What is being bought
This work package covers key enabling activities required to prepare the site for main construction. It includes the design (from RIBA 4 Stage) and delivery of, ground related enabling activities required to prepare the site for construction, including species relocation, remediation servies, site clearance, site establishment, construction utilities, and supporting infrastructure—such as drainage and haul roads to support bulk earthworks. Together, these early work establish correct ground levels, and create safe access rotes for subsequent phases, and will provide the foundational physical platform needed to de‑risk, mobilise, and accelerate the main works programme. GBE-N had previously considered spllitting these packages into two, but has decised to consolidate into one package to minimise interface risk. *The positions and timelines presented are based on current information and assumptions. As programme maturity develops and further validation is undertaken, scope, dates, values and sequencing may change.* Contract Value range: £730m-£1,100m
