Definition:
A comparison between traditional on-site (stick-built) construction and off-site modular fabrication to determine the best execution approach for industrial projects.
Key Components:
- Stick-Built Construction:
- On-site assembly of materials and components.
- Greater flexibility for design changes.
- Higher dependency on skilled labor and weather conditions.
- Modular Construction:
- Off-site prefabrication and transport for installation.
- Requires advanced planning and strict design finalization.
- Reduces construction time, labor costs, and safety risks.
Use Cases/Industries:
- Oil & Gas: Comparing pipeline compressor stations built on-site vs. prefabricated skids.
- Infrastructure: Evaluating modular bridges vs. cast-in-place construction.
- Power Plants: Determining feasibility of prefabricated substation modules.
Advantages of Modular:
- Shortens Project Timelines: Work is completed in parallel with site preparation.
- Improves Quality Control: Modules are built under controlled factory conditions.
- Enhances Safety: Less exposure to hazardous conditions for field workers.
Challenges of Modular:
- Transport & Handling Risks: Oversized loads require specialized logistics planning.
- Upfront Design Rigidity: Changes are costly once fabrication begins.

Example:
A refinery upgrade project transitioned from stick-built to modular construction, cutting field labor costs by 30% while maintaining quality standards.
