AUG-33-4.44 Cofferdam and Dewatering – Proshot Concrete / ODOT – Auglaize County, OH

STONE prepared dewatering and cofferdam working drawings for the construction of lining the existing culvert with a spray-applied structural liner. STONE value-engineered a change from use of a sheet pile wall to use of a non-erodible fill cofferdam to allow for dewatering for construction. STONE also reduced the need for surveying by suggesting use of the existing flood level monitor on the bridge in lieu of providing staking along the bank.

“STONE has provided industrial environmental compliance auditing on several project sites for Amec Foster Wheeler during the last 18 months.  They are very thorough, prompt, and knowledgeable in implementing the work.  Sharon and STONE are focused on customer service, which is refreshing.”
