Key Project Case Studies

The Clement Canopy
Singapore
A project in Singapore that exemplifies mandated modular construction through Prefabricated Prefinished Volumetric Construction (PPVC)

Methods Used:

Emphasized early stakeholder coordination and planning

I5 Relevance:

Aligns with I5's focus on rigorous process planning and stage-gate reviews

Dubai Municipality Pilot 6-Floor Project
Dubai, UAE
Dubai Municipality issued its first modular construction license for this pilot project

Methods Used:

Modular construction approach

I5 Relevance:

Demonstrates the UAE's openness to innovation in construction, aligning with the I5 Model's focus on off-site construction

Sutter Medical Center Castro Valley
California, USA
An IPD project case study

Methods Used:

Integrated Project Delivery principles, fostering strong collaboration

I5 Relevance:

The I5 Model incorporates IPD principles, which have shown projects are 3 times more likely to complete ahead of schedule and 2.5 times more likely to complete under budget
