The Authority will be looking at a contract for PM2.5 analysers that has multiple contractors on it to call off against so the best analyser could be placed for different site types based on what the Authority consider to be the best instrument for the site type. A ‘call-off’ means that if you are successful on the tender to make the call off list - there is no guarantee of how many instruments the Authority will purchase from you.The Authority envisage having up to 7 Contractors on the call off contract. The priority is to have analysers that meet our technical needs for different site types and to ensure that the targets are measured consistently across the network using the best type of analyser for each site type, against the reference method, and to provide the instrument with the lowest uncertainty for the measurement of annual mean targets. Practical considerations on running costs, space requirements and capital budgets will be taken into account in our selections. Hot spares are likely to be ordered to assist the CMCU(s) to help achieve high data capture in the event of any instrument faults.1.1.
