    TENDER DESCRIPTION

    This tender seeks expert Naval Architecture and Marine Engineering services to provide comprehensive technical support for the Scottish Government's Vessel Replacement Project, encompassing new Multi-Purpose Vessels (MPV) and Marine Research Vessels (MRV). The scope includes pre-contract procurement and negotiation support, post-contract build, design approval, site supervision, factory and vessel trials, and acceptance activities, with fixed pricing for these phases and a rate card for potential ad-hoc requests. Key deliverables involve design review (estimated 200 reports), provision of specialist supervision personnel throughout construction, and full participation in trials, all underpinned by robust technical assurance frameworks and structured risk management. Bidders must meet financial standing requirements including an average annual turnover of at least £6 million over the last three years, a current ratio greater than 0.8, and a Dun & Bradstreet 'Failure Score' of 51 or above, with submissions processed via the PCS-Tender platform. The contract will run from a specified commencement date to an initial expiry date, with potential for extension to a longstop expiry date,…

    TENDER BRIEF

    The contract timeline indicates a "Commencement Date" and an "initial expiry date", with the possibility of extension to a "longstop expiry date". No specific dates are provided, as they are represented by placeholders (e.g., «commencement date», «initial expiry date», «longstop expiry date»). The contract also includes "Milestones" which are events or tasks that must be completed by a particular date and are tied to the successful delivery of Deliverables, and payment is based on their completion.

    The core scope of work for this tender involves providing expert technical and naval architecture support for a Vessel Replacement Project, specifically for new Multi-Purpose Vessels (MPV) and Medium-Range Vessels (MRV). The Service Provider is expected to understand Marine Directorate’s concept designs for these vessels and have the capacity to deliver services across a potentially two-lot procurement and build process running concurrently.

    The Statement of Work (SOW) summary and core deliverables can be broken down into three main parts:

    Part A: Procurement & Negotiation Support (Pre-contract award)

    • Evaluation of shipyard bids at each stage of the negotiated procedure process.
    • Participation in evaluation panels for discussions and moderation.
    • Input into preparation and attendance at negotiation sessions.
    • Handling technical clarifications.
    • Assisting the project team in understanding technical risks.
    • Supporting risk allocation and incentivization decisions.
    • Working with legal and commercial advisers to ensure negotiations deliver the best outcome and comply with applicable laws.
    • Providing advice on technical aspects of the contract and any review processes.
    • Explaining the rationale behind preferred technical solutions and assessing implications of proposed design choices.
    • Advising on alternative proposals or value engineering.
    • Supporting decision-making prior to contract award.

    Part B: Build, Design Approval, Support, Supervision & Acceptance (Post-contract award)

    • Providing technical input and supervision during the design stages of the design and build contract.
    • Monthly attendance during the build phase by Naval Architecture Staff (not supervision staff).
    • Review of design submissions, changes, and deviations (bidders should price based on review of 200 reports).
    • Attendance at Factory Acceptance Tests.
    • Full participation in trials and final acceptance, envisioned as one week of harbor and one week of sea trials.
    • Provision of suitably qualified staff for yard-based supervision throughout the build, including a Lead site supervisor (from steel cutting to delivery), Steelwork supervisor (from steel cutting to launch), Machinery engineer (from main engine installation through delivery), and an Electrical Engineer (2-3 times a month).
    • Support during steel fabrication, machinery installation, and electrical installation.
    • Review of planning approvals submitted by the shipyard in consultation with the Marine Directorate.
    • Providing input into acceptance criteria and reviewing plans and drawings with recommendations to the Marine Directorate.
    • Advising on compliance with class, flag, regulatory, and environmental requirements.
    • Supporting early design assurance (drawing and equipment reviews).
    • Advising on readiness for major milestones.

    Part C: Ad-Hoc Requests

    • The Consultant shall provide a rate card for Junior Engineer, Engineer, Senior Engineer, and Principal Consultant for requirements that may emerge during the project.
    • These requests will be commissioned through a separate Statement of Work (SOW) process, agreed upon in writing between the Service Provider and the Marine Directorate.

    Fixed prices will apply to Parts A and B, which include the review and update of existing concept design packages, technical specifications, and associated deliverables. Ad-hoc services (Part C) will be charged via a rate card.
