II.1.4) Short description
Scottish Water is seeking to establish a multi-supplier Framework Agreement for the provision of Motor Control Centres (MCCs), Instrumentation, Control and Automation (ICA), Systems Integration (SI) and ICA maintenance and support services. The Framework will provide a flexible, scalable and resilient route to market for electrical, control, automation and Operational Technology (OT) requirements across Scottish Water's water and wastewater assets, supporting capital delivery, asset renewal and operational requirements.
The Framework will be divided into three Lots, with multiple suppliers appointed to each Lot: Lot 1 – Integrated MCC, ICA and Systems Integration; Lot 2 – Systems Integration and Automation Services; and Lot 3 – ICA Maintenance, Minor Works and Support. Suppliers may apply for one, several or all Lots. Depending on the nature, value, complexity and risk of each requirement, call-offs may be for fully integrated end-to-end solutions, standalone equipment supply or discrete specialist services. The Framework will be available for use by Scottish Water and its appointed Delivery Vehicles.
Call-off contracts may be awarded by direct award or by mini-competition between the suppliers appointed to the relevant Lot(s), in accordance with the Framework Agreement. Scottish Water gives no guarantee of the volume or value of work to be called off under the Framework or any Lot. The estimated value stated in the Contract Notice is the maximum anticipated value over the full Framework term and is indicative only.
The Framework will be based on NEC4 terms. Call-off contracts may be placed under the NEC4 Professional Service Short Contract, the NEC4 Engineering and Construction Short Contract or Scottish Water Purchase Order Conditions, as appropriate to the requirement and Lot being engaged.
Suppliers must maintain all relevant certifications, standards and regulatory compliance throughout the Framework term. MCC assemblies must comply with the current edition of the BS EN IEC 61439 series, including Parts 1 and 2. As a designated Operator of Essential Services, Scottish Water will require suppliers to support its obligations under the Network and Information Systems (NIS) Regulations, including secure-by-design engineering, OT cyber security controls, vulnerability management, personnel assurance and cyber assurance activities. Suppliers must be able to work safely within live operational environments forming part of Critical National Infrastructure, and bidders will be assessed on their capability to undertake the relevant CDM duty holder role(s) for each Lot.
Scottish Water is seeking suppliers who will work collaboratively as long-term delivery partners, including early engagement in project development, design and buildability reviews, accurate lead time and pipeline information, and support for standardisation, innovation, whole-life value and carbon reduction. Performance will be managed through key performance indicators, regular reporting and continuous improvement.
It is estimated the Framework Agreement will start in April 2027 and run for an initial term of 6 years. Scottish Water may extend it by up to 3 further periods of 2 years each. The maximum duration, including all extensions, is 12 years, ending March 2039. Scottish Water may use each extension at its discretion, depending on supplier performance, continued value for money and business needs.

VI.3) Additional information
The maximum framework duration of 12 years (comprising an initial 6-year term with three optional 2-year extensions) is justified by the nature of the requirement and the characteristics of the market.
The initial term aligns with Scottish Water's SR27 investment period, while the extension options provide continuity into subsequent regulatory periods, avoiding disruption and re-procurement during the delivery of long-term capital investment programmes.
The Motor Control Centre (MCC) and Systems Integration market is characterised by supplier consolidation, skills shortages and limited specialist capacity. A longer-term framework provides suppliers with the certainty required to invest in manufacturing capability, specialist engineering resources, apprenticeships and skills development necessary to meet future demand.
MCC and Systems Integration services frequently sit on the critical path of capital delivery programmes. A long-term framework supports forward workload visibility, early supplier involvement and access to manufacturing capacity, helping to manage programme, resource and supply chain risks.
The framework is intended to support a long-term collaborative delivery model focused on standardisation, innovation, continuous improvement and the delivery of whole-life value. These benefits require sustained engagement and investment over an extended period and would be less likely to be realised through a shorter-term arrangement.
The services support operational technology associated with critical national infrastructure. Longer-term supplier relationships support continuity of technical knowledge, secure-by-design delivery practices and ongoing cyber resilience.
Scottish Water is not committed to the full 12-year term. Each extension is entirely discretionary and will only be exercised where supplier performance, value for money and prevailing market conditions continue to justify continuation of the framework.
Scottish Water considers that a framework duration exceeding 8 years is necessary to secure long-term market capacity, support supplier investment, maintain continuity of critical operational technology services and enable the efficient delivery of long-term capital investment programmes.
