Structural:
Five 5-gallon buckets of "shiners" hauled off of a 35,000 SF wood-framed store roof. Structural engineer saw them from below. Contractor had to drive them all back out, renail, then pull out all the nails sticking out. That way they could see where not to fire their nail guns.
Someone checked one nut for tightness at an exposed timber-franed canopy. The nut, washer, and 2" of threaded rod came off in his hand. Rod was in a hole about 1-1/2" deep. Bolts from other side were about 2" long, also into shallow holes. Someone could not be bothered to drill through the beam and buy bolts the correct length.
HVAC
Employees in a just-constructed branch bank complained of new building smells and other aromas. Detailed investigation included removing supply grille on a sidewall diffuser. Sitting in the duct was half of someone's sandwich from months before.
Architect/ HVAC
20+ years after completion, a piece of mechanical equipment in a penthouse needed to be replaced. GC's PM was surprised to find it had to be totally dismantled to take it out the 36" door into the room. Apparently it was installed before building walls and roof were completed. Mechanical engineer didn't tell architect about sizes from future replacement. Architect didn't ask.
I was the architect. GC's PM was my son, whose career is in construction management. Some good-natured teasing followed.
Replacement unit was carried up stairs in sections and assembled.

This is a great question and I can't wait to see the response from others.
For MEP items (depending on construction progress):
- Fixtures mounted securely, square, and plumb with no leaks. Once had an entire sink rip away from the wall on final inspection. Mounted directly to the metal studs with self tapping screws and no blocking.
- Pipe / Duct insulation matches specs for thickness and material. No mysterious stains or damaged sections.
- All fire, natural gas, utility piping is either painted the correct color or marked with directional indicators (or both).
- Floor, sink, and shower drains flow freely. Once had concrete polishers knock a cover off a floor drain and fill it with wet grind concrete sludge.
- Pipe and duct penetrations sealed and / or insulated.
- HVAC or building controls recognizing all components and communicating to network (if applicable)
- Maintenance and inspection plates on equipment (filter change housings, VRF covers) are accessible and facing the correct direction / orientation.
- No metal shavings, debris, or dust contaminants inside ductwork. Once had an HVAC contractor leave registers and louvres uncovered while other trades were working which allowed drywall dust and sawdust into the intake.
- All filters are installed / new prior to turnover.
- All equipment grounded to bus bar or grounding ring including lightning protection system.
- Breakers labelled and not tripped or tagged.
- Conduit, wire, piping etc not in contact or rubbing where vibration could cause damage.
- All shipping / packing / bracing dunnage has been removed from equipment.
- Emergency lights work in test mode.
I'm sure theres more out there.

I have been struggling with teaching green individuals items to look out for when on-site, particularly in the MEP and Structural realms. This is more so to let the other disciplines know of items they may want to check out for when they are on site; e.i. splines of the PT bolts being snapped or not. I've other Mechanical, Electrical, and Structural Engineers put eyes on architectural items as a courtesy in the past, and it has been wonderful to have the additional set of eyes, especially on different days, with how quickly construction can move.
Does anyone have suggestions or a list of items to watch out for?
Thank you.
