2010/12/08 Council Agenda Packet

2 i. Spot elevations on hard surfaces on a separate layer. ii. Display and identify all physical improvements, including traffic control and lane striping that is visible on the surface within survey limits. iii. Show invert elevations, ID dimensions and pipe material (if discernable) of storm drain pipes, sanitary sewers, catch basins and manholes. iv. Depict contour lines at 2-foot intervals or better. v. Control points with elevations and point numbers. c. Monument Records: i. Prepare Destruction Permits for two "Broadway"monuments and submit to DNR. ii. Prepare and file Monument Records with City of Everett detailing positions of monuments existing and surveyed during the course of the project. Deliverables: • AutoCAD Electronic file of engineering Basemap using City of Everett CADD standard • ASCII Point file containing: Point#,Northing, Easting, Elevation and Description. • Land XML and Civil 3D files • Two DNR Permits to Destroy monuments. • Electronic file of the 1" -=20", 2 foot contour interval or better,basemap of the site with calculated boundary. TASK 3: GEOTECHNICAL ENGINEERING: Geotechnical engineering support will be performed by TranTech's subconsultant HWA. The objective of this will be to evaluate soil and ground water conditions that impact the design and construction of the new bridge structure. The geotechnical engineering effort will include the following activities: A. Project Management HWA will manage the geotechnical engineering work and the work of its subcontractors. HWA will correspond with the TranTech team by email and telephone as required to complete its work scope and support the team. HWA will provide monthly progress reports if requested,with each monthly invoice. B. Review Existing Geotechnical and Geo-Environmental Information HWA will collect and review existing geotechnical data in the project area. This will include available boring logs, geologic maps, and foundation plans for nearby structures. HWA will review files with the City of Everett, BNSF, available online databases, and HWA's geotechnical library. The information collected will then be considered in development of the geotechnical engineering investigation. HWA will also collect and evaluate available site characterization data within and adjacent to the bridge alignment. This includes a database report of federal, state, and local regulatory agency databases and information on chemical and hazardous wastes which may have been stored or generated in the site vicinity. More specifically, this records search will focus on 17
