Constructibility refers to ensuring in advance that a building or structure can be built efficiently, in terms of time, resources and money.

Planning and ordering materials with incomplete information will result in mistakes in orders. With BIM Building Information Modeling technology, one or more accurate virtual models of a building are constructed digitally.

No one ever buys anything without considering whether it will be worth trading a certain amount of cash for it. How did Wareing Buildings use a central information management system to digitize their everyday business processes, controlling, tracking and delivering jobs? Benefits of using 3D models are obvious but why are so many people still using paper or 2D drawings? Discover why Tekla's unique technology is Different but Better for Pouring and find out the new pour-related features and improvements available in the newest version of Tekla Structures.

Discover the latest Fit Objects, List Manager, and the Navisworks and Revit Import extensions which will boost your productivity and save your time. One of the hottest trends in the building industry right now is modular or pre-panelized construction.

Three detailing and engineering companies have chosen to stay ahead of the competition by providing software development services besides their Tekla design services. Please tell us something about your background. How did you become an expert in rebar-detailing software? Can you please describe the rebar detailer job and some of its challenges?

There are five key things rebar detailers need to consider when detailing rebars: Bar handling: A rebar starts at 10 millimeters in diameter and goes all the way to 50 millimeters, so you can imagine how heavy a millimeter rebar is when it is about 10 meters in length. The construction team needs to be able to handle the different sized rebar onsite, including taking it off the delivery vehicle and manually moving it into position. The clashes: Those lines might look pretty on paper, but are those bars going to fit in the hole onsite?

Are they clashing with other accessories, such as embeds and bolt locations? The fabrication requirements: Checking fabrication place realities, including space limitations to create different shaped bars, the geographical location of the fabrication shop, and even the resources e. There is a lack of certain information that they require to do their job effectively, and although they cannot interpret the whole job, for those with more experience there is less of a struggle.

Many mistakenly believe that rebar detailers are engineers. There is no formal schooling that one can take or needs to take to become a detailer. A general knowledge of construction, or a diploma in some discipline of construction or architecture, is enough to suffice. This knowledge or degree tends to be enough to land an interview with an employer offering a junior detailing position.

Once hired, the training begins. The important thing to note here is that the clear majority of detailers start their profession with no experience or training in the job at hand. Detailers learn about placement, the common methods of communication in the field, and how to create the drawings for the field personnel.

They can move up the ranks after a few years, with some small to medium projects under their belt, and be considered an intermediate detailer. With six to seven years of experience, and many more projects completed, they could then be considered a senior detailer. Our industry, like any trade position, is facing a worker shortage. As more jobs become digitized, there is less interest in this type of hands-on work.

These companies are finding it difficult to hire a junior and get them trained, without taking a hand away from another job, just to get them up and running.

These omissions may be noticed only after drawings have been issued. And, you might need to do the work again. In a workflow that utilizes 3D tools, all the parties in the project can review the model from early on. Having more eyes on the model will help to spot the missing parts on time and increase collaboration. Besides, with this level of transparency, the constructability of the design, and the entire construction process can quickly be reviewed.

This ensures that every required rebar can be accounted for, and the rebar process fits the whole workflow. In the course of the design process, you may notice that specific details or sections are missing or have changed and should be added.

This can be quite tedious, manual and time-consuming work when doing it in 2D. You might need to track different versions of changes and make new drawings for these extra details.

When using 3D design tools, you can quickly create new sections or views and add them to the 3D model. All the parties in the project can also immediately see and give feedback on the changes.

The drawings are created automatically, so there is no need to create a model and drawings separately. In fact, you can get all your deliverables from the model. Lapping locations are a key point in rebar design. Unfortunately, they might get overlooked in 2D drawings. This means extra work and therefore, more costs.

When using 3D design tools and a constructible model, any congestion or clashes can be easily identified. This is thanks to the preliminary models that can be created at the start of the detailing process, based on the design intent.
