For the Alice L. Walton School of Medicine, Ozark Green Roofs was tasked with installing an unprecedented rooftop landscape. Today, I want to share behind the scenes photos of our construction journey while building this green roof. We took plans, turned them into two virtual models, and executed the installation.
This journey was made possible by two forces that are essential to each other in today's modern construction world: Technology and People.
Technology and modeling changed our field execution:
📍 GPS Precision: Our crew used GPS rovers connected directly to the BIM model to place geofoam and soil profiles with exact field accuracy to meet the soil grades outlined in the plans.
📐 Topographic Slicing: Horizontal slices were cut every 6" through the model to define exact geometry of the geofoam layers.
🖥️ Visualization: Having a "pre-built" virtual model of the green roof was eye-opening. It took the guesswork out of the field and turned a high risk installation into a (mostly!) smooth and highly prepared process. It was critical that our geofoam installation was accurate, as it was the base for concrete to be poured on, and stone to be placed on. If our geofoam was placed at the wrong elevation, all subsequent layers of materials would also miss the required elevation.
The People:
🤓 Chloe and Kenneth Hiley at Catalpa Architects: This team managed our BIM Coordination, modeling, and all shop drawings. The huge lift of making our installation accurate was because of their attention to detail and experience with modeling.
👷♂️ JonesPlan: We subcontracted JonesPlan for labor for this project. Every one of their guys was dedicated to installing their materials correctly. They did it, with a smile, every single day.
🏗️ Crossland Construction: The people on this job from Crossland made us feel like a true team. The listened, supported, and guided us to the endzone.
⚡Superior Roofing: Dan, John, and the crew went to town installing the geofoam at what felt like lightning speed!
✍🌿OSD: The Landscape Architects at OSD didn't just draw plans and walk away. They were on site making sure their vision was accurately realized. While we "saw" the green roof virtually for months prior to the build, our team was in awe of the design after it was all said and done. The design of this rooftop landscape is truly badass.
🏦🏫 Polk Stanley Wilcox: None of this would have been possible without the BUILDING itself! PSW trusted us with the landscaping on top of their structure, and we loved every minute of working with their team!
