Project Design and Delivery: Utilising our deep understanding of NGET’s operational standards to support SSEN in meeting project timelines and overcoming technical challenges across ownership boundaries.
-
Process definition and mapping: production of process flow diagrams to articulate the requirements of the project to our client ensuring widespread knowledge of work flows, timescales, deliverables and authorisations, delivering structure and efficiency.
Outcome: Through Monui’s support, SSEN is successfully navigating the complexities of delivering NGET assets, ensuring adherence to all required processes and specifications, creating a a template for all future transmission network interface projects. This collaboration exemplifies our ability to bridge gaps between different organisations, fostering successful project outcomes and advancing the infrastructure for a more reliable energy network.
HURST SHUNT REACTOR 3 REPLACEMENT
Project Overview: Burns & McDonnell successfully tendered for a project on National Grid’s M&E Framework, involving the asset replacement of a 13kV Shunt Reactor and bund. The project included the demolition of the existing noise enclosure and the installation of new surge arrestors and a protection system.
Our Role: Monui was tasked with providing a Project Manager (PM) to Burns & McDonnell. The PM’s responsibilities included:
Direct Interface: Acting as the primary liaison with the National Grid PM to ensure smooth communication and coordination.
Contract and Works Management: Overseeing the contractual obligations and managing the project works.
Reporting: Providing regular updates to the Burns & McDonnell Senior PM managing the framework.
