Geotechnical Construction

Geotechnical Construction

Since 1967, Jaca & Sierra Engineering, PSC has been an industry leader in providing geotechnical investigations and consulting for dealing with challenging subsoil conditions in Puerto Rico and the Caribbean Region. Within the past 10 years, Jaca & Sierra has ventured into completing projects as geo-structural construction specialty subcontractor. Most of these projects have been performed as a value engineering or turn-key design build delivery.

Our quality management structure on drilling for geotechnical, environmental and water well applications combined with our geotechnical consulting experience and quality control expertise provides our firm with a strong background for construction of geo-structural applications such as micropiles, retaining walls, ground anchors, grouting and rock anchor projects.

As geotechnical engineers, we take great pride on being able to provide solutions to our clients and delivering custom designed-built geo-structural applications. We can also bid on geotechnical construction designed by others.
