The construction-to-operations gap appears when a project is declared complete but the owner still lacks reliable, usable information to run and maintain the asset. Closing it requires more than handing over drawings or a BIM model: the owner must define information requirements early, involve operations staff, require structured asset records, and test the deliverables in the systems and workflows that will use them.
What the construction-to-operations gap means
“Construction-to-operations gap” is a practical description, not the name of a formal standard. Authoritative guidance generally calls the activity asset information handover, project closeout or a digital handoff.

The National Academies of Sciences, Engineering, and Medicine defines asset information handover as “the process by which an asset owner gains the information and data required to appropriately manage and maintain constructed assets (the built environment) throughout the intended useful life of each constructed asset, system, item of equipment, or component.” The definition covers the whole operating life, not merely the date of practical completion. See the conclusion to chapter 12 of ACRP Research Report 264.

A room schedule, equipment list, warranty, commissioning record or maintenance instruction may exist somewhere in a document repository, yet still be unusable if it is incomplete, ambiguously named, inaccessible to the right team or impossible to import into the owner’s systems.
Why closeout packages often fail operations
- Requirements arrive too late. If the owner’s information needs are not part of the contract and closeout plan, project teams may optimize for design and construction records rather than maintainable asset data.
- Operations is treated as a recipient. Facilities staff know which attributes, locations, spares, certificates and maintenance tasks matter. Excluding them leaves those decisions to people who will not run the asset.
- Files are mistaken for information. A folder of PDFs or a federated model does not guarantee that an operator can identify an asset, find its current record or transfer it into a maintenance workflow.
- Responsibility for corrections is unclear. Handover needs an owner for missing, contradictory or changed data, along with a route for approval and resubmission.
The National Academies’ guidance is written for airport operators, so its recommendations should be applied to airports in that context rather than presented as airport-specific rules for every building or infrastructure owner. Its broader closeout principle is transferable: define handover requirements in project documentation and involve staff from the departments that will use the information.
Start with owner-defined information requirements
The owner should state the required information before closeout—and preferably before procurement—then make it part of contracts, scopes, responsibility matrices and acceptance criteria. Requirements should identify both the information itself and the format, timing and quality test.
Specify the maintainable asset
List the asset classes that must be handed over: for example, air-handling units, pumps, electrical panels, fire systems, controls points or specialist equipment. For each class, define the identifier, name, location hierarchy, manufacturer and model, serial number, capacity or rating, installation date, warranty details, replacement parts, statutory certificates, commissioning results and preventive-maintenance instructions that the operator actually needs.

Require as-built information, operations and maintenance documentation, test and commissioning records, and the relationships that make the data navigable. An operator should be able to move from a space to the equipment in it, from equipment to its manuals and warranty, and from a system to the components and maintenance tasks that support it.
Assign ownership of the data
Set who creates, checks, approves and corrects each information set. Include submission stages, naming and classification rules, version control, security requirements and a process for changes discovered during commissioning or the defects period.
Put operations staff in the project, not at the end of it
Participation should span the owner’s facilities, maintenance, engineering, information-management and finance or procurement functions, as appropriate to the asset. Representatives should review the proposed attributes, inspect sample records and attend demonstrations before the final handover.

Early operational participation also exposes conflicts between systems. A maintenance group may need equipment identifiers and task templates, while controls staff need point lists and sequences, and an estate team may need space and occupancy relationships. Resolve those needs into one responsibility-led information plan rather than asking the contractor to guess at the end.
Use structured asset data, not only documents
COBie—Construction to Operations Building information exchange—is a structured data organization and delivery method maintained by the National Institute of Building Sciences as part of the National BIM Standard–US. NIBS says, “The COBie specification provides a standardized method for project teams to deliver the data necessary to maintain a facility in a digital format.” Its overview describes schedules plus as-built, operations and maintenance, and commissioning information. See NIBS COBie V3.
COBie is not a maintenance application and does not, by itself, prove that a handover is complete. It gives project participants a consistent way to organize maintainable asset information so an owner can populate or connect facility-management systems. NIBS describes uses in new construction, renovation and changes in facility ownership or management, and notes that the approach can be adapted to some infrastructure handovers. The owner still has to define the required fields, classifications and acceptance tests.
| Handover approach | What the owner receives | Operational risk |
|---|---|---|
| Document-only closeout | Drawings, manuals and certificates in folders | High: records may be difficult to search, reconcile or import |
| Structured data plus documents | Machine-readable asset records linked to supporting files | Lower, provided fields and identifiers match owner systems |
| Verified digital handoff | Structured records and documents tested by the receiving operations team | Lowest of these options, because usability and corrections are checked before acceptance |
Verify that the handover works
- Build a sample. Select representative assets from each class and require the project team to populate the agreed fields and links.
- Check completeness. Compare delivered records with equipment schedules, drawings, commissioning logs and installed assets. Investigate duplicates, missing serial numbers, wrong locations and obsolete documents.
- Test the import or connection. Load the data into the owner’s maintenance or asset platform, or run the agreed interface. Confirm that identifiers, hierarchy, dates, documents and maintenance templates survive the transfer.
- Run an operator task. Ask a facilities user to find an asset, open its current manual, confirm its warranty and create or locate a maintenance task. Record every workaround.
- Close defects under control. Assign each issue to a named party, set a due date, require a revised submission and retain the approved version. Acceptance should depend on the tested result, not on the volume of files delivered.
Digital handoff options and their limits
A digital handoff can connect design and construction information with operational workflows. One vendor-described example pairs Autodesk Tandem with Eptura Asset; Autodesk University presents it as an illustration of an evolution from design and construction to operations, not as independent proof that the combination suits every owner. Details are available in the 2024 Autodesk University session.
Evaluate any platform against the owner’s information requirements, data export and import capabilities, security model, change process and support for the asset type. A visually impressive digital twin is still a poor handover if its records cannot be maintained or used by the people responsible for the facility.
Systems differ by sector
Health-care facilities illustrate why architecture cannot be assumed. HFM Magazine’s May 13, 2025 discussion identifies CMMS for maintenance, BMS for building controls, and IWMS for workplace and asset management, and emphasizes collaboration for a useful digital-twin handover. That is a health-care facilities example, not a universal system blueprint; other owners may use different combinations or a single integrated platform. Read HFM’s facilities-management discussion.
A practical closeout checklist
- Owner information requirements approved before final closeout.
- Operations representatives named and participating in reviews.
- Asset classes, identifiers, locations and mandatory attributes agreed.
- As-built, O&M and commissioning records linked to the relevant assets.
- Structured data mapped to the owner’s maintenance and asset systems.
- Completeness, import and operator-task tests passed.
- Defects, corrections and final approvals tracked with accountable owners.
- Responsibilities for updating information after handover documented.
Frequently Asked Questions
Is COBie the same as a digital twin?
No. COBie is a structured method for delivering maintainable asset information. A digital twin may use that information alongside models, live data and operational workflows, but COBie alone is not a twin or a guarantee of complete handover.
Does handing over the BIM model satisfy operational requirements?
Not automatically. The model must contain the owner’s required maintainable-asset data, connect to supporting records and pass usability tests in the receiving operational workflow.
The Bottom Line
A successful handover is an operational outcome: the right people receive complete, structured and verified asset information in a form they can use and maintain. Define that outcome in the contract, involve operations throughout delivery, and make acceptance depend on a demonstrated working transfer.
