Lock and Dam 3 and 7 Guidewall Repair

AMS has been awarded the Lock & Dam 3 and Lock & Dam 7 Guidewall Crib Repair project with USACE in Minnesota. We will repair the guidewall cribbing and fill void areas through the underwater installation of formwork and the pouring of cellular concrete. This work will serve to fortify the existing guidewall structures and ensure continued functionality.
