Programming and Planning Flashcards
What are programmes used for
Planning and monitoring the progress of projects
. Strategic, design, construction
. Communication tool
. Cash flows
What are key principles of an effective programme
. Clear and well communicated
. Accurate (regularly checked and updated)
what is the critical path
Determines the shortest possible route to completion (sequence of necessary, and dependent, tasks)
. Any delay would delay overall completion
What diff programme types are there
Gantt
PERT
How did you monitor construction programme
.Site visits with a programme in hand, marking it up as i go
. Check against it each time
How do you create a programme
. Understand Activities
. Understand durations
. Plot dependencies
. Plot on a graph (gantt)
Takes team input and previous experience
what is float? What are the types of float?
Float is the time between completion of an activity before the next activity is impacted
. free float, between activities
. Total float, from critical path to PC
. Terminal float, from PC to contract PC
How do you get the team to buy in to a design programme
Try to ensure periods are acceptable beforehand
.The discuss with them, listening to any quarms but ensuring they understand client drivers
How did you accelerate programme? What were implications?
NF CAT B
. Split work into packages: CAT B then FF&E
. Means one can get underway whilst design goes on with another
. Can lead to more rushed design/less coordinated/cant make changes to suit later design decisions
How did brief changes impact programme?
As assumptions had been made by design team, where these were incorrect, changes to design were necessary
what is a forward pass
calculates earliest start and earliest finish dates
Start (0), adding duration for each activity, ensuring dependencies can only start when other task has finished)
what is a backwards pass
After forwards pass, can go back to work out the latest possible start and finish times, the difference between forward pass and float is float.
what is a PERT
Programme Evaluation and Review Technique
. Helps estimate durations by looking at Optimistic, Most likely and Pessimistic
. Helps to identify critical path
Consists of nodes, arrows to show dependency, and time estimates (one for each: O,M or P)
who owns float
Depends on contract terms, often contractor
what is earned value analysis?
Compares planned progress vs actual progress. can show variances on progress and cost
Planned Value
earned value
actual cost
EV - AC shows over or under budget
EV-PV shows programme variance
EV/AC shows cost performance
EV/PV shows programme efficiency
What role do programmes play in different contract types?
JCT = fixed programme. Only rlly used for monitoring. Any canges require formal agreement (EOTs)
NEC= collaborative. live, flexible. programme key to early warning systems.
What software can be used for programming
Asta, primavera, excel
What is a works breakdown structure
breakdown of all activities, into more manageable groups. makes managing big projects easier
what is critical path method
longest sequence of tasks that must be completed - shows minimum time required to complete project
focusses on critical items, prioritising these and those it is dependent on
How can you accelerate programme?
increase resource, package works, re-sequence
How can you increase resource?
weekend/OOH, more people
What is an EOT? What does it include?
.Reason for delay,
.evidence
.impact
.new completion date
. mitigation measures
What does a gantt look like
.2 axis: time, activity
. bars represent each activity
. Easy to understand
. Duration is clear, dependencies are clear
