Larson Design Group (LDG) worked with Willow Run Foods and Ryder trucks to prepare permit and bid documents for modifying their existing repair garage for CNG code compliance.

The repair garage, owned by Willow Run Foods and operated by Ryder, was designed to meet code compliance for CNG powered vehicles. LDG designed a methane detection system interlocked with exhaust fans, garage doors, and infrared heaters. The ventilation, heating, and electrical systems were designed to meet NFPA 30A and International Fire Code.

LDG prepared contractural bid documents and facilitated bidding out the mechanical and electrical construction work.
