“Build For Tomorrow” – Key Takeaways from Midwestern Infrastructure Summit

Mark Stapleton, P.E.

Businesses, workers, citizens, and elected leaders came together this week to participate in National Infrastructure Week, May 13-20, 2019. The message this year is: America’s future will be shaped by the infrastructure choices we make today. #BuildForTomorrow

One of the many events that took place nationwide was the Midwestern Summit hosted by the Michigan Infrastructure and Transportation Association (MITA) and the Michigan Municipal League (MML) held at the Lansing Brewing Company in Lansing, Michigan.  State and local leaders discussed a regional strategy for economic success, the future of funding and financing infrastructure, and enhancing connectivity. I was fortunate to attend this summit and have a few key takeaways from the event.

Leading the Urban Infrastructure Renaissance

“People attract businesses. Places attract people. Good infrastructure makes good places.”

~ The Honorable Andy Schor, Mayor of Lansing, MI.

Takeaway #1: Quality infrastructure creates a quality lifestyle that attracts quality citizens. Investing in our towns and villages promotes economic success.


What’s next in Infrastructure Funding and Finance?

“Continuing to do things the way we have done them in the past is not working today regarding transportation. For instance, Michigan has 1,200+ bridges that are structurally deficient. The longer we wait to fix them, the more it will cost to repair them.”

~ Mike Nystrom, Executive Vice President / Secretary, Michigan Infrastructure and Transportation Association.

Takeaway #2: The first step is educating community members on how infrastructure improvements are funded and financed. The next step is conversations with private and public entities to create and implement viable solutions.


Beyond Asphalt and Concrete: Infrastructure for Place Making

“Successful business is built on human capital and human intellectual property and place attracts people.”

~ Jared Fleisher, Vice President Quicken Loans Family of Companies

Takeaway #3: Private companies are investing in good infrastructure because it is good for business and their employees.

Final Takeaway: Infrastructure is built from the ground up. As geotechnical engineers, we have the opportunity to work with both private and public sectors to build sound, quality infrastructure for this generation and the next.

New Soo Lock for Michigan’s economy, security

G2’s Mark Stapleton, P.E., is an associate and project manager at G2 Consulting Group – Ann Arbor.

The importance of the Soo Locks to the nation’s shipping and security has been in the news a lot lately.

In 1988, I was working for the U.S. Army Corp of Engineers and helped develop a comprehensive Soo Locks analysis called “Connecting Channels,” specifically drafting the chapter relating to the Locks’ critical role in America’s national security. Almost 30 years later, the Soo Locks remain vital, but have yet to be updated.

The Soo Locks opened in 1855 and have been used by everyone from Native Americans, French explorers and fur traders to today’s massive Great Lakes freighters.  The Locks now account for the transportation of 90 percent of the world’s iron ore, as well as, tons and tons of stone, coal, cement, grain and other cargoes. Over 60 million tons, and more than 3,000 freighters pass through the locks annually.

Virtually everybody agrees that the Soo Locks are vital to the nation’s security. The Department of Homeland Security estimates that closing the Poe lock alone, one of four locks (only two of which are operable) at the Soo, would likely cause a complete shutdown of Great Lakes steel production and ultimately cost 11 million jobs, most of them in Chicago, Detroit and Cleveland. Therein lies the national security concern.

Those in the know agree that the locks are in desperate need of updating, including the need for a second large lock capable of handling the 1,000 foot cargo ships now traversing the Great Lakes.

The Mid America Association of State Transportation Officials representing 10 Great Lakes states officially petitioned Congress last month to fund the construction of this new lock.  Even President Trump weighed in when he promised in a recent speech in Washington Township that the Locks will be fixed.

Congress authorized construction of a new lock in 1986 and authorized full federal funding in 2007 but still hasn’t authorized the estimated $600 million to fund construction of the lock. The pressure is building to get the job done and the U.S. Army Corps of Engineers, the people who will have to manage the process, are being pushed to speed it up.

Getting the job done won’t be a walk in the park.  Some experts suggest it could take as long as 10 years and cost as much as $1 billion. To give you some idea of the difficulty of the undertaking, the bedrock at the locks is Jacobsville sandstone, a reddish stone that is up to 1,000-feet thick.  Imagine drilling into that underwater mass just to be able to understand the construction needs.

My current company, G2 Consulting Group, specializes in the types of geotechnical engineering skills that will be required to get the job done.  We’ve been doing it for 22 years in over 35 states. Our experience includes harbors and rivers, bridges, arenas, skyscrapers, highways, and more. Obviously we’d like to participate on the Soo project, too, but regardless of who wins the work, the job clearly needs to be done – the country’s commerce, our jobs and our security depend on it.


Transformers: Dominick’s Grocery to Emagine Theatre


You know it as a movie, but G2 Consulting Group became “Transformers” when it helped convert a former Dominick’s Grocery Store into a 10-screen Emagine Theatre – the first in the state of Illinois. The fast-tracked project consisted of a 70,000 square foot slab-on-grade building that required the removal of portions of floor slab and grade cuts of up to 10 feet to construct the individual theaters. Building columns were relocated as needed and the roof beams were reinforced to carry additional loads.

Fast Facts

Project Owner
Emagine Theatre

Project Scope
G2 Consulting Group worked collaboratively with Tower Construction (GC) during all phases of the project to construct the first Emagine Theatre in Illinois.

Services Provided
Geotechnical Investigation
Environmental Engineering Services (Phase I, Asbestos Survey)
Quality Assurance / Materials Testing / Steel Inspection
Clean Construction or Demolition Debris (CCDD) Services

Challenges / Solutions
G2 Consulting Group found that existing fill soils were present below the floor slab and allowed for new foundations to wear on existing soils provided they were observed and properly documented during construction.

The project moved at a very fast pace and G2 was available to cover inspections on short notice – sometimes within two hours of being called. This allowed the project to move forward without delays.

How did we accomplish “Smart. Results. Fast”?

Soil borings within the interior of existing buildings can be challenging due to height and width restrictions of drilling equipment. G2 used its contacts with local drillers to determine the best equipment to allow for access and drilling within the building and work was completed in two days. G2 also coordinated environmental surveys at the same time as drilling to minimize delays to the project and minimize interruptions to the building.

G2 fast-tracked CCDD testing on short notice to allow for offsite disposal of soils and allow the contractor to stay on schedule with soil removal. There was no place to stockpile soils and any delays with soil removal would have hindered the project timeline.


“Quality of Life” improves with Downtown Fenton Streetscape project

Fenton, Michigan

G2 Consulting Group was part of the construction team that earned two industry awards for its work on the Downtown Fenton Streetscape project.

Country Club of Detroit Athletic Facility

G2 Consulting was retained by McCarthy and Smith, Inc., to design a support system so the construction team could excavate underneath the original “natatorium wing” of the 1930s historic clubhouse. The renovation plans called for relocation of the club’s popular bowling facility to the lower level location previously occupied by an indoor swimming pool, which had been out of use for decades.

Club management’s direction that the building’s architectural character and footprint not be altered in any way created an interesting engineering challenge since the team would need to excavate underneath the existing structure without disturbing it.  Adding to the challenge, the underlying soil conditions were poor with clay along one side of the structure and wet sand along the other.  After considering numerous approaches, the team decided on a series of underpinnings, essentially putting the building on stilts, and then pouring concrete foundation walls to encapsulate the stilts, providing stability for the renovations to occur in the short term and adequate bearing for the long term.

Unique Shaft System Facilitates Rehab of Interceptor

Jason Stoops, P.E Ann Arbor Office Manager

Nicholas A. Berkholz, EIT
Project Engineer

The Oakland-Macomb Interceptor Drain (OMID) is a 50-year-old concrete system bordering Oakland and Macomb Counties in southeast Michigan. Authorities targeted more than seven miles of this large diameter interceptor sewer – 40 feet below a busy county road (M 59) – as a priority for evaluation and repair to avoid catastrophic failure.  This project is part of a $160 million effort that has been under construction since 2009.  Given the unique opportunity the project afforded to have access to this critical trunk sewer, the owner’s objective was to perform as many repairs possible.

Lanzo Trenchless Technologies was selected to  provide multiple rehabilitation services, including  high volume sewage control management, cementitious grout in place liners, fully deteriorated model CIPP, large bore spot repairs, cementitious grouting of voids, access manhole restoration, localized crack/failure repairs using chemical grout and CCTV.  Challenges included working in and around flow that could not be disrupted during the construction process.  Work was difficult and dangerous, and required extreme care in safety consideration, monitoring and management.

One of the first tasks of the project was to tunnel a shaft down to the 96-inch diameter sewer crown, create access and build a platform for staging of both the chemical and cementitious grouting activities within the pipeline. Lanzo retained the services of G2 Consulting Group to design two 16-foot diameter corrugated steel liner shafts to gain access to the existing sanitary interceptor approximately 20 to 25 feet below ground surface.  To meet project requirements, G2 designed a shaft system that is uncommon for this part of Michigan.
