City of Arden Hills May 3, 2019 Page 2 B. Scope of Basic Services Based on our understanding of the project we proposed the following scope of services: 1. Site Access Based on a review of on-line aerial photos it appears that the roadways and parking lots can be accessed with our CME-55 truck mounted auger drill. We assume that traffic volumes on these residential streets are low and no special traffic control e.g. flagmen is necessary. We will utilize our drilling support truck, flashing lights and cones to allow traffic to self-regulate around our crew. 2. Bore Hole Locating and Gopher State One Call We will stake the proposed bore hole locations using a supplied site plan and existing site features as guides. Elevations at the bore hole locations will not be determined. However, if requested we can provide a survey crew to tie-in our as-drilled boring locations for an additional fee. Also, the city may provide a surve y crew to survey and elevate the as-drilled boring locations. Prior to sending a drill rig to the site WSB will contact Gopher State One Call (GSOC) and have them request public underground utility owners mark and clear our proposed bore hole locations of their utilities. If there are private underground utilities that are not located by GSOC, you must notify WSB immediately. WSB will take reasonable precautions to avoid underground facilities. 3. Subsurface Test Borings Based on the RFP, the City has requested 27 soil borings to a depth of 10 feet each on the existing alignments and parking lots. We propose to complete standard penetration test borings. In the standard penetration test borings, we will sample and record blow counts at 2 ½ foot intervals to the boreholes termination depth. If unsuitable soils (soft soils, organic soils, etc…) are encountered at the proposed boring termination depth(s), it will be necessary to extend the borings into more competent materials. This will allow us to better evaluate potential construction issues. An additional charge of $20 per lineal foot will be assessed for borings extended beyond their proposed termination depths. If the added work requires an additional mobilization to the site it will be charged at $500 per day. In Minnesota, a boring that is deeper than 15 feet is considered an environmental well and requires Well Sealing Notification and Sealing Records be submitted to the Minnesota Department of Health, along with a Notification fee. The borings are planned to depths of less than 15 feet, but if they are extended due to the presence of unsuitable soils at planned termination, than additional fees will be incurred. WSB will fill out the MDH notification and sealing record forms and sign on behalf of the owner u nless directed otherwise.
