HS2 Main Works S1 & S2 - LOD5 Integrator - Design Coordination

LOD 5 Integrator - Outline scope of Work

SCS Railways has progressed the design of the London Tunnels and associated assets in Area West to the stage of LOD 4 for most of the assets involved. The LOD 4 designs have been developed by the SCS Railways consultant DH, a joint venture between Arup, Typsa and Strabag.

The work that we are currently coming to market for is the overall co-ordination of LOD 5 designs including architecture, structure and M&E (who will have their own co-ordinator) into a coherent whole in BIM (in compliance with project BEP). The assets included are 2 shafts, 4 headhouses, an entrance portal and various urban landscape elements including site boundaries and all aspects related to a complete fully integrated as built product for handover to High Speed 2.

The integrator is expected to provide following services:

• Review LOD4 designs and carry out a design optimisation and standardisation process to maximise Procurement, Buildability, Operability and Maintainability. This will include (but not limited to) elements such as promoting offsite fabrication, standardise M&E elements in discussions with the M&E co-ordinator, standardisation of stairs, doors etc. In doing this task, coordinator is expected to ensure that the environmental impact of the designs is minimised. • Coordinate multidisciplinary BIM and ensure that all LOD5 designs have been included in the model for clash detection, and handover to HS2. • Interface with the Design House and SCS LoD 5 designers including attending meetings. • Provide support in responding to TQs/RFIs. • Provide support in assurance of LOD 5 designs and then in handover to HS2. • Interface with all parties involved to develop commonality of function, space proofing, specification and detail, mainly for design intent review and adherence. • Support in Design & Change management. • Management of architectural production information package inclusive of the urban Realm (including landscape architecture). • BIM & CAD Outsourcing and management. • Management of specialist sub-consultant's and sub-contractors BIM deliverables. • Asset data management and collection to produce COBie (or similar) deliverable. • Management of As Built information from sub-contractors and sub-consultants including COBie.

Duration - Approximately 3 years.

To assist you in determining whether or not this opportunity is of interest to your company, please find the following link to Adelaide Road Headhouse information (as an example of the assets that form this package): https://www.hs2.org.uk/in-your-area/local-community-webpages/hs2-in-camden/adelaide-road-headhouse-and-ventilation-shaft/

Your company must be able to demonstrate capacity and capability to undertake such works over the required period. 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. The procurement strategy of letting these works as an envelope package, by area or by cladding system are to be determined. Please express interest and confirm preferences and capabilities.
