9 Impacts and Management 9

10 Listened to concerns about current construction impacts Developed updated technical solutions for foundation construction methods and demolition Documented concerns to support expenditures for new construction methods and security measures Fall 2017 Phase 4 Near Neighbors Meeting 10

11 Goal is to reduce construction impacts to adjacent properties Can reduce but not eliminate noise and vibration through: Demolition methods Pile installation methods near homes Phase 4 Construction Near Aramingo Avenue 11

12 Time restrictions on when demolition can occur To reduce noise, contractor will: Cut bridge barriers and decks and remove by truck Phase 4 Lower beams to the ground and remove by truck Break down larger items off-site Saw cutting and hammering to break up concrete will still need to occur e.g. for pier columns Demolition Process Rendering 12

13 Phase 3 used driven piles, which were hammered into the bedrock, to build structural supports Phase 4 will use micropiles and driven piles Micropiles are drilled then filled with concrete Micropiles reduce, but don t eliminate, noise and vibration Phase 4 will use micropiles near residential areas Micropiles to start in mid-june Phase 4 Micropile Installation in Downtown Seattle Source: WSDOT 13

14 PennDOT and its contractor received complaints about construction vibration, noise, and dirt during Phase 3 The contractor will install vibration monitors at locations along the project area If you have concerns, document property condition with photos and video prior to start of demolition Construction in the Interchange Area 14

15 Security patrol from Monday-Sunday 5:00pm to 7:00am Temporary (interim) understructure lighting during construction Security fencing Increased site watering Clearance of site debris Temporary Fencing Under the Viaduct 15
