The Longwood Gardens Fountain Revitalization Project is a complete renovation of the existing fountains.  The new design preserves some of the original components and architectural features, while enhancing the fountain design and landscape. The revitalization included 1,400 linear feet of utility tunnels, four below ground pump rooms, and three buried water storage tanks holding 340,000 gallons of water. Many of the key components of the original gardens were preserved and reinstalled, including 379 original nozzles. Worth & Company’s contract included the Fountain Features scope and Mechanical and Plumbing scopes.

Worth & Company worked for over 12 months budgeting the project with the General Contractor without drawings or Specifications.  Once single line schematics of the pumps and piping were issued in 2014, Worth repriced and began extensive Value Engineering efforts in April 2014. Worth & Company received a contract for two bid packages on the project in December 2014, the Fountain Features scope and Mechanical and Plumbing scope.

The Fountain Feature scope:

  • Installation of over 1,700 fountain nozzles and associated piping
  • Installation of air piping to fountain nozzles
  • Installation of ninety (90) fountain display pumps
  • Installation of the fountain tank filtration systems
  • Installation of the water treatment piping
  • Installation of the leaf catcher (band screen)
  • Installation of the complete fountain pneumatics system
  • Provided support during the start-up and commissioning phase

The Mechanical and Plumbing scope:

  • Installation of a geothermal well field and associated piping
  • Installation of energy recovery unit, water source heat pump, Fans, unit heaters and dehumidifiers
  • Installation of domestic hot and cold water systems along with the sanitary system
  • Installation of a propane gas system complete with leak detection

Worth & Company was vital to the successful completion of the Longwood Gardens Fountain Revitalization.  From extensive preconstruction activities and value engineering to MEP coordination, schedule coordination, to change management, Worth & Company confidently ensured that all obstacles were overcome, and the Owner was able to open this amazing facility on schedule.

During the preconstruction phase, Worth's in-house capabilities were invaluable in creating and coordinating a 3D model of your fountain, mechanical and plumbing systems, intertwined with the electrical, audio/visual, IT, fire protection, life safety and fountain controls equipment. Worth's capabilities to prefabricate much of the installation and fabricate many of the custom stainless steel fountain components helped maintain schedule and provide a cost-effective approach. Worth was able to exceed expectations and provide superior construction quality and longevity.
