Techniques for managing the properties of concrete under stress.

FROM THE MARCH 2021 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

Watching a concrete pour and finishing is a fascinating but nerve-wracking process. All the planning, design, and research you have done as a designer comes down to a few unforgiving hours (if that) that determine whether your vision is fulfilled. Although it may feel out of your hands, there are things you can do as a designer to help ensure the concrete elements are successful.

Concrete cracks. That is in its nature. As concrete hydrates (the chemical process where compounds in the cement form bonds with water and harden the concrete), it shrinks. As it shrinks, cracks will form where the concrete is weakest. These cracks happen at the micro and macro (think visible) levels. (more…)

Trial and error yields a fluid sculpture for a public park.

FROM THE FEBRUARY 2021 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

In early 2020, the artist and landscape architect Falon Mihalic, ASLA, of Falon Land Studio was chosen to create Meander, a public art piece for Houston’s historic Market Square Park. The concrete and resin sculpture was to replace a beloved (but weathered) sculpture with something more modern and abstract, while also offering a place to sit for both adults and children and some additional light at night.

“Market Square Park is not a huge space, and it’s bound by things that I didn’t want to disturb,” says Mihalic, who is also the current chair of LAM’s Editorial Advisory Committee. “A previous iteration of Meander stretched into the paving, but they’re historic Freedmen’s Town pavers. So, we knocked out some planting beds to keep the historic elements intact.” (more…)

Parametric modeling aids the design for a complex paving pattern at a corporate campus.

FROM THE NOVEMBER 2020 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

When stepping off the city sidewalk and into the site of the Cummins headquarters building in Indianapolis, there’s an immediate sense of arrival into a distinct landscape. David A. Rubin, FASLA, the principal and lead designer at DAVID RUBIN Land Collective, says that the site is an expression of choice, with amenities for collaboration and contemplation, “allowing people the capacity to choose where to be most creative.” This could be in a cluster in the amphitheater, in movable seating, at an isolated bench, or around the long, Wi-Fi-enabled community table, dubbed the “High-Tech Harvest Table” by the design team.

Located in downtown Indianapolis, the Cummins DBU (shorthand for Cummins Inc.’s Distribution Business Unit headquarters) site spans a full city block. Along the site’s western edge is the Indianapolis Cultural Trail, a citywide bike and pedestrian path. Sweeps of vegetation planted atop elongated berms extend inward from here to guide circulation and, as Rubin describes it, to create a sense that the landscape was intentionally carved back to reveal the underlying hardscape. The main path, which zigzags east–west to connect the building entry and parking garage, widens at the heart of the site to become the central plaza. This multifunctional gathering space is framed by amphitheater seating and can accommodate performances and special events. Just adjacent is a communal work space, the Social Hub, where employees can bring their laptops and connect to power and Wi-Fi. A more secluded area, the Dell, offers benches for quieter work. These distinct subspaces are threaded together by a continuous two-toned paving pattern, creating a unified surface and visual identity for the site.

The eye-catching paving pattern, comprising alternating bands of light and dark concrete pavers, echoes the calibrated facade of the new Deborah Berke Partners building and is emblematic of a checkered flag, in reference to the Cummins diesel engine enterprise. The design team first explored concepts for the paving pattern through sketches and a 3-D model. According to Land Collective’s project manager, Henry Moll III, Affiliate ASLA, “Early studies included larger concepts of fading patterns and pixilation,” but ultimately they went with the more geometric and focused pattern. After selecting the two-toned scheme, the team turned to Grasshopper to further explore and refine the pattern’s scale and color distribution.

Grasshopper, which is now included in Rhino 6, is a visual scripting tool used for parametric modeling. In parametric modeling, design outcomes are created through the application of scripts, which establish and define relationships between components within given constraints. In a design workflow, a script can be used for ideation or for accomplishing a specific task. Moll describes Grasshopper as ideal for working with repetitive elements, because you can automate complex goals, which lends itself well to developing patterns. (more…)

Copenhagen’s stormwater detention roads are everything but.

FROM THE SEPTEMBER 2020 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

As part of its climate change and urban flood mitigation strategy, Copenhagen aims to build 300 stormwater management projects over the next 20 to 30 years. Among the projects are a series of detention roads, entire streets redesigned to convey and detain rainwater locally to relieve the existing storm sewer system. It’s an ambitious target that reflects the city’s understanding that investment in these projects is a way of managing greater long-term risk to city infrastructure while providing citizens with multifunctional spaces in the short term.

The Sankt Kjelds Square and Bryggervangen by SLA is a pilot of the detention road concept. Completed in 2019, it comprises the entirety of the 2,300-foot-long Bryggervangen road and Sankt Kjelds Square, the roundabout in the middle. “It’s quite a simple project,” says Bjørn Ginman, a project director at SLA, who says that the fundamental concept is about seeing water move through the site. Rain gardens lining the pedestrian rights-of-way receive rainwater from sidewalks and the roofs of adjacent residential buildings, while road runoff is directed into larger infiltration ponds at the roundabout and at intersections, though not before an in-ground diverter (one of the municipality’s first applications in a public road context) deals with the most polluted first flush.

A new series of stamps celebrates the diversity of public gardens.

 

Showcasing the diversity of American landscapes, past legacies of cultural stewardship, and the skills of generations of landscape architects, the U.S. Postal Service recently released the “American Gardens” stamp series, commemorating 10 landmark gardens across the nation. The gardens, many of them created by historically significant designers and makers, raise the visibility of landscape design in the American cultural realm by putting them into our hands and mailboxes every day, everywhere. The stamps were designed by Ethel Kessler and feature photos by Allen Rokach, a former director of photography at the New York Botanical Garden.

The stamps are a reminder of the vital role the outdoors offers during the COVID-19 quarantine, says U.S. Postal Service Director of Stamp Services Bill Gicker. “Time spent in nature, especially a beautiful and cared for garden landscape, can be very uplifting and rejuvenating—just what many people can use at this time,” he says.

A long-planned guide on construction documents for landscape architects is aimed at experienced and emerging professionals alike.

 

This week, ASLA’s Professional Practice Committee has released  The Landscape Architect’s Guidelines for Construction Contract Administration Services, which offers practitioners guidance to ensure that landscape projects are constructed in accordance with their contract documents. The guide is especially aimed at younger practitioners and emerging professionals starting their own firms, who may have less experience executing built work. “We decided that what we really needed was something that provided someone who is opening a business a basic understanding of where the risks and liabilities, as well as the responsibilities, lay,” says (William) Dwayne Adams Jr., FASLA, an Arizona-based landscape architect, and the editor of the guide.

The guide is arranged chronologically through the life of a project, and it presents the construction process from the perspective of not just landscape architects, but also the client and the contractor. Adams says that construction contract administration responsibilities often get delegated down to younger practitioners without much experience, and because of this, it’s necessary to provide greater context on what project partners are working through. “So what you have is a very parochial view of the world, that the landscape architect is pre-eminent in all the matters of site construction,” he says. But in reality, “you’re a team member, and you need to know what the other members of your team do.”

LETHAL GLASS LANDSCAPES

A proposed building and landscape ordinance could shape the future of bird-friendly design in Chicago.

FROM THE FEBRUARY 2020 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

On a mild Friday in early May, Ted Wolff took a personal day and drove to the Ballard Nature Center in Altamont, Illinois, to catch a glimpse of Lewis’s woodpecker, a nearly foot-long, pink- and white-breasted bird native to the western United States. Along with two other Chicago birders, Wolff, the garrulous, white-bearded principal of Wolff Landscape Architecture, was on a “twitch,” an English expression for pursuing a bird in a geographic area where it is rarely seen.

Early that morning, an Illinois Rare Bird Alert reported that the woodpecker—named after the explorer Meriwether Lewis, who first saw the bird on his expedition with William Clark—had been seen at the nature center. It was reason enough for Wolff to clear his docket. Before long, the three birders were driving south to be among the first people to see the bird in Illinois, outside its historic range.

When they entered the nature center’s indoor viewing area, the woodpecker was already perched on a platform feeder—a “walk-up,” in birder’s parlance—eating shelled peanuts in front of a one-way reflective plate glass window. They watched it peck at the platform for several minutes, then fly to a hackberry with a peanut wedged in its bill, pausing before circling back to the feeder.

“At some point, though,” Wolff told me later in his office on the sixth floor of the Old Republic Building on North Michigan Avenue, “it flies over toward the feeder and overshoots and flies into the window. I think it sees its own reflection and it sort of pulls up and touches the window lightly and is able to fly off.”

Many birds are not so lucky. Ornithologists estimate that up to a billion birds, often migratory birds listed as species of conservation concern, die in building collisions in the United States annually—collisions that Wolff says are largely preventable, and deaths that warrant a stronger response from landscape architects as advocates for bird-friendly design.
