Project handover is a critical phase in construction. Every contractor knows that a successful handover relies heavily on subcontractors delivering the right information at the right time. Yet in too many projects, vague instructions and unrealistic deadlines set the supply chain up to fail.
If subcontractors don’t understand exactly what’s required for Operations & Maintenance (O&M) manuals or handover documentation, the result is predictable: poor-quality submissions, last-minute scrambles, and strained client relationships.
At Zutec, we’ve analysed data from over 5,000 completed project handovers. The solution is simple but powerful; set your supply chain up for success from the very beginning.
The Project Handover Supply Chain Playbook
Why most supply chains struggle at Handover (And what you can do differently)
The risks of vague O&M instructions in construction Handover
It’s astonishing how often subcontractor orders still include requirements like “Provide O&M two weeks before PC.” On paper, it looks straightforward.
In practice, it’s a recipe for disaster. With only a vague deadline and no clarity on formatting, templates, or expectations, subcontractors scramble to pull something together under pressure.
Submitted information is sometimes incomplete, inconsistent, or unusable. Project managers are forced to spend hours chasing corrections and reformatting documents.
The end result is the same: delayed approvals, frustrated clients, and a handover process that feels chaotic rather than controlled.
How poor communication disrupts your project Handover timeline
When subcontractors are left in the dark, the consequences impact the entire project. Information arrives late or in the wrong format, creating bottlenecks that stall the handover process.
Contractors then scramble to fix issues in the final weeks of a project, drawing time and attention away from more critical tasks like commissioning or snagging.
For the client, the outcome is equally damaging. They encounter delays, receive documentation that lacks consistency, and frequently inherit O&M manuals that are difficult to navigate.
As a result, there is typically limited engagement upon delivery, and building manuals are not utilised as intended. Over time, this undermines trust and increases the likelihood of disputes over completion or payments.
Defining precise construction Handover deliverables from day one
The key to avoiding this chaos is clarity. At the procurement stage, contractors must set out detailed requirements for deliverables, formats, and timelines.
This doesn’t just mean stating that an O&M manual is required; it means specifying exactly what each trade needs to submit, by when, and in what structure.
Having a dedicated team working with subcontractors from templates and checklists is particularly effective. It removes ambiguity, standardises submissions, and ensures consistency across the entire project.
When trades know what’s expected early on, they can plan and allocate resources more effectively, rather than scrambling at the end.
Real-world success: How Willmott Dixon streamlined Handover with Zutec
Before adopting Zutec, Sarah Frith, Head of Design at Willmott Dixon, managed handovers using manual processes. A dedicated team member handled O&M documentation via Excel trackers and shared folders.
While this worked for smaller or staggered sites, it became unsustainable as the number of homes and concurrent handovers grew. The team faced significant time constraints chasing over 30 supply chain contributors for documentation.
Zutec provided a consistent framework to guide customers through their documentation requirements logically and efficiently.
By partnering with Zutec, Willmott Dixon streamlined its handover process, reduced manual effort, and improved the experience for both internal teams and end users. The structured approach enabled better planning, clearer communication, and more reliable delivery of critical documentation.
“With Zutec, we went from chasing 30+ supply chain partners and wrangling endless Excel trackers to having a clear, real-time dashboard that could handle even our most complex projects. Their depth of experience meant they could manage fluctuating resourcing, multiple sites handing over at once, and incredibly detailed O&Ms, health and safety files, and home user guides — all in a logical, structured way. It saved us huge amounts of time, made life easier for our clients and building managers, and gave us complete confidence in delivering quality handovers.”

The key to construction Handover success: Clear and structured subcontractor instructions
The success of your handover doesn’t just depend on your project team; it depends on how well your supply chain is set up to deliver. Vague instructions create stress, waste time, and damage client relationships. Clear, structured requirements empower subcontractors to deliver quality information on time and ensure handover is smooth, not stressful.
By setting your supply chain up for success, you protect your reputation, reduce risk, and strengthen client relationships. And with Zutec’s managed service and digital tools, you can make this process of creating and O&M Manual simple, efficient, and consistent across every project.
