1. APPLICABLE CODES INCLUDE THE 2021 VERSIONS OF THE IBC, IMC, IECC, IPC, IFGC AND THE 2023 VERSION OF THE NEC.

GENERAL CONSTRUCTION NOTES:

1. THE SCOPE OF WORK FOR THIS PROJECT WILL INVOLVE UPGRADE OF THE EXISTING BOILER PLANT.

2. DEMOLITION INCLUDES THE REMOVAL OF EQUIPMENT/PIPING AS NOTED ON THE PLANS AND PATCHING/REPAIRING WALLS WHERE PIPING IS

REMOVED.

3. COORDINATE STAGING AREA FOR CONSTRUCTION WITH THE OWNER.

4. THE CONTRACTOR WILL BE RESPONSIBLE FOR ALL WASTE DISPOSAL FOR THIS PROJECT. COORDINATE THE LOCATION OF WASTE DUMPSTERS

WITH THE OWNER.

5. THE CONTRACTOR IS TO VERIFY ALL DIMENSIONS AND ACCESS REQUIREMENTS FOR ALL NEW EQUIPMENT PRIOR TO ORDERING MATERIAL.

6. ANY WORK THAT DISTURBS OR ALTERS THE ROOF AND ROOFING MATERIAL IS TO BE RETURNED TO PRE-CONSTRUCTION CONDITIONS AND THE

ROOF MADE WEATHERTIGHT.

SCOPE OF NEW WORK / PROJECT BIDDING:

THE PROJECT WILL BE BID PER THE FOLLOWING SCOPE OF WORK:

1. REPLACE THE EXISTING 550 MBH BURNHAM ATMOSPHERIC BOILER WITH A NEW 500 MBH LOCHINVAR KNIGHT XL (OR APPROVED EQUAL)

HIGH-EFFICIENCY, SEALED COMBUSTION UNIT.

2. REPLACE THE EXISTING AIR SEPARATOR, EXPANSION TANK, AND HEATING WATER PUMPS WITH NEW.

3. MODIFY THE EXISTING BOILER PIPING ARRANGEMENT TO BE A PRIMARY / SECONDARY SYSTEM.

4. THE EXISTING COMBUSTION AIR DUCT SHALL BE REMOVED AND THE NEW BOILER 4" INTAKE AND VENT SHALL BE ROUTED THROUGH THE EXISTING

LOUVER.

5. NEW DISTECH CONTROLS SHALL BE PROVIDED FOR THE BOILER AND PUMPS BY MSI OUT OF ENGLEWOOD, CO AS AN ADD ALTERNATE.

6. VERIFY THE EXISTING HEATING WATER SYSTEM HAS 30% PROPYLENE GLYCOL. PROVIDE ADDITIONAL GLYCOL AS REQUIRED TO REACH 30%.

7. EQUIPMENT TO BE COMMISSIONED IN ACCORDANCE WITH THE IECC SECTION 408.

ADD ALTERNATE:
