Include the following information, as applicable: a. Use applicable Drawings as a basis for preparation of coordination drawings. Prepare sections, elevations, and details as needed to describe relationship of various systems and components. b. Coordinate the addition of trade-specific information to the coordination drawings by multiple contractors in a sequence that best provides for coordination of the information and resolution of conflicts between installed components before submitting for review. c. Indicate functional and spatial relationships of components of architectural, structural, civil, mechanical, and electrical systems. d. Indicate space requirements for routine maintenance and for anticipated replacement of components during the life of the installation. e. Show location and size of access doors required for access to concealed dampers, valves, and other controls. f. Indicate required installation sequences.

Mechanical and Plumbing Work: Show the following: a. Sizes and bottom elevations of ductwork, piping, and conduit runs, including insulation, bracing, flanges, and support systems. b. Dimensions of major components, such as dampers, valves, diffusers, access doors, cleanouts and electrical distribution equipment. c. Fire-rated enclosures around ductwork. 7. Electrical Work: Show the following: a. Runs of vertical and horizontal conduit 1-1/4 inch diameter and larger. b. Light fixture, exit light, emergency battery pack, smoke detector, and other fire alarm locations. c. Panel board, switch board, switchgear, transformer, busway, generator, and motor control center locations. d. Location of pull boxes and junction boxes, dimensioned from column center lines. 8. Review: Architect will review coordination drawings to confirm that the Work is being coordinated, but not for the details of the coordination, which are the Contractor's responsibility. If the Architect determines that the coordination drawings are not being prepared in sufficient scope or detail, or are otherwise deficient, the Architect will so inform the Contractor, who shall make changes as directed and resubmit. 9. Coordination Drawing Prints: Prepare coordination drawing prints in accordance with requirements of Division 01 Section "Submittal Procedures." C. Coordination Digital Data Files: Prepare coordination digital data files in accordance with the following requirements: 1. File Preparation Format: Same digital data software program, version, and operating system as the original Drawings. 2. File Preparation Format: DWG Version AutoCAD 2011 or higher, operating in Microsoft Windows operating system. 3. File Submittal Format: Submit or post coordination drawing files using format same as file preparation format. Thornwood Commons Electrical and Plumbing Upgrades PROJECT MANAGEMENT AND COORDINATION

26 4. Architect will furnish Contractor one set of digital data files of the Drawings for use in preparing coordination digital data files. 1.6 KEY PERSONNEL a. Architect makes no representations as to the accuracy or completeness of digital data files as they relate to the Drawings. b.
