Items – The NDDOT Main Avenue reconstruction project was adjacent to the <br />Diversion Authority’s WP‐42E project, and the Contract Work Limit between the two projects was <br />established as the north side of removable closure 1 on 2nd St. So. Subsequently, NDDOT decided they <br />would not work or install pavement within 20‐feet of removable closure 1 due to risk concerns, and the <br />20‐feet of 2nd St. So. paving and curb & gutter work became the responsibility of the Diversion Authority <br />and its WP‐42E Contractor. Because of the size and location of the work, paving equipment could not be <br />used. The Engineer and Contractor negotiated the cost of the work. The following are work changes to <br />furnish and install the 20‐feet of paving and curb & gutter north of removable closure 1: <br />a.Forty (40) lineal feet (LF) of curb & gutter, 20 LF on each side of the road, were required. <br />i.The Contractor provided a price of $87.29 per LF to furnish and install the curb & gutter. <br />ii.The Engineer reviewed this proposal and found it to be acceptable. <br />iii.This change adds Contract Unit Price item #195 F&I Curb & Gutter Standard (Type II) CO‐4 <br />for $87.29 per LF multiplied by 40 LF, for a Contract Price increase of $3,491.60.
