## Description
The current phase of the STEP programme (Tranche 1) concludes in April 2024 when, subject to approval, Tranche 2a will commence. This is the phase when STEP will develop from an embryonic programme with a concept design and a selected site, and contracted support; to a fully formed major programme bringing together and developing extensive industrial capabilities to deliver a full plant design, a viable supply chain and to seek the consents needed for construction.
STEP is looking for a Construction Partner that will be a full member of the Integrated Delivery Team and, in collaboration with the wider team and the STEP leadership, will help shape the design for constructability, evolve the construction strategy, develop site plans and ultimately manage and develop the STEP site through a major multi – project construction phase, ensuring highest standards of safety.
