GCI provided geotechnical services during design and construction phases for this 330 feet wide by 600 feet long clear span athletic facility at Kenyon College. The facility includes two below grade levels, an Olympic-sized pool and a 400-meter track. Column loads ranged from about 200 to 660 kips. Geologically, the site was underlain by alluvial deposits associated with the Kokosing River. Foundations included a combination of shallow spread footings and drilled shafts.----Photo courtesy of Kenyon College

When operational, the Greenville plant will be able to produce 110 million gallons of ethanol a year. GCI provided comprehensive geotechnical services during design of the ethanol plant facility. Recommendations included ground improvement techniques to stabilize a compressible clay mantle and improve bearing capacities up to 7,000 p.s.f. During construction, GCI provided full-time monitoring and testing of soils, concrete, steel, and foundations (including Geo-Piers®).

When completed, the $35 million project will include two buildings totaling nearly 200,000 square feet. The site is underlain by highly compressible peat and soft alluvial soils and was filled for use as a staging area during construction of Polaris Parkway.  Working with the design team and foundation contractor, GCI recommended the use of auger-cast piles, designed to account for downdrag loads as the fill continues to settle over the underlying compressible soils. During construction, GCI monitored two pile load tests, installation of 500 production piles, and construction of pile caps and grade beams. Our NDT department provided comprehensive inspection of structural steel, steel connections, and fireproofing.----Photo courtesy of Equity, Inc.

This regional shopping mall with over 2 million square feet of retail space, including six major anchors, opened in 2001.  The project included mitigating wetlands, rerouting waterways and installing several ConSpan structures, placing fills in excess of 20 feet including steep geogrid reinforced slopes, and constructing a new City road.  Due to the fast track schedule, GCI advised client regarding use of chemical additives (to dry soils) and geogrids (to stabilize soils) to keep the project moving forward and meet the 13-month construction schedule.  GCI has remained involved with development of many outparcels surrounding the mall and in the subsequent mall redevelopment.----Photo courtesy of Glimcher Realty Trust

This upscale office development consists of three 5-story office buildings fronted by commercial space. The site, which is located in a river valley setting, is underlain by variable alluvial soils including upper level compressible clays. GCI provided geotechnical services during design and construction of the project. Surcharge methods were used to improve the load carrying capacity of soils and reduce post-construction settlements.----Photo courtesy of Daimler

The Greene is a lifestyle center development constructed on 75 acres of undeveloped land in the Dayton suburb of Beavercreek, Ohio. The development includes one- and two-story retail buildings, a movie theater, office space, and apartment units above some retail areas. The center also includes three cast-in-place, post-tensioned parking garages. GCI provided geotechnical engineering services during design phases and construction materials testing services during construction. Phase I opened for service in the fall of 2006; Phase II is ongoing and will open in fall of 2008.

This luxury apartment and retail/commercial lifestyle center is located on the south side of Charlotte. The residential structures are three-stories with slab-on-grade, while the retail structures range from 1- to 2-stories with slab-on-grade. Portions of the 10+-acre property required cuts of up to 15 feet to reach desired grades, extending the site into the underlying partially weathered rock. Additionally, portions of the property abut wetlands, which required constructing up to 26-foot high reinforced earth retaining walls to extend the buildable land while keeping a “natural” look to the slope. GCI provided recommendations for construction based on subsurface explorations during the design phase and construction observation and testing services during construction.

This five–story office building was constructed over a closed and capped former municipal landfill. GCI provided comprehensive geotechnical services during the design phase of the project. Partial displacement augered pressure grouted piles were selected to minimize the potential for cross-contamination and reduce the volume of drilling spoils that would have to be handled. During construction, GCI provided full-time monitoring of site grading, pile load tests and production pile installation, as well as concrete, steel, and asphalt.----Photo courtesy of Daimler

GCI provided geotechnical services during the design phase for the 800,000 square foot warehouse, including evaluation of a ground water recharge system to handle runoff. To accommodate an aggressive construction schedule, we staffed the project with two full-time technicians and part-time support to observe a range of construction operations including mass grading, foundations, slab construction, steel erection, utility installation, and stormwater runoff protection monitoring.----Photo courtesy of Duke Construction
