Prefabrication, preassembly, modularization, and offsite fabrication (PPMOF) offer potential benefits that are more important than ever in today’s markets. Owners want better facilities faster, at the lowest possible cost, and always safer. For the right project conditions, PPMOF can help achieve the owners’ goals.

PPMOF also can help project teams meet the challenges of demanding schedules, adverse site conditions, and limited availability of skilled labor. Using these methods, however, requires careful consideration of their implications for engineering, transportation, coordination, and project organization.

Managers considering PPMOF need a systematic method to evaluate the potential benefits and barriers to using these special methods on their projects. CII formed the PPMOF Project Team to update and extend prior CII efforts and to help improve project performance through use of PPMOF. The project team chose to focus on identifying the requirements for effective use of PPMOF on industrial projects, and then developed a framework to use as a decision aid about possible use of these methods. The framework includes a decision-timing map, a flow chart, tools for strategic analysis, and suggestions for a more detailed tactical analysis.

The results described in this summary build on and extend prior CII work on this subject, based on industry drivers that strongly favor increased use of PPMOF. The purpose is to present the benefits of PPMOF and motivate decision makers and project teams to fully consider PPMOF using the decision framework. The successful CII Project Definition Rating Index (PDRI) tool for analysis of project readiness has improved project performance; the PPMOF analysis framework can bring similar benefits in evaluating possible use of these special methods.
