MWRDGC Stormwater Management Phase II Planning and Design Services

Hydraulic Analysis in  IDOT R2D2

Performing duties as Hydraulic Engineering Manager, ASE conducted hydraulic analysis in Joe Daviess, Henry, Rock Island and Winnebago Counties.  ASE developed the hydrology using Rational or TR 20 method, depending upon whichever was appropriate per site. The hydraulic models used were HY-8 or TR 20. ASE designed roadway ditches for capacity and any necessary ditch linings based on computed shear stresses. ASE designed the culvert erosion protection using BDE Figure 41-2.F and District Standard 19.4, and ASE designed outlet protection. The sites in the project include:

Sanitary Sewer and Water Main Design, Touhy Avenue, Des Plaines

ASE provided sanitary sewer and water main design on Touhy Avenue. ASE completed the following tasks to complete this project.

• Coordinated the new sanitary sewer and water main design with other project elements. Elements included existing topography, existing utilities, proposed storm sewers, proposed structures, proposed geometric plan and profile information, rail and stream crossings, future tollway ramp crossings, and other proposed utilities along this common corridor.
• Designed the new mains to meet Des Plaines and IDOT standards.
• Coordinated the staging for the utility construction with the roadway and other utility improvements so that existing water and sewer remain in service during the process.
• Coordinated fire protection services.
• Assisted the mechanical and structural engineers on the Lift Station Design.
• Determined hydrant and valve locations.
• Designed casing requirements and limits for the various crossings.
• Prepared a bill of material and sequencing schedule as required.
• Determined pavement patch locations, sizes, expected depths, etc. for standard IDOT planning (if any).
• Prepared IEPA water permit applications for both Sewer and Water.
• Prepared any Special Provisions needed.
• Prepared Quantities and Estimate for the proposed work.
• Addressed comments received from agencies including Des Plaines, Cook County Department of Transportation, IDOT, MWRD, the Tollway, and utility companies.
• Coordinated potential additional Des Plaines Sanitary Sewer and Water improvements along Mt. Prospect Road.
• Performed utility coordination for outside related relocations such as NICOR, ComEd, AT&T, and similar entities.

Civil Engineering Services for Forest Preserve District of Cook County

ASE performed professional civil engineering design services for the Forest Preserve District of Cook County at existing park facilities across Cook County as the civil engineering consultant to the project architect.  ASE was hired as the Civil Engineer in coordination of utilities, roadway geometrics, and utility design. Services included cost estimates and comparisons for different utility alternatives.  ASE provided designs for gravity sewer, forced main sewer, subsurface effluent disposals, public water systems and well water options. We provided civil engineering designs for different utility routing, types, and methods to ensure a cost effective and complete utility package and innovative alternatives for providing utility services to park facilities.  ASE worked closely with permitting agencies to guarantee approval and established relationships with permitting personnel for permitting processes, applications and scheduling.  ASE staff designed roadway geometrics, drainage and erosion control measures that complied with local, state and federal standards.  All design activities were coordinated with utility owners, code enforcement agencies and team members.
