BIM-Landscape-Architecture-DataMany landscape architects get hung up on the concept of BIM (Building Information Modeling), simply because it contains the word ‘building’. But BIM is really just the next technological progression in the AEC industry. It is a shift from creating printed drawings of the landscape, to creating and coordinating data within a digital model of the landscape. In some ways, the switch to BIM is perhaps more difficult than the switch to CAD because it requires a substantial change in the processes that have been in place since hand drafting.

Somewhere along the progression of CAD to BIM, there is an in-between phase of more basic 3d modeling, where you can find computer programs like SketchUp, Rhino, and 3ds Max. Programs like these allow you to create digital 3d models, but these models have almost no information in them and, as a result, are fairly limited in their use. These models are great for design visualization, but they do not allow for for scheduling of quantities or materials. And these programs do not facilitate the creation of construction documents from the model nor allow for coordination between models.

Thus, the critical difference between basic 3d modeling and BIM is the information (or data) within the model. The idea being that every object in the model has data that is pertinent to that object. For example, a tree within a BIM landscape would have the parameters necessary to install the tree, such as its scientific name, root size, condition, and install height. It could also have relevant design information such as the mature height, spread, water and sun requirements, and bloom time.

Having this information in the model allows for quantity scheduling, material takeoffs, model coordination, and also automates the documentation process. As a designer, the information in the model can also start to drive critical design decisions, such as how to best capture and store rainwater. Once the project goes into bidding and construction, the BIM process allows for more accurate cost estimates and scheduling, reduces design errors and changes on-site, and facilitates a more coordinated construction and delivery process.

CAD-BIM-Landscape-Architecture-DataSo the benefits of the BIM process can be distilled into a single concept: it is more efficient, and thus saves money. And money is a powerful motivator, so it is no surprise that architects, contractors, and even clients are all moving to adopt and even require BIM on their projects.

For landscape architects, this shift to BIM can be a bit unnerving. It is quickly becoming the industry standard and in the UK there is now a BIM mandate on all public sector projects. However, while it is relatively easy for architects and building engineers to transition from CAD to BIM, there remains a software gap once you move out into the landscape.

So as a landscape architect, what are the options if you want to move from CAD to BIM? Unfortunately there is no magic bullet, no perfect program, and the answer will vary depending on the project and project team. This wide array of answers is due to several factors: first, landscape architecture is a very broad field and projects can vary widely in size, scope, and detail. In addition, landscape architecture is a relatively small discipline, especially when compared to architecture or even civil engineering. And as a result, there are far fewer programs that will cater specifically to our needs.

The graph below maps some of the most commonly used landscape architectural software. Along the x-axis, each software was given a BIM ranking, determined by its parametric 3D modeling and database capabilities, while its placement along the y-axis was determined by the discipline-specific features available within the software (ranging from architectural to more civil engineering).

Starting at the CAD end of the spectrum, Microstation and Civil 3D are definitely more civil and infrastructure focused. And though these programs have extensive 3D modeling capabilities, their parametric and database capabilities are quite lacking, so they scored low on the BIM ranking. In the middle of the graph, there are some landscape architectural-focused plug-ins that give BIM-like capabilities to more basic modeling programs. Lands Design is a plugin for Rhino and Land F/X is an add-on for SketchUp (and AutoCAD). Both of these programs have specific tools and databases for planting, irrigation, and site furniture, however those databases are limited and they do not have full parametric modeling capabilities.

Finally, in the upper right corner are the most fully integrated BIM programs: Vectorworks, ArchiCAD, and Revit. Of these three, only Vectorworks offers a package specifically for landscape architects (Vectorworks Landmark). However, it is worth noting that Revit is the market leader among these options, particularly in the United States and Australia. And even though some people think that “Revit is not a viable landscape architecture solution, ” more and more landscape architects are using Revit to deliver landscape BIM projects.

Landscaping Tips

Though your home is your castle, there is no necessity to surround it with a moat. Here are 5 tips that will help you to make your landscaping feel more warm, welcoming and cozy.

1. Put some flowers nearby your entrance. Flowers make any area look more welcoming and attractive, so greeting your guests with Petunia, Snapdragon, Lily-of-the-Nile or some other garden flowers is always a great thing to do. What is more, to add some space between your house and the entrance, you can consider adding a little white fence. It will create an illusion that your front yard is bigger than it actually is. What is more, adding fence will create a great space for planting flowers to add some color and coziness.

2. Add rambling vines to make your yard look absolutely lovely. You can not deny that rambling vines always create romantic and even magical atmosphere. So why not to use this tip while decorating your yard?

3. To hide the unattractive driveway, consider adding some color, texture, and height. You can easily do it by adding various sorts of flowers. To start, create an island of green lawn right in the hub of a drive. Then add a couple of low boxwood hedges with flowers toward the back of your island.

4. If you want your yard to blossom and flourish bust still do not have enough time to maintain it, consider planting low-fuss lilies. Such flowers look absolutely gorgeous and come in the variety of rainbow hues, so you can pick the one you love most. What is more, low-fuss lilies do not care about the sort of soil, they love the sun and welcome hot, they do not afraid of drought. In other words, Crinums is an ideal flower for all those who are looking for low-maintenance solutions.

5. The last tip also touches the low-maintenance aspect. To make your life easier, group plantings into beds and islands. This will help you to avoid mowing and trimming around each individual plant, save a lot of time and even money.
