The Construction Consultancy That Thinks Differently
FIVEi is a strategic advisory and quantity surveying consultancy built around one belief:
“Construction doesn’t fail because of process. It fails because the critical issue gets missed.”
We don’t just see the budget or the programme, we see the relationships, pressure points, stakeholder incentives, and the one overlooked detail that can shift the outcome.
What Sets Us Apart
Cost Effective
Solutions
We've worked on all sides of the table; as developers, contractors, consultants and suppliers.
MMC
Expertise
We understand modern methods of construction (MMC) and how to apply them commercially, practically, and contractually.
Unfiltered
Honesty
We'll tell you the truth, not what you want to hear, and we'll help you act on it.
