Bringing BIM to Life in the Outdoors: Alejandro Masferrer Gatica on the Evolution of Landscape Architecture

Building Information Modeling, or BIM, has revolutionized architectural design and project management, but it’s not just for buildings anymore. Landscape architecture is taking bold strides forward with BIM, redefining how we envision, plan, and bring outdoor spaces to life. Alejandro Gatica, Principal BIM Manager at Gillespies, is leading the charge, proving that BIM is just as relevant to the land around the building as it is to the building itself. Here, Alejandro shares how Gillespies is integrating BIM into landscape architecture and what this could mean for the future of outdoor design.

Why BIM in Landscape Architecture?

BIM has been a staple in traditional architecture for years, streamlining the design and construction process with precision and data-driven insights. However, applying BIM to landscapes adds complexity due to unique challenges such as irregular topographies, changing gradients, and the ever-present element of nature. As Alejandro explains, unlike a structured building, landscapes are in constant flux and need a more adaptable BIM approach. From planning intricate planting beds to coordinating public park systems, BIM allows landscape architects to plan and visualize in new and more effective ways.

“Applying BIM in landscape architecture is a challenge worth taking on,” Alejandro explains. “It brings coordination and accuracy that is difficult to achieve with traditional tools. The level of detail we can accomplish allows us to manage planting schedules, drainage systems, and even compliance with regional standards in ways that were previously impossible.”

The Real Benefits of BIM in Landscape Architecture

The advantages of BIM in landscape architecture go beyond the design phase, impacting every stage from concept to completion. With BIM, landscape architects can visualize every slope, path, and planting with a higher level of detail, identifying issues early on and avoiding costly mistakes. It’s particularly useful for creating immersive presentations, allowing designers and stakeholders to “walk through” a landscape before it’s even built. Alejandro notes that this approach not only improves the efficiency of project delivery but also enhances communication with clients.

One of Alejandro’s notable projects at Gillespies was a rooftop park in London, which required careful coordination with architects to integrate structural and landscape elements seamlessly. Through BIM, Alejandro’s team could simulate how each component would interact with the underlying structure, from soil depths to water drainage systems. This level of precision has led to more resilient and sustainable designs that can adapt to the surrounding environment.

Breaking Down Barriers Between Architecture and Landscape Design

In many architectural projects, the landscape has often been seen as a finishing touch, a “green garnish” added once the core design is in place. BIM is reshaping this perception, enabling landscape architects to be part of the process from day one. With BIM, landscape architects work alongside architects and engineers, making real-time adjustments that integrate landscape and structural elements seamlessly. For Alejandro, this collaborative environment is what makes BIM truly transformative.

Alejandro’s role as a bridge between architecture and landscape is evident in his work on large-scale projects in Qatar, where Gillespies has managed everything from streetscapes to large canals. The firm’s ability to work directly within a shared BIM model means fewer design conflicts and faster, smoother workflows.

“BIM is helping us break down traditional silos. Landscape, architecture, and engineering are now part of one continuous conversation, which results in more holistic and cohesive designs,” Alejandro says.

The Role of Visualization and Virtual Reality

Visualization technology like Lumion and Twinmotion is helping Alejandro bring landscape designs to life in ways that were unimaginable a few years ago. These tools allow the team to create detailed, real-time renders, which can be viewed in VR. Walking through a virtual model provides invaluable insights and helps clients understand scale, lighting, and flow. As Alejandro describes, it’s more than just a presentation tool; it’s a powerful method for refining design.

“Visualizing a landscape in 3D and VR allows us to make smarter decisions early on. We can spot level inconsistencies or see if a space feels too narrow before any physical work begins,” Alejandro explains.

By bringing stakeholders into a virtual landscape, landscape architects can convey their vision more accurately, avoiding the common misunderstandings that arise from flat drawings. Alejandro’s team also uses VR to detect design issues, saving time and resources during the actual build.

A Glimpse into the Future: AI and BIM in Landscape Architecture

Artificial Intelligence (AI) is a topic on everyone’s mind, and BIM is no exception. While AI is still in its early stages within landscape architecture, Alejandro sees promising applications. Tools like MidJourney and ChatGPT are already aiding the team in idea generation and content drafting. However, the real potential lies in AI’s ability to enhance data-driven decisions and improve project accuracy.

“AI won’t replace the designer, but it will replace tedious tasks and speed up the design process,” Alejandro says. He believes AI has the potential to further optimize the workflow, possibly allowing landscape architects to generate data-based designs with a few clicks. For instance, an AI could recommend the best plant species for a given soil type or predict erosion patterns based on environmental data.

As these technologies mature, Alejandro sees a future where AI and BIM work together seamlessly, leading to even more responsive and adaptive landscape designs.

Advice for Landscape Architects Diving into BIM

For those entering the field or looking to specialize, Alejandro offers some valuable advice: start by building your software skills, particularly in Revit and visualization tools. While certification courses are valuable, much of what Alejandro learned came from exploring tools on his own and seeking out online resources. Staying curious and open to new technologies is key, as BIM and AI continue to evolve.

“Don’t be afraid to dive in,” Alejandro advises. “The best way to learn is by doing. Start with small projects, play around with the tools, and push yourself to experiment with new software.”

For landscape architects ready to embrace the future, BIM offers exciting possibilities. Alejandro’s work at Gillespies is proof that integrating landscapes into the digital realm of BIM doesn’t just improve efficiency—it elevates the artistry of landscape design, paving the way for more resilient, connected, and beautiful outdoor spaces.
