CONTRACT DOCUMENTS.

2. DRAWINGS SHALL BE CONSIDERED DIAGRAMMATIC AND ARE INTENDED TO

INDICATE CAPACITY, SIZE, APPROXIMATE LOCATION AND GENERAL ARRANGEMENT.

WHILE THE DRAWINGS ARE GENERALLY TO SCALE AND ARE AS ACCURATE AS THE

SCALE WILL PERMIT, DIMENSIONS SHALL BE CONFIRMED IN THE FIELD.

3. THE CONTRACTOR SHALL COMPLY WITH THE LAWS, ORDINANCES, RULES AND

REGULATIONS OF LOCAL AND STATE GOVERNMENTAL AUTHORITIES; OF THE

NATIONAL FIRE PROTECTION ASSOCIATION AS INTERPRETED BY THE ENFORCING

AUTHORITY HAVING JURISDICTION; AND OF PUBLIC UTILITIES HAVING CONNECTION

WITH ANY OF THE SYSTEMS HEREIN SPECIFIED.

4. INSTALL EQUIPMENT IN A SERVICEABLE MANNER WITHOUT DISRUPTION TO

ADJACENT SERVICES OR DAMAGING INSULATION. THIS INCLUDES, BUT IS NOT

LIMITED TO: PROVIDE VALVE OPERATOR EXTENSIONS TO EXTEND THRU THE

INSULATION AND HANDLES TO SWING TOWARD THE OPERATOR FOR ISOLATION.

5. PROVIDE ALL NEW AND REUSED WALL PENETRATIONS WITH A SLEEVE/CONDUIT

FOR SERVICES PENETRATING IT. THIS INCLUDES, BUT IS NOT LIMITED

TO: DUCTWORK, PIPING, POWER, AND CONTROL WIRING.

6. THE CONTRACTOR SHALL SECURE AND PAY FOR ALL PERMITS AND INSPECTIONS

REQUIRED BY ANY OF THE FOREGOING AUTHORITIES, AND PAY FOR ALL OTHER

COSTS IN CONNECTION WITH THE WORK. CERTIFICATES SHALL BE IN DUPLICATE

AND SHALL BE DELIVERED TO THE OWNER.

7. THE SITE, LOCATION, AND ROUTING OF SYSTEMS INDICATED TO HAVE NEW

CONNECTIONS MADE TO THEM ARE SHOWN AS ACCURATELY AS FIELD CONDITIONS

PERMIT. CONTRACTOR SHALL VISIT THE SITE AND THOROUGHLY EXAMINE THE

CONTRACT DRAWINGS. ALL EXISTING CONDITIONS SHALL BE EXAMINED AND THEIR

EXACT LOCATIONS VERIFIED. THE CONTRACTOR SHALL REPORT TO THE ENGINEER

ANY CONDITIONS WHICH MIGHT MAKE INSTALLATION OF REQUIRED EQUIPMENT A

PROBLEM. NO CONSIDERATION OR ALLOWANCE WILL BE GRANTED FOR FAILURE

TO INVESTIGATE CONDITIONS OR MISUNDERSTANDINGS OF THE CONTRACTUAL

REQUIREMENTS.

8. THE CONTRACTOR SHALL INSTALL AND CONNECT EQUIPMENT AND MATERIALS IN

ACCORDANCE WITH THE BEST ENGINEERING PRACTICE AND, UNLESS OTHERWISE

MAGNITUDE WHICH INVOLVE EXTRA COSTS SHALL NOT BE MADE WITHOUT

WRITTEN APPROVAL.

15. ALL DIMENSIONS FOR EXISTING PIPING AND DUCTWORK SHALL BE VERIFIED IN THE

FIELD BY THE CONTRACTOR PRIOR TO CONSTRUCTION, WHERE NEW WORK

CONNECTIONS ARE INDICATED. NEW DUCT DIMENSIONS SHOWN ARE INSIDE CLEAR

DIMENSIONS.

16. OPENINGS REMAINING IN EXISTING PIPING/DUCTWORK AS A RESULT OF

DEMOLITION SHALL BE SEALED WITH AN AIRTIGHT/WATERTIGHT SHEET METAL CAP.

WHERE EXISTING SYSTEMS ARE INSULATED, WORK SHALL INCLUDE REPAIR AND

REPLACEMENT OF INSULATION EITHER DAMAGED OR REMOVED AS A RESULT OF

DEMOLITION.

17. PIPING SCOPE REQUIREMENTS: HORIZONTAL DRAINAGE PIPING SHALL BE

INSTALLED IN UNIFORM ALIGNMENT AT UNIFORM SLOPES. THE MINIMUM SLOPE OF

HORIZONTAL DRAINAGE PIPE SHALL BE IN ACCORDANCE WITH THE FOLLOWING:

SIZE (INCHES) MINIMUM SLOPE (INCHES PER FOOT)

2-1/2 OR LESS 1/4

3 TO 6 1/8

8 OR LARGER 1/16
