New clarification added: QUESTION:Given that our company specializes in providing professional pest control services, while the overall project scope is primarily focused on building construction, we would like to seek clarification on how specialized service providers such as ourselves can participate in this tender process.Specifically, would it be more appropriate for our company to participate as a subcontractor under an appointed main construction contractor, or does the United Nations Office for Project Services (UNOPS) provide a mechanism through which specalized service providers can be identified, considered, or connected with main contractors bidding for the project?Addionally, we would appreciate guidance on whether there are opportunities for specialized service providers to submit independent bids for specific components of the project, particularly pest control, termite treatment and other related services that may be required during construction or upon project completion.We would appreciate your clarification on the appropriate procurement procedures and opportunities available to specialized service providers to ensure our participation aligns with the tender requirements.ANSWER:The scope of works included in this tender does not include Specialized Pest Control Services. As stipulated in the ITB document the scope is primarily construction of toilet blocks and rain water harvesting tanks.With regards to the services that you offer, we encourage you and similar companies to register and apply for applicable opportunities when they are advertised on the United Nations Global Market (UNGM). 

New amendment added #1: This amendment is to extend the notification deadline for the bidder to confirm joining the Site Visit, from 7 days to 2 days prior to the visits. 

New clarification added: QUESTION (For Lot 1 & 2):Given the groundwater salinity concerns identified in Section V, clause 2.1.1, and the risks of prolonged dry periods, could UNOPS confirm whether site-specific water-source feasibility assessments, groundwater testing and rainwater storage-sizing calculations were undertaken?In particular, how has the proposed system been assessed to ensure reliable year-round water availability for schools and health centres, and are alternative or backup water sources available?We would appreciate any supporting technical assessments used to determine the proposed water supply designs.ANSWER:Groundwater Extraction and Testing:The scope of works under this tender does not include groundwater extraction, borehole drilling, or aquifer abstraction. Consequently, site-specific hydrogeological assessments and groundwater salinity testing are not required for the execution of this contract.Rainwater Sizing and System Design:The technical scope is designed to augment and retrofit the institutions’ existing rainwater harvesting capacity to enhance water security during dry periods. Sizing and technical specifications were developed based on available roof catchment areas, local rainfall patterns, and institutional stakeholder consultations. The design has undergone formal technical review and certification by the UNOPS Infrastructure and Project Management Group (IPMG).Alternative / Backup Water Sources:The development of alternative water supply sources (e.g., desalination, deep-well drilling, or off-site reticulation) is outside the scope of this tender. Bidders are required to price strictly against the Bill of Quantities (BoQ) and Technical Specifications provided in the solicitation documents.Best Regards,
