How is decanting managed when a building has to stay operational?

Some refurbishment can be done around the people using the building. Some cannot, and pretending otherwise produces a programme that fails and a building that functions badly for months.

Decanting is the alternative: move the occupants out, do the work properly and continuously, move them back.

When decanting is the right answer

**The work is continuous and disruptive.** Structural work, [strip-out](/answers/demolition-and-strip-out-in-occupied-buildings), services replacement, anything that cannot be started and stopped within a shift.

**The space cannot be handed back usable each day,** which is the test for whether out-of-hours staging is viable.

**The hazard cannot be contained** to a standard suitable for the occupants, which in a school or a health setting is a higher bar than in a commercial building.

**The programme saving is large.** Working around occupants can double a programme. Where the temporary accommodation costs less than the extension, decanting is the cheaper answer as well as the better one.

What the temporary accommodation has to be

The common failure is treating the decant space as a compromise rather than a facility.

It has to be usable for the actual function: the right size, the right services, the right furniture, heating and cooling, data, and an accessible path to it. A classroom decanted into a space with no data and no shade is a term of poor teaching.

It also has to be ready and proven before the move, not on the day. The move happens into a working space, or it happens twice.

Planning the move

**Timed to the operational calendar.** School holidays, semester breaks, a quiet clinical period. Moving a functioning department mid-term because the construction programme said so is how a project loses the client's support.

**Everything labelled and scheduled,** including what is being stored, what is moving and what is being disposed of. A decant is also the point at which a building's accumulated contents get sorted, and allowing for that is realistic rather than optimistic.

**Services in the temporary space live and tested,** including the things nobody thinks about until they are missing: printing, phones, the intercom, the fire system coverage.

**The return move planned at the same time,** with a date, because a decant with no defined end becomes permanent in everybody's mind.

The communication

The occupants of a decanted space are the people most affected by the project and usually the last to be told.

Monument works to a stated programme with the dates, the sequence and the return communicated before the move, and the director on site through it, because a question from a head teacher or a facility manager on the day needs an answer on the day.

Staging across a large project

On a project with several areas, decanting can run as a rolling sequence: one area out, worked, returned, the next area out into the same temporary space.

That reuses the temporary accommodation across the whole project rather than providing it for everybody at once, which is usually the difference between a decant being affordable and not.

It requires each stage to finish on time, because the next move depends on it.

The alternative is worse than it looks

A building worked around for a year is a building with dust, noise, closed corridors, relocated facilities and interrupted routines for a year.

The measured comparison is usually clear once the operational disruption is costed alongside the construction, rather than only the construction.
