The tender notice has been cancelled as of March 13th 2015 and remains for information purposes only. Please, do not respond.

Addis Ababa Water and Sewage Authority (AAWSA) is mandated, among other things, to plan, develop and maintain the city water and sewerage infrastructure. AAWSA is the sole provider of potable water for the city, the system of which has developed over the last 70 years with the exploitation of surface water and groundwater resources both within and outside the municipal boundaries. In recent years, the increased pace of economic developments of the capital city has placed continuing pressure on the water supply system to maintain pace with the resulting increased demands. With the aim of meeting the future water demand of the city, the AAWSA has secured a budget from Ministry of Water Irrigation and Energy under One WaSH National Program part of which is paid under contract Phase- I: Consultancy Service for Detail Design and Tender Document Preparation; and Phase-II: Consultancy Services for Construction Supervision and Contract Administration of Surface Water Resources of the Addis Ababa "Water III Project". The contract will be executed by the Government of Ethiopia through Addis Ababa Water and Sewage Authority's Water and Sanitation Development & Rehabilitation Project Office (AAWSA-PO).

The Addis Ababa Water Supply Project Phase III (commonly called Water III Project) was initiated by AAWSA 30 years ago with the purpose of planning, designing and constructing water supply systems that will effectively meet the growing water demands of the city. With a broad aim of bringing this project into implementation phase, the AAWSA-PO is therefore inviting potential interested international/national firms to undertake the consultancy services in two separate phases mentioned above. The objectives and scopes of the services are as outlined below:

Phase-I: Detail design and Tender Document Preparation of Surface Water Resources of the Addis Ababa Water III Project (Sibilu Dam and Ancillary Structures, Pumping Stations, Wesserbi Treatment Plant, Transmission Mains and Distribution Systems)

Objective of the study
*To prepare and operate quality assurance plans throughout the assignment;
*To carry out a comprehensive review of the Detailed Design of Sibilu Dam, Pumping stations, and transmission systems (2005) in order to address any short coming or deficiencies in order to assume full professional liability for the detailed design of the dam and its ancillary structures;
*To review recent findings in relation to hydrology and other issues, including reducing the impact of siltation;
*To review current situation at the dam site and incorporate any design changes necessary since the previous design was completed;
*To prepare up to date Aerial and Topographic Maps for the Sibilu Dam site and overall project area;
*To carry out geological and geotechnical studies and other surveys as required;
*To undertake detail environmental, social impact,costs and mitigation measures (Liaising of consultant in separate assignment is possible);
*To Prepare Draft and Final Detailed Designs for the dam and ancillary structures, pump stations, treatment plant, transmission mains, Construction Plan and Tender Documents including engineering cost estimates of all contract packages including dam, and associated works;
*To Prepare Draft and Final Outline Designs for the WTP and ancillary structures, and Tender Documents (Design Build – FIDIC Yellow Book) including engineering cost estimates of all contract packages including WTP, and associated works
*To Prepare Dam Safety, Instrumentation, and emergency preparedness plans with operation and maintenance manuals.This should cover Dam operating aspects e.g. operating rules for normal and emergency (flood) conditions and procedures for filling and emptying the hydraulic systems, and any other operating data not in the Contractors' Operation and Maintenance manuals;
*To Prepare an Operation and Maintenance manual for the WTP. In particular, this should cover WTP operating aspects e.g. operating rules for normal and emergency conditions and procedures for filling and emptying the hydraulic systems, and any other operating data not in the Contractors' Operation and Maintenance manuals.
