The activities executed under this Bid-Build Project covered the penultimate phase of the overall program including efforts to clean and rehabilitate the lake with focus on a surface area measuring nearly seven million square meters. Work involved the construction of two types of basins, treatment of local plants and ground-level excavation of the foundations of the lake. Mass earthworks, construction of berms with the excavated material (protected with geotextiles and hydroseeding) and irrigation/electrical work was completed. Desiccation services are used to transfer water from the existing ponds to the new work areas. The project moved more than 1.5 million cubic meters of material and more than a million tons of gravel, including extensive mechanical and electrical work. Even with extensive design changes and inclement weather impacts, the Project finished on schedule, allowing for work to be completed ahead of severely impactful environmental restrictions.
