<br />This proposal has been prepared in response to a <br />Request for proposal by Mr. Earl Smith, city Engineer, <br />for engineering services required for the development <br />of construction plans and specifications to <br />rehabilitate certain defects presently existing on the <br />Lake Crook Embankment. <br />An on-site inspection was conducted may 1, 1989, <br />by representatives of RSA, Inc, Consulting Engineers, <br />during which various deficiencies and structural <br />defects were noted and photographed. The following <br />descriptions of the various defects, and the <br />recommended improvements to same, are separated into <br />three maj or categories; 1) vegetation removal and <br />sealing of existing rip-rap panel joints, 2) removal <br />and replacement of rip-rap panels, 3) resurfacing and <br />grouting of defective spillway area. <br />VEGETATION REMOVAL AND JOINT SEALING <br />During the inspection of the embankment it was <br />noted that virtually every joint in the existing <br />concrete rip-rap was overgrown with heavy grass and <br />small timber growth which has taken root in the <br />embankment soils beneath the rip-rap panels. In <br />numerous instances the root system of the plants have <br />developed to the point that expansion of the roots have <br />dislodged the panels from adjacent panels and/or caused <br /> <br />GENERAL <br /> <br />I <br />I <br />I <br />I <br />I <br />E <br />. <br />. <br />I <br />I <br />E <br />I <br />I <br />I <br />I <br />IJ <br /> <br />I, <br /> <br />, <br />;;- <br />" <br />:} <br /> <br />,i <br />;!: <br />11: <br /> <br />1! <br /> <br />v~ <br /> <br />: 'r <br /> <br />~ <br />dt <br />" <br />i <br /> <br />i. <br /> <br />1 <br />
