Seasonal Considerations

Exterior work slows significantly in winter. Best to break ground in spring for full construction season.

Planning Tips

  • Add 15-20% buffer for unexpected delays
  • Material lead times can extend timelines
  • Weather delays are common in PA
  • Permit processing adds to pre-construction
  • Schedule critical inspections early
