The project is a key part of the first phase of the MetroWest programme of transport improvements across the region being led by the West of England Combined Authority and North Somerset Council.
The multidisciplinary project will involve 5.5km of new railway along a disused line between Pill and Portishead.
Works comprise detail design, surveys, environmental & ecology, civils, track, highways, buildings, telecoms, M&E and E&P.
It is proposed to use a target cost contract (NR12) for a single design and construct contract.
Network Rail is presently assuming railway control systems works are to be undertaken by other specialist contractors, but may include, subject to funding and consents, to include and award these works within the main build contract.
The reopening of the Portishead to Bristol line is hoped to solve the congestion gridlock faced by thousands of motorists who battle to get in and out of the growing town each day.
Under the procurement timetable expressions of interest are due in by June with four shortlisted firms due to be invited to tender in July.
