Major Infrastructure Design Disputes

Urban Transportation System: Managed a team investigating an entitlements dispute regarding civil and structural engineering design changes for a new underground and elevated metro system, including stations and viaducts. Estimated the level of effort required to execute changes. Provided sworn expert testimony.

Urban Transportation System: Managed a team investigating claims that an engineer's tender design was insufficient to enable a contractor to correctly prepare their bid on an EPC contract for a new metro system, including stations and ancillary facilities.

Underground Transportation System: Evaluated the earthquake intensity used in the design of an underground metro system in a high-seismic area. Evaluated the accuracy of a numerical model used by the designer to estimate behavior of the system during earthquakes.

Underground Metro Station Shoring Design: Evaluated the shoring and reshoring design of an underground metro station to determine if the design complied with codes and standards, and if changes to the design requested by the contractor were required for the design to comply.

Seismically Isolated Bridge: Conducted a performance-based assessment of the seismic collapse capacity of a bridge in a high-seismicity area, including performing incremental dynamic analysis to determine the probability of collapse during a design intensity earthquake and the lifetime probability of collapse. The analysis results informed whether the bridge, as designed, posed a safety risk.

Airport: Evaluated the structural design of the main terminal building and ancillary facilities at a major airport, including the capacities and deflections of slabs, beams, and curved columns and floor vibrations requirements.

Energy Facilities

LNG Facility: Audited the design performance of an EPCM contractor on a large LNG plant development project on behalf of a major oil and gas company.

Solar Plant: Analyzed the expected energy output of a solar thermal power plant in observed weather conditions relative to baseline models of the facility in a standard meteorological year. Results were used to calculated performance payments stipulated by the EPC contract.

Failure and Damage Investigations

Bridge Demolition: Investigated the cause of damage to bridge piers during the explosive demolition of the superstructure. Performed applied element analysis of the demolition sequence under numerous hypothesized scenarios and validated analysis results against field conditions.

Bridge Dismantling: Investigated whether an engineer met the standard of care in their design of the dismantling sequence of a long span bridge where a component failed during the dismantling. Evaluated alternative means of felling the structure. Named expert, but the case settled prior to my testimony.

Collapse of a Parking Deck: Investigated the partial collapse of a parking deck, including a comprehensive evaluation of the field conditions of the remaining portions of the parking deck.

Failure of a Railing: Investigated the cause of failure of a railing during a concert, which resulted in numerous injuries.

Scaffold Collapse: Investigated the cause of collapse of scaffolding during a windstorm.

Post-Earthquake Damage Assessment: Investigated alleged earthquake damage to numerous school building to determine the cause of damage and the impact of an earthquake on the future performance of the buildings during earthquakes.

Earthquake-Resisting System: Investigated alleged reduction in the earthquake-resisting capacity of a tall building in a seismically active area due to water leaks. Performed finite element analysis of the building under numerous damage scenarios and earthquake intensities.

Post-Hurricane Damage Assessments: Performed many investigations into damage to buildings during hurricanes, including distinguishing between damage caused by wind vs. water in residential and commercial structures, and distinguishing between new and pre-existing conditions.

Adjacent Construction Investigations: Performed many investigations into damage to buildings caused by adjacent construction activity, such as: evaluating whether damage to a high-rise condominium was caused by dewatering at a nearby site; investigating the partial collapse of a foundation during underpinning; investigating the collapse of a ceiling while vibratory equipment was in use; evaluating the likely origin of damage to a church with multiple adjacent structures under construction.

Risk Analysis and Design Assistance

Plutonium Facility (PF-4): Developed numerical models for developing testing criteria for assessing the performance of a critical component in a US Dept. of Energy plutonium storage facility subjected to earthquakes. Provided expert peer review services for earthquake ground motion selection.

Climate Change Risk Assessment: Developed and implemented a probabilistic framework for identifying the vulnerability of a large utility company's power transmission assets to climate change, including changes in intensities of precipitation, temperature, wildfire, and sea level rise, using performance-based engineering techniques. The effort included leading the development of fragility curves and the analysis of aging and degradation mechanisms to assets such as wood poles, steel towers, conductors, underground structures, foundations, and insulators. Hazard curves relating intensity of climate hazards to their frequencies of occurrence were developed from downscaled climate models to allow for, in conjunction with the fragility curves, calculations of annual failure rates of assets. Mitigation recommendations were developed based on the analysis results.

Quantitative Risk Assessment: Developed a quantitative risk assessment framework to evaluate wood poles and steel towers subjected to seismic loads and earthquake-induced landslides for a large utility company. Led the technical development of a probabilistic framework for assessing the risk of contamination-induced flashover of insulators.

Seismic Isolation: Provided advice and guidance for the design of a seismically isolated light frame house located one mile from the San Andreas Fault, including performing nonlinear response history analysis of the structure, developing details for isolator units, developing load protocols for prototype and production isolators compliant with ASCE7 requirements, and coordinating with peer reviewers.

Battery Mounting: Provided advice and guidance for mounting solar batteries to structures in high-seismic areas, including developing conceptual connection details.
