Tenders Are Invited For Design, Supply, Installation And Commissioning Of A Wastewater Treatment System

Tenders are invited for Design, Supply, Installation and Commissioning of a Wastewater Treatment System 2. Project Information and MEP Layouts Pharo Foundation will provide bidders with the available Mechanical, Electrical and Plumbing (MEP) layouts explaining the general design and arrangement of the schools sewage system. Ground-floor sewage piping and drainage arrangements. First-floor sewage piping and drainage arrangements. Second-floor sewage piping and drainage arrangements. The layouts illustrate the general sewage routes, drainage connections, inspection points, floor drains and related components across the school development. The drawings are provided to assist bidders in understanding the general sewage-system design. However, the drawings identify themselves as guidance plans and indicate that they may be subject to technical, administrative, legal, construction or design changes. Bidders shall therefore: Conduct a physical site inspection. Verify all relevant dimensions, elevations, gradients and connection points. Confirm the location and suitability of the proposed treatment system. Identify any design discrepancy, conflict or omission. Prepare final technical calculations and shop drawings. Obtain written approval of the final technical submission before commencing the relevant works. The successful contractor shall remain responsible for delivering a complete, functional and properly coordinated system notwithstanding any omission that should reasonably have been identified through site verification and professional technical review. 3. General Scope of Works The successful contractor shall be responsible for the complete design and delivery of a functional wastewater treatment system, including, but not limited to, the following: 3.1 Investigation and design 1. Review all available architectural, civil, mechanical, electrical, plumbing and sewage documentation. 2. Conduct a detailed site investigation and verify existing construction conditions; sewage collection and discharge points; pipe sizes, routes, gradients and invert levels; ground conditions; available installation space; electrical supply requirements; access for operation, maintenance and sludge removal; treatedeffluent discharge or reuse arrangements; and coordination requirements with other construction activities 3. Assess the expected wastewater volume based on an estimated population of approximately 1,200 persons. 4. Prepare hydraulic calculations, organic-loading calculations, average and peak-flow calculations, processdesign calculations, equipment schedules, general arrangement drawings, process-flow diagrams, shop drawings, civil and structural details, mechanical and electrical diagrams, control-system diagrams, and treated-effluent and sludge-management proposals. 3.2 Supply and installation The contractor shall supply and install all components necessary for a complete wastewater treatment system, including, where applicable: Screening and preliminary treatment units. Primary treatment units. Biological treatment units. Tertiary treatment and disinfection units. Treatment tanks and chambers. Pumps and pumping chambers. Pipework, valves and fittings. Inspection chambers and manholes. Ventilation and odour-control systems. Electrical control panels. Level controls, alarms and monitoring devices. Sludge collection and handling components. Access covers, ladders and safety components. Treated-effluent storage, discharge or reuse components. Required foundations and supporting structures. All accessories necessary for safe and proper operation. 3.3 Civil, electrical and associated works The scope shall include all necessary associated works, including: Excavation and trenching. Foundations and reinforced concrete works. Tank installation and chambers. Backfilling and reinstatement. Protective structures. Electrical cabling, control wiring and earthing. Connection to the school sewage network. Making good all affected areas. 3.4 Testing, commissioning and handover The contractor shall: Undertake dry and wet testing. Conduct leak and pressure testing where applicable. Test pumps, controls, alarms and electrical systems. Demonstrate the system under operating conditions. Carry out treated-effluent sampling and testing. Rectify and retest any failed component. Commission the complete system. Train designated personnel. Submit all required handover documentation. The successful contractor shall provide all labour, supervision, equipment, tools, materials, transportation, consumables and specialist services required to complete the assignment, except where expressly stated otherwise in the final contract. 4. Design Capacity and Performance Requirements The proposed system shall be designed using an estimated population of approximately 1,200 persons. The bidder shall clearly state: The proposed daily wastewater design flow. The assumed wastewater generation per person per day. The average and peak hydraulic loading. The assumed influent characteristics and proposed organic loading. The treatment capacity and proposed treatment process. The anticipated treated-effluent quality. The estimated sludge-generation rate and proposed sludge-treatment and disposal method. The anticipated electricity consumption. The proposed measures for controlling odour and noise. The systems ability to accommodate variations between school operating and non-operating periods. Any allowance for future population growth. The standards or performance requirements against which the system is designed. The completed system shall comply with applicable environmental, public-health, wastewater-discharge, construction and occupational-safety requirements. Where numerical local discharge standards are not specified in the tender documents, the bidder shall identify the recognized wastewater-treatment standard proposed for the project. The proposed standard shall be subject to review and written approval by Pharo Foundation and its appointed project consultants. 5. Mandatory Eligibility and Due-Diligence Documentation The following documentation shall be submitted by each bidder and shall be evaluated on a mandatory pass-orfail basis. 5.1 Legal and regulatory documentation 1. A valid business licence. 2. Valid company registration documentation. 3. A valid tax-clearance certificate or equivalent evidence confirming compliance with applicable tax obligations. 4. Evidence of authorization to conduct business and execute the proposed works in Somaliland. 5. Copies of relevant technical licences, engineering registrations or professional certifications. 5.2 Company ownership and directors 1. A current list of all company directors. 2. A current list of shareholders or beneficial owners, where applicable. 3. Copies of valid identification documents for company directors or authorized signatories. 4. The companys memorandum and articles of association, incorporation certificate or equivalent formation documents. 5. A signed board resolution or power of attorney authorizing the person signing and submitting the tender. 6. Disclosure of any actual, potential or perceived conflict of interest involving Pharo Foundation employees, consultants, evaluation committee members or affiliated parties.
