The works under the Risk Mitigation project include development of the design solutions for the risk mitigation blast and fire resistant barrier to enclose ID Transformer rooms, Shunt Reactor rooms, and Earthing transformer room in 132/11kV substations in Dubai which are facing the roads, pedestrian areas or public spaces. Energoprojekt ENTEL was engaged to provide design and risk mitigation comprehensive analyses and reports, developing solutions from fully closed transformer rooms with artificial cooling and ventilation to the finally chosen solution with natural ventilation and partially transparent barriers. Despite being the time and cost most effective solution, the system posed an extraordinary engineering challenge: the transformer rooms shall simultaneously be opened for the natural air ventilation and cooling, and closed in case of accidents countering explosion and fire. Another aspect of the project took also the extraordinary effort: all substations are in highly populated areas of Dubai, usually with heavy pedestrian and vehicular traffic, and the site execution was the project for itself related to obtaining all required permits, harmonizing schedule with required power outages, prompt execution of technically challenging activities.
The Scope of Consultancy Services covers design solution (variants) development, tendering, participation in detailed design development, design verification, supervision, witnessing FAT/type tests and the project management services from project initiation to its end. The Consultancy Service is divided into two parts: the tendering and design stage, and the site execution stage.
Part 1 Covers Consultancy Services related to general design solutions and risk analysis report, project scope formation, project tendering process, FAT/type tests and project management services.
Part 2 includes all activities related to project construction execution including site supervision, inspection, material acceptances, and work verification.
