What is being bought

Published requirement description

UKAEA are looking to engage a Supervisory Control And Data Acquisition (SCADA) specialist to develop a new SCADA system in J5 based on the IEC 61850 protocol, replacing the existing SCADA. The work includes the design, manufacture, delivery, installation, and commissioning of the complete system, including an operator workstation in J5 control room. The SCADA will provide full control authority in J5 and D8, with intelligent interlocking to prevent failures or operational errors. The system will integrate with all numerical and auxiliary devices, transmitting all alarms, trip signals, and status indications over fibre or Ethernet to the main control room. A GPS-synchronized clock will ensure accurate system timing. Additionally, a rugged firewall will be implemented to protect the system against cyber threats, ensuring secure and reliable operation.

What this means for your bid
  • Price carries 50 of 100 points: a 10% discount moves about 5 points. This one is won on the number: sharpen the price before polishing the prose.

Price arithmetic assumes straight proportional scoring; the tender pack may use another formula.
