Alpha & Omega Group has provided structural condition assessments of several historic buildings during the last few months. Our work has brought us around the state and even as far as Michigan as we have inspected churches, bridges, and lighthouses to assess the condition of the structures. But what is a structural condition assessment, and how important is it to preservation and repair efforts? Structural condition assessments are a vital first step to any project involving repairs, particularly for older and historic buildings.

What is a structural condition assessment?

A structural condition assessment (SCA) is a special inspection that uses both data and observation to determine the condition of a structure based on the comparison of existing records and current observations. Often structures face challenges due to outdated construction methods, the deterioration of materials, or foundation settlement. Because of this, comparing the current state of the structure to when it was originally built can provide more information than observation alone.

How is it done?

For an SCA, the A&O Team first reviews as much information about the structure as possible. They look over old blueprints, previous inspection notes, and information about the location of the structure to make the most informed assessments even before the project starts.

Once this review is done, the on-site assessment begins. The team visits the project site where they carefully inspect the structure. If they are examining a bridge, the team will make sure that the superstructure, substructure, and decking appear to be sound and look for any signs of deterioration, decay, or wear. If the team is inspecting a building, then the foundations, roof, and any unique elements are checked for cracking, deflections, and signs of damage. These observations are all noted and compared with existing documents, with pictures to provide clear references. The observations, photographs, and any recommendations for repairs are included in a written report and sent to the client for review and next steps.

When is it necessary?

While bridges receive regular, scheduled inspections due to their importance and daily use, the SCA is usually the first step in a larger project. Often, signs of decay, settlement, or structural deterioration are noticed by the owners themselves. In these cases, the main focus is to determine the full extent of the damage and the best options for repairs and prevention of further damage. Sometimes, the client is deciding if needed repairs are even possible. In the case of our lighthouse projects, the US Coast Guard requested assessments to see if the structures could be restored, stabilized, or if some structures should be demolished. Special attention was given to the feasibility of repairs, and the final reports include discussion of potential repairs as well as potential demolition and repair costs.

Conclusion

Structural condition assessments give a snapshot of a building’s current condition, determine if repairs are necessary, and map out what those repairs will likely cost. With this information, owners can decide how to forward confidently with the design and construction phases of their projects. The A&O Team is proud to be able to arm our clients with the information to take that first important step.
