The addition for American Standard  Circuits Inc. consists of a 20,000 sq. ft. warehouse facility dedicated to  the manufacturing of circuit boards. The mechanical, electrical, and plumbing  systems were designed by 3S MEP+S, providing a fully coordinated and  efficient building systems solution tailored to the operational requirements  of the facility.

The Mechanical team performed  detailed heating afnd cooling load calculations for the PCB manufacturing  facility to determine the HVAC requirements for the various production,  testing, office, and support spaces. The facility included layup rooms, layup  preparation and dipping areas, quality control spaces, electric testing  departments, multilayer manufacturing areas, maintenance shops, offices,  storage rooms, and the plating floor.

Rooftop units (RTUs) were selected  and sized to provide temperature control, ventilation, and occupant comfort  throughout the office and manufacturing areas. Air distribution systems were  carefully designed to provide balanced airflow while accommodating equipment  layouts and process requirements. Ventilation rates were established in  accordance with applicable mechanical codes and industry standards to  maintain indoor air quality and support manufacturing operations.

A significant portion of the  mechanical design focused on the plating floor, where process exhaust  requirements necessitated the installation of a dedicated make-up air unit  (MAU). The MAU was designed to provide conditioned outdoor air during both  summer and winter operating conditions, ensuring proper building pressure  control and replacement of exhausted air. Roof-mounted exhaust fans were  designed and sized to remove process-generated contaminants and comply with  code-required exhaust rates. The mechanical systems were coordinated with  architectural, structural, and process equipment layouts to ensure efficient  operation, serviceability, and constructability.

The Plumbing team designed the  domestic water, sanitary waste, and natural gas systems using the existing  building utility services. Domestic water and sanitary piping were provided  for the new restrooms and support areas in accordance with applicable plumbing  codes.

To connect the new restroom  addition to the existing sanitary system, a sewage ejector pump was designed  to discharge wastewater to the existing sanitary manhole. This approach  reduced the complexity of routing new sanitary piping through the existing building  and minimized construction impacts.

The natural gas piping system was  also designed to serve gas-fired mechanical equipment. Overall, the plumbing  design provided a simple, efficient, and cost-effective solution while  utilizing the existing utility infrastructure.

A detailed  electrical design was developed for the project, focusing on branch circuit  distribution, power layouts, and emergency egress lighting systems. Branch  circuits were designed and routed to serve building loads while complying  with applicable National Electrical Code (NEC) requirements. Emergency egress  lighting layouts were prepared in accordance with International Building Code  (IBC) requirements to provide safe means of egress during emergency conditions.

Coordination  with architectural, mechanical, plumbing, and structural disciplines was  performed throughout the design process to ensure proper routing of electrical systems, avoid clashes, and maintain overall project  constructability. The electrical design was developed to provide a safe,  reliable, and code-compliant installation while meeting the operational  requirements of the facility.

With all  3S MEP+S projects, a primary focus is on 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+S actively engage with all stakeholders to identify potential conflicts and optimize the overall system layout. Our  teams are exceptionally proficient at harmonizing essential building elements  for successful outcomes.
