To expand a running plant without stopping production, locate underground services before digging, group tie-ins into planned shutdowns agreed with operations, plan every heavy lift near live equipment, work inside the plant’s permit system, separate construction from operating areas, and use one contractor for all trades so the sequence stays controlled.
1. Map what is underground
Old plants have pipes and cables nobody has drawn. Locate them before any excavation; hand-dig near live services.
2. Plan tie-ins as a group
Connections to live systems should be grouped into planned shutdowns, agreed with operations, instead of stopping the plant again and again.
3. Plan every heavy lift
Crane positions, ground bearing, reach and exclusion zones, planned before the lift day, especially near live equipment.
4. Work inside the permit system
Hot work, excavation, height and confined-space permits come from the plant. Sequence them with the operations team.
5. Keep construction separate
Barricades, access routes and housekeeping keep construction away from operating areas.
6. One contractor for all trades
In a tight running plant, several contractors block each other. One team plans the sequence and owns the result.
