Value Delivered

When a significant steam explosion occurred at 5:30 a.m. on a Sunday morning in August, a team of experts from Tucker Mechanical, Inc. quickly mobilized to provide temporary service and engineer a solution.

The explosion disrupted hot potable water, heating hot water, and chilled water service to 16 facilities including Connecticut State Office buildings and two private residential high-rise towers.

We were able to quickly secure a severely-damaged utility plant, and coordinate subcontractors, material deliveries, and project personnel. Working around the clock, we restored chilled water service within 3 days.

We also worked 12-hour days, 6 days a week, to restore heating hot water service
three days ahead of the mid-October deadline.

Client Objectives

The client needed to restore multiple water services to 16 buildings and needed expert mechanical and fabrication solutions.


We restored chilled water service using two temporary 3,000-gallon-per-minute diesel pumps located and piped outside the plant’s damaged perimeter.

Because the heating hot water needed both boilers and pumps for temporary service, our CAD experts collaborated with engineers from BVH to provide equipment and piping layouts for State approval.

Once approved, our fabrication team in our 40,000-square-foot shop custom-made spool pieces to assemble 20-inch carbon steel hot water supply and return lines for:

  • Two temporary 650-horsepower boilers
  • Two 150-horsepower circulating pumps

To ensure all the new equipment was operating successfully, we also provided a boiler supervision team on site 24/7 for two weeks.
