OuyOut creates a ReCap 3D scan in 1 day, saving months of data gathering work on a green building remodel

Overview

In the world of architecture, the balance between preserving historic buildings and creating sustainable structures can be tricky. OuyOut is a French firm committed to finding creative solutions to this problem, and readily tackles design challenges like this while growing its skills and capabilities.


Recently, the firm was tasked with designing an expansion building for CDER—an accounting and management firm in Champagne, France. The region well-known for sparkling wine has recently become well-known for its commitment to sustainability. The property CDER was hoping to expand into was built in 1963, and much of the structure was inefficient, aging, and visually unappealing.


Instead of demolishing the building, OuyOut chose to preserve some of the existing structure while designing an environmentally friendly renovation. This required careful and highly accurate planning. Thanks to the training given by Autodesk Partner Graitec, OuyOut created a 3D scan of the building in only one day that set the stage for a well-organized and highly creative design process.



Challenge

CDER recently wanted to expand its offices and had its sights set on a historic building from the 1960s. Located in Épernay—the “capital of Champagne” in France—the building was well-known as an eye-sore in the community. The initial strategy was to tear the building down and start from scratch. But the architects from OuyOut hired for the project decided to take a remodeling approach.


The Champagne region has been well-known for its sparkling wine for centuries. Starting in 2001, the region committed to sustainable production practices. Local wineries today treat 100 percent of all their wastewater and recover and reuse 90 percent of Champagne byproducts, as well as 100 percent of waste. The wineries have also reduced vine-protection product usage by 50 percent and lowered their per-bottle carbon footprint by 15 percent. Sustainable practices are quickly becoming an essential part of the Champagne region, and the CDER office expansion project wanted to align with these values. This is how OuyOut decided to pitch a renovation project, rather than an entirely new building.


By renovating the building, the project team could avoid materials waste from demolition as well as additional carbon released during a new construction project. But a renovation comes with the challenge of working with the existing structure. Though original design drawings were available in PDF format, these designs weren’t fully accurate. In an attempt to combat this, OuyOut used a geographic information system (GIS) to take measurements of the building. Though somewhat helpful, OuyOut was looking for measurements down to the finest millimeter within every part of the building—something GIS could not offer. The process of gathering relevant data using PDF's and GIS could take the team months. Without a high level of accuracy, the architects would be forced to make design assumptions that could lead to mistakes and time-consuming rework.




Solution

OuyOut was familiar with the Autodesk AEC family of products and planned to use Autodesk® BIM 360® Design and Autodesk® BIM 360® Docs to help create the design in a way that would later help inform the construction process. But the architects still needed a way to successfully scan the building and gain the detailed information needed to generate a flawless design. To address this, the team reached out to the Autodesk Services Marketplace in search of experts who could guide the team towards a better approach.


The Services Marketplace paired OuyOut with Autodesk Partner Graitec. The experts at Graitec worked directly with the architects, offering tailored advice that specifically addressed the needs of the project. OuyOut architects were offered training on Autodesk® ReCap™—a solution that helped with the scanning of the building, then converted 3D information to 2D drawings. The team also used Autodesk® Revit® to create building designs based on the 3D model. The entire training process was designed not only to drive project success, but to also drive success for OuyOut’s future endeavors.


With fully accurate model data collected through ReCap now setting the team up for success, the primary goal was to generate a design with optimal efficiency in mind. OuyOut integrated its Revit model with Autodesk® Insight to evaluate and optimize the model for energy efficiency throughout the design process.



Success

After reworking the design with PDF’s of old drawings and limited GIS scans for months, the 3D scan using ReCap took only one day to complete. The scan gave the OuyOut team the real and accurate dimensions of the building. This resulted in quicker decision making during subsequent design phases and improved communication to all stakeholders. Thanks to the faster workflows, construction is set to begin in early 2020.


Thanks to the working relationship with Autodesk Partner Graitec, OuyOut achieved its goals for creating a sustainable building design. Integrating Insight with the Revit model from the outset helped OuyOut assess the building façade’s energy efficiency and determine the effect of solar protection. The team achieved a design that insulates the building from the outside—offering protecting from the sun while capturing the thermal inertia of the concrete structure inside.


The architects at OuyOut gained skills that will help them design more environmentally-conscious buildings in the future. The Buildings Performance Institute reports that buildings in France contribute to 43 percent of energy consumption and a quarter of greenhouse-gas emissions. With more architects like OuyOut embracing green design solutions, this number could be significantly reduced in the future.


The original building was completed in 1963, and more than 50 years later the OuyOut architects have been able to preserve much of the original structure as part of the renovation. This reduced material waste due to demolition while limiting the need for new materials. It also means the Champagne region has the opportunity to preserve some of its history while making positive changes for the future. 


“We discovered that we previously had it all wrong. We are now able to work with the real dimensions so we can make decisions more quickly and better communicate with all our stakeholders.”
