Closing the Loop: Why Handover Deserves Its Own Phase on the Programme

There is a moment on most commercial projects when the work appears finished and everyone behaves as though it is. The ceilings are closed, the carpets are down, the furniture is arriving. And then three months pass.

This is the handover gap, and it is remarkably consistent. The last fraction of the job absorbs a disproportionate share of time, attention and goodwill, because it is the only part of the programme that nobody has genuinely planned. Practical completion is treated as a date rather than a process, and the process, when it arrives unmanaged, is slow.

The gap is structural, not accidental

The reasons are not mysterious. Fit-out and refurbishment trades are sequenced to reach a state of apparent finish, and the incentive structures reward getting to that state. Commissioning, snagging, documentation and training sit awkwardly at the end of that sequence, because they depend on other work being complete and they generate no visible progress. They are, in short, easy to defer.

There is also an organisational cause. The project team is assembled to deliver construction. The facilities team, the IT function and the occupier's operational leads join the conversation late, often after the building is substantially built. Their requirements then arrive as variations at precisely the point when the contractor is trying to demobilise. The resulting friction is predictable and largely avoidable.

Snagging is the smallest part of the problem

Snagging attracts the most complaint, but it is rarely the real obstacle. A well-run snagging process produces a list, allocates it, and closes it. The difficulty is that snagging is often the trigger for discovering larger omissions: a door that does not meet fire requirements, a control panel that has never been demonstrated, a service riser that cannot be accessed.

Two practices help. First, snag in zones as each area completes rather than in a single sweep at the end, so defects are corrected while the relevant trades are still on site. Second, agree in advance what constitutes a snag and what constitutes incomplete work. The distinction matters, because practical completion depends on it, and disputes over definitions are expensive.

Commissioning carries the evidence the building will need

Commissioning is where a project proves that the systems do what the specification said they would. It produces the records that the occupier will rely on for the life of the building: test results, balancing figures, control philosophies, certification.

Too often commissioning is scheduled after the services are installed but before the building is ready to be exercised properly, which produces results that are technically complete and practically meaningless. A building cannot be balanced convincingly while other trades are still working in the same space. Sequencing commissioning into a settled environment costs a few days and saves a great deal of subsequent investigation.

For occupiers in England and Wales, the Building Safety Act 2022 has also shifted expectations around information. The golden thread principle, whatever its precise application to a given project, has reinforced a simple point: the record of what was built and why is part of the asset, not an administrative by-product.

The documents that decide whether Monday works

An O&M manual assembled in the final fortnight, from whatever the subcontractors happen to send, is a liability. It will be incomplete, poorly indexed and unhelpful to the maintenance contractor who inherits it. The manual should be built as the works proceed, with a named owner and a contents schedule agreed at the outset.

The same applies to training. A session delivered to a facilities team on the day of handover, before the building has been occupied, teaches nobody anything durable. Training is more effective in two parts: an initial session during commissioning, and a follow-up once the occupier has been in the building for a few weeks and knows which questions to ask.

And the as-installed information, as distinct from the as-designed drawings, needs to be verified rather than assumed. Small deviations accumulate, and an accurate record of what is actually in the ceiling void saves hours on the first maintenance call-out.

A short checklist for the closing phase

• A handover plan agreed at contract stage, with named responsibilities and dated milestones.
• Occupier and facilities requirements captured during design, not during demobilisation.
• Zonal snagging as areas complete, with an agreed definition of a snag.
• Commissioning scheduled in a settled environment, with results reviewed rather than simply filed.
• O&M documentation compiled progressively against an agreed contents schedule.
• Two-stage training: at commissioning and after occupation.
• Verified as-installed records, including concealed services.
• A soft landings period with a clear point of contact and a defined defect response time.
• A final review of warranties, guarantees and certification, checked against the lease obligations.
• A lessons-learned session held while the team still remembers the detail.

Goodwill is a project resource

The final phase is where the relationships built over a programme either carry a project over the line or fail at the worst moment. A contractor asked to return repeatedly to a building they consider complete will price that experience into the next tender, and the occupier will feel the difference in responsiveness long after the defects period ends.

The practical remedy is unglamorous: give handover a phase of its own, resource it, and hold it to dates in the same way as the construction works. A project that finishes two weeks later than the programme but hands over a building that works, with records that stand up, has not lost time. It has avoided a much longer delay, deferred.
