Renovation Schedules: Planning Work and Deliveries

A good renovation schedule is more than a task list: it combines lead times, drying periods, decision deadlines and dependencies in one plan. Here is how to build one.

Many renovation schedules are really just an ordered list of tasks: demolition, electrics, plaster, tiles, paint. Such a list shows what gets done but not when each thing needs to be ready. A working schedule brings together three things: the tasks, the materials that make them possible and the decisions the client must make.

Order tasks by dependencies

The foundation of the schedule is the question “which task can follow which?” Electrical and plumbing runs come before plaster, screed before floor finishes, waterproofing before tiles. Other tasks are independent and can run in parallel – bathroom tiling and a bedroom ceiling installation, for example.

To identify dependencies, ask two questions for every task: what must be ready before it starts, and what does it unlock once it is finished? The answers reveal the critical path – the sequence of tasks whose delay delays the whole renovation.

Work backwards from delivery times

Materials need to be thought about well before the day they are needed. The practical method is to work backwards. Find the date tiling starts, then subtract delivery time, order confirmation time and the days needed to choose. The result is “tiles must be chosen by this date at the latest”.

This calculation is especially important for:

• imported or special-order tiles, stone and sanitary ware;
• made-to-measure windows, doors, glass partitions and stairs;
• built-in items: concealed cisterns, installation frames, bathtubs;
• air-conditioning and ventilation equipment, because their lines are installed early.

Note that some items are only fitted just before finishing, yet their technical dimensions must be known during rough works. A wall-hung toilet frame, for instance, goes in before plastering.

Supply is not just ordering; it also means receiving and storing. The site needs a dry, safe place for materials, and large quantities of tiles or parquet delivered far too early get in the workers’ way and are more likely to be damaged. That is why some items are delivered in portions, in step with the work.

Put decision deadlines into the schedule

Client decisions should appear as separate lines: “approve lighting points”, “select bathroom tiles”, “choose door model”. Each line shows a deadline and the tasks that depend on it.

This helps in two ways. The client sees in advance what needs deciding and when, and the contractor can explain the impact of a late decision on the timeline with clear reasoning.

Drying periods and buffer days

Drying and curing periods should be written into the schedule as stages in their own right, not left as gaps. This sets the client’s expectations correctly and makes it possible to plan parallel work in other rooms on those days.

It also makes sense to keep a few buffer days on the critical path. A delivery arriving a day or two late, a tradesperson falling ill or an unexpected hidden problem should not wreck the whole schedule.

A schedule is a living document

Once work starts, the schedule needs regular updating. A short weekly review is enough: what is finished, what is running late, which materials are on the way, which decisions are pending. Sending the updated version to the client ensures both sides see the same picture.

In an operating office or commercial space the schedule also carries extra constraints: hours for noisy work, relocating staff, closing sections in turn. If these conditions are not included in the first version, they require major revisions later.

The format of the schedule matters too. Complex software is not always needed: a simple table with weeks in columns, tasks in rows and colour-marked delivery and decision dates is often enough. What matters is that both contractor and client can read it easily and see clearly what changed with each update.

Quick checklist

• Predecessor tasks are defined for every task.
• Latest selection dates have been worked back for long-lead materials.
• Client decisions appear as separate lines with dates.
• Drying periods and buffer days are visible.
• The update frequency and format of the schedule have been agreed.
