Smale Riverfront Park at the Banks

October 1st, 2015

Location: Cincinnati, Ohio
Client: Cincinnati Parks
Services: Geotechnical

THELEN performed the geotechnical services for the Smale Riverfront Park. Our services were performed in different phases for various portions of the project. The following are the most recent 2 phases of the project: Site Walls and Boat Dock: The project site is located along the north edge of the Ohio River between the John A. Roebling Suspension Bridge and the Great American Ball Park in Cincinnati, Ohio. THELEN’s services consisted of performing nineteen (19) test borings – eleven (11) of the borings were advanced from a barge on the river, and the remaining eight (8) borings were performed on land, laboratory testing and preparation of a report of conclusions and recommendations.

Prior to the geotechnical report, the proposed development was to consist of a 1,400-foot long retaining wall supported on piles and a 1,000-foot long boat dock. The proposed retaining wall will begin at the river’s edge. A structure similar to the serpentine wall will then step up from the river’s edge wall to a walkway. A ramp will be located in the mid portion of the project and additional serpentine steps will be located to the west and east of the ramp section. A relatively flat walkway or a short, sloped section will then be constructed at the top of the existing retaining wall.

The proposed grading was to require up to 11 feet of newly placed fill in the portion of the walkway immediately adjacent to the river’s edge wall. It is noted that there are two (2) existing retaining walls to the north of the majority of the proposed river’s edge wall. The closest existing retaining wall consists of a large concrete pile-supported retaining wall and the upper northernmost retaining wall consists of a smaller concrete spread-footing cantilevered retaining wall. The proposed grading will require portions of those walls to be cut off near the western end of the proposed rivers edge wall. The existing river bottom will be dredged to create a minimum depth of water between the river’s edge wall and the boat deck.

Lot 22: This portion of the project involved constructing an elevated structural slab over an existing parking lot that is near the elevation of Mehring Way. The elevated structural slab will be at or near the elevation of Theodore M. Berry Way and the north approach of the Roebling Suspension Bridge, and will support a carousel and fountain. Additionally, the eastern half of the elevated slab will support approximately a 4-foot depth of soil for planting trees. At the west end of the structural slab will be a stairway to permit pedestrian traffic from the elevated slab and Theodore M. Berry Way at the northwest corner of the project site to Mehring Way at the southwest end of the project site. We understand that the lower level area beneath the elevated slab will consist of a reception hall, conference and office rooms, mechanical/electric control equipment, and storage.

THELEN’s services consisted of performing six (6) test borings, laboratory testing and preparation of a report of conclusions and recommendations. During construction of the Park phases, we have performed construction review services including augercast pile review, soil and concrete testing.

New Busch Stadium

August 14th, 2015

Location: St. Louis
Client: St. Louis Cardinals/Gateway Parking, LLC
Services: Materials Testing

Overview
Geotechnology and its team of City Design Group and TSi Engineering provided comprehensive materials testing, soils testing and ICC Special Inspections for the St. Louis Cardinals’ new baseball stadium. Geotechnology, accustomed to coordinating complex, long-term projects and working easily with changes, managed the team for the design-build project. The ballpark replaced the original Busch Stadium structure, which sat immediately to the north and partially overlapped the new project site in downtown St. Louis. Designed by HOK-Sport Venue and Event, the stadium provides seating for 46,000 people, a street-level “free viewing” area, and upgraded amenities to make a ballpark outing truly enjoyable for the whole family.

As part of the over $1 million contract, the Geotechnology team performed construction materials testing and ICC special inspections of soils, cast-in-place and precast concrete, masonry, waterproofing, fireproofing and structural steel. Approximately 35% of the contract is attributed to non-destructive testing by Geotechnology. City Design Group conducted field and laboratory testing of concrete, mortar and grout. TSi performed field
and laboratory testing of soils and aggregates, and field testing of soil and rock compaction. The team accommodated a fast-track construction schedule and completed the project under budget. The new stadium opened on time for the 2006 season.

Lakeview Commerce Center – Building III

April 15th, 2015

Owner: Panattoni Development Company
Client: Brinkmann Constructors
Location: Edwardsville, Illinois
Services: Construction materials testing, special inspections

Scope of services: The project consisted of a new single-story 400,000 square foot tilt-up concrete panel warehouse. The building was designed to be founded on shallow column and continuous foundations with a slab-on-grade. Site improvements consisted of an asphalt-surfaced and concrete-surfaced parking lot, drive lanes, and roadways. Geotechnology provided construction materials testing for soil, aggregate, concrete, hot-mix asphalt, floor flatness and levelness, shallow foundations, reinforcing steel, and structural steel.

Problem: The project site consisted of potentially expansive, high plasticity clay soils.

Solution: Instead of removing and replacing the unsuitable soil with a low plasticity soil, the owner elected to treat the existing soil with code-L, a by-product of the lime manufacturing process. Code-L is blended with the soil at predetermined percentages causing a change in the soil’s chemical and physical properties. This reaction changes the soil plasticity and subsequently reduces the swelling potential.

Benefit: By adding code-L to reduce the plasticity of the soil, there is a reduced risk of the soil swelling, which could lead to damaged foundations costing the owner money. Additional benefi ts include increased soil strength and reduced moisture content.
