What Building Owners Actually Need at Handover

Handover Is More Than Handing Over the Keys

After months or even years of construction, practical completion can feel like the finish line.

For the project team, it largely is.

For the building owner, however, it marks the beginning of something much longer: the operational life of the building.

Once contractors begin leaving site, responsibility for operating and maintaining the building moves towards the owner and their facilities teams.

The question is: have they been given everything they need to do that effectively?

A successful handover isn't simply about delivering a large collection of files. It's about giving the people responsible for the building the information they need to understand it, operate it safely and maintain it for years to come.

1. A Complete O&M Manual

The Operation and Maintenance (O&M) manual remains one of the most important parts of building handover.

It brings together information about how the building and its systems should be operated and maintained.

A good O&M manual may include manufacturer information, operating instructions, maintenance requirements, commissioning information, product details, warranties and relevant certificates.

But simply having an O&M manual isn't enough.

It needs to be complete, well organised and easy to navigate.

A 5,000-page collection of poorly labelled PDFs technically contains information, but that doesn't necessarily make it useful to the person trying to find a particular maintenance instruction six months later.

2. Accurate As-Built Drawings

The drawings used during construction don't necessarily represent exactly what was eventually built.

Changes happen.

Services move. Equipment changes. Layouts are adjusted. Details are modified to deal with conditions encountered on site.

That's why building owners need accurate as-built information showing the building as it exists at completion.

Depending on the project, this could include architectural drawings, mechanical and electrical layouts, public health services, fire strategy information, schematics and other relevant records.

These drawings can become invaluable when maintenance, refurbishment or future construction work takes place.

3. A Useful Asset Register

Building owners shouldn't have to rediscover what equipment has been installed in their building.

A comprehensive asset register provides a structured record of maintainable assets and the information associated with them.

That could include boilers, air handling units, pumps, lifts, fire safety equipment, electrical systems and other building services.

Useful asset records might contain details such as the manufacturer, model, serial number, location, installation date, warranty information and maintenance requirements.

This gives facilities teams a much stronger starting point for managing the building from day one.

4. Warranties and Guarantees

When something fails shortly after handover, one of the first questions is often:

“Is it still under warranty?”

Building owners should receive clear records of relevant warranties and guarantees, including information about what they cover, when they started and when they expire.

These records should also be easy to retrieve.

Having a warranty buried somewhere inside hundreds of folders can make something technically available but practically difficult to use.

5. Testing and Commissioning Records

Before building systems enter normal operation, many will have been inspected, tested and commissioned.

Those records provide evidence of the condition and performance of systems at handover and can give facilities teams an important baseline for future operation.

Building owners should therefore receive the relevant commissioning certificates, test results and associated records required for their building and its systems.

This isn't just historical information. It can be valuable when diagnosing problems or comparing future performance.

6. The Health and Safety File

Where required under CDM 2015, the Health and Safety File contains information needed to help protect people carrying out future construction work on the building.

It should contain relevant information about risks that may need to be considered during later maintenance, refurbishment, alteration or demolition.

For the building owner, this is important information that needs to remain available throughout the life of the asset.

It shouldn't simply disappear into an archive once the project has finished.

7. Fire and Life-Safety Information

Building owners also need to understand the systems and measures designed to protect people in an emergency.

The information required will depend on the building, but may include relevant fire strategy information, fire alarm details, emergency lighting records, fire door information and information relating to other installed fire and life-safety systems.

For buildings within the scope of additional building safety requirements, there may also be further information-management obligations.

The important principle is simple: critical safety information needs to remain accessible to the people responsible for the building.

8. Maintenance Requirements

Knowing what equipment is installed is only half the job.

Building owners also need to know what needs maintaining, when and how.

Manufacturer recommendations, statutory inspection requirements and planned maintenance information can help facilities teams begin developing an effective Planned Preventative Maintenance (PPM) programme.

This is where good handover information begins to directly influence the future performance of the building.

If maintenance information is incomplete, facilities teams may spend their first months trying to reconstruct information that should already have been available.

9. Contact and Supplier Information

When an issue arises, knowing who installed something can be almost as important as knowing what was installed.

Building owners may need details for manufacturers, specialist subcontractors, installers and other organisations associated with important systems.

This can be particularly useful during defects periods, warranty claims or when specialist maintenance is required.

Again, this information becomes much more useful when it is structured and easily searchable rather than scattered across old emails and documents.

10. Information People Can Actually Find

This may be the most overlooked part of handover.

A building owner can technically receive every required document and still experience a poor handover.

Why?

Because having information and being able to use it are two different things.

If documents are spread across folders, USB drives, email attachments and disconnected systems, finding something can become unnecessarily difficult.

A facilities manager standing in a plant room shouldn't need to search through dozens of folders just to identify an asset or find its manual.

A good handover therefore needs to consider not only what information is provided, but how that information will be accessed after the project team has gone.

The Handover Should Work for the People Using the Building

One of the easiest mistakes to make is viewing handover entirely from the construction team's perspective.

The objective becomes:

“Have we delivered everything?”

But perhaps the better question is:

“Can the building owner actually use what we've delivered?”

That small change in perspective makes a significant difference.

The person receiving the information may not have been involved in the construction project. They may not understand the project's original folder structure or know which subcontractor produced a particular document.

Information should therefore be structured around the needs of the people who will operate the building for the next 10, 20 or 30 years.

Handover Shouldn't Happen at the Last Minute

Another common problem is leaving handover information until the end of the project.

When documentation is collected retrospectively, teams can find themselves chasing subcontractors for missing certificates, manuals, drawings and asset information just as everyone is trying to close out the project.

A better approach is to consider information requirements from the beginning and build the handover record progressively throughout construction.

This gives teams more opportunity to identify gaps, review information and ensure the final record accurately reflects what has been delivered.

By practical completion, handover should be the culmination of an ongoing process rather than a last-minute document collection exercise.

What Happens to the Information After Handover?

Receiving good information at practical completion is essential.

Keeping it accurate afterwards is just as important.

Buildings don't remain exactly as they were on handover day. Assets are serviced and replaced, spaces are altered, inspections take place and new information is created.

That means the original handover record should provide the foundation for the building's ongoing information.

Rather than becoming a historical snapshot that gradually falls out of date, it can evolve into a live building record.

How Liaison View Supports Building Handover

Liaison's View platform provides building owners with a central environment for accessing and managing their building information.

O&M documentation, drawings, Health & Safety information and other important records can be organised and made accessible without relying on complicated folder structures or physical copies.

This means the information carefully created during construction can continue providing value throughout the operational life of the building.

When combined with Maintain, organisations can also connect this information with ongoing maintenance activity and asset history, helping bridge the gap between project handover and long-term facilities management.

A Better Definition of a Successful Handover

Perhaps we need to think differently about what successful handover actually means.

It's not:

“We sent the documents.”

It's:

“The people responsible for this building have the information they need to operate, maintain and understand it.”

That's a much higher standard.

But for a building that could remain in use for decades, it's one worth aiming for.

Conclusion

Building handover is one of the most important transitions in a project's lifecycle.

The construction team may be leaving, but the people responsible for operating the building are only just getting started.

Giving them accurate drawings, O&M information, asset records, warranties, certificates, safety information and maintenance requirements provides the foundation they need.

But the best handovers go further.

They make that information structured, accessible and useful.

Because ultimately, a successful handover shouldn't be measured by how many documents were delivered.

It should be measured by how useful those documents are the day after everyone else has left site.
