Consultancy Services for Preparation of Detailed Engineering Design, Cost Estimate and Tender Documentation for Construction of a Model Public Toilet Facility in Lahan Municipality

1. Background

Dalit Jan Kalyan Yuba Club (DJKYC) is a local, non-profit and non-political organisation based in Bastipur (Pradip Giri Ashram), Ward No. 14, Siraha, Nepal. Since its establishment in 2000, DJKYC has been working to eliminate discrimination and improve the well-being of women, children, and marginalised communities, while also contributing to Water, Sanitation, and Hygiene (WASH) improvements.

WaterAid Nepal (WAN) is implementing The Beacon Project: Municipality-Wide Equitable WASH Services in Lahan, a joint initiative of Anglian Water, its Alliance Partners, WaterAid, and Nepal Water Supply Corporation (NWSC). The project aims to support Nepal in achieving Sustainable Development Goals related to water and sanitation through the implementation of WASH sector plans.

As part of this initiative, a model public toilet facility is proposed along the East-West Highway within Lahan Municipality. Architectural designs and 3D visualisations have already been prepared. To proceed with procurement and construction of the facility, a complete engineering, cost estimation and procurement-ready documentation package is required.

DJKYC, on behalf of WaterAid Nepal and in coordination with Lahan Municipality, intends to engage a qualified consulting firm to prepare detailed engineering designs, technical specifications, cost estimates, bills of quantities, and tender documentation required for construction and contract procurement.

• Government of Nepal standards and specifications

• Climate-resilient and environmentally sustainable design practices
• WaterAid's inclusive WASH standards and guidelines

• Review the approved architectural design and 3D visualisation package.
