Site Supervision for Manufacturing Plant Expansion: Managing Quality, Cost and Execution

Contractor Coordination: Managing Interfaces, Not Just Contractors

Manufacturing expansion rarely has one contractor doing everything.

Civil, structural, MEP, utility, equipment and specialist contractors may each control different parts of the project.

The supervision function should therefore create clear interfaces between them.

For every critical work package, the team should know:

• Who is responsible?
• Which drawing governs the work?
• What needs to happen first?
• What information is required from another contractor?
• What inspection is required before handover?
• Who accepts the completed work?

This is particularly important around equipment foundations, utility corridors, cable trenches, drainage, HVAC areas and service penetrations.

Many execution problems occur not because one contractor cannot perform the work, but because two contractors assumed the other would manage the interface.

Brownfield Expansion Requires a Different Supervision Mindset

A greenfield project gives the construction team a relatively clean environment. Brownfield expansion does not.

Construction may occur beside operating production lines, existing electrical systems, utility networks, warehouses and employee movement routes.

Supervision therefore needs additional controls for:
