CHARTERED BUILDING SURVEYORS
Peter Napier and Co
Until 2007 all drawing work in this office was undertaken using 2D Autocad LT. Until then 3D modelling was not thought to be necessary. However, it was decided to upgrade to a CAD package that could provide 3D images mainly to help clients to visualise our proposals.
We spent 12 months looking at various alternatives and in the end we chose Autodesk® Revit® Architecture building design software. We purchased this from Cadspec whose after sales support has proven to be the key to upskilling in an almost vertical learning curve. Cadspec offer excellent training to allow swift conversion to Revit.
Revit has proven to be almost limitless in what it can provide. All design work is carried out as a 3D parametric model which means that sections can be taken anywhere and all the elements of structure at that position will appear in that section.
Internal and external 3D views can be generated and if necessary these can be rendered to provide an almost lifelike view. Walk throughs can also be generated although these take a lot of rendering time and so they are usually kept to a minimum.
All manner of information can be scheduled provided that the information has been built in - doors, windows, walls, finishes, manholes, desks, lighting, wall types, rood types, materials, quantities etc.
Because the model is in three dimensions, it is easy to locate ducts, services and structural elements such as steel frames, structural floors etc.
Revit has a suite of CAD software for structural engineers and mechanical and electrical services engineers. With these all members of the design team can integrate their information packages using a single model ( see under BIM ).
Cadspec chose to look at Peter Napier and Co. as a case study because we have been using Revit in our historic building projects as well as all new build.
