SCOPE OF WORK

THE EXISTING 18-INCH BLACK STEEL UNDERGROUND CHILLED WATER PIPING WILL BE

REPLACED WITH 18-INCH UNDERGROUND HDPE CHILLED WATER PIPING IN SAME LOCATION.

BASE PLAN INCLUDES THE PIPING BEGINNING AT THE NEW VAULT AND EXTENDING TO THE

UNDERSIDE OF THE BUILDING ENTRANCE. BLACK STEEL WILL CONNECT AT THE BUIILDING

ENTRANCE WHERE THE 18-INCH CHILLED WATER SUPPLY AND RETURN RISERS WILL HAVE

18-INCH BUTTERFLY VALVES ADDED FOR THE BUILDING ISOLATION. ALTERNATE 1 WILL

INCLUDE ADDITIONAL DISTANCE FOR THE CHILLED WATER REPLACEMENT SCOPE OF WORK.

THIS WORK INCLUDES THE UNDERGROUND PIPING FROM THE EXISTING VAULT 5 TO THE

NEW VAULT.

THE NEW VAULT WILL HOUSE TWO 18-INCH ISOLATION VALVES TO SERVE THE FUTURE

COURT HOUSE EXPANSION.

THE COURTHOUSE BUILDING WILL REQUIRE TEMPORARY COOLING FOR THE DURATION OF

THE CHILLED WATER REPLACEMENT PROJECT. THE BUILDING WILL REQUIRE STAGING

WORK FOR THE CONNECTION TO THE TEMPORARY CHILLER. WORK INCLUDES SETTING UP

CHILLED WATER PIPING CONNECTIONS FOR A TEMPORARY CHILLER. INSTALLATION OF

VALVES WILL REQUIRE CRYOGENIC FREEZING OF EXISTING CHILLED WATER LINES FOR THE

INSTALLATION OF VALVES FOR BOTH THE RISERS AND ALSO THE TEMPORARY PIPING

CONNECTIONS TO THE TEMPORARY CHILLER EXPANSION.

CONTRACTOR TO PROVIDE 500 TON AIR COOLED CHILLER WITH GENERATOR FOR

TEMPORARY SERVICE DURING CONSTRUCTION.
