No, it’s because of everything. Increased specialization of our construction crews, increased oversight and regulation, increased labor costs due to improved working conditions, improved safety requirements reducing productivity, increased shipping and manufacturing time for increasingly specialized tools and building materials, reduced working hours to cause less impact to traffic and noise, increased sync points to inspect the work and ensure it’s good before moving to the next step, mechanization reducing the number of people that can work at one time because the equipment is large and expensive, increased project complexity because complex materials and construction practices are more efficient in specific ways, etc.
