Construction Services

AKA provides a full range of geotechnical construction observation and testing services in support of our clients’ projects. Observation and testing during construction is a critical final link in a process that starts with the geotechnical investigation. All geotechnical investigations require the use of engineering judgment to evaluate likely variations in subsurface conditions between a finite number of investigation points. Key assumptions with the potential to affect the project design need to be confirmed during construction. Construction observation and testing provides a means by which unanticipated conditions can be addressed in a timely manner and verifies that the project was constructed in accordance with the plans and specifications. Key construction observation and testing services that we provide include:

• Review of geotechnical construction submittals and requests for information
• Laboratory testing of proposed geotechnical materials
• Laboratory compaction curves to determine maximum dry density and moisture content of fill materials
• In-situ testing of fill density and moisture content
• Observation of completed footing investigations
• Observation during drilled pier and driven pile installation
• Observation during the installation and testing of tiebacks and tiedowns
• Observation of surface and subsurface drainage installations
• Observation during excavation, keying, and benching
• Observation during fill placement, subgrade preparation, and proof-rolling
• Observation and testing services during ground improvement
