1.11 INTENT AND REQUIRED INTERPRETATION OF THE CONSTRUCTION DOCUMENTS

A. Refer to the Article titled "Basis of Design Products and Substitutions" located elsewhere in this Section.

B. Provide complete and functional systems for the project. The systems shall conform to the details stated in these Specifications and shown on the Drawings. Items or work not shown or specified, but required for complete systems, shall be provided and conform to accepted trade practices.

C. The Drawings and Specifications are presented to define specific system requirements and serve to expand on the primary contract requirements of providing complete and functional systems. The drawings are diagrammatic and indicate the general arrangement and routing of the systems included in this Contractor's work.

D. Drawings and Specifications are intended to be complementary to each other, and contract required work only may be indicated in one of these two sources. Inclusion of a scope element in either alone, or both, obligates the Contractor to provide the indicated work.

1. References in specific Specification sections to other Sections or to the Drawings are made for the Contractor's convenience only, and the omission of a potential reference shall not be interpreted by the Contractor as invalidating the other (unreferenced) provisions.

E. All work indicated in the documents shall be completed using new equipment and materials, unless explicitly indicated otherwise.

F. The Architect / Engineer shall not be responsible for design changes or modifications except as set forth by the Architect / Engineer in writing. The Contractor shall comply with the contract documents except as directed in writing or as required by Code or manufacturer's instructions. The Contractor shall not proceed based on verbal responses by the Architect / Engineer to questions posed by the Contractor.

G. The Contractor shall include in his bid price the cost of all work that is an obvious, logical, or reasonably foreseeable consequence of other work explicitly indicated on the documents.

H. Do not scale the Drawings. Because of the scale of the Drawings, it is not possible to indicate offsets, fittings, valves, piping and duct accessories and appurtenances, or similar items which may be required to provide complete operating systems. Carefully investigate conditions affecting the work associated with this project. Check and verify dimensions and existing conditions at the site.

Install systems in such a manner that interferences between pipes, conduit, ducts, equipment, architectural and structural features are avoided. Provide items required to meet the project conditions without additional cost to the Owner.

1. Unless there are explicit notes to the contrary on piping system plans, details or diagrams, piping system layouts and diagrams are generally not intended to establish the quantity, type, and orientation of pipe elbows, tees, and caps, as the diagrams are schematic in nature and are not drawn to scale. In the event of a conflict between the graphical depictions on piping floor plans and flow diagram(s) with respect to pipe elbows, tees, and caps, the piping floor plan(s) shall take precedence.

2. Many of the required piping appurtenances, valves, small or minor piping, control devices, sensors, and similar items are omitted from floor plans and sections for clarity purposes only.

Refer to piping system enlarged plans, diagrams, details and specifications for additional

220500-8 Third & Fourth Floor Renovations required work (appurtenances) not shown on the floor plans and/or sections. The Contractor shall include in his bid price all devices shown on any one (or more) portion of the documents, as if they were shown in all locations (e.g. section, diagram, and floor plan).

I. These documents may not explicitly disclose final details required for a complete systems installation; however, contractors shall possess the expertise to include the necessary appointments of complete operating systems.

J. Manufacturer's instructions included with specified equipment shall carry the same requirements as if they were a part of this specification, unless the specification has more rigid requirements, in which case those should be followed.

K. Should a bidding Contractor find conflicts or discrepancies in, or omissions from, the Drawings or Specifications, or should he be in doubt as to their meaning, the Contractor should at once notify the Architect, who will send written instructions to all bidders. If these are ignored by the Contractor, the Contractor will be responsible for furnishing the proper or workable equipment as deemed necessary by the Architect / Engineer. The same shall apply to conflicts or discrepancies between different drawings or between different specification sections. Should no conflict or omission be brought forward or questioned, it will signify the contractors' acceptance and understanding of the documents.

L. Details shown on the Drawings shall apply to all instances of such item or condition indicated elsewhere on the Drawings, with or without an explicit reference thereto.

M. The Drawings and Specifications primarily indicate the work that is required by Contract. In selected instances, an indication of work that is NOT acceptable may be made in the Contract documents order to provide additional emphasis or clarity. The omission of a similar statement elsewhere in the Documents shall not be construed by the Contractor to mean that unspecified or unindicated work will be accepted or is permitted under this Contract.

N. Where names of manufacturers of products are listed in the Specifications, the mere listing of a manufacturer's name does not relieve the Contractor of the obligation to meet all provisions of the Contract documents. All proposed products, even of those of manufacturers listed in the Specifications, are subject to the requirements of the Contract, and therefore are only acceptable provided that they meet the requirements of the Contract, as interpreted by the design professionals (Architect and Engineer).

O. Where a code or standard is referenced, unless explicitly indicated otherwise, it shall be taken to refer to the most recent published version / edition at the time of bidding.

P. In cases where equipment and materials are specified in the singular or plural number, it is intended that such reference shall apply to as many such items as are required to complete the installation.

1.12 TEMPORARY SHUTDOWN OF EXISTING SYSTEMS

A. Plan installation of new work and connections to existing work to insure minimum interference with regular operation of existing systems. Some temporary shutdown of existing systems may be required to complete the work.

B. Submit to the Owner in writing for approval, proposed date schedule, time, and duration of necessary temporary shutdowns of existing systems. Submit schedule at least five working days in advance of intended shutdown or as indicated in Division 01. Shutdowns shall be made at such times as shall not interfere with regular operation of existing facilities and only after written approval of Owner. The Owner reserves the right to cancel shutdowns at any time prior to the shutdowns.

220500-9 Third & Fourth Floor Renovations

To minimize conflict with Owner's operation, shutdowns shall be planned to occur on weekends. To insure continuous operation, make necessary temporary connections between new and existing work. The Contractor shall bear costs resulting from temporary shutdowns and temporary connections. No additional charges shall be allowed for Owner-canceled shutdowns that must be rescheduled.

1.13 BASIS OF DESIGN PRODUCTS AND SUBSTITUTIONS

A. Throughout the project specifications and drawings, materials and equipment may be indicated as the "basis of design" material or equipment. If the bidding Contractor desires to furnish equipment of a manufacturer other than that which is indicated to be the "basis of design", even if alternative manufacturer and product names are also listed, it is the full burden of the bidding Contractor to verify, prior to submitting a bid price, that the proposed product meets all of the project requirements and specifications. Any changes to the work, including changes to the work of other trades / Divisions, shall be borne by the Contractor at no additional cost to the Owner, and the proposed changes shall meet with the approval of the Architect / Engineer.

1. Bidders may elect, during the bidding period, to request the Architect / Engineer's pre-approval, in writing, to substitute such item for the specified item and shall submit supporting data and samples if required, to permit a fair evaluation of the proposed substitution with respect to quality, serviceability and warranty. This request shall be made no less than 10 days prior to the Bid Date.

2. When submitting for approval a product that was not listed as the basis of design, the Contractor shall explicitly indicate the following in the submittal:

a. All changes to the work which is required to accommodate the substitution. If no changes are required, then this should be stated instead. The Contractor is responsible for coordinating these changes with the affected trades.

b. All deviations from the contract requirements.

c. Compliance Report: Along with each submission copy of the product data and/or shop drawing, the manufacturer shall indicate the necessary modifications to the product and/or system to satisfy the requirements of the Contract Documents. Each paragraph including all subparagraphs shall bear the same paragraph number as the contract specification so that a close comparison can be made to the manufacturer specified herein by catalog number(s).

d. Each paragraph for the substituted product/system shall be identified as follows:

1) Comply: The…
