Supply of Air Sampler for SES of the Republic of Uzbekistan

New amendment added #1: The RFQ is hereby amended to extend the bid submission deadline to Thursday, 1 October 2026, at the closing time specified in the UNOPS eSourcing system, to allow bidders sufficient time to consider the clarifications provided and finalise their bids. All other terms and conditions remain unchanged.

New clarification added: Q6: Please clarify the following requirements for the portable ambient air quality monitoring device: (i) Device configuration, dimensions and sensor arrangement: The specification refers to “a set of removable sensors”. Accommodating 16 separate sensors in a compact handheld device may present practical difficulties, while frequent sensor replacement may be time-consuming and could cause wear to the device’s components. A larger, briefcase-sized portable unit may accommodate integrated sensors and support simultaneous measurement of the required pollutants. Please confirm whether the requirement is for 16 separate sensors or the ability to measure at least 16 pollutant types. Please also clarify whether a compact handheld device or a larger portable unit would be acceptable, and whether any specific dimensions or weight limits apply. (ii) Spare battery - line 15: Some devices incorporate a built-in battery that is not intended for routine replacement by the user, but support an external power bank. Where battery removal requires specialist intervention or could damage the device, could an external power bank be accepted instead of a spare battery, or could the spare battery requirement be waived? (iii) Wall bracket -  Clause 17: A wall bracket may not be applicable to certain portable device configurations, particularly briefcase-sized units. Could this requirement be removed or qualified as “if applicable”, depending on the equipment offered?     A6: (i) The requirements in Section III, Returnable Bidding Forms, Form C concern each device’s ability to measure at least 16 pollutant types, rather than requiring 16 separate sensors. The technical specifications do not prescribe specific overall dimensions. Line 7 specifies “Portable (handheld)”, reflecting the intended use of the equipment. (ii)–(iii) Where a spare battery or wall bracket is not required or applicable to the proposed make and model, bidders may indicate this in the relevant comments box in Form C and explain the reasons. Where an alternative solution is proposed, such as an external power bank, bidders should describe how it supports the intended operation and functionality of the equipment. Please note, this solicitation is an RFQ, with the evaluation methodology of “lowest priced most technically acceptable”. Bidders are therefore free to propose the equipment configuration and technical solution they consider best suited to meeting the stated requirements and intended use. Any alternatives or deviations should be clearly identified and explained in the relevant comments box in Form C. Their technical acceptability will be assessed during evaluation, subject to review and approval by the end user.

New clarification added: Q5: Can the delivery period specified in the tender be extended from 60 calendar days to 130–160 calendar days from contract signature? Alternatively, would bids proposing delivery within this longer period be considered acceptable?    A5: Given the approaching project completion date, the required delivery period remains 60 calendar days from contract signature, DPU Tashkent, Uzbekistan. However, this solicitation is an RFQ, with the evaluation methodology of “lowest priced most technically acceptable”. The RFQ provides flexibility by stating that “Longer delivery terms may be considered only in the absence of substantially compliant offers.” Bidders may therefore propose their earliest achievable delivery period, including where this exceeds 60 calendar days, for consideration under this provision.

New clarification added: Q4: Please clarify the following: (i) must each of the 65 devices include 16 separate sensor types, or is the requirement to measure at least 16 pollutant types? (ii) Given the potential cost implications of the required configuration, will the solicitation method remain an RFQ or be changed to an ITB?     A4: (i) Each of the 65 devices must be capable of measuring at least 16 pollutant types. This may not necessarily require 16 separate sensor types. Please also refer to the response to Q1 above. (ii) The solicitation method will remain an RFQ. The evaluation methodology remains unchanged: selection of the "lowest-priced, technically acceptable offer".

New clarification added: Q3: Can the bid submission deadline be extended to allow additional time to prepare complete and compliant bids?    A3: To allow bidders sufficient time to consider the clarifications provided and finalise their bids, the bid submission deadline is extended to Thursday, 1 October 2026. Any further extension will be considered only if sufficient competition has not been achieved by the revised deadline.

New clarification added: Q2: Regarding the technical requirements for the Sensor Heads (Line 5), we note the requirement to provide sensors for "at least 16 types of pollutants, including those listed in Line 3." The document states that the additional sensors to reach the total of 16 "may be selected by the bidder," provided they are relevant to ambient or indoor air quality monitoring.Since different gas categories have significantly different hardware configurations and costs, could you please clarify: (i) does the end-user have a specific or preferred list for the remaining additional pollutants (along with their required measurement ranges and Limits of Detection) that they would like us to include? (ii) if there is no specific preference and the choice is entirely at our discretion, please confirm so we can optimize the configuration and pricing based on standard professional applications.   A2:  (i) The end-user does not have a specific or preferred list for the remaining additional pollutants. (ii) you may optimise the configuration in order to reach a total of 16 types of required pollutants, provided that they are suitable for professional ambient or indoor air quality monitoring by occupational health, industrial hygiene, environmental health, and public health professionals.

New clarification added: Q1: With reference to the technical requirements in Form C – Technical, we kindly request clarification regarding the requirements for interchangeable/replaceable sensor heads. The current specification requires a portable monitor base unit compatible with interchangeable sensor heads, replaceable sensor heads supporting at least 16 pollutant types, and a set of removable sensors. We note that professional portable air quality monitoring systems available on the international market may utilize different technical architectures. In particular, some systems use integrated or modular replaceable sensors/sensor modules rather than externally interchangeable sensor heads, while providing simultaneous measurement of the required pollutants and meeting the specified measurement ranges, limits of detection, data logging and portability requirements. In order to allow functionally equivalent technologies from different manufacturers, kindly clarify whether UNOPS would accept: "A portable air quality monitoring system using integrated and/or modular replaceable sensors or sensor modules instead of externally interchangeable sensor heads, provided that the offered system fully meets all required pollutant measurement ranges, LODs, PM2.5/PM10 performance, data logging, portable operation and other functional requirements specified in Form C. We would also appreciate confirmation whether a system capable of supporting at least 16 pollutant types through configurable internal or modular sensors would satisfy the requirement concerning the minimum number of pollutant types, even where the sensors are not designed as externally plug-in sensor heads. If acceptable, we kindly request confirmation that the corresponding references to “interchangeable sensor heads”, “different sensor heads”, “replaceable sensor heads” and “set of removable sensors” in Form C may be interpreted accordingly as allowing technically equivalent sensor architectures.     A1: A technically equivalent sensor architecture may be considered acceptable where the sensors or sensor modules are readily replaceable and their replacement or exchange does not compromise portable, handheld operation. The system must meet the functional requirements specified in Form C, including support for at least 16 pollutant types. Any proposed deviation remains subject to technical review and approval by the end user.
