Seymour, Indiana

MNA was the Lead Architectural and MEP Designer for the facility expansion of an existing engine plant. The project included upgraded utility systems to serve the expansion as well as the existing facility.  The existing facility remained in operation; therefore the design, sequencing, and phasing of the utility upgrades was critical to minimize down-time.  The expansion included eleven (11) test cells for the development and production testing of high-horsepower internal combustion engines. The project was constructed over three (3) phases with a facility project cost of approximately $125 million.  In addition to this project, MNA’s roles included overall Master Planning and design of a separate 80,000 sq ft Office Building supporting this facility.

SUSTAINABILITY: Design options related to sustainability and energy savings were evaluated through a NPV process.  The project chose to include multiple regenerative dynos, converting engine power into electrical power. MNA’s design included integrating the dyno into the electrical power system for use within the plant or distribution back to the utility company. In addition, provisions were made for a future heat recovery system, reclaiming energy rejected to the process water system.

BIM:  MNA was the administrator of Revit Models and associated coordination efforts with other consultants.  All facility components, process, engines, and material handling equipment were modeled.  The models were integrated into Navisworks for clash detection.  MNA led multiple coordination meetings with all parties through the course of the project.

MAINTENANCE/OPERATIONAL DESIGN: The BIM model was used as a tool to allow the Users to visually comprehend the facility throughout the design process. The collaboration that resulted in the use of this tool improved operational and maintenance features in the facility.  These features included providing access to major components, material handling pathways, and location of life safety devices such as fall protection systems and gates.
