Model For Approval Model for Tender (UoM s not LOD s) Only 1 copy of something to exist if you need it, log it in Revizto If an issue isn t in Revizto it does not exist Model -> Approve -> Site Eng Sign-off -> Setout Document For Setout

13 Client Heavy Visualisation Usage Revizto Reporting Brief Management Revizto is Source Of Truth for Issues/Model Vico/Primvera/Excel is Source Of Truth for QTO, Construction Revit Schedules is Source of Truth for Design

14 Architectural KPF Workflow Rhino Envelope Revit Model (Panelisation) Flux (Outlines) 2D Tieback details Schedule of Panels Façade Consultant & SPYTL Used Revit Model

15 SPYTL Architectural Model Co-Located Design Teams for critical design periods All Teams started in the Architectural Model Structure Model Mech Spaces Elec Components by Space Lighting Components by Space Hyd Fixture Counts

16 ESD Consultant Developed Model in-house to save costs Provided with Parts Based Model Sent multiple iterations Provided Access to Revizto for Documentation & Data.

17 Structural Workflow Arch & Engineers worked together in the same Model Model was split AFTER Tender Arch owned stairs, ramps & all structural elements and would change based on Structural issues or design changes.

18 Electrical Design Lighting & Power provided in Room Schedules as a tag. Allowed fast sizing of panels Layout was done ONCE interiors were approved for Tender

19 Mech & Fire (Webco) SPYTL trained Webco in Revit SPYTL would manage all coordination & would update Webco s Models Webco documented work packages.

20 QS Roadmap Provided Revit Schedules Provided Tender Model (Vico) WIP Models Provided once a week QTO done in Vico (Costing done in excel)

21 Site Implementation Quick Optimisation Checks with Vico Import into Primavera Developed Site Logistics in Revit Maintained & Tracked all Penos
