The designed storm drainage catch basins could not be installed due to conflicts with the MSE wall's anchorage system on the EA-line on the western approach to the bridge from STA 14+00 to STA 18+30. Five Type I CBs were deleted and six curb inlets were added to avoid the conflicts with the anchorage system. Cost $4,680.00 5. Per the COE and PUD Limited Use Permit Agreement, the contractor was required to install additional drainage and gates between the PUD substation and COE's Right-of-Way. The Contractor had begun the installation of the bridge soffit falsework when PUD directed them, on August 28, 2002, to remove the falsework and to stop work on the PUD easement until the Limited Use Permit Agreement was signed by the COE. The PUD also required an additional 7-foot temporary construction fence to be installed on the soffit work platform until the permanent fence was installed. Cost $9,742.31 6. The City of Everett and the Port of Everett requested the up-sizing of the storm drainage pipe from 6-inch to 8-inch ductile iron pipe on Federal Avenue. Cost $6,021.12 7. During the installation of the new construction of the water main and storm sewer revisions, numerous conflicts arose due to unmarked or mismarked utilities and design elevation /field elevation differences. a. During installation of the storm sewer from Curb Inlet#12 to Catch Basin #5, the newly installed, redesigned water main was found to be at the same elevation. A portion of the water main was removed in order to install the gravity flow drainage system and then reinstalled to avoid the conflict with the storm sewer. b. The contract drawings indicate the raising of the sewer manholes to be completed by installing a precast riser. The existing manholes were not precast, but tongue and groove manholes. The City of Everett directed the Contractor to install the precast risers with a Type 4000W concrete collar. c. Redesigned water line to avoid conflict with storm drainage line from CB#1 to CB#2 and existing 24-inch wood stave concrete encased pipe. d.
