Building Information Modelling BIM

 

Introduction:

BIM stands for Building Information Model. A lot of architects use the term to refer to 3D software, but this is just part of BIM. It is also about managing the information contained within every project, and improving design and collaboration.

We have been committed to BIM for a long time. In fact way back in 1998 we started working on our first BIM projects. Back then architects using Microstation talked about ‘Integrated Project Models’ and ArchiCAD users thought of the ‘Virtual Building’. Most architects had only just come off the drawing boards and started to use 2D CAD. According to the National Building Specification NBS BIM report data in 2002 only 13% of architects used BIM, rising to 47% in 2010 – so it has taken a long time for BIM to make it to the average architect’s practice, and 2PM Architects has always been ahead of the curve, and in this post we will explain some of the benefits and why we use it.

Building Information Modelling BIM

Some Reasons We Use BIM:

The first step in designing and planning a rural home under Paragraph 80 is to conduct a thorough site analysis. This involves assessing the site’s location, topography, orientation, and ecological value. The site analysis will help you to understand the constraints and opportunities of the site and inform the design process.

 

1. BIM Is Great For Concept Design

Sketches on the back of a napkin are OK. But not if you’ve sketched the site to the wrong scale or got the size of the building wrong. That is why we bring our sketches into BIM, and it’s really easy. We often just snap a pic of the sketch on our phone and save it to a Dropbox app. Then we grab the sketch, set up a worksheet in BIM and overlay the sketch on accurate site data. Just to check, and because it’s nice for our clients to know that our concept design ideas and feasibility studies are accurate and will work.

 

2. Using BIM Means Clients Get 3D

Using BIM means we can give all our clients a 3D model that they can open on their phone, tablet or computer. We share the 3D file with our clients in a Dropbox folder, and then all our client needs to do is download a free BIM app and they can open up their project and explore. We keep the BIMx file updated with any design changes, and our clients get to see their designs in 3D any time they like. 2D drawings in the BIMx are linked to the model, so you can cut and move a section, elevation or plan in real-time. Clients who enjoy the tech can even press one button and turn the project to VR, place their phone into a free VR headset and walk around the design.

3. BIM Helps Keep Track Of Design Ideas

There are always a lot of ideas bouncing around at the early design stages, including things we talk about at design meetings, and stuff which our clients might have emailed to us or pinned online for us to see what they like. We compile all of these ideas and use our BIM project folder as a shared space that we keep up to date with our clients. Then we overlay the information from this folder with our BIM model, so for example, if we are designing a bathroom we will set up a worksheet in our BIM software that contains overlays of the sanitary products that our client likes. It might seem simple, but in 2D CAD changes can quickly become hard to manage among the mass of drawings and files. It is better to use a single BIM file and a clear shared folder.

4. Design Changes Are Faster With BIM

There are some design changes on every project. It’s just part of the iterative design process. But BIM helps us make these changes quickly. For example, if our client decides to make some changes to the design. In the old days updating all the drawings individually would take a long time. But in BIM we make the changes to the 3D model once and then simply regenerate all of the drawings. So we can send new drawings to our client much faster. When the change is approved we update the drawing revisions in the BIM folder so everyone has up-to-date information.

5. BIM Allows Coordinated Teamwork

As architects part of our job is to lead the design team so that everyone works together well. Using BIM software we can work across teamwork servers which means everyone involved in the project can actually work on a shared BIM model at the same time. Or if using a shared server is impractical, for example on small projects where the only other consultant involved is a structural engineer, then we can share a simplified BIM model with the engineer by email or Dropbox. This makes it much easier to handle at their end, and can easily output to 2D drawings. We then X-ref the engineer’s info and update the BIM model with their structural design work to make sure everything is coordinated.

6. Higher Quality Drawings And Information

The speed and efficiency that we get from working in BIM means that each of our projects can benefit from more time to develop the design, more freedom to make changes quickly, consistent information with fewer mistakes on site, buildings delivered sooner, and costs kept down. These are really significant benefits that add up to a better quality of project. This is why the UK Government require BIM level 2 on all public sector projects. But private clients and homeowners should equally demand and require BIM to deliver better quality projects for them too.

 

7. Access The BIM Model Anywhere

Being able to pick up a phone or tablet wherever we are and access any of our drawings is great. We can also check any part of the specification and even get the 3D model open. This is fantastic on site when checking a detail; great when meeting a new client and showing them what we can do; and pretty good in the pub to show off the portfolio (we don’t do that!). The whole concept of BIM and the idea of organising the information in a way that is accessible and provides the right information for each project depends on setting up this shared space so every file is in sync on every device. Our BIM software will then publish all of the drawings to the right folder automatically, so they are always easily to find.
