What's the best way to assess and mitigate risks associated with deep excavation?
With more than 50 years of experience in addressing complex scientific, engineering, and construction challenges, Exponent is uniquely qualified to lead deep excavation evaluations and failure investigations. Although excavations are regulated by federal, state, and local building codes, numerous factors create challenges when developing a site, including design and construction errors and omission, construction accidents, striking unknown utilities, differing site conditions, and unforeseen natural events.
Design and construction typically involve many steps, including site characterization, design of excavation support systems, specification of responses to construction difficulties, preconstruction surveys of adjacent properties and utilities, field observations and monitoring during construction, and excavation installation. Because, in an urban environment, deep excavations may damage adjacent properties, the consequences of inadequate performance can be amplified. Exponent's multidisciplinary team can help with challenges pre- and post-excavation.
services
For 50+ years, we’ve thrived on solving unstructured problems that require bespoke solutions. Some of our services include:
• Pre- and post-construction condition surveys
• Emergency response in the event of a failure
• Analysis of the causes of failure, and of the nature and extent of damage to real property, cost analysis, delay impacts, and acceleration
• Evaluation of differing site condition claims
• Evaluation of the suitability of temporary shoring and dewatering systems
• Installation and monitoring of geotechnical instrumentation and building monitoring devices to measure ground and building deformation
• Analysis of building or ground deformation
• Vibration analysis, including continuous monitoring of construction-induced vibrations
• Evaluation of construction activities and response to construction difficulties
• Act as a third-party reviewer to communicate technical issues and risks to interested parties or to review proposed excavation plans
