We partnered with a chemical manufacturer to address heavily eroded ditch banks adjacent to an existing industrial access road at their facility.

We gathered topographic survey data at each area of concern, performed a geotechnical field investigation to gather soils data, and performed a slope stability analysis of the primary area to ascertain the potential risk. It was determined that, without improvements, the bank was indeed at risk of failure at the primary area.

We provided a summary of creek bank improvement options, which included slope re-grading, riprap, gabion baskets, a retaining wall, and others. Each option included a summary of the permitting required prior to implementing the improvements.

We prepared a design for 215 linear feet of new sheet pile retaining wall to repair the bank, prevent loss of pavement and gain more pavement for truck safety.

We obtained necessary permits, performed construction observation, and prepared record drawings.

Due to significant roadway flooding within the Northbrook East Subdivision, the Village of Northbrook in Illinois identified this project as a high priority in their Stormwater Management Plan.

We provided full-service professional survey, phase I, II, and III design, and resident engineering services for the project, including approximately 400 feet of relocated bike path.

Final improvements include 1,557 linear feet of new storm sewer to supplement the existing sewer network, a 4.7 acre-ft. stormwater detention pond with a dry bottom basin restored with native plantings for water quality enhancement, 150 new trees, relocation of an existing bike path, storm sewer improvements, watermain and water service improvements, and pavement, sidewalk, and vegetative surface restoration.

We surveyed existing conditions, performed stormwater modeling, prepared construction drawings, obtained all required regulatory permits, participated in all public outreach, acted as the Resident Engineer, and prepared Record Drawings.

Construction of the facility was completed in December 2016.

We designed the replacement of a failing potable water well with a new well 750 GPM deep water well, replacement of two existing aboveground water storage tanks of 350,000 gallons capacity with new two new tanks totaling 500,000 gallons capacity, and replacement of the associated aeration treatment system, piping, and service pumps at Jacksonville University in Jacksonville, Florida to provide a complete water supply and treatment system. This system was needed to replace the existing aging and failing systems. One of two existing wells was abandoned and the remaining well serves as a backup to the new well.

We prepared site/civil design plans, mechanical, electrical and controls plans, erosion and sediment control plans, and associated details and specifications.

We were awarded the project as design-build, and services included obtaining permits, and performing construction and construction management services.

We provided professional engineering services to the Chicago Department of Aviation (CDA) for the Bessie Coleman Water Main Project at Chicago O’Hare International Airport.

This project included all tasks necessary to design approximately 1.4 miles of new water main along Bessie Coleman Drive, Schlitz Road, through the Airport Transit System (ATS) and parking lot areas, and in the area east of the Signature Fixed Base Operation (FBO) building.

The new water main replaced an existing water main that was either at the end of its service life and/or is not in a desirable loop configuration.

The CDA did not implement the design when initially completed and put it out to bid several years later.

Additional airport improvements had been constructed in the intervening years and 5,000 feet of additional water main were added to the scope of the project.

Necessary design changes were fast tracked and run concurrently with the bidding and construction of sections of watermain that had not been affected by changes in order to prevent delay of the construction schedule.

We performed design of a levee and associated improvements to reduce the impacts of flooding from the Little Calumet River into an adjacent residential neighborhood.

Our scope included a detailed watershed study to confirm watershed limits and identify up to three conceptual solutions to manage overland flow on the land side of the levee.

The team performed a detailed river survey to obtain adequate bank cross sections and bathymetric survey to perform detailed hydraulic design of the river modifications and to adequately model the river for the dam modifications, rock riffle, and levee design.

Geotechnical field investigation was performed to determine foundation conditions for the levee and potential borrow sources for levee construction.

Preliminary design included the levee, detention basins, pump stations and storm sewer improvements to handle storm water flows upland of the proposed levee.

Phase 1 included removal of the top of an existing sheet pile wall dam across Deep River, installation of rock riffles with fish and canoe passages, a boat launch constructed of articulated concrete block mat, public parking areas, and a bike path with pedestrian bridge connecting the residential area to a recreation building on the other side of the river. Phase 1 was completed in 2021.
