In this case study, there is only 2 weeks left to turnover the building and a lot of the inspections have been completed and passed. As the work was being done they realize that the subcontractor has been installing different sprinkler heads on every floor for the three floors of the building. Since there is only two weeks left till completion, the two options I came up with is either they convince the owner that the sprinkler heads are up to code and will get the job done even though it is not the ones that were initially picked. The other option is that the Contractor and sub contractor comes together to figure out who is going to redo all the sprinkler heads, which will take more time and money to complete. This error falls on the GC because its the general contractors job to make sure the job is running smooth and correctly. If the GC hires a sub contractor to do the job, it is his/her responsibility to check on the subs work. So the owner should not have to pay for any changes if the work was clarified in the drawings.
