Architectural Revit SEED Process for establishing origins with consultants

The 'seed' process requires Architecture to create a base minimum shell model of slab, grids & floor levels for each building. These seeds are distributed to the consultants to ensure each trade within a building links to the same coordinate system.
Sample seeding process:
·         Architectural creates a shell model of slab, grids & floor levels for the buildings- establishing the XYZ 0,0,0 point- typically at a grid intersection (A1)
o    If a good CAD File has been created and can be used they should be brought in at 0,0,0 and followed as a basis of organization so CAD and Revit will overlay properly
o    If no reliable CAD files exist origins can be located by turning on the "Reveal Hidden Elements" light bulb located at the bottom-left of the modeling view
·         Enables work sharing
·         Saves the file with correct naming (per project requirements)
·         Depending on which is the most logical discipline to control the grids & levels:
o   If Architectural is charged with controlling the model- structural references/copy/monitors the Architectural model.
o   If Structural is charged with controlling the model(need more immediate access for structural analysis, etc.):
§  Architectural sends the seed to structural.
§  Structural takes over the Grids, Levels, Columns and structural walls in their model.
§  Structural sends the model back to architectural.
§  Architectural removes the temporary structural grids from the architectural model- Links structural in & uses their grids & Levels. As a precaution – a copy/monitor operation is typically used so if the structural team should lag behind- architectural can update the model's structural components.
·         Once established the 'seed' model is sent to the remaining consultants.
·         The consultants then copy/monitor the levels and if necessary the grids, walls, floors from structural or architectural.
·         An 'architectural' Revit site plan will be used to locate all buildings on the site.
·         'Progress model' Exchanges are made on a weekly basis at the end of the week(Friday-Sunday)  so that disciplines are always within 1 week of one another. These are not finished products. These can also be made 'on demand' as necessary.
·         'progress models' are copied to archive folders on upload or download for future reference.
·         Alternatives like the riverbed appliance or script automation could keep files updated on an hourly or semi daily or daily basis.
