GENERAL DEMOLITION NOTES:

1. PROPOSED PHASING NOTED ON DESIGN DRAWINGS IS PRESENTED AS ONE POSSIBLE

OPTION, AND IS AN EXAMPLE ONLY. ANOTHER POSSIBLE OPTION IS TO INSTALL A

TEMPORARY BOILER DURING THE PROJECT TO ALLOW REPLACEMENT OF BOTH

BOILERS AT THE SAME TIME. CONTRACTOR RESPONSIBLE FOR INSTALLATION

SCHEDULE TO MINIMIZE SYSTEM DOWNTIME TO ONE DAY MAXIMUM AT A TIME.

DOWNTIME MAY BE REQUIRED TO BE LIMITED TO WEEKENDS BY OWNER.

CONTRACTOR TO SUBMIT FULL PROJECT SCHEDULE WITH RECOMMENDATIONS ON

PHASING.

2. HAZARDOUS MATERIALS ABATEMENT IS AN INTEGRAL PART OF THIS PROJECT, AND

MUST OCCUR/START PRIOR TO PHASE 1 WORK. SEE DIVISION 00 AND 02

SPECIFICATIONS, INCLUDING REPORT FROM FUSS & O'NEILL, FOR ADDITONAL

INFORMATION AND REQUIREMENTS REGARDING ABATEMENT OF OF CEILING, BOILERS,

AND FLUE. CONTRACTOR TO SUBMIT FULL PROJECT SCHEDULE WITH

RECOMMENDATIONS ON PHASING, INCLUDING ABATEMENT PHASING. PHASING MUST

INCLUDE TIME REQUIRED TO OBTAIN VARIANCE FROM STATE TO ALLOW ABATEMENT

WHILE SCHOOL IS OCCUPIED WITH STUDENTS.

3. CONTRACTOR MAY NEED TO TEMPORARILY CONNECT EXISTING EXPANSION TANKS TO

NEW HOT WATER SYSTEM, DEPENDING ON SCHEDULE OF PLUMBING CONTRACTOR

AND REMOVAL OF SECOND DOMESTIC HOT WATER STORAGE TANK LOCATED WHERE

NEW EXPANSION TANKS WILL BE INSTALLED. CONTRACTOR TO INCLUDE ALL

TEMPORARY CONNECTIONS IN BID PRICE.

4. BOILER PLANT SHALL REMAIN OPERATIONAL FOR ENTIRE DURATION OF PROJECT.

CONTRACTOR SHALL COORDINATE SHORT TERM SYSTEM SHUT-DOWNS WITH OWNER

IN ADVANCE.

OF CEILING, BOILERS, AND FLUE. CONTRACTOR TO SUBMIT FULL PROJECT SCHEDULE WITH RECOMMENDATIONS ON PHASING, INCLUDING ABATEMENT

PHASING. PHASING MUST INCLUDE TIME REQUIRED TO OBTAIN VARIANCE FROM STATE TO ALLOW ABATEMENT WHILE SCHOOL IS OCCUPIED WITH

STUDENTS.

3. BOILER PLANT AND DOMESTIC HOT WATER HEATERS SHALL REMAIN OPERATIONAL FOR ENTIRE DURATION OF PROJECT. CONTRACTOR SHALL

COORDINATE SHORT TERM SYSTEM SHUT-DOWNS WITH OWNER IN ADVANCE.

4. ALL NEW EQUIPMENT (BOILERS, PUMPS, DOMESTIC HOT WATER HEATERS, DOMESTIC HOT WATER RECIRCULATION PUMPS, DOMESTIC HOT WATER

MIXING VALVES, ETC.) SHALL BE CONNECTED TO THE ALERTON BUILDING DDC SYSTEM BY AUTOMATED BUILDING SYSTEMS, INC. (ALERTON). PROVIDE
