Relevant project experience can provide valuable insight into a contractor’s ability to anticipate and manage technical challenges.
2. Safety Management and Qualified Supervision
Industrial mechanical construction can involve significant hazards, including heavy equipment, elevated work, hazardous energy, confined spaces, and lifting operations.
The specific risks depend on the project scope and facility environment.
Contractors should demonstrate established safety procedures, qualified supervision, and an understanding of applicable facility requirements.
Important considerations include:
- Site-specific hazard assessments
- Appropriate worker training
- Equipment isolation and lockout/tagout coordination
- Lifting and rigging plans
- Hot work procedures
- Confined space entry requirements
- Daily safety communication
Safety should be integrated into construction planning and execution rather than treated as a separate administrative requirement.
3. Technical Capabilities and Construction Coordination
Industrial mechanical projects frequently involve several interconnected systems.
For example, replacing a large storage tank may require coordination between equipment suppliers, concrete crews, rigging personnel, pipefitters, welders, and facility operations.
A qualified contractor should understand how these activities affect one another.
Effective coordination helps identify potential installation conflicts and ensures that construction activities are completed in the correct sequence.
4. Experience Working in Active Industrial Facilities
Many industrial mechanical projects must be performed while other parts of the facility remain operational.
