A Contract Award Notice for the CHC/647 TIESE Contract. This is a single source contract for the provision of Engineering Support, Technical Documents, Repairs and Spares in respect of Chinook Platform's existing Troop Insertion & Extraction System Equipment (TIESE).
As IrvinGQ is the manufacturer of the TIESE system they are the only contractor capable of delivering the requirement, meaning a single source procedure prevailed over competition on technical grounds (further information on technical justification is found below):
IrvinGQ previously confirmed that it is not prepared to share or license the use of that proprietary information outside of the Company and the UK Ministry of Defence does not have a right to obtain the necessary documentation from IrvinGQ. The aforementioned skills, technical data, drawing and design information are necessary for the performance of the requirement. Furthermore, only IrvinGQ holds the level of certification (under the Authority's Design Approved Organisation (DAOS) and Maintenance Approved Organisation (MAOS) Schemes) necessary to carry out the activities that are required in order to meet the Military Aviation Authority's Regulatory Articles applicable to TIESE. It is not possible for another company to obtain the relevant level of certification without access to the skills, knowledge and technical information that only IrvinGQ hold.
