Lot 1: Construction of total capacity of 14,000m³ Reservoirs (7,500m³ & 6,500m³) for Akure Northern Reservoirs and distribution for Sector 1, in Akure (18 Months)

Lot 2: Distribution network for Akure “sector 2-7” in Akure city (18 Months)

The Scope of the services are into two stages I and II, which comprises of detailed engineering design review of Akure distribution networks (Stage I) and Supervision of Construction works (Stage II).  The task comprises gathering and reviewing the Akure distribution aspect of the design document produced during the earlier stage of the design in stage 1 of the contract with timeframes of 6 months and particularly involves the following tasks:

Stage I: Detailed Engineering Review (Including Bidding Documentation): The detail Report will have a number of elements including:

1.   Review of the existing DED for water infrastructure in Akure city and its environs

2.   Building of hydraulic model to verify the AFD proposal for transmission mains and distribution networks in terms of sizes and costs.

3.   Review (if necessary) of preliminary drawings, specifications, etc. for the contracts with timeframes from 6 months.

•     Inception Report: – Consultant shall submit its report outlining his mobilization, initial findings and works programme for Stage 1, Contract Documentation. He is expected to understand the project goals, scope, and requirements specified in the initial project documentation and also to review relevant local, state, and national standards and regulations governing water distribution networks.

•     Design Engineering Review: Consultant shall review the DED to include but not limited to the following activities:

–          Examine Design Drawings: – Scrutinize detailed engineering drawings for the water distribution network, ensuring alignment with project requirements and regulatory standards.

–          Check Hydraulic Design: – Evaluate the hydraulic design of the network, verifying that it meets the required flow rates, pressure levels, and distribution patterns.

–          Materials and Specification Review: – Examine material specifications, ensuring compliance with industry standards and suitability for the urban environment.

–          Evaluate Pipeline Layout: – Review the layout of pipelines, considering factors such as optimal routing, network redundancy, and accessibility for maintenance.

–          Check Valve and Hydrant Placement: – Verify the placement of valves and hydrants, ensuring they are strategically located for effective network control and maintenance.

–          Verify Resilience and Redundancy: – Assess the resilience and redundancy features of the design to ensure system reliability and continuity of water supply.

–          Evaluate Bill of Quantities (BoQ): – Examine the Bill of Quantities to ensure accurate quantity estimates for materials, labour, and other project elements.

–          Check Technical Specification: – Review technical specifications to confirm that they align with the detailed engineering design and industry standards.

–          Assess Contract Terms and Conditions: – Evaluate contract terms and conditions to ensure clarity, fairness, and alignment with project goals.

–          Verify Compliance with Procurement Regulations: – Ensure that the bidding documents comply with relevant procurement regulations and guidelines.

–          Review Bidding Documents: – Examine bidding documents for accuracy, completeness, and alignment with the detailed engineering design. Tenders shall be prepared for all contracts using the AfDB template.

–          Document Findings: – Record detailed findings from the review process, highlighting any discrepancies, issues, or areas for improvement.

–          Prepare Review Report: – Compile a comprehensive review report summarizing the consultant’s evaluation of the detailed engineering design and bidding documents.

–          The detailed design will incorporate all this and other investigated information for the Secondary transmission mains, reservoir sites and proposed networks.

•     Environmental and Social Impact Assessment & Security Safeguard: It is expected of the consultant to review the Environmental and Social Impact Assessment of the project site that has been carried out for the works contracts and based on same on the Environmental and Social Management Plan (ESMP) with security safeguard prepared for the construction stage and ensure compliance to international best practice.

•     Resettlement Action Plan: A Resettlement Action Plan has been prepared for the works, the consultant is expected to review the document and ensure it is implemented prior to works contract award.

•     Tender Documentation Support: Having reviewed all the tender document, the consultant shall support the ODWC during the tendering and tender selection process as may be needed.

The Consultant shall:

–          Review the existing water distribution Design to all the coverage areas in the context of the AfDB proposal for upgrading the primary and secondary networks. Assess through site surveys, GIS review and modelling which elements (reservoirs, site, pipelines etc) will be retained and repaired or replaced by new distribution mains.

–          Review engineering design showing the layout of the pipes their diameters, household connection points, fire hydrant locations, district meter and a valve sectorization, and pressure zone sectorization. For existing pipes, a schedule of repairs will likewise be prepared.
