HYDROELECTRIC PROJECT: HUITES, MEX.

The executive design of the pipeline pressure, hydraulic vent channel design and alternatives to the comprehensive settlement of the powerhouse (2x211 MW) were performed. In accordance with MAC Engineering, it was executed part of the design works for the Brazilian generation Mexican consortium. The scope of services included the hydraulic and structural designs.

HYDROELECTRIC PROJECT: 289 CHICOASÉN II, MEX.

Hardfill dam 38.5 m high diversion structure in channel 25 m wide and 930 m long. Generation work with three bulb turbines 80 MW each. Water intake and conduction of 14.50 x 15.50 m. A work of exceedances with five radial gates of 14.50 x 23.00 m, 3 for the pouring of service and 2 for the auxiliary.

HYDROELECTRIC PROJECT: PUNTA NEGRA, ARG.

Basic and executive designs were recruited through Hidroconsultoría with a consortium (UTE) and given in a first phase. The project is a dam 95 m high and a powerhouse of 62 MW. The scope of services included hydraulic, structural, geological and geotechnical studies and final design work for the diversion dam and spillway and construction specifications. An earlier agreement covered the optimization studies and basic design of all project structures, making technically and economically feasible project.

In 2010 was hired to Technoproject / COIGSA update and complement of the final design of all works (except diversion ones). Technoproject performed detailed design of the dam and the whole geological and geotechnical during construction.

Activities performed:

  1. Update and supplement of the Executive Design.
  2. Current Executive Design Review and Elaboration of the Executive Design Revised.
  3. General characterization of the arrangement of the works with the definition of location and Geometric Structures; main parameters of operation, details and Instrumentation Geotechnical type treatments.
