Programming and plannning Flashcards
What are the names of each stage identified in the RIBA Plan of Work?
Stage 0 - Strategic Definition
Stage 1 - Prep and briefing
Stage 2 - Concept design
Stage 3 - Spatial Coordination
Stage 4 - Technical Design
Stage 5 - Manufacturing and construction
Stage 6 - Handover
Stage 7 - Use
Why do we have the RIBA Plan of Work?
The RIBA Plan of Work organises the process of briefing, designing, constructing, and operating
building projects into eight stages.
The Plan of Work explains outcomes, core tasks and information exchanges required at each stage.
What does RIBA stand for
Royal institute of British Architects
What is a programme and why do we need one for a construction project?
The programme should reflect the scope of work, identify activities and sequence those activities efficiently; a well-executed construction programme outlines each step and provides dates for completion.
Maintaining an effective programme is key to identifying potential risks, minimising delays and ensuring the project is completed on time.
The programme is used to both plan work and monitor progress.
What information does a programme typically show?
Activities and their sequencing.
Activity duration including the start and finish date.
Activity dependencies.
Milestones (key dates).
Float and lag.
Critical path.
Current and predicted progress.
The programme can also be used to predict cash flow and resource requirements (plant and labour).
What is programme float?
Float is the amount of time an activity can be delayed without delaying the subsequent activity or critical path.
What is lag between activities?
When the first activity completes and there is a delay before the second activity starts, this is called lag.
Can you provide a working example of lag on a new build project?
Once a concrete foundation is laid, there will be lag prior to erecting steelwork (to allow the concrete to
cure/harden). The below example shows a 5-day lag between the two activities.
What is the critical path on a programme?
The critical path is the longest sequence of activities that must be completed to successfully conclude a project.
Activities on the critical path are known as critical activities because if they’re delayed, the whole project will be delayed.
Can critical path activities have float?
Critical path activities have no float. If critical path activities are delayed, the overall completion of the project will be delayed.
What are milestones?
A project milestone is a task of zero duration that shows an important achievement in a project.
Please provide examples of typical programme milestones for a new build construction project?

What is the difference between a jagged and straight drop line on a programme?
Jagged drop line
Progress as a percentage is entered for each task. This shows activities which are on, behind or ahead on reporting date (as indicated by the red jagged line).
Straight drop line
After progress is entered, the programme is rescheduled so each task sits on the progress reporting date (this straightens the drop line). Useful to determine the impact on the critical path.
How would you put together a programme for a new project?
I would first understand the purpose of the programme and the level of detail reguired.
Identify all activities to be completed, project deliverables, contractual requirements and key milestones (consulting with the project team and stakeholders where required).
Assign durations to each activity.
Summarise activities into RIBA Stages.
Identify relationships between activities and link accordingly.
Identify float & critical path in the programme.
Issue the programme to the team for comment, adjust as required.
Monitor and review.
What is a concurrent delay?
Two or more delays caused by different parties occur independently of each other, but during the same period.
