Solid Foundation for Grain Storage

Solid Foundation for Grain Storage

URETEK ICR was contacted regarding settlement in two identical 1.5 million bushel grain flat storage buildings.   The overall structure dimensions were 600 ft. long by 135 ft. wide with a Quonset style roof . Below the floor of the storage buildings, a tunnel with conveyance system and a series of aeration tunnels were installed to facilitate moisture control and grain transport.

How to Find Existing Geotechnical Subsurface Information

Geologic map of Southern Florida

So, you’ve landed a job as a Geotechnical Engineer. What now? We all know that before performing any site investigation it is prudent to gather as much information that you can about the project site. There are so many resources out there that can help us get an idea of what the subsurface conditions are so that we can select the appropriate subsurface exploration techniques.

Below is a list of extremely useful sites that can help you gain some indication as to what the subsurface conditions are before planning the subsurface exploration program.

High Octane Solution Solves Raceway Dips

High Octane Solution Solves Raceway Dips

The modern race car being driven on the professional circuit today is an aerodynamic wonder. With mere inches of ground clearance, the car is designed to utilize airflow over the body of the car to force the tires down firmly against the pavement, maximizing traction. The objective, of course, is to safely maximize speed.

Professional race car drivers criticized Texas Motor Speedway regarding“bumps” in the 1.5-mile track between turns one and two. They said that these bumps limited them from running “multiple grooves” on the track (the “side-by-side” racing that NASCAR fans crave) and made it difficult to control cars coming out of turn one.

Texas Motor Speedway responded to this criticism immediately, engaging surveyors to shoot elevations across the track to detect any track deficiencies. It was determined that the unlevel areas were not “bumps”; to the contrary, the problem was, in fact, areas of settlement, dubbed “Dale’s Dips” by the press.

Environmental Data Management for Site Holders

Many site-holders engage a variety of consultants, laboratories, and in-house staff to collect, manage and report their environmental data.

Unfortunately this often results in data being trapped in various pdf reports, GIS layers, emails, excel workbooks, or even in hard copy. This data becomes increasingly difficult and time consuming to manage and retrieve as more data is collected and as legislative reporting requirements become more rigorous.

Stabilizing Wind Energy

Generic wind turbine photo

Recently, URETEK ICR was asked to review a project involving lifting and stabilization of 10 precast transformer pads at a wind farm located in South Dakota.

The pads had settled to varying degrees with 8 of the 10 having settled 1 (±0.5) inch and requiring only stabilization and the two remaining, with settlement in excess of 3.5 inches, requiring lift and stabilization.

Ever get that sinkhole feeling?

Ever Get that Sinkhole Feeling?

It takes planning and good leadership to decide on an effective solution to problems associated with a building asset. Recently, a large wholesale warehouse facility in Cincinnati began to experience large sinkholes across a significant portion of their customer parking lot. Unable to determine the problem at that time, store management was forced to close a portion of the parking lot, inconveniencing their customers. This particular parking lot is unusual in that a drainage system is located directly under the parking lot, consisting of a network of pipes spanning 250 feet in length and 12” in diameter. Joint separations in the underground drainage piping had caused enough soil erosion to create sinkholes in the asphalt. Engineers were concerned that other unknown sinkholes could cave in anytime, resulting in further costly damage, and potentially posing safety hazards to customers.

The Use of the Pile Driving Analyzer for Installing Pile Foundations

Typical pile driving analyzer or PDA setup

[Editor] The pile driving analyzer or PDA is used to measure the response of piles during driving. It was originally developed to analyze pile drivability, but is sometimes used as a substitute for pile static load tests to determine . Mr. Scott A. Barnhill, P.E., Executive Vice President of consulting firm GeoEnvironmental Resources, Inc. located in Virginia Beach, Virginia has seen PDA being used and misused over his 33-year career. In this article, Mr. Barnhill describes pitfalls in relying solely on the PDA for pile capacities, and also describes what PDA is good at and how it can be used successfully. [/Editor]

We must not sell ourselves short: Engineering is an honorable profession

Kleinfelder CEO Bill Siegel

[Editor] Do we as geotechnical engineers and engineering geologists realize the impact of what it is that we do in our professions? Kleinfelder CEO Bill Siegel thinks we need to step back once and a while and look at the significance of our work. In this article contributed to GeoPrac.net, Mr. Siegel describes his observations at more than 50 Kleinfelder offices in this regard. I think I for one will have to work at taking his advice.
