....meanwhile (getting back on topic)
Perhaps the leadership is 'suddenly' realizing that using volunteer contractors and laborers poses real problems with a job of this magnitude. Without the pressure to meet deadline (in lieu of payment for services rendered), the contruction of the new universal headquarters of Jehovah's Witnesses may get completed years later than a typical construction project.
If you've worked on a WT build or remodel, you know that lack of leadership, skilled know-how, scheduling delays, failed supply lines, material waste and general confusion within the labor staff during the whole process is common.
If they begin to do the math, it doesn't take a genius to figure out that building materials increase in cost every year. I'd say the projected budget has hit the ceiling and the accountants are beginning to sweat.
