2 INTRODUCTION: The Project: The Scope of Work: The Process: Challenges/ Benefits: Questions

3 The Project:New Asda Store - 40,000 Sq. Ft

4 Scope of Works: Design and Install New Fire Sprinkler System. 40,000 Sq. Ft New Store. The store sits above the Car Parking which is below. The Store has a Storage Tank and Electric and Diesel Fire Pumps. Asda required the design to be carried out using “Revit” / Autodesk) software. There are 4 Levels of “Bim” This project was Level 2. “COBie” was not requested.

5 The Process: 1 The design process involved the different disciplines Architectural. Structural. Mechanical, Electrical, Plumbing (MEP) Refrigeration. Fire Protection. Uploading their “Revit” models onto “Autodesk Buzzsaw”. From Buzzsaw we downloaded their models onto our company server. The Revit models are large files for example the Architectural = 113mb So you need plenty of hard disc space for this process. We use an add on software called “Hydracad” that while it uses the Autodesk platform, allows us to design the Fire Sprinkler system more efficiently. Our Scope of Works Design and Install New Fire Sprinkler System The Customers Requirments Asda required the design to be carried out using “Revit” Software Used in the process The design process involved the different disciplines (architectural/structural/mechanical/electrical/refrigeration) uploading their “Revit” models onto Autodesk Buzzsaw. From this I downloaded there models onto our server (the Revit models are large files for example the architectural 113mb), I opened the models and export the different plan view and section into AutoCAD 2D drawings to allow us to use Hydratec. export the different plan view and section into AutoCAD 2D drawings

6 The Process: 2 The conversion of the “ Revit “ files while using “ Hydracad” go to AutoCAD 2D Drawing format. During the design process, in “Hydracad”, we assign certain attributes to the pipework/fitting/sprinklers etc., Once this is completed we can then convert the drawing into AutoCAD 3D model and then generate a “ Revit” 3D MEP File. A New File has to be set up in Revit to link in all the disciplines, including plan views, and sections. Once the new file is set up, and the Hydracad/Revit 3D content is installed in the file, then adjustments can be made to suit coordination and clash issues. This process adds extra design time, previously the drawings would have been received from the client in an Autocad 2d format. By the time you download the large revit files and convert to 2d you have eaten into several days of your design time/budget. Now that we have a 2d autocad drawing to work from, we design our sprinkler system as we normally would on a 2d basis using Hydracad (an autocad based, sprinkler specific design package). This information can be converted into an autocad 3d model easily by using the hydratec tool bars. Now that we have a 3d model in cad we can export this into revit using the hydracad collaborate toolbar to generate Revit MEP content.

7 The Coordination/Clash process: Conducted by the CDM coordinator who used “Navisworks” for clash detection. Clash detection and Coordination issues are then sent back to us in the form of a Clash Report. We use the interference check in “ Revit” to verify the clash.

8 Challenges/Benefits: Challenges: Training in the use of this software and understanding of the process is critical. A clear and concise plan must be communicated to all stakeholders who are involved in the process, and everybody must be on board. One break in the link can cause all sorts of delays and errors. Using BIM adds 30-40% additional cost to the design process.

9 The Benefits: Better collaboration at the MEP Level. Reduction in RFI ( Request for information) Better Sub Contractor efficiency Less rework and expensive changes More accurate and timely as installed information.
