Salas O’Brien provides post-design services; specifically, multi-disciplinary engineering support during the pre-construction, construction, and post-construction project phases.

We ensure design-bid-build and design-build projects are completed on schedule and budget. We serve as owner advocates to ensure newly constructed systems meet design intent and mission requirements. Our post-design services during construction ensure that facility assets achieve cost-efficient operation. Our services include:

Salas O’Brien delivers safety solutions that mitigate risk to workers from workplace environments and industrial processes. We provide occupational safety services to safeguard employees from workplace hazards under the guidance of our certified safety professional (CSP). Our system safety capabilities consist of engineering analysis of industrial processes to identify safety hazards and recommend mitigations that reduce incident risks to client and regulatory acceptable levels.

Salas O’Brien’s clients trust us to provide engineering services that sustain their existing real property portfolios. We provide asset management services such as facility condition assessments, cost segregation studies, FCI calculations, deferred maintenance calculations, FAR and non-FAR based procurement solutions, and other services.

Salas O’Brien provides occupational safety services to protect employees from workplace hazards, guided by our certified safety professional (CSP). We conduct engineering analyses to identify safety risks in industrial processes and recommend mitigations to meet client and regulatory standards.

Salas O’Brien performs investigation and analysis of failures, damages, or defects in structures and materials. Our experts determine causation, whether due to natural events like storms, fires, and earthquakes, or human factors such as construction errors or design flaws. We assess the integrity of buildings and other structures, machinery, building systems, and infrastructure, providing detailed reports that are often used in insurance claims, legal disputes, and risk management. Our work helps clients understand the root causes and guides them in making informed decisions about repairs, replacements, and preventive measures.
