Shop Drawings
11. Submit entire HVAC and plumbing shop drawing submittal data at one time. Submittal to be bound in three-ring binders,
indexed in a neat and orderly manner. Partial submittals will not be accepted. Submittals shall include, but not be limited to:
equipment, fixtures, insulation, diffusers and fans.
Remodel, Demolition & Unforeseen Conditions
12. 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.
13. Provide mechanical demolition required. Refer to architectural demolition drawings for location and extent of demolition
required. Visit site prior to bid to determine extent of work involved. Provide labor and materials as required to maintain and/or
restore continuity of service to existing systems.
14. In as much as design for remodel, renovation 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 and should include associated allowances in their bids noted as such.
15. Field verify locations of all existing piping, equipment, ductwork, etc.
16. Be responsible to field verify existing equipment or ductwork remaining to be reconnected to new or existing systems. Provide
ductwork, piping, controls, diffusers, etc., as required to restore continuity to system(s).
17. All ductwork, diffusers, and equipment shown on this plan are new, except where noted.
18. All new ductwork, piping, equipment, etc. is shown with dark lineweight. All existing ductwork, piping, equipment, etc. is
shown with light lineweight.
19. All existing support rods and straps now supporting ducts, pipes, air tubing, electrical conduit, etc. that are removed to allow
room for installation of new equipment shall be relocated and reinstalled, or replaced if damaged.

heater shall be activated. 2-stages of electric heat shall be controlled by 2-stage heating thermostat.
3. FAN: Fan shall run continuously during occupied periods to provide code required fresh air.
4. OUTSIDE AIR DAMPER: Normally closed MOD-1 (motor operated damper) shall open whenever fan is called to run and
shall close whenever fan is off.
ECH-1 Electric Cabinet Heater
1. HEATING: Unit shall be controlled by an integral heating thermostat, built into the unit. Heater & Fan shall automatically be
activated upon a call for heat from the unit's thermostat.
