MSEL heating hot water line installation

As part of the Milton S. Eisenhower Library (MSEL) modernization project, a new 20″ Heating Hot Water (HHW) line to support future work north of the library will be installed. This work will take place in two phases during standard construction hours, from July 1 through October 10.

Phase 1: July 1 – August 14, 2025
Installation of HHW piping along the west side of the loop

• Vehicle access will be maintained via road crossings north and south of the site fence with ramp entries.
• A temporary ADA-compliant blacktop walkways will be installed.
• Traffic barriers, orange fencing, and detour signage will be in place for safety.
• Flaggers and spotters will guide pedestrians and vehicles through and around the work zone.

Phase 2: August 15 – October 10, 2025
Installation of HHW piping through the loop and into the beach area

• ADA detours will shift to the west side of the loop using newly installed blacktop walkways.
• Additional fencing will secure the work zone; signage and flaggers will remain in place.
• Short-term, limited closures of the East Gate Loop roadway may occur during construction hours and will be coordinated with JHU at least two weeks in advance.
• Road plates will be used to maintain vehicle access across open trenches.
• Restoration of the roadway and beach area will follow backfill, including resurfacing and sod installation.

Safety & Accessibility Measures (Both Phases):

• Pedestrian pathways in the area will be closed.
• All detours will be clearly marked and ADA-compliant.
• Flaggers will be stationed at road crossings to manage both pedestrian and vehicular traffic.
• Protective measures such as filter cloth and sand layers will be used to preserve existing hardscape features.
