HS2 Main Works S1 & S2 - WP148.5_Noise Barriers (Doors)

The scope for this package is the supply and installation of six (6) no. sound-insulated doors, frames and fixings required for the proposed precast reinforced-concrete noise barrier structure to be installed by SCS JV as part of the works it is undertaking on behalf of HS2 for the S1 and S2 sectors of the main civil engineering tranche of HS2 Phase One. The proposed noise barrier structure is to be installed by SCS JV either side of the HS2 trace along the West Ruislip Retained Embankment and the Gatemead Embankment. The frames are to be fitted on site and fixed to the barrier only on the vertical edges, to allow the movement of the adjoining barriers that join centrally above the door (see the drawing with the reference ending 864102 attached to this CompeteFor opportunity). The doors must comply with the acoustic requirements in the 'Specification and SCEW Appendices' document attached to this CompeteFor opportunity, offer a 60-year life (with associated maintenance) and be suitable to resist the loads imposed upon them by the high-speed trains. The doors shall be replaceable at the end of their 60-year life cycle.

To assist you in determining whether or not this opportunity is of interest to your company, please find attached the following:

• Ruislip Noise Barriers Architectural Drawing Sections, axonometrics and visualisation (1MC04-SCJ_SDH-AR-DPH-SS05_SL07-869000).
• Ruislip Noise Barriers Engineering Structural Drawing Noise Barriers, Torsion Beams, Piles Details 2 (1MC04-SCJ_SDH-ST-DDE-SS05_SL07-864102).
• Specification and SCEW Appendices - Noise Barriers S2 (1MC04-SCJ_SDH-DS-SPE-SS05_SL07-000008).

Following responses to this opportunity, the supply chain will be shortlisted accordingly. Those that are successful will be invited to prequalify in order to receive a tender enquiry for this package. Prequalification will consist of 'business assurance', which will focus on the supply chain's capability, competence and capacity to work with SCS JV, and (potentially) technical assurance, which provides an opportunity to assess the supply chain's ability to provide the goods and services for the package in question. It is likely that this has been classified as a 'medium-risk' package (to be confirmed), whereby the 'business assurance' element of prequalification may be satisfied if the supply chain partner holds one of the Common Assessment Standard (CAS) accreditations, namely:

• Achilles Building Confidence (with Desktop Audit),
• Constructionline Gold, or
• CHAS Elite.

Further to a tender process, final selection will be based upon a balanced-scorecard evaluation. The criteria of this evaluation will consider commercial, technical and qualitative (e.g. health & safety, quality, environment & sustainability, etc.) evidence provided by the tenderers as part of their respective tender bids.

SCS JV is an unincorporated joint venture between Skanska Construction UK Limited ("Skanska"), Costain Limited ("Costain") and STRABAG AG ("STRABAG") working on behalf of HS2 to deliver the main civil engineering works for the S1 and S2 sectors of HS2 Phase One. The Early Contractor Involvement (ECI) stage of the contract, where SCS JV was developing a scheme design, programme and target cost to deliver the detailed design and construction phase of the project, is now complete, whereby a Notice to Proceed to Stage Two (detailed design and construction) was issued on 15th April 2020. Not only have the individual companies delivered high-speed rail, major infrastructure and some of the most iconic structures internationally, SCS JV also has a proven record of working together. Skanska and Costain have a long history of successfully delivering civil engineering projects together in the UK, dating back 30 years. In joint venture they have delivered many major infrastructure projects, including the M25 in the 1980s, High Speed 1 in the early 2000s and the current Crossrail endeavour, shortly coming to completion under the streets of London. STRABAG and Skanska have worked together for over 15 years on European projects in Switzerland, Slovakia and Norway. As a joint venture, we are bringing together our collective strength to deliver world-class engineering, contributing to the long-term economic growth of local and international markets. This is perfectly encapsulated in our mission; to draw everyone together to create a strong foundation from which to launch a transformative legacy.

Key points of contact, quality assurance and site management will be required. Site staff will also need to have the full CSCS and HS2/SCS JV on-boarding requirements. There will also need to be an element of design assurance to demonstrate that the fixings are suitable to fix the frame to the structure, and the frame suitable to flex with the movement of the panels without hindering the use of the door.
