This project consisted of the preparation of contract plans, specifications, and project-related permits to reconstruct the St. Charles Rd. to North Ave. segment of I-294. The overall project scope to reconstruct and improve existing mainline pavement and bridges included realigning the Eisenhower Expressway Exit Ramp S (westbound I-290 to eastbound US-20 Lake Street), retaining wall and noise wall design, relocation of a gore area, traffic control, erosion and sediment control, detention pond grading, storm sewers and roadside ditches, and replacing an overhead sign structure.
d’Escoto provided Phase II civil engineering services and was responsible for the following:
• Roadway design
• Designing drainage structure—including modifications to the existing system
• Creating 3D models with MicroStation and Geopak for:
o Eisenhower Expressway Exit Ramp S and adjacent detention ponds.
o Roadway—including retaining walls and temporary soil-retention systems.
• Extracting and calculating staged earthwork quantities from 3D model
• Preparing over 300 cross-section sheets
• Creating smoothness-assurance reports utilizing ProVAL
• Compiling project-specific specifications
• Developing process for coordinating summary of quantities sheets and cost-estimates—created construction cost-estimate.
• Assembling / coordinating specifications, SOQ, and cost-estimates for the multi-firm team
