Definition:
Rules that dictate task sequences due to physical, contractual, or regulatory constraints (e.g., environmental restrictions or safety requirements).
Key Components:
- Physical Constraints: Tasks that must occur in a set sequence due to construction or operational requirements.
- Contractual Constraints: Agreements that define specific work sequences.
- Regulatory Constraints: Compliance with legal and safety requirements.
Use Cases/Industries:
- Construction: Ensuring structural foundations are completed before vertical construction begins.
- Energy Sector: Sequencing environmental impact assessments before construction permits.
- Manufacturing: Complying with safety regulations for hazardous material handling.
Advantages:
- Ensures logical work sequencing.
- Prevents violations of safety and regulatory rules.
- Improves project coordination and compliance.
Challenges:
- Can create bottlenecks if not planned properly.
- May introduce delays if approvals take longer than expected.
