How Technology can Help Predict and Prevent the Impact of Hurricanes
The financial impact of flooding on U.S. coastal cities is crippling and with rising sea levels and coastal populations, it’s anticipated to get much worse.
When Hurricane Sandy hit coastal New Jersey and New York in 2012, it caused an astonishing $70 billion in damages. One of the worst affected areas was New York City, where the East River overflowed its banks flooding vast portions of Lower Manhattan. A 13+ foot storm surge also devastated seven subway tunnels and the Ground Zero construction site. To top that off, over 10 billion gallons of raw sewage was released into the waters around New York and New Jersey.
So what can design technology do to prevent such catastrophes in the future? In his recent blog for BIM on the Rocks, Steven Costa of Microsol Resources shared some fascinating examples of design software at work in his quest to show “How Technology and Big Data can Help Predict Impacts of Hurricanes” shared by the BIM on the Rocks blog.
To start with, Costa first quantified the impact of Sandy with visual examples generated using AutoCAD Civil 3D and Adobe Photoshop:
Costa went on to model the flooding impact in InfraWorks 360, taking advantage of the new Project Boulder for InfraWorks 360 (now available on Autodesk Labs). As Costa explains, “this technology gives you the ability to create two-dimensional (2D) flood simulations within InfraWorks 360 models.”
Using data derived from the NYC Open Data website – a clearinghouse for free GIS data. Costa’s sought to create a full scale simulation of what happened when Sandy hit Lower Manhattan. But that’s not all, Costa wanted to use this data to inform a design that would protect the region from future storm surges. Using the GIS data as “a basis for a preliminary design that addresses a very real problem,” Costa reviewed winning proposals from the he Rebuild by Design design competition and settled on one from BIG. “One solution in particular I loved was the solution proposed by BIG (Bjarke Ingels Group) in a collaborative effort with a number of planners, architects and engineers known as the “Big U” or “Dryline,” said Costa.
After reviewing some of the public documentation from BIG, Costa used Civil 3D and 3ds Max to create a design simulation that could prevent further storm surge flooding. Then, using Infraworks 360 and the Project Boulder technology preview Costa created a timelapse video approximating the storm surge that impacted lower Manhattan during Hurricane Sandy. The exiting conditions were then examined in a side-by-side comparison with an approximation of the berms proposed in Bjarke Ingels Group design concept for the Dryline.
Here’s the result:

Transition periods are never easy. As businesses move from routine practices to uncertain situations, there’s a level of trepidation involved. Thankfully, there are ways to ease this anxiety—namely, by shedding light on the gap in old vs. new practices. At a time when many organizations are either in the middle of transition or running up against it, investment in visibility is imperative.
Nowhere is visibility more important than facility planning. Facility managers need oversight as they begin to adapt assets and workflows in the near-term and for the future.

The COVID-19 pandemic has been disruptive to physical workplaces for so many reasons. One of the biggest challenges for businesses has been adapting offices to new and often equally disruptive safety standards – social distancing, sanitization, contact tracing, etc. While there’s keen emphasis on these practices, indoor air quality (IAQ) in many offices is only now getting the attention it deserves.

Healthcare facility management is complex, especially since many organizations are open around the clock. Ensuring yours is at its best is expensive. Maintaining a building properly accounts for more than 80 percent of the total cost of operations and occupancy. Safety regulations constantly change. Patients arrive and depart on a variety of timelines. Healthcare workers regularly use spaces like break rooms and storage areas.

Does your business have a single source of truth when it comes to data sharing across facilities? Ensuring data is accurate, relevant, and structured is something any business can recognize as important, yet it is more difficult to achieve than most realize. Just because you are use an integrated workplace management system (IWMS) or have relevant GIS data doesn’t mean it provides a single source of truth.

Americans spend about 90% of their time indoors, according to EPA reports. Whether it is their home, workplace, or another location, people depend heavily on a controlled environment. Everything from the air we breathe to the light we bask in is artificial or at least managed.

Out of sight, out of mind. It’s all too easy to forget about asset maintenance when the assets themselves aren’t right in front of you. During the COVID-19 pandemic, this became more evident as employees went home and logged into a virtual workplace instead of coming to a physical space.

There are two distinct factions when it comes to working from home: those who relish it and those who despise it. Before COVID-19, working from home was a perk. When the pandemic hit, work-from-home (WFH) became a necessity to combat the virus’s spread. One person’s dream; the other’s nightmare.
As COVID-19 rolls on, employers are dealing with two sides of a war between those who want to return to the office and those who’d prefer working from home. Depending on who you ask, results are mixed:

The modern workplace is a far cry from spaces of the past. Banks of private offices gave way to an open concept fad that’s morphed into a hybrid of spaces, including personal desks surrounded by pony walls, hot and hotel desks, and collaboration areas.
COVID-19 threw workplace and space management into turmoil, but the return-to-work movement is underway. As employees come back to offices, stores, factories, and other businesses, the need for privacy in the workplace again takes center stage.

Mixed-use spaces – used by public sector agencies for different purposes – or even mixed-use cities present unique challenges for workplace managers under the cloud of COVID. Unlike single-use facilities, mixed-use spaces may see much larger groups of people come and go. Monitoring the health of every individual is likely impossible without strict contact tracing standards.

Historic buildings hold a special place in the hearts of architects, workplace planners, and employees. There’s something alluring about creating workspaces within the confines of century-old stone or retrofitting a Victorian Era home into offices.
For all their uniqueness, repurposing historic buildings for modern workplaces isn’t as easy as replacing a few light fixtures and brushing on a new coat of paint. Most older structures are governed by sometimes-strict regulations overseen by historic districts – the first was created in South Carolina in 1931.

The benefits of the Internet of Things (IoT) are undeniable. IoT-enabled technologies collect data that impacts cost, productivity, compliance, and security.

Digital design data is a big data business. It requires secure management and storage, versions need to be stringently controlled, and teams need to access files readily so they can share that data with stakeholders.
For too long, however, designers, engineers, and CAD managers have relied on traditional document management systems, like network drives, to achieve this. While they do a great job with office documents, those same solutions don’t work well with today’s design files and models, for several reasons:

If your job involves capturing existing field conditions as part of the design and construction process, you’ll know it’s a tedious, manual, often analog and inaccurate process, which often leads to costly re-work.
Whether you’re renovating a building or involved in a large-scale infrastructure project, the process goes something like this:

As any surveyor or field engineer knows, capturing existing field conditions for an infrastructure project or building renovation is a tedious, manual, often analog, and inaccurate process – not to mention dangerous.
Renovations projects are a particular challenge since the infrastructure or building may be decades old and designed before the age of digital blueprints. You’re almost guaranteed to start a project using static 2D image documentation of existing conditions. Verifying and updating these manually is a lot of leg work.

Building information modeling (BIM) is poised for greater adoption by federal, state, and local government agencies. In Wisconsin, for example, publicly-funded projects over $5 million are required to incorporate BIM and 3D software from initial planning concepts to bidding documents and project closeout. Many DoTs, including MassDOT, FDOT, and CALTRANS are also embracing BIM for infrastructure projects.

It’s hard to imagine a world without digital. But as you look around you, much of the physical world was designed and constructed using traditional 2D blueprints and is yet to be captured in a digital format. This creates a challenge for AEC professionals to incorporate these as-built designs into re-build or renovation projects.
Traditional imaging techniques like photogrammetry aided in this process by allowing engineers to piece together photographs of as-built conditions and weave in GPS coordinates to create interactive 3D models, see below:
