Simone Garozzo - The Most Important Drawing
Case Study 2: The Most Important Drawing Wasn’t on the Plans
One Missing Drawing Could Have Delayed the Entire Project
A builder forwarded the civil stormwater drawings and requested a drainage schedule for the project.
During the review, it became apparent that one critical area, the car wash bay, wasn’t detailed within the civil package. The plans referenced the hydraulic documentation for the treatment pit, wash bay drainage and pumping station, meaning the information required to specify the drainage products simply wasn’t there.
Rather than issuing an incomplete quote or asking the builder to coordinate between multiple consultants, I contacted the hydraulic engineer directly and obtained the missing design information from the source.
The information required to specify the drainage products simply wasn’t there.

With the hydraulic details confirmed, the correct drainage products could be selected based on the required flow rates, loading classification and application, ensuring the specification matched the engineer’s intent before procurement.
The builder avoided unnecessary RFIs, the plumber received the correct information sooner, and the engineer wasn’t drawn into a long chain of emails.
The result
- Identified missing hydraulic information before the quoting stage.
- Coordinated directly with the hydraulic engineer to obtain the required specifications.
- Eliminated unnecessary back and forth between the builder, plumber and consultants.
- Ensured the correct drainage system was specified the first time, avoiding delays and potential variations.
Key Message
Plans don’t always tell the whole story. Understanding where to find the missing information is just as important as understanding the products themselves.
