Basement Drainage Design and sump Review

I have a complete package for the basement drainage system—design drawings, shop drawings, and the supporting engineering calculation sheets—and I need a seasoned mechanical engineer to put a sharp set of eyes on them. Technical accuracy is my first concern, but your review must also confirm that pipe sizes, slopes, levels, and drainage pit dimensions truly line up with both good plumbing practice and the project’s stated standards.

Here is how I see the assignment unfolding:

• You study each drawing and calc sheet, checking every pipe run, sump, and invert level for correct sizing, fall, and coordination with adjacent services.
• You flag any mismatches or omissions in a concise comment log, then mark-up the PDFs so the design team can act quickly.
• You wrap up with a brief review memo that summarises non-compliances, proposed fixes, and any further items that should be revisited during construction.

No redesign is needed—just a rigorous, independent verification that the current set is build-ready. Familiarity with common plumbing codes and proven experience in basement drainage design are essential, and you should be comfortable turning this around on a tight schedule.

If this sounds like a straightforward fit for your expertise, let’s get started.
