When contract pipe liner installation is proposed, consideration should be given to allowing optional replacement in the bidding documents if the project location, traffic impacts and staging can facilitate the replacement option.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Pavement and shoulder cross slope requirements should be met, but opportunities still may exist to use the coldmilling in reducing overall impacts.  Coldmilling costs are often offset or negated by the material salvage value if the coldmilling is approximately 1” or greater.  &lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
