CertainTeed – Asphalt Unloading Station

Share Project:

Corval Group was prime contractor for CertainTeed’s new asphalt unloading and processing expansion. The purpose of the project was to install mechanical systems to allow for asphalt to be unloaded from rail cars or trucks, processed and stored at the existing facility. Up to 1 million gallons of asphalt can be stored until it is ready to be moved into the existing facility and used for roof shingle production. The scope of work included installation of piping, pumps, specialties, and structural steel. Also included were several critical lifts for tanks and equipment. Shop fabrication capabilities were utilized to perform over half of the required welds offsite in Corval fabrication facilities. The main challenge of the project was to maintain the schedule through tough winter conditions as over 95% of work performed was outside.

Construction Facts:
• 30,000 Man Hours Self-Performed
• Project Completed on Time for Start-up
