HOUR 1. CONTRACT DRAWINGS AND SPECIFICATIONS ARE COMPLEMENTARY AND MUST BE USED IN CONJUNCTION TO OBTAIN COMPLETE

CONSTRUCTION INFORMATION. CONTRACTOR SHALL COORDINATE ALL DRAWINGS AND SPECIFICATIONS PRIOR TO COMMENCING WORK.

QUESTIONS REGARDING DESIGN INTENT OR SYSTEM OPERATION SHALL BE PROMPTLY BROUGHT TO ATTENTION OF THE COR.

2. INSTALL DEVICES AND SYSTEM WIRING TO AVOID DISTURBANCE TO HISTORIC FABRIC AND TO AVOID VISUAL INTRUSION INTO PUBLIC VISITATION AREAS. HISTORIC PRESERVATION SHALL BE TAKEN INTO ACCOUNT THROUGHOUT THE PROJECT.

3. USE EXISTING ROUTING FOR NEW FEEDERS AND BRANCH CIRCUITS WHENEVER POSSIBLE. IF A PATH IS FOUND TO BE UNTENABLE, CONFIRM NEW ROUTING WITH THE COR. WIRING SHALL BE INSTALLED WITHIN CONDUIT WHERE EXISTING PATHS INCLUDE CONDUIT.

4. USE EXISTING HOLES AND OPENINGS TO INSTALL CONDUIT AND CABLE. WHERE NO USABLE PATH EXISTS, CUT NEW HOLES. COORDINATE

SIZE AND LOCATIONS OF DRILLED HOLES AND CUT OPENINGS WITH THE COR.

5. CONTRACTOR SHALL VISIT SITE AND BECOME FAMILIAR WITH THE SITE PRIOR TO SUBMITTING BID.

6. THE TERM "REMOVE" MEANS DISCONNECT AND REMOVE THE DEVICE INCLUDING OUTLETS, BRANCH CIRCUIT WIRING AND RACEWAY.

7. THE TERM “PROVIDE” MEANS FURNISH AND INSTALL, COMPLETE AND READY FOR USE.

8. THE TERM “CONTRACT DOCUMENTS” MEANS THE PROJECT MANUAL, DRAWINGS, ADDENDA, SKETCHES AND OTHER DOCUMENTATION THAT

DEFINE THE WORK.

9. ANY CONFLICTS BETWEEN SPECIFICATIONS AND DRAWINGS SHALL BE PROMPTLY BROUGHT TO COR’S ATTENTION. THE CONTRACTOR SHALL NOT PROCEED WITH ANY WORK EXCEPT AT THEIR OWN RISK, UNTIL CLARIFICATIONS OF CONFLICTS ARE ISSUED TO THE

CONTRACTORS BY THE COR.

10. WHERE DEVICES, WIRING, MOLDING, ETC. ARE TO BE REMOVED FROM EXISTING HISTORIC FABRIC AND REMOVAL MAY NOT BE POSSIBLE WITHOUT DAMAGING EXISTING HISTORIC FABRIC, NOTIFY COR PRIOR TO THE REMOVAL OF THE ITEM.

11. PROVIDE ENGRAVED, PHENOLIC NAMEPLATE PANELS, SAFETY SWITCHES, CABINETS, ETC, TO IDENTIFY THE UNIT AND THE SOURCE PANEL

AND CIRCUIT NUMBER.

12. ALL ELECTRICAL MATERIALS SHALL BE TEMPERATURE RATED FOR 90°C.

CLEAN ALL EXISTING DUCTWORK AND REPLACE ANY DAMAGES SHEET METAL AND

INSULATION. ASSUME 10' OF NEW DUCTWORK AND INSULATION.

INSTALL NEW HEAT PUMPS. OUTDOOR UNITS SHALL BE ON NEW 3" PRECAST

CONCRETE OR HPDE PAD. REFRIGERANT LINE SERVING HP-1F AND HP-2F RUNS ALONG

THE GROUND TO OPENING INTO THE BUILDING. RUN NEW REFRIGERANT LINES IN

EXISTING LOCATIONS. INDOOR UNITS SHALL BE INSTALLED IN EXISTING LOCATIONS.

RECONNECT TO EXISTING DUCTWORK AND RUN CONDENSATION TO EXISTING DRAIN.

PROVIDE NEW THERMOSTAT FOR EACH HEAT PUMP.

BALANCE AIR SYSTEM BASED ON THE CFMS ON THE FLOOR PLAN.

HEAT PUMP SHALL BE CONTROLLED BY MANUFACTURE'S INTEGRAL CONTROLS.

GENERAL NOTES:

1. THESE DRAWINGS ARE DIAGRAMMATIC IN NATURE AND NOT INTENDED TO SHOW ALL

TRANSITIONS, OFFSETS, ETC. CONTRACTOR SHALL FIELD VERIFY EXISTING

CONDITIONS AND PROVIDE ALL NECESSARY FITTINGS TO COMPLETE THE INTENT OF

THE DRAWINGS. ANY DISCREPANCIES BETWEEN DRAWINGS AND FIELD CONDITIONS

SHALL BE REPORTED TO THE CONTRACTING OFFICER FOR RESOLUTION. CONTRACTOR

MAY LOCATE MECHANICAL EQUIPMENT DIFFERENTLY THAN SHOWN ON DRAWINGS DUE

TO CONFLICTS, AS LONG AS FUNCTION AND/OR APPEARANCE ARE NOT AFFECTED.

2. ALL NEW MATERIAL, INCLUDING BUT NOT LIMITED TO DUCTWORK, PIPING, WIRING, AND

HANGERS SHALL THAT PENETRATE SURFACES SHALL USE EXISTING OPENINGS

WHENEVER POSSIBLE. IF NEW PENETRATIONS ARE REQUIRED OR EXISTING ONES ARE

ABANDONED, USE MATERIALS THAT VISUALLY MATCH IN-PLACE ADJACENT SURFACES

TO THE FULLEST EXTENT POSSIBLE. REFER TO SPECIFICATION 01 73 29 CUTTING AND

PATCHING.

ELECTRICAL NOTES:

1. ALL ELECTRICAL WORK SHALL BE PERFORMED BY AN ELECTRICIAN LICENSED IN

THE COMMONWEALTH OF VIRGINIA.

2. PRIOR TO THE START OF CONSTRUCTION, CONTRACTOR SHALL CONDUCT A

THOROUGH ASSESSMENT OF THE EXISTING ELECTRICAL SYSTEM.ENSURE

PROPOSED MECHANICAL REPLACEMENTS AND UPGRADES INTEGRATE SEAMLESSLY

WITH THE CURRENT INFRASTRUCTURE. PERFORM LOAD CALCULATIONS FOR THE

EXISTING ELECTRICAL SYSTEM TO ENSURE ADEQUATE POWER DISTRIBUTION.

ADJUST FOR NEW LOADS OR EQUIPMENT, ENSURING THE SYSTEM CAN HANDLE THE

ADDITIONAL DEMAND WITHOUT OVERLOAD.

3. ONCE EQUIPMENT AS BEEN DISCONNECTED, VERIFY THAT FEEDERS ARE

DE-ENERGIZED AND DEVICES ARE OBSOLETE AND REMOVE WIRING, RACEWAY AND

DEVICES. NOTIFY THE COR IF A FEEDER AND ASSOCIATED DEVICES ARE FOUND TO

BE FOR EQUIPMENT THAT IS.

4. FOR EQUIPMENT BEING REPLACE IN-KIND, THE ELECTRICAL CONTRACTOR SHALL

DISCONNECT POWER WIRING FROM MECHANICAL EQUIPMENT. NEATLY COIL

DISCONNECTED WIRING AND STORE IN-PLACE DURING CONSTRUCTION. AFTER NEW

EQUIPMENT HAS BEEN SET-IN-PLACE CONNECT EXISTING POWER WIRING TO NEW

EQUIPMENT.

5. FOR ALL NEW EQUIPMENT, ELECTRICAL CONTRACTOR SHALL IDENTIFY THE POWER

SOURCE, ENSURE THE PANEL HAS THE CAPACITY TO HANDLE THE ADDITIONAL

LOAD. IF AN ELECTRICAL UPGRADE IS NECESSARY, NOTIFY COR. INSTALL

DEDICATED CIRCUIT BREAKER AND PROPER WIRE FOR THE EQUIPMENT. RUN

CONDUIT AND WIRING THROUGH EXISTING PENETRATION. INSTALL LOCAL

DISCONNECT ON EQUIPMENT.
