Looking at the schedule from the general contractor, three primary times fit most of our volunteers:
May 1-June 15: Framing of wood and steel components
July 15-August 5: Exterior siding
August 17-September 21: Sheetrock
As you plan, consider primarily these three timeframes. However, some of you have special skills in concrete, trim, cabinetry, and other specific aspects of construction. So, consult the construction schedule sent in a previous email to see what the timeframe might be for those aspects.
