METEOROLOGICAL MAST TOWER

Terms of Reference for IUCN Consultancy Title: CONSTRUCTION OF A 50 M METEOROLOGICAL LATTICE MAST /TOWER. Objective of the Consultancy Main Objective To construct a safe, durable, structurally sound, and fit-for-purpose tower to accommodate Eddy Covariance equipment for long-term monitoring of greenhouse gas fluxes and ecosystem–atmosphere interactions within the Rufiji Delta mangrove ecosystem, in accordance with the approved technical specifications, engineering standards, and site-specific environmental and safety requirements. Specific Objectives i. To undertake the site preparation, foundation works, fabrication, transportation, assembly, erection, and construction of a structurally sound and fit-for-purpose tower capable of safely accommodating the Eddy Covariance system and associated scientific equipment, in accordance with approved technical specifications, engineering drawings, and applicable standards. ii. To ensure that the tower incorporates appropriate structural stability, anchoring/guying systems, access and safety provisions, and durable corrosion-resistant materials, taking into consideration the site-specific conditions of the Rufiji Delta, including mangrove canopy height, soil conditions, wind loads, tidal influence, flooding, high humidity, and salinity. iii. To ensure that all construction works comply with applicable quality assurance, occupational health and safety, environmental safeguards, and Tanzanian engineering and construction standards, including final structural inspection, verification, site restoration, and handover of a completed tower ready for installation of the Eddy Covariance equipment by the designated equipment supplier. Background Project Reference: P04809 Donor reference: (DN00140) About IUCN IUCN is a membership Union uniquely composed of both government and civil society organisations. It provides public, private and non-governmental organisations with the knowledge and tools that enable human progress, economic development and nature conservation to take place together. Created in 1948, IUCN is now the world’s largest and most diverse environmental network, harnessing the knowledge, resources and reach of more than 1,400 Member organisations and around 15,000 experts. It is a leading provider of conservation data, assessments and analysis. Its broad membership enables IUCN to fill the role of incubator and trusted repository of best practices, tools and international standards. IUCN provides a neutral space in which diverse stakeholders including governments, NGOs, scientists, businesses, local communities, indigenous peoples organisations and others can work together to forge and implement solutions to environmental challenges and achieve sustainable development. Working with many partners and supporters, IUCN implements a large and diverse portfolio of conservation projects worldwide. Combining the latest science with the traditional knowledge of local communities, these projects work to reverse habitat loss, restore ecosystems and improve people’s well-being. www.iucn.org https://twitter.com/IUCN/ Terms of Reference for Consultancy v1 March2024 About the Project Pamoja Tuhifadhi Bahari Yetu Project is a four-year initiative (2024–2028) funded by the European Union and implemented under the Blue Economy for job creation and climate change adaptation. The Project aims to contribute to improved environmental protection and biodiversity conservation of Tanzania's coastal and marine ecosystems and to support the development of a climate-resilient Blue Economy. The Project is implemented in selected coastal and marine landscapes in Mtwara, Lindi, Coast and Dar es Salaam regions on Mainland Tanzania and Unguja Island in Zanzibar. The Project is led by the International Union for Conservation of Nature (IUCN) in partnership with WWF, Wildlife Conservation Society (WCS), The Nature Conservancy (TNC) and ForumCC. Tanzania's coastal and marine ecosystems provide significant ecological, social and economic benefits, including carbon sequestration and storage, fisheries production, coastal protection, biodiversity conservation and livelihood opportunities. However, these ecosystems are increasingly affected by climate change, habitat degradation, unsustainable resource use, pollution and limitations in the availability of long- term scientific information required to support evidence-based management and policy decisions. The Bahari Yetu Project's Theory of Change recognizes that stewardship of marine biodiversity and the Blue Economy can be strengthened through improved science-based natural-resource management and governance; increased economic benefits from conservation-based enterprises; adoption of technologies and approaches that strengthen climate resilience; improved knowledge management and institutional capacity; and strengthened evidence-based research, monitoring, policy development and implementation. Under Work Package 4 (WP4), the Project is strengthening institutional capacity for research, monitoring and governance. One of the strategic investments is the establishment of an Eddy Covariance (EC) monitoring station within the Rufiji Delta mangrove ecosystem to enable continuous measurement of exchanges of carbon dioxide, water vapour and energy between the mangrove ecosystem and the atmosphere. Description of the Assignment IUCN Tanzania Country Office, through the EU-funded Pamoja Tuhifadhi Bahari Yetu Project, intends to engage a qualified engineering/construction firm or company to undertake the detailed engineering, supply, fabrication, construction, erection, structural testing and handover of a permanent Eddy Covariance lattice tower/mast at the Rufiji Delta mangrove monitoring site in Nyamisati, Tanzania. The tower will provide the permanent structural infrastructure required to accommodate an Eddy Covariance monitoring system and associated meteorological and monitoring equipment.
