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. If it is found before installation of any or all construction phases, that a more convenient, suitable or workable arrangement of any or all phases of the project would result by varying or altering the arrangement indicated on the drawings, the Architect may require any or all Contractors to change the location or arrangement of their work without additional cost to the Owner. Such rearrangement shall be in accordance with directions from the Architect.

C. Where discrepancies are discovered after certain portions or phases of any Contract have been installed, the Architect 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.

D. 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.

E. 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.

F. 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 Architect before proceeding with the work.

3.05 REMODELING

A. Relocation of existing equipment and piping systems, which of necessity must provide continuous uninterrupted service, shall be accomplished in the least possible time. Work shall be scheduled so as to minimize down time for the respective systems involved. This will require for existing services being revamped and/or relocated, that all interconnecting portions of these systems shall be installed as complete as practicable prior to actual shutdown for final connections.

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 Engineer 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.

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. Where new Work is to be installed in or adjacent to existing construction or existing work is to be replaced, remove or cut the existing construction to the extent necessary to install or join the new Work to the existing construction as necessary to complete the Work of the Project.

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.

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 Architect 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 Engineer, and do not proceed until the Engineer 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

15031 / MN Interagency Fire Center 22 00 11 - 7 adjacent undamaged construction. Contractor shall notify Architect when patching is complete and receive Architect's 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.
