Assignment Title: Development, Deployment, Hosting, and Maintenance of the Climate Risk Analytics Management (CRAM) Platform

Reference No. SL-NACSA-547305-CS-QCBS

Date Issued: 1st June 2026

The Government of Sierra Leone has received financing from the World Bank toward the Social Safety Net and Youth Employment Project (PSSNYE). The National Commission for Social Action (NaCSA), the project implementing agency, now intends to apply part of the proceeds for consulting services for Development, Deployment, Hosting, and Maintenance of the Climate Risk Analytics Management (CRAM) Platform under the Digital Public Works Subcomponent of the PSSNYE project.

Background

The Freetown City Council (FCC) is implementing the Digital Public Works (DPW) Subcomponent 2C under the Productive Social Safety Net and Youth Employment Project (PSSNYE). The subcomponent aims to strengthen urban climate resilience and disaster preparedness through the use of digital technologies and data-driven decision-making.

Freetown faces increasing environmental risks including urban heat stress, seasonal flooding, and ecosystem degradation. Addressing these challenges requires integrated climate data systems capable of consolidating environmental datasets, analyzing climate risks, and supporting evidence-based planning and response.

To support this objective, FCC intends to establish a Climate Risk Analytics Management (CRAM) Platform, a web-based, GIS-enabled climate intelligence system that will integrate and analyze datasets related to heat exposure, flooding, tree planting interventions, and socio-economic vulnerability.

The CRAM Platform will function as a centralized monitoring and analytics dashboard capable of aggregating data from multiple government agencies and partner institutions, including Freetown City Council (FCC), National Commission for Social Action (NaCSA), National Disaster Management Agency (NDMA), Sierra Leone Meteorological Agency (SL-Met), Statistics Sierra Leone and Office of National Security (ONS). The system will support FCC’s broader Transform Freetown: Transforming Lives Agenda, which emphasizes environmental sustainability, climate resilience, and data-driven urban governance.

Objective of the Assignment

The objective of this assignment is to design and implement a secure, scalable, and data-driven Climate Risk Analytics Management (CRAM) Platform that supports monitoring, analysis, and communication of climate risks across Freetown. The platform will:

• Integrate climate and environmental datasets from multiple institutions.
• Provide interactive GIS-based visualization of heat, flooding, and tree planting interventions.
• Enable descriptive and predictive analytics to assess climate risks and trends.
• Support institutional coordination in disaster risk management.
• Provide accessible climate information for policymakers, technical users, and the public.
• Establish a scalable digital platform capable of incorporating additional environmental datasets such as air quality, waste management, and water infrastructure. Scope of Work

The consulting firm will undertake the design, development, deployment, and operational support of the CRAM Platform. The detailed Terms of Reference (TOR) for the assignment can be obtained at the address given below.
