New amendment added #1: UNOPS Advises on the following points as below that HAVE BEEN AMENDED:Amended the document titled "RFP-2025-57975 - Section II_Schedule of Requirements_Amendment 01.1. Delivery requirements are amended to read as follows: Bidders shall deliver the goods and services in 60 days from the date of Contract/PO signature. The amendment is marked in red color.2. Deadline for clarifications will be extended until 09 July 2025.3. Deadline for submission of bids will be extended until 16 July 2025.4. Pre-Bid meeting: Powerpoint presentation of the UNOPS Procurement Process held on the 23 June 2025 and Minutes of Meeting have been included in the eSourcing "Documents" Tab.UNOPS advises to keep up to date with the published Amendment of the deadline for clarifications and submission of proposals as well as the delivery timeline.

New clarification added: Clarification request no. 03Regarding the information we received from you following our second request we are looking for the different parameters in the wastewater to be treated - for example:Wastewater quality for design (min, max, average) :pH  Temperature   BOD₅ (Biochemical Oxygen Demand)   COD (Chemical Oxygen Demand)   TSS (Total Suspended Solids)   Heavy Metals (Cd, Pb, Cr, Hg, Cu, Ni, Zn)   Cyanide   Phenols   Chlorinated organics  Toxic substances (e.g., solvents)   Radioactive substances   Microbiological (pathogens)  UNOPS clarification response no. 03Please note that the building in question is currently under construction, and as such, no wastewater sampling or laboratory testing has been conducted to determine specific quantitative values for the influent water quality. Consequently, the Schedule of Requirements does not include min/max/average figures for parameters such as BOD₅, COD, TSS, heavy metals, cyanide, phenols, solvents, or microbiological/pathogen levels.However, the Schedule of Requirements provides a qualitative overview of the anticipated composition of the laboratory wastewater, based on the activities planned in the Departments of Chemistry and Biology. These include the use of:Acids, bases, and solventsOxidizing and reducing agentsHeavy metalsDisinfectants, fixatives, and stainsMicrobial culture materials and biological residuesThe treatment system should therefore be designed with the flexibility to handle variable and mixed wastewater from typical laboratory operations, encompassing both chemical and biological contaminants.Should further characterization or sampling be required, this can be explored during the implementation stage, once the facility is operational.Please do not hesitate to reach out should you require any additional clarification.

New clarification added: Clarification request no. 02Please provide the quality of the wastewater at the inlet to the system to enable us design the suitable system.UNOPS clarification response no. 02Thank you for your request for clarification.Please be advised that the required information regarding the inlet wastewater quality is outlined in the Section II: Schedule of Requirements and further detailed in the Technical Specifications & Layout and Equipment Design section provided. For ease of reference, a summary is provided below.As per the login data provided:Peak Flow Rate: 0.893 l/sDaily Flow Volume: 25–30 m³/dayFlow Velocity: 0.8 m/sPipe Diameter at Discharge: Ø110 mm, h/d = 0.5Please note that these are indicative ranges and actual values may vary based on lab activity schedules and chemical usage. The final design should incorporate a degree of flexibility to handle fluctuations.If you need any further clarification, please feel free to submit your queries through the Clarification tab in eSourcing.

New clarification added: Clarification request no. 01The timetable for submitting an offer for this tender is very tight, therefore we kindly ask for an extension of the submission date to 23 July 2025.UNOPS clarification response no. 01Thank you for your message and for your interest in RFP/2025/57975.We acknowledge your request for an extension of the submission deadline.
