MEP & Fire Protection design for San Lucy District Fire & Police Department project in Gila Bend, AZ

S3DA Design is providing comprehensive MEP and fire protection engineering services for the San Lucy District Fire & Police Department project in Gila Bend, Arizona. The scope supports the facility’s essential electrical, HVAC, plumbing, and fire sprinkler systems through a coordinated engineering approach. 

S3DA’s Scope 

Electrical Engineering 

• Designed the incoming electrical service from the utility transformer to the main distribution board. 

• Developed the complete electrical power distribution system. 

• Designed interior lighting, exterior façade lighting, exit signs, and associated lighting controls. 

• Provided outlet rough-in layouts. 

• Coordinated electrical power requirements for HVAC systems and miscellaneous equipment. 

HVAC Engineering 

• Designed a new HVAC system for the facility. 

• Performed heating and cooling load calculations. 

• Developed HVAC air distribution plans and air-balancing requirements. 

• Designed restroom exhaust systems. 

• Prepared mechanical equipment schedules. 

Plumbing Engineering 

• Designed new domestic water, water-heating, sanitary, and vent systems based on the proposed building layout. 

• Designed condensate collection systems for mechanical equipment. 

• Selected water-heating equipment and prepared the corresponding schedules. 

• Developed plumbing isometric drawings. 

• Prepared plumbing equipment schedules, details, and system documentation. 

Fire Protection Engineering 

• Developed the fire sprinkler system plan. 

• Prepared the fire protection zoning plan. 

• Coordinated fire protection requirements with the building’s mechanical, electrical, and plumbing systems. 

Key Challenges & Solutions 

Public safety facilities depend on reliable building systems that must operate efficiently while supporting the specialized needs of fire and police personnel. S3DA’s engineering team coordinated the electrical, HVAC, plumbing, and fire protection systems as one integrated design package, helping reduce conflicts between disciplines and improving the overall constructability of the project. 

This coordinated approach reflects S3DA Design’s goal of serving as a single source of responsibility, reducing the burden of coordinating multiple engineering consultants while helping projects meet budget and scheduling requirements. 

The Result 

The project delivers a coordinated MEP and fire protection design package intended to support permitting, construction coordination, occupant comfort, operational reliability, and life-safety requirements for the San Lucy District Fire & Police Department facility.
