This is a set of engineering drawings for a stormwater manhole repair project at Marine Corps Air Station (MCAS) Cherry Point, North Carolina, specifically behind Building 1665. The drawings include a cover sheet with location/vicinity maps, general notes, existing site conditions, new work plan, and construction details.

The project involves repairing an 11'7" x 5'6" concrete flush joint stormwater vault. Key work elements include excavating below grade around the existing manhole, removing and disposing of the existing manhole frame and cover, installing a new manhole frame and flush mount cover, and concrete slab replacement with new dowels. The drawings provide detailed specifications for the manhole frame and cover installation, concrete work, and joint sealing requirements. The site is located along a striped travel way near Building 1665, and the contractor must maintain jersey barriers to contain work areas during construction. The drawings include precise measurements, cross-sections, and step-by-step repair sequences for the concrete and manhole work.
