Office renovation in Dubai: rebuilding around a working team

Refurbishment, renovation and fit-out are not the same scope

A fit-out turns a shell or a landlord's Cat A floor into a usable office for the first time. Partitions, ceilings, flooring, power, data, air conditioning distribution, joinery, all of it new. Our office fit-out service page covers that route.

A renovation reworks a space that has already been built out once. You inherit somebody else's layout, somebody else's cable trays and a ceiling void full of surprises. Refurbishment usually shows up in landlord and property language, meaning an upgrade of the base building or a Cat A refresh between tenants. Tenants say renovation when they mean their own space.

None of those three words carries a fixed legal meaning in a Dubai lease or a contractor's quotation. Arguing about terminology wastes a meeting. Argue about the scope schedule instead: what gets stripped out, what stays, who tests what stays, and who pays when the test fails.

Why office renovation in Dubai costs differently from a new fit-out

There is no honest rate per square foot for a refurbishment, and anyone who gives you one over the phone is quoting a different building. The variables that move a renovation number are not the same as the ones on a new fit-out, so a benchmark from an empty unit will mislead you. The factors that actually drive it:

• Strip-out and disposal. Demolition is labour plus transport plus tipping, and on an occupied tower it often happens outside working hours through a booked service lift.
• What is hiding above the ceiling. Until tiles come down in a few positions, nobody knows the real condition of the ducting, the trunking or the sprinkler pipework.
• MEP rework. On our own cost per sqft breakdown we put mechanical, electrical and plumbing at twenty to thirty per cent of a straightforward Cat A budget, and at forty to fifty-five per cent on a refit where the ceiling comes down. That gap is the single biggest reason renovation budgets set from fit-out benchmarks blow up.
• Restricted hours. The same trade doing the same work in four-hour night windows takes more calendar days and more supervision than it does on a free floor.
• Protection and making good the common areas. Lift lobbies, corridors and the goods lift get protected before the first tool arrives, and get handed back clean.
• Phasing. Every phase is another mobilisation, another set of barriers, another clean.

Zone the floor before you draw anything

The first drawing on an occupied job is not the layout. It is the zoning plan: which part of the floor is live on which week, where the staff sit while their corner is a building site, and where the boundary between the two runs.

Swing space is the part clients underestimate. Sometimes it exists on the floor, a meeting room suite or an under-used open area that absorbs twenty desks for six weeks. Sometimes it does not, and the honest answer is a temporary unit in the same tower, split shifts at home, or accepting that the programme has to run in four phases instead of two.

The comms room is the exception to phasing. Servers, patch panels and the building's incoming links are one system, and moving them is a planned weekend event with the IT provider on site, not something that gets squeezed between partition works. We fix that date early and build the rest of the programme around it.

The staff need one route across the floor and the site needs another. If the only route to the site runs through the live office, the job will be slower and dirtier than anyone quoted, and someone will eventually walk a sheet of plasterboard past a client meeting.

Escape routes are the constraint people forget. The live side has to keep a compliant route to the staircase for the entire duration of the works, which sometimes means the hoarding line moves for a reason that has nothing to do with the sequence you wanted.

Night shifts, weekend windows and the building's clock

An occupied tower gives you hours, not days. Which hours is a building management decision, not a public timetable, and it varies more than tenants expect. Some towers permit core drilling only after 19:00, or allow Saturday works but not Friday. Mixed-use buildings with residential floors above the office levels often ban night work outright, because the complaint comes from a resident and not from a tenant.

What we agree with the building before mobilising: noisy trade windows, goods lift slots, loading bay times, waste removal routes, worker access passes, and who is allowed to isolate the fire alarm on which day.

The UAE midday break runs 15 June to 15 September, 12:30 to 15:00, and applies to work in open air and under direct sun. Inside a conditioned floor it does not stop the trades, but it does hit deliveries, loading bay handling and anything on a terrace, so summer programmes carry a different logistics plan from winter ones. Ramadan shortens the private-sector working day by two hours under MOHRE rules, which changes both the client's day and the site's, and it should be in the programme before it is signed rather than discovered in week three.

Night work buys you continuity, and it costs output per hour. Fewer trades on site at once, more supervision per head, and a longer wait when a material turns out to be wrong at 23:00 with the supplier's warehouse shut. We price it as what it is rather than as a free option.

Dust, noise and air on the live side

Dust barriers are not sheeting taped to a wall. On a job running more than a few weeks we build a stud and board partition from floor slab to soffit, sealed at the joints and at the head, with a self-closing door and a tacky mat inside it. Short jobs get zip walls with a proper frame. Either way the barrier goes above the ceiling line, because the void is the first thing dust travels through into the live office.

The second path is the air conditioning. If the works zone and the live zone share a return air path, dust will be on every desk on the floor by Wednesday, no matter how good the partition looks. Isolating the zone, capping the returns and running a HEPA air scrubber to hold the work area at negative pressure is what keeps the barrier honest.

Fire detection is where occupied jobs go wrong loudly. Grinding, drilling and hot works near a smoke detector without an agreed isolation will evacuate the tower, and after that conversation with the building manager the rest of the programme gets harder. Isolation is arranged in advance with building management and the DCD-registered maintenance company, logged in and out on the day, and never left over a weekend.

What to do with the existing MEP

We decide what to keep or replace from test results, not from guesswork. Before pricing we want the ceiling open in a few positions and readings on paper.

Usually worth keeping: chilled water risers, the main distribution board if capacity and condition support the new load, the sprinkler main, and the primary containment where routes still make sense.

Usually replaced: flexible ducting and diffusers once zoning changes, small power and data, lighting and controls, thermostats, and anything with visible corrosion or a batch of failed insulation resistance readings.

The tests worth paying for before the design freezes are insulation resistance on the circuits you plan to reuse, a load check on the board, airflow and balance readings on the existing units, and a sprinkler head coverage check against the new partition layout. That last one catches the most expensive surprise. Move a wall and you move heads, detectors, exit signage and sometimes the escape route width, and at that point a cosmetic refresh has become a fire strategy change with a submission behind it.

Reusing tired MEP looks like a saving until the commissioning sheet comes back. We would rather say that at quotation stage than at handover.

Approvals when the building is occupied

Which authority governs your job depends on the land, not on the type of work. Mainland offices run through Dubai Municipality. TECOM clusters and Dubai Design District sit with the Dubai Development Authority. Nakheel land including Palm Jumeirah goes through Trakhees. JLT goes through DMCC. DIFC runs its own building control, and Dubai Civil Defence sits across all of them.

Occupied buildings add a layer that empty shells do not have in the same form: the building management approval. Expect to submit a method statement, a risk assessment, insurance certificates, the contractor's trade licence and Civil Defence delegate registration, plus worker passes and per-shift work permits. Some towers want a refundable fit-out deposit before a single box arrives.

We do not quote approval durations as a promise. They move with the authority, the completeness of the submission and how many revision rounds the drawings need. What we do commit to is running the submissions in parallel with procurement instead of in series, because that is where the recoverable weeks are.

The reinstatement clause decides how you renovate

Read the end-of-lease clause before the layout is drawn, not in the final year. Many Dubai office leases require the tenant to return the unit to Cat A or to its original condition, which means the partitions you build today are a cost twice: once to install, once to remove and make good.

That single clause changes design decisions. Demountable partitions instead of built-in walls. Fewer penetrations into the slab. Written landlord consent for anything you want to leave behind, obtained now while the relationship is good rather than during a deposit argument three years later. What the strip-out actually involves is covered in our piece on office reinstatement in Dubai.

Phasing to spread the budget

Phasing works, with one rule: design the whole floor once, then build it in parts. Designing phase by phase produces a floor that reads as three different offices and an MEP layout that fights itself.

What resists phasing is the services and life safety package. Sprinkler modifications, detection and the associated inspection tend to want a single commissioning event rather than three, so the fire and MEP scope often runs ahead of the finishes phases rather than alongside them.

Phasing also has a price: repeated mobilisation, quotations that expire between phases, and material batches that no longer match. Carpet dye lots and veneer leaves are the usual offenders. Price the full scope once, then draw the phase lines on a priced document, and you will see what each split actually costs before committing to it.

What we ask before quoting an occupied office renovation

For reference, our JLT office at 150 m² ran twelve weeks in a tower that never stopped trading. A 95 m² unit was handed over in eight weeks, with the space vacant before handover. Same city, same trades, different access.
