MOOSE CREEK DAM SAFETY MODIFICATION INDUSTRY DAY / SITE VISIT NOTICE -- AUGUST 2020

INTRODUCTION

Chena River Lakes Flood Control Project

The Moose Creek Dam Safety Modification project is for construction of a mix-in-place barrier wall in the embankment of Moose Creek Dam at the Chena River Lakes Flood Control Project. This will consist of constructing 4.5 miles of barrier wall 56 to 66.5 feet below the crest of the dam embankment with Portland Cement and Bentonite. The barrier wall is expected to be between 24 and 30 inches wide and have an unconfined compressive strength of 200 psi at 28 days and approach 500 psi in the long term. Sheet pile will be driven around the low point drain and control works to have a continuous wall through penetrations in the embankment. The intent of the barrier wall is to sever a continuous fine grained sand / silty sand that is highly erodible under the embankment material. Mix in place methods shall be utilized to mix the embankment and foundation materials with Bentonite and Portland Cement in order to construct a Barrier Wall through Moose Creek Dam. Any methods that utilize a bentonite slurry trench to support the embankment while excavation of the barrier wall takes place will NOT be utilized at Moose Creek Dam. The potential loss of slurry could result in failure of the embankment into the excavation during construction due to highly pervious foundation materials.

The NAICS Code for this requirement is 237990, Other Heavy and Civil Engineering Construction. The disclosure of magnitude for this project is between $100,000,000.00 and $250,000,000.00.
