7. Systems shall be tested for proper operation. If tests show work is defective, contractor shall make
corrections necessary at no cost to owner.
8. Coordinate architectural, structural, electrical, landscaping, fire protection, and interior design drawings
with mechanical drawings prior to installation.
9. Offset piping, ductwork, etc. as necessary to accommodate structure, beams, columns, and existing
equipment.
Remodel & Demolition
10. Visit site prior to bid and verify the conditions. Include in the bid, costs required to make work meet
existing conditions, whether indicated or not.
11. In as much as design for remodel and/or rehabilitation requires that certain assumptions be made
regarding existing conditions and because some of these assumptions cannot be verified without
destroying otherwise adequate or serviceable portions of the building. The engineer cannot assure the
owner or the contractor that the professional consulting services herein encompass all contingencies.
Field coordination during construction is imperative. Contractors bidding this work must make
reasonable allowances for unseen conditions.
12. Field verify locations of all existing piping, equipment, ductwork, etc.
13. All new ductwork, piping, equipment, etc. is shown with dark lineweight. All existing ductwork, piping,
equipment, etc. is shown with light lineweight.
Insulation
14. Insulate all new piping to match the insulation being installed for the base building systems (white
fiberglass type). Minimum insulation thickness per 2009 IECC table 503.2.8 is 1.5" for both heating
water and chilled water piping (1.5" piping diameter and less). Insulate all heating water, chilled water,
domestic cold water, domestic hot water and domestic hot water recirculation piping.
15. ,QWHUQDOO\OLQHDOOQHZUHFWDQJXODUGXFWZRUNZLWK´DFRXVWLFDOGXFWOLQHUߛ5߰PLQLPXPߜXQOHVVQRWHG
otherwise. Some locations may have 2" insulation specified for additional sound attentuation.
16. Externally wrap all outside air and relief air ductwork as well as all unlined supply air ductwork and the
bypass duct (if applicable) with 2" duct wrap with vapor barrier. Minimum R-value shall be 6.5.
Piping

balancing/shut-off valve, Hoffman, Sarco, or equivalent.
23. Support pipe with rod and clevis or clamps. No pipe tape allowed.
24. Dielectric Unions - Furnish and install a dielectric union at all connections where non-ferrous material is
in contact with ferrous material and fluid in not protected with corrosion inhibitors.
25. Install plumbing clean-outs as required by applicable codes.
Ductwork
26. Duct sizes shown on drawings are outside (sheet metal) duct dimensions.
27. Seal all ductwork joints and vapor barrier penetrations at all exterior walls.
28. Provide backdraft dampers at any and all ductwork penetrations through exterior wall (except outside air
and combustion air ductwork).
29. Provide turning vanes in all mitered rectangular elbows.
30. Provide volume dampers at all accessible round duct take-offs.
31. Make all final connections to supply GRD's with acoustic flexible duct. Maximum length shall be 8 feet.
32. All ductwork or surfaces which are visible behind a grille, register, or diffuser shall be painted flat black.
33. Sheet metal and fittings to be pursuant to SMACNA and ASHRAE standards.
34. Seal off all ducts during construction.
Controls
35. Mount all thermostats 5'-0" above finished floor.
36. All thermostats shall have a temperature range suitable for the application and have adjustable set points.
The thermostats shall be able to display temperature setpoint and room temperature. All thermostats shall
be approved by the owner.
37. Freeze Detection Thermostats. Each supply system with water coils taking outside air shall have a freeze
detection thermostat located on the downstream side of the coil. Thermostats shall be of adjustable
