The Lower San Joaquin River Phase C-2 project is part of a larger flood-risk-management program to reduce flood risk in the North, Central, and South Stockton basins in California. Phase C-2 focuses on the Calaveras River Right Bank levee system and includes reaches totaling approximately 23,130 feet of levee between the San Joaquin River confluence and North El Dorado Street. The project advances levee improvements that meet United States Army Corps of Engineers (USACE) and non-federal sponsor design requirements while supporting long-term flood resilience for the Stockton community.

A new advanced nuclear materials research facility under design and construction is a flagship initiative at a major international nuclear site. This state-of-the-art facility will house hot cells, radiation laboratories, and office space essential for advanced materials and fuels testing and examination. The primary implementing organization had completed 50 percent of the preliminary design and commenced initial site preparations in anticipation of full-scale construction. Given the scale, complexity, and strategic importance of the facility, the governmental oversight entity engaged us for an independent assessment of the project’s cost estimates, risk profile, and schedule maturity. This assessment aimed to support a crucial funding sanctioning decision that would enable progression to the detailed design, construction, and commissioning phases.

Longenecker & Associates, a Geosyntec Company, recently conducted an independent review of the contractor assurance system (CAS) at a prominent national laboratory on behalf of the laboratory’s managing entity’s board of directors. The review team comprised subject matter experts from our firm and national laboratory members. The objectives of the review were to assure a key federal oversight department that the laboratory is operating in compliance with its prime contract and is using its CAS processes, metrics, and governance bodies to achieve this. We identified gaps in understanding, implementation, and effectiveness.

A major international organization is undertaking design and construction of a new major nuclear materials facility that will become the backbone of their research and development infrastructure and deliver nuclear science and technology programs. The facility is also important to the organization’s ambition to penetrate new international markets and add capabilities to better meet the needs of their federal and commercial customers.

The federal owner of the facility had become concerned about the project delivery approach and the project’s key performance indicators (KPIs), which had been trending down over three consecutive quarters. As a result, the client engaged L&A, a Geosyntec Company, to conduct an independent review of the project’s position on quality management, health and safety, and cost and schedule.

A premier United States Department of Energy multidisciplinary science and engineering national laboratory engaged Longenecker & Associates, a Geosyntec Company, to conduct an independent review of its event management process. We reviewed the abnormal and unplanned events that are investigated, analyzed, and resolved, with an emphasis on integrating human performance improvement (HPI) principles across event response activities. The project aligned with the client’s mission of operational excellence, safety, and continuous performance improvement across its diverse research and operational units.
