Jansen Inc. 1/16/2021 Change Order 4

Project: Everett Downtown Streetscape Improvement Change Order No.4 Change Order Effective Date: December 9, 2020 JUSTIFICATION: Modified Items: Existing Bid Item # C-9—Flaggers. This bid item overran plan quantity and is being modified to account for costs of additional flaggers hours. The original plan quantity allowed for 2,400 flagging hours on schedule C. Original Contract time allowed for 150 working days. Dividing 150 working days into the 2,400 flagging hours allows for 16 flagging hours per day or roughly 2 flaggers per day. In order to maintain the quality of life for various businesses in the project area, at one point up to 9 flaggers per day were used, 3 flaggers to keep Library Place open, 3 flaggers to keep the Aero Apartments open and 3 flaggers to keep the Full Life Center open to traffic and accessible. Although the duration of the need for 9 flaggers per day was much shorter than 150 days,this demonstrates why flagger hours under this bid item overran. Existing Bid Item #C-26—Cement Concrete Pavement. This bid item overran plan quantity and is being modified to account for additional quantities of Cement Concrete Pavement. The original plan quantity in schedule C was for Cement Concrete Pavement panels west of the radius tangent locations on the western side of California Street and Rucker Avenue intersection. The plan quantity of Cement Concrete Pavement was increased on schedule C of the Contract, because the City of Everett directed the Contractor to open a portion of Rucker Street up to thru traffic to maintain access to Library Place, prior to them being able to place the Cement Concrete Pavement panels in the radius area on the west side of Rucker Ave. Existing Bid Item #D-3—Gravel Borrow Including Haul. This bid item overran plan quantity and is being modified to account for additional quantities of Gravel Borrow Including Haul that resulted from differing site conditions encountered on the project. At various locations along Rucker Avenue excess roadway excavation was completed to remove unsuitable type materials and those areas were backfilled with gravel borrow. Existing Bid Item #D-4—Roadway Excavation Including Haul. This bid item overran plan quantity and is being modified to account for additional quantities of Roadway Excavation Including Haul that resulted from the differing site conditions that were encountered on the project. Existing Bid Item #D-5—Crushed Surfacing Base Course(CSBC).
