1.4 SCOPE

A. Drawings and Specifications form complementary requirements; provide work specified and not shown, and work shown and not specified as though explicitly required by both.

Although work may not be specifically shown or specified, provide supplementary or miscellaneous items, appurtenances, devices and materials obviously necessary for a sound, secure and complete installation.

B. It is the intent that these Specifications and associated Drawings establish minimum requirements for products and equipment with the intent to provide plumbing systems finished, tested and ready for operation. Incidental detail that is not shown or specified, but necessary for proper installation and operation shall be included in the work and in these Contractor's estimates, the same as if specified. Locations of all equipment and material shall be adjusted at no extra cost to the Owner, to accommodate the work interferences anticipated and/or encountered. Prior to installation, determine the exact route and location of each pipe and piece of equipment to minimize conflicts with other trades.

C. This project will be phased, as defined by the Owner. This may necessitate the provision of temporary valving and capping of Plumbing utilities. All associated appurtenances with the utilities shall be provided as part of this project in the appropriate phase coordinated with Owner’s phasing requirements.

D. Information and components shown on riser diagrams but not shown on plans, and vice versa, shall be provided as if expressly required on both.

E. It is the requirement of these Contract Documents to have the contractors provide systems and components that are fully complete, operational and suitable for the intended use.

There may be situations in the documents where insufficient information exists to precisely describe a certain component or subsystem, or the routing of a component or its coordination with other building elements. In cases such as this, where the Contractor has failed to notify the Architect of the situation the Contractor shall include the specific components or subsystems with all parts necessary for the intended use, fully complete and operational, and installed in workmanlike manner either concealed or exposed per the design intent.

1.5 MODIFICATIONS IN LAYOUT

A. Drawings are intended to outline the scope of work required and are not intended to be installation drawings. Drawings are not intended to be absolutely precise; they are not intended to specify or to show every offset, fitting, and component nor do they show the exact routing and locations needed to coordinate with structure and other trades and to meet Architectural requirements. The purpose of the drawings is to indicate a systems concept, the main components of the systems, and the approximate geometrical relationships. Drawings do not necessarily show the exact routings and locations needed to fully coordinate with structure and other trades to meet Architectural requirements. Based on the systems concept, the main components, and the approximate geometrical relationships, the contractor shall provide all other components and materials necessary to make the systems fully complete and operational.

B. Unless specifically stated to the contrary, no measurement of a drawing derived by scaling shall be used as a dimension to work by. Dimensions noted on the drawings are subject to measurements of adjacent and previously completed work. Measurements shall be performed prior to the actual installation of equipment.

COMMON WORK RESULTS FOR PLUMBING 220500 - 4

C. Prior to installation of visible material and equipment (including access panels) in finished spaces, review Architectural Drawings for desired locations and where not definitely indicated, request information from Architect.

D. Check Contract Documents, as well as, Submittals and Shop Drawings of all subcontractors to verify and coordinate spaces in which work of Divisions 21 through 28 will be installed.

E. Make reasonable modifications in layout and components needed to prevent conflict with work of other trades. Systems shall be run parallel with or perpendicular to major architectural and structural building elements.

F. Where conflicts or potential conflicts exist and engineering guidance is desired, submit sketch of proposed resolution to Architect for review and approval.

1.6 COORDINATION

A. Coordinate arrangement, mounting, and support of piping and equipment:

1. To maintain maximum headroom; all piping, duct, conduit and associated components to be as tight as possible to underside of structure to provide for ease of disconnecting the equipment with minimum interference to other installations.

2. To allow right of way for piping installed at required slope.

3. To be clear of obstructions and of the working and access space of other equipment.

B. Coordinate installation of required supporting devices and set sleeves in cast-in-place concrete, masonry walls, and other structural components as they are constructed.

C. Coordinate location of access panels and doors for electrical items that are behind finished surfaces or otherwise concealed. Access doors and panels are specified by the architect.

Locations of access doors are to be shown on coordination drawings and approved by the Architect prior to installation.

1.7 COORDINATION DRAWINGS

A. When included as part of the Contract Documents, there shall be full cooperation and coordination of all specialty trades.

B. This Division’s contractors shall comply fully with the requirements set forth in the Division 23 “BIM Coordination Drawings” specification section.

1.8 RECORD DOCUMENTS

A. Record Drawings are specified in Division 01 Section "Project Record Documents."

B. The Contractor shall keep a detailed up-to-date record, of the manner and location in which installations are actually made, indexing pipe, valve, and piece of equipment. Record documents are to reflect all changes in work including change orders, field directives, addenda from bid set of Contract Documents, request for information responses, etc. Upon completion of the project, the contractor shall modify the project electronic drawing and specification files to incorporate this information.
