The construction of the Diego Martin Vehicular Overpass (DMVO) with associated connector roads and drainage system is a TT 190 million dollar project being undertaken by the Government of Trinidad and Tobago through the National Infrastructure Development Company Limited (NIDCO) with China Railway Construction (Caribbean) Company Limited (CRCCL)- Junior Sammy Constrators Limited (JSCL) as the design-build contractor. The project is aimed at the improvement of the traffic circulation between the Diego Martin Highway and the Western Main Road as well as improving the drainage system to alleviate major flooding issues in the immediate area.
Alvair supported Infrastructural Design Limited (IDL) to conduct the condition survey for existing drainage systems within the communities. Alvair provided support for the development of the Drainage Emergency Action Plan with recommendations aimed at immediate flooding relief along the Diego Martin Highway and the Western Main Road as well as the development of the overall drainage design for the DMVO project. Alvair also conducted pre-condition baseline surveys for a total of approximately 188 existing properties (including 8 multistorey apartment buildings, such as Victoria Keys and Powder Magazine Phase 2) within a 100 meter radius of the proposed DMVO and associated connector roads and drainage works.
