Also show all wall mounted items located within 12" of the ceiling plane, and show all access panels required.
B. Subcontractor is to coordinate the software to be used to ensure it is compatible with the rest of the project team/subcontractors and to allow for merging into one project master file.
PART 2 – GENERAL - (Coordination Process)
Subcontractor agrees to comply with the following drawing coordination process;
C. 3D object models shall be utilized to establish installation sequence, resolve trade coordination issues prior to installation and to make the most efficient use of space allocated for systems such as building structure/mechanical/electrical/plumbing/fire protection and enclosure installations without sacrifice to systems performance. This is also required to determine inter-relationships and possible interference’s between all of the trades' Work and the architectural or structural features. D. Subcontractors are required to attend coordination meetings as required by Leopardo Companies, Inc.. The representative(s) from each Subcontractor is required to be familiar with the Work and have the expertise and authority to answer questions and make decisions and changes to its systems at these meetings. E. The 3D models may also be used by Subcontractor as part of its required shop drawing and as-built drawing submittals. In regard to as-built drawings, in the event the actual installation varied from the approved shop drawings, subcontractor agrees to amend the model accordingly prior to submission of as- built information. F. Each subcontractor should anticipate that each floor may require several meetings. However, in the interest of time, multiple floors and/or other areas may be reviewed in one meeting as appropriate or as agreed to by the parties involved. Development of 3D models will be by area and floor with order of priority established by Leopardo Companies, Inc.

COORDINATION DRAWING PROCESS
A. Two business days prior to each coordination meeting, all subcontractors will forward their completed 3D models for the area under coordination to LCI and the HVAC contractor for compositing. HVAC contractor will composite all other MEP related trades’ drawing/model files from other subcontractors. Subcontractors shall come to meetings with two prints of their work. Subcontractors, at the meeting, will work to review and resolve identified collisions. Following the meeting, Subcontractors shall revise their 3D models, if necessary, based upon the agreed changes and be prepared to meet again within five (5) working days of the first coordination meeting as scheduled by Leopardo Companies, Inc.. B. When the coordination models have been fully revised with no exceptions taken by respective Subcontractors, the Subcontractors shall sign off on them, indicating their awareness of and agreement with the indicated routings, elevations, layouts and their inter-relationship with the adjoining or continuous Work of all Project components. Thereafter, no unauthorized deviations from the information provided will be permitted, and if made without the knowledge or agreement of the Architect and Leopardo Companies, Inc., this unauthorized Work will be subject to removal and correction at no additional cost to the Owner or the Leopardo Companies, Inc.

EXECUTION
END OF SECTION 01365
A. After completion of the final coordination models, minor changes in duct, pipe or conduit routings that do not affect the intended function may be made as required to avoid space conflicts, when mutually agreed to by all parties involved. However, items may not be re-sized or exposed items relocated without Leopardo Companies, Inc.'s written approval. No changes shall be made by Subcontractors in any wall or chase locations, ceiling heights, door swings or locations, windows or other openings, or other features affecting the function or aesthetic effect of the building. If conflicts or interference’s cannot be satisfactorily resolved, Subcontractors shall notify Leopardo Companies, Inc. who will, in turn, obtain a decision from the Architect. B. Record copies of the final project 3D model shall be retained by Leopardo Companies, Inc. and each Subcontractor as a working reference. All shop drawings, prior to their submittal to Leopardo Companies, Inc. shall be compared with the final model and amended accordingly by the Subcontractor responsible. Any revision to the drawings which may become necessary during the progress of the Work shall be noted to and by all Subcontractors and shall be neatly and accurately recorded on the record copies. C. The 3D object models need not be submitted as a whole, but they shall be submitted in all cases per Leopardo Companies, Inc.'s project master construction schedule and in ample time to avoid construction delays. D. No extra compensation will be paid for relocating any duct, pipe, conduit, or other material that has been installed without proper coordination between all Subcontractors involved. If any improperly coordinated Work, or Work installed that is not in accordance with the approved coordination composites, necessitates additional Work by the other Subcontractors, the costs of all such additional Work shall be solely borne by the Subcontractor responsible.
