TSi performed a subsurface exploration and geotechnical engineering evaluation for the Taxiway C project located at the Spirit of St. Louis Airport. TSi’s geotechnical investigation provided engineering characteristics of the soil along the planned Taxiway C expansion. TSi provided geotechnical recommendations for the design and construction of the taxiway. TSi’s evaluation and final report was utilized to determine the thickness and composition of the existing Taxiway C pavement section at the western end of the project. TSi scope of services included a site reconnaissance and a review of the geology of the project area; a drilling program consisting of five borings to a
depth of five feet, and laboratory testing.

Client: St. Louis County
Location: Chesterfield, Missouri

TSi provided geotechnical recommendations for the design of
pavement improvements for two separate areas of the Spirit of St. Louis Airport. One area is the apron for a hangar west of Beechcraft Avenue and the other is an access road at the eastern end of the main runway. The improvements could involve replacement or overlay of the existing pavement, depending to some extent on the conditions encountered in three borings drilled to explore the existing subgrade. Recommendations were provided for a design CBR value, specific construction procedures, and to address the possible need for sub-drains.

Client: St. Louis County
Location: Chesterfield, Missouri

As a subconsultant to the prime engineering firm, TSi completed subsurface investigation and geotechnical engineering evaluation for the new maintenance facility. TSi completed four test borings
at the project site, ranging from 5 feet to 20 feet in depth. The borings were drilled with a track-mounted rotary drill rig using hollow-stem auger drilling methods. Standard penetration test (SPT) and Shelby tube samples were recovered from the borings. SPT samples were recovered using a 2-inch outside-diameter, split barrel sampler, driven by an automatic hammer. Shelby tube samples were obtained in accordance with ASTM D 1587. TSi also directed and observed field exploration procedures, collected and classified soil samples in accordance with ASTM D 2488, and prepared reports.

TSi directed a subsurface exploration that collected bulk samples of the near-surface soils at the site. A laboratory testing program evaluated the benefits of stabilizing the subgrades under the new taxiway pavements using lime or fly ash. TSi then completed a geotechnical report summarizing the results of these tests. During construction, TSi had a full time technician on site observing fill placement, chemical stabilization of on-site soils, placement of the drainable cement treated base, and concrete placement for the new taxiways.
