Rebar Detailing

Rebar detailing services is one of the key as well as the most important services that we offer for a large variety of buildings and facilities of any complexity, providing shop drawings for constructing reinforcement of steel.

BIM Modeling

BIM or Building Information Modeling is the new as well as the latest services of approaching the designs. It is the process where you can convert all your paper design into a digital format.

Structural Analysis

Calculation of joints is the most critical step in detailing, as joints being the weakest link in structures. Thus we offer a professional approach in calculation connections, using special software, such as IDEA StatiCa.

As steel detailers, we generate 2D plans and 3D models to aid the fabrication and erection process of steel framework. These technologies allow us to maintain strong and focused plans/ models for all projects, regrdless of scope and complexity.

Steel structures detailing Steel structures detailing is an essential part of a steel structure design. Manufacturing of steel parts (details) is fulfilled in accordance with detailing drawings. Steel detailing is the production of shop drawings for a steel fabricator.

Advanced Bill of Materials - The preliminary metal specification required for the project.

A Single part drawings - а set of drawings of each part with all the dimensions to produce it. Each drawing consists of one part with all dimensions and other properties. Single-part drawings depict how many parts with this mark are needed and which assemblies include them.

Assembly drawings - display how to weld detail pieces to each other. The drawings show dimensions and general size of each assembly and include bill marks of each detail and marks of assembly.

Bolts specification - the list and number of bolts to be applied in a structure.

Erection drawings - the installation process is held in accordance with these drawings. Erection drawings consist of plans and a section with marks of assemblies. Erection drawings may display typical joints.

Bill of Materials - list of materials required for manufacturing. The material loss incurred in cutting is not considered in this bill. Usually, the loss of cutting is from 1% to 5%.

Shipping List - the list and the number of assembly. Mark (assembly) is a structural element which is sent from a workshop.

    Rebar detailing is a detailed construction engineering process that includes the bending shapes, placement, dimension, quantity, description and laps of the reinforcement. TopEngineer is able to provide rebar detailing for a large variety of buildings and facilities of any complexity (rebar framing plan design, rebar structure foundation, rebar pit design, rebar framing plan, rebar beam design). Today you can find reinforced concrete in nearly every major construction project such as roads, bridges, industrial and commercial building structures, sewer systems, ventilation systems and many more. The primary use of rebar is to reinforce a piece of concrete because of its weak tensile strength. To overcome this, rebar is cast into it to increase its tensile strength, guaranteeing load support and minimizing stress. Here at TopEngineer we offer efficient rebar reinforcement modeling in 3D, producing and achieving high-levels of accuracy. Working with Tekla Structures software allows our engineers to draw precise and accurate 3D rebar detailing, which is easier to interpret and faster to detail than creating a 2D drawing. In addition to the drawings, we provide CNC machine data which helps to cut and bend the rebar to the desired shapes.

    Our skilled staff provide high quality detailing and optimal model calculations including estimating the efficient amount of rebar and concrete needed, minimizing costs and saving time.

    Bar bending schedule(BBS) - describes the location, mark, type, size, length and number, and bending details of each bar.

    Placing & shop drawings - provide instructions to the field ironworker on where to place the reinforcing bars within the form work. Placing drawings may also indicate the bar support layout and a placing sequence, facilitating the efficient installation of the reinforcing bars.

    As built drawings - the original design drawings are revised to reflect any changes made in the field.



    BIM is a universal platform for building. It puts together every piece of information about every component of a building project. With BIM you are able to access any type of information, integrating everyone working with the project, making everything more efficient and cost effective. Companies using BIM save production costs and time as they have a much lower chance of making mistakes.

    The data from BIM about any given building can be used to simulate the full life-cycle of a facility, from the beginning of initial project production until the demolition phases, counting in the recovery of any recyclable materials. Subsurface and below-ground spaces and facilities with their systems can be modeled and shown using a 1-to-1 scale next to each other, which in turn can be simulated and depicted in the entire project. Such vast amounts of information can prevent any errors which can show up during different phases of the project.

    Usually, the calculation of connection in a steel structure is needed to develop steel structures detailing design. Construction calculations are necessary to select the best matches and optimal connection configurations while using the minimum of material consumption. A detailed study of the calculation of all the project components can greatly increase the complexity of the final project and increase the time and cost of design.

    The result of joint calculation is to be presented in the form of a calculation note. In order to calculate joints in steel structures, the actual loads acting on each element are needed. If the actual loads cannot be highlighted in the basic design of steel structures, it can instead be developed beforehand.

    If connection calculation is necessary, we use IDEA StatiCa, a program based on the method of finite elements used to calculated connections. IDEA StatiCa allows us to calculate steel joints such as 2D frames and trusses, footing and anchoring, 3D frames and trusses and reinforcement connections such as beam details, wall details, diaphragms, frame joints, hangings and brackets. The price evaluation for each project is bespoke and there are a few factors influencing the cost.
