What does a structural engineer do?

A structural engineer is responsible for the stability and integrity of a building. This path typically requires a Bachelor's degree in Civil Engineering with a specialization in structural engineering. Many pursue a Master's degree for advanced knowledge. Licensure as a Professional Engineer (PE) is essential for independent practice.

Their primary tasks include:

Calculating loads and forces

Structural engineers assess the various loads a building must withstand by performing a structural analysis of a given structural member in the project.

This includes dead loads (the building's own weight), live loads (occupants and furniture), and environmental loads (wind, snow, earthquakes). Accurate load calculations are essential for ensuring that the structure can support these forces without failure.

Selecting suitable materials

Different building materials have distinct properties, and structural engineers must choose the right materials for each part of the building.

For instance, steel might be chosen for its strength and flexibility, while concrete might be selected for its compressive strength. Engineers consider factors such as durability, cost, and local availability when making these decisions.

Designing structural elements

Structural engineers design the building's skeleton, which includes beams, columns, foundations or footings, and other load-bearing elements.

These components must be precisely calculated and designed to ensure that they work together to provide stability and safety.

Creating detailed drawings and calculations

Engineers produce detailed structural drawings and calculations that show how the building will be constructed. These documents are essential for obtaining building permits and guiding the construction process.

Structural engineers play a critical role in ensuring that buildings are not only functional but also safe and compliant with building codes and standards.

What does a structural drafter do?

A structural drafter (traditionally referred to as a draftsman or a draftsperson) transforms the engineer's designs into detailed technical drawings.

An Associate's degree or technical certificate in drafting technology is a common route to becoming a structural drafter. Employers often seek proficiency in CAD software like AutoCAD and Revit.

Their responsibilities include:

Creating blueprints

Drafters produce precise drawings of structural components, such as beams, columns, and foundations.

These blueprints serve as the primary reference for construction crews to read and refer to and are essential for ensuring that the structure is built correctly.

Detailing specifications

Drafters include material specifications, dimensions, and construction guidelines in their drawings. This information ensures that builders use the correct materials and follow the specified procedures during construction.

Ensuring compliance with building codes

Drafters must ensure that the drawings comply with local building codes and standards. This involves incorporating all necessary regulatory requirements into the plans.

Utilizing CAD software

Modern drafters use Computer-Aided Design and Drafting (CADD) software like AutoCAD and Revit to create their drawings. These tools allow for greater precision and efficiency, as well as the ability to easily make changes to the designs as needed.

Structural drafters play a crucial role in translating the engineer's calculations and designs into actionable plans that builders can follow, ensuring the successful execution of the project.

Some companies invest in training experienced drafters to perform design calculations for non-complex projects involving simple structural elements like beams and columns. Structural design tools like ClearCalcs can significantly streamline this process, reducing errors and saving the project review engineer valuable time.

How do structural engineers and drafters collaborate?

The collaboration between structural engineers and drafters is a multi-step process that involves close communication and coordination. Here's a look at the key stages of their collaboration:

Initial design

The collaboration begins with the initial design phase. During this stage:

Concept development: The architect or project manager develops the initial architectural design concept for the building. The structural engineer is brought in early to provide input on the feasibility of the building design. For example, if the architect envisions large open spaces, the engineer will assess how this impacts the building's stability and suggest ways to reinforce the structure if necessary.

Preliminary load calculations: The engineer performs preliminary load calculations to ensure that the basic design can support the expected loads. This involves assessing the initial design's structural requirements and identifying any potential issues.

Sketching: The engineer begins creating preliminary structural sketches. These drawings help visualize the initial design and identify any potential conflicts or areas that need adjustment.

Detailed Planning

Once the basic design is approved, the project moves into the detailed planning phase. During this stage:

Structural calculations and reports: The structural engineer conducts detailed structural calculations and creates comprehensive reports. Tools like ClearCalcs are invaluable at this stage. ClearCalcs allows engineers to automatically generate detailed structural reports from the calculations in a given project that are easy to review.

 Load path tracking: Load path tracking is crucial in a structural engineer's workflow because it allows them to visualize and verify how loads are transferred through a building's structural system - from the roof down to the foundation. This understanding is important for ensuring structural integrity and safety. ClearCalcs' load linking feature ensures that any changes or revisions in the design automatically update the load calculations. This prevents errors and saves time by ensuring that all calculations remain accurate and consistent throughout the design process.

 Standards references: Referring to relevant building codes and standards is non-negotiable for structural engineers. These codes, like the International Building Code (IBC) or Australia's National Construction Code (NCC), represent minimum requirements for safety and performance.  ClearCalcs streamlines this critical aspect of structural design. Every step in the calculations is referenced and linked to the latest building codes and standards. This ensures that the design complies with all regulatory requirements and provides a clear rationale for the calculations and design decisions.

Collaboration on detailed drawings: The drafter creates detailed drawings based on the engineer's calculations and reports. These drawings include all necessary dimensions, material specifications, and construction guidelines. The drafter and engineer work closely to ensure that the drawings accurately reflect the design and meet all requirements.

Construction Documents

The next phase involves finalizing the construction documents. During this stage:

Final plans and drawings: The structural engineer and drafter finalize the detailed plans and drawings needed for construction. These documents include structural calculations, material specifications, and safety guidelines.

Material selection: Using ClearCalcs, the engineer and drafter can easily change materials if needed. ClearCalcs allows for quick transitions between different materials, ensuring that the best options are used for the project without wasting time retyping inputs.
