So far as I know, Bechtel engineers/senior managers are housed in a block of flats - sorry, no idea where.  They used to be in a building near my own but left because of lack of maintenance issues with the property manager - the building was OK, the upkeep (getting appliances repaired, lights fixed, lack of proper security, etc) was the reason I was told they left when the contract expired.

I have known people who worked for Bechtel in other countries, they do try to take good care of their people - and a good standard of housing is usually the norm
