Why BIM handovers fail and how to avoid them
A client-side guide to delivering information that estates and facilities teams can actually use
Overview
BIM handovers rarely fail on the day information is handed over. More often, they fail months earlier when information requirements are poorly defined, information quality is not actively managed throughout the project, or the operational needs of the organisation are never clearly communicated to the supply chain.
By the time practical completion is reached, the information package is largely complete. If asset data is missing, drawings do not reflect what has been built, or documentation has not been validated, there is little opportunity to correct these issues without additional cost and delay.
The result is familiar to many estates-owning organisations. The project appears to have delivered everything required: models, drawings, O&M manuals, commissioning records and perhaps even a COBie file. Yet the estates and facilities management team still cannot rely on the information to operate, maintain or manage the building effectively.
The consequences extend far beyond handover itself. Poor quality information leads to delays importing data into CAFM systems, additional surveying, reactive maintenance, compliance risks and a loss of confidence in the information from the very first day of occupation.
This guide explains why BIM handovers fail, the common causes seen across capital projects and, more importantly, what organisations can do to avoid repeating the same problems.
What does a successful BIM handover actually look like?
Many organisations judge a BIM handover by the quantity of information received. A successful handover, however, is not measured by the number of files delivered but by whether that information is complete, accurate, validated and immediately usable by the people responsible for operating the building.
A successful BIM handover provides estates and facilities management teams with information they can trust from day one. Asset data imports successfully into the organisation's CAFM system, drawings reflect what has actually been constructed, documentation is linked to the correct assets and information has been reviewed throughout the project rather than assembled at the last minute.
Good handovers are not created during the final weeks of a project. They are the result of good information management from the earliest stages of procurement through to practical completion
In plain english
A BIM handover is only successful if your estates team can use the information immediately.
A folder full of drawings, O&M manuals and spreadsheets may look complete, but if the information is inaccurate, incomplete or incompatible with your existing systems, the handover has failed regardless of how much information was delivered.
The ten most common reasons BIM handovers fail
No Exchange Information Requirements (EIR)
The most common cause of poor handovers starts before the project even begins. Without a documented Exchange Information Requirement (EIR), the supply chain has no clear understanding of what information the client actually needs. Contractors will naturally deliver information using their own standards, templates and established ways of working, which are often geared towards design and construction rather than long-term operation of the building.
The result is a handover package that may appear comprehensive but does not reflect how the organisation manages its estate or how information needs to be structured for operational use.
Information requirements are copied from previous projects
Many organisations begin with an existing EIR or template, which is entirely reasonable. Problems arise when those documents are reused without reviewing whether they still reflect the organisation's current systems, operational processes or project objectives.
Changes to CAFM systems, asset management processes, statutory requirements or organisational priorities can quickly make an old template unsuitable.
Generic requirements almost always produce generic information.
Information requirements are defined too late
Information management should begin before the supply chain is appointed. If information requirements are introduced after appointment, contractors have often already established their workflows, agreed deliverables and priced the work.
Retrospective requirements are more difficult to achieve, usually require additional effort and often result in compromises that reduce the quality and completeness of the information ultimately delivered.
Information is only reviewed at handover
One of the biggest misconceptions is that information quality can be assessed at practical completion.
By this stage, most of the information has already been created. If errors, omissions or inconsistencies are discovered, they can be costly and time-consuming to correct. Effective information management involves reviewing information throughout the project, allowing issues to be identified while they are still relatively simple to resolve.
Handover should be the confirmation that information is ready for use, not the first time it is properly reviewed.
Asset data is disconnected from supporting documentation
A complete asset register has limited value if it cannot be linked to commissioning records, O&M manuals, test certificates or warranties.
Equally, a comprehensive set of manuals becomes difficult to navigate if assets cannot be easily identified within them.
Information should form a connected dataset rather than a collection of unrelated documents. Without these links, estates teams spend valuable time searching for information that should already be readily available.
COBie is delivered but never validated
Receiving a COBie file does not automatically mean the information is complete or usable.
Data may contain missing attributes, inconsistent classifications, duplicate assets or formatting issues that prevent successful import into the organisation's CAFM system. Unless the information is validated against agreed acceptance criteria before handover, these issues often remain hidden until operational teams attempt to use the data.
As-built information does not reflect what was actually constructed
Changes occur on every construction project. Equipment may be substituted, layouts amended or services rerouted.
If models, drawings and asset information are not updated to reflect those changes, the information handed to the client no longer represents the building they have taken ownership of.
This creates uncertainty from the outset and reduces confidence in the information provided.
Handover is treated as a single event rather than a process
Successful handovers are the outcome of good information management throughout the project.
Where information is left until the final weeks before completion, quality issues accumulate and the project team is forced to assemble large volumes of information under significant time pressure.
Important checks are missed, inconsistencies remain unresolved and operational teams inherit information that has never been properly managed.
There are no agreed acceptance criteria
Many organisations specify what information they expect to receive but never define what constitutes an acceptable deliverable.
Without clear acceptance criteria, it becomes difficult to determine whether information is complete, accurate or suitable for operational use.
This can lead to disagreements at handover and makes it much harder for the client to require deficiencies to be corrected before accepting the information.
Estates and FM teams are not involved
The people who will ultimately use the information are often consulted too late or not at all.
Project teams may define information requirements based on design or construction needs while overlooking the practical requirements of those responsible for operating and maintaining the building.
Involving estates and facilities management teams from the outset helps ensure information requirements are based on how the building will actually be managed throughout its life, rather than simply how it is constructed.
The cost of getting it wrong
Poor BIM handovers have consequences that extend well beyond practical completion. Where information cannot be trusted, estates teams often find themselves manually correcting asset data, commissioning additional surveys, recreating documentation or delaying the implementation of CAFM systems while information is cleansed.
The operational consequences can be significant, planned maintenance may be delayed, statutory compliance becomes more difficult to demonstrate, asset replacement decisions are made using incomplete information and organisations lose confidence in the very data they commissioned the project to deliver.
Perhaps most importantly, poor information is expensive to correct once a building is occupied.
The cost of resolving deficiencies after handover is almost always higher than defining and managing information properly throughout the project
Why clients ask Lynefield to support their BIM handovers
Many organisations have experienced at least one project where the information handed over did not meet operational needs. In most cases, the underlying causes can be traced back to information requirements that were either unclear, introduced too late or never actively managed during delivery.
Lynefield works exclusively on the client side, helping estates-owning organisations define clear information requirements, review information throughout project delivery and validate handover information before it reaches operational teams.
Whether developing Exchange Information Requirements, reviewing asset data, assessing BIM deliverables or supporting digital handover into CAFM systems, our focus is always the same: ensuring projects deliver information that estates teams can actually use.
Frequently Asked Questions
Is it too late to improve a BIM handover once the project has started?
Not necessarily. While information requirements are best established before procurement, meaningful improvements can often still be made by reviewing information during delivery and identifying issues before practical completion.
Is a COBie file enough for a successful handover?
No. COBie is only one method of exchanging structured asset information. A successful handover also depends on accurate drawings, linked documentation, validated asset data and information that reflects the organisation's operational requirements.
Who should review BIM handover information?
Responsibility should not rest solely with the design team or contractor. Estates, facilities management and client-side information management specialists should all be involved in reviewing whether the information meets operational needs.
How do we know if our asset data is good enough?
The simplest test is whether the information can be imported into your CAFM system and immediately supports day-to-day operation and maintenance. If significant manual correction is required, the information was not ready for handover.
Why do BIM handovers often fail despite having a BIM Execution Plan?
A BIM Execution Plan explains how information will be delivered. It does not define what information the client actually needs. Without well-developed information requirements, even an excellent BIM Execution Plan cannot produce the right operational information.
Can poor handover information be corrected?
Yes, but usually at considerably greater cost than getting it right during the project. Information audits, validation exercises and asset data remediation can improve existing information, although prevention is almost always more efficient than correction.
Need help improving BIM handover?
Lynefield helps estates and capital project teams define information requirements, review information throughout delivery and validate handover information before it reaches operational teams.
