Early Works for the Lower Thames Crossing - North Portal and Tunnelling Spoil Disposal Services

The Lower Thames Crossing project comprises of two bored tunnels beneath the River Thames with interconnecting link roads to the M25, A13 and A2. At 16 metres in diameter, the tunnels will be some of the largest bored tunnels in the world. The crossing will feature three lanes in both directions with a maximum speed limit of 70mph.

At circa 2.4 miles each the tunnels will be the longest in the country. The tunnel's north portal site (the "North Portal") will be located on the north shore of the Thames east of the old Tilbury B Power station site and south of the Tilbury loop railway line. The north Portal structure and its approach ramp is to be constructed within a sizeable excavation. Approach roads to the North Portal construction continue at ground level north towards the proposed viaduct over the Tilbury loop railway line.

Highways England tested the market for interest by way of a PIN (2020/S 027-063332) ("PIN") and there was limited market interest and limited response rates to the PIN. All interested parties were invited to discuss their capabilities to provide the services described within this opportunity in a manner that is likely to be compliant with the proposed constraints of the Development Consent Order ("DCO") under a non-disclosure agreement. This process identified only one interested supplier who was able to demonstrate their capabilities and relevant skill and experience in performing the required services in a manner that was compliant with the likely obligations of the DCO. Highways England has therefore concluded that Ingrebourne Valley Limited ("IVL") are the only suitable supplier for receiving spoil arising from the North Portal and tunnels excavation and its subsequent disposal, and Highways England intend to award a contract to IVL for these services under Regulation 32(2)(b)(ii) of the Public Contracts Regulations 2015. Subsequently, a VEAT notice was issued (23/04/2021) informing the market of the Authorities intention to award directly to IVL the spoil disposal services (including any necessary early works the prepare the site for receipt of spoil prior to the DCO being granted). There were no challenges raised during the standstill period.

This contract award notice is in relation to the first of two contracts which together will cover the scope of the PIN. This notice relates to an award of a contract relating to an enabling works contract to allow site preparation necessary to prepare the site and to carry out the spoil disposal services to take place prior to the DCO being granted (this contract award (initial contract value of £572k with re-measurable items giving an outturn forecast of circa £1m). The second agreement relating to spoil disposal services shall be subject to a separate notice.
