THE DRAWINGS ARE DIAGRAMMATIC AND INDICATE GENERALLY THE LOCATION OF MATERIALS AND EQUIPMENT. THE CONTRACTOR SHALL PROVIDE ALL LABOR, EQUIPMENT, AND MATERIALS, UNLESS OTHERWISE NOTED, TO HAVE A COMPLETE AND FUNCTIONING SYSTEM. "PROVIDE" SHALL MEAN TO FURNISH AND INSTALL.

ALL SERVICES THAT ARE INTERRUPTED OR DISCONNECTED SHALL BE REROUTED AND RECONNECTED IN ORDER TO PROVIDE A COMPLETE INSTALLATION.

THE WORK SHALL BE DONE IN ACCORDANCE WITH THE LOCAL BUILDING CODES, NFPA AND ALL OTHER APPLICABLE STATE AND FEDERAL CODES.

FINAL LOCATION OF EQUIPMENT AND CONNECTION POINTS SHALL BE DETERMINED IN THE FIELD WITH THE CONTRACTOR BEING RESPONSIBLE FOR DIMENSIONS THAT SHALL BE CONFIRMED AND CORRELATED AT THE JOB SITE.

INSTALL EQUIPMENT SO AS TO BE READILY ACCESSIBLE FOR OPERATION, MAINTENANCE, AND REPAIR. MINOR DEVIATIONS FROM THE DRAWINGS MAY BE MADE TO ACCOMPLISH THIS, BUT CHANGES WHICH INVOLVE EXTRA COST SHALL NOT BE MADE WITHOUT PRIOR APPROVAL OF THE OWNER OR CONSTRUCTION MANAGER.

FOR RENOVATION WORK, A CONTRACTOR'S SUBMISSION OF A BID SHALL BE CONSTRUED AS EVIDENCE THAT A CAREFUL EXAMINATION OF THE PORTIONS OF THE EXISTING BUILDING, EQUIPMENT, ETC., WHICH AFFECT THIS WORK AND THE ACCESS TO SUCH SPACES, HAS BEEN MADE AND THAT THE CONTRACTOR IS FAMILIAR WITH EXISTING CONDITIONS AND DIFFICULTIES THAT WILL AFFECT THE EXECUTION OF THE WORK. LATER CLAIMS SHALL NOT BE MADE FOR ADDITIONAL LABOR, EQUIPMENT OR MATERIALS BECAUSE OF DIFFICULTIES ENCOUNTERED WHICH COULD HAVE BEEN FORESEEN DURING SUCH AN EXAMINATION.

THE CONTRACTOR SHALL OBTAIN AND PAY FOR ALL PERMITS AND INSPECTIONS REQUIRED FOR THE EXECUTION OF THIS WORK AND SHALL OBTAIN NECESSARY APPROVALS FROM AUTHORITIES THAT HAVE JURISDICTION.

THE CONTRACTOR SHALL BE RESPONSIBLE FOR ALL CORING NEEDS FOR PASSAGE OF PIPING THROUGH SOLID CONCRETE WALLS, FLOORS OR FOUNDATION WALLS.

THE CONTRACTOR SHALL BE RESPONSIBLE FOR HANDLING, STORAGE, RIGGING AND SETTING OF ALL EQUIPMENT AND MATERIALS. CRANES, LIFTS, HOIST AND SCAFFOLDING OF ALL EQUIPMENT SHALL BE EMPLOYED AS REQUIRED TO COMPLETE THE INSTALLATION.

INFORMATION SHOWN ON FLOW DIAGRAMS AND DETAIL DRAWINGS BUT NOT SHOWN ON FLOOR PLANS, AND VICE VERSA, SHALL MUTUALLY APPLY. IT IS NOT INTENDED TO SHOW EVERY OFFSET, FITTING OR COMPONENT; HOWEVER, THE CONTRACTOR SHALL PROVIDE A COMPLETE INSTALLATION AS NECESSARY.
