The practice of structural engineering is increasingly complex, and the input of an independent, experienced structural engineer can be helpful to a project.  Erickson Structural provides third party reviews of work performed by other structural engineers.  We provide these services to other structural engineers in need of constructive feedback or “a fresh set of eyes,” and to construction industry professionals, such as owners, contractors, architects, insurers and attorneys, looking for a second opinion.  We are especially well-suited to review complex structural renovation, evaluation, repair and diagnostic projects.

Our experience providing peer reviews is supplemented by our work conducting structural plan review services on behalf of jurisdictions.  We review the plans and calculations submitted for permit and determine what modifications are appropriate to satisfy applicable structural building code provisions.  From our forensic investigative work, we have seen “what not to do” and apply those lessons learned to our peer review efforts.  Having submitted peer reviews of our own work, we provide our feedback with tact and objectivity.

We can review structural plans and calculations, written reports, proposed investigative and diagnostic testing plans, and the results of those tests, and similar efforts.  Our review can occur incrementally as the project evolves, or at a discreet milestone to coincide with the generation of work product.  Our comments and recommendations can be provided verbally or in writing.  When needed, we can conduct our work confidentially and we do not publicize our peer review projects.

Erickson Structural is adept at identifying existing structural conditions, presenting a range of design options, and working closely with clients to develop cost-effective, value-filled solutions for building expansions and renovations. Our experience will help you navigate smoothly through the myriad of issues, including seismic issues, which may result from building modifications.

• Identify existing structural conditions
• Develop as-built structural drawings
• Assess applicable code issues
• Offer creative design options and guidance
• Conceive structural upgrade plans that minimize disruption to existing building occupants and operations
• Produce thorough, clear and detailed bidding and construction documents and supporting calculations
• Assist the design team, contractor and owner throughout construction

Erickson Structural is proficient at performing structural analyses of existing buildings. We understand the unique design and construction issues inherent with existing (and often occupied) buildings. Our experience with a wide range of building types, owner requirements, seismic design standards, and advanced analysis and design techniques, enables us to efficiently identify structural issues that might exist.

• Review original construction documents
• Observe, document and analyze existing structural conditions
• Assess applicable code issues
• Design structural system replacement, retrofit and strengthening
• Develop and design materials testing plans
• Review and produce structural calculations

Erickson Structural is frequently consulted to determine the causes of unexpected or substandard performance of building structures. We provide consultation, investigation, structural analysis, destructive and non-destructive testing, technical reports, and can serve as an expert witness. We also assist with the development of remediation designs, remediation cost estimates and provide engineering support services during the construction phase.

We are often called upon to assist with the investigation of insurance claims that involve structural loss. We observe and document the extent of the damage, conduct tests or perform subsurface investigations, establish the proximate causes of the damage, recommend repairs and prepare a final report usable by the various parties involved in the claim.

• Perform proximate cause investigations
• Assess construction defects
• Assess design errors
• Assess materials defects
• Develop testing and monitoring systems
• Review design and construction documents
• Determine extent of damage
• Prepare schematic remediation designs suitable for scoping and pricing
• Prepare final remediation designs suitable for permitting, bidding and construction
• Provide assistance during the remediation phase
• Provide expert witness services

Erickson Structural investigates buildings exhibiting structural distress due to age, climate, wear and usage, natural catastrophes (including fires, soil movement and water-induced structural damage), overstressed structures, and original design or construction flaws. Our investigations generally conclude with a formal report summarizing the distress issues and their causes. We also provide recommendations for a range of possible repair options. Once an appropriate solution is selected, we work closely with building owners, cost estimators, design team members, contractors, insurance carriers, and attorneys to develop thorough documentation outlining necessary remediation.

• Perform initial building investigation
• Perform building usage/wear research
• Review construction documents
• Investigate alleged design errors and construction flaws
• Develop and design materials testing plans (destructive and non-destructive)
• Perform forensic analysis of existing building materials, structural systems, and construction techniques
• Review and produce structural calculations
• Provide litigation support
• Report findings and recommendations

Erickson Structural is skilled at overcoming the challenges associated with seismic evaluation and strengthening of existing buildings, whether as a planned or phased upgrade process, or under sudden, emergency response conditions.

We understand the unique design and construction issues inherent in older buildings. Our extensive experience with a wide range of building types, owner requirements, seismic design standards (including ASCE 41 and ASCE 31), and advanced analysis and design techniques enables us to efficiently identify and develop the right solution for each project.

Likewise, we can provide knowledgeable, rapid reconnaissance shortly after a seismic event to provide consultation and address the need for emergency structural repairs. We are ATC 20 trained and certified. Representative Services:

• Observe, document and analyze existing structural conditions
• Review building codes and assess compliance
• Develop customized structural system rehabilitation options and recommendations
• Design structural system replacement, retrofit, and strengthening
• Design equipment anchorage and bracing
• Develop phased seismic upgrade designs to minimize disruption and maximize project value
• Perform advanced seismic analyses
• Post-event emergency response
