SECTION 15000

MECHANICAL GENERAL PROVISIONS

PART 1 - GENERAL

1.1 WORK INCLUDED

A. This section applies to all Division 15 (mechanical) work.

B. The general provisions of the Contract, including General and Supplementary Conditions and General

Requirements applies to all Division 15 work.

C. Each specification section within their respective Division shall be coordinated with all other sections in that division for related work.

D. The project documents contemplate the complete installation of the systems described herein, or shown on the drawings, so that at the conclusion of the construction, the systems will be turned over to the Owner complete and ready for safe, efficient operation.

E. The Contractor shall be obliged to furnish and install all such items normally included on systems of this type, which while not mentioned directly herein are obviously essential to the installation and operation of the systems, and which are normally furnished on installations of this type.

1.2 COORDINATION OF WORK

A. General: Refer to the Division 1 sections for general coordination requirements applicable to the entire work. The Contractor shall recognize that the Contract Documents are diagrammatic in showing certain physical relationships that must be established within the mechanical and electrical work, and in its interface with other work including utilities and that such establishment is the exclusive responsibility of the Contractor. This Contractor shall be responsible for work fitting in place without conflict with other trades, where proper planning could avoid interference. This Contractor shall examine the locations and verify all measurements, distances, elevations and existing conditions before starting work. Because the drawings are diagrammatic and on a small scale, all rises, drops, offsets, etc., have not been shown. The Contractor shall agree to provide and install the necessary piping, fittings, valves, ducts, duct fittings and offsets, and other specialties to suit such conditions without additional cost to the Owner. Mechanical drawings shall not be used for general construction dimensions or for type of material used for general construction. For exact building layout, dimensions and building materials used, Contractor shall refer to Architectural Drawings.

1.3 QUALITY ASSURANCE

A. Contractor shall comply with all State, and local codes and ordinances.

B. Contractor shall make application for, obtain and pay for all required permits and certificates of inspection of the work.

C. All equipment, materials, and installation procedures shall comply with standards listed within each

Division 15 section.

D. Verify final locations for rough-ins with field measurements and with the requirements of the actual equipment to be connected.

15000-2

E. Install equipment and materials to provide required access for servicing and maintenance.

1.4 SUBMITTALS

A. See 1B "Shop Drawings" for shop drawing submittal list.

B. Maintenance and Operation Manuals:

1. Prepare and submit three (3) copies of maintenance and operation instructions for all

Division 15 equipment furnished. Organize maintenance and operating manual information into suitable sets of manageable size, and bind into individual binders properly identified and indexed (thumb-tabbed). Include emergency instructions, spare parts listing, copies of warranties, wiring diagrams, recommended "turn-around" cycles, inspection procedures, shop drawings, product data, signed letters of certification of inspection and similar application information. Bind each manual of each set in a heavy-duty 2-inch, 3-ring vinyl-covered binder, and include pocket folders for folded sheet information. Mark identification on both front and spine of each binder.

C. Record Drawings:

1. Provide one (1) set of mechanical drawings marked-up with actual installation locations for

Division 15 work. Give special attention to the complete and accurate recording of underground conduit, piping and ductwork, other concealed and non-accessible work, branching arrangement and valve location for piping systems, locations of dampers and coils in duct systems, locations of control system sensors and other control devices, and work of change orders where not shown accurately by Contract Documents.

D. Contract Document Discrepancies:

1. If Contract Document requirements appear to make it impossible to produce first class work, or should discrepancies appear among Contract Documents, request interpretation before proceeding with work. If Contractor fails to make such request, no excuse will thereafter be entertained for failure to carry out work in satisfactory manner. Should conflict occur in or between drawings and specifications, Contractor is deemed to have estimated on more expensive way of doing work unless he shall have asked for and obtained written decision before submission of proposal as to method or materials required.

E. The Contractor shall be responsible for and bear any expense of alterations to the building or its appurtenances resulting from the substitution of equipment to that specified in the Contract

Documents.

F. Review of shop drawings does not release the Contractor from further satisfactory operating responsibilities. Material and equipment shall still be required to meet the requirements of the

Construction Documents and shall be approved for final acceptance when construction is completed and all units and systems have been operated, tested, adjusted and balanced to the satisfaction of the

Architect/Engineer. Should proposed approved alternate equipment involve rearrangement of designed equipment, a complete layout of the area involved shall be submitted by the Contractor, and shall be approved in writing before installation of any such items of equipment. Any additional expense involved shall be a Contractor-borne expense.

15000-3

1.5 FEES, PERMITS, LICENSES, UTILITY CONNECTION CHARGES, AND UTILITY COST

A. The Contractor shall obtain and pay for all fees, permits, licenses, utility connection charges (water, sanitary sewer, storm sewer and gas) and utility cost for services to the building required.
