DESIGN, CONSTRUCTION SUPERVISION AND MANAGEMENT CONSULTANCY UNDER TRANCH 3 OF NERCCDIP-AIZAWL
1. Background Information
1 The Government of India has taken loan to implement an investment program to improve urban conditions in North Eastern Region capital cities, namely, Agartala, Aizawl, Gangtok, Kohima and Shillong. The expected impact of the Investment Program is improved environment and well-being of urban residents in the five capital cities. The expected outcomes of the Investment Program will be an increased access to better urban services for the 1.5 million people expected to be living in the Investment Program cities by the 2014.To this end, the Project will (i) improve urban infrastructure and services, (ii) strengthen urban institutions for better service delivery build project management and implementation capacity.
2 The Project will comprise two parts: Part A will cover urban infrastructure and services improvement including the rehabilitation, improvement and expansion of (i) water supply, (ii) sewerage and sanitation, and (iii) solid waste management. Part B will cover Investment Program management and implementation support and a comprehensive capacity building assistance to support the accomplishment of the urban institutional and financial reform agenda, and enhance planning, operation and maintenance (O&M), revenue mobilization, and financial management capabilities of service providers.
3 In Aizawl, the Project will specifically support water supply source augmentation, rehabilitation and expansion of the water distributions system – namely source augmentation, treatment plant, storage, transmission and secondary distribution systems – and comprehensive non-revenue water (NRW) program, which will include installation or replacement of bulk water meters as well as a leak detection program for rehabilitation and strengthening of the existing distribution network. In addition the program will also support the Government in (i) improving sanitation facilities, including sewerage and sewage treatment in most congested and also Septage Management and (ii) developing solid waste management facilities, including composting facilities, an engineered landfills site, improvements to primary and secondary collection as well beneficiary awareness.
2. Overall Scope of Work
4 The work under this design and supervision consultancy for the investment program in Aizawl will consist of (a) conducting necessary surveys, investigations and tests, (b) technical appraisal of subprojects and updating preliminary designs (if deemed necessary), (c) detailed engineering designs/review of design, (d) construction supervision and contract monitoring, (e) Monitoring safeguard Measure and Preparation and Monitoring Project Performance Monitoring System (PPMS).
5 The assignment will be structured in Tranches, which will largely correspond to each of the tranches under implementation. The assignment has been structured to ensure that whilst designs may be completed in advance, supervision matches each of the tranche releases under the investment program. The work under Tranche 1 has been completed. Procurement under Tranche 2 has been completed and execution is in progress.
