The CAD hangover vs BIM karma

I'm quite lucky really... I work in a highly creative environment, with thought leaders, technical innovators and have a boss who really understands BIM, whilst allowing me the freedom to look at how we can do it better.

BIM implementation is largely a cultural thing in my opinion - back in the "good ol CAD drafting days" people focused exclusively on the plan, detail or section they were producing that day. BIM karma forces us to consider how we build it and what the guy sat nextdoor is working on tomorrow?

In the "flatland" 2D CAD days, we documented things in a prosaic, manually intensive way, trying desperately to coordinate drawings, packages - invariably with little recognition from clients of the effort required to make this happen.

In 2012, we have the tools available to automate these historic pipe dreams and get technology to work for us... for a change. Some of these tools have been around for a while, but generally by exception rather than as a rule.

CodeBook is a highly detailed program and when combined with Revit it can provide miraculous results - BUT - there are some basics that are often overlooked in the new world of BIM complexity.

Understanding what information you already have available to you, not re-inventing the wheel and making the most of that data is regularly forgotten when creating deliverables and "getting drawings out."

I'm an ardent believer in NOT duplicating information, but knowing how to extract and how to make the best use of the data available, in the right medium, is a skill that often comes with a high premium.

Going back to grass roots, reminding you of what you may already know and the information already available to you is the purpose of this "serendipity-esq" post.

Room information and room data stored within your CodeBook database is ready and waiting for you to utilisse within the CodeBook Reports. Most people know what is contained within a Room Data Sheet, but may not realise that this information can be pushed into your BIM model, or extracted through a report.

A room data sheet typically consists of:
_design data - the function of the room, the occupancy, hours of operation etc...
_finishes - floor, wall, ceiling, doors, internal glazing etc...
_environmental conditions - temperature, HVAC, hepa filtration, lighting lux levels, UPS, etc...
_equipment - furniture, equipment and services

...and whilst we report these conclusively in a Room Data Sheet, they can be extracted individually for architectural reasons and to aid in coordination with other disciplines.

The CodeBook reporting function has a number of pre-defined reports, but also several that can be configured or customised to provide whatever you may need through the report settings.

For example, if you wanted to extract the acoustic data, floor finishes, or lighting lux levels to send to a consultant for coordination - you can create a Room Data (xls) report specific to that data.

The way you do this is to select a Room Data (xls) report and in the report settings pick (through tick boxes) the information you require. These are categorised in sections - Room Information, Design, Finishes, Equipment and M+E - first you choose which section you require and then select the fields within these Categories that you wish to report.

For example = choose the Design section and tick the box for Occupancy - CodeBook will produce a report restricted to that information, which can then be emailed to the Services Engineer for checking.

An alternative to excel is to map this data in CodeBook to a corresponding Revit Room Parameter and provide the Services Engineer with a colour scheme drawing that shows each rooms Occupancy values by colour.

In practice you may wish to choose more data than this to send to your services consultant, but individual parameters may be useful, especially when represented in the context of the building through a colour themed view.

The "BIM karma" mentality involves recording information correctly once and then utilising it many scenarios.

Make it happen.

  1. Is there a free website to learn CAD Software, eg Pro/E, Unigraphics or Solidworks?
