The procurement involves designing a reliable safety system compliant with functional safety standards IEC 61508 and IEC 61511. The contract value is £65,000, with a tender deadline of 11th July 2023. The procurement method is an open procedure below threshold for construction-site supervision services. This tender by The Pirbright Institute presents an opportunity for businesses with expertise in construction-site supervision services, construction consultancy services, and consulting services for water-supply and waste consultancy. Small and medium enterprises (SMEs) are encouraged to participate in this procurement stage, which aims to enhance safety at the Pirbright site through the implementation of a safety-critical system. ## Notice Following a Layers of Protection Analysis (LOPA), The Pirbright Institute requires the design of a safety system that detects flooding of the drainage system in the building. The system subsequently responds by shutting down the building water supply system. As per Functional Safety standards IEC 61508 and IEC 61511, Pirbright requires this system to be reliable to Safety Integrity Level (SIL) 1. Safety Requirement System (SRS) attached at the back of this document for more detail. Pirbright expects that the designer will have good awareness of the above-mentioned functional safety standards, and to be able to carry out their activities in adherence to the functional safety lifecycle phases as per IEC 61511.
