Repairs involve the restoration of an asset that has broken, been damaged, or ceased functioning. In contrast, maintenance encompasses regular tasks and corrective or preventive measures performed on assets to avert damage and extend their lifespan.

For Example:
Broken Conveyor Belt Repair; Faulty Pump Replacement; and Machine Downtime Resolution. Preventive Maintenance – HVAC System; Predictive Maintenance – Vibration Analysis; Reliability-Centered Maintenance (RCM) – Aircraft Engine

INSTALLATION/ERECTION serves as the initial phase prior to commissioning, during which onsite project personnel, contractors, and vendors install brackets, frames, materials, and equipment within a building structure—whether internal or external. This process culminates in the establishment of a comprehensive Electrical, Fire, Mechanical, Controls, HVAC, Plumbing, and Drainage System, adhering to the specified design and construction drawings as well as design criteria.

COMMISSIONING involves the systematic application of industry-standard procedures to the installed systems. This phase encompasses planning, startup, testing, and operational implementation, facilitating an assessment of their performance and functionality. The goal is to ensure that these systems are effectively integrated, operate efficiently, and fulfill the overall commissioning and design specifications of the building, while also considering future maintenance and operational needs.
