23-PW-092 - CMP Lining Project

The City of Arvada Public Works Department is looking for a qualified Contracting firm for services related to the sinkhole issue, and the replacement of a new access hole ((a.k.a. manhole) at any change in horizontal or vertical alignment.
In July of this year, a sinkhole developed south of W. 60th Avenue just west of Newland Street in the City of Arvada, Colorado. As of issuance of this solicitation request, the sinkhole is approximately 6-feet in diameter and approximately 12-feet deep and is near a residential retaining wall.  Currently there is a bend in the CMP which does not conform to the City’s Standards and Specifications.
