Phase 3: Build

Services & fixes

This challenging activity shifts students’ focus to the detailed craft tasks that fit out a building’s interior. It introduces the idea of first and second fixes and again emphasises the importance of planning and supervision. Students can consider their own roles if they plan to enter a craft trade.

Services and fixes


  • Use What happens when? to introduce the topic.
  • Consider the lab scenario, or use one of your own.
  • Discuss why services need to be completed in two stages like this.

Main activity

  • Explore Put the jobs in order as a whole class. Help each student to understand that there are three different tasks that split the jobs into ‘before’ and ‘after’: walls, ceiling and floor. Which jobs relate to the wall, ceiling and floor?
  • Students work in pairs to divide the list of jobs into ‘before’ and ‘after’.
  • Optional: they then put their new lists into order, and create a briefing note (list of tasks) for one of the trades involved.


  • Discuss how the site planner might work with the craft foremen to organise this. What documents or meetings would help work to proceed smoothly?


Easier/Level 1:
This will require simplification for Level 1 learners – extract some tasks (for example just those relating to the wall) and limit students to organising these. Or, assign students a trade and ask them to identify the tasks that are relevant to them, then put these into ‘before’ and ‘after’ groups.

Get students to organise jobs into order, and add other tasks that they think would be required.


Many large buildings use lightweight/stud (partition) walls as well as masonry (traditional) construction, which may only be used for outer walls and the central atrium or light well. Can students explain the benefits of partition walls for the building owner, and for the people who are installing services? How might the task of connecting services vary between a traditional and partition wall?

Again, you can link this to Safety and consider how different craft trades can work together in busy conditions, highlighting communication and co-operation.
