Surveys and Utility Location. Provide, through a subcontract, field run topographic surveys of the Pump Station #8 site, construction office area, connection structures and pipe alignment. It is assumed the Pump Station #8 site and construction office area will be less than two acres. Survey limits along the pipeline are assumed to include a 7,000 feet long by 100 feet wide area (50 feet from centerline on each side of the alignment). Field surveys will include all planimetric features, breaklines, and sufficient ground data to compile accurate mapping at a scale of 1”= 20’ with 1 foot contours. Field run surveys will include all surface features of underground utilities, including pipe sizes, material and invert elevations for all gravity sewer and drainage systems. Up to ten (10) utility locates requiring vacuum excavation may be performed on the project. Surveyor is to coordinate with the Geotechnical Engineer for this project. Survey coordinate locations and vertical control at each boring site prior to drilling to ensure borings are being drilled within ROW or City owned easements. Boring elevations will be surveyed following installation for vertical control.
