The pros and cons of adopting BIM have oversized impacts on smaller firms.

FROM THE JULY 2021 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

Small landscape architecture firms face a unique set of challenges when deciding whether to adopt Building Information Modeling, also known as BIM.

In this article, we define small firms as those with fewer than 10 employees, including sole practitioners. Each firm we interviewed falls into this category. For a small firm, the decision about whether to adopt BIM is fraught with questions about cost, loss of productive work time, employee training, and even impacts to the firm’s design culture. Few examples of successful BIM implementation in small firms have been documented, contributing to a fear that some of those firms are being left behind as the technology advances. Yet BIM adoption in small design firms is not as uncommon as it may seem. A 2018 survey by ASLA’s Digital Technology Professional Practice Network surveyed 480 ASLA members on their digital technology usage. Of the 27.3 percent of respondents who identified information modeling or BIM as important to their work, more than half were from firms of 10 or fewer employees. Of the 19.8 percent of survey respondents who identified information modeling or BIM as something they were interested in pursuing, more than half were again from firms of 10 or fewer employees.

Cornelia Hahn Oberlander, 1921–2021 (In Memoriam)
Remembering the life and career of the celebrated landscape architect.

On the Safe Side (Maintenance)
A landscape laborer is far more likely to get hurt on the job than a landscape architect. Some firms are starting to take a harder look at their role in reducing worker risk.

Features

Small Firm, Big Leap
BIM training and software costs are a significant debit for small design firms. As principals weigh the pros and cons of adoption, the competitive cost of not being “in the model” is part of the equation.

Mine, Ours
As Western nations look to a postcoal future, the Lausitz region of Germany eyes turning its defunct mining pits into lakes and its industrial scrapes into tourist attractions. For now,
the contradictions are delightfully instructive.

Print to Scale (Tech)
A low-budget student project meets new 3-D printing technology, and an award-winning garden
is the result.

        Room to Lead (Advocacy)
The National Association of Minority Landscape Architects formed in a moment of recognition. Now it is using its platform to reach out to students.

FEATURES

    Alternate Ending
Silver Lake Reservoir in Los Angeles was once a gathering place, but when it was decommissioned, the future went hazy. Navigating a vocal public process, Hargreaves Jones and the local firm Chee Salette honed a jumble of ideas into a plan for people and wildlife.

Whose Eyes on the Street?
Design strategies meant to prioritize safety in public housing often increase surveillance and overpolicing instead. A new program for New York City Housing Authority communities returns the keys to the people who live there.

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…)

A high-tech greenhouse developer argues that preserving the agricultural landscape
requires a sustainable, scalable start-up.

FROM THE OCTOBER 2020 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

One of the first things visitors will notice inside the sprawling AppHarvest complex—a 60-acre, 2.76-million-square-foot, 30-foot-high greenhouse in Morehead, Kentucky—is the blinding, almost antiseptic whiteness. A forest of tomato plants, green tendrils reaching up from nutrient-rich charcoal beds toward the glass roof, will soon be arranged in rows that stretch nearly a mile end to end. Walls, gutters, and flooring, all coated in white to reflect the sunlight, give the appearance of a soundstage.

“It’s just awe-inspiringly massive,” says Kentucky native Jonathan Webb, the company’s founder, about the experience of standing inside a space the size of 30 Tesla Gigafactories. Seedlings have already been planted, and by the end of the year, AppHarvest will be shipping the first of what it hopes will be an annual haul of 45 million pounds of fresh, Kentucky-grown tomatoes to grocers including Kroger, Walmart, and Costco. “We’re trying to use technology to align with nature and put nature first,” Webb says.

As its name suggests, AppHarvest views farming and food through a start-up lens. For Webb, who has a background in the solar industry, the central argument is sustainability. Tomatoes are grown year-round in a climate-controlled, chemical-free greenhouse using hydroponics, robotics, more banks of LED lights than a ballpark, and two species of wasps for natural pest control, resulting in significantly more produce per acre. Strategically placing one of North America’s largest greenhouses within a day’s drive of 70 percent of the U.S. population means less time between harvest and consumption, ideally resulting in a tastier tomato and less trucking emissions. Nearly $2 billion worth of tomatoes are currently shipped into the United States annually from farms and greenhouses in Mexico.

Webb argues he needs to go big to fight the dystopian farming practices of Big Agriculture, which run ever-larger industrialized operations that emit noxious levels of animal waste and fertilizers. Animals raised on huge CAFOs (concentrated animal feed operations), for instance, live in crowded misery, amid complexes that stain the landscape with so much ammonia and nitrogen, hydrogen sulfide, and methane that children nearby developed elevated levels of asthma. Artificial structures of glass and steel the size of airport terminals can free up the land by concentrating production. It’s a pragmatic strain of tech utopianism that asks if the sacrifice of a small portion of the landscape can serve the greater good. (more…)

When designers need to calculate the environmental cost of projects, a new tech tool crunches the numbers.

FROM THE OCTOBER 2020 ISSUE OF LANDSCAPE ARCHITECTURE MAGAZINE.

 

For the new Frederick Douglass Memorial Bridge project in Washington, D.C., landscape architects at AECOM made sure that the bridge’s adjacent 80-acre waterfront park would provide many environmental benefits: bioswales and rain gardens for treating stormwater, pollinator meadows, and extensive tree cover to reduce the urban heat island effect. But when they did a rough estimate of how long it would take for the carbon dioxide absorbed by the plantings to cancel out the carbon dioxide emitted from producing asphalt and concrete paving and from maintenance, they got a surprisingly high number: 39 years. Two other completed projects they investigated took even longer to become carbon neutral: 346 and 154 years. “It was pretty interesting—we had no idea we were that far off,” says Ignacio Bunster-Ossa, FASLA, the vice president of landscape architecture and urbanism for the Americas at AECOM.

These calculations can be done painstakingly by hand, but Bunster-Ossa’s group was able to get these results by using Pathfinder, a new carbon calculator and design tool designed specifically for landscape architects. The app’s developer, Pamela Conrad, ASLA, a principal at San Francisco-based CMG Landscape Architecture, has spent the past four years thinking about the carbon footprint of landscape projects. “A landscape looks green, so we assume that it’s good and that we do good things,” says Conrad. “But it has a unique carbon impact that is hidden to the eye—it’s only when we measure that we can fully understand this complex formula.” (more…)
