We had a meeting today with the Archdiocese and the contractors and it went very well. We will be beginning construction on Monday, September 15, and it is expected to last no more than two months (though with construction, of course, anything can happen!) During the time of construction the main church will be closed and we will have all Masses in the day chapel, with chairs in the narthex as necessary for the weekend Masses. It will be cozy for some of the more heavily attended Masses, but it is much better than the scheduling difficulty that having Mass in the Social Hall would produce.
A few weeks of disruption will be well worth it once it is all over!
