Question #14, Case 4: HVAC units The general contractor on this project chose not to purchase the heating, ventilation, and air conditioning (HVAC) equipment from the mechanical subcontractor, but rather they purchased it directly from the manufacturer. Why would a GC do this? The shop drawings were submitted and were per specifications. The submittal was approved and returned on time. The equipment was delivered on time, but because the HVAC subcontractor had not yet mobilized on-site, the GC unloaded the mechanical units from the truck and hoisted them to location with the GC's own crane. The subcontractor connected the equipment after placement. The system was completed on schedule, but on a very hot design day, during HVAC balancing, it is discovered that the units are not keeping up with air conditioning requirements. The labels are checked, and it is discovered that they are undersized by one-third from the specified units. The approved submittal does not match up with what has been installed. Who is at fault? How could "active" quality control have prevented this from happening? How is it now and/or should be resolved contractually and physically?

Transcribed Image Text:Question #14, Case 4: HVAC units
The general contractor on this project chose not to purchase the heating,
ventilation, and air conditioning (HVAC) equipment from the mechanical
subcontractor, but rather they purchased it directly from the manufacturer. Why
would a GC do this? The shop drawings were submitted and were per
specifications. The submittal was approved and returned on time. The equipment
was delivered on time, but because the HVAC subcontractor had not yet mobilized
on-site, the GC unloaded the mechanical units from the truck and hoisted them to
location with the GC's own crane. The subcontractor connected the equipment
after placement. The system was completed on schedule, but on a very hot design
day, during HVAC balancing, it is discovered that the units are not keeping up
with air conditioning requirements. The labels are checked, and it is discovered
that they are undersized by one-third from the specified units. The approved
submittal does not match up with what has been installed. Who is at fault? How
could "active" quality control have prevented this from happening? How is it now
and/or should be resolved contractually and physically?
