What is a Delegate Engineer?
A Delegate Engineer is a licensed Professional Engineer (PE) entrusted with a defined scope of work on a project. Acting as the engineer of record for that scope in particular, they are responsible for producing, signing, and sealing their own drawings and calculations.
They must also coordinate closely with the overall building Engineer of Record (EoR) to ensure their design is safe, code-compliant, and fully integrated into the overall project. Delegate engineering must be approved by the EoR for the project.
In essence, the delegate engineer is the specialist whose expertise ensures critical portions of a project are delivered with precision and accountability.

Do Delegate Engineers Differ Between States?
While there may be slight variations in specific requirements or regulations between states, a delegate engineer’s core duties and qualifications are likely to remain similar regardless of location.
These differences are usually related to licensing requirements and industry practices based on the respective state.
What is an EoR and what is their role?
The Engineer of Record is a professional engineer who is officially responsible for the design, analysis, or evaluation of a particular engineering project as a whole (such as the primary structure).
The EoR typically oversees the delegated engineering aspects of a project, ensuring that they meet applicable codes, standards, and specifications.
These include design oversight, code compliance per location, quality assurance, coordination, documentation, permitting approval, and construction support. Sometimes Architects of Record serve in this capacity.
Relationship between the EoR and the Delegate Engineer:
The EoR has no universal definition, however they have similar attributes.
An EoR is defined as “A licensed professional engineer who is in responsible charge for the preparation, signing, dating, sealing and issuing of any engineering documents for any engineering service or creative work.”
If the EoR wants something installed, such as a canopy on a building, he could hire or work with a delegate engineer, who could do the engineering solely for the desired canopy.
The delegate engineer would then create and seal the plans and calculations for the canopy.
The EoR would be responsible for ensuring that the building has the structural capacity to support the canopy.
In this case, the delegate engineer would only be liable for the canopy and its connection to the building, and the EoR would be responsible for the building’s ability to support the canopy and the integrity of the substrate the canopy is connecting to.
Why hire a Delegate Engineer?
- Shared mastery of a specific component of the structure – Hiring a delegate engineer ensures multiple experts contribute to the project.
- Higher design accuracy – More experienced minds involved means the structure is more likely to be properly designed, considering all aspects and history of similar work.
- Specialized expertise – Dispersing tasks among engineers with different niches allows for a deeper understanding of the project.
- Complementary skills – The Engineer of Record (EoR) may focus on building dynamics, while delegate engineers may specialize in specific elements like windows or canopies.
- Collaborative innovation – Combining collective experience enables engineers to design and innovate to the best of their abilities.
