What is a programme?
Sequence of events
What does a project programme identify?
Benefits of Programmes
a) plan activities
b) monitor progress
c) manage resources
Types of programme
Consideration when preparing a programme
Items with a long lead in
Pre-contract works
Pre-fab elements
Works outside the main contract
Relationships with other projects
CDM Planning period
What is a Gantt chart?
A way of displaying programme, through a combination of bars each relating to an activity of a specified duration.
What is a flow diagram?
A graphical representation of a process of steps/sequences required to achieve an end goals. Helps the team to understand the different process and relationships between activities.
What is an activity schedule?
A list of activities which outlines the works required to complete a project. Used for simple projects with few activities, usually presented as a gantt chart.
Float?
The amount of time an activity can be delayed without delaying the subsequent activity of critical path
Types of float: Time Float?
Time an activity can be delayed without delaying the planned completion date
Time Risk Allowance?
Duration allowed in each activity by the contractor to account for the risk of not completion
Critical Path?
The longest sequence of activities in a project which must be completed
Programme Acceleration?
Moving a project closer to completion date at a faster pace than planned, to either complete the works prior to original completion date.
Risks of Programme Acceleration?
When developing a master programme for a client, what should be considered?
EOT Analysis Types
Planned Impact
Time Impact
Time slice window analysis
Collapsed as built analysis
EOT: Planned impact
Introducing a delay even sub-network into the baseline programme, needs to be logic linked.
Y: Simple, cheap
N: Doesn’t consider actual progress and changes to the original programme
EOT: Time Impact Analysis
Introducing a delay event sub-network into updated programme, needs to be logic linked
Y: Simple/inexpensive
N: Doesn’t capture eventual delay as subsequent project progress is not considered.
EOT: Time slice
Updated programme, progress of works divided into time slices, actual critical path.
Y: More sophisticated view on delay, removes complexities of reviewing project as a whole
N: Only done retrospectively, more specialist analysis
PERT?
Programme, Evaluation, Review Technique: Creating 3 estimates for the duration of a project.
What is dependency in programme?
Where a task or activity is reliant on another task/activity to complete before it can start?
How to get from one RIBA stage to the next?
Stage gate approvals: client sign off key deliverables within the stage
Types of logic links within a programme
What is the CDM Planning Period?
An amount of time given to the contractor, with the intention of allowing contractors to asses H&S issues and plan their works before construction commences
