1. Immediately notify the Engineer of any discrepancies.
2. Work shall be performed in a workmanlike manner to the satisfaction of the Architect & the Engineer.
3. Labor, materials, and equipment shall conform to the latest applicable editions of local, State of Colorado, and National Codes and ordinances.
If conflict between those publications exists, the most stringent requirement shall apply.
4. Provide record drawings to architect. Drawings shall include all addendum items, change orders, alterations, re-routings, etc.
5. The drawings show the intent of the mechanical systems but do not show all details required. It is the responsibility of the Contractors to install
complete & operable systems, which conform to the manufacturers' installations instructions & industry standards.
6. Systems shall be tested for proper operation. If tests show work is defective, Contractor shall make corrections necessary at no cost to Owner.
7. Systems shall be professionally labeled. Piping shall be labeled with color coded commercial grade labels indicating piping service and flow
direction. Equipment, pumps and valves shall be labeled with engraved plastic or metal tags and an equipment/valve schedule shall be provided
and mounted on the mechanical room wall. Equipment labels shall follow the same nomenclature as the mechanical drawings.
8. Offset piping, ductwork, etc. as necessary to accommodate structure, beams, columns, and existing equipment.
Shop Drawings
9. 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, insulation, pumps, fans,
piping, valves and boilers.
Remodel, Demolition & Unforeseen Conditions
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. 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.
12. 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.
Insulation
13. Insulate all new heating water piping (mains and runouts to areas being heated) with U.L. approved, white, all service, glass fiber, snap-on, pipe

with Armaflex.
14. Insulation for all types of piping shall be carried full size through pipe hangers or pipes shall be supported with vibration clamps. Provide metal
cradle at hangers to protect insulation from crushing.
Piping
15. Heating Water piping - Type 'L' copper, wrought copper fittings, and no lead solder.
16. Dielectric Unions - Furnish and install a dielectric union at all connections where non-ferrous material is in contact with ferrous material and
fluid is not protected with corrosion inhibitors.
