DESCRIPTION OF REQUIREMENTS The United Nations Economic Commission for Africa (UNECA) seeks to engage a qualified Building and safety maintenance and repair Services provider and Architectural/Engineering firm to provide Professional Services for its headquarters in Addis Ababa, Ethiopia .The United Nations Economic Commission for Africa (UNECA) is committed to ensuring the safety, functionality, and long-term sustainability of its campus infrastructure. To uphold this commitment, ongoing upgrades and improvements are implemented to enhance both existing and future developments. One of the current planned upgrades is the replacement of the mechanical hanging system for the external granite cladding of the Zambezi Building. The Zambezi Building is an eight-story office building (Basement + Ground + 6 Upper Floors + Roof Terrace). Construction began in 2010 and resumed in June 2014. The building is organized along an east-west axis, consisting of two main rectangular volumes connected by a central core. Cylindrical open staircases at either end enhance the building’s safety by providing dedicated escape routes. The external façade is finished with plaster and paint, glazing, and granite cladding. The building façade incorporates granite cladding, covering an area of approximately 3,100 square meters. Each granite tile measures 600 x 300 x 20 mm. Two fixing methods were originally used for installation:  Direct Fix Mortar Method: Granite tiles are adhered to the façade using cement mortar or adhesive. This method is primarily applied around doors, windows, edges, and small tile pieces.  Mechanical Clip/Pin Method: The majority of the granite tiles are secured using a mechanical anchoring system affixed to the concrete wall. Over time, multiple defects have been observed in the cladding system. Some tiles have completely detached and fallen, while others remain loose or partially delaminated Companies expressing interest should note that this Request for Expression of Interest (REOI) serves as pre-qualification of the companies that will be invited to participate in the tender process .Intrested firms will be invited to the tender by "Request for Proposal -RFP" at later stage and the detail requirement will be further specfied in the RFP document.
