About this file

This document is an electrical schedule and notes sheet detailing mechanical equipment connections for what appears to be a chiller replacement project. The document includes a mechanical equipment connection schedule listing both existing and new equipment specifications, including chillers, cooling pumps, heat circulation pumps, and small pumps, along with their respective voltage requirements, phases, and load specifications. The scope of work involves the demolition of existing chillers and selected pumps, including the removal of associated electrical components such as conduit, conductors, junction boxes, and supports.

The technical specifications require the electrical contractor to follow current National Electrical Code requirements for conduit fill, verify voltage drops, and confirm all dimensions prior to work commencement. Notable requirements include independent mounting of heavy-duty disconnects from mechanical units, coordination with mechanical drawings for equipment connections, and specific requirements for fire/smoke dampers and duct detectors. The document also specifies that addressable detectors with integral contacts will be provided by Division 28, installed by Division 23, with power wiring by Division 26 and control wiring by Division 28. All electrical installations must comply with NFPA 72 standards and receive architectural approval for device locations.

DEMOLITION SCOPE OF WORK:

SCOPE: THE SCOPE OF WORK INCLUDES THE REMOVAL OF

THE EXISTING CHILLER AND SELECTED PUMPS. THE WORK

WILL INCLUDE BUT NOT BE LIMITED TO DEMOLITION (SEE

BELOW) OF THE POWER, AND MECHANICAL EQUIPMENT

INCLUDING BUT NOT BE LIMITED TO CONDUIT, CONDUCTORS,

JUNCTION BOXES AND SUPPORTS. THE DEMOLITION OF

MECHANICAL EQUIPMENT WILL BE BY OTHERS, THE

ELECTRICAL CONTRACTOR WILL DISCONNECT THE

EQUIPMENT PRIOR TO REMOVAL.

DEMOLITION: ELECTRICAL DRAWINGS ARE DIAGRAMMATIC,

DEMOLITION INFORMATION HAS BEEN LISTED ON THE

CONSTRUCTION DRAWINGS, IN THE SPECIFICATIONS OR

INDICATED BELOW. ELECTRICAL DEVICES AND EQUIPMENT

ARE FROM PICTURES, EXISTING RECORD DRAWINGS AND / OR

SITE OBSERVATIONS. THEIR ACCURACY IS NOT GUARANTEED.

IT SHALL BE THE ELECTRICAL CONTRACTORS RESPONSIBILITY

TO VISIT THE SITE PRIOR TO BID AND VERIFY ALL EXISTING

CONDITIONS AND INCLUDE ALL LABOR AND MATERIAL

REQUIRED FOR THE WORK INDICATED IN THE CONSTRUCTION

SET.

THE PURPOSE OF THE DEMOLITION INFORMATION IS TO

OUTLINE A GENERAL DIRECTION OF WHAT NEEDS TO BE

REMOVED TO ACCOMPLISH THE RENOVATION WORK. THE

WORK IS DIAGRAMMATIC IN NATURE AND IS NOT INTENDED TO

BE ALL INCLUSIVE. THE CONTRACTOR IS RESPONSIBLE TO

VERIFY EXISTING CONDITIONS AT THE SITE AND INCLUDE ALL
