Programme and Planning Level 2
Level 1 Hooks
Critical Path
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
Float
Total float
- The time an activity can be delayed from its early start date without delaying planned completion. Available either to the employer or contractor (on a first come first served basis)
Free Float
- “free float” is used to describe amount of time that spans from the completion of one previously scheduled activity and extends to the point at which the next scheduled activity is set to begin. Free float can be calculated by determining the amount of the time between the earliest start date of the initial activity and the earliest start date of the succeeding activity, and then subtracting from that total the amount of time that it is expected the first activity will take to complete. During this period of free float, the completion time or date of the earlier of the activities can be extended up until the scheduled early start date or time of the next scheduled activity without causing delays. If there is no succeeding activity scheduled, the project end date would be used to determine the back end of the free float window.
Woodwharf - Programme
Master Programme
How would you put together a programme of works?
1) First understand the purpose of the programme and the level of detail required
2) Identify all activities to be completed, project deliverables, contractual requirements and key milestones
3) Assign durations to each activity
4) Summarise activities into RIBA stages
5) identify relationships between activities and link accordingly
6) Identify float & critical path in the programme
7) issue the programme to the team for comment, adjust as required
8) Monitor and review
Droplines
Straight drop line
- After progress is entered, the programme is rescheduled so each task sits on the progress reporting date. This is useful to determine the impact on the critical path
Jagged drop line
- Progress as a percentage is entered for each task. This shows activities which are on, behind or ahead on reporting date
Critical Path analysis
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
Identify and list all the tasks associated with the project. This includes listing every deliverable that will be required.
Separate the critical tasks from the non-critical ones.
Place the critical tasks in sequential order, noting all dependencies.
Determine the earliest start date, latest start date, earliest finish date, and latest finish date for each critical task.
Cobalt - D&B programme
Design & Build procurement route
Why was a D&B route adopted?
The client had time constraints of getting the tenant into the space by a certain date
The client did not have much experience in construction projects
The client wanted to transfer as much risk as possible to the contractors
RIBA stages 2-4
Stage 2 Concept design - Architectural Concept approved by the client and aligned to the Project Brief
Prepare Architectural Concept incorporating Strategic Engineering requirements and aligned to Cost Plan, Project Strategies and Outline Specification
Agree Project Brief Derogations (exemptions)
Undertake Design Reviews with client and Project Stakeholders
Prepare stage Design Programme
Stage 3 Spatial Coordination - Architectural and engineering information Spatially Coordinated
Undertake Design Studies, Engineering Analysis and Cost Exercises to test Architectural Concept resulting in Spatially Coordinated design aligned to updated Cost Plan, Project Strategies and Outline Specification
Initiate Change Control Procedures
Prepare stage Design Programme
Stage 4 Technical design - All design information required to manufacture and construct the project completed
Develop architectural and engineering technical design
Prepare and coordinate design team Building Systems information
Prepare and integrate specialist subcontractor Building Systems information
Prepare stage Design Programme
Technical information tracker
An example of this would be identifying what the occupancy schedule for the building is so that the design engineer can ensure the HVAC system being designed is adequate for the amount of people that will be in the space
This is a tracker that highlights all of the technical information required to progress the design
Work breakdown structure
A work breakdown structure (WBS) visually organizes project deliverables into different levels based on dependencies. It’s essentially your project plan in a visual form, with your project objective at the top, then dependencies and sub-dependencies below.
Example
Level 1 - Construction Phase
Level 2 - Area of works
Level 3 - Discipline i.e. M&E
Level 4 - Work Package i.e. Electrical, HVAC, Mechanical, BMS
Outstanding information
Tangible examples
MEP
Trade and cooperate network requirements for each outlet within the space
List of IT room equipment dictate the heating output for the AC system to be adequately sized
Security requirements within the space which will dictate where CCTV cameras are to be installed and also what door are to be accessed controlled.
Furniture
What furniture was going to be new or reused
Dimensions of the reuse furniture
Weight was the weight of the reuse furniture (for requirements of localised flooring supports)
