It is <br />understood that the purpose of this field investi~ation <br />program is to obtain site specific geotechnical data for the <br />Hardin Dam site and that such data is not available from <br />previous studies and investigations. <br /> <br />It is agreed that both Exhibit B (Scope of Services) to <br />the Contract of January 18, 1982, between the Colorado Water <br />Conservation Board and Dames & Moore, as well as, the Plan <br />of Study for the Hardin Dam project shall be revised by <br />mutual consent as follows: <br /> <br />( 1 ) The following paragraph shall be added to Task 4 <br />of the Scope of Services as Section 4g. and shall also be <br />added to Section 2.4 of the Plan of Study as an inclusion to <br />the listed items under the first paragraph: <br /> <br />A limited drilling and borrow material field <br />program will be performed to generate site specific <br />geotechnical data. This information is not available <br />from the data base. The site specific data will be the <br />key ingredient in performing an independent design and <br />development of an associated cost estimate for Hardin <br />Dam. The drilling program will include seven borings, <br />borrow material investigation, laboratory testing and <br />associated data reduction and report prepar~tion. <br /> <br />Green/uk: 523 <br /> <br />.~ <br /> <br />'1 <br /> <br />_. ^' J-.
