BACHMAN HYUNDAI, JEFFERSONVILLE, IN

3S MEP  provided Mechanical, Electrical, and Plumbing design and drafting services  for the Bachman Hyundai.

We have performed HVAC design for a Hyundai  automotive dealership and service facility, including detailed heating and  cooling load calculations using HAP software. Based on the load analysis, several  zones were established, and gas-fired rooftop units (RTUs) were selected to  provide efficient heating and cooling throughout the building.

To enhance occupant comfort and temperature control,  Variable Air Volume (VAV) systems with reheat were incorporated within office  and administrative areas. The service department was designed with  High-Volume Low-Speed (HVLS) fans to improve air circulation, reduce temperature stratification, and increase occupant comfort within the large  open workspace.

Vehicle service areas were equipped with carbon  monoxide (CO) and nitrogen dioxide (NO₂) monitoring  systems interlocked with exhaust fans and outdoor air intake systems. This  ventilation control strategy helps maintain safe indoor air quality by  automatically introducing fresh air and exhausting contaminants when elevated  levels are detected.

Radiant gas heaters were provided within the service  department to deliver effective heating in high-bay areas. Due to exposed  ceiling conditions and overhead garage doors within the service reception  area, double-wall insulated ductwork was specified to prevent exterior condensation while maintaining a clean and professional appearance.

The HVAC design was developed in accordance with  Hyundai dealership design standards and incorporated a Trane® Concierge control system for centralised monitoring and operation. Dedicated sensors were provided for each RTU and VAV terminal to support efficient system performance, occupant comfort, and long-term operational reliability.

We have provided complete plumbing design services  for a Hyundai Service Station, including domestic water, sanitary waste, oil waste, and natural gas systems. The design incorporated oil interceptors for vehicle service areas, emergency eyewash stations for technician safety, and detailed sizing and selection of instantaneous water heaters and hot water storage tanks to meet facility demands. Engineering services included  hydraulic calculations and routing for domestic water piping, sanitary drainage, oil waste drainage, and natural gas distribution systems in  accordance with applicable codes and manufacturer requirements.

The project was developed using Autodesk Revit 2026, with a fully coordinated BIM model integrating architectural, structural, mechanical, and electrical disciplines. Extensive clash detection and  interdisciplinary coordination were performed to optimize equipment  locations, piping routes, maintenance access, and constructability. The resulting design delivered a code-compliant, efficient, and coordinated  plumbing infrastructure that supports both vehicle service operations and  occupant needs throughout the facility.

This project involved creating the electrical design for a critical emergency backup power system. The design includes detailed lighting layouts, power layouts, and outdoor site plans, along with all the  necessary panel and lighting schedules. At the heart of the system is a  special life-safety emergency generator that automatically turns on within 10  seconds if the main power fails. A compatible, certified Automatic Transfer Switch (ATS) was also placed in the layout, making sure it fits perfectly and  has enough open space around it for safety codes.

A key part of the lighting layout was setting up the  emergency lights, which are labeled as "Night Lights." Using  lighting and zoning schedules, these specific lights were connected directly  to the backup generator panel so they stay on during a power outage. Outside, the site layout manages the power for the large parking lot lights, which  stand 20 to 25 feet high. The plans carefully position these poles to account  for their massive concrete bases, which are 3 feet wide and go 5 feet into the  ground. The final project provides a clear, accurate design that ensures the  building stays safe and well-lit during an emergency.
