Commissioning of the Mechanical System encompasses a thorough evaluation of the design, installation, maintainability, and functionality of all major heating, cooling, and ventilation equipment. This process ensures that the systems perform as intended, operate efficiently, and support long-term operational reliability. Key areas of focus include, but are not limited to:

• Chilled Water and Hot Water Systems – Verification of system performance, distribution, controls, and integration with building operations.

• Smoke Control Systems – Validation of life safety features to ensure effective containment and evacuation capabilities under emergency conditions.

• Exhaust Systems – Critical assessments for specialized environments such as laboratories, kitchens, and cafeterias, ensuring safe and compliant removal of hazardous or contaminated air.

Through detailed commissioning, each component and system is rigorously tested to confirm that it meets both the project requirements and industry best practices.

Commissioning of the Building Automation Systems (BAS) is an essential part of validating the mechanical system. At 5D’s, we enhance this process by providing a more comprehensive level of BAS commissioning, which includes Point-to-Point Validation in addition to reviewing trend data. This thorough approach ensures a deeper verification of system performance.

Testing of the BAS typically includes verifying the following:

• Installation of the hardware and software

• Programming of the software

• Response of the components and equipment

• Accuracy & Effectiveness of the Sequence of Operation

• User interface for intuitiveness

• Training required and provided

Commissioning of Electrical Systems involves a comprehensive review to ensure proper installation, functionality, and operational performance of critical electrical infrastructure. At 5D’s, our validation process is thorough, focusing on verifying that each system component operates in accordance with the project design intent and meets applicable standards. Typical areas of focus include:

• Power Distribution Systems – Assessment of electrical panels, switchgear, transformers, and branch circuitry to confirm safe, efficient, and reliable power delivery throughout the facility.

• Uninterruptible Power Supply (UPS) Systems – Verification of backup power functionality, load transfer performance, and system integration to support critical operations without interruption.

• Lighting and Lighting Control Systems – Testing of illumination levels, control sequences, sensor functionality, and user interfaces to ensure optimal energy efficiency, occupant comfort, and operational flexibility.

Our detailed commissioning approach helps identify potential issues early, ensuring systems are fully optimized for long-term performance and reliability.

Commissioning of Plumbing Systems focuses on ensuring that all critical components are properly installed, fully functional, and aligned with the project’s design intent. At 5D’s, our plumbing commissioning process typically includes the verification of the following systems and equipment:

• Domestic Water Heaters – Confirming correct installation, capacity, and operational performance.

• Pumping Systems – Verifying flow rates, pressure settings, and overall system functionality for both potable and non-potable water services.

• Compressed Air Systems – Testing for system integrity, pressure regulation, and equipment responsiveness.

• End-Use Devices – Assessing fixtures and outlets to ensure proper functionality, accessibility, and user satisfaction.

5D’s commissioning approach ensures Plumbing Systems are optimized for reliability, efficiency, and long-term performance.

While 5D’s provides all the above commissioning in-house (meaning we do it ourselves), we are not certified to provide Building Envelope or Fire Protection Commissioning. Therefore, we have a very select group of peers we partner with for systems such as this.
