Retrofitting an existing property to meet current standards rarely involves just one type of work. Structural reinforcement and retaining wall improvements often show up on the same project, particularly on hillside properties or sites where age related deterioration affects both the building and the ground around it.
Why These Two Scopes Overlap So Often on Retrofits
An aging retaining wall showing signs of movement or deterioration is frequently found on the same property as a structure that also needs structural reinforcement, whether for seismic performance or general deterioration over time. This isn't a coincidence. Both problems often stem from the same underlying causes: age, inadequate original design standards, or soil and drainage issues that have worsened gradually over years.
What a Combined Retrofit Scope Typically Involves
Assessing the existing retaining wall's condition and whether it meets current structural and drainage standards
Evaluating the structure itself for reinforcement needs, particularly around foundation and lateral load resisting systems
Determining whether the retaining wall's condition affects the structure's stability, or vice versa
Sequencing the retaining wall work and structural reinforcement so neither compromises the other during construction
Why Sequencing Between the Two Scopes Matters
Reinforcing a structure while an adjacent retaining wall is compromised, or rebuilding a retaining wall while the structure above it lacks adequate reinforcement, can each create risk for the other. A structural engineer evaluating a retrofit needs visibility into both conditions simultaneously, since a decision about the retaining wall's design can affect assumptions in the structural analysis, and vice versa. Handling these as two disconnected scopes, assessed and designed by different consultants without close coordination, tends to produce a retrofit plan with gaps between the two halves of the work.
A Realistic Scenario
Consider a hillside property where an aging retaining wall shows signs of movement, and the structure above it, built to older seismic standards, also needs reinforcement. Addressing only the structural reinforcement without resolving the retaining wall's condition leaves the building vulnerable to whatever caused the wall's movement in the first place. Addressing only the retaining wall without evaluating the structure's own reinforcement needs solves half the problem while leaving the other half unaddressed.
Seiscore works directly with structural engineers of record on retrofit and structural shoring scopes, an approach suited to exactly this kind of combined retaining wall and structural reinforcement project, where the two conditions need to be evaluated and sequenced together rather than treated as separate, unrelated tasks.
Questions Property Owners Should Ask
Has the retaining wall's condition been evaluated alongside the structure's own reinforcement needs, or separately?
How will the two scopes be sequenced to avoid compromising stability during construction?
Is one team coordinating both the retaining wall and structural reinforcement work, or are they being handled independently?
Conclusion
Retaining wall deterioration and structural reinforcement needs frequently show up together on aging properties, and treating them as connected problems, rather than separate line items, tends to produce a retrofit that actually addresses the underlying stability of the property. A property owner evaluating this kind of project is best served by a team that can assess both conditions together and sequence the work so neither scope undermines the other along the way.
