Engineering Outsourcing Services

CAD services for structural engineers provided by experienced CAD specialists like The AEC Associates play a vital role in the design, analysis, and documentation of building structures, as well as ensuring the efficiency, safety, and viability of building projects of all types in the year 2023, and beyond. Computer-Aided Design (CAD) is a powerful tool that enables structural engineers to create precise and detailed digital representations of their designs. There is often a misconception that the use of CAD software is limited mainly to architecture, manufacturing, graphic design, animation illustration, fashion design, etc. However, the significance of CAD services for structural engineers can certainly be maintained in an era when structures are getting more and more complex with each passing day. With CAD, structural engineers can efficiently develop and communicate their structural concepts, produce accurate construction drawings, and streamline the overall engineering process.

6 Ways CAD Services For Structural Engineers Help Navigate Complex Projects In 2023

Importance of CAD for Structural Engineers

CAD design and drafting have become an integral part of structural engineering services. Structural CAD drafting has gradually replaced the erstwhile manual process making it much faster and more accurate. Engineers initially lay out the first set of drawings as per the architectural planning and then the team of drafters details them out with all the parameters.

Structural drafting services adopt a process that involves carrying out one or more of the following functions using the latest CAD software:

  • Drawings for foundation plan and footing
  • Bar bending schedule for Rebar
  • Drawings involving detailing of stairs, handrails
  • Detailing of Slabs, roof truss, and joints
  • Drawings for prestressed components

CAD can be leveraged in the following ways by structural engineers for optimum performance-

  • Design Development: CAD allows structural engineers to create and modify structural designs digitally, making it easier to explore different options, analyze load-bearing capacities, and optimize the structural system for efficiency and safety.
  • Detailing and Documentation: CAD services enable the generation of precise construction drawings and detailing for structural elements. These drawings include plans, elevations, sections, and schedules, providing crucial information for contractors, fabricators, and construction teams.
  • Collaboration and Coordination: CAD facilitates seamless collaboration among project stakeholders, including architects, MEP engineers, and contractors. By using a common digital platform, structural engineers can exchange design information, coordinate with other disciplines, and resolve conflicts or clashes in the building model.
  • Structural Analysis Integration: CAD software (AutoCAD) often integrates with structural analysis tools, enabling engineers to perform structural calculations and simulations. This integration ensures that the design aligns with safety codes and regulations, while also allowing engineers to assess the behavior and performance of the structure under various loads and conditions.

Benefits of CAD services for structural engineers:

  • Unparalleled accuracy

Structural CAD drafting ensures precision and accuracy in details and dimensions when preparing the construction documentation. The result is a flawless execution of the project since there is no scope for any errors/ omissions in these drawings.  Structural engineers are able to deal with multi-floor designs and complex structures easily and effectively using CAD to make sure the design is viable and practical.

  • Improved 3D visualization

CAD software creates 3D models that allow for effective visualization. The results are exceptional and it also saves a lot of time and effort. You can also use these models to convey the design intent to the clients and take their feedback. A better client interface helps you take early approvals and decisions.

  • Convenient data storage

Storage and retrieval of drawings and documents has always been a headache for AEC professionals including structural engineers, requiring a lot of space and effort. CAD, being computer software, solves this issue by allowing storage on the computer server. This offers better access to all stakeholders and is also environment-friendly saving paper.

  • Minimizing rework and revisions

Complex structural drawings are always likely to require changes/ modifications, and the manual drafting process also contained many errors. CAD software creates very accurate drawings with a minimum of errors. In addition, revisions and rework become easier and faster due to some powerful features available. Any change would automatically reflect across all related drawings saving a lot of time and effort.

  • Faster turnaround time

CAD makes the design and drafting much faster and more efficient than the manual process. Modifications made in one part can be penetrated into other parts of the model. For example, if there is some error/ proposed modification in one part of steel fabrication drawings, you don’t have to erase and draw the entire drawing again now. CAD ensures the changes are reflected across the entire set with just a mouse click. Structural engineers are thus able to stick to defined timelines and ensure faster turn-around time every time. 

  • Additional benefits

There are benefits galore of using structural drafting services that may be summarized as follows:

  • Ordinary design drawings from jpg, pdf, png, and so on can be converted to CAD files
  • The generation of drafting documents is simplified for structural engineers
  • Modifications are possible in existing designs too
  • Can generate bills of materials in a better way, saving extra expenses
  • Easy sharing and transferring of information between team members
  • Better coordination with architectural, MEP, and other stakeholders


Hiring CAD services for structural engineers will help you make your buildings safer and more efficient besides ensuring better collaboration with other services like architecture, interior designing, MEP, and FP. CAD makes the design and drafting process more accurate and efficient, faster, and less error-prone for faultless execution of the construction project.

The last decade has seen an increase in the Outsourcing of Engineering Services. An Engineering Outsourcing Services Firm provides Design Support for the building engineering services that go into designing an interior, a building or planning a city.

The Engineering Outsourcing Services Firm could be specialized in any field of Building Engineering: Structural Design, Mechanical Engineering, Electrical Engineering or Public Health Engineering (also known as Plumbing and Sanitation)

This article looks takes a look at the Scope of Services for these firms.

CAD Documentation

Once the shape, material and specifications have been finalized by the design team, drafting becomes a pretty straightforward activity. At the same time, CAD Documentation for Building Engineering Services is quite voluminous. The simplicity, the (implied) monotony, the volumes and the (resultant) checking make Outsourcing CAD Documentation easy as well as necessary. That explains the explosion in Engineering Outsourcing Services Firms over the last decade.


BIM, a parametric CAD program that is transforming the AEC Industry, currently sells as a concept mostly because of its ‘clash detection’ capability. A building drawn (or modeled) in BIM software is able to visually show clashes between different engineering elements of the proposed building, e.g. beams, fire pipes, HVAC ducts, plumbing, wiring trenches, etc. Traditionally, such clashes, despite the best efforts of the best experts, have caused grief and loss to many building projects. Since BIM expertise is not yet widespread, modeling is again a popular scope of Engineering Outsourcing Services.

Coordinated Service Drawings

At an advanced stage of Engineering Outsourcing Services, the scope may also include coordinating inputs from various service consultants into a single Coordinated Services Plan. This normally indicates a high level of trust in the Engineering Outsourcing Services Firm, which would have come from

(a)    Good work done with this client in the past

(b)   Good track record of such services with other clients and similar projects

Material Take-offs

Calculating quantities of materials is also a very ‘Outsourcable’ activity. Currently most drawing software make such counting easy to do, and, for the client, easy to cross-check. The important points to be taken care of by the Engineering Outsourcing Services Firm are:

  • Compatibility: to the program in which the Quantities are to be recorded like Excel, Word or a customized program. Simply speaking, if the Quantities are to be used in a Excel file, then they should be entered as numbers, not as text
  • Live link: Ability of the program to handle update in the drawing without having to re-initiate the count from scratch

Load, strength and stress analysis

Load calculations and analyses are an integral part of Engineering Design. Such work is neither monotonous neither voluminous. Hence, this activity is added to the Scope of an Engineering Outsourcing Services Firm that has the expertise in Engineering Design.

Bid documentation and cost analysis

Bid documents for Engineering Services are lengthy documents with detailed specifications. Many Engineering Outsourcing Services Firms create a name for themselves by specializing in this documentation. Apart from regular documentation-friendly resources, it also requires special techno-legal experts. Once the firm also acquires region or state relevant knowledge, they become even more valuable as an Engineering Outsourcing Services Firm.

Bids submitted by prospective vendors need to be analyzed. Apart from standard activities of entry checking, specification adherence and comparison of rates, an important Scope of work is cost analysis and value engineering. Alternative techno commercial proposals given by bidders   must be reviewed by competent and experienced engineers, who then send specific recommendations and queries to the client for decision making.

Project Management Support

While Project Management is a very hands-on field that limits the opportunity of Outsourcing, many clients are sharing their workload with Engineering Outsourcing Services Firms on specific activities like:

  • Planning and scheduling
  • Tracking
  • Report generation
  • Recording
  • Alerts
  • Documentation and reports

Summarily, this article covered a practical and on-the-ground report on Scope of Engineering Outsourcing Services Firms.
