Integration of new piping while maintaining system operations, calls for careful planning

J.F. White successfully cross-connected two chilled water systems located in each of the 42-story Boston Harbor Towers. This project consisted of three phases: the pre-planning, the installation of the underground piping and the upgrade to the chilled water system. Because the job was scheduled during the height of the cooling season, J.F. White needed to create a plan that would maximize productivity and minimize the impact the construction could have on Boston Harbor Tower tenants, vehicle and pedestrian traffic.

After the planning phase was complete, J. F. White installed two below-grade 8-inch lines across the main access to the complex. The exterior below-grade lines consisted of a pre-manufactured, double-wall pipe system that tied the two chilled water systems together. During this phase, J.F. White excavated the area, assembled the pipe and tested the pipe tie-in connection before backfilling the area. Once the chiller plants were interconnected, J.F. White completed phase three -- the upgrade of the chiller plants.

J.F. White completed the chilled water cross-connection system with little interruption to the existing cooling systems. This success can be attributed to the high level of pre-planning, coordination and the quality workmanship that J.F. White exhibited.
