In this section, Informed Infrastructure compiles infographics from trusted sources that reveal insight on infrastructure spending. We also compile some of the top infrastructure stories that shouldn’t be missed. For ongoing news coverage, turn to Informed Infrastructure online (www.informedinfrastructure.com), our Twitter feed (@IInfrastructure) and our weekly e-newsletter.

The American Iron and Steel Institute (AISI) published AISI D102-23, “Illustrative Examples for Provisions in AISI S100-16 (2020) w/S3-22.” The document provides a set of 22 design examples that illustrate updated provisions included in AISI S100-16(2020) w/S3-22, North American Specification for the Design of Cold-Formed Steel Structural Members, 2016 Edition (Reaffirmed 2020) with Supplement 3, 2022 Edition. The examples were developed using the software Smath Studio and can be purchased from the AISI Steel Store (shop.steel.org) or directly at ow.ly/4A1R50PEAaM.

“Supplement 3 includes many significant changes and additions to the North American Specification,” said Jay Larson, P.E., F.ASCE, managing director of AISI’s Construction Technical Program. “AISI created these design examples to assist engineers in understanding those changes, to aid programmers in including them in updates to their software and to demonstrate to designers how to incorporate them into future projects.” He noted that the Smath Studio software required to access the design examples is free of charge to use.

The Federal Transit Administration (FTA) is making $13.4 million in grants available via a notice of funding opportunity (bit.ly/3Zj6ttk) through its Pilot Program for Transit-Oriented Development (TOD) planning program.

The funding aims to support local planning and investment near transit hubs to promote “sustainable, livable and equitable communities.” The agency said its TOD planning program seeks to link public transportation, land use and housing to create communities that are connected to transit and walkable.

The agency added that “special consideration” for these grants is given to projects that seek to improve air quality, advance environmental justice, support unhoused populations and promote housing affordability.

FTA also noted that grant applications in 2023 from areas with a lower population density or lower average income compared to surrounding areas will receive a higher federal funding share. Additionally, applications with a substantial focus on affordable housing may receive up to 100 percent federal cost share support.

To promote a shift in practice, mindset and culture, the Digital Twin Consortium (DTC) published “A Whole Systems Approach to Decarbonization Across the Building Lifecycle,” the third in its series of five user guides for smart buildings stakeholders. The authors explain that to reduce (and eventually reverse) environmental damage, we need to re-imagine our buildings, cities and infrastructures.

According to the latest guide (available at bit.ly/3PjDelc), designers and developers need to approach buildings holistically as indivisible components of a larger, constantly regenerating and self-sustaining system. The authors propose embedding sustainability and high energy performance into buildings, starting early on with the design phase all the way through to daily operation.

The user guides are a compendium to a white paper “Decarbonizing the Built World: A Call to Action,” published earlier in 2023 by the DTC’s AECO Tiger Team (download at bit.ly/3RfJMEj). They were created to provide owners with an understanding of the capabilities and potential impact of digital twins at all stages of the building decarbonization lifecycle.

Spectacular Bridges Grace Stamps


The U.S. Postal Service issued four new Presorted First-Class Mail stamps featuring striking photographs of bridges. The stamp art features four bridges completed between 1938 and 2022: the multi-span steel through arch Arrigoni Bridge connecting the Connecticut municipalities of Middletown and Portland; the S-curved cable-stayed Bob Kerrey Pedestrian Bridge between Council Bluffs, Iowa, and Omaha, Neb.; the steel truss Skydance Bridge topped by a public sculpture in Oklahoma City; and the basket-handle twin arch Iowa-Illinois Memorial Bridge connecting Bettendorf, Iowa, and Moline, Ill.

Society of Women Engineers (SWE) award recipients include professionals; collegiates; and groups from influential businesses, corporations and universities across the globe.

“SWE Awards provide a platform to elevate and highlight career, academic, and service achievements of engineers and technologists that advance the mission of SWE through inspiring others,” said Alexis McKittrick, Ph.D. and FY24 president of SWE. “These award winners are shining examples for our members and the entire engineering community of how to ‘Live Without Limits.’”

This year’s award recipients will be recognized at WE23, the world’s largest conference and career fair for women engineers and technologists, on Oct. 26-28, 2023, in Los Angeles. A listing of all awardees can be found at bit.ly/3PBCXLR.
