of the new Denver Union Station Intermodal Hub, the centerpiece of RTD’s FasTracks transit expansion program. Skidmore, Owings & Merrill LLP (SOM) designed the intercity bus terminal and the broader Denver Union Station complex; the firm also developed the master plan for the surrounding transit-oriented neighborhood. Service at the Union Station Bus Concourse will begin on Sunday.
Denver’s historic Union Station is a Beaux Arts gem located on the edge of downtown. SOM was commissioned to expand and transform this station into a major regional transportation hub. To do so, the firm converted 20 acres of former rail yards into an urban transit district that orchestrates light rail, commuter and intercity rail, bicycle and bus routes, and pedestrian pathways into an intuitive intermodal hub. The Union Station Bus Concourse is situated at the heart of this vibrant network, directly beneath the rail station.
“This project represents a major investment in transit-oriented development with extraordinarily far-reaching social and economic consequences,” said Roger Duffy, design partner. “The bus concourse is the result of nearly a decade of thoughtful public consultation and bold design. Its completion helps realize this community’s aspirations for a truly transformational neighborhood and landmark public project.”
Measuring 980 ft in length, the 22-gate underground bus concourse services 16 regional, express and local bus routes. The terminal serves a dual purpose as a subterranean pedestrian concourse that connects the constellation of transportation programs distributed across the site. Vivid colors and natural lighting help passengers orient themselves, whether they are boarding buses, navigating to the light rail or commuter rail stations or ascending into the capital city.
The Train Hall canopy comprises 11 steel arch trusses spanning nearly 180 ft, clad in bright white tensioned fabric. In profile, the canopy rises 70 ft at either end and descends in a dynamic sweep to 22 ft at the center, a gesture that allows the structure to protect the passenger platforms below, while remaining clear of the view corridor established to protect views of the historic station. In addition to Amtrak service, four commuter rail lines are scheduled to open in 2016 and 2018.
