Ahtna Construction & Primary Products Company, LLC (ACPPC) is working with the U.S. Army Corps of Engineers (USACE), Alaska District, to prevent future erosion of the Chena River Lakes area. The $8.9 million Repair Tanana Sill Groin Chena River Lakes Flood Control Project consists of the placement of class IV riprap onto the existing sill groin slope protection. The existing sill groin consists of smaller riprap and is subjected to extreme weather and severe spring breakup conditions, leading to erosion.
Work is being performed at the Cantwell Panorama Mountain Rock Quarry (approximately MP 217 of the Parks Highway) and Tanana Sill Groin locations. Work at the Cantwell Rock Quarry will consist of riprap production and sorting, vehicle/material scaling, and loading for transport via double-side dump trucks to North Pole. Deliverables include pre-construction documents, Quality Control Plan, Safety Plan, Storm Water Pollution Prevention Plan (SWPPP), material quality/gradation tests, daily reports, schedule updates, etc.
This project is unique since Ahtna, Inc. (Land and Resources Dept.) is providing the riprap material for the project, and an Ahtna subsidiary (ACPPC) is responsible for constructing the project. ACPPC has recently purchased three excavators, twin scales, GPS for one of the excavators, and a hydraulic breaker attachment for this project. In addition to the equipment purchased, ACPPC will utilize existing equipment to support the successful project completion.
This project will require various heavy equipment operators in both the Cantwell Rock Quarry and Tanana Sill Groin locations. ACPPC will be looking for shareholders with experience operating track excavators, wheeled loaders, articulated rock trucks, as well as scale operators and mechanics.
