• Wall Assemblies
• Existing Drawings vs. As-Built Conditions

Engineering for Existing Buildings vs. New Construction

The core distinction lies in the need to understand existing conditions in renovation projects. Unlike new construction where the design starts from a clean slate, existing buildings require a thorough assessment of the current state.

The Role of Forensic Engineering

Forensic engineering plays a crucial role in renovation projects. It involves investigating and analyzing the existing conditions of a building to understand its current performance and identify any issues.

Existing Conditions Assessment: A Detailed Look

• Understanding Current Performance: Forensic investigation helps determine the current performance of the building, including its MEP systems. This assessment identifies areas that need upgrades or improvements.
• Wall Assembly Investigation: A key aspect of forensic engineering is examining wall assemblies to understand their composition and condition. This is crucial for making informed decisions about renovations.
• Addressing Discrepancies in Existing Drawings: The speaker emphasizes that existing drawings are often inaccurate, with a "95%" discrepancy rate between drawings and actual construction. Therefore, forensic investigation is essential to verify the actual conditions.

Data-Driven Design

The information gathered through forensic investigation serves as critical data for the design phase of the renovation project. This data informs decisions about upgrades, modifications, and overall project scope.

Notable Quotes:

• "You look at those drawings and that's not how it was built 95% of the time, right?" - Highlights the unreliability of existing drawings.

Conclusion

Engineering for existing buildings necessitates a forensic approach to accurately assess existing conditions. This involves understanding current performance, investigating wall assemblies, and verifying information against potentially inaccurate existing drawings. The data gathered through forensic investigation is then used to inform the design phase of the renovation project, ensuring that the upgrades and modifications are based on a realistic understanding of the building's current state.
