Air quality management

Tender description

The Council invites tender bids for the supply of products and services to ensure the running of Glasgow’s air monitoring units. The framework is expected to run for 3 years, commencing November 2018 and ending on November 2021. The Council will have an option to extend the contract for a period of up to 12 months which will be exercised by the Council serving notice on the bidder in accordance with the Council’s terms and conditions. Lots The tender has been allocated into 3 separate lots and they are as follows: Lot 1: Service and Maintenance of Air Monitoring Instrumentation; Lot 2: Service and Maintenance of Air Conditioning Units; Lot 3: Supply, Delivery and Installation of Air Monitoring Equipment. Equipment shall be serviced and maintained in accordance with the manufacturer’s recommendations and compliant with current/future regulations. All spare parts and consumables used in the network shall be either manufacturer’s original parts, manufacturer approved and are of manufacturer’s warranty as a minimum. The supplier will be required to conduct 1 x planned service visit per annum. All repairs will generally be conducted Monday – Friday between the hours of 9.00-17.00. Any requests to attend and conduct repairs or maintenance on Saturday or Sunday must be requested and agreed with GCC. Supplier must email GCC within 24 hours of any repairs on site to confirm status of repairs and must provide follow up report within 7 days appointed service provider must hold FGAS certificate; If the appointed supplier is unable to obtain parts for repair of equipment, provision of suitable ‘type alternative’ equipment may be considered but must be at no additional cost to GCC. This will not be accepted without prior written agreement from GCC. It is envisaged that any new air conditioning units purchased during the life of the framework agreement, will be absorbed in to the Council’s existing service and maintenance agreement. Glasgow City Council, with assistance from the Scottish Governments LAQM funding support, operates a network of automatic air quality monitoring stations. Monitoring data from Glasgow’s air quality stations is used in the assessment of air quality across the city; the monitoring stations are operated in accordance with guidance provided by the Department for Environment, Food and Rural Affairs (DEFRA). Pollutants presently monitored include oxides of nitrogen (NOX), Ozone (O3) and Particulates at PM10 and PM2.5. Whilst not currently monitored, the pollutants sulphur dioxide (SO2) and carbon monoxide (CO) have also been monitored in recent times. Tenders bids are invited from companies with the relevant technical expertise, resources and access to suitably certified instruments for the supply, delivery and installation of air quality monitoring instruments. Specification Glasgow’s air quality stations are operated in accordance with guidance provided by the Department for Environment, Food and Rural Affairs (DEFRA). The current technical guidance document, LAQM Technical Guidance 2016 (TG16) stipulates that only instrumentation with MCERTS (Environment Agencies Monitoring Certification Scheme) approval for Continuous ambient Air Monitoring Systems (CAMS) can be used in these stations when monitoring for compliance with the relevant air quality objectives. Equipment presently in use and which may be supplemented/replaced as required includes: Chemiluminescent NO/NO2/NOx Analyser (reference method). U.V. Photometric Ozone Analyser (reference method) Particulates at PM10 by Filter Dynamic Measurement System Tapered Element Oscillating Microbalance (FDMS TEOM), Tapered Element Oscillating Microbalance (TEOM) and FIDAS Particulates at PM2.5 by FIDAS (Optical Light Scattering). Instruments will be rack mounted and must be compatible with existing operation parameters i.e. stations are unmanned with remote access to data and instrument parameters. Calibration. Gas analysers are routinely calibrated using external scrubber/zero air certified external gas and certified concentration external gas cylinders; there is therefore no requirement for the provision of internal zero/span assembly. Communications GCC AQ monitoring stations currently use Weblogger (Gen2) as a data logger, communication and control system compatibility with this hardware is a mandatory requirement. Warranty Whilst instruments will be absorbed into the Council’s existing routine service and maintenance contract (Lot 1). Responsibility for the identification and repair of faults within the warranty period remains with the service provider. This requirement will extend to the provision of replacement instruments as required. Purchase of equipment Please note that any instruments required to be purchased via this lot will be done so via mini competition process. All suppliers on this lot will be invited to tender and will be supplied with a fully detailed specification and pricing schedule. Equipment shall be serviced and maintained in accordance with the manufacturer’s recommendations and best practise guidelines compliant with current/future regulations and now LAQM TG(16). The supplier will be required to conduct 2 x planned service visits per annum. For any off site repairs on equipment, supplier will be responsible for uplift and delivery once equipment is fixed; Provision of suitable ‘type alternative’ equipment at no additional cost to GCC may be carried out only with prior written agreement from GCC. Supplier must email GCC within 24 hours of any repairs on site to confirm status of repairs and must provide follow up report within 7 days. All repairs must be carried out within 7 days of initial notification. Contractors staff must have formal training on all equipment in Glasgow’s air quality monitoring network and, where possible, manufacturer’s supplied training. The supplier will be required to provide evidence of this as and when requested by the Council. Appointed supplier will be expected to stock Council sites with local site operator consumables in advance of the Council conducting site visits pre-stock at beginning of contact for 6-12 months then supply as required/requested by local site operator. All spare parts and consumables used in the network must be either manufacturer’s original parts, or manufacturer approved, where they come in contact with the sample gas/particles. The contractor will be required to the contractor must provide ‘hot spare’ monitors in the event that they are not able to repair any monitor in the network in order to maintain data capture within 48 hours of site visit for call outs, service or maintenance. It is envisaged that any new instruments purchased via lot 3, will be absorbed in to the Council’s service and maintenance agreement provided via this lot.
