Item 5HCity of Southlake, Texas M E M O R A N D U M To: Shana Yelverton, City Manager From: Charlie Thomas, P.E., Public Works Director Subject: Award bid for the S.H 114 at Dove Road Water Line Reconstruction and Continental Blvd. Water Line Reconstruction to North Texas Contracting, Inc. Action Requested: Award bid for the S.H 114 at Dove Road Water Line Reconstruction and Continental Blvd. Water Line Reconstruction to North Texas Contracting, Inc. Background Information: Last year a significant waterline leak was discovered at Dove Street and SH 114.After thorough investigation has been determined that the existing 18” (inch) waterline at S.H. 114 and Dove failed at a location deep inside a casing under S.H. 114 making repair impracticable. Replacement will consist of slipping a 12” (inch) waterline inside the existing 18” (inch) waterline. The reduction in capacity will not have significant system impacts. In October of last year, a water line break was discovered on Continental Blvd. The existing 12” (inch) waterline on Continental Blvd. failed at a 45 degree bend underneath an existing box culvert, just east of Ridgewood Circle, making repair of the line impracticable. Replacement will consist of 600 LF of a new, more flexible 12” (inch) waterline that will be bored parallel to the existing line eliminating the need for 45 degree bends underneath the box culvert. th Three bids were received on January 10, 2006.
