Civil and Structural Engineering Key to Creating a Massive Green Roof for Costco

By W. Lee Shoemaker, Ph.D., PE, F. SEI, Director of Research and Engineering, Metal Building Manufacturers Association

In Mexico City, on top of Costco’s metal building warehouse, parking garage and loading dock rests a ½-million-square-foot roof of sports parks and recreation. On the way to pick up some macaroni and cheese, fish sticks, and paper towels at Costco Warehouse in Santa Fe, Mexico City, one might initially have a hard time finding the store. That’s because the 144,522 square feet warehouse is camouflaged underneath what is arguably the largest green roof to ever cover a retail building.

A metal building system houses the warehouse portion of the complex, delivering multiple benefits in sustainability, cost savings, flexibility, durability and speed to market. Credit: Omar Franco
