An extensive MEP project at this Hyundai dealership involved complex design considerations from 3S MEP + Structural in mechanical, electrical and plumbing areas.

In the service department, the design of the mechanical systems prioritized adequate ventilation to control fumes and maintain air quality. A high-efficiency HVAC system with proper filters and exhaust systems.

The garage’s mechanical system design incorporated sensors and an exhaust fan to mitigate CO and NOx gases, aligning with IMC code regulations. This setup actively monitors air quality, quickly detecting harmful gases and activating the fan to expel them.

The mechanical team made a comprehensive heat-load calculation to determine the heating and cooling requirements and designed the HVAC ductwork layout to efficiently distribute conditioned air throughout the building. A rooftop unit with economizer systems was selected to provide optimal heating, cooling, and ventilation.

Two main electrical challenges were accurately determining the load for the entire project and implementing lighting controls for multiple zones. Our experience in previous projects with similar dealerships was valuable in meeting these challenges.

Another issue was finding suitable space to accommodate two step-down transformers and all the panelboards within the designated electrical room. A separate electrical room was necessary for the power service entry point and meter.

The locations for EV chargers in the service department and parking areas were selected to align with strict Hyundai standards. Power layout for light fixtures on various multidisplays, directional signage, and lighting clouds were also designed to meet Hyundai standards.

Electrical design included a basic fire alarm system.

The main challenge in the plumbing systems was identifying a suitable booster pump that could efficiently address the pressure requirements of the building. We also developed a gas piping system to facilitate the safe distribution of gas within the building.

The plumbing team designed sanitary waste, water, and stormwater drainage systems. The team selected the oil interceptor, water heater, and other equipment according to code requirements.

The team also selected plumbing fixtures according to Hyundai standards.

With all 3S MEP projects, a primary focus is integrating MEP and structural designs with the construction and architectural partners and the end-users to minimize the need for design adjustments or revisions during the construction process. Design teams from 3S MEP actively engage with all stakeholders to identify potential conflicts and optimize overall system layout. Our teams are exceptionally proficient at harmonizing essential building elements for successful outcomes.
