Level 3 - Programming and Planning Flashcards
N 1. What is PERT?
Programme, Evaluation, and Review Technique
You create three estimates for the duration of a project,
- The most Optimistic (Shortest)
- The most pessimistic (Longest)
- The most likely (an average of the two)
N 2. What is a Project Programme?
A sequence in which tasks must be carried out to ensure a project can be completed on time.
N 3. What can be identified from the project programme?
- The overall Start Date.
- The overall Completion Date.
- The start date for each activity.
- The completion date of each activity.
- The amount of ‘Float’ each activity has.
- The Critical Path.
- Tasks which can only be carried out sequentially.
- Tasks which can be carried out simultaneously.
N 4. What should a programme help you do?
- Plan Activities.
- Monitor progress.
- Manage Resources.
N 5. What types of Programme are there?
- Contractors Master Programme.
- Clients Overall Programme.
- Design Programme.
- Information Release Schedule.
N 6. What goes into the Clients Overall Programme?
- Everything, from the appointment of the consultant, through to the completion of the project.
- This will include work outside the scope of the main-contractor.
N 7. What goes into the design Programme?
• It describes the sequence of design tasks, i.e. from the process of design from inception through the Technical Design.
N 8. What goes into an information release schedule?
- The dates by which information needs to be released by the design team, to avoid any delays.
- This works both ways, for example when the contractor has a Contactors Design Portion.
N 9. What goes into the Contractors Master Programme?
• The schedule and sequence of construction activities.
N 10. Can you employ a consultant to produce a programme?
• Yes, on large projects they can prepare the outline programme.
N 11. What should you consider when preparing a programme?
- Items with a long lead-in.
- Pre-contract works.
- Pre-fabrication elements.
- Works outside of the main contract.
- Relationships with other projects.
- Phasing and Sectional Completion.
- CDM Planning Period.
N 12. What is the CDM planning period?
• An amount of time given to the contractor, with the intention of allowing contractors to assess Health and Safety issues and plan their works before construction commences.
N 13. How long is the CDM planning period?
• Not specified, it should be proportional to the size and complexity of the project and the risk.
N 14. What is a Flow diagram?
• A Graphical representation of a process of steps/sequences required to achieve an end goal.
N 15. What is the benefit of using a Flow Diagram?
• It helps the team to understand the different processes and relationships between activities.
N 16. What is an Activity Schedule?
• A list of activities which outlines the works required to complete a project/package etc.
N 17. What type of contract uses an Activity Schedule?
• A simple project with few activities.
N 18. What type of contract uses an Activity Schedule?
• New Engineering Contracts, Engineering and Construction Contract Options A and C.
N 19. How is an activity schedule represented graphically on a programme?
- Typically using a Gantt chart.
- Each activity gets a bar.
- With a separate bar for preliminaries.
N 20. What should a PM do when receiving a contractors programme?
• Check that it is not front loaded.
- Check the activity timescales are reasonable and realistic
N 21. What is a Gantt chart?
• A way of displaying a programme, through a combination of bars, each relating to an activity and having a specified duration.
N 22. What does a Gantt chart programme show?
The: o Start Date. o Duration. o Completion date. o Of both activities and the project as a whole.
N 23. What are the advantages of a Gantt chart?
- Suitable for smaller projects.
- It is suitable for construction as it offers a high level of detail.
- To detailed for cost planning and estimates.
- It shows the times to scale.
N 24. What is the critical path?
- The shortest sequence in which a project can be completed in.
- It is also considered to be the projects bottleneck.
N 25. What is Critical Path Analysis?
• A way of analysing the programme, to see if the critical path duration can be shortened or activities on it altered.
N 26. What do you aim to identify when undertaking a Critical Path Analysis?
- Any items with slack float which can be used to improve the programmes critical path.
- Identify the risky items within the programme, i.e. items on the critical path that also have significantly long lead-in-times on materials etc.
N 27. What is a Key Milestone?
• Specific points along the programme used to measure progress.
N 28. What is the benefit of having Key Milestones?
Helps the project keep site of:
o The key dates.
o The Key Deadlines.
N 29. What is Float?
• The amount of time an activity can be delayed, before it impacts on the completion of the works.
N 30. Can tasks on the Critical Path have float?
• No, if they did you would identify them through Critical Path Analysis and amend the programme.
N 31. What are the types of Float?
- Total Float.
* Free Float.
N 32. What is Total Float?
• The amount of time an activity can be delayed, before it impacts on the overall completion date.
N 33. What is Free Float?
• The amount of time an activity can be delayed, before it impacts on the start date of another activity.
N 34. What valuation method gives the most accurate cash flow forecast in terms of time and surety of value?
• Stage Payments.
N 35. What are Stage Payments?
• Payment which are made in instalments, but do not necessarily reflect the value of work completed.
N 36. What is the most inaccurate in terms of time and value?
• Third party certification.
N 37. How can you monitor progress on site?
- Compare progress to programme.
- Compare Valuations against cash flow forecast.
- Use the ‘S’ curve principles.
- Milestone Chart.
N 38. What does PEP stand for?
• Project Execution Plan.
N 39. What does a Project Execution Plan Do?
• Sets out the strategy for managing a project, by defining who does what, and how.
N 40. What might be included within an Project Execution Plan?
- The Project brief.
- The drawings.
- The Procurement Strategy.
- The Programme.
- The Risk Assessments and Methods Statements.
- The Health and Safety Strategy.
- The Quality Assurance Policy.
N 41. What does ISO Stand for?
• Internal Standards Organisation.
N 42. What is the benefit of having ISO?
• It will imply that the product/organisations services are safe, reliable and good quality.
N 43. What ISO Standards do you know of?
- ISO 9001.
* ISO 14001.
N 44. What is ISO 9001?
• A Quality Management system, used by organisations who want to prove that they consistently meet the needs of their clients.
N 45. What is ISO 14001?
• An Environmental Management System, used by organisations who want to prove they consistently consider the environment in their field of work.
N 46. CASE LAW QUESTION: CAN YOU TELL ME ABOUT ANY CASE LAW RELATING TO PROGRAMMES?
- Yes, Cleveland Bridge UK V Severfield Rowen Structures Ltd.
- Cleveland Bridge made and supplied the steel work for the shard, which was installed by Severfield Rowen.
- CBUK couldn’t keep up with the fabrication of the steel.
- SRS had to extend working hours on site to keep up to programme.
- CBUK claimed that SRS held up fabrication due to late instructions and variations.
- SRS claimed counter claimed on the basis of the cost of accelerating, defects in fabrication and losses due to the delay.
- Issue was that there was no contractually agreed programme.
- Judge decision was for both parties to pay almost equal damages to each other.
N 47. What are the Three types of delay?
- Contract Led.
- Client Led.
- Neutral.
N 48. What is Concurrent delay?
• Where multiple delays for numerous causes overlap. The difficulty is in determining the root cause.
N 49. What types of concurrent delay are there?
- Parallel Fault.
- Overlapping Events.
- Truly Concurrent Events.
N 50. How do you assess Concurrent Delay?
• You must determine the root cause, true concurrent delay is actually very rare.
• Once you determine the root cause, you should really discard any other delays.
• Use the Malmaison approach.
o This is where if it is considered that one of the delays is the clients risks, then the contractor should be entitled to a Extension of Time without loss and expense.
o It will have to claim for loss and expense separately.
N 51. CASE LAW QUESTION: DO YOU KNOW OF ANY CASE LAW RELATING TO CONCURRENT DELAY
- Yes, Balfour Beatty v Chestermount properties Ltd.
- Balfour Beatty were late in completing the works.
- Clients issues and instruction to undertake the fit out.
- Balfour try to use the variation as a reason for covering the late delivery.
- Client ignores the instruction and tries to claim LAD’s.
- Judge rules that the actual completion date should be the amount of time required to complete the fit out, added onto the completion date of the original works.
