SECTION 22 00 11

GENERAL PROVISIONS

PART 1 GENERAL

1.01 CONDITIONS OF THE CONTRACT

A. The Conditions of the Construction Contract and applicable provisions of Division l - General Requirements, as well as these General Provisions, shall apply to all Sections of Division 22.

1.02 SCOPE

A. The work to be done under this Division of the Specifications shall include the furnishing of all labor, materials, equipment and services necessary for the proper completion of all of the mechanical work as shown on the drawings and herein specified.

B. In general, this shall include the furnishing and installing of all fire protection, plumbing, heating, refrigeration, ventilation, and temperature control systems, complete with auxiliaries, as may be required to make a complete and properly operating installation.

C. Only such items as are hereinafter specified or indicated on the drawings to be furnished by others, shall be considered to be furnished by others. All other items are to be considered as a part of this Contract, and shall be so bid.

D. The omission of specific reference to any parts necessary to, or reasonably incidental to, a complete installation shall not be construed as releasing the Contractor from furnishing and installing same.

E. Applicable provisions of the following sections shall apply to all sections for Mechanical Work.

1.03 DEFINITIONS

A. Provide: Under this Contract, Contractor shall furnish and install item or items specified.

Contractor shall perform all labor and furnish all materials and equipment necessary to that specified item or system will be complete and operational in every respect.

B. Furnish: Under this Contract, Contractor shall deliver to the site item(s) specified, as well as additional specialized materials and/or accessories necessary for the use and operation of item or items specified.

C. Install: Under this Contract, Contractor shall set in position, connect (including sub-assemblies furnished), and adjust for use. Contractor shall furnish miscellaneous specialty items such as hangers, valves, unions, piping, sheet metal, etc., as obviously necessary for a complete and operating installation.

1.04 DRAWINGS

A. In general, the drawings of the Mechanical Systems and Equipment are to scale, however, to determine exact locations of walls and partitions, the Contractor shall consult the Architectural and/or Structural Drawings which are dimensioned. Drawings shall not take precedence over field measurements. Plans of piping and ductwork, although shown on scale drawings, are diagrammatic only. They are intended to indicate the size and/or capacity where stipulated, approximate location and/or direction, and approximate general arrangement of one phase of work to another, but not the exact detail or exact arrangement of construction.

B. Where discrepancies are discovered after certain portions or phases of any Contract have been installed, the Contracting Officer reserves the right to have any or all Contractors make minor changes in pipe, duct, fixture or equipment locations or arrangements to avoid conflict with other work at no additional cost to the Owner.

C. Because the drawings are to a relatively small scale to show as large a portion as is practical, the fact that only certain features of the system are indicated does not mean that other similar or different features or details will not be required. Contractor shall furnish all incidental labor, materials, or equipment for the systems under his control, so that each system is a complete and operating one unless otherwise specifically stipulated in the detailed body of the Specifications.

15037 / Toumey Nursery 22 00 11 - 2 GENERAL PROVISIONS

D. The Contractor shall be responsible for determining all field measurements before commencing construction, giving due consideration to building design and other equipment to be installed.

Mechanical equipment not dimensioned on the drawings shall be field located, giving due consideration to the work of other trades. The Contractor shall verify all dimensions before proceeding with the work. Where cutting and patching is required, each Contractor shall be responsible for his own work.

E. Dimensions shall not be scaled from the drawings. If the Contractor discovers any discrepancy between actual measurements and those shown on the drawings which prevents good practice, good arrangement, or which is contrary to the intent of the drawings and specifications, he shall notify the Contracting Officer before proceeding with the work.

1.05 SITE INSPECTION

A. Before submitting a proposal for the work contemplated in these specifications and accompanying drawings, each bidder shall examine the site and familiarize himself with all the existing conditions and limitations, including the extent of demolition, cutting and patching to be done by the Contractor for Mechanical Work. No extras will be allowed because of the Contractor's misunderstanding as to the amount of work involved, or his lack of knowledge of any condition in connection with the work.

B. Locate existing piping and make connection where required and/or where shown on the drawings. Do not cut into existing services without first ascertaining to the satisfaction of the Owner and Contracting Officer's Representative that the pipe involved is the desired service. In any area where work performed under Division 22 is the only work involved, restore the area to its original condition upon completion of the work.

15037 / Toumey Nursery 22 00 11 - 6 GENERAL PROVISIONS

C. All existing services and equipment shall be maintained unless otherwise indicated on the drawings.

D. Work that interrupts any service (this includes cutting into existing lines for new connection), shall be performed at times (usually nights or weekends) to cause least interference to the normal operation of the building. Anticipate scheduling work at periods which will result in additional construction costs, such as nights or weekends, and include cost in the proposal.

E. The Owner shall be fully informed in advance of any shut-off which will occur and which will be affected for a specific period of time. Only after the Owner is fully informed and has agreed to the schedule of cut-offs, can the work then proceed accordingly.

F. Provide temporary bracing, shoring, underpinning and support during demolition, cutting, remodeling and related new construction as necessary for the execution of the Work and the protection of persons and property.

G. Provide protective coverings and enclosures necessary to prevent damage to existing work to remain. Protect temporary openings in exterior walls and roofs so as to prevent damage from water and the elements and prevent excessive heat loss from the existing building.

H. Demolish and remove existing construction to be removed.

I. Clean demolition areas and remove debris, waste and rubbish from the building at the conclusion of each day's work. Transport debris and rubbish in such a manner as to prevent the spread of dust. Remove debris, waste and rubbish promptly from the site. Do not burn debris, waste and rubbish on the site.

J. Owner shall have first rights to salvage existing equipment not indicated to be reused. All existing materials not designated to be reused or to remain the property of the Owner, shall become the property of the Contractor and shall be removed from the site.

K. Existing materials indicated on the drawings to be reused shall be stored on the site and protected until reuse.

L. All cutting and patching of existing construction shall be by the Contractor requiring same.

M. Prior to making any cuts, verify exact locations and sizes with the Contracting Officer's Representative to confirm that no structural members will be cut. Where required, Contractor shall provide reinforcing lintels, angles, supports, etc., as necessary to maintain structural integrity at penetrations of existing partitions, slabs, etc.

N. Patch existing construction to match. All painting shall comply with the specifications laid out in the General Contractor's portion of the specifications. Examine existing surfaces where existing surfaces are to be patched before proceeding with the work. Report all conditions where existing materials, colors, and finishes cannot be matched to the Contracting Officer's Representative, and do not proceed until the Contracting Officer's Representative has issued instructions. Existing construction that has been damaged as a result of the work shall be repaired to an extent and as required to match adjacent undamaged construction. Contractor shall notify Contracting Officer's Representative when patching is complete and receive Contracting Officer's Representative approval of patching and finish

O. Where duct and/or piping is removed from existing partitions which are to remain, it is this Contractor's responsibility to patch voids to match existing construction.
