Geotechnical Engineering Services

A critical component of the engineering design process for buildings, roads, utilities, structures, or essentially anything built on the earths’ surface, is a thorough understanding of geotechnical issues, before ground is broken. A major cost implication can arise when these issues are not well-understood or planned for prior to construction. At CTI, we design solutions to geotechnical issues, such as unstable soil conditions, with constructability and construction costs in mind.

Balancing design factors of safety with costs is not always straightforward; however, this is a key consideration for our geotechnical engineers. In doing so, we develop innovative solutions that save our clients money. CTI can determine and define many "unknowns" related to the surface and subsurface conditions of the site. This provides project planners with the data necessary to identify the costs of these phases, including those associated with the existence of adverse site conditions that otherwise may have gone undetected or may not have been discovered until the construction phase.

Our involvement does not end in simply identifying the surface and subsurface conditions. Our expertise in the geotechnical engineering field allows us to take an active role in assisting designers and planners in the formulation of the most economical foundation systems, pavement sections, de-watering systems, excavation slopes, or other soil related aspects for a project.

EMBASSY SUITES/ONE NORTHWEST PLAZA CTI provided geotechnical engineering support to construction of two ten-story commercial buildings. In addition to geotechnical engineering during the design phase, CTI provided quality control and inspection services during the construction phases to ensure that contact specifications were being followed by the Contractor.
