5 Critical Mistakes That Sabotage Project Handover (And How to Avoid Them)

After 25 years and 3,500+ projects, we have seen every handover mistake imaginable. The good news? They are all preventable. Here are five of the most critical project handover mistakes — and how to avoid them.

Mistake #1: No AIR Before Tender

The Problem:
Projects define Asset Information Requirements after contractors are already appointed. Contractors did not price for comprehensive information delivery. They resist what they perceive as “new” requirements.

The Consequence:
Incomplete information, contractor disputes, and post-handover validation nightmares.

The Solution:
Develop detailed AIR during design. Include it in tender documents. Make it contractual. Contractors price it. Project teams deliver it.

Mistake #2: Vague LOIN Definitions

The Problem:
Requirements like “provide complete asset information” or “deliver comprehensive O&M manuals” sound clear but mean nothing specific.

The Consequence:
Contractors interpret requirements differently. Deliverables are inconsistent. Information gaps are inevitable.

The Solution:
Define LOIN precisely for each asset type. Specify exactly what information is needed, in what format, and to what level of detail. Leave no room for interpretation.

Mistake #3: Late AIM Implementation

The Problem:
Waiting until construction is underway — or nearly complete — to implement the Asset Information Model.

The Consequence:
Design-phase information is lost. Contractors resist retrofitting information capture. Validation becomes a post-handover exercise.

The Solution:
Implement AIM during the design phase. Capture information progressively. Validate continuously. Deliver complete data at handover.

Mistake #4: No PHCC Engagement

The Problem:
Assuming contractors will deliver complete, validated information without independent quality assurance.

The Consequence:
Information gaps are discovered at handover — when it is too late to fix them efficiently.

The Solution:
Engage Project Handover Compliance Consultants (PHCC) well before completion. Independent QA ensures information completeness and quality before handover. If you want more detail on the role, see our overview of information management consultants.

Mistake #5: Assuming BIM = FM-Ready

The Problem:
Believing that BIM compliance automatically delivers operational readiness.

The Consequence:
Well-developed 3D models that do not contain the structured asset information facilities management teams need to operate the building.

The Solution:
Understand the distinction between PIM (construction) and AIM (operations). Implement both. Ensure BIM deliverables include FM-ready asset data.

The Pattern

Notice the pattern? All five project handover mistakes stem from the same root cause: treating handover as an end-of-project event rather than a process that starts at design.

The Mindset Shift

Successful handover requires a fundamental shift in thinking.

Old mindset:
“We’ll compile handover information when construction is complete.”

New mindset:
“We’ll capture and validate information progressively throughout the project lifecycle.”

This shift transforms handover from a painful scramble into a controlled, predictable transition.

The Question for Your Project

How many of these five mistakes is your project making? One? Three? All five?

This is a pattern we see repeatedly across projects.
The good news is that it is never too late to start fixing them. But the earlier you start, the better your outcomes.
