Installation work of refrigeration equipment. Toxic waste disposal services except radioactive waste and contaminated soil. Removal, Build, and Installation work of refridgeration equipment, within the SSPAR (Solid State Phased Radar) Facility at RAF Fylingdales, which must be completed before end of March 2014. — Working to an infrastructure design and chiller outline specification provided by the authority, the bidder will be required to conduct: detailed design, manufacture, installation, testing and commissioning of liquid cooled chiller units capable of generating 6MW chilling capacity to replace the existing capacity currently provided by 3 x 2MW units. The configuration of the chillers should be such that they provide maximum resilience and flexibility. The project will include associated pipework, switchgear, controls and indicators, — The existing plinths are to be used where possible, — The entry and exit routes for the plant are exceptionally challenging requiring the new plant to be compact (detail to be provided as part of tender pack). The existing plant may need to be disassembled to allow recovery and disposal, — Additional plant required as a consequence of the chiller plant selected, such as pumps or filters shall form part of the bid, — The bidder will be responsible for the removal from site and disposal of all plant replaced, including refrigerant storage and replenishment facilities, and the R123 refrigerant used and stored on site, — The bidder must maintain a minimum of 3MW of chiller capacity throughout the build, — The current liquid cooled chiller units that are in use within the main radar building currently use HCFC-R123, contrary to the Montreal Protocol, which limits use of these HCFCs after Dec 2014. Any replacement units must meet with the latest EU legislation with regard to the use of ozone depleting and global warming substances.. In addition as part of this project there will be input/output points that are required for integration into the existing Building Management System, — All equipment supplied and installed must be capable of operating from a 416V, 60Hz, 3 phase electrical supply, — During the system installation the building will remain occupied on a 24/7 basis and must be fully operational with sufficient redundancy and cooling capacity to sustain the mission at all times, — There are overriding space limitations to and within the existing plant room, furthermore there must be no breach to external walls. It is anticipated that the maximum plant size length for access should not exceed 5 metres and pass through a 1.7m wide x 2.0m wide double door opening, — The completed system is to have a planned life of a minimum of 20 years therefore all system components are to have a low risk of obsolescence and must conform to an open standards format. All work must have risk assessments, method statements and must conform to the mandatory operational restraints, — Additionally the chiller plant component design is expected to give efficiency returns on the existing units and guaranteed compliance of any ozone depleting or global warming substances used for at least 20 years. Disposal of existing materials and substances must be certified in accordance with current legislation for disposal of any hazardous or banned substances, — Potential Bidders with experience of replacing and installing the aforementioned requirement should submit an expression of interest in writing, including evidence of relevant experience by 29 Nov 2012. The Authority is unable to consider late or incomplete expressions of interest, — Local planning, support and project management will be provided on site to liaise between contractors and site operational staff to procedurally ensure the smooth and seemless integration of the project whilst thus ensuring the availability of the capability at all times. RAF Fylingdales is a site which is subject to legislation contained in the Official Secrets Act. Therefore all Bidders will have to demonstrate that they can obtain NATO Secret Clearance.
