INDBIM offers high quality structural steel detailing services.

Steel framed buildings have progressed urban architecture with the ability to build taller and stronger structures with predictable load shedding capacity. Even though these building may have a small footprint, it is often thousands of steel beams, shapes, plates, fasteners, and prefabricated assemblies that must be precisely detailed for shop machining and accurately marked for erection sequencing.

Steel structures that are modeled with the Tekla Structures BIM software are not only more accurate, they also carry more detailed and reliable information about each framing component. The result is the ability to create fabrication drawings faster and with less scrap during machining. Overall, the marriage between BIM and fabrication drawings will allow for a smoother erection process – and this is where the time, manpower, and cost savings are realized. Tekla-modeled structures can interface directly with many electronic-controlled shop machines, sending design information directly to CNC routing, laser cutting, or robotic welding workflows.

Revit produces precisely detailed pre-cast concrete shop drawings that can be referenced by all stakeholders, including concrete suppliers and field rebar installers. Pitfalls when fabricating pre-cast concrete structures are avoided, saving time and money from wasted efforts. Not only is the pre-cast concrete workflow verified against the architectural documentation, all quantities and concrete mixture variables are included for faster on the job installations.

An entire library of predefined rebar shapes are available to make reinforced concrete layouts and fabrications proceed quickly. Reinforcement tools allow designers to quickly add rebar, anchors, hooks, and other reinforcing elements to columns, concrete beams, foundations, and structural floors. The automation of rebar numbering for schedules and annotations adds to a reduction in the time it takes to create pre-cast concrete shop drawings.

We will create all the necessary information for concrete lift drawings for deep or shallow foundations, retaining walls, floor slabs and more – by automatically pulling the information from the 3D model. Any additional footing or splicing components are also created for a complete set of concrete assembly drawings, including accurate quantity take-offs. At INDBIM, our team of BIM specialists and structural design experts work to make sure structural shop drawing information is not missing that can result in costly mistakes such as incorrect sequencing or missing embeds. And when accurate cuts and sections are taken directly from the model and integrated in the shop drawing set, field workers can better visualize the end results that are expected. And this reduces field conflicts that were missed in the design process due to human error.

Structural steel shop drawings

Pre-fabricated steel components created from accurate structural steel fabrication shop drawings are key to ensuring efficient and high-quality erection of structures at the construction site. It is this precise, off-site fabrication of thousands of pieces of steel components which creates a competitive advantage of steel construction over concrete buildings. The use of construction-site fabrication of steel members has long been deemed as producing inferior quality workmanship, as the many operations from surface cleaning, machining, fitting, and finishing lack the controlled environment of fabricators that use shop drawings to create steel assemblies with tight tolerance and quality assurance standards.

For these reasons and many others, owners and stakeholders agree that structural steel detailing offers competitive project advantages from design and construction to safety and maintenance. Central to the entire building process is the structural steel fabricator. These shops play an imperative role in the steel supply chain, using advanced CNC machinery and material handling equipment to consistently produce a high-quality product in a controlled environment from accurate steel shop drawings.

A&E firms will generally outsource the production of these shop drawings to services which employ skilled structural steel detailers to ensure the structural steel engineer’s intentions are reduced to manageable pieces for fabrication and transportation, incorporating detailed symbology with accurate tolerances, and consistently marked pieces for seamless and sequential erection procedures.

Structural steel models shared as a Tekla Structure will provide valuable input into fabrication drawing approval process because it will utilize the precise 3D model geometry and underlying engineering data to generate the additional views and information needed for structural steel fabrication shop drawings, such as connection size, type, and spacings, type and quantity of welds and bolts, and the dimensions and grade of connection plates.

Critical Role of the Structural Steel Detailer

Bridging the gap from design to erection lies the crucial role of the structural steel detailer in creating the structural steel fabrication drawings needed for building erection. To achieve the level of detail steel shop drawings require, a steel detailer must be educated in structural steel design and drafting, and have keen industry knowledge of machining processes and construction practices.

Establishing an outsourced partnership with INDBIM service will give A&E firms a cost-effective solution for fast drawing turn-around and assurance these drawings are constructed under the approval of certified engineers and experienced steel detailers. From 3D model to detailed shop drawings our technicians are trained to produce an accurate set of structural steel fabrication drawings that comply with the structural steel design. Our engineering shop drawings will ensure fabricators use the proper grade and strength of steel, and will aide the erection process by detailing the requirements for lifting and locating each piece, emphasize structurally critical dimensions, and specify the locations of bracing and temporary supports.

Trust our firm which has completed all manner of steel construction shop drawings for many different types of  projects, both large and small – from connection details to fabrication shop drawings and erection drawings and steel detail drawings.

Rebar shop drawings

When you are in need of rebar shop drawings, there are several important things you will need to know. This will ensure you are able to obtain high-quality drawings that are as detailed as you need them to be. This will simplify the construction project and eliminate any questions in terms of design along the way.

2D and 3D Drawings are Available
You will need to decide whether you want the drawings to be in 2D or 3D. Both have advantages and disadvantages, and it will be dependent upon what you are using the drawings for. It may be advantageous to start with 3D so that it can provide a more detailed concept. You can also use 2D To 3D drawing conversion services

Reports Can Be Comprehensive
You have the opportunity to obtain printed reports within the drawings that will provide details about the schedule as well as the bar weight. This can be a game changer when it comes to your project management.

Get the Annotations
When contractors are working from drawings, they may have questions from time to time. You can opt for annotations that tag various objects to ensure that there is no guess work happening.
