Structural Steel Detailing

Precision, predictability, and buildability underpin everything we deliver. From first concept to erection on site, our team integrates design intent with constructability to reduce RFIs, compress schedules, and minimize rework.

Designs Mosaic (DM) offer structural steel detailing and design services, including approval drawings, CAD drafts, fabrication drawings, and 3D models. DM has worked with architectural, construction and structural engineering companies worldwide to ease workload commitments and provide specialist technical skills that are not available in-house. DM engineers are trained in a wide range of structural engineering and detailing tools including AutoCAD, Advance Steel, Tekla Structures, ProSteel, etc.

Our 3D-first approach is anchored by structural steel modelling services that translate design intent into clash-free, fabrication-ready models. This enables early coordination with architects, MEP, and site teams, accelerating decisions and improving delivery confidence.

DM offers a complete range of precise structural steel detailing services, which includes estimates, schedules and plans. Our structural steel drawings include information about all steel structural elements such as columns, beams, joists, trusses, braces, etc. Steel reinforcement such as concrete rebar can also be designed. Contact DM to find out more about their outsourced structural steel detailing services.

In addition to modeling and detailing, we provide end‑to‑end documentation and compliance support—so your submittals move through approval with fewer revisions and faster turnaround.

Structural Steel Detailing Services by Designs Mosaic

Every deliverable is tailored to your project phase—concept, IFC, shop, or as‑built—and packaged to fit your workflows and review processes.

The structural engineering team at DM has the knowledge and skills to produce designs, drawings, and reports that comply with international and local standards, such as AISC, NISD, Euro Codes, and British Standards. Here are some of the services available:

We maintain a robust QA/QC process with multi‑stage checks, discipline coordination, and standards alignment—reducing downstream change orders and field queries.

General Structural Steel Detailing

As part of our structural steel detailing service, the drawings and documents include drawing register, cutting list, shop and field bolt summaries, bolt location list, fitting and erection drawings, etc.

3D Steel Modeling and 3D BIM Erection Drawings

DM applies the latest 3D modeling and BIM software to create highly detailed and accurate 3D designs. The 3D and BIM models include all the information needed for site construction. Our structural steel modelling services support federated BIM workflows, clash detection, and coordinated erection strategies—improving safety, access, and crane planning.

Framing Plans

Plans and drawings that include all the structural elements to create a steel framework. Frameworks can be designed from scratch to suit your specifications or templates used to speed up the process. We optimize layouts for fabrication efficiency and site productivity, balancing member counts, splice locations, and transport constraints.

Steel Connection Design

The engineering team at Designs Mosaic provides detailed drawings of steel connections, fittings, and fixtures. Information on how the connections are formed, the welding, bolting, etc. are all included. Connections are engineered to code and constructability, with clear tolerances, weld symbols, and coordinated hole patterns to reduce shop errors.

Shop Fabrication Drawings

DM produces detailed drawings that are shop-ready and can be fabricated right away. The steel members or elements that need to be fabricated are drawn individually with all the dimensions, locations, etc. clearly displayed. We streamline submittals and revisions through our structural steel drafting services, delivering unambiguous shop drawings, CNC‑ready data, and clearly marked revisions for rapid approval.

Bill of Materials (BOM)

A comprehensive Bill of Materials can be provided alongside any structural steel drawing or design, with quantities and costings included. Material lists are structured to align with your procurement process—by assembly, sequence, or lot—supporting accurate ordering and tracking.

Anchor Bolt Plans

Plans of anchor bolt locations for ground fixings and attachment of steel elements to concrete. Drawings and plans also include details such as bolt sizes, thread sizes, required tensile strength, and torque settings. Clear setting‑out reduces site rework and accelerates slab pours and baseplate installation.

Steel Estimation Reports

DM develops steel estimation reports that include quantities of steel used and approximate costings. These can be included with designs and 3D models or produced independently if required. Early estimates help you benchmark options, evaluate alternates, and control budget risk before committing to fabrication.

Embedded Material Plans

Embedded material plans are mostly produced for steel-reinforced concrete. Rebar sizes, shapes and layout are included, as well as concrete depths and any beam or column sizes, etc. Rebar and embed coordination is managed in 3D to minimize congestion and ensure pour sequence continuity.
