please answer the question with a 150 word minimum response in terms of construction ethics regarding the above case study.

The project I'm managing has not been going well. CASE STUDY NO. 6 There was, first, an old but working "sewer" where none was supposed to be. It was probably for water drainage, buried when a swamp was filled in to make dry land for faring or settlement purposes a hundred years ago. By the time we had repaired the sewer and relocated the building's site, we had lost two weeks. Now the trenchers have unearthed 19th Century gravestones, six so far, it suggests that the site might be a forgotten graveyard. If it is a graveyard, we have to stop all work until the graves are moved. Opening a grave without legal authority is a crime. When I phoned my boss with the bad news, he just said "Don't worry. Did you ever hear of a graveyard in a swamp? The gravestones are probably just part of the fill. Ignore them. Don't tell anybody. We can't afford to lose any more time." My boss is right, of course. We can't afford to spend a week or two waiting for someone from the county to make up his mind about whether the gravestones are just debris, or, instead, mark a buried graveyard. On the other hand, though, I'm the one in charge of the job. If this is a graveyard, and I don't notify the authorities, I'm the one who will be responsible for the desecration 2.
