Huron Academy, a tuition-free public charter school for 3rd through 7th grade students, expanded its operations in 2015 by purchasing a 19-acre parcel along Utica Road in Clinton Township.
The new, $8.4 million, 32,000 square foot, single-story building features 22 classrooms, computer labs; a gymnasium; special spaces for music and art; a science lab; and a state-of-the-art media center. The site was once home to Bishop Gallagher’s athletic fields. Some of the existing athletic fields are preserved for use today.
G2 Services Provided: G2 Consulting Group worked with Partners in Architecture of Mt. Clemens and provided geotechnical engineering services. G2 also provided special inspections and materials testing services for general contractor Cunningham-Limp Company of Novi.
In addition to special inspections and materials testing, G2 evaluated earthwork operation and utility backfill, foundation construction, masonry evaluation, structural steel evaluation, and interior floor slab and site concrete evaluation.
Challenges / Solutions
G2 Consulting is used to working on tight construction schedules, especially knowing that the school bell will ring for new students in the fall. G2 overcame several challenges with the site which included building pad earthwork with high moisture clay soils that occurred in October and challenging subgrade conditions in the Spring for support of floor slabs and pavements.
Smart. Results. Fast.
G2 Consulting Group provided cost-effective solutions to keep the project moving forward during a tight construction schedule and ensured that school began on time.
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.
