Challenges

Delivery of projects on ‘live’ electricity substations is a key challenge. We've developed and implemented schedule assurance which has brought together the key disciplines within the project team to understand and achieve ‘sign off’ of schedules. This procedure obtains ‘buy in’ from all elements of the project and ensures scope can be delivered without compromising safety or substation operations.

National Grid is closely regulated and our planning management team instigate regular project peer reviews with each of the planners in the team. This ensures that best planning practice is applied and that we are compliant with operating procedures.

The alliance brings together three large companies who have different requirements from the schedules. We engage each of the partner companies to ensure that the schedule contains robust information which is issued to the partners, but which also gives one message when communicating with the client.

Our planning management team hold audits on projects to ensure the project teams are complying with client instructions relating to earned value management. These reviews ensure that the methodology for claiming progress is clear and is demonstrable to the client.

Value and benefits

We've introduced integrated schedules for several key substations to show the positive cost effect of undertaking asset replacements simultaneously. Due to the nature of how the funding was instructed (asset by asset) we were able to demonstrate savings on items such as bulk procurement, mobilisation and so forth.

We have been running analyses at project level where key milestones are at risk, alerting the management team where recovery plans are required.

We produce schedule assumption reports in accordance with the schedule assurance procedure. These enable project team members and National Grid’s cost assurance function to clearly understand decisions relating to duration and sequencing of tasks.
