Site diary for a commercial fit-out: what to record

A commercial fit-out is a fast job in someone else's building. The programme is tight, the mechanical and electrical work is heavy, trades run in parallel, and almost everything, from access to deliveries to isolations, has to be booked with a landlord or building manager who is not on your team. The daily site diary is what keeps that coordination straight and protects you when a delay is not of your making. This guide sets out what a commercial fit-out diary should capture, a worked example of a real day, and how to log it from your phone without losing an hour to paperwork.

What a site diary for a commercial fit-out needs to capture

A generic template records the weather, which barely matters indoors. On a fit-out the value is in the coordination, the M&E and the pace. Record these every day:

• Landlord and building management coordination. Access, permits, service isolations, use of common areas, lifts and the loading bay, and any approval requested, agreed or refused
• Out-of-hours working. Any noisy or disruptive work done outside normal hours where the building is occupied, and what was agreed
• Labour and trades. Every trade and subcontractor on site with numbers, since fit-outs run many in parallel
• Deliveries. Materials in through booked goods-lift or loading-bay slots, and any missed or delayed slot
• Mechanical and electrical progress. HVAC, power, lighting, fire alarm, sprinklers and data, and any commissioning started
• Work done by area or zone. Progress across the floor plate and its stage, from strip-out and CAT A to CAT B fit-out and finishes
• Instructions and variations. Client and design changes, and conditions found once ceilings and voids are opened
• Delays. Time lost to access, landlord coordination, long-lead M&E items or awaited information, with the cause
• Health and safety. Permits, hot works, isolations, and protection of the landlord's areas and finishes
• Inspections and photos. Building control and landlord inspections, and photos of services and structure before the ceilings close

A worked commercial fit-out diary example

Here is what a solid entry looks like for a single day on a CAT B office fit-out over an occupied floor. It is illustrative only, but it shows the level of detail that stands up later.

Tuesday. On site: partition contractor (4), M&E first fix (6), ceiling fitters (3), site team. Access: goods lift booked 07:00 to 11:00 for partition track delivery, one slot only, granted by building management. Out of hours: floor coring to level below agreed for 18:00 to 20:00 to avoid disruption to the tenant. M&E: first fix containment and power to Zone B 70 percent, sprinkler drops set out, fire alarm cabling started. Work: metal stud partitions to Zone B lines complete, ceiling grid started Zone A. Delay: air handling unit delivery slipped to next week, long-lead item, noted as a programme risk. Instruction: client added two extra data points to each meeting room, logged as variation. Landlord: requested method statement for the out-of-hours coring, issued. Photos: containment and services in Zone B ceiling void before close, partition layout.

Compare that to "carried on with partitions and M&E". One records the coordination and the money. The other records nothing.

Why it matters on a commercial fit-out

A fit-out dispute is usually about the programme and who caused the slip, and the answer is nearly always in the coordination the contractor does not control. The diary is what turns that into evidence.

If the loading bay was only released for one slot a day, or a service isolation the landlord promised did not happen, dated entries are what support a fair extension of time. If the client kept adding scope, the record of instructions is what supports the variations. And a fit-out closes up its M&E in the ceiling void quickly, so the photo taken before the tiles go back is the only proof the services behind them were installed correctly. On a job this fast and this dependent on others, the record has to be made on the day or it is gone.

Paper vs phone on a commercial fit-out

A paper diary cannot keep up with a fit-out. The pace is high, the coordination changes by the hour, the photos of the M&E sit on several phones, and matching them to the right day and zone later is guesswork. By the time a claim about the programme comes up, the paper record is thin.

Logging from a phone fits the job. The delivery slot, the isolation request and the photo of the ceiling void attach to that day as you record them, timestamped, and the record cannot be quietly rewritten afterwards. Plant rooms, cores and basements often have no signal, so the tool has to work offline and sync later. A diary that needs a connection to save is no use in a riser cupboard.

Frequently asked questions

What is different about a commercial fit-out site diary?

A commercial fit-out happens inside someone else's building, on a tight programme, with a lot of mechanical and electrical work and many trades in parallel. So the diary leans heavily on landlord and building management coordination, access and out-of-hours working, delivery slots through the goods lift or loading bay, and M&E progress, on top of the usual daily record.

Why record landlord and building management coordination?

Access, service isolations, use of common areas, lifts and the loading bay, and approvals all sit with the landlord or building manager, and they are a common cause of delay. A dated record of what was requested, agreed or refused is what supports a fair account if their coordination held up the works.

How do you record variations on a fit-out?

Log each instruction on the day with who gave it and the work or time affected, and attach a photo where relevant. Fit-outs are variation-heavy because client requirements change and existing conditions appear once the ceilings are open, so a clear contemporaneous trail turns changes into agreed variations rather than disputes.

How does FORGE Command help on a commercial fit-out?

FORGE Command lets the site lead log the day from a phone in a couple of minutes, attach photos to each entry, and have every record stamped with GPS, weather and time.
