IH-45 South FM 1764 to FM 519


Drainage Improvements

  • AEL was contracted by AECOM to perform engineering services for a 2.2 mile stretch of IH45 South from FM 1774 to FM 519. Design included preparing drainage area maps, storm drainage plan and profile sheets, culvert layout sheets, bridge class culvert layout sheets, hydraulic data sheets for storm drains, standard details sheets, and nonstandard details sheets by utilizing Geopak Drainage. The corridor was to be designed for the 10-YR storm event. Geopak model took into account the peak flows for subcomponents of the drainage system, drainage system design/calculations for the main lanes, retaining walls, bridges, ramps, and frontage roads. All designs were made in accordance with the the latest edition of the State Hydraulic Manual, Districts criteria, and any specific guidance provided by the state. AEL coordinated with the state and designers of adjacent projects to check that all proposed drainage systems accommodate the proposed construction phasing plan. Managed the budget, production tasks with the team and coordinated with the client.
