If location of walls, door bucks, window frames, etc. cannot be guaranteed, the job for the interior stone">stone installation shall be field measured, or certain critical slabs shall be shipped over-sized for field cutting. Exterior stone">stone shall be prefabricated in compliance with approved shop drawings. Perimeter offset lines, column center lines, benchmarks, and other necessary survey marks shall be provided to the stone">stone contractor for the stone">stone layout on each floor. Where possible, cuts or nails shall be provided in the concrete floor rather than paint or crayon marks. All critical phases of the installation procedure shall be performed by qualified mechanics under the supervision of a registered architect, engineer, or consultant, who understands the anticipated mechanical and thermal movements of the supporting structure, the function of the gravity and lateral anchors, and who knows the physical properties of the stone">stone being used. Supervisor shall be able to recognize field conditions which deviate from the specifications and/or shop drawings, and shall make substitutions to meet field conditions or, if necessary, stop installation until acceptable measures or changes may be taken. Close coordination is needed between the General Contractor, the stone">stone Cladding Subcontractor, Architect, Engineer, stone">stone Consultant, and Field supervision personnel to make certain that all components (inserts, gravity, and lateral anchors) are located and installed as designed, within allowable tolerances and that the type and number of anchors used for stone">stone cladding is in strict accodance with the specifications and approved shop drawings. |
